Guessing HP

zae757 · 07-30-2014, 08:09 PM

I currently have a base 370z 2010. I've added several aftermarket parts for performance and haven't been able to find a shop to tune it in my area (that and my job keeps me too busy to do so). I was wondering if anyone could guesstimate the horsepower just by the parts (and if anyone has the exact match with tune, it'll be great)...

1. Stillen Gen 3 intake

2. Injen CBE

3. Berk HFC

And soon to be Stillen headers. I only want to do all motor. FI sounds nice and the numbers are great but I just don't want that headache if not put on properly. Any assistance with this would be great...

302 my guess.

295

Less than what Nissan advertises the horsepower to be on the 370Z

disclaimer: Nissan advertises crank hp. **** waving with the FRS crowd adds 10 more hp to the crank ~ 2 hp to the wheels

Question is, are there people out there that are willing to post there all motor dyno sheets? I'd love to compare and contrast until I'm able to hit a tuner shop

Tuning - Nissan 370Z Forum
Start looking around in that sub. there are lots of dyno charts available that show base line HP with mods before tuning.

I'm driving up to Z1 on Friday. I'll post up the results when I get back.

Intake, Bored Throttle bodies, Z1 Upper Manifold, LT Headers, CBE, Pulley, Flywheel.

200 < hp < OO

313

308 whp. Btw, Stillen headers are not worth the trouble. The gain from the header is very poor. The stock headers are well made; it even has heat shield.

and way less than what the makers of those add ons claim the HP increase is as well. only true way to tell is to do a before and after dyno with a tune. yeah i know there have been proven increases with some mods (like the FI exhaust and the stillen G3) and those are the exception.

yeah, never understood why to take off perfectly good factory headers to add headers

i can see it on the older 350z that had the cast ones vs true headers that was a increase when you added them. cost vs gain with the 370z is not worth it IMO

Make sure they use SAE!

Completely stock 370s put down about 280 whp. Mine was 297 whp with a Stillen G3 intake, Berk HFC & Berk CBE on a Dynojet. After Uprev and custom tune I was 324 whp on the same Dynojet. My numbers are very typical with those mods and a tune. The tune made by far the biggest improvement in performance. The exhaust made the car sound great, but the tune improved drivability, throttle response, and performance.

Dynojet is too optimistic. I used Mustang Dyno and I got 261 whp for the stock Z.
