Supercharged K20a2 Vtec - Race Spec by cptkirk

3 minute(s) of a 377 minute read

Not a great deal to show you in this one, just adding shiny bits.

Charger is back on (with pulley properly aligned (3mm machined of the back face) and 5mm spacers on the alternator to give 4mm gap on the belt tensioner gauge), engine wiring loom is 90% there, just need to change the connectors to the injectors, they should arrive next week.

So here are a few shots of the engine bay:

Fuel Pressure Regulator

I whipped up a mount for the fuel pressure regulator yesterday, For those wanting to know its a Webcon and it has the insert that sets it at 3.5bar.

Not much more to say on it really - 'does what it says on the tin' kinda part.

Rear Diffuser

Started making the rear diffuser plug yesterday. I have to admit to the design being slighlty wet finger in the wind, however its not completely without research. Simon McBeaths Competion Car Aerodynamics book is a good read even if you cant do the maths behind it - I cant. It does however enlighten you you into the witchcraft that is aerodynamics. When starting out with a car that is shaped pretty much like a breezeblock with house brick on top you know its not got the lowest drag coefficient but anything you can do to try and make the car stick a little better to the road will help - especially when you've just put a 300bhp engine in the back.

Even a flat bottom over the engine bay is better than nothing at all.

So below are a few snaps of the plug for the mould being made, still a work in progress:
