1st Gen R53 Cooper S 250-260 WHP on a m45 Blower..

subscribed to this!

Could people possibly also post what they are tuning or got tuned with? I am new to Mini's so I am VERY interested in getting my fingers into tuning software for them!

 

Post pix/details of your setup pleassssee :biggrin5:

 

I could only manage 247, I feel so inadequate....:wink:


That was on a superflow dyno though--they read low--maybe I'll run it on a dynapack on a cooler day sometime, so I can claim 250 WHP...

Here's my measly results:

Oh well. Back to the drawing board I guess.:ihih:

 

It begs the question: Would you rather nitrous for quick bursts of HP, maybe get above 250 for brief periods of time, or have constant power, just south of 250?

In the end, 250 is just a number, but I suspect it wasn't chosen arbitrarily (If you dropped the number to 240, and maybe Nate starts the thread, the outcome is radically different). There are plenty of cars of hovering around the 240-250 HP range, with the combo you mentioned, but yeah, above 250 is more difficult (although if I put my car on a more favorable dyno I'd get above 250). That being said, there are cars out there above 250 with that combo.

But most people shooting to get above 250 are aiming even higher--250 is kind of no mans land, because it's not guaranteed to hit with that combo, and the next step up gets most people way above that number....There are reliable ways to get there, and not so reliable ways to get there.

To be honest, I've seen many cars with head, header, cam and exhaust mods. I haven't seen a single car running nitrous. Not saying there's anything wrong with nitrous, but I suspect the majority of people are looking for consistent power rather than short bursts. Just my .02 cents....

 

We've got a few cars with that kind of power with the M45 and stock compression. The problem is that it is very expensive, and very loud.

I think another reason you don't find many people wanting to post about is cause people just want to rip them apart. Also they know the car really makes that power so they don't need to prove it on the forums.

 

I don't think it is a younger vs older mindset when it comes to the bottle. There are lots of Honda's out there owned by younger folks that have Nitrous. What it comes down to is the intended use of the vehicle. MINIs, for the most part, don't lend themselves to be a straight line car, not that a Honda really does either, but that is where a decent sized contingent in the Honda community have gone with their cars. There are a few out there that did or still are running MINIs a 1/4 mile at a time but they are the vast minority when it comes to the Modded MINI community.

In the end this make is more difficult to reach the 250 whp level that this thread is looking for.

While M/A is more friendly than most forums there is still this underlying nasty theme that runs through the community as evidenced by this same subject on MINITorque.

There are some high powered 250WHP+ MINIs out there. The people that own them for the most part have been so beat up that frankly they have moved away being forum contributors. It's one thing to question and ask for details, it's another to reach down to depths of personal attacks that threads such as this often descend into. I don't blame those that have achieved this level from not wanting to be flamed.

 

I made 260whp and 209ish wtq I want to say or 206wtq maybe. I forgot its been a year. Jan can correct it. This is on the stock exhaust and a fully built RMW motor with stock compression.

Then I made 240 at 6k elevation and 12lbs of boost and the Vipec.

 

I did 267 on a stock motor with over 80k on the clock. The head it EXTREAMLY lightly port matched and thats it. I have a decatted stock manifold, 2.25" exhaust, one ball muffler, +5% pulley (larger), 650cc EV14 injectors, custom piggyback controller, 18psi boost. This was on Helix's Mustang dyno. Oh and a 60-1 turbo in the rear 8^).

I have since reworked the vacuum lines and turbo controller so I have more midrange torque/boost. I need to redyno and then get a ported head/pistons.

 

lol

 

Wow a 60-1 is kinda big for these things wouldnt ya say?
