Nice set up. Is the air intake now in the right ear?

Thanks

Yes, the white tube. People says it sounds like a proper jet plane on the straights

Maybe you can see pictures in this link. Manus , the Dutch guy, has a Europa . Maybe he can give more info about it????????

Confirmed :-) Europas have no floor under the engine, but above the engine (smaller vents) it is more closed. You still need to work on extra cooling on those....

What's the filter you are using?

Also they dont have a bumper as per the Elise/exige/vx

Really nice air feed shroud for oil ic. Did you remove the fuel carbon canister vent?

Thanks!

 

Yes all of the carbon canister/EVAP bits are removed and replaced by this: https://www.merlinmo...-push-on-m-tpv8

in combination with the oem roll over valve.

 

This works really well, never smelled any fumes.

Congrats on an impressively busy engine bay!

 

BTW if your induction makes a lot of sound (like a jet engine) then it is a possibly a restriction point, maybe worth taking another look at.

What they hear is the sound from the compressor wheel, if I remove the filter I can actually see it. The plan was to get a straight pipe to the turbo inlet for optimal flow uniformity index but I had to use a bend since I wanted to keep the klasen manifold and downpipe.

Have you tried a dyno run with and without the air filter pipework? I think you might get a big surprise. Quite a few of us have had startling gains from improving the air inlet. Carsten got +30 HP on his K06 turbo car for instance, and I got +45 HP from increasing the inlet from 3" to 4" with dual panel filter airbox and I know of a few others too.

What helps the most is having the filter in this location to remove almost all bends and only having a few hundred mm of tubing and a race foam filter with almost 300mm in length, totally shielded from heat and fed air from the ear. 

At the moment I'm not limited on the air side in any way it will happily make use of the complete width of the EFR6758 compressor map. The way it pulls up to the limiter at 7700 is mental

I don't doubt a 440 HP VX pulls like mental, but how do you actually know (ie measured) that there isn't a significant pressure loss between filter and turbo?

Well, I work with designing engines inside and outside with CFD as well as real testing of different designs    And I'm lucky to have experts at hand when in doubt    So there is a reason it is how I made it, but still two small bends and a couple of details from perfect due to packaging limitations.
