Throwing it on a Dyno this weekend.. Any guesses hp/tq???

 

It would probably help if you told us what you've done to the truck. Everything makes a difference. Even wheels and tire sizes.

 

^x2

 

Haha sorry it has true dual flowmaster exhaust, air aid CAI and a 93 perf 5 star tune running stock 20s at sea level ...

I'm doing a before and after the roush supercharger

 

345 hp at the wheels before and 460 hp at the wheels after.

 

Post HP and torque numbers when you get it done. Sure probably mid to high 300s.

 

330 RWHP before, 440 RWHP after

 

So it was 377hp/412 tq

 

Before?

 

Yes before I get the roush installed this week and post the after results

 

Pretty decent numbers so far. Good luck

 

Those are pretty sweet before numbers! I so wish I would've seen this thread last night... My guess would've been dang close... LOL! Gives me a good idea of what kind of numbers I'd make with exhaust work. Also backs up my numbers pretty well so that I definitely know the dyno I went to is dead on. Subscribed now and can't wait to see your after results.

 

Exhaust work downstream from the cats = bupkis fer performance gains. Zip. Zilch. Nada. Caveat - Fartmaster crap MAY actually show a DECREASE on the dyno.

Long tube headers will show tangible increases. Hi flow cats, meh.... Maybe a couple ticks. However, changes to the exhaust from the cats back only really net a change in sound.

That Roush charger, however... Now THAT'S a different story!

 

Ya I am changing the flowmaster for roush once I get around to it .. But I like the sound of super 40s over my old magnapacks anyday.. But that's just IMO

 

Dyno seems generous.
