This run was on 130 octane airplane fuel, at 37psi. I suffered NO boost creep!

I think there might be more in 'er, but I'm not willing to push it. It's hella fast on the skreet!



All jokes aside, the build list is 100% correct. Just not quite ready to drop in the car yet, and I felt left out with all the dyno sheets flyin' around lately.

hehe...at least you could have had the HP/TQ cross at 5252 rpms...

[j-z]

arias for the DE are 8.8:1. you didnt list anything for injectors. why have the entire motor apart and not use a cometic? hows the ssac mani working out?

[KATwo40]

Currently on the car:

T3/T04E, SSAC, 38mm, 370's, SAFC2, Walbro255

I love the SSAC. Really. I get good response and full boost before 4,000rpm (and that's with just under 200k miles!!!) and no boost creep.

As for the Arias...They're 8.8, sorry about that. Thanks for fixin' me.

I'm not completely sold on the MLS gaskets. Fel-Pro head gaskets have been used for many years on LOTS of high powered drag cars, ranging from 500+whp Eclipses to 1,000+hp V8 nitrous cars. I also COMMONLY see threads that say things along the lines of, "...MLS gasket, and now it's leaking...gotta re-torque head....etc."

I'll get some real dyno sheets after the new engine goes in. It shouldn't be much longer. I'll be running 740's and the HybridKA daughterboard w/ launch control/2 step (already have that). I'll be sure to keep everyone posted.

Damn man that's impressive. What sort-o numbers are you shooting for in the future. How's the turbine housing to brake master cylinder clearence, did you modify it in anyway.

[KATwo40]

Shooting for a max boost of around 20psi to make 400wtq/400whp.

Brake MC clearance is nearly 0. It's VERY tight. While I have the engine out, I plan to shim the right side of the brake booster to c*** the whole assembly toward the driver side a bit. It shouldn't cause any issues.

If I got to Arkansas this year, my cousin crop dusts...I'm going to borrow some of his fuel.

[KATwo40]

I would advise against it. Aircraft fuel is very high in additives and lead. The additives that are in the fuel are usually harmful to automotive engine seals.

Just something to consider.

[darkforcejackal]

Wow...that torque spike at 3,500 RPM's must be "punishing"....to say the least...

Good luck on your project.

[jr_ss]

I'd get bigger injectors than 370's.

He has a f250 diesel. He would put in his plane fuel and then add 1qt of oil. High octane diesel. Truck went over 100k miles until something went wrong. Said he never had to change his filters....

[KATwo40]

That's very different from gasoline engines. I'm just saying that I wouldn't recommend running it in your car.

[hannibal]

I noticed the Arias 8.9 pistons, but kept reading.When i got to the 130 octane and 37psi, I began to have my doubts.Then the MS Paint dyno sheet made me LOL!

Now get the motor in the car and on a real dyno.

[WDRacing]

I just pee'd a little when I looked at your Dyno....very nice.

Avgas is fine to run in your car as long as you don't have a cat.It's best to run about 25% Avgas with the highest pump gas that you can get.What you end up doing then is adding lead to the unleaded pump gas which raises the octane of the pump gas, as Avgas is very high in lead, much higher that pump gas used to be.I do this all the time om my Porsche turbo which is 8.0 to 1 and with the turbo that it has and the build it will not run on pump gas alone.I usually run about 7 gallons of Avgas to 13 gallons of pump gas which out here in So Cal is only 91 octane.

Please elaborate on this. Why won't it run on pump gas alone? Not even on low boost?

FWIW: Here in my state, they won't let you pump Avgas into an automotive vehicle because of the lead content (pollution and federal laws against running leaded fuel on public roads...).

[drb930]

You are correct, it is the same here in CA, but i am a pilot with my own airplane, access to the airport and fuel pit.

My Porsche is set at stock boost which is .8 bar, about 11 psi, but i have raised the compression ratio from 7 to 8, and with the size of the motor now and everything else that i have done to it it will not run on pump gas alone without denonation.

I might add that the car is still a CIS injected engine which the injection is tricked out, but maxed out on fuel, there is just no more that it can give.

I will be going to a different manifold and an electronic injection system in the near future.

Avgas is "dryer" than pump gas as it has additives in it so that it will not freeze at high altitudes where the air is thin and cold.It also has a tremendous amount of lead in it, so dulouting that lead with unleaded is good for the car.Also before you run Avgas in your car make sure that your fuel lines are in perfect condition as Avgas is also much stronger as a solvent that pump gas with the additive package that it has for aircraft use, and it is very hard on rubber fuel lines.

Thanks,Dave

Ahhh, good ol' CIS. Forgot about those! I remember we used to deal with them in the SL cars (Mercedes). People would let the cars sit half empty, the tank would rust inside, then the CIS would fill with rust particles. Nasty.

You definitely need to convert to EFI so you can run on pump gas (and probably make more power in doing so).

Thanks for clearin' that up for me. Was sittin' here wracking my brain as to why your car wouldn't run on pump gas.
