You can run one of those plastic low pressure fuel filters to help clean up the noise as well.

I'll probably end up running a hybrid MAP/Alpha N setup once I get it on. It's an easy switch with megasquirt ;)

The whole reason for the vacuum manifold is to try and even out the pulses from each runner so I get a clean MAP pressure to the megasquirt. If that dosn't work then I'll swap to a hybrid Alpha N map, and use the TPS for low RPM/MAP areas.

what are you going to do for tuning?

Going to run a blend for the signal? Its hard to get a clean signal from itbs with a map sensor.

Ya I'm wanting to try and put some sort of stack on the end of the runners inside the plenum. I'm not worried at all about the worm gear clamps in those areas. On my current setup all the clamps are worm gear and they all hold up fine. I only have one pipe that tends to pop loose, but that's becuase I need a silicone bump hose in that location and I just have a straight coupler. So it has a lot of stress on it. And FYI the Phillips head screws are All OEM BMW parts, I could replace them all with m6 bolts but it's not worth it.

Thats friggin awesome dude. I love the set up.

One or two things i dont like. Id say with N/A the normal worm gear clamps are fine. When you get boosted they might be a problem especially cause there are so many. Id do t-bolts or at least the lined worm gear ones. And the phillips head hardware makes it all look cheap.

Just my 2c and all in all this is a super gangster project and looks like it has a lot of potential :)

Good luck and i cant wait to see how it turns out.

Damn, that is gonna be fuckin tits once its installed and running. A few things about it are confusing me but it looks great.

Woah, sick work Ely!

Hmmmm. We have CBR ITB's laying around the engineering club's shop cause we are not allowed to use them on our formula car. And my dad just gave me a spare m20. Wheels are turning. Are you planning on running velocity stacks?

Vacuum manifold plumbed in



Hey if you want to duplicate it go for it, I will say the parts are very hard to find and not cheap. Most of the Bike throttle body sets sell for $300-$400 and you need 2 sets.

why not drop map and shoot for alpha?
that setup looks like it could pose problems

manifold adapters? I just cut up a stock intake manifold and machined the runners to be round on the outside.
Thanks Dave, Ya everything I've been doing has just been with a drill, drill press, grinder, and sawzall. If i had a Mill and lathe in the garage i'd be making some crazy chit. I should of gotten around to making some stuff at my old job, but I was too busy working, and making parts for the machine we were building.

really? well now i feel stupid. haha. would you mind if i duplicated your design?

I may have it on the car very soon, at first I'm going to just run it NA, while I get the throttles all synced up and the kinks etc.. worked out and get it ruffly re tuned. Then dump back on the supercharger and up the boost. I have everything made to where I could stick in on NA, and just put filters on each runner

Looks awesome, i can't wait to see the finished product!
