hey guys!! im sorta new at this and need some advice please! i wanna make my mini cooper s fast!! my first car! gunna have it for a while!! ive already out an agressive borla cat back exhaust system, k&n filter and have installed a 15% sc reduction pulley!! what else can i do for it without costing me over $3000.?? if i get injectors and a 2% crank pulley and header? will my motor be okay with it?? or do i need to do other things for it to handle the extra power?
looking for anyway to make it faster and not kill it!! gotta keep up with a friend who has a 12.8 second srt4.. lol

 

This may be a stupid question but do they make blow off vavles for superchargers?????

 

What can I do other then supercharge pulley exhaust and cold air to get more horsepower?? And without having to upgrade internal engine components??

 

Can someone please help me upgrade my mini!! I want more horsepower.. I have cat back exhaust, cold air intake and supercharger pulley but I want more!!!. What else can I do without it costing me over 5 grand?? And if I do something do what else do I gotta do to support it?? Please help!!!!!!

 

Hey guys!! I'm sorta new at this and sorta mechanically challenged! Need some advice bout how to get more horsepower out of my mini without spending an arm and a leg!! I put a 15% reduction sc pulley, Borla cat back exhaust and cold air intake.. What else can I do to make this fun car more fun??

 

To help handle the power, get a new, larger rear sway bar.

 

I don't have the power to get that yet.. I'm askin what upgrades can I do to get more power?? Like injectors? Header? Head? Cam? If I get injectors do I need to upgrade anything else?? If I get header do I need to upgrade anything else?

 

You've done the cheap power mods already. The rest start getting pricey. The next step for power would be larger injectors and a tune. Go with at least 380 injectors unless you do plan on adding a cam or head down the road which then you want the 450cc injectors. The tune will be able to scale even the larger injectors for your current mods and give you room for more fuel flow with later mods. A good dyno tune will add about 15hp and dramatically improve the driveability of the car.

 

Just go straight to a 450 Injector. Why wait on half mesures and spend money twice.
buy a header and a cam, it should put you around 210 to 220 wheel.
I guess the easiest thing to do is install a cam first.
I have had great results with my RMW parts.
And the most important thing about this entire post.
Do not try to save money and install parts yourself if you are not completely sure you can do it. Just pay someone to do it who knows how you will be much much much happier that everything just works vs having a catastrophe.

 

No BOV for SCs, as they never make excess boost like turbos.
Pulley is your best bet, as well as a custom tune. You can also go with larger injectors. Really depends what numbers you're looking for.

 

Do injectors, header and a ecu tune.

 

You have a 2nd gen with a SC pulley on it?

 

[QUOTE=yetti96;3623876]You have a 2nd gen with a SC pulley on it?[/QUOTE

He didnt say 2nd. Gen. did he ? Anyway I would suggest header,bigger injectors better cam and a tune to pull it all together. Also look in to dropping excess weight example: rear seat delete, lighter wheels etc. If you are still feeling froggy jump on a polished/ported head.

Umm the forum is 2nd Generation Minis > Modifications > Drivetrain (cooper s) so I THINK IT IS A FAIR QUESTION!

 

Unichip at one time could custom build a program for what ever mods you had done. Cold air, straight exhaust, underdrive pulley, cam.what ever.

 

Wrong car... It will never be fast. Buy a 5 lt Mustang or Camaro...

 

You could get around that 12.8 but why not track it than use it a drag car? Tracks are so much better IMO, especially with a MINI.

 

Unichip is really kind of old tech.
For remote tune contact WayMotorWorks or RMW.
They will both do a remote tune.
Or better yet try to get to either shop for a custom tune on a dyno..

 

What year and model MINI do you have?

What have you done so far for added power? From another post you mentioned you have 15% pulley, Borla exhaust, air intake, etc

What are you using your MCS for? Street only or any track? Driving Events?

What wheels and tires are you using now? More important that you might realize

For the 2003-2006 MCS for added power without internal changes:
Supercharger reduction pulley- from 15% to 19%, 15% is safest and generates less heat and stress on engine, can be used alone or with ECU tune.
ECU tune- can be done alone or with mods but MAP should be customized for your MINI and upgrades. RMW can do it or a shop can use Mynes software (see Way Motorworks) to custom tune.
Header with no cat- louder than stock, mild gain
Air filter and box- mild gain, louder SC noise
Larger Intercooler with larger hood scoup or air diverter vs Front mounted IC, some gains depending on how efficient IC is and how prone to heat soak it is.
Cat-back exhaust, mild gain, more noise, less weight, looks nice
Larger fuel injectors- only needed if you max out supercharger pulley or you want to burn lots of gas faster.
Larger throttlebody- not really helpful

Other mods-
Decrease weight always good- stock wheels are heavy, stock runflats are heavy.
Upgraded brake pads on stock rotors OK
Upgraded suspension, coilovers best and adjustable
Strut tower plates- offer protection from mushrooming of towers
Rear adjustable swaybar (3 hole 19mm is fine for most)
Rear lower control arms- to adjust rear negative camber
Front adjustable camber plates- provide tower protection and can adjust front camber which is only -0.5 degrees stock.
Grippy summer tires at least Max Performance

Have fun.

Not true, any MINI can benefit from an adjustable rear swaybar.

Sounds like you are posting the same question in many forums trying to get suggestions.

When possible you really want to limit your threads to the most appropriate forum.

In order to get the most out of your MINI you need a well thought out plan and a budget. Once done then get in touch with a MINI tuner shop and discuss your goals and budget.

It isn't a good strategy to go bolting on various parts when they may or may not meet your idea of power gains.

Added power without suspension upgrades is not a balanced approach.

Given the upgrades you have already, a good ECU tune should be the most cost efficient.

If you are not convinced that suspension upgrades are worth the effort then you should sign up for a driving school like EVO driving school.

Driving well is more than adding just power.

 

^^

Cheap more fun parts are 19mm rear bar and fixed camber plates for the front.

Next step in go fast parts are header and cam (I'd recommend RMW for best power gains), 450 injectors and a tune and your car will feel significantly quicker!!

 

Best post yet. I tell new motorcycle riders the same thing. They'll never out-ride the bike. The ones who can race them at the pinnacle of racing.

 

Threads merged and placed in the proper forum, hopefully all of this together will yield more context and assist with quality advice.

And from my experience with track days, long runs on the twistiest roads in the continental US; brake pads, rotors and fluid; then tighten the nut behind the wheel and probably set aside $1k for tires. And while many of the parts are bolt on, changes made in one area have an effect throughout, and you may make adjustments in one area to have them held futile by physical restrictions in other areas or be nullified by engine tuning.

Invite your buddy and his SRT-4 to an AutoX event, a bone stock non-S Cooper ought to be able to take him then, and you're only expense is perhaps a helmet rental if your drag strip doesn't require one.

 

Before doing upgrades of parts alone on any MINI I always recommend:

Driving school.

If you haven't done one then you don't know what you don't know.
Everyone thinks he's a good driver but few are as good as they think they are.

Why? Because even the stock base MINI has good performance when driven correctly for a given situation. The base MINI doesn't have gobs of power but handles well.

If you want gobs of power then buy another sporty car. If you want a good blend of handling and enough power then a Cooper S is a good place to start. The R53 MCS has a little less power but more instant throttle response due to the supercharger. The R56 MCS has more torque and as a result may have more torque steer and wheel spin if you aren't patient.

Better than adding power is to drop weight in the wheels and tires. 7" wide wheels will do the job in any diameter but the larger and wider wheels usually weigh more. Tires make a huge difference and are on the top of my list of things to mod on any MINI.

If you don't have to keep the runflats then there are great options for the MINI in tire sizes from 15" to 18". And even if you must have All Season tires there are some Ultra High Performance All Season tires that are very good on handling.
