Def. A little bit of rasp ...

I'll get some video at some point.

Hey Chuck, what are there made of, ss?

Yea I believe so...

Dynoed and re tuned today... from when the car went in before the LTH until now , the car picked up 20 whp and 8tq...

thats with the LTH, Flywheel, and Polishing up the UpRev Tune...

That def makes me happy... I will post the graphs later tonight or tomorrow

nice gain! and you had TP's before, correct?

yea , but my car was running a bit rich before hand... the baseline dyno showed that i was very rich... not sure why...

also the tuner said my car wasnt taking as much timing as some other Zs he did... it would kick it back around 25 where other Zs take 28-29 degrees of advancement uptop..

also vvel adds 7 degrees of timing at idle for some reason.. another thing he said is unique to my car... I have no idea what to make of that though lol

But PPE headers seem to be worth something atleast

you seem to have the same problem Ive been dealing with since last November.
the ECU is pulling timing by 6800-6900 rpm down to 22-25

and during last summer I was getting the same 28-30 ign timing on top 7000+

I know the G37 had some noise problem coming from the VVEL actuator
I'm sure we are getting the same thing but Nissan hasn't seen the same problem on our 370z.

How did the g37 guys solve this. If at all ?

there is a TSB about this
apprently from what I have read about the subject , its mostly only a updated Ecu flash .
some reported that nothing changed though....:shakes head:


anyway I just placed my order with PPE for their headers
Stainless Steel 304 instead of the regular steel and Black ceramic coated 1600 F
plus an extra bung for my AFR snesor and a different extended size O2 tube

they are quite expensive !!
without coating they goes 1400 for the SS and only 750$ for the Steel one
I should have them in a month or less if im lucky !

nice nice... i should get some kickback for them because I have a feeling there will be more people considering them as well.. lol

I got them used for 550 ... SS dipped... mine were going for around 1200 when I got them,..

Yeah, I remember seeing those for sale and you definitely got a very good deal. I am still debating headers but the quality of these headers looks to be very good.

I have to admit I do like the way those headers look congrats on the numbers. I am in the market now for some I am trying to decide if I am going to go long tube or short.

Mr.Squeeze can you explain why you would choose one over the other? I am on the same boat but price makes me lean towards short. Thanks!

I already went with the short headers I just placed the order. The reason I did so was because I already have mortordyne ART pipes with a 02 bung in them for my wideband.

If had stock cats on I would have went with the long tube.

Im not him but I am in the same boat as you .

the reason why I placed an order with PPE for their headers is because Im looking for the most gain and staying NA

I already have the shorty header-HFC and/or Test pipe and Im positive that I will get more power with them instead of FI header

The test on the stock Nismo was +23whp +19ft which is alright for the first mod
Then chuckd05 got about +20whp but he also installed his flywheel at the same time ... let say he got half of it, only because of the PPE header.
He had test pipe +stillen catback
I havent seen much or any gain with the stillen headers if you already have HFC/TP and exhaust

also having a steped headers from what I have seen give more power than a conventional headers but at a higher price !

Thank you both for the response. :D
