Supercharger Spring Advice
Supercharger Spring Advice
Some will remember me from LOC and briefly on OJC. I've been off the scene for a while for variouys reasons but now need some advice.
The bypass valve spring on my s/c decided to destroy itself last night and i'm now unable to drive the car without a suitable replacement. The one i had fitted was (i beleive) the original one that looks like a slinky spring inside a biro. I know they did cange to a v-shaped one, and indeed i acquired one a few years ago from TTE, but sent it on to a fellow LOC member (Mr Mole i think) when he was at a loss and needed a spring.
I contacted gord yesterday evening and he advised me contacting bemani (which i've done) and they have said they 'might' have one or two of the original biro slinky spring type ones somewhere, but he couldn't say for sure.
If anyone has one spare or knows where i can get one (either type) then please let me know.
Cheers

you could disconnect the throttle cable to the valve and run with it permenantly open.

I can't drive it because it sounds terrible over 2k'ish revs.
So if I disconnect the cable, what does driving with it open do? I thought the spring shuts the valve? How exactly does the spring/bypass work in regards to the s/c?

28-08-2020, 10:03 AM #9Ahhh right I see. So I'd be running the car as N/A then and no boost? Why does it sound so loud when the spring is missing then - thought it had something to do with releasing pressure :-S
And yes you'd just be running it like an n/a with a charger noise lol

28-08-2020, 11:02 AM #10Because the throttle wire pulls the bypass closed, but the spring doesn't pull it back so the air has nowhere to go when you close the throttle so it stalls the charger
