PROcede V2 100 octane users

E90ice · 01-01-2008, 01:27 PM

So I'm supposed to race some fast cars tonight on a private race track. I was thinking about getting some race gas before I drive down there.

Here is my question: do I ajust the torque values to 100% imediately after I pump the race gas in...or do I wait for the car to adapt and then set the vaules to 100%?

Right now I'm running 92 oct @ 94%.

cn555ic · 01-01-2008, 01:31 PM

put the race gas in and drive it a few miles, then up the settings and drive another few miles and your set!!!! Go get him boy!!

E90ice · 01-01-2008, 01:41 PM

What if I just get some Torco or other fuel aditives? Same thing?

NPDAN · 01-01-2008, 01:47 PM

Not sure about the additives. I've never used them. I run 100 octane all the time and have my settings at 96% across the board. If you bump up to 100% make sure you report back on how the car ran... this is something Im thinking about doing...

For the record, 96% tq is fast as hell....

Dan, when we dyno your car, we'll need to monitor your boost and datalogs.
I'd like to see what power you put down on 96% settings, then up it to 98% and run a pass or two like that.

IDK, but for some reason, I don't know if I'd ever set it at 100% even running full 100 Octane like you do. Guess it's just the bit of protectionism in me.

BTW, Ice, I agree put the race gas in and drive it a few miles first.
Then pull over and move the settings up to 96%.

Unless your Octane with the mix is above 96, I don't know if I'd go above 97% on the torque settings.

Have fun.

i agreed with ya on additive. i have tried 2 bottle of additives from different company. It does not work at all. well i dont feel it. I still believe on normal race gas. But in california, we have 91 only . Race gas cost too damn too much

any engine will run on 103. vp have 109 unleaded. DONT RUN LEADED GAS. Unless you want to spent $$$ on o2 sensor and clean out your exhaust system completely.

AltecBX · 01-01-2008, 02:46 PM

Running that kind of high octane 99+ clogges up ure catalyst and messes ure O2 sensors. Anybody willing to race with that kind of gas, should have a straight pipe to the back, removed the catalyst. Loud as hell though.

I agree with you... I was also thinking about doing the exact same as you suggest. I dont know If I will ever need 100%. This car is already scary fast...

The important thing is weight. I notice a fair difference at the track from 3/4 of a tank to 1/4. I lost 2/10ths. If you do put in 100 octane, you should really have your tank almost empty and fill it to a 1/3 total so the overall octane is the highest and you have a good balance of weight to too low of gas line which is also not good.

Then follow the procedures above for raising the boost.

Just my two cents...

E90ice · 01-01-2008, 03:56 PM

Will do. Thanks for the help guys.

Anyone in the mood for a cookie?

turbotko · 01-02-2008, 10:20 AM

I wouldn't trust my engine to the additives. You just never know for sure what kind of octane you have in the tank. Mixing race gas and pump gas is much easier to calculate what you've actually got in the tank.

Definetely want to add the race gas then drive a short distance to be sure the pump gas that was in the fuel lines and fuel rail has been used up and replaced with the good stuff. Then bump the settings, and ideally drive hard for a couple more miles to allow a adaptation.

No, that is not true. Unleaded racing fuels are available up to 104 octane. Leaded racing fuel is what is bad for modern vehicles with catalysts and sensitive 02s...the lead causes issues with both. Stay away from leaded fuels in your 335.

incorrect statement. anything that not Unleaded race gas will damnage both cat and o2 sensor.

SO what kind of cars are you planning on meeting?
