That graph and the one posted by dr jekyl above it show why people should take to little notice of a peak torque figure, LOL
J's is 151, dr Jekyls is 155
But J's holds peak torque for the entire rev range, dr jekyls just spikes to it briefly. so dr jekyls has a few lbft more for just a few hundred rpm but at other places like at 3K, J's absolutely trounces it.

Chip, a better graph pic is needed! Lol
Yeah, thats only rolling road day Ive been to and the rollers couldnt cope with it grip wise hence the lack of full throttle
Its been on the rollers for mapping as well, but when Im mapping it I just look at the screen and never bother with printouts, will have to get one at some point though.
We did get one when me and Mike mapped it originally from Surrey as a demo of what it did, but that was much lower figures.
Copy of it from the first ever post I made on CS (I only signed up to post the graph for Mike as he was having internet problems at the time, now I practically live here, lol)
I take it all your graphs are ATF power?
The RR days i've been on only gave you power ATW graphs.

I like your nail varnish Chip.

After having an RS2 fitted I think it just detracts from the way the car should be which is 'peaky'
I felt it just stole peak torque to give it to lower in the rev range, I couldn't see it's uses as these things are in the power band when in use, for e.g I would rather have dr jekyl's graph than tim's as I find it a more useable power for my uses.

Looks like MWM is in need of a visit !
Standard inlet dies on its arse at 6500 and makes you have to change gear mid bend sometimes as a result of the peaky delivery IME, the gearbox isnt close enough to keep it on the boil.
Thanks. I only wear it at weekends. I dress straight during the week for work.
Thats I lie, you looked stunning at the Ace cafe meet.
RS2 tails off too @ 6500rpm but from a lower peak torque. I just think the higher torque figure in the area that is used when on the boil is more beneficial with the standard inlet.... especially with supporting mods. In general the standard inlet has the RS2 on level pegging and beaten above 4k, my car just felt broken (flat) when I had it on.
My opinion is based on use on track, no denying they look tarty though which is what drew me in initially.
Look at J's graph mate,
Power is still climbing after 6500, and torque at 7000rpm although dropped slightly is still 145, versus more like 125 on the standard inlet (as you can see from his before and from the graph above from dr jekyl) and if both graphs went further up the rev range you would find it even more noticeable at 7500 than it is at 7000, by then the standard inlet is down to about 100lbft and the rs2 still over 130.
Its for track use that I like the big difference at the top end of the RS2, on the road i dont tend to rev it over 7K anyway, but on track I do. And on these engines an extra 20lbft at the top of the rev range is not to be sniffed at IME.
With the 197 cams as well it shifts it even further, they make peak power right up at about 7800 by then, which really allows you to exploit the mechanical advantage of being in a gear lower for a lot longer.
Maybe yours wasnt very well mapped or something like that?
No idea why I can't make it bigger than this.

Attempt at resizing for you.
How much of that is RS2 and how much is the supporting mods in that example. No mine was never mapped I just let it self learn over a while (not ideal) but it got better from a running point of view every time I had it out initially.
I just found it of no benefit on a lap round KH over my standard car where as cammed cars had the edge on me.

No wonder it didnt drive right! As it will NEVER self learn to add in a load of extra fuel at high rpm. So you wouldnt have been getting anything like the benefits that you would if it was mapped.
What you did was the equivalent in mapping terms of if I fitted some AST and then didnt get my tracking or camber setup and then said they were rubbish!
Easiest way, open it, press "ctrl-printscreen" then open up mspaint and do "ctrl-v" and save it as a jpg.
I did say it wasn't ideal in my post although mapping it wasn't going to make a night and day difference imo, you could feel it going lean and the engine note change but only for circa 500rpm. I realised for the spend it was pointless for my use and sacked it off.
Most people seem happy with them for their use which is fair enough although guys who have raced and tracked them tend to agree with me, including you
It really does, bare in mind Ive mapped a few of these now, so am not guessing like you!
It will be losing out before you really feel it, you just felt it once it was so lean it was really losing power, but it will have lost out sooner than that too.
Shame you dont still have it or i would have mapped it for you and shown you what i meant.
I dont know ANYONE who has had one mapped properly and then says that on track they would sooner have a standard manifold!Most people seem happy with them for their use which is fair enough although guys who have raced and tracked them tend to agree with me, including you
In fact me and the mrs were both bitching like mad at the new 182 at llandow at how rubbish it was there engine wise compared to the RS2 car we did it in the time before and the only difference between them is the engine spec cause we put all the suspension and brakes on the new car anyway, so where as before with the RS2 I was easily a match for the williams trophy on track (much lighter than ours as theirs is stripped where as ours is a daily) now they were walking away from me, it really does make that much difference, and thats direct back to back comparison against a car im reguarly up against.
Mapping on my rs2 made night and day difference IME. Felt hideous before hand.
Agreed, beforehand at the top of the rev range it just felt horrific, I bet it was no more than 170bhp and after I mapped it, it then made 200bhp, if thats not "night and day" on an N/A engine then I have no idea what swede cup thinks is!

Yozza manifold back exhaust
Charlie seemed a little disappointed when I took it down to SRR for a rolling road day as it was running a touch rich, he thinks it should be low to mid 190's, Something for Mike to take a look at when I get my suspension refresh sorted.
I know of one car that run one for a long period without mapping and needed very little changes at rs tuning when it was mapped.
I'll bow to both your's experience with them, I just wasn't massively impressed with it plus no one has got over circa 150lbft with them. Seem's like an end of line mod to me with no where else to go where as 2nd hand itb's will have infinitely more tunability for the same spend......and be easily returned to standard by the biggest spanner phoebe which is the biggest decision maker on CS for the RS2.

Well mine needed quite a bit of work to the map as the first run had to be aborted as it started running way too lean....
It also ran like s**t before it was mapped.

Was you not the guy that bought mine?
Nope mine was new from James/Mike
Wrong spy, out of interest how long did you have it fitted before mapping and did you kick it's head in? Mine was also rubbish to begin with, I posted a few threads on here but after resetting the ecu and allowing it to self learn it improved. It can't learn enough from what chip has said but other's have had different experience with them,
