I was getting on the freeway and gunned it to about 100 MPH then the car shut down got off on the next exit and truned the car back on. Its started up but now it running very funny. it will gain speed but at about 3000-4000 RPMs it feels like something is holding it back like its not getting eoungh fuel. I have no idea what it could be.
Car has following mods:
stiegmeier stage 3 ported blower
2.9 upper / 4lbs lower
TB
bassani cat back
bassani catted x-pipe
KB boost-a-pump
CAI
SCT mass air
LFP heat exchanger
Does anybody know a good mechanic for these cars because i have no idea what the hell is wrong or does anybody know what could be wrong with it?

When they run hot, the rev limiter comes on around 3000rpm.

That has to suck! ![[Embarrassed]](redface.gif) Did You check it out or test drive it first? Do You know who You bought it off of, or just some stranger? How many miles on the car? I hope it's just a coil pack or something cheap like that. Good luck. ![[Eek!]](eek.gif) ![[patriot]](graemlins/patriot.gif)

Think it might be the clutch, car is shaking at idle and when the clutch is relased it starts to make a rattling noise.
anybody know of a good shop that can do this for me or have it looked at around the dublin area, willing to travel but not to much

Got free towing on your insurance?
Good mechanics are worth the drive. ![[Smile]](smile.gif)
From your description it doesn't sound good.
Compressin check time!
Was this car tuned correctly?
No 87 octane in it right? I mean, you didn't fill up at a 'one pump wonder' where there's 1 hose for 3 grades of fuel.....because the 3/4 ID fuel hose holds a few gallons of fuel & if the previous customer bought 87.....you got some 87 with your 91.

I would take it back to the dude you bought it from and ask him "WTF is up with this car!". If you can't get any satisfaction from him then I would swap the exhaust, maf, and pulleys back to stock, remove the boost-a-pump (if you can get a hold of the stock parts) and then take it to the dealer.
They shouldn't be able to tell if the blower is ported or not.
Good luck

FoxGT,
Give us a call. We probably have worked on more 03/04 Cobra's than any other shop around and know them very well. Just ask Rick (RixSikCobra) about the job we did diagnosing and fixing his problems.

I am not going to start a "flame" war with you on that statement... not worth my time.

I don't believe so because he was looking for a shop closer to HCI.

If you are willing to drive down to our shop, in Santa Clara, we would be more than willing to help you diagnose and fix your problem. If it is the clutch, we have a great solution.. our Apex Kevlar Clutch. We have installed a bunch of these clutches in 03/04 Cobras. You will be VERY happy with this clutch. Let us know is we can help you out.

Nope. Rick called a few time....we helped him diagnose the problem over the phone as best we could. Hopefully he'll get it taken care of.

A clutch failure would not shut off the motor at 100mph.
The vibration at idle is most likely not the clutch either. When a disc scatters there's very little weight that's out of balance compared to the 60+lbs of balanced rotating assembly. Typically an out-of-balance situation due to clutch is from a faulty pressure plate from the factory, in which case it would have been out of balance from the begining.
Could have wiped out the pilot bearing, but that's not likely either.
Mike, what is the surface of the 'Apex clutch' on both sides?
Kevlar, cintered iron, organic? Curious because we've pulled more then a few that have eaten up flywheels pretty good & not even been broken in yet (after thousands of miles). Bruce over at moderndriveline also sells those clutchs. He swears by them....& I know they handle power. The current trend in high HP clutches is for Cintered iron on the flywheel side & kevlar on the pressure plate side. Is that what these clutches have?
