Wow. Good effort with the results, videos and pictures Tim!
Was a good day yesterday, weather was good for a February session, lots of friendly faces, lots of petrol related banter.
Mine's being serviced on Tuesday...I'm going back to Charlie ASAP after for another run...I know it has 230PS in it!
Also, after along weekend and lots of miles so far, I drove into our village to pick up a curry and almost decorated the inside of my car with it. I still can't quite work out how he didn't see me...
Take the reliable and consistent Surrey Rolling Road and add...
1. one MR230 2013 Fiesta ST
2. the dyno data file from previous run when MP215
3. a hardcopy graph from SRR comparing MP215 with standard
4. a ruler
5. a little help with the maths from Excel
4. one of my daughter's green felt tip...
F***, that was luck/unlucky. Glad all OK.
Congratulations on coming clean...is this a CS first?
Driver makes mistake. Driver admits driver made a mistake. Driver invites comments about driver making a mistake. Odd.
Its power is the same and its weight, its wheelbase, and its track are within kilos and millimetres of a Clio 200.
Only it's rear wheel drive, has a locking diff, and a centre of gravity 400 mm off the deck.
There's nothing wrong with that at all. The problem is everyone sees the price and...
More than worth it!
I brimmed the tank last night, reset the trip MPG, and today attempted my now traffic light strewn stop/start commute to see what I could squeeze out of it. 20 mile round trip to and from work and I now have just shy of 46 MPG showing. If anything I think MR230 has made it...
I stand corrected!
I can only find one unmanipulated data file where I hadn't converted the boost data to a percentage of maximum, and in 20 minutes of driving, going from tickover to limiter in each gear, I recorded a max boost of 1.33 bar.
So;
Standard = 1.33 bar
MP215 = 1.44 bar
MR230 =...
I never use it with dials/gauges etc. showing...I just use it to log the data then play about with it in RaceRender to overlay graphs, counters, and dials on top of video footage. Or as I have been recently, when just wanting to check boost levels and rev limits, I just log the data, export it...
If you've paid for it, it's Torque Pro.
It can only do so much on its own. Pair it with some video footage and RaceRender3 software and, for me anyway, I can lose days playing about with how I can view the data and seeing what I can learn from it all!
Mountune's figures...
Thinking about the rev range increase, that's probably behind why they can now claim a 5.9 second 0-60 sprint time for MR230...with the extra 500 rpm you can now reach 60 without a change to 3rd gear.
They quote 250 ft lbs but I had that with just MP215, and I had near...
OK, I've now picked through the data, here's a few of things I've found;
1. I didn't do any full throttle runs in 1st gear (zero traction) but managed a few in 2nd while struggling for traction. Boost wise, MP215 used to limit 2nd gear boost to 1.23 bar/17.8 psi, with MR230 you get 1.31...
Silver ST? As in body colour?
Today, taking advantage of the warm and dry weather, I whipped the front bumper off again, got it up on stands, and fitted the charge pipe kit...well, all except two short 8-10 cm pieces that require major disassembly at the front to get access, one is the branch...
Saturday 6th February, hopefully Charlie still has the previous run files and can overlay all 3, he's always had them in the past so shouldn't be a problem.
Judging by how it feels in gear it's got every one of the 20-30 HP Mountune promised.
I'm waiting for the wife to get back in it, cameras...
I'm glad to say it's pretty far from being a chav cannon. It sounds louder on the inside than it does from the outside. You can tell it's different from outside, but it's not shouty at all.
It's a superbly well made piece of kit, quite sad I can't look at it up close any more! They gave it to...
I remember reading that, black may be cooler but stands out as modified hence silver being the 'stealth' option.
I'm quite happy with how they've fitted the exhaust, it's central in the recess, sticks out just enough, and has not banged on anything once.
I'm not too sure on torques, I'll check later and let you know.
As for the upgrade, 6.5 hours later (I was only billed for 3 of that though) and it is complete.
I've just driven home, 50 miles...
When I got MP215 my first reaction was a bit meh, there was something there, but it wasn't...
Err, 200 v 215 v 230 PS? That's peak only. Throughout the full rpm range MR230 gives +20 to +30 PS over MP215. Apparently.
I'll find out for sure in a couple of weeks.
It turns out a gasket is missing from the Mountune kit for the exhaust and sports cat, they have one en route, looking like 1pm at the earliest.
FFS. Wouldn't be so bad if their coffee wasn't s**t.
Ha ha, yeah, I'm more than happy with the standard pipe.
Another owner i know has MR230 on his wife's car, says she barely notices the exhaust as it only really gets a bit shouty when under full load. Fingers crossed it's on the subtle side when just pootling about.
This morning having got up at the crack of dawn I'm now sat at the only Mountune Pro dealer in the South, MR230 gets fitted today.
I was hoping they could/would fit it all except the exhaust as I'm not after noise and the original item still has life left in it yet, but Mountune insist it's all...
If anyone that has an ST is looking for a simple, quick, and relatively inexpensive power gain, fit the Mountune induction hose.
JW Racing strapped an otherwise standard customer's ST to a hub dyno today after first replacing the Mountune item with a standard induction hose - they were trying...
