RAIN H8R

I had a tuning session at King Motorsports yesterday. Only modification change was the J's header. I went from 364 up to 379, with a gain of apprx 15whp, and from 224 to 231, which is approx 7 torque. I'd say they gains are worth the cost of the header. Next is Sideways's cam timing keys, hopefully Ill have those installed within the month.

Sweet results! Now you have to try the Hytech header! hahaha!

No, I am running a JUNK2 70mm Test Pipe, and a J's 70RS Ti Single

RAIN H8R

Ill leave the Hytech stuff for you. Ill just keep running crummy J's parts

Shabadedoo

sick.. i'm wondering if the berk header is similar in design to the j's

RAIN H8R

I dont think it is, the J's is pretty much the only mass produced header that is proven to gain power when tuned properly.

i got a 1220 n its pretty nice to see the gains in the smallest pulley applied. you never thought about upgrading the blower to the 1200?

I have thought of it, alot. Problem is the cost. 400 for the upgrade, new pulley and belt will be 110-120, plus tuning 300ish. I am kind of waiting or 928 to figure things out with their impeller upgrade before I jump the gun on the 1200 impeller.
