Jeff,

More practice and you will get 12's.

[Guest MFX_R33]

That too

Congrat's Jeff. Nice effort mate

Your new ET/TS is very simliar to my old times (13.1 @ 109.5 - 2.153 60ft) I had 215rwkw at that stage, once again similar to your 205rwkw mark!

Good luck with 12's mate. I've been knocking on the door for a while. Last s/meet, with the stock clutch finally replaced, I was very confident of a 12. But 1 pass (which I stuffed up) in 5hrs put an end to that.

Cheers,

Matt

Whatisname, that is a top effort. With your power you should be looking at mid 12's on street tyres, you just need to get the launch. I must admit, I cannot claim "full street trim" as I took out my subs, and spare, and set my tyre pressure dowm to 20 psi.

I have a 6 puck kevlar clutch, so that is not a weak point. I just think with a bit more practice launching, I can probably peek into the 12's.

Jeff.

Also whatisname, what turbo are you running/other mods to get that power. I am looking at trying to get a similar power level to you (I don't want to push the standard internals much past that). I am looking at possibly just getting a larger compressor cover and wheel, for my turbo.

Jeff.

I'm not really in the same league here...

I have an R31 with an RB25DET ... and a T04E ... and a few other mods zorst/short shifter/ecu

It's only running 9 psi and it pulled 190 rwkw on the dyno.

I ran it recently and i came away with a 13.85 @ 100MPH.

Could have been better if i could change above 6000rpm (as the fuel pump is on it's last legs and i'm not getting enough fuel up high)

Interestingly though... the 60' was 2.019 and that was with Simex 215/60/16 on 25 psi.

And as i've got no idea how to drive it'll get lower.

So i think 1.9 or better is possible with them.

Also a low 13 is coming (when i do fuel pump) but i'm looking into the cheap mods also, like pulleys and that sort of thing.

I've heard the pulleys are not cheap ?!?

I was also told the removing the Engine fan isn't good, and that the engine isn't happy ?!?! as thermo's don't keep it cool enough ?

Just a few things i've heard but i'm following this very closely as it's not just about power, it's engine ability to rev also.

R31Nismoid - that is a impressive 60' time. I'd be very happy with that... I think I might have to invest in a pair of these Simex tyres

BTW: I'm running a DC 16 thermo fan on mine now and it's great. Needle sits a fraction below half and has never gone past that. Car warms up quicker (great for the minus 10 mornings here in Canberra ), and the engine seems to have just a tad more responce.

I actually find that with normal driving the thermo fan doesn't turn on very much at all, and the temps are still the same as they were when I had the normal fan on. Sitting in traffic the fan will come on for about a minute every 3-4 minutes, and that was on 35 degree days.

I have a calsonic thermo fan

Is this a stock item on a R33?

I think my air conditioner thermo fan (the one that sits in front of the air con core) is a calsonic one.

If you've got a radiator thermo fan it'll be on the engine side of the radiator.

Thanks Jeff. Yeah it's just a matter of practice practice practice

Removing subs & doing tyre pressure changes, ahhh that's still street trim to me. Gotta' have the spare in though Need that weight over the rear end!

As with me, you've got the mph for a 12 no prob's.

I think we chatted re my turbo once before? I don't actually know what the exact spec's are unfortunately T3/T4 Garrett non BB built by Precision Turbochargers & not a high flowed stocky. That's about the only things I know 100%

Those are a nice list of mods you have there

I need to get my fuel regulator fitted and a new set of tyres before i go to the EC Drag Strip.

I was pretty happy with that indeed.

Little shocked actually as they aren't the widest tyres... and i'm not the best driver either.

They certainly aren't costing an arm and a leg so that's a good point also

mmm... My temp gauge just comes above the cold... right at the bottom.

The temp sensor has been chaged and it still sits Super Low and the car once warm doesn't run it cold start so it's a good level if you ask me.

Just don't wanna loose the super low temp by changing fan's.

I am sure we have but I have a memory like a sieve. I am very keen on going back down to Eastern creek again in 3 weeks. I have the bug now and I want a 12!!!

Jeff.

[ice180]

good luck dude unless you are using a safc-ii I've never seen a safc pull more than about 5-6 rwkw extra on a skyline... If it has been in conunection with other mods .. But if you get into the 12's great effort... no one esle has done it with stock turbo and intercooler...

Didn't the HPI S15 pull a 12.9 on the stock turbo?

[rev210]

The good ol' gtst would have had a 12 a while ago instead of a 13.4 if I didn't use little 205's. I don't care to stay in 13's anymore I've got a S-afc II and a cam gear on so it should be easier.

I wouldn't suprise me if the HPI s15 did 12's, they car is an easy one to get going quick.

[whatsisname]

The S15 is a bit of a hole shot weapon (for a RWD). Nightcrawler's S15 is a perfect example. Minimal mods (exhaust/FMIC), 1.90 & 1.93 60ft's on stock rubber, with stuff all drag racing experience! Nightcrawler's best 1/4 numbers are 13.4 @ 104 Hmmm? Strangely familiar?

Alittle off topic but anyhow....

For the people with traction issues, apparently the Dunlop FM901's are fairly decent. I got a quote today from my local Bob Jane T-Marts @ $265/tyre (Includes fitting and balanced).

Not sure if this is expensive or not (sounds it to me for a stock size) but yeah....

Ben - yepp, the 901's are pretty good. I wouldn't say they are the bee's knee's, but are still pretty good.

I've still got to watch first gear though, but that's more me being over zealous on the go pedal

One thing I noticed when I came up Macquire Pass (near Wollongong) is when you get a bit of heat in them they perform about 100% better. It's just a shame that they're not like that all the time

I got mine for $230 a piece for 225/50/16's, but they stuffed up the quote and they should've been $280 each .. Love it

[Xeron]

spend $350 a tyre and get some MT slicks, there a hard sidewall but itll still solve all ur traction problems. Unless u get axle tramp of course :

[rev210]

can't drive around on slicks.

Street strip tyres are another option. Don't think I'll need them tho.
