    I know these things are light, but using a plastic oil bottle as an axle stand is a bit extreme

    Looking good Dan

    What diff are you running? The usual Sierra one? I have a Cosworth Sierra unit in my Westie (3.69:1 or there abouts, I think) and I reckon it is a tad too short. It could definitely handle something longer.

    Are you still running stock boost?

    I find tiptoeing around town to keep the noise down and the tyres gripping gives me cramps in my calf muscles quite often - a good problem to have, but it is tiresome on occasions.

    I'm sure your car and Chris's Striker will be putting the frighteners lots of more expensive machinery.

    Regards

    How loud is that?!

    Quite a bonnet bulge

    I must measure up my spare CA... I wonder how much room I have to play with given the compressor outlet goes upward... although it is still bottom mount... hmmm, stuff to ponder.

    Hi Jamies

    It's 4.1 Quaife ATB diff so pretty sh1t hot

    Yeah I hear you about noise and controllability around town, it's bad enough on our driveway at work, especially as I'm running a RPS Max Street clutch which doesn't give a light pedal to say the least

    It's still running standard actuator at present but I'm happy with that as i can get used to it and then up the boost

    Hopefully should be able to MOT it this week/early next week

    It's probably slightly louder than a S14 with a single box system, but I didn't build it to be timid

    CA would be just as good in one, and maybe easier

    if you decide to change the diff ratio, id be interested in the 4.1. I have a quaife with a 3.9:1 built up to swap or a spare 3.62:1 ratio CWP or will part with cash, your choice.

    A 4.1 - and I thought my 3.65 was short!

    I have a Exedy Sports Organic clutch in mine and an S13 flywheel (S15 mill, S14 cogbox). Like yours, the pedal is heavy and the take up is rather severe.

    There's a GReddy Profec B Spec 2 EBC controlling my boost. It's an OK device, but really needs to be set up on a dyno unless you are prepared to tweak the settings yourself and monitor the digital readout while driving at WOT in third gear (as recommended).

    I have the EBC organised to give 10 psi on LO, and 14 psi on HI. I mostly get around on LO - it's quick enough and I have some concern for my head gasket at 1 bar (14psi) although most people I've talked to say it will be OK.

    There's also a stealthy Turbosmart Plumback BOV in the system.

    You wouldn't know my car is a turbo. The only slight giveaways are the three inch exhaust and the intercooler (which, to look at, could be the radiator). I don't have a boost gauge . The EBC head unit is velcro'ed to the scuttle . The stealth BOV limits the noise on change up to a satisfying ch-ch-ch-ch .



    How will you go for noise at MOT in the UK? Is there a dB regulation at a set rpm? A driveby test? Or do you just have a restrictor plate for the occasion?

    Regards

    Jamie

    Same with mine, the pick up is just amazing no lag just go although it's very noisy and when it pops it bangs like a gun

    over here the MOT is quite good on kit cars (Q plate ones) like mine, no noise tests, no emissions to really worry about. I don't think I even need to run a bonnet

    The main area where noise comes into play is for track use, for this I have a bung that I can place in the tailpipe to keep it down

    I drove it on the road the other day to the MOT station, and it's weird on the road. Things I've got to watch out for is when I shift down a gear the rear wheels lock slightly, this may be down to the diff design

    Also if the engine dies say if the revs full to quickly I can't bump start it in gear, again justs locks up the rear tyres

    Other than that it's fast and gave me a huge grin

    Looks like heel and tow will be the order of the day as the car is so light. Are you using a standard heavy flywheel?

    Hi Martin

    nah cyn-r-g aluminium flywheel I think that why it revs so well, the only belt it has is the alternator and water pump, so no strain of the power steering and also no heavy flywheel

    Ah ok, imagine how much easier it would lock the wheels up with a heavy flywheel

    I've been in a few muscle car's with original spec tyres and they can churp the back wheels just by letting off the throttle! (manual gearboxes)
