Can Some One Help?

[yogibear]

ok been to eastern creek 2 times now with my gtr , 316rwkw @ 16psi from a to4z (stock head so very lagy)

this is my times so far all on falken 235 / 40 /18

12.512 @ 112.77 mph with a 1.789 60 footer

and

12.394 @ 112.84 mph with a 1.842 60 footer

and last time i went down my best time was

12.302 @ 114.47 mph with a 1.849 60 footer

ok my question is can i get faster with my current setup?(with out going to other tyres)

thanks heaps

times are close to where you would expect them with your current power and sixty foot times.

tyres will improve your sixty foot time, and run if your currently getting wheel spin.

i ran 11.36 on stock turbos, stock head, 290rwkw, 265 35 18 tyres and 1.7-1.8 60fts we talked atthe track the other night and i said then you should put on some cam gears and get them dialed in it will help reduce your lag and setting them up don't worry so much about hp as it means very little aim more for as much low end torque as you can get for you current set up, your 60 fts are ok with the tyres your running you need to get more mph

125mph ??? thats 500+ rwhp trap speed..... were you able to repeat it (not necissarily the 11.36, but moreso the 125mph) ?

[Marlin]

LOL, no way!

wayyy back in 2002 I ran 11.13 @ 128.5 (1.82 60ft) on a stock bottom end with Apexi low mounts and other little odds and sods.

315RWKW.

New owner in Tassie re-tuned it and went 10.80 at similar mph.

Maybe they were really really big killer Wasps?

They were Qld ones after all, our are bigger and stronger!

[zebra]

I hear that European killerwasps are the biggest and baddest.

But I think it woul dbe the lag that is killing the times though, all very well that its making 300+ but no good if it is only in the last 1000rpm.

[Marlin]

True true..... swhy I no like big laggy turbos...... wait, I have one on the way for the 32 now. Dang!

[R31Nismoid]

125mph = 370rwkw+ in a 32GTR???

Friend of mine went 127/350rwkw - R33 GTR.

I have around 350rwkw apparently, and @ the strip in a couple weeks. See what MPH it runs but I'm expecting around 127-128 as well

[Beer Baron]

I think the MPH is below what it should be with a genuine 316kw. I've run over 112mph with only 250kw and ran low 12s about 5 years ago with stock engine and stock turbos @1bar.

60ft is not bad, but the fact that you're only running 112/114 mph means you are down on power. to get into the 11s your going to need a fantastic run or more power. either that or the power deliver is really bad. but with 316kw you should have higher TS than 112mph...

[yogibear]

the car is booked in to get cam gears and surge system so i can actually run more boost.

XKLABA did u happen to get what the std cam's are meant to be dialed in at yet?

and as for lag , i don't get full boost till about 5000 too 5500rpm so yer it is fairly lagy

[yogibear]

and i only rev it too around 7500 rpm

[Strik3r]

I have a genuine 500rwhp (closer to 540 actually, but lets say 500) and I did an 11.5 @ 126mph. Spose the 32GTR's weigh a bit less. Those online calculator thingies tend to agree with me though:

Vehicle Weight

In Pounds

3250 (1475kg with fuel and driver)

1/4 Mile

Trap Speed

in MPH

126

Your Rear Wheel

Horsepower

is: 507.3964497041419

Which is pretty close to what my dyno says.

If i change the weight to 1425kg for a 32gtr with fuel and driver:

Vehicle Weight

In Pounds

3141

1/4 Mile

Trap Speed

in MPH

125

Your Rear Wheel

Horsepower

is: 478

Still a lot more than 290kw...

Meh, you have the slip that says you did it. Kudo's to you. Maybe you guys are all skinny bastards and are better at stripping your cars out than me

[R31Nismoid]

I've never truly believed those online calculators. Rarely are they totally accurate.

A lot of things like diff gearing, how many gears you are changing and so on all have effects in various ways, even rim size.

I also know of two friends in stock turbo R32 GTR's that have run 11.5 and 11.7 respectively - no idea of MPH - They surely cannot have any more than 270rwkw either way.

The 11.5 was driven without one iota of mechanical sympathy (flat changed etc). 11.7 was a bit more forgiving.

Just for info sake - with ~210rwkw I was regularly running 110-112mph (2.0 60ft/RWD) @ Calder in my HR31 back when i raced regularly.

Car was just over 1400kg without me in it and under half a tank of gas. So would have been 1500kg on race day (roughly, car was never stripped)

[Bunta]

the calculator I found says with exactly 400hp to the wheels I would do 124mph, I used the same weight you specified too Gerv. maybe every ones calculators are a little different

[benm]

Your problem is the first 60ft on the track, forget about more power etc etc get the factory rims and some MT drag radials and watch it do an 11.9sec

[Beer Baron]

I still think the low mph is telling us it's down on power. 316kw should give a fair whack more than 112mph.

btw most GTRs with fuel and driver will be much heavier than 1475kg. regardless of 32/33/34 none of them will be under 1500kg with fuel and average driver unless they have had some weight reduction done.

[NXTIME]

Yep, the 60' times are usual for street tyres, but as mentioned above, its the trap speed that is down. You may well have 316rwkw, however, that isn't being reflected in the trap speed, and this is were the issue is. better rubber might get you an ET in the high 11's, but the MPH doesn't lie.

yea sounds like more like 250 killer wasps#

even with 3k rpm you should be charging hard to4z styles

#i have only ever done 4 drag races, check my sig apparently that dude knows how to do it

[Beer Baron]

yeah my old grey GTR ran over 112mph with about 260rwkw consistently.
