so...... dumb question here......probably been asked a million times before aswell, but its sunday morning and im bored so im gonna ask it anyways.....

what is the technical performance difference between the split and the bell mouth? appart from the obvious different design, and i dont mean power figures.

like faster spool with one over the other.. or one makes better power when at full song

would the extra turbulence from the bell mouth setup really make a difference? or are the differences with the split only noticable when running really high boost levels ie: 20+ psi therefore making it wankfactor status to the general skyline user.

sorry to drag up an old thread but rather then make a new one.

i have the same dumb question as above, is it worth forking out extra of the split as opposed to the bellmouth. i'm just a daily driver who give it abit every now and again, standard boost and that prolly wont change while i have the car.

looking at getting the Xforce mild steel 3'' Turbo back system http://www.xforce.com.au/cars/view_car/13

thanks guys.

    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
    • There is an ABS pump and a few solenoids. You could trigger the front/rear solenoids with a pressure bleeder attached with a Consult 2.
