Notchy, what track are you going to when the wheels and tires show up? I wanna see this bad boy in action?
Prob qualcomm or Barona raceway, Looking for some different rims as we speak. Found some nice Billet specifies but donno if I can swallow paying 500+ for a drag rim. But god they are sexy!

I would never run a 3.33 pulley on a stock engine without the wastegate, Even with the wastegate it windowed my engine. Broke the rod clean right below the piston. I Have a nice picture of it if you would like to see lol. I made more HP without the Torque booster on 10 lbs but the graph was just silly without it. No torque and the curve doesnt look anything like the CPR turbo. If I can find it ill post my 3.8 Pulley paxton Reving to the moon on E85 Vs my 10 psi CPR turbo graph also on E85, Same dyno same trans ext ext. True the paxton will get it done, Just dont take a ride in a turbo coyote lol it messes with you every time you WOT your car.

There was a car at addiction Motorsports a 10.1 with cams boss intake and paxton 2200 at 13 psi made 890 whp at 7800rpm....manual car I think beef build the car...so it can also be efficient just not as torqueeeee

Efficient is not just peak power. This cars heads and cams are untouched. If you want to see what the Paxton would look like at 890rwhp just move the end of the red line to the top right of the dyno graph. It will still be straight and lack power under the curve.

The best I've been able to do at Qualcomm is a 1.7 60'. Thats on full slicks at 12psi. It's still fun though, nobody else can hook either. Hope I can see the car run. You could always bring it up to Fontana for some 1/4 mile action

It's tough there. Half the time we're spinning when crossing the stripe. But it's a safe way to legally beat on your car and shake it down

What psi spring where you running in the wastegate when it windowed the block?

It was on the 11 lbs spring when it let go. Clean break on the rod, All other rods where straight and no signs of detonation or scarring on any of the pistons or rings. Let go 2 weeks after the wastegate install. Just to much power for the stock rods. Was running E85 also when it let go. Here is a pic of the block and of the piston.

Even in the upper rpm, peak to peak the turbo is ahead almost 100/100. The rpm drop on the shift puts the turbo almost 200ft/lbs ahead. Which is great and all. At 10psi the "old" drag radials don't even think about holding. We'll fix that here pretty soon

yeah im going for a t56 but im debating what ill do for gearing. currently 3.73 in the car and pretty much first could be entirely removed and second is still kinda useless at 8pounds of boost...
im thinking 3.55 should do good. with 28 inch tall tires id be at 165mph in 4th at 7000rpm sounds about right. ill prob need to test a few diff gearings
