My Cobra Dyno Run

I made 240 HP and 281 Ft-Lbs of torque on my first ever dyno run. I ran out of go @ about 5000RPM. I think it's my car chemistry inserts in the exhaust that are the restriction. Only Time will tell.

Engine is a 5.0L, GT40p heads, 15511 CAM, FI

What is your overall opinion on the inserts?? Was the sound reduction good?? Did it change exhaust tone?? Were you running 2 or 3 disc? Any caps or packing??

3 disc. - no cap - no packing.

They work great at sound reduction. I gained 18 hp when I took the out later in the year. Right now I using lobak screw type mufflers and not inserts. I like the inserts + glasspacks better and will return to them in the future.

So when are you getting the supercharger?!

[Bobasaurusinsc]

I may go twin turbo instead. Thinking this Winter 2008

remember the lower the lift the less the chance of extreme detonation with twin turbos. It's a great way to make power, and it's the new fad! Very cool car! I was able to find a complete twin turbo kit for 800 bucks through ebay. The inserts shouldn't be a problem with such a low horsepower engine, especially cc's. They cause almost no restriction. If anything you might need a little more back pressure regulate that compression. Good luck and again awesome car!

Hey RB,

I pulled the CC inserts out and picked up 18hp and 17torque. I am still contemplating the supercharger vs. turbos. The car is so much fun to drive as it is it may be a while.

Need to find another dyno now that the big pulley is on the supercharger!

I have an 03 Mustang GT that has a bbk or-x and borla s-type mufflers.. It is unbearably raspy!!!! Previously i had factory exhaust with borla s-types and once i took the cats off it was horrible!!!!

You should get more RWHP with your combo. Some guys claim over 280 RWHP with ported GT40P's, intake, cam and exhaust. Good luck, and yeah.. what a beautiful car!
