1995 Cobra.
Stock block/internals.
Heads/cam/intake
Supercharger w/ 8psi and powerpipe that claims additional 2-3psi of boost.
Recently replaced the 24lbs injectors and MAF which was calibrated for 19lbs injectors. The car was tuned once (horribly I might add) with that set up.
I have just put in 42lbs injectors, a PMAS 42lbs MAF, and a aeromotive fuel regulator.
Car was running like sh1t but It has slowly been getting better and better after electronic adjustments, sparkplugs, and so on.
Just adjusted all electronics perfectly (IAC included). Car is running like a bat out of hell; running down my best friends modded 04' terminator. With sticky 275 yokohamas, my car will still lose traction at 65mph once I hit 4000RPM.
Has obvious signs of needing to be tuned (struggles to find idle, hesitation, burning rich, etc), before I do so though I still have a issue - believe it is a vaccum leak. During avereage driving, the car will begin to sputter badly, and almost all of the time it does this, it will shut down, and will continue sputtering, shutting down, till I limp my way home. (This happens maybe once a week and after letting the car sit for a bit the problem stops). Im confident this is a vaccumm leak but puzzled because it happens so rare and I would think it would do this constantly if it was a leak. Fuel pump? (Has a t-rex pump), ignition? (has full msd set up with ditributor, blaster, boost retard, etc). Also, While searching for the leak I took off the upper intake manifold and found oil...a puddle of it gathered up. Only thing I can think of is loads of blow by coupled with extremely light royal purple motor oil (should have just used some mobile1 i know). The engine is the orginal block/internals and only has 39k miles - of which 6k have been with the current modifications. I know supercharging and everything decreases the motors life but I was pridicting reacing 90k or more miles before upgradding to a DSS 331. Ideas?
This car is my daily driver and I want to hurry and get rid of these petty issues so I can have it tuned and running proper.
