Mick, to be fair I did give the car a good wash, too.

That BM has a stock 5 speed manual BMW transmission driving through an OEM BMW driveline and diff. Basically it's all factory apart from a beefier clutch.

Adrian, stock bodywork will be replaced, it's just off to fit up the parachute anchor. Using a Stack dash with a Stack boost gauge, Autometer shift light and warning light. Erik will work out how to fit all that shit into the OEM dashboard. Staying with the BMW ECU with piggyback. Running a larger Garrett ball bearing turbo now.

I love it when you talk like that Adrian. ;-) Cool, here are some direct links to the movies. You need DivX to watch them I think. 25th August 2004 First ten second pass incar, stand File size 15.8M Codec: DivX Pro 5.2 First ten second pass stand File size 9.8M Codec: DivX 5.1.1 18th August 2004 Five passes on street radials File size 65.7M Codec: DivX Pro 5.2 In car showing boost gauge, speedo and tacho File size 9.8M Codec: DivX 5.1.1 28th July 2004 Three easy pieces File size 24.8M Codec: DivX 5.1.1 Alternate takes of wins vs Raima and Mopar Boy File size 15.5M Codec: DivX 5.1.1 Racing Raima File size 17.7M Codec: DivX 5.1.1 Racing Mopar Boy File size 24.8M Codec: DivX 5.1.1 21st July 2004 21st July passes File size 30.6M Codec: DivX 5.1.1 14th July 2004 14th July passes File size 32.0M Codec: DivX 5.1.1 Obviously the Winter months are when the badass contingent comes out to play. Sounds like you've been bitten by the bug! Hehe. The new turbo is mocked in place inthe foreground, the old turbo (the one I used on the ten second pass) is held by Herbert in the background. M Coupes only need one turbo to run you know!

No problem, drag racing is fun! Your 2.3x 60' is shithouse, but you knew that. That's good in that it won't be hard for you to do better. And every 0.1 improvement in your short time is worth 0.15 - 0.25 in your ET. On that basis if you can nail a 2.0x 60' time (very doable with your car) you could shave up to seven tenths off your ET. That would put your ET at 14.0X. From there you will crack a 13 second pass with more experience. Hey thanks for the kind words. We really enjoyed that night, it was the result of 42 passes over 7 weeks to crack a ten. Click on the link in my signature to see a movie of that pass. We are currently halfway through the next phase of development and should be back out at WSID in the April-May 2005 timeframe. See you there when the air is cold and dry!

It's a good idea for people to decalre that they are somehow affiliated to a workshop though. That way you can take this fact into account when evaluating their opinion.

Regarding tyre pressures I'll post up my experience. With street radials 285/35 R18 I've tried all pressures 16psi to 40 psi and found that the OEM pressure works best (ie 36 psi for my tyres). Lowering the tyre pressure in a 30/35/40 profile tyre is a waste of time IME. Once you've got some drag radials with 50/60/65 profile you can benefit immensely from fidning the right tyre pressure. For my 275/50 R15 drag radials we found between 12-14 psi works best. Again, try all the combos and record each time, then analyse and find what works best. With all the above, don't forget that each race night has different weather conditions which means there is no one perfect setup; it changes night to night and even changes on the same night.

The weather conditions wouldn't help trap or ET. Maybe allow 2-3 MPH compared to a cold Winter night. Regarding your tyres, street radials are shit for drag racing. With 17" or 18" wheels and tyres you've got bugger all sidewall as you said. They are never going to cut it for a good short time. I would say that a 1.7x 60' time on street radials would put you in the elite racer category. With the power your car has I would say you'd be cheering if you got a 1.9X 60' time. Best bet is to model the successful racers with similar setups to you. You want to get BF Goodrich Comp TA drag radials with a 50, 60 or 65 profile under your guards. If you want to go all out, then get slicks. Regarding squat, you don't want it! With IRS rear suspension squat on launch will alter the camber radically and unload around 50% of your rear tyre contact patch. You don't want squat. What you want is zero negative camber on hard launch, keeping all that precious rubber contacting the ground. I've always mantained that burnouts on street radials are a wank. The best short time I've ever done with street radials came after the ANDRA official at WSID abused me resulting in me getting the shits and doing a huge burnout. So bugger me, maybe I'm wrong! Try it both ways and reccord which one gives you better short times. With the burnout you only want to turn the rears over until they smoke. No static rim scratchers. Good luck and remember that every time you race you get better! You've already graduated to the few who actually do it rather than just type about it on the internet.

Smart move. Then you can drag race in Sydney at ... er ..

Ooh, I so want a piece of you this time! ;-)

I gather this is the dogshit DYO setup? Heads up racing only for PRO RWD takes all the fun out of it.

Adrian, are you planning on racing at WSID?

Sean, what you have is BFG Comp TA DRs, and I reckon they are the dog's bollocks for street legal tyres. I ran 12-15 psi on mine, but it all depends on your driving style and vehicle. Start at 18 psi and work your way down by .5 psi until your short times stabilise. You want to launch at the highest RPM you can with near full traction.

Slicks only come in 15"

Yeah, with street radials.

Gives me a 2.32 second 0-60 mph time ..

Well done John! Nice short times, too.

Argh .. M Coupe won't be ready.

Turn to page 85 and bear witness.

Yeeeeeeeeeeehaaaaaaa! Awesome pass.

It never ceases to amaze me how jealous some internet "racers" are. If only keyboard tapping could make a car go faster.

Awesome Mark .. tens are beckoning with some more passes ...

Bu5ter: Thanks dude! R33vit: No problem! nv033: IT wasn't a magical run, it was a shitty run. They only let me have one pass so I couldn't dial in the tyre pressure, launch RPMs or anything else. The car stepped out hard in second and unloaded the slicks in third. Oh yes, there's plenty more left in her. However the car is now being dismantled ready for the rollcage and some engineering, including an engine upgrade to produce more power. Adrian: Good on you mate and thanks for the encouragement!

Hehe. Yep, had the Mickey Thompsons on for the first time!

Adrian, I'll let the timeslip say it for me ;-) R/T: .168 60': 1.600 330': 4.709 660': 7.092 @ 104.92 1,000': 9.086 ET: 10.775 @ 134.35 Car booked for rollcage installation! Adrian, can you update my timeslip info mate? I'll send you the pic of the 'slip.
