Re: Finally got pics of my 88TC

Steve Choma's TC has basically the same combo and he makes 335rwhp with 25psi. He has also has a lightly ported stock valved head and a stock bottom end. The fresh bottom end and big valve head on Nick's would make a big difference in flow. If properly tuned I could easily see 300+ with 18psi. Especially if he has a bigger hybrid turbo.
If you do the math with my best quarter mile mph 102.5 and the race weight of 3552 it equates to about 300rwhp and that was with only 16 psi. The tune was terrible and since that run we found out the valve train geometry is way off. In fact the rockers were cutting into the retainers and when we pulled the head off 3 of the 4 intake valves didn't completely close. I can't wait to get it on the dyno once it's fixed.
I'm looking for around 370+rwhp and hope the T5 lasts till next year. The Tremec isn't on the upgrade list till spring 06.
