Impressive, I can't wait to be up in the same area boost wise. Any reason you didn't go with straight water?

Impressive results.

Do you have a log / dyno sheet showing the boost curve.

I didnt have the dyno connected to boost but it comes onto 30psi by 4400 rpms. here's a pic of the 6766 someone took of my engine bay down at rotorfest.

30 psi @ 4400rpm

No wonder it has such a fat power curve

You taking it back to the strip to see what it will run now?

Sorry meant to say 20 psi by 4400 rpms. 30 is shortly after at 4700. I won't be able to make it up this year but should do 145-147 mph trap going by the vbox times .

Not bad at all, on a short runner manifold as well. There is more left in that turbo 67/66 1.15 A/r H-cover still we've ran them well over 40psi on the dyno here and have still seen gains. I see no reason you wont get over 700whp.

Nice work!
Be careful driving it on the streets! At that power level, things can get squirley!

yea she's a handful to drive for sure. i only run on drag radials or r888 and only just have traction for 3rd gear up. 1st and 2nd have nothing even on pump gas at 575whp its very hard to hook. blast to drive though turbo hits hard.

stock tranny number 5 and t2 diff. clutch is an act 6 puck right now but its not happy in the 600 hp level you can smell a bit of clutch after a pull on the race gas. looking into changing the disc and it should hold ok after that.

I just about wrecked my car yesterday. It was cold and my tires were just my street tires. Hit 2nd gear and it immediately started sliding sideways.
I have a problem getting traction in 3rd gear too.
