Goal of 13.5 sec 0-400m - Advice

[Robo]

Hi there,

Ok I currently have an R33 gts-t ser 2 with the following mod's:

-Boost set to 11/12 psi

-CAI with Pod filter

-Full 3" exhaust (one piece front dump from turbo, hi flow cat and the trust cat back exhaust)

-Oil/air seperator

-Font mount I/C (Apexi Hybrid)

-17" 235x45 front and 17"255x40 rear

Should be about 180/190 rwkw's.

I guess my aim is about a 13.5 second run 0-400 meters. I am not looking at changing injectors or internals of the RB25det.

To me the car feels average (because I'm so used to it...).

I would like some advice from those out there that were in the same situation or know about this.

Should I go down the path of getting the turbo high flowed and replace the shafts with steel units?

And if I did this will an SAFC work well?? (don't really want an power FC)

Keep in mind I don't really want to totally change turbo's or waste too much money.. The most I want to spend from here is about $2K ($500 for SAFC and $1500 for hi flowed turbo).

Can anyone also tell me what sort of rwkw's I could get from the above? And will this help me net a sub 13.5 second QTR mile run?

Thanks for your help

yes it will do around 13.5-6, just get a good launch

around 3500rpm++

[dojobi]

Really? That's good to hear. I thought my car was only good for about 13.5s too, and it's been setup as above, but with a cam gear and SAFC.

BTW Shuto, out of curiosity, how do you know your R33 is the first gtst?

[dojobi]

Robo, I'd say you're not at 180/190 rwkws, probably more like 160-170. I'm at 177rwkw (measured at Hills, non shootout mode) with a SAFC and cam gear on top of what you've got (except for the oil/air separator).

1st version:)

the fastest gtst i seen with stock turbo, but had a power FC was 13.3

yeha robo an s-fc will help you achive what you want with out problem provided its tuned correctly the rest is driver skill

my car runs a 13.9 only got cat back zaust, 11psi, pod, safc

im sure urs would be able to do round a 13.5

Forget launching at 3,500rpm.

If I launch @ 2,000rpm my car just wheelspins and then drives off, If I launch at 2,500rpm with a full car load - (200+ kg's extra over the back wheels) it sits and spins even more.

I find giving it about 1,500-1,700rpm works best for me (but then again my tyres are sh1t).

Go grab yourself a fuel regulator and an exhaust cam gear and give it some more tuning and you'll crack the 13's.

[rev210]

I drop the clutch at 3000-3500rpm and 'feed' the throttle.

If you get into 13's then you can be happy, most perth gtst's can't manage 13's.

Go to the drags and see how you go.

[meggala]

funny that rev plenty in melbourne get in to the 13's on our crappy track

[macka]

I wonder how much the tracks do differ?

My bet he would get 13.9 with those mods and not much more....

Id guess pushing 160rwkw

All u can do is prove us wrong eh...

[Robo]

Thanks for all your reply's.

Just wanted to clarify a few things,

1) Some of you say it is possible to crack a 13.5 (taking into consideration driver skill), Is this with a high flowed turbo and SAFC or with what I currently have?? (should I just get an SAFC and leave turbo?)

2) Has anyone actually high flowed their turbo (and replaced shafts with steel unit's)? How successful was it?

At some stage I will go to Eastern Creek for a run (never done it before... should be fun).

Thanks

Rob

You won't need to hiflow your turbo to get into the 13.5's

[macka]

Hiflowing a turbo is a touchy subject

There are multiple threads on this so im not going to input much

But i can say it has its benefits over expensive non bolt on units..

[rev210]

I've got a consistant 13.5sec car and I didn't have a hiflow or a S-afc to get there.

I'd forget about the guessing and go hit the track. You will need some experience to make the most of any mod when it counts 1/4 or otherwise. Besides you go down to the track to have fun, not to show off your times (you do that when you go home and post it on the forum ).

[macka]

But rev your a freak

[benm]

a freak with many pieces of paper

[Robo]

Once again thanks for the replies.

this may be a frequent quetion, but what is involved in running down the Qtr mile???

Are there any days where the strip is just for Skyline Australia members etc.. (EG. Dyno Days) that get organised?

I would love to take it down to Eastern Creek and try my luck... Can anyone tell me if there is a specific day (like every month) that you can run your car or is it every night.. etc..

also is it any different launching on a drag strip to street??? I've heard tyres stick better to a drag strip...

Thanks

Rob

At Eastern Creek they have off-street drags every second wednesday. The track does have better grip because

- the track is warmer from the other cars that have raced before you

-your tyres can be warmer cause you can do a fully sik burnout as you come forward to the christmas tree lights

-and finally the EC staff put some crap on the track to help it grip more so yes you can launch a lot quicker on a track than on the street.

OK as for the actual Drags, you need to be there between 3:00pm and 6:50 pm to be in for the drags that night. Its $45 per driver and $35 for the second driver if you have one.

Its on the second wednesday of every month and a fornight after that.
