So, which efr turbo are you running? Is it a one-off setup you guys have built?

ADF Motorsport has built the cars. Ive only been involved on the Motec side of things.
There are a lot of N55, N14, N18 and also a N20 running on Motec M182s and M142s. Ive done most for ADF Motorsport and also for GH Transport. GH Transport is running N55 with Garrett turbo. It makes at 1.1bar just over 400kw. The dyno graph i posted long ago is now at 471Kw, more boost. Hasnt given up yet. All stock internals still. GH also runs 2x S54's on M130's with good results. One S54 is sequential g box with gearbox control done with the MJR S54 M1 package. It does downshift rev matching on the clutch less downshifts between gears. Lightweight S54 engine with the ITBs makes for an engine that works well in transitions and therefore downshift strategies. I think i would post the S54s and 135i N55 on other threads if someone was interested.

The N55s mostly run EFR76's and bigger. I think ADF ran a 70 too in one car. Cant remember what Garrett was in GH N55. I prefer EFR so far. Will do a Precision on N55 soon

Martin,

Can you tell me more about the N20 engine project?

Thanks

[Martin]

Got N20 running for a long time already. Similar to later N55 versions as far as DI Pump and trigger patterns. N20's come in various levels, there are mechanical differences between them such as cams.
