I was doing some thinking and that's what I feel would happen. The BOV would release all the pressure into the atmosphere but the MAF read a lot of air going to the intake, so ECU dumps fuel. So you run real rich for during this time which I think would cause backfire. Which would in turn spool the turbo up right between shifts.

Sounds like a mis-firing system. I'm probably wrong but it just seems like that's what would happen to me.

 

Yeah. It causes an overly rich condition.

 

Yeah just ask a DSM guy about venting their BOV lol. I bet they all have big soft ones for MAF systems.

 

i know how to do it without an over-rich condition.

 

How?

And wouldn't it be nice though for it to work this way say if you had a big turbo and spooled slowly? Then with this, you get a nice spool before you put it in gear. :P

 

There are divices for that.. can't remember now what they're called - but I think they call 'em launch controll.

But, how they work: you press throttle, it keeps revs at ~4000rpm - BUT, it throws in more air and more fuel. Now - you ask how comes revs dont go up? Simple... ignition is retarded - WAY retarded, dont know exactly how much, but numbers are like 20degrees - thus even big part of combustion is in manifold itself. Due to enuff air&gas you get again lost of exhaust gases which spool turbo, even while in neutral.
Yes, this works... and yes - it's not too good for engine, as there is combustion in exhaust manifold, etc, etc... but for 1/4mile and other drags when you need fast start - they're awsum - especially if you have 4x4 drive!

 

Its called Anti-Lag. Rally cars use it.
