Hi i have a situation that i hope you can help me out with.

i had a race today and lost to a GTR about 2-3 car lengths

i have a GTST with a fully built motor and all supporting mods. except for coils witch is limiting me to only 12psi. Anything over that and i get a bad misfire. (new split fire coils are on the way.)

with only 12psi I'm having a traction problem and need better rims and tires.

i need a set of drag rim's and tires, size about 15x11 inch wide for the rear x2 . and one of the best drag tires on the market.

the car is about 750 hp. can any one help me with the offset that i will need or anything that can help in this situation.

gtst+standard coilpacks+12psi = 750hp= 559.27kw hard to belive

No mate using a friends coils i was dynoed at 750 hp at the wheels. i'm limited to 12 psi with my coils as thats the only thing on my car that is stock.

this hp was at 30psi .

running 12 psi I'm ripping loose BF Goodrich full drag tires on 17's

i used my friends coils to find my problem the coils are braking down slowly first it was 20 psi them 15 now its 12 with a .6 mm gap this is crap

i need a full drag set up.

What offset can i use on my car (GTST 15x11 wide with Mickey Thompson drag tires ) please help

I doubt you'll find anything in 15 x 11" to suit a Skyline backspace and even if you could, you'd struggle to make it fit under the standard guards. If you're turning 17" drag radials to shreds then just get full slicks. I reckon the biggest you will fit is a 28 x 9" slick and that will be far from easy.

Mate, have you given any thought to your suspension? That level of power to only two wheels is going to give any sort of tyre grief. I would be looking at your rear end setup before tyres. Suspension can make or break a car. :D

thanks mate so how about 15x 9 or 15x10 the most. OK lets say were going to use 15x9 what would you recommend (witch tire brand

and type.

the last person that replied said i should think about my suspension. i have a set of coil overs, thinking about it that's not a drag setup.

can anyone recommend a suspension set up for this GTST.

Just out of curiosity have you ever tried taking out the coil overs and having a go with standard suspension ? Coil overs are generally way too firm, specially if they are in the car from Japan. Those guys love using spring rates on the street that really should be track only

thats od that you say that, i was thinking of the same thing. before i put the coil overs on the car felt like it lunched better with the stock suspension. i think this has to do with the spring rate like you mention and the travle the car should scwat better off the line and in gear changes with the stock set up.

I was thinking on contacting the guy at titan motorsports and asking some question on the setup i should be using.

there always battling GTR and should be able to help.

do you think 15x9 rims with 28x9 mickey thompson full drag tire would fit on the GTST.???????????????

I realize its pretty obvious, but if you haven't already get a set of pineapples and adjustable rear camber arms. Its not going to matter what tyres your running if you've got -5 deg camber.

i'm new into the drag world i dont know what a pineapples is.

the adjustable rear camber arms i know about and will buy them asap. with the arms your saying to run the rear wheels at -5 deg camber.????????????right.

what is a pineapples ?????????/

      He made that comment in my thread - In my case the vents ARE to lower engine heat, when the car is not moving, which is the only scenario I have heat problems with the aircon on, sitting in traffic, on 40C+ days. I can't imagine a scenario that this NC needs any at this point in time. I do not know if it will actually make my cooling when the car is MOVING worse, and I sincerely hope that won't be the case. If it does, well, um, f**k.

      Nice, thanks. Thats why I was asking, there'd been a fair bit of discussion in the E90 world about vents and where it makes sense to put one (ie, over the filters is not great as that is inline or slightly behind the struts and in higher pressure area). I struggle with air flow and pressures. It sill weirds me out that a radiator in the boot can work.

      Neither really Vents, when located in the right place, will lower the engine bay "pressure", as air has a path to escape, thus lowering the engine bay pressure, thus.....improving the efficiency on the coolant stack (read: IC, condenser, radiator) This is why the Blits vented bonnet on my 33 worked so well, the vent was in the front 1/3 of the bonnet, which put it right after the radiator  If the vents are to far back toward the windscreen, which is a high pressure zone, it can actually force air into the engine bay, causing higher pressure and effectively loosing efficiency on the cooling stack, like the fab of raising the rear of the bonnet, which does allow heat to escape, but only when the car isn't moving  There's heaps of cool "fluid dynamics" info out there, but, I'll attach a video of a 'Merican joint that focuses on "Miatas" as I found it when looking into vents for mine, they explain it way better than me

      Poor bleeding. That stupid damping loop in the plumbing that should be completely replaced with a braided hose. Just the first 2 that come to mind.

      Forgive the potentially silly question but are the vents for bay temps? I've been toying with how to reduce my bay temps because man, it gets HOT in there and a small subtle vent somewhere I think might help. Or, maybe they're to assist with just the intake temps?
