Well im doing my Lid conversion(slp lid,complete lower air box and FTRA).I got a harwood ws6 ram air hood so i dont need to cut anything and i dont want to,so no cutting on the rad or the hood or the frame, etc,etc....Im having a trouble to make the connection between the MAF and the TB.Like a lot of people told me here ,i ve bought a Fernco 3inch to 3 inch coupler but it doesnt fit perfectly.So i would need help to finish this once and for all

I dont have my camera to take pics but i ve found the exact problem that i have on the board so here it is:

So you can clearly see that the maf is angle down while the tb is level

What would be your solution(dont wanna cut the lid please)?

I was thinking abour a 45degree 3inch coupling but not sure about that,i want the most smooth way possible.Link is only there for example:

Thanks

 

I have the same hood and problem. I used a straight Fernco 3" to 3" and a peice of the moroso CAI to help span the distance. I think I am going to pull the MAF out of the lid and use a small peice of silicon to space the maf out and then use the fernco from the maf to the tb

 

The stock Ls1 boot works just fine

 

Didnt think about that
I will keep this solution has a backup if i cant make it with one boot only.

Your talking about the accordion one...i was thinking about a smooth one so the flow would be optimal.

There is absolutely no true gain in the different boots but its your choice. No gain or loss at the track on my car.

 

I have a smooth one..4" in diameter..goes from my TB to the MAF, I needed the 4" cause I have a 90mm TB and the Z06 MAF.

I don't see why a 3.5" wouldn't fit the oval LT1 TB..maybe it needs to be a 4" to 3.5"..4" on the TB side, and 3.5" on the stock MAF side. I had to use one like that for the MAF to the Lid..


Not sure about which particular one fits a stock LT1 TB..I'm sure someone knows though.

 

I'm pretty sure I used a 3" Fernco on my build. It looks like it won't fit at first, but if you boil it, it will stretch out pretty good.

 

I am using one of these. Although I don't have a MAF anymore.

That's what she said..

 

lol fun fun

 

I used NO coupler from the lid to the MAF. If you try it the MAF slips inside the lid and fits perfectly. At least it did on mine. It's so tight I dont even need a clamp.

On the MAF to TB end I used a Fernco and didn't boil it. Just manned up and put it on the TB.

 

exactly what i did!

old pic from the beginning of LID swap

 

I did the same thing worked great.

 

I know it's more money, but I thought I heard the SLP smooth bellows works perfectly, is that true?

 

I can get the 3" fernco on the TB no problem. If you call that "manning up" you probaly have a worn out mangina.
The reason my MAF isn't in the lid ANYMORE is to help with distance from the lid to the TB. See, I didn't cut one part of my car up to do this( Thank You Harwood hood ) I trimmed the bottom of the ls radiator support to accomplish this and it all fell into place

 

i think most of you guys that didn't have issues with it is because you didn't use the lower ls1 support. It raises the lid alot and changes the angle going to the tb, that's where the trouble starts. I've had the same issues as this cat so I know where he's comin from. I should have the proble solved in the next day or two tho.

 

^^Yea that angle is a bitch..I have the LS K-member with my Engine, I don't know if the LS Intake/TB sits higher than the LT1..I think it may just by a little bit.

 

You got it

When you dont use the lower airbox the lid output sit at the same level has the tb.But when you use the complete assembly it make the ouptut ouf the lid higher and give it a damn angle...

 

Hey G,
I got mine working last nite, I just got another short coupler and slipped over the lid exit and the MAF. All is well, the car screamed up high last nite!!!
