Rs2 inlet
- Thread starter newb
- Start date
Apart from that Russian guy who made epic figures with forged setup, I've never been that impressed by any of these cam 'choices' for the RS2...
Standard cams with 50mm spacers on standard timing, I'm almost certain that with playing with the timing you could make some better figures, without spending a fortune on camshafts that loose you torque.

I'm going to need your car keys when I get back Mick. Or maybe I'll donate some cash towards a passenger seat.
IME Surrey is consitantly 5-10bhp higher than RST. They both seem consistant in their results which is what matters I guess.

That's not too shabby at all.
No wonder it shifts so well.Lol what?
Mine was within a horsepower between the two places, RST result being in the summer, SRR in the winter.

For the first time (in a long time) I'm actually happy with the car. It's always been run and mapped by Paul so the gains are consistent. Just from driving it you can feel the car has totally changed character on this inlet which for me is a small triumph as a lot of people hate it.
I am not dismissing or hating on the Surrey/Standard Cam chart Nick but my setup on standard cams also pushed 195.3HP (Historically on TDF's rollers) yet on Pauls it struggled to do 186HP so something amis there. Tweeking the timing is just such a pain in the arse, not to mention costly in travel and remapping, the camshaft upgrade was just an easy way to add some actual improvement in the the midrange and peak values. They came as part payment on a job to so not really a huge expense. I would just like to see what it would do elsewhere.
Blyton next Sunday will be fun though I suspect.

So you're saying your car made 195bhp on TDF's rollers (which are a different set of rollers to RST/SRR and well known to throw out some bullshit figures given what all the Clio racecars have made), and you think that's a reflection of what SRR's roller would show?
For reference my standard length RS2 made 191bhp / 151lb/ft at RST on one of the hottest days of the year, which says to me that if the engines good/timings right then you'll make good figures.
There's no doubting it was a cheap upgrade for yourself, however I think for a full paying customer its a lot of money to shell out for not a lot of gain.
But if you're happy with the difference it's made Mick then that's the main thing, however it's probably the lack of torque pre 4k and then the rise in torque from the (laughable) 197 cams torque that's made you feel like its much quicker.

Comperssion test will tell you if its internally in bad condition or not, but Ive yet to find anyone who can identify why certain examples make a good few bhp more than others, even when both compression test fine and both have had cam timing checked etc, it must be down to production tolerances somewhere I guess, millerins cup for example, nothing seemingly special about it, but made 182bhp and 165bhp at SRR, which is just monster for a standard car with exhaust / filter / JMS map
330i. E30 Touring.
Put it alongside another known strong car is the only way really. It's entirely hit and miss otherwise.
I'd like to take one of the "strong" ones and strip it right down and measure every single component to find a reason, but the odds of someone handing over a car thats working perfectly to be pulled apart is pretty slim.
And realistically you would need to do a few before you started drawing conclusions.

Its only when you have two side by side you notice it really as although 175bhp or 182bhp sounds a big difference, its actually feck all in terms of how they feel to drive if you drive one after the other.
I reckon @MicKPM would be up for it
Micks never made monster power as standard though, so pulling his apart wouldnt show us anything.

If you're serious Chip i'd let you have a go as the ITB build is going to be pulled down and the crank/rods sent for full dynamic balancing. It deffo won't be something I want to do just yet though as I plan to just enjoy it next year. Telling the missus i want to spend another £3k on "That s**tty car" is an area I may not go into negociations with her on until the new year (2015)
I have my old B/E here and sat on the floor now though which you can have providing I get it back

As I said mate, yours is no use, it would need to be a car that is currently standard and making numbers well over the odds, and would need a couple of them to contrast and compare.
Sadly with no budget, its unlikely to happen as I cant see many people saying "my engine is awesome and working great, i will take it out and put it to one side ready to be pulled apart with some others"
Shame though cause it would be really interesting to know.

I wouldn't mind having a go with a RS2 inlet on mine.
I've got the Piper cams with headwork and 182 manifold. It makes 184bhp and 173lbft on the RS Tuning rollers.
I think with the RS2 and 50mm extensions I could make some more power and extend the torque curve a bit.
But its a big risk when I know I could just go for ITBs and make the numbers.
I've overlayed our graphs, although yours holds on for a bit longer.

Just an update, after looking at various graphs especially Ph1Toms ^iv decided on just getting matched inlets with my current mods and spending rest on suspension refresh and is now booked in at RS Tuning for Tuesday 17th so will post graph once I get it back. Still tempted by RS2 maybe later down line and at least will have a graph can overlay to compare differences. If I had choice again would have been much happier going for RS2 and leaving car standard as the results people are getting on this look really well.
Thanks for people's input and advice on RS2 and links people provided.
