Super Charger Boost Control

[speedtripledan]

It's on the dyno tomorrow, where he reckons that he will be tune it to aid this issue, the 1st tb is approx 1/4 open versus 2nd fully closed. It's probably not been helped by the fact that I've been driving on a rough map. If it survives tomorrow I will reassess where it sits, and go from there...

all great advice thanks

Yours might not have it as an issue, as your 2nd tb is the jenveys.

Wishing your car a safe and successful run on the rollers today.

Interesting problem of where to take the vacuum from for the BPV. One idea I read did propose a mechanical linkage from the accelerator so the BPV was mechanically opened when the throttle was less than a quarter open, eliminating any delay on bypass on snap closure.

now its dyno'd it has become a bit less savage on the sudden boost, not had chance to go for a cruise yet but at lower speeds its take more throttle opening to close the bypass valve.
