Well my numbers come from an actual drag strip ��.. Not some box you set on your dash ��.. But hey I have only owned a g35 TT coupe for almost 8 years and made over 100 passes on it, so what do I know :-) I just don't think a car that is 290 something hp can make a pass that fast :-)
But you own a G, I own a G and neither of us( even the owner of the car since it hasn't ran down an actual drag strip) know what it will do :-). Sorry you don't agree with my opinion brother ��..[/QUOTE]

I agree your point, that dragstrip give most accurate data. Technology 5 years ago was not so accurate as it is today. These boxes(not all of them) have been tested for years and they
keep developing. I have read that some car magazines use them for car testing. So they have to be accurate. Always is not possible to find dragstrip that would get best time thats why perf.boxes do help if they are accurate.Weather has huge impact on results. here is that car dyno:

 

That's pretty good for just bolt ons :-)). Who knows, I'm just going off what I have experienced with my g over the last 6 or 7 years :-) I do think sedans are faster and then coupes for some strange odd reason lol ��.. Take care my friend ☺️☺️☺️

 

Also i wanted to add, that if your G35 is TT it makes me wondering how your 1/4 mi is high 12'. When here is proven that G37 stock can drive 13 ' flat. Your G35 is more powerful than g37?

 

My G's bet pass was a 12.51 at a DA of about 6000 ft. Which would've been about 12.2 at sea level ��..

 

All the best to you also!

 

12.2 is pretty good time already but you still should be able pass 11.9 with nearly 500hp crank.
I remember new BMW M4 stock with 431hp drove 12.1 and with some tuning 550 hp crank
it pulled some 11.8 trap speed 125mph.

 

My car weighs 3860, and is an auto.. Maybe it was 11.90 at sea level? Not 100% sure.. I try to not over exaggerate ������..

 

It would've been
An 11.96 corrected at sea level ��. You were right
