Single Turbo Question

[fastsupra]

Wow thats an insane amount of great information! Thanks a ton! Maybe I will run a full tank of race gas a see how it feels Also, if you do run race gas even if its only 5 gallons, do you need to get your car tuned for it? Or can you just dump it in and drive?

Please keep in mind the power comes from the boost, and not from the octane. The additional octane is only there to prevent detonation.

No need for re-tuning when adding race fuel. It burns like regular gasoline, because it is regular gasoline - just gasoline with a high octane. However, if you were to (for example) dump methanol into your gas tank, that would require re-tuning.

Just dump it in and drive.

Ok sweet Im going to have to put in a full tank of race fuel and feel the power

One last thing about octane and boost, when I run my methanol injection kit with 93 octane gas in my tank, about what octane will my fuel be? Like on your chart you posted, how much boost would I be able to run?

I'll assume this is the kit you're planning to run:

I'll also assume you're planning to run EITHER:
- A 50-50 mix of pure Torco methanol and distilled water
..-OR-
- Snow Performance "Boost Juice"

HOWEVER, even knowing those variables, all I can do is give you a decent guess. My best guess is that you'll be fine up to about 22psi...which is about a 'net' 100 MON. Please only take this as a rough estimate, and carefully tune your max boost with the methanol kit, ideally using data logging from your knock sensors. When you figure out the exact answer, please post back here - I'm very curious!

Lastly, I'd also recommend you mix something like this with the methanol+water:

Yepp thats the kit I'm running and I will be running Boost Juice.

So Would 25lbs be out of the question? Why should I add those to my tank?

25psi may be possible but I wouldn't start there. I'd suggest starting your tuning process at 15psi, be sure your methanol is spraying, and go up from there one or two psi at a time while checking your knock sensors on each run. You should also tie the methanol kit's low-level sensor in the methanol tank into your ecu/piggyback/etc. if possible - to (for example) auto limit boost or auto retard timing when the methanol runs out.

The upper cylinder lubes are to help protect the injectors and upper cylinder/head components from the potentially harsh/corrosive effects of methanol.
