looks like the headers also leveled out your A/F ratio some as well

 

I have yet to dyno my car....curious as to the results? I did notice a change in the butt dyno, however

 

Just got the TS headers installed. Butt dyno suggests an improvement but a real dyno this Sunday or Monday will tell what it really is.

 

I can't read the numbers on Daytona350z's dyno graph, can someone clue me in on what his gains were? Thanks in advance.

 

here is my old thread bout this.

daytona, how did the headers affect your exhuast sound? louder?

 

were these gains at the flytwheel or wheels?

 

Oh my, you ARE new. Dynos test wheel hp.

 

No, im not that new, i am getting confused though. what is the difference here....

wouldnt a butt dyno be rwhp?

 

oooHHH; sorry; "butt dyno" means what your butt feels when driving.

 

ahhhhhh, thank you. that clears that up nicely.

 

lil bit louder, but not noticeable to everyone.
only if you drive the car daily, you can notice the differnce. but i may add that you should get your headers coated before you install them. the underhood temps increased significantly.

 

cuz aftermarket headers don't have the heat shields the stocks do.

 

Enthusiast,

You may have seen this already but at least it was a good dyno of the TS headers. I also dynoed some plenum spacers I made too.

THANKS!

 

I'll need to see if I can find it when I get home... hopefully I still have it saved somewhere... Before the Vortech, I had a nice before and after dyno showing the Borla headers vs the Crawford headers.

The switch to Crawford showed a HUGE increase in low end torque and horsepower over the Borla. And since, the Borla vs stock was about equal, we could infer the same gain over stock. Peak power was slightly higher, but the big gains (and area under the curve gain) was on the bottom end.

 

Wow, i havent checked this thread in a while, seeing your sheet would help a lot man!!! Hope you find it man! the one thing I worry about with the crawfords is that I love in TX/OK and when I go to OK they salt the roads in the winter A LOT and I dont want to have bad rusting

 

Im looking for that area gain, as that will translate to the most overall gain in acceleration.

 

anyone tried the crawford headers yet

 

What your guys thoughts on DC's ceramic headers? They look like the cheapest out there. Does anyone have a dyno for those? Im really close to picking them up, I know every one says the crawfords are the best but by how much?
