Dyno numbers

[X vetter]

A couple of months ago I had my GTS on the dyno with just smooth tubes & filters and the rear muffler delete...403 hp & 443 tq with the a/f way rich.

Now I have a complete Random tech 3" exhaust w/high flow cats (no headers) and
its going back on the dyno tonight...

Any predictions ??

I would guess you will gain around 15-20hp and tq.

Either way keep us posted.

Prediction: 424HP

415/455 would be my guess.

'99 might get you 418/451! Make sure you run her hard before the dyno. Got to clean it out a bit!! :thumb:

 

[99 R/T 10]

432/465

Update

After only 2 pulls (this was a Mustang club dyno night)
it registered 396 hp & 447 tq...

Last time I did 3 pulls and there was 9-13 hp/tq increases
on eash run so this may not be completely accurate...

No a/f measurements but I suspect a rich condition...

Any ideas or suggestions welcome

Any ideas or suggestions welcome

Get another exhaust system...

Get on a dyno with an A/F. Most of the guesses were based on a Dynojet, not the mustang. The Mustang reads lower, but gettting a dyno pull without the A/F is useless.
