BEAMS and factory ECUs - questions? update: 122Kw at wheels

[The Witzl]

dude that is some awesome power from an otherwise stock NA 2L engine.

yeah, I'll hopefully see it drive in anger at Qld Raceway on Wednesday.

I think Graham will be thinking about things like brakes and suspension soon

His back-of-envelope calculations suggests ~210hp at the flywheel. I haven't seen the dyno plot but he said about torque "curve looked good to me, small deviation at about 6000rpm then flattens out at 7000-7500" . He also mentioned that Anthony had recently tuned a BEAMS with ITBs and it got 128kw/wheels so 122kw is a good result.

It's a big step up for graham as the previous track car (RA40 hatch versus this RA40 coupe) is a gen1 (with gen2 head) 3SGE with factory ECU.

Awesome result - I've just started taking my Beams RA23 out to QR and Lakeside, so hope to see Graham out there at both sprint events. Should also be pretty evenly matched capability wise so will be great comparing times.

edit: Mine is running stock ECU so will also be interested comparing their outputs. I haven't had mine on the dyno yet, though will see what I can do about that.

End of last year I tuned a BEAMS with ITB's, 110mm ram tubes and adaptronic on a Mainline dyno, ended up pulling 139rwkw.

Talk to Glenn about the power he is getting out of his NA Beams engine in his RA40, a lot of devolopement & extensive dyno work has been done to it & i think from memory he said he is getting around 180 plus RWKW !!!!! .. Quite amazing ...
