Drags 19th Feb 03

yeh well hopefully by bringing down the exh housing i will see a wider power band and more usble hp. which should convert to some decent times

14.4 is my best so far at 109mph

its got loads of power over 5000rpm but thats really not impressive except on a dyno

im in the process of rebuilding it, and putting a smaller exhaust housing (0.63) on it. which should help things a bit, anythings better than the 1.06 ive got on there now!

Adams car is built for drags but it needs cams and cam gears and a computer that can take the Revlimit up to take advantage of the high spool up should be good for low 12s but anything under 14psi and it doesnt work

Yeah, that 109mph is about what Macka is doing his flat 13's with. I would think traction would be more of an issue, as once your in the power then there should be no need to move out of it. Even if it is laggy, if you launch hard enough then you will always be in the power.

Yeh, you'll be in the power for how long, 2000rpm, then revlimit. A bit of a shame!

Adam - who's decision was it to put that massive snail on it to begin with ? came with it?

why would someone do such a thing, any real reasoning ?

[GTS-t VSPEC]

Even if you only have 3000rpm of on power, then with hard shifting then you shouldn't step out of this power band.

Hopefully with a better choice of exhaust housing then you will see that power for much longer.

Cant really compare v8 mph and times with turbo 6's specially with slicks autos and all that stuff.

The key is the launch in both though, the turbo willhave less mid range though and are usually not built to be sole drag cars.

My biggest problem now is clutch. 1.9s are possible but the clutch slips by 3rd gear.

It doesnt really matter where boost comes in on the dyno

cause unless your lusing boost between gearchanges, you wont get lag

[GTS-t VSPEC]

LagWagon,

Have you tried a twin-plate yet, I find mine very easy to drive and they should last your longer then the clutches you've been using so far.

[macka]

We are hoping 3500RPM

Strich9 it came with his car, nice turbo unfortunately not much good with his current setup with only 14psi. Reasoning as i said b4, cams gears and comp. will help powerband last longer..

Paul, Flat 13s were done @ about 112mph

I was getting 109mph with 13.5 area

[adam 32]

the car comes on boost hard at around 5000rpm. with a brass button clutch and low profile tyres try getting that off the line!

its a drag turbo, but nothing else in the car is setup for drags! ive got stiff GAB adjustables just to make things worse

moral of the story, ditch the big bastard and go for something a little more streetable

[GTS-t VSPEC]

5000rpm, that is very late, must be a bitch on the street, most things will beat you off the lights, until the turbo kicks in.

Brass button clutches are nasty for doing a decent launch, ask RB20LagWagon. I'm driving with a 4-puck at the moment, can't wait for my twin to come back.

The big laggy turbo's are what all the japs use, but they are able to launch off the limiter and still get traction. A smaller turbo with streetable power will be the best of both worlds.

[adam 32]

yeh theres no boost whatsoever in 1st gear until about 6000rpm

hahahah its actually laughable. you should see my power curve!

[GOT BOOST]

i got a 2.0 60ft lastnight i think the new GAB's.

made the difference (cheers Radium)and thats on Simex tyres.

[GTS-t VSPEC]

Adam,

So what revs do you launch at?

[OptiC]

hmmm problems with the movie .... i'm guessing it's something to do with the program you use to open the move it has to be quicktime for the fact thats what my camera encodes in so every trying to watch it using windows media player as much as you try it wont work

i'm not sure how big quick time is but i might be able to up load a useable down load if not you can get quicktime player from there website

ok well it's a 7.4mb or there abouts ziped installer but it's worth getting for all you lucky people that have ADSL it's about a 2min download

www.westnet.com.au/optic_4ce/QuickTimeEnglish.zip

or you can go to there web site hunt around for 1/2 and hour and find there copy

good luck

i launch at 4500

[ix9]

4500 !! that's quite high. is that normal for an RB20 like that, or is it just coz your boost comes on so high ?

[adam 32]

nah i dont think its normal

if u launch at 4000 it bogs down majorly

[GTS-t VSPEC]

But if your turbo isn't kicking in until after that then 4500 is fine, our cars due to the small capacity only produce power on boost, so you should launch just before it starts producing too much boost that you loose traction.

See'ya:burnout:

[adam 32]

but with my vertical power curve finding that point is a delicate art!

[macka]

I launched adams at 4500 and the tyres lit up and then bogged down after i bounced the limiter changed gears shit meself then bogged downi did a 14.5 first go,

I reckon 4300 will be the go and burnout first u will get 13.5s all day
