[R33GOD]

hey guys/gals im wondering how much rear wheel kilowatt do u need to achieve a high 12 second pass down the 1/4 mile in a r33 gtst?

im curious to see what ppl come up with cause i have no clue.. i know the driver plays a big role too.

if u can guys plz post your times with the power you made at the wheels

cheers

200rwkw

drag radials

suspension work

prefect launch

prefect conditions (high track temp)

250rwkw

drag radials

suspension work

ordinary launch

good conditions

Pretty much spot on

But if you cant (as most people on a budget cant afford em) buy drag radials, make sure you set your tyre psi much lower then normal.. I think around 20psi?

Also, remove all the rubish that will slow you down, like subs, amps, spare tyre (leave them in a mates car just incase you blow them), rear seats (for the wank factor), ect ect..

230-240rwkw R33 Gts25t (Moanie)-MONA!

Consistent MId-High 12's

Monster Burnout

Stock Rims, Street rubber

Good Launches!

Other Specs Unknown.

This Gal can DRIVE!

in your 1400kg car ? 220rwkw, decent 265 rubber and the ability to use a clutch should get you there.

175 RWKW on street rubber at 18psi will be enough with <.2 R/T.

[paulr33]

reaction time bears no relevance on the 1/4 time

you can have a 20s reaction time and still run 12s

[Kennedy]

woops. wish i knew that before. Oh well....guess its good practice for grids one day

i would add to the list good lsd (1.5 or 2way) i found i have alot of problems due to my stock lsd being worn. power to 2 wheels beats power to 1 wheel

My post is based on times i've actually run in my car which is the same as the one in question. I have seen absolutely no reason to upgrade a diff to achieve these aims.

112mph wih 251kw and 13flat 1/4mile time

reason y im asking this is cause my tuner thinks i can only make 210 atw if im lucky due to my mods.. i thought i could make more tell me what u guys/gals think?

pfc, fmic, hiflow turb, stock injectors, 040 f/pump, 3in turb back exhaust w hiflow cat, k@n pod

car has been lowered from japan but there compressed springs.

True. If you're diff is open-wheeling (spinning one leg) then it should be repaired or replaced. Fair enough.

it's your injectors that are gonna let you down. All the other mods can get you to 250RWKW. The standard injectors run out of puff at around 210 to 220 max. CAMS, injectors and Z32 AFM will get you to 250 easily..........dependent on the quality of the hi-flow

[paulr33]

you can get to 250rwkw ish with stock injectors & fuel reg

its the sliding hiflow that ive got.. how do they compare to say GCG?

i only bought it cause it was cheaper and has to be better than stock lol

[CEF11E]

I am making 238rwkw on the very same turbo but it is only bolted to a RB20 with an rb25 260rwkw is realistic

[2rismo]

Someone tell me where you need 250kW to run high 12's?

[BAMR33]

Some one told me this dunno if it's true 'cut the standard springs get them tempered softer and fit to standard struts' allows the car to get better traction off the line or something.
