Okay, i know that the fast doesn't have very good quality when it comes to the map sensor location, and thats fine. I already bought the intake, and i plan on keeping it. My question is what is the best way to make sure the map is sealed up. I have the intake on the car and i think i have a vaccum leak from the map. I just used Rvt the first time i installed the intake, but I thought about using a rubber grommet in there try to make the hole smaller, i have heard of people taping the hole and putting a hose end in there and then use a rubber hose to the map. If anyone has suggestions or other ideas or have done either of these themself some guidance would be appreciated.

 

Here is a pic of what I did. Works well with no leaks.

 

is that a 90, cause i don't think it looks like the 92mm intake that i have.

 

Come on guys, i know there are a lot of people out there with the FAST intake manifolds.

 

i did what DrkPhx did plus rtv

 

Teflon tape is definitely NOT the way to go.
I think I tracked down my stalling problems to a loose MAP last night.

I like DrkPhx's idea but I'd have to pull the thing, and that job sucks.

Also, I'm guessing there isn't a difference in the 90 Vs. the 92 in this regard.

 

wish i wouldve seen that before i put my fast on, i dont have any problems now, but when i put the map sensor in i saw the potential for them

 

Mine ran fine for the 1st season, this year it was wobbling all over the place. I think the teflon tape just broke down. It was pretty snug when I put it in the first time but I think gradually...

Lesson - do it right the first time...

..where have i heard that before?

 

Yes it's a FAST 90mm, but it's painted black. Post of a pic of the back of the 92mm version.

 

Alright i will post a pic when i take it off tomorrow, i am two hours away from the car right now, at school in eau claire, WI. How far is St. Michael from the cities DrkPhx? I would definetely like to check out your rides sometime. I am moving from rochester to cottage grove the first week of june.

 

It's pretty far; about 35 miles northwest of the metro area. I work closer in town.

 

Isn't there an alternative MAP sensor that fits better?

Mine was working great for over a year, then started to hear a whistle as low map areas like idle and deceleration. With some throttle the whistle would go. So i tracked this down to be a loose map sensor on the fast intake. I took this off and used some tape to make the map sensor a little bigger and make it fit in the hole then used some sealant and plumbed it back in. I thought the job was done better than ever before, but not is starting to whistle again 2 months later.

If there is a map sensor that fits better I'll invest in one.

 

I used a piece of lock wire to hold the map sensor down tight. I used the bolts as tie down points.

 

RTV worked fine, let it set over night.

 

Here's my FAST 92mm... I haven't installed it or tried fitting the MAP sensor, but it says "REVISION J2" on it. Sorry about the quality, camera phones suck.

Hope these help.

I think I am having the same problem right now. I am going to use rtv and see if i can think of a way to hold it down.

 

RTV here, holding up fine. And my 90 said 'revision J2' on it as well.

 

Here's what I put together..


Only took about 10 hours and 5 or 6 trips to HomeDepot and Menards.
I feel much better about that than just some RTV, but I had the old style FAST.
Fixed ONE of my idle issues.
