I'll post dyno specs and info in the morning, currently at my work in my desk.

 

I'll be waiting......
Patiently..

 

Sounds like someone found a generous dyno out there.

Seriously though, I'd believe it if that was the readout from the crank. Bone stock, a G37 puts out around 270 whp. No offense but I don't think your mods with a tune warrant an 80hp increase. It just doesn't seem realistic.

 

Sounds like a poorly setup or calibrated dyno to me.

 

Here are the dyno sheets

 

So now we don't even take dyno numbers as proof? What does a guy have to do to know what his car is worth?


Do you have a 1/4 mile track around?

 

I don't think anyone has gotten anywhere near those numbers and he only has exhaust/intake done. Drag strip is the best place to show gains. When I had my supercharger done, two different local Mustang dynos were giving me numbers 30awhp in difference. Either one of them didn't strap it down correctly or their dyno was not calibrated.

 

I'm Just trying to share my dyno experiences and what I have done to my car. Yes I live about 35min from Sonoma Raceway aka Infineon Raceway aka Sears Point Raceway. No I have not ran it at the track. I agree with multiple responses that the dyno could be un calibrated or could have read wrong. The only other mod is a stillen lightweight pulley and that day I believe was colder then normal. For the individual trying to call me out and my credibility, call the performance shop and see if they can do anything for you.

 

Well I'll say congrats if they are real, I'm super jealous. A few guys are just weary since most with those same mods and even more don't ever reach those numbers. Your tuner is a God!


If you're super concerned, just ask the tuner the last time they had the dyno calibrated, that'll alleviate a lot of questions.

 

Next time I'm there I'll ask and see what's up. We're going to probably do a stillen supercharger. They have done a g35 auto and a g37 auto that made nice numbers. They are more known for turning Subaru's. They also help out a few of the local drift teams out hear in NorCal. As the build progress I'll continue to post. I still need to lower and put wheels on so of course I don't plan on much more power mods until I get that done.

 

Any reason why you don't want to go with a turbo setup like BP? I honestly don't feel the Stillen kit as it stands is worth it (esp when bought nib). The W-A system and location of the MAFs really kills the kit.

 

I've always had turbo builds and want to try something different. If I do go twin turbo it will be a custom set up. I won't buy a kit. When you really start thinking about how much it's gonna cost in the long run I should just save for a gtr but I really enjoy my g so until I can't say that anymore I'll continue to spend money and have fun with the car.

 

Alright I see. I was just wondering because the Stillen kit uses a centrifugal sc, so it's kind of like a turbo, but without the drop off. There's no power under the curve honestly unless you get the gamma kit, which is a rotrex sc. GTR would be nice, but that's a different story in terms of maintenance and cost of ownership lol.

 

I have a R2C2 intake, Stillen Underdrive Crank Pulley and a recent 3.69 gear install on my 2011 7at Convertible porker. My midrange is pretty lame. What else would you suggest I add before taking it in for a dyno tune? I'm really looking to improve the midrange much more than either the low or top end.

 

Supercharger will fill in that mid-range nicely.
