Hi Guys,
One of my mini's has a MK3 'S' engine fitted, the basic spec is as follows.
1293 cc
GTS Box, 3.44 diff ratio, on 12" rims
10.2 CR ratio
MK3 12G940 head
Standard Cam
Maniflow Exhaust Manifold
RC40 twin box 1" 7/8 bore
Twin HS2, red springs, 'M' needle, chamfered piston, reduced butterfly spindle and butterfly
Reworked BMC 12G264 inlet manifold
Accuspark Ignition in a 45D4.
So I'm going to say it should be about 80bhp at the flywheel...ish!
I'm toying with the idea of switching to 'AH2' needles or switching to Twin HS4's and re-working them also?
Question
Can you recommend a needle change to stick with the HS2's? Or a switch to Twin HS4's and a needle and spring change also?
Cheers!!
