In theory yes...but a few variables. Ultimately, silicone shouldn't be popping off ANY tubing unless over pressurized,..IE 60-80+psi or lack or bead roll, lack or proper clamp...wrong clamp..etc...but silicone should hold up for everyone here on this site...given it's proper silicone and not some elastic feeling cheapy stuff.

Well heres my dilemma. I have a 102mm tb (4") Its billet aluminum. Going into tHe cold side piping, which is stainless. I can have the stainless pipe welded to transition cone, but does the clamp get welded to the actual tb? I cant weld stainless or mild steel ( cone ) to the throttle body.

So you just do one side aluminum, one side mild steel. Mild steel obviously will weld to the stainless. No problem. At all.

Here is mine on a stock TB. Didn't even heat it up enough to pull it apart to weld.



instead of aluminum/aluminum...aluminum/mild steel for you if you wanted to go that route.

Your the man! Is it best to call or go online? Or can i go through you for this custom mild steel/aluminum clamp?

best just to call bro. Jamie is my name, just remind me we talked here, or just tell me what you want. We try to do what we can for the bullet or tech fellas the best we can. Just gotta tell us.

Where do you get a good quality T-Bolt clamp these days that doesn't bend or shear apart when you apply some serious torque to it to seal up a stubbornly leaky silicone to tubing connection? All of them I see from Vibrant and whatnot look the same construction as the shoddy ones I get from eBay...

Also, does the hairspray help seal too, or is it really just for assisting with grip?

I get good t bolt clamps from the local peterbilt dealer. They usually have multiple different sized in stock and they are badass enough to be reused. I haved the same set for the last 6 years no problems and torque the hell out of them.

Do these clamps need to work with a bead weld on the pipe to pipe? Or can they be smooth? Maybe thats a stupid question...

Tjabo

Good tip on the peterbilt dealer, I'll have to see what I have around here.

I got some name brand (made in Mexico) ones at carquest today, and they look like they might be marginally stronger than the eBay specials. Gonna try them out.

stevieturbo

Why on earth are you trying to apply "serious torque" to them ?

What sort of boost are you running ? 60, 70, 80, 90psi ?

Tjabo

Attempting to get them to seal in 20psi from the boost leak checker.

stevieturbo

If you cant get a boost pipe to seal with even a cheap worm drive clamp at that low pressure, something is seriously wrong.

And the last thing you need is t-bolt clamps, which make it all too easy for people to over tighten them and cause damage or leaks.

Tjabo

I think the fact that the worm drive clamps sealed in every spot I tried them where my garbage T-bolt clamps wouldn't seal kind of illustrates the actual problem.

Sounds to me like you have never dealt with some of the sorts of crap T-bolts I've been getting from eBay lately. That and maybe my description of the torque I want to put on them is probably a little bit of over-exaggeration..

stevieturbo

I've no idea which clamps you are using so who knows, there are many designs, some good, some bad, some just rubbish.

But I've seen idiots actually crush stainless steel tubing from overtightening t-bolt clamps !! So the description may not be an exaggeration because I've seen people do it !! And to to what he did to stainless really must have taken some effort, and surprising the threads on the clamp didnt strip.

But on a good clean joint, with a decent bead of some sort whether formed or welded, a good worm drive style clamp will hold a lot of boost quite easily. Now once up to say 4" where forces will be larger, then a better quality or stronger clamp can be needed. But below that, especially at low boost there should be no difficulties

my evo is all 3' piping with a mix of cheap worm and t bolt clamps and it holds 32psi no problem. ive seen a lot of problems when the ends of the pipes dont line up right and the clamps and couplers are at wacky angles
