M2 Intercooler Mounting
I recently installed an M2 medium IC, and have a quick question for others who have done the same...
So far, I've done nothing to secure the IC in place. From what I can tell, there shouldn't be any problem with fore/aft movement - the duct keeps it from moving forward, and the forward-slanted angle of the IC resting on the crossbar keeps it from moving aft. However, it doesn't look very stable against lateral movement. I'm sure the pipes/couplers will resist this movement somewhat, but I don't feel very comfortable relying on them to secure the hefty IC. What's more, I don't want to transfer those forces to the intake manifold or Y-pipe. I also have a relocated battery, so there's nothing to the driver's side of the IC to keep it from moving. The flimsy Pettit heat shield on the other side certainly won't provide much resistance either...
I'm thinking of fitting some small brackets to the crossbar on either side of the IC to make sure it can't move side-to-side. My question is, has anyone else done any research on this, and if so, what did you find? Is the movement a non-issue? Or did you fab up something to secure the IC?
FWIW, my concern here is for track use - I seriously doubt that this would be a problem on the street...

I've used an M2 Large SMIC for years at the track with no problems. The only thing I did was put a little foam padding at the bottom to prevent metal on metal rubbing. Other than that the intercooler pipes keep it in place tight.

I've got the same thing as John^^^ and had the same concerns as you. I got hold of Kevin from ASP (same as M2) and he said if you are really uptight about movement, some folks have used velcro on the frame and intercooler. I didn't use anything and it seems to stay put, but, I've only tracked my car once - but it is my 4X per week driver.
BTW, didn't you sell your track car last year? Are you building another?

I really think you're worrying about something for no reason. One end is on the turbo/y pipe and the other is on the intake.... all held together with beefy clamps and fat hoses... I've SAT on my intake before... I don't think that the couple pounds from the IC are going to do any damage heheh.
Velcro is an excellent idea if you really want to do something, but my only concern there would be that the adhesive would melt.

Thanks for the input guys. I think I'll just let it be for now, and address it later if it becomes a problem.
Very good point. Securing the IC too well would certainly create different stresses. More flex in the couplers, in addition to bracing the IC, seems an ideal solution.
I previously ran a PFS IC/intake combo, and with a battery in the stock location, it was a real tight fit. No room for any movement whatsoever, but I was using the "hump" couplers with it. Nice, solid setup!
If I had a battery in the stock location on my current car, I'm guessing it would be a similarly tight fit. Instead, I have a big open space to the driver's side of the IC. Plus, the Pettit intake heat shield is so flimsy compared to the PFS box, it won't hold up to much force without allowing movement. That was what made me think of making some brackets...
Of course, if others are running this setup on the track without any problems, I'm not as worried about it.
Yep. I sold the racecar and am now building up a street/track FD. I bought Joe Ramos' old car from Fritz - it's in fantastic shape for the most part, and should make a great track car. I'm hoping to have it ready in time for the G&W event at VIR.

I think that brackets (if you make them) should take that into account. Or you could make the joint between the IC and engine more flexible by using hump hoses instead of straight hoses.

You'll have to forgive FDNewbie. He doesn't have a clue about much of anything other than what he reads on the forum.
As others have mentioned it's not going anywhere and it actually will put more stress on the manifold and Y-pipe if you try to do a hard mount. The engine rotates with load so if things are bolted to the frame and the rotating motor it's going to flex either the couplers or other less desirable locations. The only real issue to consider is the long term metal on metal rubbing undeneath. As mentioned above a good solid piece of $2 velcro will resolve it. Remember there are over 400 of these in use, many for almost a decade, nobody has ever had a problem with lateral movement that I'm aware of.

BTW, I was seriously planning to buy a new IC from you, but I came across an excellent deal on a medium unit on eBay. I got the pipe that clears the air pump, but it's not the newer cast pipe. I was wondering if the cast pipe gives more clearance than the older-style pipe, because mine doesn't really clear the air pump intake hose. Any thoughts?

ok, there are two phillips head bolts to the airpump. You can either rotate the whole tube 180 degrees, and get the hose to the airbox (I have the m2), or you can do like I did (kinda getto) and take the bolts out of the tube, get it turned where it fits best, and then grind the sholder enough to get the bolts back on to secure it down. I don't think it needs to be a perfect fit, it is the suction end.
Note: my bolts were tight and I had a hard time getting them loose with a screwdriver - use an impact driver to remove them.
