Has anyone kept their dyno#'s for a long time? I would like to see how much you gained from a #4 to a #6 and then added a port on the eaton with final numbers.I would like to see on the same truck.If you didn't gain much from 4-6#,did you see any gain at the track? ect.Oh and at what point does your fuel system need upgraded? If I go with a port and a #6 should I up grade the injectors or pumps or both? My truck is going in for Manley rods and pistons this month and I will not have the money for a new blower this year,but I can swing a port,#6 and a tune. Thanx

 

I would consider the fuel upgrade, I'm running a 6 lb pully with a magnum powers on a built block. I have 60 lb seimens deka injectors and stock fuel pumps. combo works good.

 

Thanx silver

 

I had a 4lb lower with a stock eaton and pushed 389/476. with the ported eaton it picked up to 417/488. The gains were almost across the board and not peaky at all. After going with a built block with stage 2 cams and stage 3 heads the power jumped to 470/534 with no pulley change and an a/f of 11:1 on the ported eaton. That was at 11.7 lbs of boost. Theres nothing wrong with a ported eaton. Im hoping to be close to 500\600 with an 8 lb lower after the break in tune.

 

Thats the info Ive been looking for,thanks.Any track times yet? and what port?

 

sorry, no tracks times. Its a stage 4 stieg port. I was very happy with the gains from the port though. I like to do a couple things at a time. If everything was done to it what would I have to look forward too? that's why I don't mind spending a few hundred bucks on a ported supercharger and getting a whipple or kenne bell a couple years down the road. It keeps things interesting. :-)
