Will anyone who has done a dyno after adding a set of headers to their car please post their sheets or #'s. Im trying to decide what brand to buy and need some help finding the best HP and torque gains. Crawford, Nismo, Stillen, etc. would be appreciated. thanks!

Anyone out there who can offer suggestions or post info?

 

I'm in the same boat, but i'm pretty sure there are very few dyno charts that are showing just header results. From what i've read in posts, it seems crawford and nismo are the best with hp and torque through the range. It is an awful lot of money though. I was recommended a couple time to just use the money towards the Vortech kit i plan to get instead, lol. I'm not sure at all what i'm going to do

 

I actually have a dyno sheet for the headers I have installed in my car....no other mods - so its definitely pretty good for you guys since that's what you are looking for!!! The headers are the Alphawerks Racing Development headers that just recently came out and let me tell you...they are awesome!! Now I have to go to my shop to pick it up, so I'll swing by to get that hopefully sometime tomorrow to get that up for you guys.... but it added an extra +21 bhp/ +15 tq

Whew oddly low baseline...

Actually looks like numbers our Zs make when they have been driven around conservatively and then put on the rollers.

Question... why 16 runs for a baseline?

 

Dont listen to this guy he is affiliated with Alpha Works....that dyno graph and the gains claimed are the exact same ones in the Alpha Works ad found in recent Modified Mags-Im looking at the advertisement. He is prolly the same guy that came on here before talking up these headers then he dissapeared. All those runs-you took the lowest baseline and the highest with the headers. You can go away now, and let me say you have been OWNED!!! If you wanna advertise your product pay your vendor fee like every other reputable shop on here

To ZLUVER-if I was going to stay n/a and get headers Crawford would be it if I had no price limit. For a lower budget the Topspeed headers have done well.

 

If your going to go for supercharger its ok to get headers but if you ever think you may go with a turbo its a waste.

As for the alphawerks guy, I thought the rep said they don't even have any more in the states till next month. Also no use to argue over if this guy is bs or not we should know alot more about these headers soon enough.

 

It is B.S> same exact graph. And he is long gone already what a loser.

Anyway I am still waiting to see dyno numbers on those Topseed headers...anyone?

 

i know you saw zachrosen's topspeed header dyno.

 

I know but hes auto + all of his mods have been very dissapointing.

 

i'll be having mine installed and dyno'd mid-Jan or sooner. i'll certainly post results. its hard to believe that out of all, like 40 people who bot those headers, only one dyno'd them.

 

had to resize

 

Hey daytona350z, what kinda headers you are using?
