Mini Mania can supply you with a ready to race straight cut close ratio gearbox! Quality guaranteed! Our race gearbox is built to exacting standards with all the tricks learned over many years of development. Our boxes, either stock or race are guaranteed to not to pop out of second gear! The stock ribcase gearbox of any AH Sprite and/or MG Midget can be transformed into a superb racing box with the installation of straight cut gears! Not only does the straight cut design provide more strength and take significantly less power to drive but the ratios of the various gears are ideal for high performance racing! Yes, the nature of straight cut gears is that they are louder than the stock helical, but if you are racing you don't care about noise, only performance. This gearbox when installed will make a 948cc engine feel almost like a 1275, and a 1275 will feel like a 1500! You can always be on the proper power band of any motor! The RPM drop as you upshift is dramacticaly lower and thus momentum is not lost and your screaming motor will be allowed to stay screaming! Ratio <P>Comparison: Stock S/C Close ratio <BR>1st- 3.2 vs 2.573<BR> 2nd 1.916 vs 1.722 <BR>3rd 1.357 vs 1.255 <BR>4th 1.0 vs 1.0
Question:
If I send you my rib case transmission for my 1275 Austin Healey motor can you convert it to strait cut close gears? It currently has the helical gears.
Answer:
Rebuilding ribcase transmissions is a "parts + labor" cost. It's difficult to say and will depend on what parts are needed and how many hours are spent. We do offer a complete rebuilt straight-cut gearbox on the site as part number C-AJJ3319-C and it's safe to assume rebuilding it could be up to that price (without having it here to inspect, no way to know with certainty)
These gearboxes are built to order, and may take 4-6 weeks.
