GT Motorsports Dyno the First 370Z in the US: 290 RWHP!!! (Approx.)

Good job guys!

Quote:

Well our 370Z test car finally arrived, it is not easy getting one
of these right now since they are still so fresh. We are currently testing the stock engine with our GTM VHR Test pipes, and are also developing a 370Z Catback exhaust system. Dyno results will be posted for both once testing is completed.

Looks like we are going to build the first twin turbo 370Z, which should be completed within the next 30 days. At which point we will be taking orders for our GTM 370Z Twin Turbo system.

We are very impressed with the power this car puts out in N/A form, nearly 290rwhp! With test pipes and exhaust we should be over 300rwhp. This model Z is lighter and feels much tighter than the 350Z. This platform is going to be the ticket for road racers, especially with the available Syncro Rev-match on the sport models!

Enjoy the pics and graph, more updates of the progress to follow.

BTW, did you guys take a video? I wouldn't mind watching that video

Sweet!

WShade · 01-14-2009, 10:37 PM

Great info thanks.

Would have loved to see a HRZ and 370z, both bonestock, back to back dynoed on that same dyno, same day etc just to put things into perspective.

There are various flavors such as Dynojet, Mustang, Dyno Dynamics, and Dynapack. Some models, like Dyno Dynamics, have load barring so it reads lower. My friend's shop has a Dyno Dynamics and is known as the 'heart breaker' dyno because you'll see quite less HP than you would say, on a Dynojet.

People don't like Dynapack because the number reads quite high, not to mention that it's a pain to do. You gotta take off the wheels and if you have an AWD car, you gotta do all 4 of them.

I don't think any particular dyno is better than the other, as long as it's SAE corrected so you have a realistic reading. Dyno just gives you the stats for your car, pretty popular for hobbyists as they like to know what this part and that part add in term of power.

But if you want to do dyno tuning, I'd go with a load barring dyno to simulate the conditions of the roads.

290 RWHP is quite impressive, especially in this strange heat wave we've been having in SoCal the past week.

What are the costs to get your ride dynoed?

Depends on your car and shop you go to.
I know the shop near my father's shop does it for 500 but he hooked me up when I took my dad's car for 350. It ranges from like 350-600 I believe, I can be wrong.

It depends on your car, the shop, and if you're going by yourself or is setting up a dyno day event...2wd is a lot less than AWD. At some shops it costs a bit more to get the A/F reading as well.

Typically for a 2wd car with 3 runs and A/F reading, it's usually about ~$100 and ~$200 for AWD car. This is from my observations of the shops I've seen in my years on the different car forums out there and the shops I've visited/hang out at in real life.
