666 is almost there, just Cosworth cams, clearances and the final build
666 has now got a sister and they are in love WR1 vs P1 2.5-3.0 bar if they can so no pressure then JDM starter heads Dye crack testing Roughed up ports Anti pre-ignition curvy corners 14mm studs to keep it in Supertech valves to get it out Finished specimens No porting please Just needing to fit these bad boys after they are de-burred polished Found Rocko's new boost gauge as well Advanced Automotives.com

I cant wait for EngineSpecialists to finish your engine Rocko, that way he will have the skills needed and have secured adequate supplier discount deals to be able to offer me a bullett proof engine for my 2k budget ol
Not quite sure if this is applicable to the specific reasoning behind this build or not, but I think it is something to do with keeping the fuel atoms suspended in the air mixture. An old motorcycle racing friend of mine who worked for BAE did some research into this many years ago and went from perfectly polished to slightly roughed up. If the port walls are perfectly polished then you will get a far smoother air flow, however the mixture has a tendancy to seperate in the boundary layer and fuel sticks (for want of a better word) to the side, making the overall mixture lean. The tiny surface imperfections disrupt the boundary layer and prevent a pure laminar flow keeping the fuel nicely suspended for combustion.
Er, yeah, that's what I thought!
Fair play Caveman .. I knew some one would hit the nail on the head .. Nick from advanced Told me about this in the week as i asked the same question ... All rough'd up Just like the Birds around my end ... but PASTY loves Em "666"

Caveman has it in one Keeping the fuel in the airstream so it does not seperate and cause areas of weak/rich mixture, can allow a better burn and more ignition timing before detonation becomes a problem. The nett result also means that the fuel burn speed is more stable and therefore the cylinder bmep is higher so more power for longer. The problem with high boost is that the flame travel speed will slow down (more too burn) so so we need to keep things nicely mixed up. Don't know if your birds are like this as well Rocko Advanced Automotives.com

I think this needs a mention. Castle Combe had a track day (open pitlane) on Tuesday that was organised by Apex Track Trackdays. I asked Rocko if he would be interested in coming down for the day to show off his WR1. He said if work permits then he would, what a gent.
He found the time to come cross country and did as he said but not only that, he also took a number of people (they were queuing up for it) for a couple of laps around the track including myself. We all agreed that his WR1 has incredible performance but also just as impressive was the handling and the way it just stuck to the track. A real super car for the road and he can drive it too. Anyway, I want to say a massive thanks to Chris for taking the time to do this and below are a few pics that one of the BBS members took. He too seemed to love it as well. The new 666 improved version is going to be on another planet Advanced Automotives.com

hi nick, what's the cam duration on those cosworth cams?
i'm lookin for some cams to fit 2.5 avcs heads(hawkeye), need to be really wild to pump enough air with a gt42-35. i've already got the oversize cosworth valves. any ideas? thanks adam Buxton Subaru Centre. 01298 27391
Well worth 222 mile round trip to Blow the Cobwebs out off her ...
And she never missed a beat thanks to Nick.." Legend" For Building my 2.1 stoker .. Ill miss her .. Or Will I lol My favorite corner of the day is Folly as its Flat out 5th .. And Old Paddock Bend as its a Mint coner if you get it right out of the esses Thanks for the Invite .. "666"
Well done Rocko !
I guess that if you weren't before, you are NOW a member of BBS ! My WR1 has its history down there with it's previous owner. Yours takes the mantle !
Hi Adam, hope things are good. Kelford do a wild cam for this and I had some good feedback from a customer apart from a stupidly bad idle problem because of the low manifold vacuum, this also led to fouled plugs on occasions. They have an 11.55mm inlet valve lift but do have a slappy flank which will be noisey on the valve clearance. The spec is below:- Advanced Automotives.com
Subaru Engine Specialists
She will have plenty of cobwebs and dust soon and I will organise for you to clean your own car so you don't feel left out...again You could go back up Combe after and see if Folly still works flat in 5th. Left side of the car says it wont. lol Advanced Automotives.com

I will be at Rally day on the Bath and Bristol Scooby stand but not sure if we can get Rocko finished in time for an appearance. Rally Day is an awesome day if the weather is good Advanced Automotives.com
