looking for info from anyone whos raced down the strip

[SLY33]

hi guys, planning my first run down the strip this wednesday at WSID.

my question is about how much fuel to run with. there's a fair bit of difference between a full tank and half a tank of fuel as far as weight goes (perhaps 20kg?). im thinking that having less fuel will help my TS, but then again on the street a full tank of fuel helps get off the line. I hear the strip is much sticker, but how much? If i launch at 3grand on the street, how much more can i add at the strip? -so far all ive done is take the 2x12in subs out, which together weigh about 25kg inc boxes.

note im running on 19in street tyres.

thanks all.

As far as weight saving goes, dont forget to take a crap before the run.

Why not try asking this question in the Drag section?

As a matter of fact....

Half a tank will be fine. You don't want too little or it could get bad, quick...

Remember, if you intend to run on the 19's, let some pressure out of them before you run.. Try about 20psi LESS than what you usually run.

So a search for a beginners guide to drag racing on this forum and see how ya go. Better get there early this Wed as there's only gonna be about 80 cars aloud to run due to the burnout comp.

Good Luck!

a drag section! funny i never noticed it, only ever seem to be in general or forced section.

yes tits i dont plan on running with a full bowel. That will save a couple of kilos

ive asked about tyre pressure for 19's in another thread but i cant find it, and cant remember what the conclusion was, but can anyone tell me from "first hand" experience if dropping pressures in very low profile 19inch tyres will actually make a difference? I think that even if you drop pressure, there is still hardly any sidewall to flex to get benefit from? not that it could hurt so im likely going to drop them anyway.

Adrian, ive never been to one of these burnout comp/street meets, how early would i have to rock up? gates open at 3 i think, i was gonna try to get there by 1? and is it worth going to race while they are having a burnout comp on the same day?

thanks

I dont think I'd worry too much about the amount of fuel you've got (performance wise). I usually need 2 passengers in my car before I notice a significant drop in performance. Last time I went to the track I used 1/4 tank to drive 4 miles!! Make sure you have enough :uh-huh:

Altho I've only ever run on 16" tyres, letting then down is certainly the way to go.

Launching is up to you and how much power you can feed to the tyres without them spinning. There is no "rule" as to what rpm you should launch at, just remember that high revs = good revs. Your mission is to find the point between 2500-6500 where the wheels dont spin, then feed it more.

Let us know how you go

Last time I run at WSID. I had under 1/4 tank and the car picked up an extra 2 mph TS

Maybe I was just driving better on the day. See you there this Wendnesday

[Mandingo]

If you have the stock wheels, put them back on. you will launch way better. good luck

congrats sly33 on a great run last night, 13 flat almost wasn't it ???

had everything well under control from where i was sitting

To begin with I was removing everything lose except me and the seats... sub, glovebox stuff, center console stuff, jack, spare tyre etc and I was running on about 10-20L of fuel.

Now I leave it all in and use 20-30L of fuel so probably about 25-35kg difference (half a passenger).

The difference I have noticed is no axle tramp with the extra weight in the back (tyres and tyre pressure have stayed the same).

Next time im out on the track I hope to have:

* Semi-slicks

* A clutch that releases and engages gears

* Brakes that work :Oops:

If all goes well I might start removing the tyre/jack/sub.
