    We will go semi*-spaceframed when Dave stuffs the front end into the tyres

    Note.. semi- spaceframed, original chassis rails will remain. And the rear suspension pickups will not be directly mounted to the cage/frame

    I like rules

    basically we are making a pre-emptive strike to stop something like that being built, its getting harder all the time to rewrite the regs around cars already competing, and in any case its a saloon car championship we dont want it full of jelly moulds, other wise understandably the normal tin top drivers will start complaining.

    ..............start complaining????!!!!!...........

    Makes sense Graham TBH I'm suprised that 'jelly mould' spaceframes are allowed full stop, they never started as a saloon car merely a bathtub and some scaffolding
    All cars should have to prove they once had 4 seats
    Mind you theres the trigger's broom arguement and they can just say they the changed the chassis... and then the changed the bodywork, but there was a std car there at the beginning.... once

    Got a nice bag of goodies for the car the other day including this beautiful intercooler and loads of samcos off of a mate whos breaking a twin turbo sierra xr4x4;



    We cut out the origional radiator surround to get the intercooler sat in and after a bit of a play with the pipes its all plumbed in bar the second dump valve t-piece and an adapter to do on the throttle body

    We cut out the air intake that was used on the zetec install and I tidied up the front panel. Just need to make some ally blanking plates to go either side of the cooler





    Oh and finally couldn't resist making a few extra holes just to give as much airflow to the cooler as possible



    All in all not a bad days work methinks Cheers to the Andy and Alex for their assistance

    No Mark, I think you've been on the beer again

    Cheers though guys, Intercooler looks good, just need to get a rad to fit perfectly in the gap now and we're laughing. Maybe 3 of Richard's Polo ones will do it

    If you want both inlet and outlet on the same side of the car then a mk4 golf gti rad is pretty much full engine bay width for about £50

    Dave did you use one of those special offset rulers when you were marking out the holes in that upright

    What I'm after Rich is as thick (Core) a rad as I can find but it only needs to be about 500mm wide and 450mm tall as either side of the intercooler will be blocked of to stop the air trying to bypass it.

    The outlets are on the diagonals but opposite to the normal escort setup Any thoughts?

    Did a couple more bits today.
    Fitted the intercooler mounts to the anti-dive kit and tidied up the remaining metal on the inside of the front panel ready for the ally panels to go in either side of the cooler.

    Painted in a few of the black bits that had been cut and straightened out the holes in the front panel a little for Jon

    If that rad doesn't fit Dave, try here http://www.radiatorsonline.co.uk/buy-car-radiators.php. I prefer to try and make standard oem bits fit as they are much cheaper and easier to replace

    Know what you mean Rich, origional parts are a good way to go but when the lovely one off ally stuff comes up at the right price you cant say no

    Just have to be careful not to bump the front too hard

    Right, thanks to Jezz I now have a lovely alloy rad. Picked it up today so I thought I'd give it a quick mock up and it fits like a dream

    Here's how well it fits;









    Even trial fitted a bit of my old rad top hose with the temp sender in it and that goes on easy, so now I can get the same but in samco made up

    Made up the inlets for the throttle body today

    Not bad really considering it only cost me £13.50 and a pint of scrumpy (£13.50 for the 2 90 deg bends and the scrumpy for Gary to weld the pipes to the back plate I'd made )

    I also spent a while porting the throttle body into the pipes to give a nice smooth flow.

    Just need to smooth the welds a bit and give it all a coat of silver paint and job jobbed;





    Will point the dump valves down now to give more room, just wanted them on show for a bit first

    rich is right , do you know what ecu your going to run yet dave, emeralds latest has a brilliant closed loop egt (exhaust gas temp) facility which can richen the mixture or back the boost off if the exhaust temp starts going to high, and exhaust temp is critcal on turbo motors

    Another vote for Emerald here, mine was bloody brilliant (doing a good job controlling my bedroom from the top of the wardrobe now ), and the manual with wiring diagrams made it very easy to get working.

    Re: David White's - Mk2 Escort - Cosworth V6 Turbo

    Karl at emerald is busy adding new features all the time, they can now have switchable maps, ideal for a race car so you can have a wet, dry, and oh my god qualifying maps that you can switch between on the move.

    another good feature for a race car is the facility to run different boost levels in different gears.

    they have also done full throttle gear shifts, although probably a waste of time on serious horsepower cars as mine will break traction every gearchange all the way up the box anyway, and i feel full throttle shifting is probably harder on the transmission.

    if you have the appropriate wide band lambda probe, as far as fueling goes the ecu can map itself, although i'd rather have dave do it anyway

    Am probably going to fit either emerald or DTA Pro 8. The only thing in the favour of DTA is that Steve G is very familiar with it and he is a lot more local than Mr Walker.
    The DTA has sequential injection, traction control*, anti- lag, full throttle shifting etc aswell so I think it covers all my needs. Not sure if it has switchable maps though, need to check as that could be very handy like you say

    * yes I know its illegal so that wont be used, much

    very nice Dave

    I was considering DTA on an old car of mine and i have to say it looked good... but i sold the car so never got it on there in the end.
    Will you be running anti-lag on your engine? If so, I hope the turbos are the proper maram shaft ones or they probably won't last too long!

    If you can run closed loop, I definitely would! As Graham says.. very handy thing to have!

    sequential injection wont gain you any power, in fact it might be a disadvange as it will mean you need bigger injectors,

    traction control would be nice but its against the rules

    i suspect your car will be like mine, want full throttle gear shifts like it needs a hole in the piston.

    whatever ecu you use you really want the ecu to control the boost presure, that way you can have a nice predicable power delivery, that will back the boost off on the smaller throttle positions for greater control.

    the emerald also has anti lag software, although on a tarmac race car i dont feel it important like in a rally car, avoiding lag is a much about correct gearing and driving technique as anything

    I wouldn't use T/C anyway graham, apart from the fact that its cheating and easily spotted (sensors on each hub?) it also would make things even more complicated to wire and map and keeping things simple is the most important thing right now!
    Anti-lag also is more suited to other applications and can be very bad for the health of everything under the bonnet.

    If we don't use sequential injection wont it just dump the same fuel down all 6 pots all the time? Surely this will use a load more fuel and mean there is unburnt petrol on the pistons that aren't firing? Or am I understanding the whole thing wrong ???

    going sequential injection only benifits in terms of exhaust emissions, not power, you end up with the same amount of fuel in the engine, just if you run sequentially you may need bigger injectors as you have fewer injection pulses so the injectors will have to flow more fuel, plus the added complication you will have to run a cam sensor so the ecu nows which phase the engine is in, sometimes non sequential will give a bit more power as the fuel will cool the backs of the inlet valves more and thus they wont heat up the incoming charge as much.

    i know what you are saying about non sequential throwing fuel in, but it doesnt work like that if it did a carburettor engine would never work properly

    personally i think its a good thing on a cat equiped emission consous road car, but waste of time on a race car

    Cheers Graham I'm learning all the time about these things and I just want to get a decent set up on the car from the beginning so that theres moe racing and less tinkering / repairing later on.

    Any ideas which model of emerald ecu it would be for mine?
