S3's timing and race gas

se-r pastor · 11-04-2002, 05:09 PM

I know that S3's don't like timing above 15, but what about advancing the timing when using 110 octane gas. Will the cams show any gains? Just curious

Uncharted territory. Try it with some VP C12 on a chassis dyno and let us know. Sounds a bit silly to me, though, unless you can also tweak the fuel curve.

If you run race gas, install a test pipe. Race gas is leaded, the spent gasses will clog your cat.

...not to mention foul your O2 sensor.

I've run Torco fuel 114 I think on the dyno with my C2's and timing set at 25*. Didn't do anything really.

How much horsepower does your car make with the C2s?

I don't know if its worth it in your situation, my friend keeps a spare 02 for when he goes to the track and runs race gas

well, my car did not dyno very well. With the only mod being JWTECU and the C2's it put out 132whp. I figure the C series really need a GOOD header and exhaust to really flow. Everyone else dynoed very low as well. On this setup the car traps 93mph so thats a good indicator the dyno was off

CowboyDren · 11-21-2002, 07:19 PM

What?!?! Are you trying to cheat in an autocrossing class? What would possess you to run any aftermarket cam with a stock exhaust manifold and tubing? If you don't have a header and a 2.5" pipe kit, you're trying to make your engine breathe through a Swizzle Stick, and that's just wrong.

97SE-R C2 · 11-21-2002, 08:16 PM

Yeah it's just wrong because I took off the AEBS 1 piece/Courtesy Exhaust/unothordox pullies/PR CAI Just so I could bolt on this stupid T-28

Dude I'm not retarded. I already stated the cams need everything else to function. The car dynoed 138WHP w/o the cams or header.

CowboyDren · 11-21-2002, 09:03 PM

Sorry, but this is the all-motor forum. And there are people who don't know that cams aren't the first mod to make and do have the money to get JWT's C-series valvetrain.

97SE-R C2 · 11-21-2002, 09:17 PM

You must have missed my sarcasm

I know you didn't know what all was done before the cams were installed. The cams are now out and the car is very slow unitl next spring. Sorry for the confusion.

I know this is old BUT in the latest issue of Turbo they say that Conoco sells Turbo Blue Unleaded 100 octane. That should not mess with your O2 sensor at all. Only the leaded race gas.
