Drivetrain Opinions and Question About Mods (N18)
#77
Precisely my thoughts! I don't have a j-style spacer, just a straight one. I think it's more a matter of keeping it warm, but I'm not certain. The only way to REALLY know is to constantly be data logging through OBD and be able to see the raw sensor readings from the rear sensor while you're driving it hard vs driving it soft. You'd really have to know exactly what parameters you were looking for though, and I'm not entirely keen on all those specifics.
I'm thinking something like whatever Exhaust Depot used to wrap their DP: http://ep.yimg.com/ca/I/exhaustdepot_2180_4869801
Edit: Reading further, they used header wrap for the DP. I wonder if that would be the ticket to wrap the spacer and sensor?

Alternatively, we could try wrapping the sensor and spacer in a wrap of some sort to keep it hotter and see if that takes care of the CEL.

Well guys, I pulled the trigger during the just ended group buy from Helix and got their FMIC... Installed on Friday...
Looks like I'm ready for a more aggressive tune and some suspension mods.
Anyone heard of any roundabout estimates of HP numbers from an NM Stage 2 tune vs a (possible?) RMW/Jan tune?

I can tell you that NM stage 2 tune (along with my other mods) feels like a beast!!! I know that a month ago I stated that I was going to chill a bit to save up some money but the increased torque from the stage 2 tune has convinced me that I NEED a Quaife LSD. I going up to see Way and having that installed (along with a clutch while he's in there) on Friday. I'm also picking up a set of Koni Yellows and spacers to be installed here in Savannah. THEN I will be done... for the most part...

Apparently no one has dyno'd an N18 with bolt ons and NM Stage 2. LOL

MINI advertises the N18 MCS at 181hp if I remember correctly. Yes, I went directly to Stage 2. I have no idea what the who and/or torque is now. After the LSD goes in I'm going to schedule some dyne time. A shop here offers 3 runs for $100. When that happens, I'll post.
As far as the 172hp number, they were referring to at the wheels. MINI's 181hp advertised would be at the engine. Seems about right.

FWD cars and Manual Trans' inherently have much less drivetrain loss than RWD cars and Auto trans' do. Furthermore, drivetrain loss is not a static percentage, it increases with torque due to thrust forces in helical cut trans and differential gears, windage, seal drag etc...
http://www.modified.com/tech/modp-10...s/viewall.html
This is a great article. In it are some good points, one of which being
"... when dyno testing in the direct drive (1:1) gear, power is delivered directly through the mainshaft of the transmission, so the only loss sources are windage, friction and drag, resulting in total at-the-wheel losses as low as 1.5 to 2 percent..."
"In the case of FWD vehicles, the torque path is more direct to the front wheels and the use of efficient helical final drive gears means that drivetrain losses can be as much as 50 percent lower than on RWD and AWD vehicles."
That being said, 5% isn't impossible for manual transmission FWD cars with power output levels like ours. But what is really important to me are the deltas, the change between the first stock run of 172 and the modded run of 202. The 30hp increase is what I'm looking at, not the total output reading.

While I agree than 5% seems low, there are things to consider:

I was just impressed with the numbers lol =D
Deltas are probably most important then just big numbers because you need to see if the part you are adding is either gaining or losing power. Hence deltas.
For instance, the guys at AEM said their dyno reads low, but they only look for deltas, not peak numbers. I don't believe they were too happy with the numbers my car gave when the intake was fitted. Deltas were low....which sorta solidifies the argument that the stock intake assembly isn't bad at all.
......so now they are looking for a stock N18 S....they will most likely see bigger deltas with a bone stock car.
Still gonna read that article right now though lol.

Hey Tony
these people have the O2 sensor for $69
http://www.jmturbocoopers.com/O2-Sen...s-Adapter.html
I plan to use it with buying either the VIP catless DP or Milltek catless DP.
What do you think? Legit enough?

Theft, price hype, parking lot full of kids and xxl white t shirts, everyone is a gangster, no respect towards noobies, selling parts to a Honda owner is a huge hassle as most are teens, the desired chasis for a build have been whored out with rebuilt titles, fake copycat parts, drag racing centric. I still have a small type r tattoo on my back but luckily almost completely faded. If honda ever comes out with a true 3rd gen crx I will buy it. Not this hybrid crap they have now.

I know some people actually swap and build up some damn fast Hondas. But those are a rare breed.
Parts are super cheap though...maybe for a reason?
How do you like your mini compared to the Honda you use to drive/upgrade?

Haha so true. I only asked because....well LA is like the capital of riced out Hondas lol.

This will be my last post about it since it isn't my thread- I love the car so far. Still haven't installed the helix intercooler yet. I'm throwing parts at it too quickly and not getting used to the parts one at a time and learning about them. How do I like it compared to my old honda? Well the turbo is about 1/4 the sze of my last turbo but the interior and car feels more solid than any Honda I've been in. Bigger turbo= more problems. This block in the pic was bored out to 83mm with darten sleeves and blew up 3 times.
These cars are not about lego building horsepower and slapping a big turbo on them. It's about turning imo. Fack a straight line.

I'm running colder plugs. Jerry T from NM recommended them. I got them from Way Motor Works
Talked to Jerry and Way and they both said run them once I go to Stage 2. So I'm gonna be ordering them this coming weekend so I'll have them for next weekend when I get back from vacation... that way I can just drop in the Stage 2 ECU and throw the plugs in it at the same time, start it up and roll out! POWERRR!
Surprised more people don't talk about running colder plugs if both of these guys (obviously with respected opinions) are so quick to advocate their use.

As you can now see in my sig block, I am now the proud owner of a Quaife LSD. LOVING IT!!! The tune gave me so much torque that I about couldn't stand it. Strongly recommended!
