I haven’t seen any data on this issue so I thought I would pose it to the group. I was wondering if anyone has any dyno figures (preferably AWHP) on an Evo VIII equipped with the Ultimate Racing Stage One Plus Kit and the HKS SS BOV. Their website does not reference any dyno figures, only ¼ mile times, but I’m sure someone on here has this kit installed and I would like to know how it performs out of the box.

In case anyone is wondering, here are the vitals for the kit:

- Ultimate Racing 3" Stainless Steel Turbo-Back Exhaust System
- Ultimate Racing Pre-Programmed HKS Super AFR
- Ultimate Racing Pre-Set Turbo Smart Manual Boost Controller
- K&N High-Flow Panel Filter
- HKS Super Sequential Blow Off Valve VTA

 

I had this setup a while back when I first got the Evo. My car was putting out around 303whp (AWD) at the time. I ran 12.4 at 109.8MPH on this setup, on 20psi of boost. I did run their test pipe (not the high flow cat).

Later on, I swapped out for a Greddy e Manage and got 335whp out of the car, and it ran 12.2 at 113.89mph, on race gas.

 

I''m running the ur's Stage 1 Plus upgrade but upgraded to the Greddy E-Manage. Car feels great! No dyno numbers yet though, but soon!
