Nic Posted August 10, 2006 Share Posted August 10, 2006 Cam pulleys? I would definitely recommend the JUN pulleys, I've supplied a few sets of these now and they look very good quality. If you would like prices/details let me know. http://img148.imageshack.us/img148/6234/cimg0001kw0.jpg Quote Link to comment Share on other sites More sharing options...
Wez Posted August 10, 2006 Share Posted August 10, 2006 There are also accessory pulleys here :- http://www.horsepowerfreaks.com/price/Toyota/Supra_93-98/Greddy/Engine/Pulleys I would not change the crank pulley for a light weight unit, you should use something like the Boost Logic.

Lucifer Posted August 10, 2006 Share Posted August 10, 2006 Hello Sir, Notice you are in Avon. Were are based in thornbury. Why not pop up and say hi sometime soon. Under-drive pulleys are not really for the Supra. However saying that there are a few Bhp's to be had, but when you are talking about 100's that you gain for each major upgrade, its not usually done. Also you would NOT want to put an undersized pulley on the crank as its harmonically balanced. We do a lightened one, but they are not cheap.

Alex Posted August 10, 2006 Share Posted August 10, 2006 Greddy do lightweight but not under driven pulley's. Quote Link to comment Share on other sites More sharing options...
Guest jaztt01 Posted August 10, 2006 Share Posted August 10, 2006 Hi- Cheers! yeah i like the look of those cam pulleys but i was after a set of crankshaft pulleys, found these on ebay.. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=012&item=220015198122&rd=1&sspagename=STRK%3AMESE%3AIT&rd=1 Is that a good price and has any 1 brought from http://www.cdfracing.co.uk b4?

Guest dee_rz Posted August 10, 2006 Share Posted August 10, 2006 You can also get an uprated harmonically balanced lightweight crank pulley but they do cost a fair bit, titanmotorsport used on there car so i'm sure very high quality too if you want to spend alot of dough for a crank pulley, i'll be doing this next year plus cams, cam gears etc Quote Link to comment Share on other sites More sharing options...

Digsy Posted August 10, 2006 Share Posted August 10, 2006 Even the "uprated" crank pulleys with the damper don't have the bending damper that the Supra stocker has - only the torsional element. Don't underdrive the water pump. It takes feck all power anyway and you dont want your engine any hotter. Underdrive the PAS pump? Possiby, but its only on full load when you are on full lock - unlikey on a drag strip or motorway, or even a traffic light Grand Prix. Undredrive the ACU pulley? Difficult as the pulley has a clutch built in. Easier to just switch it off, which the ECU does anyway at WOT. Underdrive the alternator? Possibly, but by now it hardly seems worth the bother :-) Plus its one of the hardest pulleys to change. Quote Link to comment Share on other sites More sharing options...
