you said something about drillin a 9/32 hole in a mr gasket replacement for the iac. you mean replace this gasket and change these holes (c) to 9/32

Casper98GT · February 27th, 2007, 04:43 PM

yeah that gasket right there. Good pic for those who dont know what it is im talking about.

If you look on the plenum there is only one hole. Drill tghe 9/32's for that hole. Then if you want it to come down faster or slower...drill bigger or smaller on the other side. Make a bunch and mess around with it.

i guess ill give it a shot. see what i can do

speeds up or slows down the drop of the rpms when you rev your car depending on the size hole you choose.

How hard is this to install?

I bought the restricter too but haven't put it on yet. Was it a huge difference?

Looks like I need to put it on before I get it tuned this Friday.

Its so simple! YOu take off the IAC and put the new restrictor on! Put the IAC back on! I dont know if you need two gaskets thou! One for in between the plenum and restrictor and one in between the IAC and restrictor! Will take all of 5 minutes! And while you have the IAC off I would recommend that you clean it!

If your racing though you dont want your RPM's dropping off quick. You want it to stay in the rpm band.

Dennis · May 1st, 2007, 10:45 PM

ok are you drilling the mr.gasget to that size or the iac itself im a little confused here

MustangMatt96GT · May 1st, 2007, 11:07 PM

No he bought the actual metal plate on to go inbetween!

Really... I didn't think of that. Maybe I won't install it after all.

MustangMatt96GT · May 1st, 2007, 11:33 PM

Yeah that is why I havent done it to mine! I just neglected to say anything about it!

ujslost · May 2nd, 2007, 12:13 AM

dont know about you guys, but reving down dont mean shit to me. but my car revs up quick as hell compared to the 5.0s i have delt with in the past. must be those overhead cams!

Dennis · May 2nd, 2007, 08:57 AM

ok ill try again the origional post talks about mr gasket and drilling 9/32 holes thats what i was refering too are you drilling the gasket orthe iac

Casper98GT · May 2nd, 2007, 09:43 AM

you make a copy of the gasket and drill holes in the gasket. If you mess up just do another one..

And you do want the RPMS dropping quick when youre racing BTW.

Dennis · May 2nd, 2007, 04:12 PM

So... it IS good for racing? I misread that and had to double back.
