Robbie Posted May 30, 2007 Share Posted May 30, 2007 can someone tell me the part no for a UK spec auto cam belt? I want to put an aftermarket one on . Link to comment Share on other sites More sharing options...
Digsy Posted May 30, 2007 Share Posted May 30, 2007 But why? Link to comment Share on other sites More sharing options...
michael Posted May 30, 2007 Share Posted May 30, 2007 They come in pretty colours and are as strong as a bullet-proof vest, if someone shoots my car the last thing I want is a broken cambelt. (I'm getting a blue one BTW) Not sure why you need a part number for a standard one if you are buying aftermarket though, they are the same size for all aren't they?

Robbie Posted May 30, 2007 Author Share Posted May 30, 2007 As for why. Ive revved my car passed 9500 rpms many a time now and I just want to prevent any possible stretch on the belt! I'm also getting the BL billet tensioner so I thought if I'm getting a new one then get the best you can! they are the same size for all aren't they? I wasnt sure if there was a difference between auto ,manual uk, jap. so I thought I'd ask:rolleyes: Link to comment Share on other sites More sharing options...

What kinda build do you have? just read your sig...then viewed your garage...that must be a beast! (Is it safe to rev past 9500rpm though?)

Yeah so far. 10000 miles and still going. My car is off the road for a round of bits including cam belt tensioner from bl hence the cam belt. Im also getting a better gasket for the inlet plenum to stop some heat transfer and injectors for a direct injection methanol/water mix for 2 bar boost. Ive pushed the rev counter round 270degrees now a few times at pod by mistake.... Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 30, 2007 Share Posted May 30, 2007 If you have managed to rev the thing past 9500 the last thing you should be worrying about is the cambelt. More like rod bolts, rods and the crank... Link to comment Share on other sites More sharing options...
JustGav Posted May 30, 2007 Share Posted May 30, 2007 Why are you able to go that high? Surely your engine management should have some sort of limiter to prevent that... Link to comment Share on other sites More sharing options...

Average cam drive torques decrease with speed, anyway. Although the peaks do increase, they become much shorter in duration. TBH I'm not sure if belts are specced for the peaks or the average.

bolarbag Posted May 31, 2007 Share Posted May 31, 2007 And you ran on a standard belt all that time...crikey! So whats the price on a bottom end alone like that? Is the crank not uprated? Link to comment Share on other sites More sharing options...
Robbie Posted May 31, 2007 Author Share Posted May 31, 2007 The crank, flex plate, rods, piston etc were all balanced together. The OEM cranks are strong enough for the power I make! Link to comment Share on other sites More sharing options...
bolarbag Posted May 31, 2007 Share Posted May 31, 2007 And what power would that be if you dont mind me asking? Link to comment Share on other sites More sharing options...

bolarbag Posted May 31, 2007 Share Posted May 31, 2007 And your almost making 9's! WTF! I know its an auto but didnt think that was possible with that power on a Supra, so you reckon your low times are due to high reving and auto box? What sort of torque?
