Project: RS2 ABY

[Sonic]

FFS just heard from Will the Southbend clutch fitted with the rebuilt is trashed already... going to be tough to get a replacement before the weekend when it's due to be mapped.

What is it with these effing cars?!

[Sonic]

Thanks JP - i was looking at the 034 RS2 alu but time constraints plus shipping hassle mean i've got for a billeted steel conversion to fit the DM clutch that Will got hold of.

It's lighter than the 034 one at 5.2kg but not 4kg light! It sounds like it might come down to a bit of tuning low-down to get it feeling right then.

Im going to stick with the RS2 box for now i think, but at some point in the future if it's proved to be a restriction i could look at swapping it for a cone filter with air vent inlet on the wing as pictured.

Flywheel wise if you want to keep your DM clutch as you are happy with it go for the RS2 SM Alu conversion from 034. I used this as an option on mine when I needed a quick resolution at one point. Weighs in at 8kg and felt really nice on the road with just the right rpm drop on gearchange without being so great it dropped out the boost band. Currently I'm running a 4kg alu flywheel with twin plate clutch and at first wouldn't drive nice kept having to rev really high to pull away and it would snatch and all sorts. However I've sat and played loads with the low down map for pulling away myself in what little spare time there is and I can now pull away as if I'm driving a normal clutch engaging at 1500rpm with no rpm drop.

Cold air feed is an absolute must and so is heatshielding. If ambient temp outside is 20celsius and I've gone for a run and park the car up just the heatsoak on the intake mani takes temps to 60+celsius. Will take a while for it to cool down to within 5degrees of ambient if not picking up some decent speed. So working on a nice ramair airbox round my filter soon.

Those pics of the wings look great, I am going to have to get new wings fitted at some point and get respray so may be tempted to do it at the same time

My mushroom air filter with the makeshift heatshield works nicely for me. It only gets too hot after a long drive and a standstill or the car parked. The combination of a big intercooler once you get driving again rarely goes anywhere above 8C- 10C from ambient when been left standing. On most occasions it's 5C more than ambient and if the water meth comes in it drops fast

The filter sits in a very hot location, right next to the manifold and turbo, so a shield for a cone filter must be close to airtight, as the engine will suck hot air through any opening.
The RS2 airbox even has a heat shield on the outside of the sealed airbox, and I don't think Porsche did that for fun. (not sure if the ABY, etc. box has that sheld).
(Edit: I see now that the ABY box has a heat shield over the lower part of the box, while the RS2 box has a shield over the upper part as well)

Easy to test various setups by logging IAT (in similar ambient conditions) with Vagcom (even the £5 cables will do this)

Doesn't look half bad... something for ish to consider.

Or how I did mine. Completely shielded with a 3" pipe/air scoop that passes through the inner wing to get cold air..

[AndyP]

This is what I'm hoping mine will look like

The only way to properly do a cone is with the MTM style airbox.

[Ross]

Well my BMW foam filter was still in one piece last time I risked losing fingers opening the airbox... 10k miles no issues. I'll check + clean it whilst she's off the road now.

Id echo the cone filter comments. I tried one years ago before I had the RS2 box and there was a noticeable difference.

If anything look at how you could increase airflow. maybe inlet through front wing with the louvre panels

Like this maybe http://www.venommotorsport.com/produ...ry=Bodystyling

I'm going to use one of those from a T4 van in my front wing. I'll post some pics up when I fit it.

If you make a decent heatsheild there is no reason the air from a cone filter will be any hotter than with an airbox.

[Sonic]

Oh god, not sure i could cut the wings out to install vents... maybe let Ish consider that when i finally let him have the car for painting / bodywork

Ross, how does the BMC foam filter compare to the pipercross filter? Mine managed to destroy one very quickly hence why i went back to a K&N filter.
