the y7 uses different pistons, and the stock y8 compression ratio is higher as well. so
that means the y8 will always make more power than a stock y7/y8 mini.

Whatever the case, you're going to lose power from that absurdly large throttle body....

Take the money you are gonna spend on that skunk2 unit and put it into a stage 2 bisi cam and valvetrain, with those p29's it will be very very nice.

Build it, dyno it, and then tell us. Every engine is different and is going to respond differently to the same mods. I've seen guys hit 97whp w/ that set-up and then there have been guys who make 125-130ish.

127 to the crank not the wheels.

Your TB is way to big, and will probay make you loose hp.
Your MSD setup will give you 0hp just so you know.
I'm guessing 109 whp with that set-up.

I guesstimate a D15B7 with IHE, Z6 intake and TB, A6 cam and Y7/8 cam gear will kick your high dollar parts.

y7/y8 compression is 9.9:1, .3 over a stock y8.

i know first hand

I guesstimate 110whp. I agree with the others on the TB. Compression will be high as hell since the y8 head has a smaller combustion chamber than the y7 in combination with the p29s?

I'd hope you'd also invest in a cam and some sort of engine management.

If you make it to a dyno I'd like to see the numbers of this setup
