I think you mean a master power 70mm turbo.

Here's the thing, the power you can expect depends on tune, the amount of boost, and the times will depend on chassis setup (i.e. how well the car sticks). And, what you'll see on a dyno may not give you a good idea of how your car will perform. That's because you have a stalled auto. Typically stalls significantly lower the amount of power measured by the dyno, but when you take them out to the track, they still go like hell.

Anyway, your block is good to around 500rwhp on a good tune before you risk splitting it. With a 70mm turbo, you're not going to have any problem making those kind of numbers, if you want too. That turbo is good to a little over 700hp. I'm not sure a 255lph pump is capable of moving that kind of fuel, and I think you'll probably need to replace the fuel lines, too. The injectors look good, and the rest of the components will help make the power you want to at relatively low boost. Anyway, you'll have enough motor to run it into the 9s if you get the rest of the car figured out.

Do you have a way to tune the car? I have the TWEECER RT but, most guys say the Qt Horse is a cheaper way to go & can do every thing the TWEECER RT can. Im no expert on this stuff but my import buddy made nearly 600 AWD HP at the dyno on a 255 pump at 25 PSI boost. A speed shop back home told me that stock fule lines can flow enough fuel to feed about 550 HP. Thats about all a stock block can handle from what I have read. Im going to be using methanol injection to cool the air intake charge & supliment my fuel needs. Thats something you might want to look into also. Check out Snow Performance for that. Good luck with your build and like FastDriver said. You have to get traction to use all that power. Check out BaseLine Suspension for a good read about how to launch a drag car & suspension geometry.

You'll be able to make more power than that block will handle. I wouldnt go over 450whp with an auto. That will still be on the edge, you just never know. It's all in the tune. Just stay conservative
