Thread: Can You Estimate My 1/4 now?

Well its tough to say, first you don't have the mods to run a 3.25 pulley. You need either an IC, a cam, or rockers on pump gas to run knock free, plus I don't see either a Plog or some type of header to help with the exhaust flow. Which brings us too have you done any tuning to the car, or is the pcm, have the tune you were sent? That being said if you had a perfect tune running Knock free. I say 13.8-13.9.

I understand what you are trying to do, but saying it will get rid of knock, and what your operating at right now are totally different things. The 3.25 pulley with the mods you have right now is a good way to blow your engine up. It is possible that you might have no Knock with a 3.4 pulley on there, but I doubt it. The upgraded pcm is a good start, but thats all it is, a good start. Every car reacts diferent to modifications. The initial tuning in your pcm is programmed for the masses not the individual. You need to get with a local club, and see if anyone has a tuner that can assist you. They can use that to plug in, scan the car, and see how it is reacting to the current mods you have, read the knock, and make adjustments as necessary to rectify that. My .02 though is to take off the 3.25 pulley, put on a 3.4, get some headers, and start tuning for that. Once you get it tuned for the 3.4, add your kit, retune on the 3.4. Then depending on knock, timing, trims, etc etc. Look at the 3.25.
