here are some pics, results were 434RWHP at 7.5 psi on our Mustang dyno, so about 475-480RWHP on a dynojet

have you posted a dyno chart? I am currious as to torque, specifically low rpm torque. Looking to compare it to a s/c.
thanks

I will post up the dyno later when I get to scan it.

The curve is pretty flat all the way across with max at 333RWTQ on our dyno or around 370RWTQ on a dynojet

...The car did really well on the dyno...I am very impressed how well this setup performs and drives...drives like stock until the turbos come on...and they do come on quick!....the sound with the open wastegates is phenomenal in boost and quiet through the 3in custom X-pipe implemented during normal driving...all I can say is WOW...this car feels like it should now!...more vids and pics on the way...stay tuned!...:driving:

Having owned a 300ZXTT with aftermarket turbos etc. 7.5 lbs seems low. The HP looks good. I'm assuming the 7.5 is for reliability with stock internals, correct?

Is there space for the Stillen Gen 3 intakes?

well the VQ breaths way better and has higher compression than the VG, having owned one you will know that you need about 20 psi for the same numbers we got with only 7.5 psi on the 370Z, this put the horsepower where we felt comfortable with on a stock block, it was almost doubled from stock.

don't want to find the limits on a customer's Z

no, there is so much piping that the G3's cannot be there and are not the right shape to get to the turbos if you want to use them as intakes

Any chance we could see the release of a kit which doesn't maintain stock drivability and the turbos don't come on quick?

I like that torque curve. Is this on 28's with .64 or .86? Looks like the cobb did an excellent job for a/f. I am assuming you installed a tuner kit since you went with cobb. What injectors are you running?
