Mishimoto - MMCLAMP-25T Stainless Steel Constant Tension T-Bolt Clamp, 2.5

Clamp works good at the moment but it's not what's on the picture.On picture we have a constant tension type clamp due to string which is what you want at high pressure intake systems. But what came is normal type clamp. One pays higher price expecting a better product. There's plenty of other good clamps without constant tension spring for lower price.

Clamp looks to be of high quality. Installed it and so far has gotten the job done.

Item arrived on time and as described. We used this for a custom air intake system on my sons Ranger that we supercharged.

Tension T-Bolt Clamp. 3inch. When turning the 10mm nut Seems like it tightens right away. Anybody who uses a torque wrench will understand what I mean. Then my ss pipe slide out of the pvc hose..hmmm. that is why I bought this because my worm gear is doing the same thing..while it was separated i found I could twisted the tbolt clamp and it rotated. Wasnt on as tight as it appeared.. Put it back together and kept tightening. Seems to work. This is between the turbo and tbi housing..upto 19psi.

Looks great, great idea. But good intentions don't make this a good clamp. I'm using two of these to secure a pipe coupler from my intercooler to the upper intercooler pipe. So far, if you tighten the clamp down tight enough that you can't budge the pipe or move the clamp, what feels the same as with a well tightened cheap worm clamp, the coupler will walk off the pipe under boost still. If I tighten it just a few turns tighter.. It begins to buckle the pipe or dent it where the two pieces of the clamp meet and are covered by the thicker metal piece. So either it won't stay on and hold boost, or it's so tight it damages the pipe. And it's not cheap pipe, I have a K&n typhoon intake. These clamps are so far not even able to deliver the same quality of performance that a $1 worm clamp will provide.Update: Had these on a week now more or less. Have had to stop and replace pipes popped off the charge pipe twice now on the side of the road. The springs look heavy duty but immediately compress in size the first time you tighten the clamp. So each time you loosen or re-use the clamp the amount of tension applied reduces. At this point, after taking off and putting on this clamp a few times...I have to tighten the clamp down until the spring is fully compressed (ie: pointless now, as it cannot expand to allow thermal expansion to happen as intended) in order for the clamp to remain tight enough to handle normal boost pressures (26lbs of boost). Reducing the review to 1 star, these aren't worth the metal they're made of.
