Doing The 1/4 Mile, What Times Should I Expect?

[Marko R1]

hi guys,

im running my r32gtr, has 325awkw on 1.35bar (street tune)...what times can i expect to hit?

what else do i need to do to prepare the car? (this is my 1st 1/4 mile run)

my tuner recommended i run octane booster then i can run 1.45bar boost, on 1.35bar knock level doesn't go above 25 so its nice & safe

how about tyre pressure what should i run & will i need to do a burnout to get the tyres sticky?

my guess is that i dont need to worry about these 2 things being an AWD...

regards,

[cheez]

depends wat ur chasing i guess... a street car set up time or a race time.

if u wanna know what sort of time u can do on a street you have ur tyre pressure at street pressures (about 32psi) and have just standard 98octane fuel. and thats it.. should see mid-high 11's.

if u want a race time, tyre pressure at about 22psi and run the octane booster and take out your headlight infront of the pods to get more cold air in and u should see low 11's.

also depends on how u drive and ur ability. its critical on gear shifts and how u get off the line. but after a few runs you'll find the groove and feel more comfortable launching in a race environment.

Low 11's

i did 11.4 and didnt let out any tyre pressure or really worry too much this was with r compound circuit tyres.

wouldnt worry about doing a burnout if your on street tyres. as i doubt it does much at all.

other than that

do a good launch! and you'll be set.

what is a good launch? ive done 5000rpm & its nice...ive also tried around 6000rpm & it goes ballistic (u can smell tyres frying all 4's)

4000rpm & it gets boggy...

changing gears fast & clean would be important but not flat changing right? i dont like hurting my car

would i be dreaming to think i could get an 11sec pass with 310awkw r33 gtr in full street trim minus spare tyre?and toyo t1r street tyres (non semi slick etc...)???

thats a nice time - what power are u running to achieve this?

[paulr33]

dont bother with octane booster, run 100ron if you are worried about knock

drop tyre pressure to 20psi and get your time slips, they are good data & help plan improvements

then head off the drag section on the forum and read read read, once you have done a few runs and got some time slip data

this would have been done on my shagged turbos (most of the front wheels were missing) which made about 400hp.

also i have close ratio r34 box tho this didnt really help my 60' times at all which were around 2.1 tho it helps with the abuse.

i think i did around 6000rpm using handbrake to hold in stage while i reved up and engaged the clutch and off i went.

[R31Nismoid]

low 11's at least.

You can get mid-high 11's with stock turbos as it stands, so add on another 40rwkw, expectation says low 11 without much drama

moved to "drag" section also

[GeeTR]

Hot R compounds + 7k RPM dump should see a 11 with eaaase i would have thought... assuming your clutch or box doesn't let parts out.

"R Compounds" and drag racing don't go in the same sentence together.
