toothed pulley/belt on an eaton??

[LregG]

Took rob out for a spin tuesday night and i'd seemed to have lost power compared to when my car was mapped and boost dropped off big time at 6200rpm compared to the 7100 rpm at the time of the remap. When i got home i felt the 15% smaller pulley to find it was red hot and the belt had definately lost some tension

You can see the rubber in the grooves!!!



This was really getting my back up so i thought about toothed pullies, luck would have it that i had already had a PSD keywayed shaft fitted to my eaton and a quick call to PSD and a drive down there gained me a 58mm toothed pulley for a G40 charger, a sleeve was needed to fit the pulley to the eaton shaft but with an engineering company 2 mins from my work this wasn't a problem

I had to remove and borrow robs toothed belt crank and alternator pullies (cheers rob), fit them up and work out how far the eaton toothed pulley would need to sit and have the sleeve and pulley machined to suit and an extra larger key made for the keyway. Anyway the end result>

Toothed eaton pulley



The pullies line up lovely



Hopefully the belt will be okay as the charger is sitting a little pissed (arse end sitting slightly further towards the front of the car than it should making the belt want to ride off of the pulley as it turns ). I've got it to sit as best as i can but its still not 100% in line, the pullies are definatley lined up

I've not given my car a proper blast yet and probably wont do until after the rolling road tomorrow (he says knowing that the temptation to race the lotus on the way may be to much). I'm just happy in the knoweledge that i will not get anymore belt slip
