What year is this car btw? My G got better numbers than this from the factory, and to go from 300hp at the crank to 200rwhp is quite a dive...unless this is one of the old G coupes...but still...seems like something's off. ? Plus, I've read so many posts about this exhaust setup getting 10hp over another high quality aftermarket exhaust. Just seems like a lot of money spent and stuff done to get just under the point an '06 or even '07 coupe begins. It says the baseline is bone stock though...so if this car is like pre'05, and that's why those numbers are what they are, and you've been driving this car all these years bone stock, then you must really have enjoyed the new speed and sound you got with all that stuff. :-D Congrats
My best friend has an '05 M3, so when I bought mine (I lucked out...they were cutting like $5-10k off when the new style G37's came out, and I liked the G35 6MT's better anyway...the new ones are too big and cushy...i like the sportiness of the G35s) I had to change some stuff right away, lol. I didn't play stock for long. Ironically, he's all pissed because mine sounds more deep and exotic than his, and starts really pulling ahead over 130mph. I dunno how u resisted for so long, but..enjoy! :-D

 

My car is an 2003. I'm not too concerns about the actual max HP and TQ numbers since all the Gs and Zs that go on that Mustang dynamometer gives out very low number. What I'm concerned and happy about are the gains from stock. However since I am getting my cams and headers installed at a different shop, I will also get new dynos on the more popular and high reading dynojet.

 

The exhaust system is the Motordyne Gamma Dual Exhaust with a resonator at the end of the XYZ pipe as oppose to the straight pipe.

 

do u have any sound clip?

 

holy thread revival! Always wondered why the g37 got no love

 

Here is the video with boltons


And here it is with the new engine

 

Damn, that sounds sick. The new engine made that big of a difference?

 

Yeah. I should have clarified it a little. The new engine is a built longblock with higher displacement and compression. I've also added SGM long tube headers. So the combo of all those made the difference.

 

What's your idle at in the vid? Sounds like it's higher than ~650.

 

~1000rpm

 

made a drive by vid, it sounds beast

 

^thanks,

Here is my cat beast meowing down the road

Very nice.

Thank you sir

 

The cams really make it sound nice. Almost sounds like a cammed LSX.
