think my car is running bad, but i beat a sc cobra

I just dont think my car is running just right, it doesnt feel as fast as when i first got the car. But it might be my imagination. My car wont even bark 2nd gear. I do have a badass mcleod clutch, that might be the reason it doesnt bark.

But anyways i raced a 96 cobra with a brand new cobra rebuilt motor. Forged internals and he said he ported either the intake or the exhaust ports, but not both. I dont know what kind of exhaust he had but i sounded pretty mean. Also the big thing was that he had a paxston supercharger. He said he was pushing 13lbs.

First race wasnt really a race, only one gear and it was close. But he was pulling me, with no juice. 2nd run i sprayed and we both went at the same time from top of 1st till about first of 4th i had him by about 1 car behind me. Last run i let him go first and then i went and we only went from 1st to bottom of 3rd and i was sucking him up very slowly, but we ran out of room.

I think my car is running good, but not near as good as it should be running. It is also idling at 500 most of the time.

Here is what i got--
95 m6 trans am
block bored to 355 with forged pistons
ported lt4 intake, and stock heads
lt4 hotcam kit
hooker headers
3.5" x-pipe
100 shot of the juice

ALso, i forgot to add that the guy in the mustang said he raced a corvette with a 125 shot and beat him pretty bad. He said it was a new vette too.

also his motor only had like 1000 miles on it.

And another thing, I raced a 99-03 gt with out my juice and he was at my back wheels from about top of 2nd to top of 4th. I dont know what he had, i know he had exhaust but i dont know what else. Hopefully alot, but probably a stock gt with exhaust.

Did it always idle that low ? Thats weird, could be the gauge tho, the RPM gauges are **** on these cars ... Does it sound the same at idle as it usaually did ? ... Take it to the track and see how you do with it there, then you'll know if your faster/slower then you should be ...

I know for a fact it is idling low, it sounds alot different than it did when i first got the car. Also i did take it to the track and i car a 9.5 in the 1/8 at 84mph, WITH JUICE!!!!!!!, but i had street tires and really couldnt hook up at all.

Please, only one TTT per 24 hour period... not per hour

Also, please keep it related to F-Body Tech! If people start answering your most recent question about how much hp a Mustang has, I'll have to move it to The Lounge.

Thanks!

As for lacking power ...

1- Faulty Distributor Cap / Wires / Plugs ... N2O Eats plugs occasionally
2- Dirty Air Filter
3- Spark Timing Controll system aint working rite ...
4- Brakes sticking ? This would be too obvious tho i guess ...
5- Clutch is slipping
6- Fuel Filter is clogged ? Impurities in ur gas ( Water ? )
7- EGR took a **** ...
8- Bad gas ? hehe sounds like a personal issue ...
9- Vacuum leak at Plenum / Intake Manifold

As for idling like anus ...

1- The Opti , again lol ...
2- Dirty Injectors
3- Low Fuel Pressure , should be between 41-47 psi with the key on , engine off , 3 to 10 PSI lower with the engine running ...
4- Vacuum Leak at manifold / plenum , or vacuum lines
5- Emissions system took a dive off the deep end ...

Dont rule out the simple stuff ... Plugs could definatly be it since your on juice , ive heard of alot of ppl who spray having to replace plugs alot more frequently ...
