I’m after a pulley from the GT4/270 upgrade to go with a 270 ECU that I’ve acquired. Just wondering if anyone who has used the upgrade has the pulley they’d be willing to sell if they’ve moved onto a different set up. Lotus will sell me one but for a one-off the cost is outrageous. Ta 
Thought the 270 pulley was just a 3.1??
I have 3.1 , 3.0 , 2.9 , 2.8 all in stock…
I have a 74 mm here .
£50 if you want it
On the lotus cup regs the 2-eleven pulley (where I have been told that this is the GT4 pulley) is shown to be 76.5mm diameter which is near as damn it 3".
Lotus have given me a slightly different measurement which is in between 3" & 3.1".
To be absolutely sure I’m using a suitable pulley I was after the genuine lotus part ideally a second hand one that was no longer in use…a long shot I know.
Dave, I’m currently using one of your 3" pulleys which is fine but I haven’t been on track with it yet. I just want to be safe than sorry
Get it on a dyno to make sure the AFR is ok, then just enjoy 
Not a bad shout Ade, cheers
Rowland at Lotus has confirmed the 270/GT4 pulley to be 78.53 mm which is near as damn it 3.1"
Dave, looks like I’ll be investing in one if your 3.1" pulleys
