Posted this in the External section but thought you guys might be interested too.
Well i threw the headers on today. dynoed it a couple times, swapped out and dynoed a couple more times. The results were pretty much the same. printed it in MPH instead of rpm cause it looks more like a normal graph.
It sounds a hair quieter at idle and a hair louder while driving, but it also sopunds a little deeper. I'm happy. Next up is to throw the dinosaur in it.

 

Interesting. At least you have stainless and room to GROW.

 

You trap 121MPH with 335rwhp? Is your car cut in half with a midget behind the wheel?

 

throw that dinosuar in it so when u drive by my work i can wake up in the morning and hit me up with a pm juan

 

Almost and no i'm 5'10" and weigh 190.

 

goes to show hp isnt everything.

 

But weight is. I'm damn near religious with my weight reduction. and still have ALOT more i can swap out and take out.

 

did you retune for the changes in parts?

 

Are you serious? its just a header swap with the only difference being 1/8" in the primaries diamater.

 

man i bet you cant wait to het the dinosaur in....its gonna be bad ***

 

Yup, got all the parts, just don't have the time.
Customer cars come first.

 

quite interesting. I would have bet the 1 7/8 would have some significant losses.

 

Hit the track & keep us updated buddy

peace

 

What does "SI" mean?

 

Stock Internals I believe

 

yes it does .

peace

 

very nice Juan! I can't wait to see what that swiss cheesed SS does with that dinosaur cam!

 

Actually, a retune would show the difference in the header designs. Even different 1-3/4" headers of different length/diameter primaries/collector design can show 10-15rwhp differences at different RPMs when optimally tuned.

Because the graphs look identical means the tune is the restriction.

 

Juan have you even retuned it for the 90/90 yet? I would say that with the 90/90 and the 1 7/8" headers that it needs to be retuned.

 

Yeah it was tuned for the 90/90. It was a little on the rich side though. But i haven't had any $$$ for a retune. and when i throw the Dinosaur in i'm going SD.
