RDON Posted March 4, 2014 Posted March 4, 2014 hi folks. just wondered if anyone knows what the perfect revs need to be held at to get the perfect launch for a 0-62 timing or a sprint 1 on 1? Quote
brillomaster Posted March 4, 2014 Posted March 4, 2014 gonna depend a lot on the conditions... on an ice rink, probably about 800rpm, in third gear, no throttle maybe... on a dry dragstrip with sticky drag rubber, you can probably dump the whole lot at a launch and it wouldnt wheelspin. somewhere in the middle, say a dry day, smooth tarmac and fairly decent tyres, with a standard zed, maybe 4000rpm? though to be honest i can count on two fingers the number of times i've tried to do a quick launch in the zed, and both times the tcs cut in, so i clearly need more practice!

RS8055 Posted March 4, 2014 Posted March 4, 2014 As brillomaster says, depends entirely on conditions! In dry conditions on the road, I'd guess around 3000-3500rpm before you dump the clutch. Quote

If your going to try and launch the Zed at least do it properly and take the traction control off. The only driver assist you need is your brain controlling your foot on the throttle. You are spot on though otherwise ~ all depends on the conditions and road surface. 1 Quote
350zedd Posted March 5, 2014 Posted March 5, 2014 Tried this years ago in two cars I had......broke a half shaft on one at an autotest trying for a quick getaway and demolished a gearbox on the other leaving the girlfriends after an argument. Vauxhalls though not Nissans. Quote
BulletMagnet Posted March 5, 2014 Posted March 5, 2014 Just rev the tits off it (but only after having been to Abbey to have Syvecs installed and activating Launch Control before aforementioned revving of tits) 1 Quote

Ekona Posted March 5, 2014 Posted March 5, 2014 The amount of revs isn't the problem. It's how much you like having a clutch. 2 Quote
tomdotc Posted March 5, 2014 Posted March 5, 2014 (edited) 3000-4000rpm in normal dry conditions I'd say Edited March 5, 2014 by tomdotc Quote

GIXXERUK Posted March 5, 2014 Posted March 5, 2014 Before doing a launch - Always step outside of the car to make sure it's not yours 6 Quote
Keyser Posted March 5, 2014 Posted March 5, 2014 My new clutch came with instructions on "how to prepare clutch for drag starts" If I do it (with traction control off) the back of the car disappears in a cloud of smoke then the better half complains about me buying a "another" set of rear tyres Quote
WhackyWill Posted March 5, 2014 Posted March 5, 2014 Dry conditions traction off use 4000 RPM, feed the clutch don't just dump it, keep the revs up. 3 Quote
Wayne370Z Posted March 5, 2014 Posted March 5, 2014 You got some grudge match lined up with a VXR ?.... 1 Quote
RS8055 Posted March 5, 2014 Posted March 5, 2014 Certainly sounds like a grudge match to me..... Sent from my iPhone using Tapatalk Quote
RDON Posted March 5, 2014 Author Posted March 5, 2014 not a VXR lol a 310 bhp golf edition 30! bragging rights need sorting lol Quote
RDON Posted March 5, 2014 Author Posted March 5, 2014 never heard of Syvecs, I bet its not cheap? and whats involved? Quote
BulletMagnet Posted March 6, 2014 Posted March 6, 2014 never heard of Syvecs, I bet its not cheap? and whats involved? It a replacement ECU, unit cost is £1920, AFAIK available through Abbey Motorsport and Horsham Developments Quote
Ekona Posted March 6, 2014 Posted March 6, 2014 not a VXR lol a 310 bhp golf edition 30! bragging rights need sorting lol Seriously? Just go to Santa Pod then. You'll be quicker off the line, and then he'll murder you with all that torque. Ultimately you've got the slower car, but I also know which one I'd rather be driving. And it's not the FWD scrabble wagon. Quote

JetSet Posted March 6, 2014 Posted March 6, 2014 Dry conditions traction off use 4000 RPM, feed the clutch don't just dump it, keep the revs up. Yes, a skilled driver will feed out the clutch to get maximum traction with no wheel spin and importantly will "feel" when to change gear at the optimum time (revving it to its limit isn't always the way).
