Hi Kyle, Just to go back on topic what are the advantages/disadvantages of ATI or BL versus Stock Toyota? Cheers Matt. Quote Link to comment Share on other sites More sharing options...
kylestt Posted March 11, 2008 Share Posted March 11, 2008 Hey Matt, This is taking right off their site, it kind of hits home with this thread about falling apart ;-) "Dampened Crank Pulley is a great option for those looking to replace the stock piece. The stock pulley seperates at the rubber and can cause great damage to surrounding accessories and the body of the vehicle when it comes apart. This failure is common with high horsepower and high mileage Supra's. The Titan pulley is SFI approved and legal to go 10.99 and quicker. The pulley is great for street and racing use. We use these on all the street and race Supra's that are built and this is the choice of many champions usign the 2jz in the last 3 years. A must have for anybody who wants to save $ from a costly seperation of the stock pulley." Quote Link to comment Share on other sites More sharing options...
Guest torque monster Posted March 11, 2008 Share Posted March 11, 2008 :eyebrows:Just be aware 1 time out of 10 these suckers argue and they don't always want to leave their 15 year+ old home on the crankshaft .. may end having to take out the rad etc and use a specialist puller for the odd one. £300-350 for a Toyota pulley fitted. I'll stop tickling then... Quote Link to comment Share on other sites More sharing options...
SimonB Posted March 12, 2008 Share Posted March 12, 2008 Just a comment about that sales blurb, the stock ones do fall apart with age, and especially if they have been heated by people trying to remove them, but "high horsepower" has absolutely bugger all to do with it. It's a pulley, it makes no difference how much power the engine it's attached to has. The only thing that's going to affect it is the RPM it's spinning at.

kylestt Posted March 12, 2008 Share Posted March 12, 2008 the high horsepower comment I believe, and dont quote me to this is in regards to havning a built internal motor. Tons of machine shops recommend the aftermarket dampeners when having a built motor. Why so, i honestly do not know but every big machine shop in the USA recommends them.

matt k Posted March 12, 2008 Author Share Posted March 12, 2008 I would have thought that increased torque would have some effect, and delivery, Like the way a big single would double the torque being applied in a small rev range. Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 12, 2008 Share Posted March 12, 2008 Can I just clarify that the rules on traders in tech is thus: If a member has a techie question like this and specifically asks for people to quote them on replacements and or alternatives, then traders quoting prices is allowed. If another member in the course of discussion asks for prices and a quotation, then traders quoting prices is allowed. If a punter has a techie question like this and a trader wades in with an offer of parts/prices etc out the blue then that's a quiet word and possibly an edited post. Traders fishing to get an ask on prices is borderline and will be dealt with on a case by case basis - which is what happened in this case to my eyes Personal sales counts as being a trader for the purposes above. Oh and anything quoted as techie gospel by traders on products they sell, you may want to engage scepticism factor 10 first See if it is backed up by people who don't make money out of them. -Ian Quote Link to comment Share on other sites More sharing options...
paul mac Posted March 13, 2008 Share Posted March 13, 2008 i am re-building a motor at present so have been doing a lot of reading of generic tuning books, without exception every one has said on a road car stick with the stock pulley damper a hell of lot of R & D goes into these pulleys, does any one seriously think the aftermarket ones get the same level of testing, i'm sticking with Mr T Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 13, 2008 Share Posted March 13, 2008 There is, and I'm sure this has been said before but here goes, a world of difference between the term "balanced" and "Harmonically tuned". A balanced pulley means it doesn't oscillate or wobble around when it spins - much like the process of balancing your wheels and tyres. That's all it means. A harmonically tuned torsional vibration damper (TVD) is, of course, 'balanced', but it is also attuned to cancel out the nodding and flexing characteristics of the 2JZ crankshaft. The stock one is a TVD and you can read all about it here Required reading on the subject I think and despite me posting it I must point out it was written by Digsy, our man in the powertrain industry who designs this stuff for OEMs. Given that pedigree vs any amount of marketing blurb, I'll stick to OEM. -Ian Quote Link to comment Share on other sites More sharing options...
