hyper mod section....

[the WaTeRhAwK]

for people that want to press the life and longevity of their engines to the edge of the envelope for performance...LOL nitro/alcohol, NOS setups, etc...

[h2odesperado]

i figured out how to understand travis... :439:

i know someone was runnin NOS on a red ski in daytona. I wanna see that setup.

[IN2-H2O]

I snagged some pics of that ski on Sunday.

[tom21]

who needs power adders when you have the extractor exhaust system?

my setup - 20 minutes, low heat on tumble dry.:burnout:

[wayne]

i use fabric softener for pre-filters.

it keeps my extractors extracting with that spring-fresh scent.

but you have to use the sheets not the liquid stuff.

but the liquid stuff would make the inside of your engine soft and cudally.:thewave::thewave:

[WFO Speedracer]

Justin did say that SFL's ski smelled wonderful

[WaveDemon]

thats a great idea. we could sticky waterhawks 212hp x2 in that section!

[PancakePete]

that NOS setup... you could not pay me to even stand next to that....

Scarys me silly... I crap my shorts when I hear a backfire.. LOL

:dance:


Plus what do you need that for really. Its cool but not really practical.

Not knocking, just another thing to blow up.

[madscientist]

take it to the hydrodrags

nah, usually they just throw a rod out through the belly pan and hull, and fill the engine compartment with water. the only time I've ever seen anything happen up top is where we had to drill the jets out to run enough alcohol to keep them from melting, they would foul a plug allowing the cylinder to get too much raw fuel and hyrdrolock at high rpms, it causes the head to pop up and rip the studs out of the cases, or waste the mounting flange on the bigger jugs.

Was that before or after you drank all the alcohol & huffed all the nitrious:naughty: WAD:headbang::headbang::headbang:

It's pretty amazing that once you fouled a plug, the engine ran long enough to fill the bottom of the cases with enough liquid fuel to finally backfill into the top end, and then run with enough RPM (with one plug) to actually shove enough fuel on top of the piston that didn't run out the exhaust port to hydrolock it.

Amazing!

At what point did you wake up?

the fuel goes in through the transfers, matt. it really IS "amazing", isn't it. :rolleyes:

when you run enough alcohol in a nitro setup to keep it cool, you're not running traditional jets. we throw those away, and drill out the enclosures to 1/16th or 1/8th inch. there is a "ton" (by comparison) of liquid fuel going in and up through the transfers. they're so sensitive that the sun can go down, changing the atmospheric temperature and make it run too lean. these aren't your "typical" setups, matt. get that out of your head now...LOL

anyway, the problem with nitro/alcohol setups is that when they're running extremely high rpms it's difficult to tell when you're only running on one cyl, and by the time you figure it out it's too late.

no sleepy, and no huffy here...lol

how do you so precisely drill those holes with no jets?

I wasn't dogging you! I am amazed, is all!

You must have been flowing gallons through there if it filled up to the point of locking and not running out the exhaust port.

What RPM?

And what happened to the rods?

on the regular Bn 38's just past the enclosures get drilled. the 0.6 "plug" is removed and drilled out, you have to enlarge the throat holes as well. the holes are as "precise" as you are with the tool..lol


throttle response is comparable to a gun going off. basically, regardless of curve you have a "light switch" motor. there pretty much is no curve.

it doesn't fill up the cases, it just collects in the chamber due to extremely high rpms and no fire to keep it burned off before it locks. it all happens very quickly, from the time of foul to being done. some of it does run out the exhaust port, but it's not enough to drain it off in time to keep it from locking. the rod is usually bent or broken in half, or broken sticking out the side of the cased locked up against the starter, studs ripped out of the cases and/or cylinder. these little 440/550 engines can top out around 11,000 without flying apart, but that's not a sustained rpm, either. they will definitely exceed their harmonic frequency at a sustained setting that high, but that's much more centrifugal force than a 650 or larger crank can handle without flying apart.


that's nothing, I've seen the things just plain melt to a solid chunk of crap due to a lack of alcohol. I've actually seen people do that from time to time...lol(that's really not very funny.)

[Matt_E]

Tell me more about harmonic frequency, please.

I have also seen certain threa, errr things melt into solid chunks of crap.

I am going to bet this thread will make probably 55 post's before anyone gives up lol

harmonic frequency limits. it is the actual rate of movement that a composed apparatus can handle without decomposing. when it exceeds those limits, it's done.

Who needs jets when you's gots drillbitz? :biggrin:

[the WaTeRhAwK]

super bn's weren't out at the time we were doing those mods, matt. however, you are correct, the mods to the carbs would've been more concise, but the throttle bodies would need to be drilled, regardless. the bn carbs worked just fine. 1/16th to 1/8th holes were drilled depending on what nitro percentage mixture you were going to run. the 1/16 holes didn't allow enough of both fuels to get enough cooling from the alcohol, so when we got up to 1/8th the low rpms would allow too much fluid, and usually hydrolock one of the cylinders if you didn't keep it hammered. lot's of fun.

[Matt_E]

Today's Lameys and other big power engines probably wouldn't hold a candle to those old school nitro gizmos, eh?

actually, I would be interested to see what a pv motor would do setup like that.

I would like to have a pv 550 setup..lol with a crank that spin in 11,000 rpms, holy crap!!

ha! 50th post!

well, here's some 750 cases I ripped to shreds pourin' nit/alc through an mrd fuel inj sys. I need aluminum welding skills for sure :newbie:, but I think I got everything lined up decent. gonna have fun with the dremel...lol
that's nothing though, I've trashed and seen them trashed a lot worse than this...

[the WaTeRhAwK]

here's a nice 440 nitrous setup if anyone is interested in buying it...

[Maxumflux]

1/16" or 1/8"?

those are very precise fractions your throwing at us.

maybe you shouldve used super BNs since they have removable jets..... but then the following settings would be useless:

15/16 of a turn on the top
1 and 1/8 on the middle
1 and 5/16 on the bottom
