Thanks to Simon for overnighting a pulley set I was able to get it installed today! I also appreciate the fact I could talk directly with someone who's been there and done that...

First impressions: Install time was a little less than 2 hours. Straightforward and simple (with the right tools)...
Tip: the idler pulley doesn't need to be removed - just lossen enough to slip the belt underneath.

Second impression: Dyno time. The shop was a little skeptical and hoped for at least a 5 rwhp improvement....well, needless to say they were impressed (as was I) with the results. My dyno runs almost mirror those posted on Evosport's web site. My car has the charcoal filters removed and sections 1 & 2 installed with stock mufflers out back.

Third impression: Driving -- the change is definitely noticeable. The car is quicker....wheel spin galore. The torque really kicks in at 4K rpm and doesn't relent until redline. You'll notice on the dyno chart how linear the torque is.....

This is the best bang for the buck since removing the charcoal filters!

Good news!!

Wow. That's very good to see that the gains are present on back to back dyno runs. Unfortunately, I could not get my car on the dyno because my local shop cannot prevent the electronics from shutting everything down when trying to dyno. How were you able to get the dyno runs? I'd really like to put my car on the dyno and see how much power it's making now. You can PM if you'd like.

As far as seat of the pants difference, I did not have the same results. I don't know why, but I do not feel this huge gain that is being shown on the dyno.ouich

I don't know if it's just me, my computer or poor scan of the graph, but I can't make out the graph too well.hmmm

I see the graph tracing but can't read the before and after numbers. Can someone read them to me?

Where are you guys getting the impression that these were back-to-back
runs? Maybe I'm reading it wrong but it looks like one run was made
4/29/06 @ 12:49:28 PM and the second was 3/6/07 @ 1:35:02 PM

:dunno:

Were the sections 1 and 2 installed for the first dyn run? In other words, what modifications were added between the first and second run, just the pulleys or also the exhaust? And what about the filters?

If you expand the picture, it becomes very clear

Great catch!

That makes MRichmond's questions very important.
