I am building a 1310 road engine for the odd track day maybe.
Hepolite P21253 +40 Pistons
4.5 thou Deck Height
AC RS Cam
MED ST1 Lightened Flywheel and Performance Road Clutch Kit
AC 1.3 Rockers (Not yet purchased)
Metro Electronic Dizzy (to be re-curved) - will be swapped out for a non dizzy Megajolt or equivalent trigger wheel setup hopefully before recurving the Metro Dizzy
Now contemplating a Supercharger (subject of many other threads and posts on FB etc looking for info).
The idea is to finish building the engine up but ensure that when fitting the SC it will just be a head off and external modification, with all the internal parts sufficient for the additional torque.
Current build has a MED ST1 Clutch and Lightened Flywheel along with a 3.44 Single Molybendium Pin Diff (Built by John Guess), however for the increased Torque I have been advised change the Diff to a Cross Pin 3.1 and to look for an RTS clutch to be on the safe side.
1. Could I convert and use the ST1 and add another spring plate and swap the clutch disc for a spring one?
2. Thoughts on the 3.1 as opposed to the 3.44
MED have just messaged me and said the ST1 is good up to 70ft/lb, which is actually below the expected Tq of my non Forced Induction build anyway
