If you guys want a Vortech kit, let me know!

 

Ok, so I still haven't seen a dyno of a stock revup vortech out of the box. Anyone?

 

I would say its around 330rwhp but yes most people that dyno tune it so dont have the graphs

 

I would agree...I have seen as low as 298whp on a Vortech kit out of the box...but I think that was a 287 motor.

 

dam i would be pissed if i got only 298 at the wheels a modded sti with a few mods would beat me lol that would suck

 

298 is completely stupid, obviously not tuned or the tuner doesn't know what they're doing - and/or their dyno reads really low. But there's no reason 320-340 whp shouldn't be possible on an otherwise bone stock car with the earlier 287hp engine if tuned properly

 

^Pretty much right on the button. 313whp at 5psi here on the 287. 5AT.

 

Well hopefully if i got time i will dyno my car with stock tune and show you guys where I am at...When i first got the kit i logged my afr and it was pig rich at 10flat...Now with how i stand i am running 11.5 to high 11s and mind you this is with my bolt on mods below...

Stock 3.33 pulley
Headers
Test Pipes,
JIC 3in, single exhaust
Motorydyne 5/16 spacer


I have the 3.12 pulley in hand and I am going to install once i buy my walbro 255 pump...

 

This is an old thread but an answer that is not commonly answered. Here is my stock Vortech setup Full Kit :



My mods include a 5/16" spacer, non-revup lower plenum, nismo headers, nismo exhaust and that's it.

 

Nice. Are you tuned? Your AFR seems really low between 75~90 mph... and really high at 110 mph.

 

EDIT: gonna have fastlane inc. tune it here in Houston tomorrow. no reason to drive an untuned car.

The sniffer seems really inaccurate that they use at the dyno.

My PLX Wideband showed anywhere between 10.4-11.2 when I watched it the entire time.
