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.
