So as most of you may know our Shop Evo dropped a valve about a year ago due to reasons some of you know
Link to story and with some of our free time we managed to rebuild it last winter but we had to start all over again with a new head since the old head was trashed. We have had a VERY busy summer here at CarZ and did not have much time to work on our Evo because we were busy working on customers cars. Well it is that time of year when it slows down a bit and we decided to bolt on a freshly ported head by MADCAP and hook up the nitrous to see what we could get.
Our old numbers with a DPR ported head was 546awhp & 430tq @ 28psi. With the stock head (un-ported) we managed to get roughly 560awhp & 450tq @ 28psi. After a long summer of fighting ignition problems we gained another 20hp with the new ignition setup (Buschur COP). After getting the EPIC EVO tuned the other day we decided to strap our Evo to the dyno today and made 639awhp & 501tq @ 29psi on boost alone. After re-wiring the nitrous system to my likings we decided to make a few nitrous pulls with the highest numbers netting 810awhp & 661tq @ 28psi. This is a new record for the highest horsepower car ever to dyno @ CarZ Performance. As most of you know this is NOT a high reading dyno but as we like to say a more "accurate" dyno. There have been some mean Supra's, Nova's, Vipers and even Dodge Cummins on our load bearing dyno that were very close but none over 800hp. That certain Dodge Cummins still holds the torque record for 1660tq though which is normal for diesels to have almost double torque than horsepower.
Here is a dyno chart for you to view, keep in mind we are not done yet. I am sure there is some more hidden power in this Evo and we will manage to extract it soon.
