I like to drive like an idiot
besides i have 150k on the clock, so its not gonna hold up well, sure it MAY but im cool with 320

anyone think this wastegate will fit on a greddy type BOV flange?

aka a wastegate JK

i had thought about this idea when i had a vortech on my b16 si but never had the balls to go for it. i had thought about a smaller pulley to bring more boost on lower rpms but use a wastegate to keep boost under the actual pulley psi rating
...... idk about the idea of controlling boost by rpm but im sure you could have something electronically controlled thatd be pretty simple. kinda like a shift lift on and off signal which could have a solenoid open the WG from a set rpom and above.

 

i dont understand why there isnt a slipping/locking clutch pulley out et?

ya know, a one sized diameter pulley, but inside, a series of 2-3 different diameter slipping clutches that will engage/disengage for different boost levels. use one belt and pulley for like 4 different boost levels and have it all self mechanically controlled.

like a clutch-type LSD for your boost levels. lol

 

the amg e55 sc motor has this. from what i have read, it fails.

 

seems like a wastegate and boost controller for tunability would be easiest

 

does anyone have a 2 bolt wastegate and greddy type bov flange that could see for me if they will match each other?
in other words could i bolt a wastegate to my greddy bov flange

 

I just happen to have a tial 38mm wg & greddy BOV in my garage.. will check when I get home for you

 

 

This all sounds like a great idea, but there is one BIG problem with this. Timing. Running that much boost at low rpm on an s2000 requires substantial timing retarding which you cannot provide with the stock Comptech system. Running meth injection is an alternative, but with my experience trying to get the timing of this system to inject that early in the rpms when you would need it is unreliable at best. 9psi is the max I have found you can run with the stock comptech system without detonation to the motor with the stock timing map. Whether you bleed boost up top is irrelevant. To sum things up, you will destroy your motor from detonation if you run it this way and the added IAT will help solidify this without an upgraded heat exchanger or fmic.
