just got back from the 1/4 track...

[T2urtle]

i'm just reporting what they told me and what i saw with my eyes. all 3 were running VF39's are in the mid-low 14's

question... i have my set of forged 18's and soon to put summer tires on it but i was wondering if it would help me be quicker not tire wise but just based of weight.

stock 17x7 rims run about 23.5lbs
forged 18x8.5 run 18.6 lbs

215/55/17 tires should be about 21-22lbs
245/45/18 are 24-25

So really i might shave like 2lbs off each corner. But i was told bigger wheels no matter what will slow down the car, i would have more tire surface and hopefully i can hook better off the line. I'm not going with really sticky stuff like RT615 but more like Hankook V12's or sumitomo HRZ3 tires shortly.

Oh I'm not saying that's not what they ran...I'm just saying that I'm pretty confident I could run that with my 100% stock 104,7xx mile FXT.

You'd take a 1.4% hit on gearing with bigger wheels. If you're losing 2lb/corner, I think you'd be better off with the lighter ones.

 

[T2urtle]

yea i know about the 1.4%, stock size for that 18's are 235/45 but the selection on tires are just horrible. like 30 tires on tirerack and similiar prices. VS 245/45/18 which has like 150 tires. i figure maybe a little more tire wouldn't hurt.

 

[jlee]

Have you looked at different 17's?

 

[T2urtle]

my stock 17's are going to be my winter wheel setup. Once these all-seasons are done most likely next spring. These will have blizzaks on them.

I picked up a nice set of forged ray's 18x8.5 mainly because i liked the offset and lightweight overall, plus tires for 18's are a lot cheaper then 19's which everyone seems to get with the G35. I really do want to run my 18's with a 245/45/18 setup, so i'm pretty stuck on that. The tire brand i can change up. But after all my research for the $150 ball park Hankook v12's or sumitmo HRZ-3's are the best bang for the buck. Since the dunlop stars specs are in the 200$'s and have a lower treadrating.

You're complaining about only 30 tires? I run 285/60R16s and currently there are TWO! The stock size for mine (255/65R16) only has 30.

Heh - if I search Tire Rack for matching front/rear tires for my MR2, I have one option. :/

I'm pulling 1.6's in a RWD car, an AWD should be easily capable of a 1.7.

 

[thescreensavers]

If you did an AWD burnout to warm up the tires before the run you would be in the 13s, otherwise it looks about right.

Yea umm thats for Drag Radials, he is on street tires, if you did a burnout on street tires you will actually get less grip, a quick turn of the wheel to clean off debris is all you need. Plus you cannot AWD burnout the tires on the G35x.


The AWD System in the G is not active until it detects the rear slipping then it sends power to the front. And its only up to a certian speed.

OP a 14.8 ish is a good time stock for AWD and you hit 14.5 -14.9 most of the times, you have more weight then a normal RWD model due to the AWD stuff, your time is good for your first time. The next you go hold the brake down till 2.5k and turn off the Traction Control, and you will see your times will get a little bit better.


Also, personally I wait 15min + between runs for things to cool down.

here is a run I did it was very hot and so I only did 1 run, http://www.youtube.com/watch?v=idrY_REkvT0

I hit the limiter from 1st> 2nd bleh lol, and damn Turbo Diesels.

btw, people telling you to leave it in Auto and not to brake torque obviously never went to the drag strip with a Automatic G.


Here is a G35x in the snow, look how the Front wheels engage after the system detects the rear slipping

I already was doing that. some runs weren't at 2.5k and some were, all pending how much time i had at staging. VDC was never on, if it was on that would be like 16's

 

[Demon-Xanth]

Heh, the truck in that vid redlit, but ran 13.73@102.53.

 

[thescreensavers]

^ Yea they are stupid fast in a straight line lol

ok cool so you were doing what you were supposed to, next time you should get a bit better times since you will have more experience., your spacer does not really add any time it all beyond 3 digits lol. Combines with other mods and a tune would get you lower. But imo its not worth it.

 

[T2urtle]

not worth what?

assuming my 14.5 was an error all my other 11 runs went from 14.7- 15.3, i just want to narrow that down to maybe a 14.7-14.9, just gotta keep practicing i guess. but i wanna know what i need to work on. Obviously from the slip i need to get my 60' down a constant number or somewhat the same. All i want to know now is how to get this the same.

I just read FSM stall speed is 2300-2600.

 

[thescreensavers]

If you wanted to spend a more money on other NA mods, I would say its not worth it. Unless you go for it all which is a lot.

Yea umm, I wasn't serious. Thanks for playing though!

 

[Viperoni]

Knock and oxygen sensors in good shape?

 

[T2urtle]

no real way to test it, other then no CEL and no issues driving to indicate otherwise.
