dual 3" or single 4" Pitt... hands down...

 

I didnt even know pasesetter made 1-5/8 headers?? maybe thay do iv just never seen them before, but yeah i shur hope its not 2" couse stock is 2.5", but i would say atleast 1-3/4 headers, duel 3" y pipe, and a 3.5" there back. but anyways my 5.3 always ran a tenth better with the cutout open, i think it pulled better in the mid range.

 

Well I am done now. Something up with the motor...down around 25/25

My mph drop wasn't the weather. I was down 7 mph last Sunday. On the dyno, I am flat lining rwhp at 4900 rpm across the entire band and torque drops off drastically at 5000 straight down hill ??? Guess I will run a compression test Sunday to see if it is rings. Really weird as I am not blowing smoke or using excessive oil. Also it was pulling timing from 26 - 22 once in a while with no knock ? Nothing consistant except loss of power at 4900 rpm. I am really stumped. Damn the bad luck !

 

sucks to hear that.. let us know how the compression test goes.

 

man pit that really blows man, sorry to hear about the issues just hope its nothing to damn serious.

 

damn pit hope it is not nothing big,some easy fix would be nice right.haha hope your luck is better than mine.

 

Thx guys. Gonna pull the intake and clean out all the oil, chg plugs and do a compression check and look for air leaks. Gonna start simple because it still runs as smooth as ever and isn't missing or smoking. Almost like a breathing problem though. Maybe I sucked in a seagull at the track last week...lol

 

i wonder why it would be pulling so much timing without knock? those are really strange symptoms out of nowhere.

 

Yeah, and it didn't pull timing on every run. Weird **** going on. I think I'm gonna run it anyway !

 

so were the temps ok? about the time it pulled timing?
