2 pulls
-769.2hp
-924.5 tq
on 26psi running out of fuel at 4600rpm

-813.2hp
-846.3tq
on 23psi

661.5hp
688.5tq
at our elevation ~1mile high

Car has 2 t3/t4 57mm turbos, 42lbs injectors (420cc injectors), intercooled, stock displacement (better pistons and rods, barely ported heads) Still a 2 valve, and stock cams. It also has stock cams and a stock tranny. It's gone 11.20 @128 with 140hp less, at this elevation.

...so basically a 12k car with 5k in mods, with 800+hp, and will run in the 10's at sea level.


...the guys that built the car are the same ones I was talking about that are going to start making kits for our cars.

Very impressive. Are you sure about the injector size, that's WAY small. No wonder it ran out of fuel, but I don't think you could even make a full pull with those at that power level.

Sounds like a very cool project.

very sure on the injector size. It's out of injector and pump...

Reason I asked is because he was so far off. He'll need a minimum of 65's if he doesn't make any more power, and I'd go 75's for some more safety factor and room to grow. Of course he also needs a pump capable of supporting that much supercharged power.

They are going to put in 60's. These guys know their stuff, so I'm not too worried.

I always err on the larger side as there's no disadvantage to do so. The injectors are the same price, it can be tuned just as well, and will support more power. The 60's will support your 800 HP at about a 90% duty cycle which is as high as I would go (factoring in a .55 bsfc). At altitude they're plenty.

Good luck and have fun!

Jody, I was thinking the same thing. I have 56s for decent coverage to 500hp (my target).

Link doesn't work for you because you are a Jackass...

Save as, then open with windows media viewer...

It's a street car, so it'll be at about 600hp most of the time, which is why they figure the not-as-big injectors. But otherwise I agree with you guys, but their logic makes sense.
