bought RJC front mount. what gains over stock?

[GNJesse]

i bought the new RJC front mount so im just waiting for it to come. i have been running the stock intercooler for a while. i have ported heads, bigger cam, intake, injecotrs, stall etc. all the parts are there except for the front mount. what kind of gains should i see?

Thanks, Jesse

Depending upon your weight you should be able to run some mid 10's on full kill.

What does your car run now and MPH?

i had it to the track once but the car had some problems. with a trans slipping into third, bad o2 sensor (ran a few to many tanks of 110 gas in it), and spinning for about 50 feet. it ran a 12.1 at 115 MPH. thats on the stock intercooler. it was at 25 pounds of boost but i dont think it mattered cause of the blown 02 sensor.

What are you running for fuel management? I hope a wideband stand alone, or at least have a wideband datalogger like an LM1. That thing must have been pig rich on the 115mph run if it had the 83's in it. My guess would be 10.85@124mph weighing 3600lbs if you can get a good 60' and get the tune right. You need an accurate way of measuring air fuel ratios or you will break it. If you are referring to the stock O2 sensor in your post, it has no effect on WOT air fuel ratios.

You will see huge gains! My stock was causing all kinds of problems. Took for ever to spool! Bad knock, just way to small! I do not have the RJC FMIC, but anything with mods will do better without the stock intercooler!
