Lightbulb Main hose came off VF S/C on Highway

Hey folks -

I write this via Blackberry from Mom's summer place in the MA mountains - normally a great boosted drive on big interstates and winding country backroads. BUT TODAY (heat index 110) my 2 month old VF Supercharger popped its primary air hose clear off the Vortech S/C unit while on the highway at 75mph. This triggered a whole lot of jerking back and forth and ultimately a stall. We managed to get off the road and re start while rolling and make it to a random service station. Nice guy there BTW. We had to find a new clamp and wait a good 45 mins for the thing to cool enuf to work on it. We got it on and I pulled (sad to say, with boost) away from the station with frustration and right off came the hose again.

I called my race shop (who had popped off the hose to put on a high performance bypass valve last week) and they had me use brake drying spray and scuff the edge of the chrome SC unit with sandpaper etc before
re-attaching the hose.This time we iced it first and also used some wire to help temporarily brace it until my shop makes it "bulletproof" this week and attached right. All told we were stuck there for nearly FOUR HOURS.still, amazingly lucky we were not on the side of the highway sizzling!

Could this really just be from the unit being chrome?? Why would they design it that way then?? What cna be done to make this right? I've heard of lips in the metal and multiple clamps but that's pretty much it. And who the hell knows how we're getting home tomorrow (4 plus hour drive). Shop just said drive easy and avoid boosting as much as possible - but hell I rally don't wanna get stuck in the Bronx at night in the shiny Roadster - or worse even, in the freakin' WOODS somewhere...OWCH! Thoughts all?

Just made it home....

Well - I just made it home!!! And safely and without blowing the damned seal again! Thank GOD! W'HOO!!! Now I get to take it into the shop and roll some heads...

To worsen matters, the clamp bolt on the newer "temp fix" clamp was BIG and left on top of the SC. Unfortunately, there was almost NO clearance and it pushed thru the hood and left a nice tiny ding from INSIDE - OWCH. Will take that up tomorrow too. At least I made it safely.

Thanks Salty. Will update as things progress...RM
