The 305 baseline was with Gen3, test pipes, invidia gemini and John's tune.

Current setup:
Stillen Gen 3 intakes
Momentum VQ35DE Headers
Test pipes
Straight exhaust with glass pack mufflers

Tuned by John @ Z1, played with the VVEL tuning too.

Wad??!!!!!!!!! Does the headers help alot?

Nice #s

yes, the headers help a ton. Z1 shop car has them also and they also so close to a 30hp gain.

Pretty impressive! :tup:

Dang, are they the same as the stillen headers?

Major gains! Nice.

no, they are for a 350z, and Momentum is now out of business. They just require 350z test pipes to fit the 370.

Nice! :tup:

is this real? lol that is a lot for just headers.

Is our headers that inefficient? How does the car feel now?

Edit: I also wonder how this would do with a BP or STS turbo kit.

??? so you used 350z headers? and wouldnt the stillen ones provide the same gain, from what i read they dont

Its real, I'm the second car with this setup with similar results. Mine are a little higher due to the rest of my exhaust though.

The car isn't registered for the street, but I snuck it out for a quick run from 1st through 4th gears and it definitely feels much more powerful. Find out for sure when I go back to the track next month.

I was planning to used some tomei 350z headers with z1 pipes but they r too much work n cost forninstallation. =[

I bet that made a ton of difference up top -- at least 10-15 whp any details on what he changed? More lift? Changes in overlap?

When will these maps be open to tuners??? :excited:

I don't know the particulars. I know I was around 330 before tuning. I don't think he used a canned map though.

Well, then -- my guess was probably correct :)

You picked up 10-15 whp from a tune that also made use of VVEL adjustments.

Please see if you can get any more info :tiphat:

those number in STD look good !
I ended at 330 last year and im pretty sure with some VVEL tuning it would be pretty the same as you !

they said the only thing left I can do for more is exhaust cams. maybe in a few months :)

Jordo, just PM John@Z1 for info. He is the tuner.

Nice numbers got me beat... For now

That's awesome! :tup:

:tup:

I also lost 40 pounds by getting rid of AC, swapping radiator, headers and transmission mount.

I can't believe I lost 16 pounds on the headers alone!

Lol thanks for the shopping list!!! I don't want to ditch the ac bc I still need to drive to the track :(

u ditch the radiator and ac at the same time I'm guess?

what radiator are you running now?:driving:

Any 1:1 or 5th gear pull?

Great numbers....the beast keeps getting leaner and meaner :tup:

wow... very impressive

Headers 16
Csf radiator, ac condenser removed 4
Ac 18
Trams mount 1
Z1 silicone hoses .5

I don't know what gear they dyno in, but hitting redline in 1-3 and then going into 4th on the street was probably a little more than I was comfy with as it was without registration or insurance

Makes me want to get headers now! Impressive dyno. Z1 should copy the design for a direct fit for 370z.

Nice Mike. :tup: I'm now wondering about this with FI LTH's.

Mike, any chance you can get the drf's? If so, would you mind emailing them to me for my database at jlitman@mail.usf.edu ?

I would say ask John. It's fine with me if he givesz then to tiy

Congrats Mike! Damn fine results sir!

This header set up shows more gains than fi Long tube headers?

Mike why did you decide to go with those headers

Impressive gains especially considering that the entire power band got shifted vertical.

because Z1 had already shown similar gains on their own car. More gains than some long tube prototypes that they had developed, and they wanted to verify the gains with my car.

btw, Momentum is no longer in business, but Z1 is developing their own version of this header, specifically for the 370. They should have a package available soon.

apparently he knows something we dont!

so if i am already dyno tuned could i expect another 10-15whp gain? if so i will be around 340whp as well :stirthepot:

im liking the numbers that are starting to come outta these motors lately

Thanks for giving us the opportunity to work on this beast Mike!

Here is your before/after graph.
