Any idea how much torque the Helix organic clutches are designed to hold on a Coupe?
I seem to remember something like 330lb-ft. I was slightly over the limit, but you’re in a different postcode….
The clutch would occasionally slip if I left my foot resting on the pedal as it hit max boost, so it was clearly at the limit with the old turbo.
Have you thought about using the Blitz boost controller to limit the rate of boost gain? Going from no boost to full boost in 1500rpm will be entertaining for a while but could soon get tiresome. You have four different channels - they don’t have to use different boost rates - you could have different channels for different gain rates.
I specifically used channel 1 for when I had non-petrolhead passengers. 1.0 bar boost and a really gentle boost gain. It still made about 400bhp, but the gain was very gradual, so it was less frantic.
