00 GTS Dyno and TNT Headers

[Mark Red GTS Cooper]

Took my car to a dyno in Woodbridge VA yesterday, and I really have to say thanks to Roy over at TNT for building a great set of Headers and full exhaust.

I am running smooth tubes, filters and the merge style TNT headers, high flow cats, and no mufflers,

First run, MaxPower 436.1 Torque 481.5

Second run, Max Power 436.0 Torque 482.2

Third run, Max Power 446.0 Torque 489.0

Next are T&D rockers, and re-dyno.

If anyone wants to see the dyno slips let me know, I will be happy to e-mail them

Do you have a pre-modification dyno? My 97 GTS with smooth tubes and K&N's put out 422/457 SAE. 22 HP and 32 ft-lb. more sounds pretty good with the headers. Did you replace the cat back pipes with 3" or are those still sock diameter?

My 2000 GTS dyno'ed at 436.1 rwhp and 483.1 ft lbs - with just tubes and filters (SAE corrected) at 10,000 miles. Of course, that same monster engine is now in Detroit undergoing a "refresh" after burning oil at the rate of 1 quart every 350 miles.

Sure hope it comes back as strong as it left! Of course, I won't find out until after another 1,000 break-in miles. Sigh...
