Loss of power

[anders]

Hi!
Today i had the TTA on dyno and it dont like to make any moore power even with extra boost, same hp from 21 to 26 psi.
Se the attached file.
I dont like this camshaft 224/224 i am current running, my old 212/212 was more fun at lower rpms, i am going to swap in a 212/218 soon and hope that helps me to run stronger at low rpm.
Coult it be the downpipe 3" that restrict the power(dont use any exhaust just a short outlet at the passenger door.
Or springfloat ?
My goal are atleast another 100rwhp.
Heoe you can se my mods at the sig.

Any suggestions ?
Thanks

Sounds like you have to tune it better. A 3” downpipe is good for 6-700rwhp prob even more . Are your springs setup for the cam u are running ? What are your pressures open? Closed ? Are u getting any detonation?

That's a pretty stout build. I would think you should make more hp. You may want to contact Bison for advice on what valve train set up to run with the 218/218 cam you plan on running. He might have other suggestions for your engine too.
