TSM makes 357RWHP NA on a Stock Longblock VQ37
 

For those of you that may not know me, or TopSpeed Motorsports. I encourage you to check this our as well. http://www.the370z.com/introduction/71910-topspeed-motorsports-introduction.html

We recently had the opportunity to complete a very interesting Naturally Aspirated project on a customer's 2012 Nismo 370Z. Allison (allystephy on here) pretty much gave me free reign on the project, her only request being that I make more Naturally Aspirated power than I previously had while working at Z1. My previous best was low-mid 340's on pump gas, and high 340's on E85, needless to say, after a little more R&D on the VQ37 we made it happen.


I believe this to be the highest HP ever recorded by a Stock Longblock Naturally Aspirated 370Z/G37 on a Dynojet.

Great job Rob!

What were the run conditions and the actual correction factor value(s) for those runs?

On that note, what are the values for SAE?

Baseline 272
tuned 340 (93octane)
only a gain of 68whp with tuned VVEL and a secret mod ?
hehe :tup:

I had he same result of 68whp without a truly tuned exhaust and VVEL on 91octane 2 year ago before I blew the engine.

I'm not bashing you guys but this show my point right there...

There is quite more still to be gained in N/A form with the stock VVEL engine.

Anyone can make a baseline number low, the baseline number I posted is a representation of a legitimate test of power of a stock car, and actually under better conditions that the modified runs. People seem to have a much harder time making legitimate power on modified 370Zs.

I didn't argue with you btw. and 272 is about what Ive seem a Nismo run on a dynojet (a bit low but close). so yeah I do believe the end result without a doubt.
The major point I was bringing was there is still more to be gained.

Of course, there always is. I have no doubt this same car will make 360+ under better conditions and a little more tuning, which will happen in the very near future.

The CF values are a tad on the high side (STD must have been 1.05 - 1.07), but those are still very impressive gains.

Hmm. I'm thinking some serious massaging of the TB's and intake porting must have been involved... with larger diameters and pnp I bet there's plenty to be milked with VVEL tuning.

Proper VVEL Tuning resulted in a large gain, STD was 1.05. Uncorrected was 340, but conditions on the dyno were horrible that day.

Those are good numbers!!....it would be nice if you guys make some headers that can bolt up to other non z1 pipes and exhaust

Again, very impressive. A cold day and you guys will definitely see over 360.

Was the VVEL tuning with uprev or ECUtek?

EDIT: Sorry, you answered this in the other thread -- uprev.

Well, my hats off you -- looking forward to more results :tiphat:

Impressive, Rob!

Is that a 350Z exhaust?

Specifically, EXPREME?

Will you not give deets on the mods? Kinda vague if someone wants to duplicate.

From what I see its a intake (modded:confused: ?), fuel system (255 and injectors? but shouldn't have an effect on the 93 gas run), possibly ported everything? , header, TP, and CBE, yet like 20-30 more than anyone else on average (talking about the 93 SAE run). Either you tune what others can't or if you did port, it opened up a world of extra power. Or possibly both. What am I missing?

PS I can't find a flaw like from most tuners/manufactures so hats off to you.

Anyone else agree that 7900 rpm is to high specially since it bounced off the rev limiter and lost power after 7500? Seems scary knowing some have blown up there. Megan what was your rpm at?

I was just unlucky and getting oil starvation which isn't the same.
I wouldn't be afraid to rev again to 7900 if I had the VVEL engine back in. (rev limit was 8050 and used only when needed.) ;)

damn i want my car with that powaaaaa :tup:

Nice... TSM is my fav shop. They do good work on GT-R's wanna see a 370z with swap 350z heads and cams

Nice! will you be making proprietary components/mods of this kit available to the public?

I think what most important here (after highest NA HP) is the fact that you can bolt on to your own exhaust and pipes...this will create a bigger client base since ppl won't have to go change their setup ...it might have some small variations in output but I'm sure a lot will appreciate the fact that they can keep their exhaust that they payed a lot of $$$ for.

Sick car and awesome gains. Love seeing this kind of stuff coming out of the Atlanta area.

I am curious as to what was modified on the intakes. Did you just enlarge the opening where the tubes go through to the front bumper so it is unobstructed airflow similar to the Stillen G3?

That Tomei :yum:

video for the tomei
youtube ZAtlanta exhaust competition she is at 4mins

O gotcha.

There's nothing mentioned about an intake manifold. I'd be interested in a TSM intake manifold if it puts down more power than the z1 and m370 manifolds.

It's likely covered under the TSM Proprietary Mods as he was the one behind the Z1 manifold mod.

Did you use stock cams?

Come on TSM, show us that Stillen S/C haha

sooo my main question. are we gonna get access to any of the stuff that made these numbers possible? or is this something just to get TSM's name out and about for now?

edub i got you.

is the girl who owns this Z good looking? if so i'll get the info out of her :yum:

:tiphat:

I believe he mentioned in another thread he would be willing to sell any part of the package to interested parties, but won't release specific details for the competition to replicate

See, that's the catch. I'm interested and curious about how it would work on a boosted application, but I'm not going to put something on my car if I don't know what's been done to it or why.

Seems fishy to me.

What parts are for sale, how much, what kind of gains can be expected? Without this info this reads as, at best, a bragging thread for a one-off lucky build. At worst, dyno manipulation for big numbers.

You will never get the info out of me :yum:

is that a challenege? :yum:

i'm sure i could pump you for some information :tiphat:

glad soemone got it lol

I see porting being done. Not rocket science to me, only one way to skin a cat. Not sure why he mentions Z1 not being able to do as good of a job as him and making less power but my porter will take as little or as much as I say. Maybe I'm missing something but soon IPS and I will have the whole system ported out with tuning. I'm at 295hp with similar mods on a dynojet with SAE correction. Since he posted 340hp SAE it looks like we have 45hp to make up with a tune and ported intake system. If we don't make it there could be differences within the tune. I say anything within 10hp would be a fair equivalent.

I think you missed the part where he said he learned some new tricks working with the new company. Sounds to me like he improved on the process from Z1, which makes sense! There's gotta be more potential HP out of these motors NA'd!!
