so knowing that i, and others, in the future hope to play a fun game of how much boost can i make from a roots blower, let's discuss...
swaps that have been done in the past:
- whipple
- MP112
- M112 hybrid
- TVS 1320 (yay, flake!)
- and of course the uber popular and BORING, genV swap
there are probably others because not that many people like to promote their setups on the interwebs like we do, but that is neither here nor there.
now, there are a few options for how to adapt a new blower onto the stock lower intake mani:
- adapter plate
- intercooler that doubles as an adapter plate
- destroy the lower intake and find a way to bolt it directly on (not that bad of an idea, really)
problems that a blower swap poses:
- outlet on the blower does not line up
- pulley/snout are in the wrong position and does not line up
- throttle body wont bolt on or be useable without an adapter (fairly easy to mock up)
- blower is massive and you blow your heads off the car (oh god that would be awesome)
now, here is where you all come in...and me when i get around to it or if i decide it is a good idea to buy parts and play.
i find the biggest problem is the pulley/snout not lining up. a lot of the aftermarket blower vendors do offer different snout lengths, so that may or may not be an issue.
the next step is to locate the outlet on the blower to a good position. i dont find this to be a huge issue considering that you can use a slanted transition in the adapter plate. of all of the outlets i do not think this transition will have to be that big, but that all depends on the blower of choice. knowing this it brings into play a valuable concept: boost is boost is boost. regardless of how the air coming out of the blower flows into the lower intake, the lower intake will still pressurize and distribute the intake charge between the cylinders as it always does. this means that the outlet being slightly offset may not cause any issues. again, how much overlap you'd have depends on the blower that is chosen for the swap.
the throttle body adapter will never be that difficult. if you cant figure this part out then you're already screwed.
now, let's play devils advocate and start picking blowers that would be a good fit for a big build. blowers that have been done are all good and fun, but i would love to have a setup that is more one off. nick (blue) and i have been saying that a nice kenne bell blower would be the hellaciously cool, especially considering a few of them are water cooled (built in intercooler baby!). remember, this is mainly going for a cool factor (for me at least) and lame groany old man whines like a whipple are weak sauce to the max, regardless of it making 550whp.
and yes, this thread has rules. off topic? deleted. stupid comment? deleted. fighting? deleted. DO NOT SCREW THIS THREAD UP, THIS IS A SERIOUS TECHNICAL BUILD.
now let's play.
