Hey Cal the fuel pump is still new in the box and could be returned, what pump would you recommend plus remember I would like room to grow.
Ya.. but the TTA heads have "issues" when you start to really turn up the steam. There is a wall in that lower 10 second range.. as long as you keep the performance slower than that, you wont need a better head and you wont need a better fuel pump.
Been there.. done it.. know a few that have been there and done it as well. Same results. Maybe maybe you can be the fortunate one to figure it out. I know where the wall was for me.. and its been the same for everyone else. 135 MPH. Discussion with Jack Merkel was the exhuast runners where too short on the TTA head. Could also be downpipe design that has a sharp bend creating too much back pressure. Either way, whether its the heads, DP, headers, etc.. keep a very close eye on the tuneup if you choose to venture up in power.
If I had to do it again, and wanted to go lower 10's or faster.. I would have a really good look at the AC and downpipe issue using the GN1's. But I wouldnt do it with the TTA heads. Just my humble opinion, and trying to save you some wrench turning.
The motor looks absolutely beautiful. And your selection of parts has been perfect.
Good luck with it.. really. And remember "your saying" .. "I would like room to grow" With the TTA head.. I know what size room you'll have

HAHAHA there has never been truer words spoken! I to agree with Julio. I am at the wall as well with TTA heads :frown:. Just dont ask for to much and have fun with the car; that should keep you from taking the heads on and off-on and off-on and off.

I have been thinking. How do the exhaust runners have anything to due with the TTA heads being a limiting factor? Would like to know his reasoning beind that.

You like that?
I can't beleive all the people that are actually critisizing this car. The comment "too racey"???(from the TGO web site) That is crazy. This car is absolutely beautiful and exactly what I'd do if I had more money. I won't change a thing - the car looks awsome!
One pic we haven't seen yet is the interior. I've always wanted to do a roll bar with a tan leather padding and keep everything else looking stock.

Its about airflow and the short runner stalls. backpressure tests on the exhuast would be a great place to start.
Mike Shields aka Jicaju runs a stage motor with TTA heads. Same problem.
