And so have Kewish replaced boxes that have failed also.I think the full story is this: These 4 speeds are weak behind modded engines. Simple. These shops are building them to the best of thier ability, and are willing to stand behind their product which is fantastic. Expect breakages. Or buy a C4.

turbotom Team Bute Donating Members 1,550 Member For: 21y 4m 4d Gender: Male Location: Adelaide Posted 09/11/06 06:19 AM Share Posted 09/11/06 06:19 AM Any of the trans builders can transform your 4sp ION auto into a much stronger box capable of handling some mods.The real issue is the way the engine is tuned.....Torque is the killer of these boxes.Engine tunes that provide lots of boost at low rpm have that fantastic push in the back sensation.... but the torque production is massive and that is what destroys the box. For reliability, have your tuner ramp up the power so that torque below 3500 rpm is limited to a safe level.My modded box copes well with around 220 rwkw at 3000 rpm (~700 Nm), but a race tune which delivered 260 rwkw @ 3000 rpm (~830 Nm) fried the band and scorched the drum. I've now reduced the power below 4000 rpm to flatten the torque curve.The issue with getting sufficient clamping force of the band onto the drum is the biggest limitation of these 4 sp boxes at present. Most of the other problem areas have been sorted out, but if wanting to pull some big numbers, the 2-4 band is where problems occur.I believe Kewish is working on a modified valve body to address this issue specifically. This is for mods where power is in excess of 400 rwkw!Give Dave a call to get an update.I think quite a few of us would like to get this problem sorted.When it is, there'll be many more 10 second T's on the street.tom Link to comment Share on other sites More sharing options...
