Guest Pricer69 Posted July 15, 2014 Share Posted July 15, 2014 hey guys just wondering is anyone could help me out. ever since ive had the car the acceleration has been abit sluggish, going down the motorway going 60 in 5th, put throttle down and it would take at least 10 seconds just to get to 70:( i got a mk4 supra sz NA.. my mate has exactly the same car with same mods and his pulls much quicker than mine does, it just seems i only have decent acceleration in 1st and 2nd :/ my clutch pedal is really high and someone i know said it is the clutch on its way out but it isnt slipping, could it be that? i literally have no idea what it could be so im hoping one of you lot could help me out cheers Quote Link to comment Share on other sites More sharing options...
Graham1984 Posted July 15, 2014 Share Posted July 15, 2014 Clutch might be slipping, test it in higher gears and flooring it at 30mph. On another note when doing 60mph put it in 3rd instead. Quote Link to comment Share on other sites More sharing options...
trebor69 Posted July 15, 2014 Share Posted July 15, 2014 Can usually tell by watching your revs climbing much quicker and out of sync with the speedo. Quote Link to comment Share on other sites More sharing options...
Guest Pricer69 Posted July 15, 2014 Share Posted July 15, 2014 the revs dont go up quicker than the speedo. i floor it and the speedo picks up slowly.. like real slow i was goin 60 in 3rd the other day floored ot and there was a 2-3 second delay before the revs picked up.. but they were picking up slowly lol i dont inderstand Quote Link to comment Share on other sites More sharing options...

trebor69 Posted July 15, 2014 Share Posted July 15, 2014 Make sure everything induction wise is tight and you are not sucking any air in where you shouldn't be. Quote Link to comment Share on other sites More sharing options...
Kendo11 Posted July 15, 2014 Share Posted July 15, 2014 Make sure everything induction wise is tight and you are not sucking any air in where you shouldn't be. As above. Could be something daft like a vac hose? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted July 16, 2014 Share Posted July 16, 2014 Funny I was going to ask pretty much the same question only mine is an N/A. At 90 leptons plus it really drags it's heels and once I found a private place to test the limiter it was a ridiculous job trying to get it above that. Mine seems to pull OK low down but like the OP when it starts to get above 60 the power appears to peter off. I am in two minds on wether to spend money on new leads, distributor etc or just leave them until the winter and get a TT transplant. Problem is I might end up leaving it another year though so if there is anything cheap and easy to look at would help. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted July 16, 2014 Share Posted July 16, 2014 Have you driven any other N/A's as a comparison? My first thought would be are the calipers or caliper sliders seized, and the brakes dragging? Feel the discs after a few miles on the motorway without touching the brakes and coasting to a stop.

That had crossed my mind as the power seems to be speed related not engine rev related I'm either chronically un-aerodynamic or something is sapping the power. I get a vibration from the back that manifests itself in and around the 90-95 area as well so I suspect a back caliper isn't playing ball. I am just putting together a new UK spec front end may end up having to go with the back end as well. Quote Link to comment Share on other sites More sharing options...
