11psi pulley on and running

Ibeyorsuperman · Apr 11, 2004

Well I got brave and uped it from my 9lb pulley to an 11. DAMN Kenne Bell, you are da man. For anyone who says you cant run 11psi on a stalk 2v they are wrong! As long as you have plenty of fuel, and enough octain, and no detonation...the car loves 11psi.

Infact it loves it so much, I ran dead even with an 03 Cobra with exhaust, 14psi pulley and a tune.

not to bad for a lil 2v.

Be careful. I would hate for it to go BOOM !!!!

Got any times with the blower? Pics?

Ibeyorsuperman · Apr 11, 2004

No times yet..next weekend. here is a pic tho.

You can see it on www.utahstangs.org as well

I run 11 psi, but at this altitude it is like running 8 psi at sea level and I run with a conservative tune. Good luck...

i would be careful running that kind of boost that you dont go boom, cause it sure does suck when you have to rebuild your engine.

WOW! 11 psi, isn't a bit much for a stock block? I was just thinking about upgrading to the 10 psi pulley, but was waiting for someone else to do do it first Are you running on 100 octane gas with that boost level? How easy is the pulley swap?

GinoGT · Apr 11, 2004

Just go easy on those crappy little rods and pistons.

DeadLurker · Apr 11, 2004

At what rpm do you see 11psi?

zgarske1038 · Apr 11, 2004

better watch your self .... you might be able to run that kind of psi but if you run it hard is where you will prob run into trouble

Ibeyorsuperman · Apr 11, 2004

Pulley swap was about 2 min. I see 11psi at about 2700 RPM and she just pulls all day long. I ran it hard for about 30 min, brought her home and checked the plugs. there perfect. no sign of detonation. Im running about 94 octane. Feels like a big block and I love it. Especially with my new upper and lower control arms, and the 315 BFG Drag Radials...really plants all that power.

From 2,700rpms...how long does it stay at 11psi? all the way to redline?

BlackBadGT · Apr 11, 2004

Dude, detonation isn't the only thing that will kill a bottom end... You're making WAAAAAAAY more horse power than those pistons/rods were ever meant to see. You'd be wise to put the 9PSI pulley back on until you can build up the bottom end.

Yes, it should. He might even see 12psi at higher rpm... Unlike the eaton roots, the KB boost keeps increasing with rpm That was confirmed on all KB tests in every magazine reviews!

Ibeyorsuperman · Apr 11, 2004

Well according to a couple mechanics at FORD they said as long as I dont detonate and have fuel it should handle 11psi no prob. They also said you would be suprised at how much power the stock block and internals could really handle.

So far so good

Horsepower doesn't kill motors.....detonation does. Period.

I've seen a stock DOHC (98 motor) with a T-trim....20 pounds of boost.....ran 9's. Made a crapload of runs safely while being shifted at 8200 rpm. Only reason the motor crapped was because they upped the shift points to 8700, the wrist pin snapped. The rest of the motor looked great.....even the pistons.

Good job with the 11psi. I'm insanely jealous.

Some people run lots of power on stock engines, others spin bearings on STOCK engines. Luck of the draw.

So true..

I would be afraid to put that pulley on mine without a built bottom end. But hey, if yours lasts good for you!
