Ok I have been thinking about this today, is there any reason that I cannot put my throttle body after the blower with a twin screw? I know that I will have to move my vaccum referance for the by pass but..... I was thinking of putting the MAF and the throttle body after the blower actually between the intercooler ( Air to Air) and the intake manilold. With the MAF in the stock location before the blower it seems to me it would be less accurate because of the fact that some of the air that it is metering is being bypassed. If the maf was after the intercooler then it would be reading the exact amount of air entering the intake. Any ideas here? Or am I just being stupid.

 

I would not worry about moving the throttle body. As far as the MAF goes, as long as you locate the iat sensor after the intercooler you wil be fine. If you can set it up to move the entire MAF after the intercooler thats fine too.

 

Well the reason I was thinking of moving the throttle body also was so that it would eliminate the problem of sucking silicone elbows closed and with it being on the boost side the downfalls of the 78mm throttle body would be decreased. My IAT will be right before the intake manifold. I have just been thinking that maybe some of the reasons for tip in knock on twin screws may be due to the MAF reading Vs. what the engine is actually using. I dont know just thinking outloud I guess. haha

 

Just thought that moving the MAF may make tuning a little easier.

 

My truck ran a helluva lot better when i relocted my MAF to the boosted side, granted I have a Turbo but I think reading the boosted air flow has to be better then a draw through set up...

 

IMO.. i wouldn't put the maf sensor after the throttle body. i've also never seen a twin screw setup that blew through the tb and maf so i guess i'm no help at all

 

Niether have I, however I am not sure what would happen? This is why I was thinking of doing both the TB and the MAF. For now I am just going to leave it as is when I get the intercooler on. The IAT will been right before the intake manifold, it was just something that I was thinking of and wondered what everyone elses .02 was. Paging Parish......

 

i dont see the benifit of moving it. being that the twin screw is a positive displacement blower i wonder what would happen when it is pumping along at wot and the throttle blade slams shut. you could do a bov for it and i am sure the bypass would kick in somehow too but why mess with it when you can get a 90mm throttle body.

i do like the idea of moving the maf to after the blower if you can do it. there has to be a little restriction pulling air thru that thing.

 

Well putting the MAF between the intercooler and the intake would be easy. Is it ok to have the MAF after the throttle body? I dont think I have seen it after before, wasnt sure if it would cause any problems. I think I will leave it as is for now until I get the intercooler on and get it tuned right for the intercooler. Then maybe Ill try moving the MAF and see what happens.

 

I was going to try this but got worried if the TB slammed shut at WOT Also the blower resonance would be pretty BAD.
