Awesome Build!

[@powertechperformance8341]

Thanks, this was one of our favorite builds we’ve even done. Customers were great people to work for.

[@mustafajan5910]

Any overheating issues with AC on? And what temps do you get in stop and go traffic?

[@ThaProfeshional]

What rpm was the blower moving at? i see it had a 2.75 blower pulley, but no info on the crank size. Dyno graph looks like about 6700 rpm.
I just did a setup with a 454 lsx and a ysi. The car hasn't been on a dyno yet, but I'm spinning the ysi around 68,000 rpm

[@pauldenino3806]

Absolutely awesome build, pretty much my dream setup with the exceptipn of the RHS block.
Any issues with the msd airforce and boost also what compression ratio did this thing end up with?

[@powertechperformance8341]

The car ended up with right around 10.5-1 compression. The MSD Air Force intake has been a solid performer as far as holding boost. Much better than the FAST intake which always seems to balloon up under boost.

[@fb6_avery912]

What compression?

[@geradmg]

Any issues with the MSD under boost?

[@straight_intro]

Did you mix 93 octane with methanol or just straight pump gas 960 horsepower?

[@powertechperformance8341]

Era AG We used straight 93 octane then drained the tanks and filled it up with e85 right on the Dyno and continued on with the e85 map. Car had a lot more in it to give.

This is awesome... However don't LS9s have damn near bullet proof bottom ends? There are several ZR1s around my area (north Virginia) making 1000whp on stock bottom ends..

[@javilsx363]

What are the cam specs

[@3honkz716]

What size blower pulley?

[@powertechperformance8341]

I know this is a very late reply but we were running a 2.75” blower pulley.

[@casino8857]

What the rear tire setup he running???

[@powertechperformance8341]

CCW wheels with Mickey Thompson drag radials. With the car having a centrifugal blower it gives the car just enough time to start to hook up.

[@casino8857]

@@powertechperformance8341 cool man but I meant the actual size of the rear tires bro
