Well, the time has come where I thought I’d start a new thread for the rebuild, as it’ll essentially be a fresh start for the car. The plan is to start work on it now so that we don’t have to rush and can take our time to think everything through properly. This will also help with the cash flow situation!! We’ll work on it throughout the winter months and well into next year, ready to hopefully do lots of late Summer/Autumn testing so we can hit the ground running for the 2015 Time Attack Championship.
So, for this rebuild I’m probably going to be leaving the bodywork alone and do that side of things properly at a different time with lightweight clams etc. Essentially though, I’m going to re-do everything else I can and have a proper tidy up.
There’ll be a whole load of new parts etc going into this build, however the main things that we’ll be doing are:-
Syvecs S6 ECU (with individual cylinder closed loop knock control)
New front loom, to replace everything that got damaged in the fire and lots of extra sensors throughout the car in order to make full use of the new ECU.
Bespoke M&W Pro 14 sequential CDI ignition system. This is probably the best capacitive discharge system available and should easily eradicate the problems we were having on track once things got hot and on high boost with our standard inductive coil packs. We’ll be working with a US company who are developing a package especially for the Honda K20.
Final spec still undecided, however almost identical to the previous engine, but with beefier pistons & gudgeon pins and slightly lower compression.
Twin Bosch 044 pumps. Large capacity billet fuel rail, fed from either end with central return feeding into a Bosch Motorsport boost referenced adjustable fuel pressure regulator. Also some much larger Injector Dynamics 2000ID 2225cc injectors. Possibly a fuel cooler too, but we’ll see if we would benefit from one first.
Bespoke Dry Sump system which will run off the oem chain system and all fit inside a normal size sump pan.
Bespoke removable tubular from spaceframe to replace the oem crash structure. This will allow me to position the engine radiator and big chargecooler pre-rad a lot better, making our cooling package much more efficient. It’ll also allow me to vent all the hot air from the pre-rad into the wheel wells and not the underfloor as it does now. It’ll also allow me to up the game in terms of front end downforce.
A few minor rear end tweeks, new slightly different diffuser, undertray, running boards. New front splitter design incorporating venturis which will vent into the wheel wells giving a huge improvement to front end downforce. I’m also going to be cutting away and re-sculpting a lot of the sill section from just behind the front wheels, going right back to the chassis and then back out to the sill again with a nice smooth transition. With a bit of luck this will allow all the extra air I’ll be pumping into the wheel wells to escape efficiently.
Well those are the main bits anyway and you’ve probably got the gist, but I’m sure I’ll come up with some other bits and pieces too.
So far, I’ve only spent a couple of evenings on the car, but I’m basically down to a bare tub now. The next job is to get the front crash structure off so I can start the spaceframe. I’m really, really not looking forward to this particular job, but have been given a few pointers by Junks on the best way to attack it. I’ll get some pictures up as and when I can.
Wish me luck…
