RobSheffield Posted February 26, 2007 Share Posted February 26, 2007 Excuse the line line (linelock) and nrakes (brakes) typo's! Did you know you can edit things?! All a linelock does is prevent fluid moving back out of the calipers to the master cylinder meaning the brakes remain on. Line lock the fronts and the rear wheels wont have any brake force applied, meaning the autobox fluid wont boil quite as quick Quote Link to comment Share on other sites More sharing options...
DannyW Posted February 26, 2007 Share Posted February 26, 2007 No point in doing a burnout with road tyres, you will actually lose grip if anything. Just a little spin to clean crap of the tread is more than enough. Only worth heating them up if you have proper drag slicks. Quote Link to comment Share on other sites More sharing options...
NUTKIN Posted February 26, 2007 Share Posted February 26, 2007 I was thinking the same cause with my road tyres if i do a burn out there useless for grip straight after. Its as if u have put oil over them they slide everywhere an iv got p zero rosso on mine so it aint the tyres. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 26, 2007 Share Posted February 26, 2007 I gotta say that my Eagle F1's definatly got grip with heat. I knew for sure it was going to be a bad launch if i didn't get enough heat in the tyres. Quote Link to comment Share on other sites More sharing options...

Well he definatly will have more knowledge than me at dragging but i know for sure the way MY tyres reacted to a UK prepared drag strip which is different from a US one.

RedM Posted February 26, 2007 Share Posted February 26, 2007 Try it when stopped in a puddle. Especially if there is a BMW behind you that has been driving too close for the conditions. Quote Link to comment Share on other sites More sharing options...
Branners Posted February 26, 2007 Share Posted February 26, 2007 there was a discussion many moons ago that power braking a car can cause cavitation in the fluid (it goes all bubbly) which isnt a good thing. Anything up to 20 seconds was okay, but long term power braking wont do the gearbox a lot of good in the long run. On a cold day its got to help to get some heat in to the tyres, but to get heat in to road tyres takes a lot of time and white smoke which also isnt good.

lambertpig Posted February 26, 2007 Share Posted February 26, 2007 i found that prolonged burnouts on street goodyear eagle f1s gave me less traction??? i now just do a quick burst. did some good lookers though. Quote Link to comment Share on other sites More sharing options...
tDR Posted February 26, 2007 Share Posted February 26, 2007 Im sure Brian AKA tDR has got the lock up switch on his Auto, try Pm'n him and see where he got his from?? G. Kinda right George.... the lock up switch is the one that allows me to lock the torque convertor (part of an autobox) so that it won't slip, which I mainly use for motorway driving. I also have a Titan / Hurst line lock kit fitted for the purpose of this season's drag racing, mainly so that I no longer need to overcome the rear brakes for burnouts and launches. I have the switch positioned so that I can operate it with the heel of my left hand whilst on the gear lever - works very effectively but have yet to use it in anger on the strip. Also, I hold the record for best 60ft time on normal road tyres for this site so I think this would back up my opinion that getting some heat into road tyres via a burnout does help... I tend to give normal road tyres a good 15 - 20 sec warmup about 10ft before the start line then approach the line with a rolling burnout. Cheers, Brian.

5upra Posted February 27, 2007 Share Posted February 27, 2007 But I can't get it spinning in the first place - assume you have a manual where you can suddenly drop the clutch - which I can't do in an auto. Recall seeing some guy on TopGear a while back in a TVR being able to spin it 360 then carry on in a straight line. He had a had operated brake button for the front brakes to acheive it. I have a n/a auto and it can be done even with wide tyres. Put your left foot on the brake pedal. If you have traction control, turn it off, if you dont then obviously you cant! Then right foot on the throttle keeping the car in 1st ( low ) gear. the wheels will spin. if they dont at first just floor it and they will go. Have fun !!

Robbie Posted March 16, 2007 Share Posted March 16, 2007 I hold the record for best 60ft time on normal road tyres for this site Brian. I use my MTs on the road as much as possible ! These are my nomal tyres. Whats your 60 ft time? Quote Link to comment Share on other sites More sharing options...
b.weeks Posted March 16, 2007 Author Share Posted March 16, 2007 Just to clarify - the line lock kit holds the front brakes, but lets the rear brakes free? Meaning less wear on rear pads, and less strain on the transmission? tRD - useful post, cheers. Quote Link to comment Share on other sites More sharing options...
tDR Posted March 16, 2007 Share Posted March 16, 2007 I use my MTs on the road as much as possible ! These are my nomal tyres. Whats your 60 ft time? 1.7 sec at Elvington... we'll soon see what I get at the Pod in April. That's on BFG DR's. I know you've had some good times on those MT drag tyres of yours at the pod on a prep'd surface (1.5sec was it?) but they're hardly normal road tyres! I managed a 2.01 60ft at Crail (another airfield surface, pretty crappy) on Falken FK-452 normal road tyres which I can use in the wet I'll give you a wee 60ft race at the pod in April - always good to see Supra's being launched properly! I love surprising 4WD's off the line Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted March 16, 2007 Share Posted March 16, 2007 Yep, good results with line lock kits apparently. I tried to do a mini-burnout in my auto the other day and failed miserably! you just need a heavier right foot Quote Link to comment Share on other sites More sharing options...
