Really impressive F4R rolling road results from SRR

Thought I would copy this into a new thread in case people hadnt seen it in the RS2 discussion thread.

Modifications
Standard engine, MWM retimed standard cams, rs2, and an exhaust, MWM remapped.

Over 150blft for over 4000rpm
Peak torque of over 160lbft
Power of over 195bhp


I really cant see anyone topping that for a while in terms of such good N/A results with out needing multiple throttles or any engine internal work at all.

Anyone want some 421's? LoL

Cracking result, owner must be happy with that.

Is that a standard RS2 Chip or the "extended" version? Very similar to Nick172's results

That's a great result, pretty much gains everywhere over the extra length RS2 I had. Would love to see someone play with an extended version to see if there's further gains to be had.

I've always said the standard cams will clearly work better with timing work than the 197 cams after seeing the first set mapped. There's a guy in France making big numbers using GrpN timing on a standard length RS2/standard cams yet it seems no one took to the time to look into it.

Noos that was.


TBH when he first posted results similar to these I just assumed that it was a set of rollers over-reading.
I actually thought the same when I mapped Dan@SJMs 197 one as the rollers he used werent ones I knew and it made 200 until Mike did the same a week later on surrey rolling road with the same spec engine.

Mike and James havent been ignoring Noos though, in fact I know they talk to him a lot.



Mick, I believe this is a standard length one, Mike certainly didnt mention it not being anyway.

It's a cracking result either way and i'm glad to see the RS2 finally making good figures.

Who's car is it chip?

No idea mate. I only heard it about it secondhand from mike.
i was in disbelief when he was telling me how much fuel it needed when he was mapping it.

I said well it must have nearly 200bhp or a worn out fuel pressure regulator, and he said from how it went it must be the former!

It is indeed the standard length RS2 Inlet Manifold :)

Need to get mine back down to you soon mate, think I've done the 1500 miles running in now (hard to say as speedo is shafted lol) for map check, plus don't recall if Mike retimed the engine? want an entire front end refresh done, so that's something for you to look forward too ;)

Cracking results on the above car as well!

Grp N is also designed to optermise the engine on standard inlet not with the RS2 inlet.

I don't personally know what Mike has done to the timing but he's obviously spending a lot of time playing so I don't blame him for not putting the numbers out there.

I really need to get back down to see james and mike too, my rs2 made 187.5 at srr a few months ago but was advised it's running a bit rich.
I am also wanting a front end refresh I've had cooksports and spacers sat in my livingroom for months now.
Also got an annoying oil leak. Had the sump resealed but still losing oil and getting drops on my driveway, can't see where it's coming from though.

This sounds all too familiar scott.p mine is in the same situation.

I have almost a whole new front end to be fitted but don't want to do that until the leak (where ever it's coming from) is done so it doesn't knacker the new bushes... Will be on the phone to these guys in the coming months, no doubt.

These results look awesome, kudos to Mike + James.

If it's group N timing it's not rocket science.

Its sort of close to that. Mike has just been playing aroud with so many rs2 cars making tiny tiny adjustments that he's perfected it now. But group N would get you good results.
Utterly no chance he'll publish the exact value though when it guarentees he gets the best results in the country on these inlets.
Me and dan got within tenths of a bhp of him on 197 cams, and a few bhp away on standards, Paul at rs tuning has got within about half a dozen bhp on standard cams iirc, ktec can't even get it to work as well as a standard inlet. Flol, and I can't think of any other real competition mike has besides Paul and ktec.
So it's of too much commercial value for mike to publish the exact details.

True! If it's doing over 195 at SRR it would Probalby make 200+ elsewhere as Surrey is known to be stingy. Most standard 172s seem to make in the 160s there from what I have seen and modified ones generally only 170s.

That's a great power curve for a Clio! Would be well chuffed with that!

seems like with a little more revs it could touch 200bhp.

Lol! You've clearly never been to Surrey. If it runs well there, it will run well anywhere. Charlie is independent and his rollers are well known for accuracy.

A great result, well done chaps

As said stick it on some different rollers. :)

nope have not been to surrey before as there are plenty of rollers about that can give you a good reading. :rasp:

I'm not on a downer here (honest) as it's an impressive result, but you talk about this as if it's something that everyone is chasing? Are Ktec spending hours and hours chasing the ultimate cam timing on a car fitted with an RS2 (that let's face it is fairly rare in itself) - I doubt it. Would it effect their popularity if they did? I doubt it. Are they bothered, do they even care? I doubt it.

The RS2 is a product that only Mike and James sell (correct me if i'm wrong - I may be), so threads like these just strike me as one big advert. Add up the cost of it all (RS2 + cam timing + labour + mapping time) and I suspect there are other ways of achieving similar power figures.

Thats taking nothing away from the achievement at all, it's just my input on it all.

You can read how impartial I am elsewhere (and in this thread) but they one thing I will say is that i'd never doubt the SRR figures. I've had 5 different cars of all different makes on those rollers and I've had good and bad results.
