Im thinkin about gettin a 2# upper to go with my 4# lower i know my truck is running pig rich right now cause i havent gotten it tuned yet with te predator. DO u guys think it would be a bad idea to run a 2# upper??

 

Most guys here will tell you that you don't run any faster with 6# Rob02 even said he run better with the 4# 6 is just too much the Eaton makes too much heat to gain much at that level of boost.You gain some bottom end but the heat will hurt up top.I;m just staying with my 3# and the Preditor.

Here's you:



...and you know what they say about playing with fire?








get a Dyno tune!

 

I have a 2.8 comming. I might put it on the L but i will porbley put it on my cobra to replace the 2.93 thats on there

 

I have a 4#lower and 2.80upper. My track times do seem to be in the same range as L's without a 2.80 upper. My boost levels are
in the 13-15 range depending on weather which is where the 4# only guys are.

I dynoed at 377\466 with chip\and 2.80 upper\k&n drop in and holes in the stock box. The chip gave me a solid 24rwhp and about 38rwtq. Take away the chip and the difference to me is minimal if any.

 

i dynoed 355/471 the other day and it was pig pig rich.. Im going to get it tuned but i think im also going to have the eaton apton ported then throw the 2.8 on it. And also going to get a heat exchanger for sure..Then we will see how long the engine last lol. IF it blows up that gives me a reason to build a built bottom end so i dont have to worry about anything.The only thing is i need money lol hahah
