so for the clutchless S/C pulley...

How would it 'shut down' if IATs were too high? is there a bypass in the S/C itself that would stop? - just curious... I'm loving the clutch based model, the clutchless with a belt-wrap kit just seems obscene

It wouldn't, I imagine. Just be sure your cooling system is in good order (I.e. split cooling with h/e, tank, KC, or any iteration of those things) and get a data logger or monitor like an interceptor and use common sense.

so if for some reason the IATs rise too high, you're just stuck with massive spark retard?

A great many OEM applications are successfully designed to function without a blower clutch. Ultimately, we must take responsibility for our IATs and AFRs, and not rely on the clutch as a fail-safe.

I hope the product makes it to market.

Very interested in this pulley and the recommended cooling upgrades, tuning parameters required (or will this come with a canned tune? I imagine most would want dyno tunes...) and any other things to take into account.

Sounds like this can be disastrous for someone who slaps one on and doesn't do there homework.

Worth repeating. Perhaps the tuning for the clutch defeat will transfer clutch duty to the bpv. But that won't stop the blower from pumping heat or am I off base?

Shardul, what will the tuning requirements be if any?

I hate watching my boost step up 12 13 14 15

I am wondering (even though bypass is still in place and functioning) if we will have a more steady boost rate.. Any ideas?



V THANKS!! V Don't let Dennis have one... lol

EC has developed a ecu remap for this product.

I will have the person who has the test unit post his reviews

Right now, my IATs = their ambient temps.

Shards, don't listen to Dane.

the heat is created when the air is compressed. so if the iat gets to hot I would imagine the bypass valve would open and pull in air from directly after the throttle and "bypass" the supercharger. Same effect as disengaging the clutch

yah, I guess that's a way of looking at it - when IATs get too high, what is the defeat during heatsoak? is it the bypass? or clutch disengagement? or both?

That's actually a very good question.
Wouldn't mind hearing an experienced tuners answer to that one. Such as, when are they programed to open or disengage.

This will be tuned for the bpv to open and bleed off boost
