Anticipation...

My car has been built previously by another shop that did not hook up the knock amp properly. It was not hooked up to adjust timing, only to read the knock. So, Sam is a little nervous I think based on how it ran when he got it and a lot of other mickey mouse stuff that had gone on. My sense is he is not confident in the motor and doesn't want me to be disappointed if/when it goes (again). He said to me that his tune was about as conservative as possible. This build should be over 600 no doubt.
I don't have double pumps but they are not necessary for a little over 600. With HKS 1000cc LI injectors there is plenty of room for fuel. Seems to me the concern of the motor itself. I'll let Sam comment on that further.
BTW, I do have about $2,600 worth of work on my stock heads in parts and labor. Bench test showed that they flowed better than many of the Cosworth heads he had tested. Who knows though right?

Not sure really. Although, low boost (A) was set at 11psi and high boost (B) was set at 14psi when I received the vehicle so I can only assume that these were the settings during the pulls.

With what I have been through, I am just happy the car is running great (thanks to Sam) after four years of BS, one stock motor and one blown built motor!

Dude, first is useless, second is totally out of control and third is barely controllable at 15.4psi. Why in the world would you want 670+rwtq? That's not even streetable with any kind of pressure on the gas.

wait, why is Sam nervous? Isnt this an entirely new built motor and heads from GTM?

As far as your gears being useless you need a 3.3FD rear end and a real set of tires.

ahh ok, I was thinking when you said GTM was making a build thread, that they actually built the car. I'd be over cautious for sure as well in that case. To bad GTM didnt tear down the motor and inspect it.

I think he is saying several guys have put down more power than that for alot less money. For as you say "a serious build" with $30-35K in just parts and EMS people might have been expecting a little more

Anyone in my position with my build can turn up the boost and let it rock, race gas, whatever. Dynoqueen is not my thing. Sorry to disappoint you but that is not what I am in this for. I want to get back on the course with something that can kick a$$ and won't give me a hard time.

most people i see are into the 500's by 14 psi.
it could be my factory heads and valvetrain restricting flow,
but as you can see jtgli is making 585whp at 13 psi on stock heads ( dynapack though)
The only part of the map that i am not familiar with tuning is the cam timing, and it is from hal's base map, which is the only thing i could see making a difference.
afr's also.. under boost my wideband and the dynojet wideband do not agree, mine being about 1 afr richer (low 10's) which if that's the case could be taking some power but not a very large amount. Some more tuning and different dynos and we'll see. I go to the track sunday after next if weather is good, so my trap speed will be a good indicator.

i know... timing isn't too conservative and boost is high.
