Cai's wont get you much if anything, Downpipes w/out a tune will get you some but they are not put to full use because the output levels of exhaust are not increasing. A tune alone will get you much more than just those two mods alone.

 

The cars that were modded with downpipes and exhausts from that group of dynos were also tuned. So my big surprise is that even WITH a tune that those cars did not show any significant increase and in fact made less power than the one MCS that had a tune listed as its only mod. More importantly, the MCS with tune only has a much better torque curve than the other MCS cars with the additional mods.

So, just using that sample of cars, it doesn't seem worth the extra cost in parts and labor and performance was negligible.

 

waste of money just sound nice. the DP will get you some juice up top though.

 

Finished reading this a couple hours ago. I don't claim to have the highest HP, but I'm driving my 282 HP all around town, on freeways, and over the Sierra Nevada's --- sometimes "punching it", sometimes using cruise control. So far, there have been no breakdowns.

I question the validity of just how good is this 320HP package. My dyno experience was several runs of gradual acceleration. Has this 320 HP machine been put on the street and exercised? Someone mentioned the lack of a clutch change. I'm still getting used to my Giken parts, but my OEM clutch was still OK when it was changed, and it had 5 - 6000 miles on my other mods --- it needed an LSD so why not do the clutch / flywheel while in there! No added HP, just performance improvements.

Someone else mentioned how easy it is to add HP. I agree for most of the "bolt-ons", but not all of us DIYers have access to the specialized tools / equipment to get into the engine. I paid professionals to swap the head, do the Giken install, and do the dyno tune. My bolt-ons, including the Garrett, were put on by yours truly --- one hell of a learning experience!

Dyno's --- sure, there's going to be errors in the results, and different dynos will produce different results. At least they create documented results. No comparison to the butt-dyno. Arguing about a few HP differences is pointless. It's the driving that counts. A good driver with a stock JCW could probably beat my MCS with me driving it - track or strip. But they won't be having near the fun I'm having!

Someone else seemed to be bad-mouthing the level of talent using this forum. There's a lot of new, inexperienced people buying these Minis, myself included. Where else can we get info about upgrades, performance, trends, etc? Dealers have the knowledge, but no time to spend if not selling one. Yes, there's also the window-sticker crowd. Good for entertainment. I've always preferred the "sleeper" effect. Don't want to attract a lot of attention on the streets.

I'm not thru with the upgrades yet, but I need more time to get familiar with how it handles on the streets (new clutch handles a lot different). I've documented my upgrade process with a PDF attachment in other threads. Have yet to add Giken to this PDF.

Like this thread originator, I'm interested in where the HP limits are, and what it takes to get there --- when does the crank give up? Rods and pistons? Gears? Pics don't help --- interesting, but useless unless copying.

I'd really like to hear from others that have some serious HP --- what it took, how they got there, and is it reliable?

 

^^^^ The problem with people here is that there is a small group of owners that are willing to go the distance to see what the limits are. The problem is there are very few of those who have the funds to do that. Then there are the vendors that have the funds/knowledge that don't post here because they have better things to do. The largest group and the ones that are really slowing the progress of were MINI modding. They are the group that says that has to neigh say everyone who has any kind of power or idea. They are the group that say it is impossible to get any power out this car. I could go on but, I am pretty you understand what I am talking about.

 

Pics of the GT28RS??

 

Ive got everyone beat, after replacing the watercooled turbomuffler bearings, I ordered and installed custom Unobtanium piston return springs and a 700 hit of nitrous, and if I happen to run up against an honest to Gd Skyline GTR I just thumb the JATO rockets I stole off an old C130 out in the Monthan Davis boneyard. 0 to 547 MPH in about 6 seconds, courtesy of 18K LBS of thrust (I have 2). Fabb'ing the brackets sure was a b%$^ch though.

 

Nice try... sorry no LOL from me.

 

Come on. Give him at least +1/2........

 

Fake supercharger with a carb inside the hollow compessor. may have 500 bhp.

 

Jcw clutch is pretty stout although mine was replaced with a giken gran touring and installed a quaife diff.

 

It is up to the client to market the product my shop gets paid for development and testing.

 

Car runs like the oem developed it.

I see one of my shop clients mentioned in your post.

 

10,000 miles of drivability testing.Drives so nice you would think mini/bmw did the work. full boost @2300 rpm and makes power all the way to 7000 rpm.

 

Not really. 28,500 miles on my JCW and it was completely burned up. Dealer replaced it under a one time good will repair. Should have had them put in the OS Giken GT clutch.

How is that clutch when used on a daily driver?

 

Depends on how rough you are with engagement and how hot the clutch/flywheel surfaces get,for dyno work it is just fine.

 

I like the stock clutch for street use.stock clutch can hold 300ish wtq before slipping. when using stock clutch it is better to spin the tires vs sliding the clutch.

 

Here we go again.

 

Well mine did not last for long with 275wtq.

 

1-6= 5 shifts and 5 engagments=more heat on clutch and flywheel faces.do you know how to float (matching rpm to road/inputshaft speed)?

 

A less restrictive downpipe will produce gains from bottom to top.less restriction= quicker spool.

 

Stock JCW clutch holds more torque than the OS Giken STR setup, can't speak for the GT setup.

 

You know I thought I burned up my clutch at 60kish. I was dead wrong. I went and got the OS Giken cluctch and flywheel combo and low and behold it wasn't the clutch that was burned up it was the dual mass flywheel that broke. With any kind of force it was moving a sold 3 to 4 inches in either direction and it had burn marks from where my got stuck and road the clutch out. I wasn't able to make it to Orlando this weekend because I had to work and I have to work nextweekend also. But I am still calling BS because if you had this car you would have come out to Mickey and MINI a couple weeks back because it was right down the road. Even if you didn't pop the hood. I will give you the benefit of doubt though because you might be telling the truth but then again this is the internet and everything on the internet is lies.



















That includes everything I said or is it?

Mini's are not the most important part of my life, my daughter is the most important thing in my life.

 

Really......realllly! That is what you got from what I said? Wow just wow. I would never expect anyone to hold their car over their family even though I have seen it.
