Hmm would think 48 mm is a little small for a 3.8 seems 50 is a better choice at least for a track Porsche with all your mods

I wonder how durable the rp intake runners are.

Shaun @ Tru6 08-12-2018 11:26 AM

Can you please post a few pics of what's under the foam and the underside of the foam?

Hey Shaun, I only have this pic as I’m away from the car at the moment. I’ll get some more pics in the next week if you’re still keen.

Thank you, this pic helps. Interested to see how the foam fits over these.

Hello TAV - the trumpet design looks very different from the ATPower ITBs I have seen which have the usual vertical stacks. What’s the reason behind the curved intake?

I’m guessing to tuck the air cleaners further back to allow the decklid to close

that filter setup looks great. what pattern is the base plate? i.e. is it made to fit the old weber pattern manifold?

Apparently they did some testing with different Inlet tube lengths to give a preferable lower end torque as well. The length they came up with would not fit in the engine bay, hence the curved inlets.

The engine build and management system is by Rasant Products in Southern California. Cam is GT2 Evo with 108 center. Pauter rods, 10.5:1 CR. I don't have the ITB size at hand, I'll look for it.
