Drag racing tips...
Discussion
I seem to have signed myself up for a charity drag racing event (Race the runway at Edinburgh airport).
I've never done a drag race before (other than the odd TLGP!), and I know there's going to be a lot of expensive metal there.
Anyone got any tips to try and maximise my chances of letting the Cerb make a decent show of itself?
Would getting a set of part-worn 888s or Mickey Thompsons (if they even make them in the right size) make that much difference?
Oh, and apparently its a 1.8km track rather than the usual 1/4 mile.

Drop your rear tyre pressure somewhat. I found 14psi was good for me on T1Rs but opinions vary.
R888s will make a difference, I suspect specialist drag tyres much more so.
Controversially it is said that adding weight in the boot will improve your grip at launch more than it slows you down, but that may only be true for a shorter 1/4 mile run.
ETA - Don't stall it on the line - twice... DAMHIKIJKOK!

Yes on the R888s. They made a big difference to my Chim over the T1Rs.
I now use Mickey Thompson street ETs and havent found much improvement over the R888s but i blame my suspension.
I wouldnt normally recommend adding weight in the boot, but if the start line is really poor for traction then it could pay off, especially in the longer wheelbase cerb. You should also have the grunt to overcome the extra weight.
Warm up the R888s with a mild burnout just enough to start smoking is enough.
Try to find the sweet spot on launch.... not too much revs and feather the clutch a little.
If you get the start right in a Cerb then not much will be able to catch up....
enjoy!

Im also doing some drag racing on 1/4 mile runs. Never done it before was wondering if it was worth putting some slicks on or not.
Slicks may be a step too far... if they 'hook up' like they should then you may be snapping a driveshaft... or worse!R888s are a big improvement over standard road tyres.
I reckon mosst Cerbs would better their 60 foot times by 2 or 3 tenths and would cut 1/2 a second or more off the 1/4 et. Money well spent.

The drag racing forums in the US reckon that 1 tenth in the 60ft, is worth 3tenths over the line.
i have probably done triple figures runs wise with mine now, and you know pretty much as soon as you let the clutch out if its a goodun or not!

Sub 2 seconds are required for a decent time.
I manage mid 1.8s on the Mickey Thompsons but know i can get another tenth off with the right suspension setup.... so maybe low 11's to come.
With a boost from my engine rebuild and the nitrous upgrades may be running times similar to Brummmie.... i wish
1500-1800rpm if memory serves me correctly.
As said drop the rears to about 15-17psi and pump the fronts up to 45-50psi. If you have adjustable suspension then get the rear nice and bouncy and the fronts set firmly.
Brummie has summed up the clutch, you'll know straight away if you've had a good or bad launch, you need to feed the clutch, bite, hold, release, you'll see what I mean once you've had a few runs, then just full throttle changes to the line.
Let us know how you get on.
