Thats a good answer. Thanks!

 

Sorry, that's not what I meant, I can see how what I said could be misconstrued, and i've removed that post to limit confusion. I drive my car every day on the street, as does Longboard (I think?).

I was just saying, people don't dump thousands on a system like this so they can drive 35 mph and rev their engines up to 3500 RPM's. As Jan noted, it won't be instant on torque like Twincharge, but it's a much more reliable system, that runs less boost, at lower temperatures.

I didn't mean that it won't be livable on the street, just that the primary focus isn't max torque at 1500 RPM's and the engine dying at 5000+ (R56?).

Seems as though people are expecting a huge amount of torque down low, and feel that it's not justifiable to upgrade the SC unless that happens . Torque is for towing and spinning your wheels, Horsepower wins races .

Most of what I'm saying is based on my own observations, Jan isn't piping me information to disseminate, so as he said, unless he said it, I wouldn't worry about it .

Sorry for any confusion .

 

Hey no prob. . Thanks for the response, Jan and Longboard kinda explained already .

 

I know, but the way that was written conveyed something completely different than what I had originally intended, so I felt I needed to explain .

 

Amen amen amen amen amen!

I am so tired of the "I want more TQ" thing... it's a 4 banger! you want big TQ ay 1000 rpms? then you should have bought a mustang! REV this baby out!! she wants to sing from 4500 to whatever she can go to....

 

I'm really tempted to have Jan bump me up to 8500 instead of 8k, I'm concerned about the transmission though. Danny said he had trouble shifting at 8k, said he had to finesse the shifter in . He's beat the hell out of his car though, so I wouldn't be surprised if his synchros are worn down quite a bit (I know his clutch is... ).

More peak torque would be nice, but I don't care where it comes in, I'm usually above 4k most of the time anyway, I rarely drive around on the street in anything higher than 4th gear, unless i'm trying to avoid attention or in "Economy Mode" (Never seems to last long , it's just too tempting)

 

that's because he hasn't got the Clutchmaster clutch....

he will have it by the end of the week

 

You know, back before I knew you I had a life... and money. Now i'm like some crack addict, waiting for his next fix, spending 3-4 nights a week at Danny's shop hanging out. Every week you come out with something else that I just HAVE to get .

Any reason you chose 8000 for the rev limit instead of higher? The valvetrain is obviously rated to handle much higher, so what's the weak link?

 

yeah I have seen this trouble as well... coming out of the gear is not problem... getting in to the next one can be troublesome....

I am the same... I cruise around at 4K... it's a happy place... and I get great mileage too...

 

0-60 in under 6 seconds and 34 mpg on the freeway, I wouldn't have it any other way . 4k is very happy... the car likes being there. With my tires and 16's I cruise on the freeway right now at almost 3600, haha.

 

Possibly water pump cavitation at high RPM's or the Eaton SC is very inefficient at the upper ranges. Something the Rotrex with an electric water pump should address. But keep in mind as you tune for the upper ranges the bottom range seems to fall off. While the bottom end may handle increased revs, can it do it for long periods and at what does constant 4-8k running start to hurt expensive parts.

 

Yea, but Danny's running a 19% to 8k and has no issues *shrug*. We'll see, Danny and I added up my reciepts, it's scary, I could have bought another MINI! .

*Weigh's Options, Really fast MINI, or 2 mildly modded MINI's *

 

 

forgot to add the 2...

"2 Mildly Modded MINI's"

 

 

+1 for really fast mini.

 

No, he switched to the 15% like I told him and it runs even better

 

Hey Jan,

Just read this right now and couldn't wait till I call you tomorrow.

I knew there were going to be 2 versions, or so I thought, but didn't know nor do I know of the 2.0L version!!

Can you clarify as to the different versions and their HP differences and what is the 2.0L version or did I miss something?

 

2.0L Version = the stroker kit Jan developed for the MINI.
1.6L Version = Stock 1.6L displacement motor that comes standard on all the MINI's.

With displacement comes torque, so i'd expect with a 20% increase in displacement to see a significant jump in torque, even without the Rotrex in the picture.

 

By "stroker kit" do you mean the Rotrex that Jan has been working on?

Excuse the ignorant question.

 

Nope .

By stroker I mean he's increased the displacement of the stock 1.6 Liter motor to 2.0 liters. He's made the engine larger. The increased displacement means more torque and HP. The 20% increase is significant. For comparison, VWAG Recently refreshed their 1.8 liter turbocharged engine by enlarging it to 2.0 liters. That's only a 9% increase in displacement.

The current rotrex kit is being tested on a stock 1.6 liter displacement motor (I don't mean the motor is stock, just that it hasn't been stroked). There are plans to test a modified kit on a 2.0 liter "Stroked" motor, which should be interesting.

Bed time for me, I have to get up at 6 am for work .

 

Your backwards, the saying is "Horsepower sells cars and torque wins races"

 

I thought Jan was working on several solutions for more torque. I have an automatic for stop and go traffic and a little more torque would be usefull. I'm a little concerned that after I get my head that the torque under 2k will be much worse. I thought he was working on a kit with a different rotex size as well as custom camshafts. The 2.0 would be great but from previous posts my impression was that it was expensive ( I hope I'm wrong).

 

Unfortunately though, you don't go anywhere without torque...

I'm all for high horsepower, but your need good torque numbers too, and frankly I feel that anything under 200 ft/lbs tq. is useless...you might as well be a Honda...

Atleast that's how I was raised...(my $.02)

 

I have a torque cam that I did and I will be tuning that after I finish some of these other projects. My head doesn't kill low end torque, that is a myth.
I have numerous projects that will address the needs from tame to full racing
