the head has fire rings and valve springs with haisleys retainers/ keepers but no port work at all. it is an area where I could prolly pick up more horsepower from.

the charger is from Brian Block (kta cummins) it runs about 50 spi boost

egts are toasty under wot but normal driving 600-800 driving down the road. it will get 1500+* but your at 120+mph by then so its time to let out any way I noticed the temps seem to really climb fast as the governer starts to pull fuel out and thesmoke starts to clean up

 

That is interesting, I figured you had a ported and polished head, but you do have a different cam correct? Who's is it and what kind of RPM's does it support, does it help the spoolup?

 

yes I have a cam and it is also from Brian Block (kta) its one of his profiles. i didn't notice a change in spoolup because the cam and charger went in at the same time.

it makes peak power at 3000 and the truck is still over 500hp at 3800 where it hits the governer.

 

Does KTA have a shop somewheres?

 

yeah, the back of john deere in shelbyville ky.
he does most of his work there but he has machine tools at his shop at his house he uses for turbocharger work, pump work, ect..

 

Nice sounds like the dude knows his stuff tho!
