....what do you think it will run post!! If figured why not ask opinions.
Here is the combo:
109 block .030 over with rjc girdle
diamond pistons
total seal rings
K-1 stock length rods
Eagle 3.4stroke crank
BHJ balancer and JW flywheel
224/224 billet solid roller/ .560/.560lift
GN-1 heads ported by Todd McKenzie
249cfm intake/ 219cfm exhaust
Stock intake manifold ported by same above
1.60 T&D roller rockers
Th400 trans with ATI brake
ATI 10" convertor 3800 stall
3.42 gears and moser axles
PT-70 .63 a/r 3in inlet
Precision FM
BGC headers with Tial 44mm gate
Custom built 3 1/2 dp and exhaust
-10 fuel line with aeromotive a1000 pump and accufab reg in sumped tank
MT ET streets 28x11.5x15

Thats about all i can think off right now. what do you think it will run? anything you would change and why? thanks, jeremy walters

Hmmm.
You left off two very important variables.

- What size injectors are you running?
- What ECM setup do you have? Stock ECM? FAST? Big Stuff 3? Translator?

I have seen your exact combo run anywhere from 10.90's to 9.90's. It all depends on the tune, how much boost you feel comfortable tuning for, how agressive you launch the car, weather conditions, track conditions etc etc. But I'll give two guesses based on stock ECM and aftermarket EMS.

With a stock ECM and 75-84# injectors, you should be able to tune the car to mid to high 10's 122-128 with decent launches and a minimum of 25psi total and launching the car like you stole it. Getting a chip perfected with either injector is going to be your biggest challange. I watched my good friend Laz for years perfect the factory ECM and Max Effort thumbwheel chip, but it took alot of testing and tuning.
With an aftermarket EMS like a FAST or Big Stuff 3 and either size injectors, you should be able to tune the car down even further to low 10's - high 9's 128-136. With the combination of highly superior processor and utilizing a true wide band O2 sensor with a 25% fuel correction factor capability during a run, either one of the systems listed will allow a far superior tuning capability vs the stock "chipped only" ECM.

One thing you need to be careful of, and I can speak from experience on this, is your selection of fuel pump. The aeromotive/SX/Paxton/Cartech designed pumps all have an inherent flaw. At high fuel pressure rates (like our V6 under 20-35psi of boost, roughly 65-80 psi of fuel pressure under WOT with base fp of 45psi line off) this pump starts to loose it's flow capacity. I ran into this problem on my old car running a Paxton pump which is identical to your a1000. It worked fine up to about 55psi of fuel pressure under WOT, but once pressure rose above 65psi the fuel pressure started to drop. The solution is a fuel pump that is specifically designed to be run at higher fuel pressure levels. Whenever I would spec a fuel pump for this very application (aka TSM style combo) I would always recommend a Weldon 2015A for cars up to 1000 fwhp. This pump has the capability of flowing 110 gph @ 80psi where as the aeromotive only goes up to about 60psi on the flow chart before it's gph start to drop off.
Your combo looks strong from this point, but there are a couple of other things that will directly affect your ET such as suspension components and spoolup. The PT70 turbo that you are going to run will support up to 850 fwhp pretty easily, however with the .63 A/R housing, it will limit your flow capabilities at higher rpms, especially with your solid roller cam and a good set of ported GN-1 heads. Why not pick up a .85 A/R housing if you already have enough converter to spool the turbo with the trans brake?
Anywho, sorry so long, drive it like you stole it and tune tune tune and it should be a very competitve combo with decent street manners. I personally know alot of good friends who have been down the road you are traveling now and all have worked really hard to get where they are today and had great results. (Shout out to Jason White! Congrats Jason.)
Hope this helps.

OOPS..... I forgot, I have a big stuff3 gen1 and 95lb injectors from racetronix. I plan on launching it as hard as the track will handle. Or until i break something.The pump is actually a Paxton. I just couldnt remember the number but i remember it being very close to an A1000..... thanks, jeremy

times in my sig. But if you want to launch real hard off the transbrake. I would get 28"x10.5" MT slicks. With good tuning and the right converter slippage, it can easily hit a high 9 sec time.

To quote a phrase, "You're golden!"
I agree with that ttypewhite just said too.
Just keep an eye on that pump. The larger injectors will help you and might even allow you to run lower than 45psi base fp but in all honesty running lower base fp and higher injector pulse widths is really a bandaide fix to the root problem.
Just my O2's worth.
