As a few of you know we've ran the 197/200 chassis in various forms of motorsport since it was released. We've supported Clio Cup teams, built X85's and road cars into everything from front running/giant killing 24hr endurance cars to driving experience cars and developed a range of components for them when what we needed to win simply wasn't available off the shelf. We've lightened them, dry sumped them, tweaked them and even done a full paddle shift and hand clutch one ala Megane Trophy.

So if you have a question about anything related to the 197/200/X85 in motorsport ask it here and I'll do my best to give you a detailed answer.

What's the suspension setup used on a X85?

Specific bilstein dampers with eibach springs front and rear. Both ends on spherical bearings with the fronts adjustable for camber and the rear top mounts picked up into the roll cage. In 2008/9 there was an update to include spherical bearing front wishbones which removed the last bit of rubber in the suspension and much improved initial turn in. The rear beam was on spherical bearings from launch.
 
Is there any worth to fitting an oil cooler (mostly road use but 4/5 trackdays per year, but this will be increasing over the next few years)? Also, there's one or two people talking about oil catch tanks recently and I've had one before on a car (fitted when purchased) but I was wondering if you think it's actually a worthwhile thing on an F4R or not? I know what they do, basically, but do you think they're actually worthwhile?

Last one... Is the 197/200 sump baffled as standard? I've read somewhere that it is but I've never had mine off to check. If it isn't, have you ever had any reason to modify one or had any instances of engines suffering with oil starvation in race conditions?

I'm sure I'll think of more questions!!! :smiley:

Cheers,

Will

Standard road car and X85 runs a modine type oil/water heat exchanger. This is fine for short durations and only really puts a load on the cooling system that's not acceptable in serious use in high ambients with modified engines. However air/oil coolers are easily fitted (we do a kit) and are in use on most of our race cars and some of our highly modified road/track cars.

Oil catch tanks make good sense to avoid recirculating the engine breather into the inlet which can cause oil fouling of throttle bodies as well as lower the effective octane rating of the fuel (if the engine is breathing heavily). It's worth having one just to monitor how much the engine is breathing as it's a cheap and simple mod.

The stock sump is not baffled but has a good windage tray design and is fine to short period 1G lateral. It is not suitable for sustained high cornering G such as Mallory or similar.
 
Cracking info', thanks!!! :smile:

There's an oil cooler on the shopping list and I wasn't sure about the catch tank but I think you've made my mind up for what they cost. Anything that helps the engine or helps keep an eye on things is worth having in my book. Out of interest, what's the cost of your oil cooler kit please? Also, do you have any plans to market a baffled sump or is there an off-the-shelf item already available?
 
Most of our really serious race cars run dry sumps. The stock sump is fine for slicks use on everything but very long corners i.e. Mallory and a smattering of European circuits. Don't worry about it - if we do a baffle kit it will be because the race cars need it and we'll make it available to road car but unless you're on slicks it's not something you need worry about.

Our OC kit is £299 + VAT for the thermostatic version and includes everything required, oil cooler matrix location is up to you as we supply plenty of pipe :wink:
 
What sized oil cooler would you recomend?

They used to say a 13 row cooler was enough for a 2.0 car but with engines growing hp wise do we need to go bigger?

Does the X85 use the same hubs/suspension lower mounts, ie would the bilstiens fit onto a road car, lower mounting wise?

13 Row is an entirely sensible size to start with. The end size of the cooler will be determined by position on the car, ambient air flow into the duct, heat rejection into the oil etc. etc. You can never had too big an oil cooler as with a thermostatic plate (or duct tape) you have control over how much it cools.

Unless the road car is a dedicated track only car it's not worth considering this option. The lowers will go on, there are some differences in the front suspension though, not just top mounts.
 
was it complete new ohlins shocks in the x85 car or just inserts


We have run Ohlins on a number of X85 and R3 cars.
 
matt what size oil catch tank would you recommend for the 197/200 for fast road plus occasional track days?

Complete replacement.

another quick one matt, whats the black plastic diaphram looking component inline with the breather pipe connected to the plenum
