These are IMHO, CONSERVATIVE estimates for HP with mods. The 205hp plan offers a very significant change for less than $800.


Recipe for 175 FWHP (205 Flywheel HP)



EXHAUST:

$200 for the OBX header from ebay as seen here:
https://www.northamericanmotoring.co...ad.php?t=36431

Install how to:
https://www.northamericanmotoring.co...ead.php?t=5403


$60 for the "one ball" exhaust mod. They chop off one muffler. This could be
done locally.

Cost= $260



PULLEY:

Full 15% pulley (use 15% for reliability) DIY install instructions with pictures. Also something to note,
Randy at webb will loan the tool to remove the pulley for free when you buy
a pulley from him : )

Install how to:
https://www.northamericanmotoring.co...ead.php?t=8466

Cost= $120


Alta lightened crank pulley (3% Oversized). Reduces rotating wieght by 6#'s.

Cost= $150



ECU:

Buy the MTH Software and cable set.

There is a full thread about this on NAM :
https://www.northamericanmotoring.co...t=37383&page=1

Cost= $140



IGNITION:

One heat range colder NGK spark plugs.

Cost= $10



INTAKE:

"Hot air intake". Use the RU-1540 and small breather.

Cost= $60





TOTAL COST= $740

TOTAL HP= 45hp

That's $16.27/hp


Note: 230hp version has been removed untill further R&D is completed.

 

better duck

 

When I do upgrades I also have to pay for:

Shipping to Hawaii-
Small light stuff about $25 to $35 a box (NO kidding)
For heavy stuff about $1 to $2 a pound at least. Like $65 to $95 per cat back exhaust!

Labor! What's your best guess of hours spent installing these?
A professional can do the installs fairly quickly but a beginner could take much much longer.

Cost of making errors! If you DIY you'd be supplying yourself with a labor warranty. Or fix your own mistakes (hopefully very few are made).

 

Thank you for the informative ideas on performance additions.
I got a few of those items on the way. M7 AGS and MTH. Other items will hopefully come in time when the money comes

I called a local MINI dealer who will install MINImania parts and wants $600 for a 15% pulley installed add a intake and the cost is around $1k

I think I will either shop around or learn how to do it myself . Installing an intake should be ok but the pulley will take some learnin' on my part.

 

Another idea, talk to Helix. They are in Philly and I am pretty sure it would be worth the drive to get the savings. They can also Dyno your MINI to check the results. The cheapest way to go is finding a pulley party. That is how I got mine installed. The AGS should pretty easy to install yourself.

 

Have the HP gains listed been documented together installed in the same MCS on a single dyno run?

I ask because the notion of adding-up individual component HP gain claims and assuming that their sum will be seen on a dyno is not based in fact. My apologies if this is not the case.

You forgot to add the price of several large grains of salt.

My thoughts exactly. These look good on paper, but it doesn't work like that.

 

we will find out what Injectors/GIAC Ecu Flash/17% Pulley brings in once I get it done in the next week or so I plan to dyno before and after.

 

I mod'ed my MCS seeking cheapest ponies available and took this approach - CAI (180) + 15% pulley (125) + 1 Ball Exhaust (125) = 430 in parts. The figure I am missing are DYNO numbers to calculate actual cost per pony added.

I think these are the cheapest ponies money can buy!.. I am trying to find a place near Miami, Florida to dyno the car (any suggestions where to go?).

The only other things, I have done was to complement the engine mods with a new rear sway bar (highly recommend) and a boost guage for visual entertainment value to go with the whine.

All in all, I have a little over 1,000 invested (had everything installed - don't have the tools or time) and am extremely happy with the results for daily driving purposes.

 

What an odd list...

Since this is apparently just speculation on your part, I would have preferred to see it listed as such as opposed to coming off like a factual how-to.

If you've actually done it, and proven the gains then I appologize for misunderstanding.

 

This list is what I am planning for my MCS. I will go for the 15% pulley as it seems to offer a nice increase in HP while keeping the car streetable and most importantly, reliable.
I was thinking about the JCW air box but I guess I need to read more about the Alta.
Can you please explain the 1 ball exhaust? How is it modified and what does it sound like.
My MCS is an 05.
Thanks

 

LOL that's funny...

Like cooking there are variations to a recipe and some cooks would say different....

so what...do what you think is best...I do what I think is strongest with the most reliablility based on an engine....not a MINI but an engine...

 

Yes the final HP number is for all of the mods combined. There are plenty of dyno results out there to back up the 205 plan, just find a MCS with intake, exhaust, ECU, and 19% pulley. I took the time to link them in the last thread but since this is NAM, dyno results weren't good enough

I posted this as an easy guide to what works and what is cost effective. Yes, you have to install everything yourself. NO, it's not really that hard. The hardest thing is the pulley but in reality most backyard mechanics could pull it off. The only other thing to install is the header and that is fairly easily.

I have my flame suit on so hit me with ur best shot

 

They chop off the left rear muffler. You lose some restriction but the main benefit is dropping about 25#. It sounds about the same, a tad bit deeper and more raspy.

 

I don't recall seeing dyno results backing up most of what you posted, and certainly not cumulative ones for those combinations of mods. Some of your statements make no sense like:

If you are trying to add these gains above and beyond the HAI, surely you have noticed that the air intake path of the HAI is MUCH shorter than stock, about the same as the AGS (since the AGS uses a different style of filter). Surely you must have also noticed that the quoted "21% Increase in air flow" was not for the AGS, only for one part of it. I have seen no such data for the entire system ... it may very well flow worse than the AGS and it could even flow worse than stock (doubtful, IMHO). Finally, where do you get the 10hp/10#tq figure on top of the gains already achieved by the HAI?

 

Great question. The cumulative value is always a big ?

 

Is it really the left rear that is taken off? When we removed the exhaust it was explained that the right rear 'muffler' was actually the resonator, so I'd think that would be the one to remove.

Anyhow, I was happy to take that ugly heavy thing off and put on the JCW with its nice shiny lighter resonator, 2 muffler set up :smile:

 

I never said the HAI gave any gains. Im pretty sure the M7 AGS with give 10hp over a stock setup.

I don't really want to do this AGAIN but I will. Where's that damn search button.....

 

OH NO, it's METRIC!!!!!!!!!!!
To convert metric units:
1 kW = 1,341 HP ; 1,3557 Nm = 1 lb ft


2003 MCS, 56,5mm pully, mth ecu, beru spakplugs, k+n CAI and remus exhaust.

These HP numbers are from the butt-dyno They smell like it too

 

I'm still not following you. You said:

one-ball and header = 10hp/15#tq
pulley = 15hp/10#tq
Crank pulley = ???
ecu = 5hp/5#tq
plugs = ???
HAI = ???

Total = 45 hp

Are all 3 of the blank items responsible for the extra 10 hp?

Then you said:

AGS = 10hp/10#tq
GRS IC = 10hp/10#tq
Injectors = ???

Total 25 hp

Then you added both together to get 70 hp. I don't see how the dyno you posted relates to either the 45 hp or the 70 hp gains you listed.

 

Ok, im sorry I don't know the EXACT breakdown for the power EACH mod gives the car when combined.

Look at the MANY dynos that have been posted on this board and they will equal out.

If you're such a genious, why don't you prove me wrong?

Show me a dyno of a properly tuned car with an MTH, 19% pulley, Intake, colder plugs and exhaust WITH header that dyno'd under 175hp.

 

Whoa! Relax. All I was doing was trying to find out where/how you arrived at the numbers you did. No need to get so defensive. Sorry for posting in your thread.
