Got my car dynoed today..284 rwhp 308lb torque..does that sound wrong? i was pissed when i heard thats all i have..seemed to peak at 5800 rpm..do these seem like right numbers to ne one else?

 

Auto or 6 speed? Dynojet or Mustang dyno? SAE, STD...corrected? Don't get hung up on dyno numbers...get some track times.

 

6 speed,dynojet

 

I would bet you would pick up a decent amount from a cutout, because the flowmaster systems are known for not flowing as well as other systems out there.

 

What was the air/fuel on it? Yeah, get rid of the chokemaster exhaust...I picked up 10 rwhp with a cutout on stock manifolds...should be worth more with headers.

 

The HP number is not too far off, maybe 5 rwhp low, but the tq seems about 10-15 rwtq too low. The flowmaster is probably holding you back. Like others said, what was your a/f? What hp/tq did you think you should get?

Take the Flowcrappers off

 

Best run: 80.8°F, 29.92-0.67 in Hg, CF=1.00, RPM/MPH=51, MAX power = 285.8, MAX torque=308.3

 

chris left the dyno sheet in my car so i posted them..

 

I can see 15hp from taking off the flowmaster.

 

taking them off and putting somethin else on? or what about a cutout?

 

Either one, preferably both

 

What should my numbers be with all my mods?

 

There is no number they *should* be. All cars are different, and all dynos are different.

 

Actually, that's pretty good for the mods you have.

LT-1's usually dyno around 250-260rwhp stock, so you're doing well with 284, probably due to the long tubes.

You don't have any significant mods (besides the headers) that change the engine characteristics. You just have bolt-on stuff (besides the gears, which don't add HP)
