01 Cobra Engine Boosted

[JohnEagle]

I have a stock 01 Cobra engine with 03 supercharger set up. What are the motors limits?

01 Cobra Engine w/6 Bolt Crank
03 Ported Supercharger w/Complete 03 fuel system set up
Stock Lower Crank
2.93 Upper Pulley
Kenne Bell BAP
3:73 Gear
Stock Manifolds - No cats - Flowmaster Exhaust

Those are the basics and right now I am sitting on 486HP w/ 450 Tq.
How much more can I go before I bend a rod or something else gives? I want to toss on a 2.76 upper and have it retuned. Yes or No?

Thanks
John

Honestly, you're already past what I'd be comfortable with on the stock '01 rods/pistons. As far as limits go, pulley down and let us know what breaks first.

 

[KLeech]

Yeah you're already past whats considered the "safe" limit, usually after 450 things start breaking.

Such a hard question to answer as there are so many variables, but I think youre much closer to the engine going poof than I'd want to be.

Mine popped when it leaned out with a vortech and roughly same numbers. Forged now! I think 450rwhp is generally considered riding the fence...

Was your short block rebuilt at one time? Cobras had an 8 bolt forged crank. GTs and automatic Mach Ones had a cast 6 bolt crank.

Yeah, I too was wondering about the 6 bolt crank. Definitely not right for a Cobra....

Yeah my tuner is really not wanting to turn it up anymore. I think he actually made 500 hp but turned it down a notch and lowered the rev limiter. So far the car has done pretty good. I have made about 20 plus 1/8 mile runs and it's stayed together.

There is a long story behind the car. It's actually an 03 Cobra... or was at one time and I found out the hard way that it doesn't have the correct engine in it.

Thanks for all of the input.

I would actually be curious to hear this story...or at least the cliff notes of it.

Yep that's the short story. The car was sold to me as factory unmolested. Not even close. Anyways I ran a camera down the spark plug holes and it concave pistons not flat tops and I ran the camera through the bottom of the engine through the rear main plate and it has the skinny ford rods.
The transmission needs rebuilding as it shifts crappy and is noisy as heck.
I just had the gear put in along with everything else in there because the spider gears were shot and the cover was cracked. Thanks to my friends at RPM of Georgia the car is running and driving as well as it can in its current condition.

Op that's bs I would make the dealer make it right even if They didn't Know you still got scamed. It's Not right they're still at fault in my book.

Yeah well I didn't find out about the engine until after I had the car for a couple of years and went to install a clutch and flywheel and the flywheel did fit lol. Too late then. I am lucky like that.

This brings up a question. I have an 01 cobra and the only mods I have are gears, Bassani cat back, and Bassani Catted H Pipe. Would I be safe to throw on a Supercharger on it as is or am I asking for trouble not doing something else first to help the engine handle the additional horsepower.

this is a daily driver right now by the way with 76k on the car.

Depends on boost level. 8 psi or 450 rwhp are the most quoted numbers. Would need new injectors and fuel pump.

Many thread in here about 99/01 Cobras going to forced induction
