so i will be installing my TVS here in the upcoming days..and ive heard that you have to grind down the MAP sensor so the TVS will fit? how do you do this? or can you just move the sensor out of the way? any help would be greatly appreciated..especially from people who have a TVS on their ss thanx

 

its the MAP sensor on the intake manifold. you have to grind down a little where the bolt holds it down. then turn the sensor clockwise and the blower will hold down the map sensor

 

good catch..MAP sensor .. i edited the original post..how do i grind it down??

 

a file will work. i just took it to a grinder.

 

You can notch the hole enough to rotate the sensor AND get the bolt back in it.. i prefer to have it bolted down, even if the sc holds it

 

how long did it take? and can it be an easy job in the garage? id have to locate a grinder

 

take a dremel, and open up the head side of the hole (slot it) so that the angle support behind the hole is gone, so you can rotate the sensor from the 12 and 6 o'clock position (stock) to line up at between 8 and 2 or 7 and 1 o'clock, it has to clear the tvs and not run into the radiator hose. Be careful, I cannot send you piktars until next weekend and you will have to pm me i cant post them up. hen make an alloy tab underneath the hold down bolt I think it is a # 5 external torx (cant remember for sure) to locate the sensor properly.

 

howd u notch the hole?

 

theres a how to pretty sure... or atlest there was

 

i cant find it if there is... if someone finds it if theyd post the link thatd be helpful

 

I actually used a pair of side cutters and a file..lol

Not mine, but a picture of someone's on here

 

lol hey whatever gets the job done right..im just hopin its not a real snag in the install..

 

heres what i did, i also had to grind down the other side cuz i have a chrome rad hose a and the map sensor wouldnt have enough room...but this is what u need to do...

 

so do they just cut the plastic down to rotate it? and thats it?

thanx snake..good picture of it.. so basically.. to see if i have this right.. i cut and grind down the plastic around the hole so i can simply rotate the map sensor out of the way of the TVS?

 

yes....if u see where i grinded down the bottom part...thats so the tvs will fit in there....the top part that i grinded out is actualy the new hole for the bolt to hold it down

 

correct..

the sensor has a nipple that sticks down into the intake, but it's round and o-ringed, so just rotate it

 

ohhh ok.. so i shouldnt be worried about havin to do this then? made me a little nervous at first.. i also thought i was grinding down the metal around it..not the actual plastic piece..

 

correct..

the sensor has a nipple that sticks down into the intake, but it's round and o-ringed, so just rotate it

 

i thought i was gonna have to be grinding into metal.. not the plastic piece lol i feel better

 

u still have to do some grinding....yes that nipple will rotate but unless u grind down the extra plastic...the tvs will not fit right and u still have to notch out a new spot for the bolt...otherwise your sensor will come loose
