no that will be tomorrow at RT. The runs tomorrow will be compared to run 25 which was right after the headers were installed.

Here is my same day dyno of the headers.

 

^^ R/T Results ???

 

Dip is still there, but not as drastic. I plan on going to the track soon and see if my 60ft change back to normal.

I have the topend just my launches are slower now because of the drop.

Before the headers I would run 13.8@101 with a 1.9-2.0 60ft with headers 13.8@104 with a 2.2-2.3 60ft.

PPE is looking into my issue.

Did you ever get any answers and is PPE doing a redesign?

 

I should be installing my PPE headers by the end of this month or 1st week april if my cams come in. Will be good to have 2 different results to compare with.

Maybe I have one last thing to try out which I was going to do anyway. Change my exhaust. I'm doing that next week.

A HR 350z just had these installed and he as a lowend drop also, but his is not as bad as mine.

He is also using the stock HR exhaust only mods are the headers and intakes. He put down over 300hp@ uprev.

Skidz what cams are you going with?

 

agreed! i got my tdx2 on this weekend and cant wait to add these headers. im trying to hold off and wait on the "final revision" if there is one. based on what ive seen with a lot of the domestic cars im used to modding, its not that unusual to have a power dip down low where the curve was shifted up. these headers picked up a lot after the dip over the best possible shorty/tp combination. with cams and a cosworth i think they have their place.

 

you guys should be good since you are 6mt you can rev past the dip.

Here is why I'm going to try a different exhaust. Go to page 5 and read their exhaust tests.

My dyno looks like the one with the crappy custom exhaust.

Granted this is with SG headers, but it may apply to me since my exhaust is smaller than 2.5. My exhaust is 60mm (2.36in) the guy with the HR is using a stock HR exhaust.

His exhaust is 2.5, but restrictive. I was told by the shop making my exhaust that since I'm now pushing out more air due to cams and LT's I need a free flowing exhaust to support my new mods.

I'm going 2.5 dual with custom x-pipe. If I get the majority of my low end back to where it was I will be happy I love the midrange and topend.

After 4k it hauls.

 

Have you used your nano kit yet?

here is what the 350zHR put down.

Mods intakes and longtubes only

He was not tuned when he pulled 275 he only had intakes. The 301 run is after the LTHs and a tune@uprev.




The HR headers are identical to mine. I'll take that little loss down low my losses in that range are 214tq (b4) -194tq, 157hp (b4) - 142hp = - 20TQ/-15HP between 3200 and 4200.

 

no not yet. i need a few more parts (odd fittings and hoses) to mount everything under the wiper cowl and have the lines exit like i want to. then ive gotta pull the plenum to drill the holes for the bulkhead fittings. i havent been able to afford any downtime this semester. im always on the go. i am gonna get it finished up pretty soon and then get the fuel as close as i can myself with uprev tuner and test it out on 75hp before going to uprev and having them tune it at 125hp. i need to find someone GOOD to do the cams/longtubes/cosworth install in the austin area when i finally do head down there in may. ill let u know how it runs on the 75 shot+nano before then though!

good lookin 1/4 runs BTW!

 

Ended up with Tomei since my trusted local parts guy got me a good deal. I got the 272 in/ex.

 

Tomei cams and headers? or just Tomei cams? Are they installed? Do you have your numbers?

 

He has Tomei cams and PPE LT headers. Not installed yet.

 

Has anyone tried or planning to try these on a DE WITHOUT cams? It seems like that would be a much bigger market for them than cammed cars.
