Brian's new boat

[Chris LaPanse]

Well, Brian (BMAD01) has a great new boat that he sent me some pics to post, and I have to say it is a thing of beauty. It is a blast cat with a QD25, and I have to say, it looks like a real screamer. I can't wait to see it on a saturday real soon at Engineer lake, but for now, here are the static pics he sent me:

[BMAD01]

Thanks Chris! I do'nt have a picture reducer anymore. I reformatted my computer, and have left alot of stuff out. (on purpose) Yep, it's an AC Blast cat. I've put one of thems new Quickdraw Z25's in er. It's also got a Marine Specialties, "Zero Slip" clutch, and their water pump too. I fired er up yesterday, with a garden hose attachment for cooling. Ran like crap :eek: , till I dialed in the carb. ;) Then I ran the engine for about 5min.. Looks like it's a GO for Saturday morning! Hope ya like er, I do! :D :D Brian

[water dog]

Wow !!!.Thats some serious horsepower!!!.

[BMAD01]

Yepper! Q/D said they were gettin 7.4hp otta this engine @20,000 rpm, with a WT- 257 carb,(I got) A fuel pump, (I got) their pipe, (I got)and Racing gas. (I got) Soooooo,,, Things otta be interesting HUH?? Brian ;)

[Doubledog]

Nothing but beauty. Next step of this is showing some action shots.!

[countryrook]

wow nice boat man great job cant wait to see it rock!!!

[BMAD01]

I'm gettin that all together fer Saturday morn.. Gonna charge all the batts fer the boat Friday, Camera included. Should have a bunch "O" pics. Got a gallon of 108 octane racing gas mixed up with Honda HP2 racing oil too! I'm ready guys! :D :D Brian

[Doubledog]

I'm ready guys! :D :D Brian

WE'RE READY TOO !:D

[FlyerCAN]

Just One Word...
Awesome!!

[rico3]

well BRIAN ....how many cats you got now m8 ??? ;) ;) ;)

[BMAD01]

I've got 2. The Stryker will have this weekend off, so I can concentrate on "dialing in" the B/C. Next week will be different tho. By then I'll have extra r/x crystals. Then I'll be able to have both boats on the same channel, and just switch from "model #1" to "model #2" on the t/x! Won't that be a hand full? :eek: :eek: :confused: :confused: :o :rolleyes: ;) :cool:

[badd_maxx.25]

who makes that hull, it looks good

[rico3]

what speed are you expexting BRIAN with your new BLAST CAT and QD25??? did you get it in (READY TO RUN )or you build it yourself??? ;) ;) ;)

[Burkey1000]

dont forget if ya gonna use really high octane fuel the timmimg should be retarded slightly to get the max out of it, you can retard the timmimg on the new quickdraw for that reason, should go really well, is the motor stock or tunned, a tunned one will spin up to 20,000 rpm if set right, ya best put a long rope on here she might just take off lol :D

[BMAD01]

Burkey....I'm runnin 108 octain gas. And the timing has 3 positions. #1 is for regular gas, or stock Zenoah timing. #2 is 5* advanced, this is where Mitch says the engine runs best, with their pipe and high octaine gas. That's where I'm at. #3 is 10* advanced, Mitch says they did'nt have much luck at this setting. The engine would kicks back hard at this setting. I took er out yesterday and ran it for the first time. It ran like crap! :eek: I've talked with Mitch about the problem since. It seems I'm not getting enough spark to the plug as a result of a bad ground on the secondary coil. I've run a ground wire from the coil to the engine case, and bolted it down. Going back to the lake today an test er out again. I've got NO rpm, or speed stats yet. I'm on a waiting list for a 30,000 rpm tach(can't remember the co. name) I should have in about 8 weeks. We're just trying to get er ta run decent right now. Gotta tell ya tho, havin a clutch on this rig is just about the coolest thing about it! Ya fire it up, then leisurely place the boat in the water at an idle. KEWEL!! :D :D HA,HA,HA! Brian ;)

[Burkey1000]

yep thats the good thing about the quickdraw the you can adjust the timing on it, go to see someone is giving good support for ya boat. As far as the spark goes, i always run an earth lead to the case, alot of the mounts you buy ie, the coil relocator, uses the bolts to ground the coil, then the bolts form the mount to the case, not good, earth lead is always a surfire thing, get it SUREFIRE THING, think i must be tired lolol :D

[rico3]

hey brian when you get your new blast cat sorted will you be running a modded prop? :D :D :D

[BMAD01]

Right now, I've got 6 different props. All but the 6717/3, are modded. Finding the right one is the "trick" tho. Nothing but trial and error. Brian :o

[rico3]

hi Brian...... do you always use (reccomend)the QD HOT PIPE and SILENCER when using a QD engine.... i couldnt tell by the pictures if you are using the QD OUTPUT FLYWEEL as well??? ;) ;) ;)

[BMAD01]

Here's some interesting reading. I think you'll find yer answer in the last post. Brian


http://p086.ezboard.com/fjimsrcboatdockjimsrcboatdock.showMessage?topicID= 19087.topic

[Burkey1000]

Just reading that on jims dock about the mix and the link you had there, why is then you use 10oz of oil, i know it helps compression, but at what point does it affect the burning of the fuel, ive used 89 octane and 97, with anything between 4 oz and 8 oz, with 8 oz it was a nightmare to start went to 5 oz problem sorted, also 8 oz fouls the plug aswell, it never runs the right colour, just like on the jims dock post, i used to have motocross bikes and road bikes, and always ran 5oz, you can go right down to 50/1 on good synth oil, not saying i would but all the racers on the bikes and carts go down to at least 40 to 1 an have no probs, just thought i would through a curve ball in there to see what answers come up, as none were realy given, jack armstrong from jack armstrong racing has ran racing bikes and carts for about 30 years and the carts spin almost to 20,000 rpm, one more thing, the oil these days is that good at its job, on a new engine why doesnt anyone use a running in oil, while running in, the engine should wear a little to bed it in, then use a fully synth racing oil, but no one does, otherwise the bore just galzes right away, and the ring never get a chance to bed in, enough there to start something i think lol :D

[BMAD01]

GEEZZEE BURKEY! That was a mouth full! LOL I suppose the amount of oil you're gonna run, depends on what kind of engine you got. Lohring said, in the last post, that the Z25 had an increase in power with 10oz/gal.. I dunnano what kind of engine you have, if it's stock or full/mod. My Stryker has a full/mod, M+D G260 in it. I was running 8oz, of HP2 in that. But things have changed in my boathouse, and I have only 1 gas can. So it looks like I'magonna see how it runs on 108 octaine, and 10oz. of HP2. :rolleyes: Brian ;)

[Burkey1000]

i run a tunned zenoah g260 it quick ask ricco lol, the more power comes from a very slight increase in compression, the thing is unless we going for records does it matter, would we realy notice a diff in the boat, i doubt it and if we did, i think it would be time to get a cyl and piston, i will have to look at the handbook see what type of clearence they use from cyl to piston maybe. the zenoah ran 58.7 mph with 5 oz of oil. The oil i use is made by rockoil, racing synthesis 2 fully synthetic, i dont use anything else, and my baot prop gets used more than most on here. :D

[rico3]

i dont think your modded ZANOAH is faster than mine ..lol but it will be if you get QD the conversion kit for your ZENOAH G260... it seems like things are hotting up down the lake m8...anyway dont forget its another LYNX BOAT with a full modded ZENOAH G260with 6.9 bhp thats to beat.....so it looks like you will need the QD conversion off your girlfriend for yah birthday dude...And you can always get the QD HOT PIPE aswell that(MAY) give you more speed....ps i got 2 more props m8 today .. 2 blade and a 3 blade.... hope this give me a little more speed,cya SUNDAY M8... opps just had a look on BONZISPORTS web site and the BZX4 mod G260 is only 5.5 bhp so your own modded engine might be faster than mine dude :eek: :eek: :eek:

[Burkey1000]

mine isnt faster than yours lol, your having a joke arnt ya, im across the lake before yours picks up lol, ok for the forum lets put it to the test, race on sunday it is, are will you shy away from defeat, im up for it, are you, guess your forgetting the gps readings aswell or does it only work right when its in your boat lamo, and mine kept up with buddas to, and its a 2 year old engine, but not anymore, new cylinder and piston,and ring, we shall see, no need for a quickdraw, the mods on buddas is very basic, im just scratching the surface theres alot more to come, and its my own pipe, all my own work, the crown will be mine im sure of that. :p

[rico3]

nice one m8... will cya down the lake at the weekend ;) ;) ;)

[Burkey1000]

GEEZZEE BURKEY! That was a mouth full! LOL I suppose the amount of oil you're gonna run, depends on what kind of engine you got. Lohring said, in the last post, that the Z25 had an increase in power with 10oz/gal.. I dunnano what kind of engine you have, if it's stock or full/mod. My Stryker has a full/mod, M+D G260 in it.

So it looks like I'magonna see how it runs on 108 octaine, and 10oz. of HP2. :rolleyes: Brian ;)

To run high octaine fuel above 97 you need to advance the timming, and you cant do that on the 260s only the new quickdraws.

[Burkey1000]

ok this 10 oz thing, we all know you get a slight increase in compression, but would you notice it on the lake, i dont think so, also what increase would you realy get, 1 maybe 2 psi, not worth it, drop the cyl on its ass compression goes from 145psi to 185 psi instant power and you would notice too. second running 10oz of oil, is the inside of ya pipe wet with oil, it should be dry carbon build up not wet, if its wet then the combustion isnt full, ie it cant burn it, therefore, if it aint burning it, it aint throwing that piston down any faster is it, a loss of power, the oil is just getting thrown out the pipe, next thing is the word power, power= speed to a degree but is only a very small part of it, why do you all want to go to 10oz, to get more speed i bet,funny word is SPEED, i bet i could come up with an idea for a gizmo, and sell it on e bay, and make money, just by using the word speed, now theres an idea, yet everyone forgets the easy way to get speed, look at f1 cars, bikes and boats, just think about it for a moment, its called power to weight ratio, have a look at all your boats, dual rudders big heavy drives, trim tabs, have you tried it without them, i bet not, if the hull is any good you should get it to run by adjusting the prop height, have any of you had the boat where its going on full throttle and its rocking from side to side, getting worse the quicker it goes, and i bet the first thing you do is fiddle with them, did you try taking them off, i bet it stops it, turn fins, 5 inch rails to hold everything in, a very heavy way of doing it, fiberglass hulls, very heavy, not that strong and not very ridged, big battery packs, big 1/4 inch servos, you can get standard size servos with the same if not more torque than 1/4, this is just a fraction of it,and lets not forget the mods on race engines that you buy isnt all that can be done to it, i doubt its the same mods the pros would use for themselves, why wont they sell them, because you buy one open it up and the secrets are there, thats why, if its more speed you all want, take a step back, look at your boat and dump all the heavy gear get a nice light hull epoxy are carbon, build it as light as you can, dont put anything in there that it doesnt need to run, try it without the turn fins and tabs, use a very light drive and it will blow all the others away, simple as, and as far as cost, work it out, all the money on oil every weekend, the cost of high octaine fuel, it will soon pay for itself and the future running costs will be cheaper, it wont use as much fuel, and everyone will wonder why its so dam quick, looking for speed by putting more oil in is like farting in the wind, it a wast of time no one will notice it, and neither will you, exept for your wallet. All you need is enough oil to do its job and no more,you hear the gossip, z260 doing 107mph, true yes, how much oil did they use, 8 oz, true yes, but what timmings is there engine, as high as 186,190, maybe more, almost to bursting point, nothing like what your supplied as your rtr race engine, if your going for speed records then yes because all of the above would already have been done, but i think its time people got back to the basics because thats what were all doiing wrong and thats where some of the biggest gains are, and thats what sorts the men out from the boys, the people who think and cover all the basics first, were forgetting the basics, and thats why the people who do it WIN. Enough said for one day i think, dont want to give any more away, dont mean to offend anyone, just trying to get people to sit back and think about what there aim is and how the best way to get there is, but for speed, if ya think 10oz and high octaine fuel is the way to go,and it was a simple as that, then we would all be world record holders. Im not saying more oil doesnt work, it will in the right instance but not for 99.9% of us on here.Come on DD you should know what im getting at, lets have some views on this.

[BMAD01]

Ok guys! I had a major setback with the Q/D Z25. :eek: It seems Mr. Bruce Hanson, do'nt know how to match an insulator block to the Q/D intake port. When I took er out the first time, the engine was a coughin, and a weezin, and a spittin, a big ugly mess of unburned fuel out both ends, all over the innards of me brand new boat! :mad: I talked to Mitch, at Quickdraw, and ended up sending the engine, and pipe back to him. He could'nt believe the shoddy workmanship that Hanson did to my engine. He then fabricated a new insulator block, matched er up to the port, and dynoed it with my pipe! He said, with the modded 257 he put on er(now my newly modded 257) he got 6.8hp @ 20,00rpm. And with a WYK33, he got 7.6hp! Gadds dudes! Thats my engine! :D :D Then he said, (quote) "I'm only going to charge you for shipping", "If you'll promise to run this engine on VP-U2 racing fuel". Needless to say I've gotten the VP-U2 fuel. ($68.00 5/gal) Had er out to the lake today, running an Octura X470/2 prop. I now know that the rest is in my hands with the setup. I'm not running a tach yet, but the gps was at 46mph. Gonna look into a bit smaller prop with the same pitch. But LOOKIE at the holeshot from a dead stop! This engine's got some poop! Brian :D :D

[BMAD01]

Sorry guys, I forgot about this sites "wimpy pic size needs"! LOL This is from a dead stop in the water w/clutch! She do got some poop! :D

[BMAD01]

On da water

[BMAD01]

another

[Chris LaPanse]

Looks good. Can't wait to see her run (maybe next sat?)

[Burkey1000]

not trying to put things on a down side but 46mph out of a quickdraw thats putting out 6.8 brake and 20,000 rpm, and in a cat something is wrong somewhere. you should be getting mid to high 50s. we have lynx 47s that will do that on a standard g260pum, and the lynx is a mono, you sure your gps reading was right. And going to a smaller prop is a no no. not with that engine, it should scream with that prop.

[Doubledog]

This Blast Cat is something else.! I see one gracing my shelf someday:) Dial that baby in Brian & lets get some #'s.

[FlyerCAN]

I'm no expert in boating and I also thought that going to a smaller prop would be wrong with all that horse power. Go bigger if anything. Shouldn't he?

Chris

[Micho523]

How about slightly smaller, more blades and increased pitch?

also, try an x475 and an x470/3 or even with that qd an x572/3

[BMAD01]

Ya gots ta prop these engines fer 18,000 and up! They are absolute screamers! They make their power at the higher rpm, and hold it. That is what a Q/d is all about. Whereas a full/mod Zenoah will make it's max hp around 16,000, then start to loose hp the higher they rev. Imonna leave this X470 on er an raise the strut WAY up, an see what happens. I'll also have an X470/3 ta try out on Saturday. I've also got 3 new props on da way fer the Stryker I can try on it. They are 7016/2 mod, a 7016/2 mod with added pitch, and a 6717/3 mod. I gots nothin but time guys. Ifin I gets tired of messin with the B/C, I'll just fire up the Stryker! EHH! EHH! Brian ;)

[ejp]

Almost like a nitro??? As soon as I go through the 4 gallons of fuel I just bought I'm going to sell everything and get a gasser. Just thought I let you all know that:D

[Chris LaPanse]

Really? Which one?

[ejp]

right now I have no idea, I think I want a fast catamaran style hull, Maybe a stryker.:D

[Chris LaPanse]

Well, I can tell you - a stryker with a mod 260 DEFINITELY fits the bill for a fast cat.

[Burkey1000]

with 6.9 under the cowl you cant tell me it wont rev with a 275 on it, if it doesnt the engine figures are wrong. get a hold of the 572/3 from octura, mod it and it should fly.
Ive got an epoxy lynx 47 mono, my own tunned g260 and pipe, i modded the 572 and i revs all the way to nearly 60mph, spinning around 17500 rpm, so the quickdraw should handle it no problem and its a cat. In saying that i know of 2 cats at our club that just dont like 3 blades, so try a prather 280 cut down to 275 size and moded, that will give you the pitch and should rev no problem. Remember it a new motor let it bed in first, dont put to small of a prop on so it screams and just shags the engine form the start. as for the g260 running out of bhp at 16000, it all depends on how you mod them, you can raise the exhaust timming and intake timming to rev high but do a chisel cut profile on it, widen the exhaust port and intake to give loads of torque and it will pull strong all the way to 18000 rpm, a long rear cone with a small dia stinger pipe will let it over rev and hold the power there aswell, and tune the pipe lenth for the high rpm. I know one person who can easly get 8 or 9 bhp and nearly 20,000 rpm out of a g260, but there only any good for racing, there far to peaky, ya gotta full throtle them all the time but they scream. so it can be done, its just know how. To get the max outta a quickdraw you need a fuel pump, and a wyk33 carb about 150 bucks. there is always more that can be done. Also try a better plug the standard cmr7h etc are crap, try a NGK CR7HIX plug. Its a full size plug so it will be higher, but its got an 0.6mm dia iridium centre electrode, much better sparking, which means a better burn. One other bonus is they only need about half the voltage to spark so it makes ya coils last much longer too.
If you want the best money can buy Denso do an iridium plug with a 0.4 mm centre electrode, and they have a u groove in the bottom electrode, to give an even better spark and need even less voltage to spark, but they cost even more. The code for the DENSO is IUF22. :)

[BMAD01]

Could'nt wait till Sat! LOL I raised the strut 3/8" up, form the bottom of the sponsons to the bottom of the strut. She's revvin "much mo better". And the hull is running pretty wet as a result. I did'nt gps er,(only stayed out there 1hr) but I think it's faster. The X440 I'm using is borrowed. It is very dull, with alot "O" battle scars on it. And the tips of the blades have been cupped about 1/8". And I'm sure it's never been balanced either. I'm getting really sick an tired of shellin out $60.00 +, fer a modded prop to find out it do'nt work, after waiting 4 weeks + to git it too! :mad: I've got a new balancer on the way as I type. A set of "cupping pliers" on the way too. And "Mike Tyson", sent me drawings to make my own pitch gage. :p Looks like I'll be a do'in me own props from now on, very soon! ;) Brian :)

[Chris LaPanse]

X440? You're using a 40mm prop on a QD?

[BMAD01]

X440? You're using a 40mm prop on a QD?


DUUHH! Sorry Chris, It's an X470. Oh yea, I got the "go ahead", to git rid of the cups on it last nite. So here come the pliers! Brian :rolleyes:

[Chris LaPanse]

Ok. Next time I'm down there (a week from Sat), you can try DD's modded X470/3 if you want (as long as that's OK with you, DD). It seems to run REAL well on my boat, so maybe it'll work for yours too (after I get some #'s on mine, of course)

[BMAD01]

Well,,Gee,,Uh,, I'll have my own "modded" X470/3 by then. Thanks anyhow, Brian :rolleyes:
