Supercharged K20a2 Vtec - Race Spec by cptkirk

3 minute(s) of a 377 minute read

As you can see in the below picture I am running 2 calipers, the Sierra type and the Wilwood. I am using the Sierra with a cable for the MOT handbrake and am going to be connecting up the hydraulic of the same caliper to a fly-off hand brake (for hill starts, not getting sideways - honest.....OK its all lies).....Even after all these years of ownership I haven't got around to fitting the fly off, I only need a couple of parts and I could do it, just another 5 min job, right.!!....

Re inner arches I made the molds and a buddy did the fibre-glassing for me.

I am based just outside Chichester, West Sussex, not far from Goodwood, if you're in the area give me a shout.

Avon ZZS 245/50 R13

I eventually got around to getting them fitted and thank god they work under the arches. I took off the 5mm spacer I was using but to be fair it could've stayed on as there's room for it. Fortunately I didn't have to monkey around with the wheel studs, however be aware if you're going really deep into the wheel nuts you can suffer from bad threads and pick up as recently happened to me......

Supercharger Snout Brace/Clamp

Quite some time back, when I put the chargecooler on, I made a snout brace for the supercharger.

My thinking behind it was to:

a) relieve stress from the intake manifold to cylinder head bolts,

b) to replace the original idler pulley position to greatly improve the effectiveness of the belt tensioner (JRSC setup without idler was rubbish)

c) adding a further idler pulley would greatly improve the amount of belt wrap on the charger pulley as it was getting spun faster I didn't want belt slip.

I mistakenly thought that a slight interference fit would suffice to keep everything in check, nope...... I cant begin to explain the amount of black cr4p produced by the two parts rubbing. So below we see it as was (1st picture) and then how it is now after a cheeky bit of machining by my good mate Stevie G....

That bad boy is not going anywhere now it's clamped down properly...
