who here has welded a vband to a stock tb. Any pics... and what size aluminum vband did you use for the job. Using silicon and tbolt and it wont stay on at 25+ psi now. Want something to solve the problem for good.

Have you considered welding a bead around the TB so when you clamp the T-bolt on the engine side it has less clearance to work it's way past? We used that tactic in my old TA and it worked great.

A good bead and clamp should hold lots of boost. Ensuring all surfaces are spotlessly clean of course, maybe some hairspray to help them stick.

Or a bolted brace across the two sections of metal to secure them together so they cant pull the silicone coupler apart.

ie this sort of thing

Or this style of clamp is popular and allows some flex at the joint, Wiggins type joint

There seem to be cheaper versions on egay etc, search clamshell clamp, pegasus clamp

Here is mine. IMO I think it looks super clean and no way to blow apart.

Granted it's not on the stock intake and tb.

I have a stock ls1 throttle body with a 4" vband welded on and an 4" aluminum elbow with the other vband on it. I bought it from a member on here but switched intakes and can't use it. ( need an ls2 style throttle body. I will sell it cheap. It needs cleaned up. He put a black wrinkle finish on it. The elbow reduces down to 3" after the 90

Just weld a bead onto the TB,
and add a strut/brace from the engine to the intake piping with a Rod end/heim joint style adjuster

stock TB, silicone boot, t-bolt, & hairspray. 30 psi + with not an issue.

I used to blow boots off of my diesel truck at 40 PSI...used the strut rod method on the pipe to pipe...would be an easy alternative to buying an expensive v-band.

Plus, you will still have the flexible properties of the silicone boot using a strut bar.

All these joints/braces etc. are completely over kill. If you want to just weld a bead on the TB that would be a good idea but with a properly sized boot and a GOOD clamp you shouldn't have to worry about secondary clamping methods untill you get into the 60+ PSI range. Clean your pipes and make sure you have quality stuff and try it again. I push 55 PSI daily in my F-250. I had this happen a few times in the past and it was nothing more than dirty pipes and crappy equipment.
