It's actually quite surprising the box hasn't failed before when you think about it Jeff . You had their HD 250bhp max spec box and I have a Caterham Quaife box , but rebuilt to a higher spec by Brian when it was making funny noises 4 years ago ---- also to a 250bhp max ----- but only put 231bhp through it , as opposed to your 350bhp ish

On top of that , when my engine went from 200bhp on carbs to 231bhp TB's , I broke the halfshafts first time out at Curborough , so from then on the axle had quaife shafts along with the ATB already in there.
You still have the standard axle don't you

Just shows what the old English axle will take aye

Even though your 350bhp didn't bust the shafts , it'll now be the weak point after a higher spec box from Brian
H'mmm ---- ATLAS
