I know it's been discussed, but I was hoping to have a better understanding on the matter. I've heard that as the car gets closer to red line/fuel cutoff the throttle flaps close to ~40%. I never really noticed on spirited runs, but I've noticed more recently against various friends (Pacific Raceway). We had the opportunity to run in a straight line. I'm concerned as to WHY I'm always the first to fall behind once we start running into triple digits. The 335i I can understand (JB3 @ Map3, Ark DP's, Intake). Our TL-S 6MT on the other hand, is a bit baffling. Yes, he's essentially fully bolted (UR Underdrive Crank Pulley, V3 J-Pipe, V2 Precats, Injen CAI, Comptech SS, [Resonator deletes], Light weight TE37's) on and thus has a better breathing car @ higher rpms, but it's rated at 286 crank hp; I'm supposed to be lighter too. I'm essentially stock, minus the Injen cold airs, performance wise. Is it really the throttle flaps that're running me down? Osiris?

Thanks coupes,
Eric

Note: Closed runway via Pacific Raceway in Kent. Topic is safe, yes Mods?

 

If you want more top end get CAI.

 

He said 'I'm essentially stock, minus the Injen cold airs.'

 

sweet.

 

bbuummmpppp

 

another bump

 

You fall behind because the G is a slower car than a 335i when you get into tripple digit speeds.
