" I wish i could help but i am waiting on a group buy or some vendor who is willing to offer me a good deal on MAGNUM POWERS thanks

 

You might get one additional pound of boost!!!

 

honestly, I haven't heard anything bad from those who went to reputable porters. (APTEN AND THE OTHER BIG ONES)

Doh I wish I knew the exact numbers but basically, when I was being tuned with my current mods (6# JLP lower, ported eaton, JLP Ram air, 90mm maf, phenolic spacer (that's about it for intake mods)) I learned some interesting info.

My air Temperature was a little lower to the same, as a stock engine at the sensor. So anyone who says a 6# creates too much heat to be effective, needs to have their eaton ported so that more of the intercooler is utilized.

Did I gain power, YES, going from a 3# to a 6# and eaton porting I gained over 38rwhp and over 23rwtrq.
(and I only have a conservative STREET program)
Had I opted for a more aggressive street or race program I would have gained more.

 

don't have #s but mine ran very consistant, used to loose a almost a tenth each run, after port stayed witin a tenth all night. and blowercase was much cooler, used to burn hand on case,after each run, now it just feels warm after back to back runs.

 

I good friend gained 21 horse on the same tune.
