Why are my horsepower numbers so low?

[krummel45]

I do not know why my horsepower numbers are so low. You can check out the dyno run at www.dynosport.com(the name is brandon) My boost took for ever to spool and for the amount of pounds of boost I should be running near 380whp i would think. I was running 93 octane. Just to let you know the boost was creeping up to the 19psi. I called Force Performance and they told me that since I have the internal waste gate the boost will creep until 20 psi or so and than it could be controled. Also my torque is really low.

Do you guys have any ideas?

Thanks

Have you tested for boost leaks? I would start there.

Have you checked your compression recently?

You don't hit 20lbs till like 7500 rpms, definitly have a problem somewhere...

your main problem is that you start at 11psi and end up at 20. keep the boost at 20 psi across the rpm range and you'll make a ton more peak power. IMO internally gated turbos are hit or miss for creep.

I think you have the boost set to like 10 or 12 psi, and then you're just creeping from there. Set the boost high to start.

Can someone link me to the dyno chart?
