ALOT OF HP AND TORQUE FOR A BASTID

WOW, 44 psi boost.

That really makes me want to do a little experimenting.

Maybe for the next motor.

Chris

hmm, twim 91mm turbos

NOTHING LIKE SITTING ON 2000+ HORSEPOWER  ;)

I have 1200 horsepower.... Maybe I just need to.

Take my Tahoe Horsepower + Nova Horsepower + Camry Horsepower + Pickup Horsepower = ok, maybe 1000 total    ;D

Can I add my model airplane and helicopter Horsepower to it also?

Chris

lol - don't forget your craftsman riding mower ;)

Oh yeah!  +22 HP

Chris

Chris, are you thinking about running a couple turbos on your next motor?

I have thought about it, still undecided. I just need to get my chassis dialed in with the current motor first, then make up my mind.

Chris

Hey I got I dea for you chris 1 motor to tuned your car chassis with and then another with turbos, another with alky injected blower and yet another as a nitrous monster Run all those and then keep the one you like best in the car and then used the others for display ;D

That's a great idea!  ;D

Chris

tell your wife i said your welcome and im trying to come up with yet another hobby for us to

CHRIS I KNOW THIS IS AN OLDS BUT HERE IS A SB TURBO BUILD THAT WOULD BE EASY TO REPLICATE WITH A SBC

That is awesome and a pretty simple setup.

Thanks!!

Chris

I think I will try to find the formula for choosing turbo size based on boost and cubic inches.


Chris

YOU FIND THAT FORMULA YET?

No luck at all. I am still looking though.
