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.

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 :(

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 :D

* Brakes that work :Oops:

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

      Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.

      Unpeeling the Orange

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
