Can someone tell me what size of clamp I need for the throttle body? I keep blowing my coupler off at 10lbs. The clamp I have now is 4 inches..any help is apperciated.

scuff the inside of the coupler and the outside of the TB. use the cheapest rotton smelling hairspray you can find, glue it on.

+1 for hairspray, used it on my Evo couplers running 31psi

o, if your coupler doesnt fit on tight with out a clamp, get a new one that does.

Ok thanks but does anyone know what size they have been using?

I use cheap stainless hose clamps, then tighten down the screw section with channel locks so that the slot the band goes into barely fits and when tightened it will not slip or strip.

whats being called the adjuster crimp, in this pic.

I use either a 4.25 or a 4.50 inch Clampco T bolt clamp on a 4" coupler for my 102 TB and it holds 20+lbs no problem. Brian Tooley sells them as well as several other shops.

Didn't I send the size options?
And didn't you say your clamp was bottoming out?

We use 4" on most kits. No issues reported.

I got the sizes but I have a 4 inch and it's bottoming out.
