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...
Booked to have it all fitted on 22nd.
It's only costing £200 to have them fit the sports cat (people that have done it themselves have taken anything up to five hours!), remove the cambelt and adjust the cam timing, and upload the new MR230 map. Bargain!
ASAP. As it can only be fitted by a Mountune 'Pro' dealer I'm limited to two that are within easy reach. It'll likely be sometime in January, no idea when though.
Looking at the power and torque curves (standard versus MP215 versus MR230) it's more what it does to the power than the torque...
I bought my 172 Cup brand new...and got it to something like 100k miles in 4 years, mostly commuting but included approx 30 trackdays. In that time I changed pads for something more suitable, better brake fluid, and braided lines only.
Standard seats, standard suspension, standard everything...
Right, a shakedown has revealed all is good. May well be the placebo effect, but recirc valve noise seems a little more audible, and a logging session has shown it to now regularly hit 1.46 bar versus a previous max of 1.44. Unsurprisingly intake temps are lower than anything I've seen...
I fitted my induction hose this afternoon, then in a moment of madness spurred on by the successful hose installation I decided to have a go at fitting the intercooler as well...I got there in the end...
Nice. I've always thought acceptance and appreciation of these devices would gather momentum as time went on.
They're available for reasonable money too...makes Apple's version LOL laughable.
I'm going to wait a few more iterations before I jump in I think...I like my Raymond Weil far too much.
I counted the word "obviously" being used for things that are completely not obvious about 500 times in that video, that's worse than listening to a Phil Glew commentary FFS.
Annoying.
So it's been an uneventful few months, rapidly approaching 46k mile in it now, still enjoying it. New job from next week means annual mileage will drop from 18k to 11k which means I'll be happy to hold on to it for longer than originally planned.
With that in mind I grabbed this in the annual...
