Just as the thread title says, anyone have a before and after dyno from just an EWP?

I've heard so many mixed opinions on this one, I dont know where to start.

WS6.com shows an average gain of like 6HP, but that could be the difference from humidity from one day to the next. Also, the car could have been hotter/colder on each run.

My cousin, who is a mechanic, is under the opinion that you wouldnt see much gain at all, as it is putting a load on the alternator as well, and you loose reliability going to an EWP.

Then there are a few people on here claiming over 10RWHP from it.

I just wanted to see some of the results. I will be going to one eventually anyways because I want to go to a double roller sbc timing set on it one day.

 

I ran 13.3 w/o it, and 13.2 with it. Hope that helps.

 

There's a lot of variables to get that .1

 

Weather was more or less the same, as was my 60'. My tranny also slipped a little on the 13.2 run (hit the rev limiter), so HA! :P

 

Hey every little bit counts ...

I'm just as willing to hear track time results as I am dyno gains. I will be converting to EWP anyways, but just wanted to know if there was any real power gain to them or not.

thats a pretty good gain for the money. it doesnt just effect peak its a nice increase over all the rpms

 

Hey, a tenth is a tenth..I'm gonna try one along with a set of Kooks stepped LTs...Love to get 11.20s out of my set up looking stock....
