hate to bring it up again, but my mods have changed slightly. Just want to get a whp estimate please from the people who know what they are talking about.

Mods:

Trifecta/HP Combo Tune 24psi, no spikes above 25psi
AEM Cold Air intake (new version)
ZZP Upper Charge Pipe
AIS Meth Kit, Steel Lines, 100% Meth, tune adjusted for proper timing (plus 94 octane gas)
ZZP Magnaflow Catted Downpipe
Muffler Delete

350whp?
388wtq?


Thanks.

 

345hp 390tq on a dyno jet

U should go catless

 

Who tuned it and what kind of timing you running?

 

take it to a dyno

 

With the Meth kit I'd say 355WHP/390WTQ (Dynojet) but this is just a guess take it on a dyno and find out.

 

ima say 335/385 cuz its a trifecta tune

 

I'm gonna say 320whp and 365whp. A guy around here has full bolt on minus the intercooler with a trifecta 24psi tune and he only hit 275whp and 325wtq on a dynojet.

 

The OP is running meth WITH a 24psi tune man. He should def be around 335-345whp at least. Something is def wrong with that guys numbers you mentioned. Im on a 24psi tune with full bolt-ons and I dyno 325whp. Shoot, I dynod 295whp on my 20psi tune last year.

This is all speculation OP until you DYNO. Doooo iiit

 

330/355

 

Thats my car that he's talking about, and yea back in October I did a pull, and it hit 325 WTQ which seems to be pretty accurate, but the WHP was only 275 as mentioned, which didn't make much sense to me. Don't know whats going on, because as mentioned i'm fully bolted minus intercooler and 24PSI Trifecta.... I thought i'd atleast be 300WHP. Have to see in the spring again.. Maybe I'm doing something wrong on the dyno? Haha..

 

Different dynos read differently. Maybe the one you used was out of calibration. Look at your graph, was it STD or SAE? STD is usually a little higher. To compare with other results from other dynos, you should use SAE. Temp, altitude, humidity all affect the dyno reading. Don't get hung up on dyno numbers, the dyno is just a tuning tool.

 

i did 336hp and 375tq

 

That exact thing happened to me. Turns out the dyno wasnt load bearing, although it was advertised as such. It had the capability for it but the owner didnt buy the brake kit for the dyno to simulate road load. So the turbo doesnt get loaded fully and the dyno spits out those funky numbers.

 

1002/1435.

 

Thanks for the input.

336hp without meth, I might get 350 then.
It's not just a trifecta tune, it's a combo tune.

Could of gone catless, but felt is was too loud with muffler delete.
Plus, have seen guys with cats not having much of a hp difference at all.

 

I hit 271whp and 297wtq with gms1, turbo back and Kn intake. My car is laggy tho, to which I suspect a boost leak. Will find out in the spring.

 

whose your tune? I had just a byt tune, intake and catless dp and i put down 310 /361. Again only with intake and downpipe and byt tune. Trifecta is nice, but is not always the best tune, they seemed to be a "custom" canned tune.
