Never before has so little power been made from so much displacement! (Page 21 of 57)

Couple interesting points about the difference between cars and planes
> Auto engines run at a minuscule % of load, while aircraft run 70%-ish all the time and more on take off - thus aircraft engines are a LOT more robust than car engines - Given the much lower power loading, yet still at A/C RPM settings, this thing should have LOTs of heat capacity available just through radiation/convection.
> A/C usually have very tightly cowled engines and don't get that great a cooling - probably the MR2 cools dang near as well (for some of the cylinders anyway) - easy answer is to put a flow deflector on the roof - that will help some.
> Auto engines need lots craziness to accommodate the driveability needs of constantly changing RPM and load, and planes don't - hence Mags and manually set timing is fine for A/C. EFI and electronic spark control are really beneficial when putting a plane engine in a car!
> Reciprocating mass in the A/C engine is quite a bit higher - good for smoothness behind a prop, but may make for very slooooow speed changes in a car... may take lots of shifting!

Anyway, should be fun, and is the most interesting Lemons project to date! - far harder than splicing cars together or even twin engines!

Looks great Marc!  Can't wait to see and hear the video of it running.

yeah, 6 ports strait into the manifold are for the 5 cylinders plus the feed line. the regulator has the return line on it.

not sure which one you're talking about but even the smallest wasp is a 450HP engine and the biggest is 4300HP (71.5L displacement, twin turbocharged and supercharged.

somehow i don't think the judges would let me on the track with 4300HP!

while i'm not saying i would not do this again with a different engine, i think i'd prefer to do the next outlandish project with a turboshaft engine.

also, if anyone else is thinking of doing a radial in a car, i'd definately suggest a low cylinder count motor. it's getting tiring to make 5 of everything. i'd be worse with a 9 cylinder or a two row 10 or 14 cylinder engine. though for what it's worth megasquirt could waste-spark control a 14 cylinder radial without a problem. you would just have to lie to the controller a bit

hehe, those turbo shaft engines have been on eBay since at least the beginning of this project. while comical to think about, it's slightly less than practical. it honestly seems like a good deal if i needed 7500HP

That wasp engine looks nice, when are you dropping it off? 500hp sounds quite pleasant.

you mean APU?

the hybrid route would be the easy way out. power to the wheels through a CVT transmission that is manually controlled by the driver is the way to do it

you would not once you realized how much work is involved.

that one would be significantly more complicated. the engine cannot straddle the transmission.

Somthing jumped out at me with your fuel rail and lines,
Are you running 45psI for fuel pressure? You might want to think about better line/fittings,
From your picture it looks like standard fuel line and clamps, I speak from experience that 45psi is too much for this type hose. NHRA won't let you run more than 12 inches total in a drag car fuel system with only 5 psi so I would assume with EFI this may be a problem.
Jay and the boys really frown apon fuel leaks and it would suck to see this back on the trailer for somthing that could be avoided.

Manny.
Elmo's revenge.

the line says right on it "Goodyear 50psi high pressure fuel line"

i'm using the non cutting barb fittings and hose clamps that are made to not cut the line. other than hardlines all around, there's not much extra i could do.

I believe what Mike 944 is referencing is "push lock" .
This is like what I was suggesting,(way cheaper than Braided)
Check out Jegs or Summit for the specs.

marc; wrt the wasp motor; we have a 98 CVPI, so I would probably do something less complex and involved than what you're doing. Something along the lines of running the OD gear direct drive to the tallest-ratio rear gear i could find and modulate it all with a clutch from a dump truck. My dad being a retired mechanical engineer could certainly work up something similar to how you're doing it, but I think even at your level to even attempt it with us would be ritual suicide.

still...want...wasp...motor...ignoring...insane...effort... drool!

anyway, back to the build. it's serious awesome in every way...cept that fan looks hella inadequate. Are you planning on shrouding the heck outta it?
