So close, Low 13's Again!

[Guest Robo's]

Just came back from a Test N Tune day at Heathcote and heres a listing of my runs. I thought a 12 was on the cards but i just couldnt hook a good 60 footer. I found the track to be quite slippery. I tried my best for a good launch, low tyre pressures, good burnouts, but just couldnt get strong grip. It might be time to turn to some stock suspension and get some weight transfer on launch. Teins dont give much.

13.099 @ 104.92, 2.09 60'

13.140 @ 105.46, 2.13

13.16 @ 2.12 (No Time Slip)

13.253 @ 107.78, 2.17

13.283 @ 105.36, 2.19

13.297 @ 106.38, 2.16

13.337 @ 105.34, 2.27

13.404 @ 106.99, 2.15

The quickest time 13.09 was the last run of the day and was pinging badly at the top end, hence the slow terminal speed.

Good consistency

You're doing better than me, best mph of 114.6 but best time of 13.077 (@113.36mph, 1.999 60ft).

I pull constant low to mid 13's with my R33 GTST, using a FMIC, Stand alone ECU, Stock Turbo, 10psi. 178rwkw

Track temp was 26-28 degrees, 60ft times around 1.95 - 2.2 depending on my launch and wheel spin.

Well you did better than me too!

my R32 GTS ran 13.5 @110mph, but with my crap tyres i couldnt get a 60ft better than 2.3

what rubber are you running?

[Guest Robo's]

Sumituno's HRZ2's, they generally stick well on the track but for some reason i was really struggling. I have runs before where im in the 1.9's and constant 2.0's.

Next tyres will be some sticky rubber, ie RE55's, or the new Toyo Proxies. Guys running these are getting 1.7's even some 1.6's.

jesus 1.6 is better than some guys with 4wd !

i have a gts4 and the best 60ft i've had is a 1.8s

well done on your times though ... you're not far off that 12 now

[bbenny]

wow those toyo's sound good, ill have to do some research on them.

are you talking about the proxies RA-1 or T1-R passanger?

your 60ft times sounds pretty good though, i would be happy with a 2.0 or anything under.

i found that my only problem was just getting traction. mind you i ran on 205 continental crappies. what was your 60ft for the 13.09?

[aridyne]

There are also many variables, not just tyres.... I had only 15% tread on mine with a crap clutch. This is when I was getting 1.9s on the 60ft .. 235/45/17 running 28psi Tyre Pressure and dropping the clutch at 2500-3000rpm.. I think it also depends on the driver and how well they know they're own cars limitations.

[JH32]

The Proxes R888 is a street-legal race tyre recommended for competition use. The Proxes R888 has a low-void ratio for minimised tread squirm on dry tracks. The new groove design optimises water drainage from the contact patch.

So they are a competition circuit tyre of the same vein as Bridgestone RE55.

Congratulations, im sure you are good at lots of things...

Im not saying it is the only variable, but i am curious to see what type of rubber people are having success with other than Nittos and BFGoodrich.

Robos is pulling some awesome 60ft times, so i dont think we can say he cant drive.

yeah i am reading up on these tyres now, they sound pretty good, just called my local toyo dealer - bloody useless couldnt even get me a price on any of their motorsport models...
