New to Mini-turbo-S/C question

Forced induction allows more power with smaller displacement and fuel doing it. It also provides torque over the na motor. Honda is a good example. High hp low torque. Also the higher rpm uses more fuel and that is where the na makes it's power

 

Remember we are talking about one of the smallest (1.6L) I-4 being used today. Only way to get any real affordable power out of them is to used a forced induction system.

 

The muscle car guys always seem to say, "There is no replacement for displacement."

I disagree, its called forced induction. As mrntd said above, using a turbo or super on a smaller engine is more efficient than a larger higher reving engine. For example, I used to have a 94 Honda Del Sol VTEC, a sweet little car, and it had the B16A3 engine in it, or a NA 1.6 that from the factory put out 160 HP, only slightly less than my 2010 MCS putting out 171 hp. With the mods my Del Sol had, lets just call the HP even at 171 +/- 5. Even with the same power output and the fact my MCS outweighs the Del Sol by nearly 300 pounds, the MCS gets the power so much faster and would eat that Del Sol alive. Now I don't know how the top speeds compare as I am not as bold in my early 30's as I was in my early 20's and have no idea where my MCS will stop accelerating. But I do recall white knuckling the steering wheel in the Del Sol as the needle topped out at 135 and felt like it was ready to fly off the road any second.

In short, I like turbo much better than NA! LOL

 

Have you driven a regular Cooper aka justa? The difference in performance between the justa & S is very big. When you add in the difference justa to JCW it is huge. You'll be happy with your new countryguy. :yesnod:

 

1.6L is not a lot of volume. It's hard to compare against something like a 1.8L Toyota or Honda that rev all the way to 8500rpm, make ~180bhp, but have very weak torque numbers. To get performance and good fuel economy, some method of supercharging is required.

It is no surprise BMW elected to switch from a supercharger to a turbocharger between the 1st & 2nd gen MINIs. Put all the performance talk aside, it was emissions and fuel economy pressure from the public and regulatory bodies. That is today's market driver.

This is why you only see roots or screw type superchargers on very high new cars these days. The people buying these cars could give a crap about fuel economy. Turbos are going to be commonplace in gasoline engines till the demise of the internal combustion engine.

 

Direct injection was also a major part of the gain in power and efficiency.

 

It would be nice to see Detroit rise again, and there are indications of an uprise, but the citizens of Detroit have been making their own bed for 40+ years.

 

I got a speeding ticket at 130 and didn't even know I was over 100.



Having said that, a boosted small engine is far more complex than a NA engine. So for cheap horsepower, and at the expense of fuel economy, the quote "there is no replacement for displaement" holds true.

 

That's true. And you can increase the displacement of the MINI engine to 1.8L with good performance and reliability. It's not a huge increase, but people get some pretty good numbers with that setup (but still with forced induction in the mix).

But another consideration is weight. Forced induction is also attractive in what it adds to a small block without weighing a ton. Otherwise, you're going to need a couple more cylinders and a ton more weight.

I got a 6 point ticket--the same as a DWI, and halfway to a two year license suspension, all in one ticket--bedding in brakes in the middle of nowhere, out in the country on lightly traveled roads in the middle of farm fields. What the hell he was doing out there is beyond me. Probably the only crime committed in that area of Wisconsin since it became a state.

 

Wow what was the cost of that ticket?

 

$265.00

And that was about 5 years ago.

 

Wisconsin - get the milking $$

130! Can't even go 10 over in Wisconsin if you have a MN plate. Like having a $$ target painted on you.....:arf: moo me baby!

 

I was only 61 over. Should be a dollar a MPH in my book. Cop didn't go for that though. When he asked me if I knew what the speed limit was where I was at, I blurted out, "at this point, does it really matter?" At least I got a laugh for that. No sympathy, but at least a chuckle.

The court offered to cut the points and fine in half if I took a court approved driving class. Nothing good was going to come out of that; it probably would have left me with more points and fines. I guess all those HPDE's I did before the ticket didn't count.

My main concern was my insurance, which didn't change a penny. No previous tickets, and a ton of stuff insured through one company, and they let it slide, provided no more crazy tickets. My driving record has been squeaky clean since.

Needless to say, no more bedding in brakes on abandoned country roads...



Oh, and you know why Iowa doesn't have a professional football team, right?

Because if they had one, Minnesota would want one too.

 

I got the ticket in Utah. The fine was $62. The officer was nice enough to write I was doing less than 100mph. That's one less round of golf for me.

 

Your example is one reason I live in California. Except for the smog laws, which I despise, we typically drive 70-80 mph....without issue. If you're weaving around, acting stupid then they'll get ya. Since we cruise around so fast anyway, hitting 100+ isn't that difficult, but not smart because our fees are also high.
