... performance mods?

 

End of run is 120mph

 

Alright so heres the deal. I want a MC for a commuter car. I intend to add turbo and other moderate mods to it over time. Im currently looking at a 05. Its not an S. Does the MC have variable valve timing? And if not should I buy an S and convert it to turbo. I know its supercharged but I dont want the parasitic loss of power from a supercharger. Id like to get to 10 HP per pound.

 

WTH? What do you really want from your MINI? Great MPG? Dependability? getting an S and converting it to a turbo sounds like a very expensive way to get a R56.

Its gonna start out as a commuter. And i want to modify it as i go and then itll be my sh!# kicker. Im just now getting into this thing with Minis. I wanna get informed before i jump in. Thats why i wanna know if The 05 MC has VVT. Ive always wanted one cuz it looks like it handles like its on rails with the wheel positioning. Now im in a position to get one and i wanna do my homework.

 

The S model would definitely be a better base with the added benefit of oiling features the MC doesn't have. Plus, you have a bottom end already setup to take boost and more support in the aftermarket for it. If you're set on putting a lot of money into a MC to bring it to MCS specs, research transmissions and determine the build date for the switch from the Midlands to Getrag.

What's your hang up on VVT?

 

Start with an S! The Cooper bottom end cant take boost, the 5 speed cant take power, the ECU will be harder to get tuned right.... And the list continues.

No VVT on any first gen MINI. Its a stone age Chrysler designed engine.

None of what you are wanting to do is going to be cheap... We are talking doubling the price of the MINI (NEW car sticker price) in order to do it and get it right.

 

Eeehhh.... subjective to what you call "right".

 

Well I defenetly know how to do it wrong...

 

Some progress with my R50, 8000rpm

 

sounds so good!

 

Made 158hp in the final run with some improvements in the map, but we lost that file by mistake, so here's the before final. Still lots to improve.

 

Sorry... wrong forum

 

Is there any one location where the most popular mods and their estimated (or proven) hp are listed? I feel like that would be a great resource and would save a lot of time searching forums (and save the regulars from having to do with the constant repeat threads).

 

I feel like an idiot for asking, but is there an ECU remap tool that's compatible with mac? The only ECU tools I've found are windows compatible

 

Same here!

I'd love to have an R50 with ITB's like that --- I've sorta finally gotten used to the detached numbfeel of DBW, but still find myself irked sometimes by its inherent lack of tactility.

Wayback Machine has archived the old HPAm site:

They were in Vancouver Canada.

The old page shows different wheels fitted but I much prefer those in the photos seen here as I've always been partial to 4 spokes and those look good in my eye,
Axis Maglite in a 17" I think?




Fairly rare rims it seems after looking into them,
and citations of weight were variable according to source apparently...

...but,
I digress as usual into tangential twistcurve,
back to the ITB business ---
just from a quick look it doesn't seem like many people have done this as the expense/difficulty is pretty intense.

Hey @nickbmw !

I love your 8kRPM video and it shows a lot of hard work to get it up to that spec and read on MT that you were planning on the ITB's to push it further along...

...saw the set that you had test fitted some up,
ever get them fully installed?



What all would be required in order to properly set up ITB's?

Here's a kit from Jenvey Dynamics in the UK,
what do they mean by "early square ported engine"?

 

I too thought that 8K video was impressive. He also has a final dyno pull video & one of the replies he made there was:

Stock valves break at the stem, fall in and destroy the engine. A built R50/W10 needs at least R53 valves. I had a complete Cosworth head, that included Ferrea +1.25mm valves. Small 260/260 Kent camshaft. I tested about 10 camshafts. Also R53 block/crankshaft/rods with custom Arias high compression pistons. I had itbs and a 300/300 Newman cam to throw on, aiming at 180-190 hp, along with mechanical lifters, but i never completed it as i sold it and bought an S2000. This power was made on a custom single throttle body intake manifold. Stock manifold chockes the engine as it's made to resonate at around 4.5k rpm.

Thats ^ posted on his last video. His dyno pull video info states:

"8150rpm rev limit, this was a baseline dyno session for next mods along some fine tuning of the map at the current state, 158,3hp at 7400rpm and 15,7kg/m torque at 6500rpm."

So 158 hp & about 153 nm of torque. Possibly 175 at the crank by revving to 8k. Looking at his road pull video it had some serious rev-out going on, definitely a free breathing engine that also has a lightweight flywheel - but also has the heavy ATI crank pulley. He says his pistons were custom so its anyone guess what capacity he was running. But an impressive R50 absolutely!
