231.9WHP with new big valve head. Stock cam and ECU.
Attachment 18924Yes, the numbers are real (see attachment)
231.9WHP and 184FTLb
Before the head I was at 193.1WHP and a peak of 172FTLB but it fell off quick. The dyno was done a week apart. the outside temp was only 3 degrees different between days. No water, no spacial fan, no ice just the same car before and then after adding the head.
All this from my new "Big Valve" head with a stock cam and the stock ECU. My Tuner el spent allot of money and time to develop this head. I was amazed at how well the car performs with the stock ECU. The car runs better now then when the stock head was on. Tommarow we are putting in the new custom ground cam with adjustable cam gear. Next week the custom header and 3" exhaust go's in. The final item of this "5 piece system" will be the custom ECU tune. We will dyno the car after each install along the way to document the numbers. All on the same dyno
I have read allot that big valve heads will kill low end TQ. Well, take a look at my dyno numbers. You can throw that idea in the trash. The TQ starts immediately and stays flat across the board. The car pulls unreal!!!! I can't wait until the rest of the system gets put on.
Longboard

You are absolutely correct. I stared at the screen in disbelief then we all laughed amazement.
This head breaks new ground. The drive-ability with the stock ECU has me scratching my head. The car loves all the new air.

I can not give the specifics of the head at this time. Mine was the first but it's not just the valves.

I will be at AMVIV for any one who wants to see and get a ride.
The car will be allot stronger by then. The rest of the items should add a ton.

great numbers. I have just about the same upgrades with larger valve head and larger shrick cam. The car pulls very strong. The front end just pulls extreemly hard and at red lines it kind of wiggles due to too much pull and speed.
I haven't done a dyno on mine but the shop that has done all my upgrades are telling me that I am defenitely getting around 230s whp.
Keep us informed and don't stop modding.
