Orbell, you need an intervention!!!

nice setup. What specific A28's are you running? 2868/2871/2873?

Mine are sitting in my garage waiting for me having time to wrench - which will happen tomorrow.

I never imagined that the Alpha 28's were going to be capable of making this kind of power, I believe this sets a new record for Alpha 28's. Last I checked this power level is 3076 territory. That being said, I have bottom of the barrel fueling cause that's all that was needed to make 700whp on Alpha 28's, which was the limit all tuners have put on these turbos. But don't worry, I do have a complete fuel system sitting in the garage which is going support 1,200whp

The dip I believe is mainly from wheel spin, however the lean line is cause of fueling...

I appreciate you envying my 996tt... stay tuned for more result.

I dont understand why these you have on dip, do they flow that much more ? is the head built or and matched for their flow? i know if you dont have the built head with the big valves etc it can actually hurt power.

as for the fuel system, im running the same inline and i know it runs out of fuel up top on my setup , but i dont chance it . just a matter for few weeks till its corn fed and new system aswell.

i will envy your car when you show me 1000+whp

Todd actually likes using the 996GT3 manifold instead, however thats another $3,500+... I do have head work done for better flow... I am going to drop my 1150cc injectors and walbro 450 in for now and see how the afr's react.

Congrats on your new to be setup, what kind of turbos you using...
