Hi Guys, We have just launched ( or in the case of two, soon to launch) a complete range of MCS pullys and one other interesting associated product. For now here is a list,though
I will put up some pics and more info as we go along.

1) GTT Supercharger Pullys (16%,17% 18% &19% )
2)GTT Idler Pulley (stock size or +6mm size)
3)GTT Comp Idler Pulley (deeper housing +two separate ball races ) -Available mid Feb
4)GTT Tensioner Pulley - Available mid Feb
5)GTT Crank Pulley (2 piece ,6 spoke,hard anodised L168 alloy, s/steel location boss, available as stock diameter or + 4.5mm)
6) GTT Tensioner Limit Stop. ( prevents overtravel when belt snaps which sends the tensioner damper eye straight into the crank pulley/harmonic damper wrecking it in the process)
Regards Roland GT Tuning..... the new forum friendly sponsor
ps Mini 2 gets everything GTT first!

Will item 6 be available for when I come down in early Feb Roland?

Cheers,

Henry

Hi Henry,
It should be. If you want it fitted,fitting will be free as were working on your pullys anyway
The parts themselves come to one million pounds exactly ,ok £24+vat then.
Best Regards Roland

A million

A bargain if ever I saw one I'll want one of these as well but without the GTT adornments if possible please. I don't want my pulleys to stick out toooo much if you know what I mean This should protect my spangly new Crank Pulley if, heaven forbid, my belt snapped

Cheers,

Henry

No problem Henry, we'll paint it black then kick it round the car park a bit to give it a
'BMW used look'. A bit like buying stone wash jeans with holes already in the knees I suppose. Regards Roland

Here are some pics of the new GTT tensioner overtravel limit stop & the GTT Lightweight Alloy 2 piece Crank Pulley. Will add some text later.
Regards Roland.

[Andy@Ross-Tech.com]

I like the tensioner stop, pretty clever!

[roland2003]

cheers Andy.

Ok here is some blurb off the cuff on a couple of the products:-
GTT TENSIONER STOP This simple product ensures that in the event your drive belt
should snap (which is bad enough on its own), the tensioner assembly travel is limited
preventing it slamming into the crank pulley,or harmonic damper/balancer as the OE
part is called.If this happens the eye of the mini shock absorber on the tensioner assembly
hits and then grinds away the pully. If this happens you will need a new crank pully for
sure ,not cheap! The OE tensioner has a puny excuse for a stop that simply breaks off
under the force of the belt snapping,or as was the case with our car just missing a gear!
Fittment is very straight forward ,and makes sense to fit at the same time as any
work in the pully area. In fact if we're doing the pullys we dont charge anything for the labour The parts cost £24+vat.

GTT COMPETITION CRANK PULLY'S These are manufactured in L168 aerospace
aluminium,to a strong 6 spoke design,and include some special features:
The centre boss is made in steel ,this is because aluminium should not be used as an
interference fit over steel (ie the crank nose). The main reasons being different rates of expansion,and risk of 'picking up' where the alloy effectively welds itself to the steel
during removal. With our system the boss is heated ,and fitted to the crank nose. The alloy pully wheel is a sliding fit over the boss and is secured using 6 bolts.
The pully is also hard anodised,although only 50 microns thick is actually harder than steel
coupled to this its anti corrosion properties are excellent. This should not be confused with
clear or colour anodising which does not share these properties.
What does the pully achieve? It achieves reduced rotational mass (stock=7LB,GTT=1LB)
resulting in faster engine spin up and improved performance.
As a bonus we also offer this item in both stock diameter & +4.5mm. The latter
is approx the equivalent of 'minus another 3%' on your Supercharger pulley therefore
is particularly useful to people with either -15% pulleys or JCW (-14%) pullys who would like a little more boost at the same time. The large version crank pully will also spin the
aircon & alternator pullys a little faster, we do not see that as a problem.
Initially this item is sold as a competition item , and fitted only. We are fully aware of the
damper v no damper discusions which TBF have merit. After min 20,000miles we plan to
strip and inspect the crank journals, at which point we hope to offer this product for road
use. TBH I am confident of no long term wear issues, as we have attemped to murder
the crank on other 'no damper' engines and not suceeded Price £129+vat
Phew! Regards Roland Gt Tuning

How is the 2 piece Crank Pulley 'collar' installed and removed from the shaft? Heat?
Please either post or PM me prices.

Also, how are your blower pullies installed? Press fit or like the Alta and others?

THANKS

[roland2003]

You heat the centre first ,it then slides on. To remove you use a GTT puller ring . I dont
recommend applying a torch to it while on the car,I think you could damage the cranks rubber seal or oil pump. To remove the pulley itself you can just undo the 6 bolts and it slides off. If you used loctite during fitting (to spread the load across the full depth of the wheel),you just screw in an M16 Fine bolt to the thread in the wheel,and it winds off. Our SC pullys are all steel 'heat to fit' interference fit ( like OE). Again to remove without damage we use a special GTT puller ring, these are not intended for DIY fit though if you want one DIY we could supply. Cost ? Ill let you know.
Regards Roland GT Tuning

[stu(pid)]

Roland - some very exciting products!!
How does the tensioner stop install? Would I have to remove the tensioner?
How much do you charge for the Bypass Valve operation optimisation? Is it worth having this done if you have no yo-yo effect after a BBR220 conversion?
Sorry about all the questions - I'm so excited (sad, I know!!)


Thanks

[roland2003]

Hi Stu, the GTT bypass mod is aimed more at increasing power than 'anti- yoyo' so
is worth doing.
The GTT tensioner limit stop does not require removal of tensioner to fit. Also no special tools required. Best Regards Roland GT Tuning

[CooperSdriver]

How can I order here from the U.S? I am interested in alot of your products. The competition crank pulley, and a couple of other products..


Thanks again

Hi Roland, with the tensioner overtravel limit stop, is it just the piece with GT TUNING sticker which is put in place of the original piece or is there further mods to the spring as well? Is there still enough travel left to take the normal belt thrashing without it bottoming out?

Thanks John.

[XTREEM]

How is there resistance? is there a nylon washer on the bolt through the elangated hole ? That has resistence but still lets it slide?

[roland2003]

Top secret! The travel allows it to go back to the same position as stock allows ,and forward to the point where the little twisted 'T' is (before it breaks off that is!)
