New intake system, Made by Mario at the dub shop Options

[Henshe]

Mario, of the dub shop (thedubshop.net) fabed up an awesome intake for the 914. It looks great and now I can even hear the Tangerine Racing exhaust over the itb's. (IMG:style_emoticons/default/piratenanner.gif)

How about:

Loose the ITBs, attach the intake directly to the manifolds, and source a single throttle body from a 3.2 (or similar).

Then, it's a mod with a purpose and there's no more linkage debate.

I'd actually like to see something very similar, except with a single Ford mustang 70-75mm TB. Of course that would need a 2270cc
I just would like to know what the performance difference would be over ITB's. (IMG:style_emoticons/default/idea.gif)

The last time I did a comparative on a similar set up (with an even larger tubing ID) the engine lost 11HP and almost 20# of torque.

Air cleaner setup like posted or throttle body placement like Mark mentioned?

Almost exactly like this. The approach path of the air into the carbs favors one cylinder more than the other, among other issues.

Ended up going Tps for the ecu anyway so I took it off again.

Going OT...what ecu are you using....I'm on SDS & could never get a good mps with the 2316 on itb's so have been on tps & it's fine. Uses closed loop for cruising, & seeks 14.1 afr nicely.

That because of the ITB, not the ECU.

Basically that was my question in part because of MPS signal issues and the intake noise.
In my case at a ballpark 180hp, losing 10hp in a street car wouldn't be that big of a deal.

This is in my bug I will be also looking at my A1 exhaust to see if I can quiet it down a bit. I guess I'm getting old.
