The title of this post really summarizes my question, but to give you a little more detail...

I used to own a turbocharged IS300 that was done by Toyomoto in Miami and at low boost (i.e. 14 psi) I made ~400 WHP on a DynoJet. At that level I was easily pulling on 700cc bikes from a 60 roll (not condoning street racing, but just as a point of reference). At the track, I was easily hitting low 12s on street tires.

Now, let's look at the G35... I've seen alot of posts on Youtube where G35s claiming 400+ to the wheels are barely pulling on cars like E46 M3s and maybe running high 12s in the 1/4.

There is not a significant weight difference between the IS300 and the G35c, so why does the G35 seem so much slower even with the same power?

Am I missing something? I hope so, because if I'm not missing anythinig then I'm really discouraged from going F/I.

Thanks.

 

I can't speak for your IS, but a 400whp g35 should be running mid-low 12's...traction is the key, not to mention wheel size and weight...

 

400whp slow....nope unless you ahve a need for speed.

 

I wouldn't say it's "slow," but in a 3,600 lb car, not including the driver, it leaves much to be desired...once you've driven it for a while, it's really not that impressive...400whp doesn't do a thing for me anymore can't wait to get the new tranny and bump up the boost

 

You can't compare other times to yours coz they may have done it on a slow track, 90Cdeg temp + Humid, driver...etc. I say you drive it and compare that to your old time assuming conditions are the same.

 

I am running 13.2 on street tire, with ~300 whp.

If I have 400whp, I'd be in the 11". I think most
>400whp guys didn't have adequate traction. With AWD, traction
is not an issue on mine.

 

Ok I agree about the weight but at highway speeds the weight does not become much of an issue. How does it pull at highway speeds (i.e. from 60+)?

 

it pulls like a raped ape Go on streetfire and find videos of the speedometer of people doing 60-120 pulls...or better yet, find someone with a turbo G and ask for a ride

Don't get me wrong, it's fast...I eat M3's for lunch, but I guess I just got used to it

 

As a reference to the M3 rumor you hear of, I pull M3's daily and I am only n/a right now (not for long though ). M3's only run mid 13's at best with a professional driver, a 400rwhp g35c would annihilate an M3.

 

+1 I even beat M3's with just 4.5psi (305whp)

 

thanks for all your replies... i figured maybe there is some bad info out there about these cars....

 

Maybe so, I would trust the responses you get on this board besides from someone that doesn't have any personal experience with a G35 . A 400rwhp is not slow by any means, don't be discouraged to go FI with your G .

 

where exactly are you getting your info? ...and where are you from?

 

LMAO see my sig...hahaha

 

Yeah, the rumor of FI G35s hardly pulling on M3's is kind of out of wack. I run head to head with M3s (they take half a car by 100mph) and i basically only have a intake and exhaust with a tune.

I know the stillen stage 1 SC is a load of crap for our cars - and still runs mid to low 13s, but any other application with a decent tune is going to run mid 11s to mid 12s depending on boost.
