A good result then James, more than what the car got at Jamsport then.......................

What was there setup like there out of interest mate?

 

on run 2 & 3 it made less power at AMD if you compare the graph from the rolling road thread.

 

Setup looked A1 first class very modern and new.

 

Nice one James,

You should post your new graph up to compare it with the other one maybe

 

Good result mate

 

This graph has a longer duration than your Jamsport one

 

Good numbers James....next shoot out at AMD ???

 

And more local. Well for the Essex boys

James what did AMD charge you?

 

the RR debate rumbles on

as ive always maintained accuracy can only be measured by testing at the same set of rollers during the life cycle of mods you do to your car , even then you have to make allowances for temp , humidity, tyre pressures , fuel used etc etc

despite having figures i believe we can back up to show further improvements to our car im not guaranteeing anything until i can get back to my usual dyno and try and replicate my earlier test as closely as possible , i dont believe using various rollers clarifies anything. The average man will always say the highest figure is the right one and who can blame him for that

cheers

On another note: What is mostly used in the UK? Dynojet, DynoDynamics, or something else? Personally, I believe hub dynos to be more accurate, but I could be wrong.

 

I think statistically it would be fair to admit Mountune have fulfilled all their claims about their package though.... wouldn't it?

 

id say so. the main thing for me is developing the power that they say they are going to produce

 

The good old dyno debate!!

I can't see on this phone but what dyno do and use? Any hub dyno I've seen over here is like firing darts at a random set of numbers in terms of accuracy. All synod can be fudged but some are easier than others. For example, put a dd roller into 'shootout' and it assumes that the tyres are inflated to 50psi. When in reality (unless the operator has inflated your tyres to this) they will be running much less pressure...hey presto, the dyno gives ya a wee bit more power. Dastek can't be fooled in this way.

You say that the numbers drop off in runs 2 and three. This could be heatsoak but it could be the car trying to preserve itself-remember not every generic map will work great on every car. You could have a map that has too much boost which makes crackin figures and feels great on the road because it only gets the odd blip.

I've seen cars virtually shut down on the rollers because of generic mapping tools (not mountune).

Did the operator have a headset or any monitoring gear on the car to see if there was excessive knock?

 

Mate to be honest i have not a clue what they done all i done was hang back and watch the car on the rollers, the guy did have a headset on and a wireless keyboard but good no's what he was doing?

All i no is that the car had 3 runs and then was shown the figures at the end at which time the bloke said runs 2 and 3 are down to be it being to hot and that it happens all the time on there dyno and they had seen this countless time on tuned and non-tuned RS's at there place...?

 

James great figures mate. I'd be pleased with that.

 

is it because of this fuel pump? to supply these figures, I don't know much about tuning - but that does seem to be making the difference

 

Excellent results

I would imagine results 2 & 3 were down to the car saying "hang on a minute, its getting a bit hot in here" so nothing to worry about there. I would even go as far as to say that out on the open road the Mountune will make even more power than on test one as going by my days back on the focusstoc forum the moutune cars were always very good on power

 

Guys - now the MP350s have been used for a while, can anyone tell me if there is a noticeable improvement in sound over the standard car? I know Mountune will have a cat-back system available soon, but I was hoping the £2k kit might make it sound more aggressive?

 

Perhaps it's just my ears but I think my RS500 sounds slightly more gruff than my standard RS did. Not that the old car needed "improving" in this department. My friends think it sounds different too so presumably so do the MP350s out there.

Cheers,

Phil

 

TBH i find my mountune car sounds just like the standard car, ok yes there might be a very slight bit more induction noise due to the new airbox but other than that i find my car sounds like the standard factory car in every way.

The cat-back exhausts that are coming out should give the mountune cars a nice new tone which i think it very much needs...?

 

Yep, I find exactly the same as James has. I've read so many people reckoning their car is louder with the Mountune kit but I have no idea where they're getting that from, induction noise included.

 

Agree mate i hear the same thing, but i can say hands down it dont it's the same as standard i think so anyway, and when i say a very slight bit more induction noise i really do mean a slight bit.

To me it's the standard car in every way just faster and that's it every thing else the same.

 

Mate i aint got a clue, i brang my car to get it dyno'd and got the results as for the rest i have no idea?

 

Thanks James and Arun for being honest about your Mountune'd cars. Having said that there is no noticeable noise, would you both say that the difference in power is significant? Does the power come in at the same revs as the standard car?

I love my RS, but find it hard to get it moving quickly without dropping gears to get it revving. I just wish some of the power came in lower down, with less lag, so the power delivery was smoother. I was hoping that the Mountune upgrade would help this?

Phil.

 

@quinvy, I have been surpised how the grade of the fuel effects the MP350. My car is much more responsive when using Tesco Momentum when compared to Esso Super. I will only use Vmax or Tesco Momentum from now on.

 

Thanks Jah, I only use Momentum myself. Does the power on your car come in any lower in the rev range than the standard car?

Phil.

 

Thanks Phil & Jah, I'm going to see if I can get a test drive in one.....

Phil.

 

I'm likely to be booking my car in for the MP350 upgrade later this month - something that is bugging me though is that no one has actually really raved about the kit? I remember upgrading my ST and everyone said how it totally transformed the car (which it did!!!) - not getting the same vibe for

upgrades

Is it a case that the MP350 is such a smooth, well sorted upgrade that you can't make a fuss about it? Tell me I won't be dissapointed?

 

Nail on head there mate, that's exactly why I've been asking the questions about it. I've booked a test drive in an MP350 car tomorrow so I'll let you know. The things that puts me off the upgrade are, 1. cost. it ain't cheap 2. my insurance want another £290 3. the road tax increases apparently 4. nobody has said it's fantastic. and 5. standard cars seem to be easier to sell.

Phil.

 

Yes I will Renny. Thanks for the advice on your experiences with re-sale values. This is my first, and probably [unless I win the lottery] last new car, so I have no experience to fall back on. I just hope the test drive isn't through the town centre traffic. Otherwise it will be pointless exercise.

Phil.

 

Thats what worries me going the Mountune route, most of my driving is below where the extra power is available.

Might hang on for awhile £2k is alot to spend.

 

I don't know mate. Like I said, there was too much traffic about to be able to use the high revs properly, and the strange stuttering on the motorway didn't exactly help the experience. Though I must add, the petrol warning light was on, and I think there was 45 miles to empty on the instrument panel.....mmmmm

Phil.

 

Btw, speaking of power in the lower rev range (say 1800-2500 rpm), it is important to remember that the boost threshold (not to be confused with turbo lag) for the standard turbo fitted to the RS seems to be around 2400ish rpm (my own brief observations). Below this rpm it will simply not be able to produce noticeably boost. An ever bigger turbo will normally have an even higher boost threshold.

 

I must admit I've enjoyed reading this link as I know James and know we both tuned our st's (I never went mountune as I wanted the 300bhp mark lol) but by all accounts the mountuned st was close to our 300 ones!.
I'm amazed that I still aint modded my RS, I'm coming up on 5000 miles and will deff say my car is quicker now than when new.

On a different note I had my mates renault megane sport running 260bhp for the day yesterday,,,It had the st feel of planting you into the seats and seemed much quicker than the RS,,,,however driving the same roads today in the RS I was deff quicker....
The mate got out of the RS and said hmmmmm thought that would have been quicker, so to me I really think the RS is going quicker than you actually think as it is so well set-up!

Once again good topic lads keep up the honest comments, and I know as soon as mountune bring out the exhausts I'll have it fitted hehe, as long as it's not a resonated Miltek!!!!!!!!!! hehe
