Excellent work.

What are the heads? The exhaust ports look like they could do with more work maybe??

Are you making up your own Supercharger fitting Kit or is it the SC Power Kit ?

the kit is an sc power kit, basically they produce it for the serpentine engine so i am using what i can i.e. mounting bracket plenum mods and intercooler but i have got to sort a driver pulley for the crank an adjuster for the blower drive belt plus the belt itself as unlike the serpentine engine it will only drive the blower and a power steering pump if one was fitted .

but i have been at it again today not on the engine as am awaiting supplies for the billet to turn up the crank pulley and some laser cutting for the bracket for the tensioner i have designed, but i have rebuilt the remaining rear hub now the seals have arrived,cleaned up the drive shafts and the cvj units, just need to paint those then they can go on,also made a start to the bad area of glassfibre around the offside manifold ,also got a pic of the finnished steering column with its power unit and sliding joint all connected, and i gunked and pressure washed the gearbox ready to paint the box itself.

been at it today got the nearside inner wing repair finished as far as the new glassfibre goes finished it with a cloth for strength and smoothness,also made a sandwich piece for the making good where i cut the old battery box out in the nearside wheel arch,got that jammed in place with some bits of timber then 8oz outside plus a cloth finish,glass the inside on thursday,fitted the refurbed driveshafts with new bolts and washers and got all the bits together for a machining day tomorrow,i have cut down the distributer to just a shaft to drive the oil pump and will make a stainless hat for it while on the lathe,so tomorrow big day turn up the crank pulley for the blower,billet of ally arrived today got the laser work back for d.c. development for the adjuster bracket for the blower belt,once these are done can marry up the engine and box and get it in the chassis.

Good work John. I have been waiting for this crank pulley and how it would all sit together. Looks like a top job.

I take it the blower mounting bracket is part of sc Power kit.

What is the idler / tensioner pulley from.

The trigger wheel is going at the back of the main pulley inbetween the timing case and the pulley the power steering pulley is there if one is fitted but with this set up should a pump be required you can use a serpentine pump mounted on the scpower bracket and a slightly longer belt. I am making the bracket for the trigger sensor tomorrow so will post pics etc. then

very nice, does that "green" wheel/tensioner also have a build in "damper" or belt adjuster shock?
when you speed up or down it could help?

say something like this without adjuster-shock?


BMW uses such sort for their serpentine belts.

No the tensioner is fixed and manually adjusted it dosent need to be shock absorbing as it only drives the blower which is a constant load with virtually no overrun as the components of the blower are very light unlike the serpentine arrangement or bmw stile setup where the alternator and other ancilliaries are being driven which have a considerable konetic energy stored when in overrun.
