Hey all,

There's a 1/4 mile drag strip competition coming up over here, and I'm half thinking about putting the Westfield up. They've broken it up into classes so I'd fit into the 1600-2000 naturally aspirated class, so I reckon my 1.8 Zetec should do pretty well. There's hardly any Westfields over here in Ireland, and the event mainly looks to be a Fast and Furious style thing.

I'm in the middle of getting a set of throttle bodies onto the car so mightnt have it finished in time, but just wondering if anyone has any tips for 1/4 mile racing ? I've got a full screen, is there any advantage in ditching this for the day ? How about dropping the rear tyre pressure a little for better take off grip ?

Anyone got any 1/4 miles time for a Westfield ?

Thanks,

Tom

You'll definately be better without a front screen. Aerodynamically speaking that's one of the major factors. As you get to the top end of the speed range, removing the windscreen should give you a few extra MPH.

If you've got a number plate that hangs down below the radiator grill, removing that will probably help too.

Theres some 0-60 times here.

If you contact Graeme flukemotorsport@hotmail.com. I know he's done some 1/4 miles at Brighton, although his car is far from standard. :devil:

Practise you starts most drag races are won on the start line ;)

Fluke site is not very up to date on the 0-60 times I emailed Graham my 0-60 times 6 months ago and they are still not on the site :(  so far best 0-60 I have managed is 4.3 seconds but ave. at 4.5. Fastest qtr mile speed was 116mph and 12.8 seconds see my web site for videos  :D

Tyre pressure might not be worth worrying about if they're just normal road tyres.  The sidewalls won't move enough to make much of a difference to traction.

As Matt said, there's a lot of time to be found in the start so practice your launch technique and try to find the optimum combination of rpm and clutch slip to keep the engine on song.

Gearchanges are also important - quick and precise and don't hit the rev-limiter or hang on to a gear for too long if you don't have one.  Find out where your engine produces peak torque and power and experiment with changing gear to make the most of this.

Quickest my car has run has been a 13.8 at, I think, 101mph.  But I was getting terrible wheelspin in second (poor track surface and concrete road tyres) and I was hitting the rev-limiter about 50feet from the finish line - it was debatable if a gear change would have been slower than hitting the limiter for a second or so.  Oh yes, and the driver needed practice in hitting the gear changes just right....  :blush:

Thanks guys, I'll definitely try testing the launches.

Hopefully the tyres will be A032r's or maye a048r's, but that's a whole different story ...  :D  :D

I've been checking out what the competition are like, there's a tuned Mk1 GTI 1.8 16v, with a boot load of Nitrous, who usually does the 1/4 somewhere in the 12's. :0   :t-up:  :t-up:  :love:
