all you need do is swap battery, wires on ammeter and reflash dynamo, no need to bugger around with control box, just flash field terminal to battery positve

If the starter has a weak bendix spring it will get thrown out the moment to engine even thinks about firing

just use a hammer and punch, a swift blow close near one edge tips the core plug sideways, and pull it out with pliers. i have removed 100's like that never damaged a block

it would of been postive when new, but impossible to say now, in my experience most cars have been converted to negative earth

ive started a new video seris a strip and rebuild on an s1 2000tf

ive seen red plugs from engines on teh dyno, usually from an engine burning a bit of oil

my daily driver is 3.0 turbo diesel and has 300 bhp and 480lbft, i really cant use all of the on the road but it makes a very nicer drive

i can only say what i found, but on my engine dyno i had a little over 290lbft and the clutch SD1 couldnt cope

4.6 is ideal for that, as i said ive only ever driven a 4.6 p6 as a manual, but having driven the same car as a 173bhp 3.5 then as a 4.6 using same heads cam etc, the 4.6 was just so much nicer, you could just squeeze the accelerator when doing 25 ish mph and it would just pick up and go as if...

i think how well the diff holds up will largely be down to driving style. my only experience of using a 4.6 is a P6 is that a perfectly good standard 3.5 clutch couldnt cope with the torque and would slip even with fairly gentle throttle applications

my only concern would be if the gearbox can cope with the torque. Even on SU's you it will/should generate around 300lbft

so far i have only dyno tested one totally standard P6 engine, from the power that made i dont think SD1 heads are a big leap, certainly not on a standard engine. Standard p6 exhaust manifolds look awful but for mildly tuned road cars i dont think they are that bad, as proof i would say look...

following on from comments in my recent air filter test i pulled together a quick video of tow very similar 3.5 v8's and look at the power difference between one with stock 3.5 heads and one using mildly ported 4.6 heads

when you consider the internal area of the elbows is probably 4 times that of the carbs themselves so finish inside the elbow is going to be pretty meaningless

i cant see polishing the inside of the elbows would do anything except take up your time!
