i know its been posted before, ive been reading up on it somewhat, but im curious...ive got an 04 mcs jcw. if i got this kit, i know its capable of like 400hp at 16psi, whats the reasonable amount of boost i could use on my stock engine with the JCW kit? if i want to use all that boost, what all do i have to do? pistons and headers?

i dont know much about performance, but im interested in learning, and im still reading up on previous threads about this as well.

also, is there anyone running this kit? is there something else out there better/similar for cheaper? how about that "Fireballed!" company? i heard theyre supposed to be making different stage kits, i emailed them, i dont think its out yet though.

i just want my MINI to be redicioulous and be able to spank like cobras and alot of fast cars, and i just want people to think its stock, and then blow them out of the water, not knowing what i have under the bonnet

this is the kit im refering to: http://www.gnvmotorsports.com/catalo...ts_id=1048.com

 

Jan at Revolution Mini is coming out with his kits that include a Rotrex SC which can output 350+ WHP. Anything more on these cars and it becomes unstreetable unless you want to spend $1000s of dollars more on other parts to make it track ready for seriours racing.

If you want to spank cobras, porsches and such save yourself the headache and buy an EVO.

 

i dont want to sell my mini though lol

id prally be happy with 350 whp.

so this Rotrex thing is just a SC i replace the stock one with?

 

Yes, hence leaving the originality of the car in being an SC. I believe Jan will have different stages of this kit with lesser power for everyday driving and the more powerfull version for spirited racers.

If you want to spend your money wait a little and make sure you've seen/researched all the products and see which one works for you better as far as how you want to drive and what you can afford.

 

im deff. not ready to order anything for a while, im starting to research things now and look at all my different options.

how come more than ~350 WHP is enough for a street MINI, is it becuase its FWD?

 

If your JCW is stock right now, you'll probably be amazed how fast the MINI is once you see over 220wLb-Ft. IMO, much over 260wLb-Ft is getting close to too much on the street with normal summer street tires on the MINI. A MINI with more torque than that and the first 4 gears become varying levels of burnout! On the track, however, you can put down much more power due to the stickier tires.

ALTA's comment about "400hp at 16psi" is totally misleading marketing jargon. They're referring to a point on the turbo's compressor chart, which is probably a point the MINI will never operate the turbo.

Get ahold of TrickleX; he's put the most effort I know of anyone into the ALTA twincharge kit.

Cheers,

i was reading up on his big alta thread.

what about the minis on www.fireballed.com ? click Machines, and look at the different ones theyve built...some say 600 hp, etc...what do those have on them? their own custom kits?

how many hp do i have right now to the wheels with my stock jcw?

edit- thanks for the help so far guys

 

about 200whp depending on which version you got since the newer one puts out 210 whp.

 

Stock '04 JCW is about 178wHP and 162wLb-Ft on a Dynojet, as I recall.

Fireballed also does twincharge kits of their own variety, as does Helix13.

 

On our dyno, we typically see jcw cars getting in the mid 180whp range

 

This is incorrect. You're thinking 200PS and 210PS, the european rating for power at the crank. These equate to 197BHP and 207BHP. Please do not confuse the different units. There is an approximate 12% drivetrain frictional loss between the crank and the wheels on a rolling chassis dyno.

For the '05 and '06 JCW kits, rated at 210PS, this is correct. Earlier JCW cars has slightly less power.

 

thats what i thought.

id love 350 to the wheels

i just dont want to get into boaring out the pistons and all the internals and things like that.

im sorta interested in that one Supercharger kit that guy was talkin about...wonder what pricing would be on that...and what else would i have to replace/change as far as stock parts go?

is there anything on my engine that i can chagne now before getting into major mods like turbo or a different blower, that will get me more power for now?

 

Ok maybe this will help:

if you went over the 300+ whp with the same SC which is impossible unless you went to turbo you could use forged pistons but turbos run cooler to the engine.

With the Rotrex apparently you wouldn't neccesraily have either to change the pistons since it's running more efficient/cooler to the engine.

I would go with a bigger valve head/cam for more power but the thing is your JCW has a ported head already I believe and yu would need to replace that if you wanted bigger valvs, wouldn't make a financial sense.

 

ya ive got a lot to research before i make a purchase. but in the near future im deffinently interested in getting alot more power and making my MINI faster

 

the beauty of doing things " right " is that you can adjust your HP by you boost... you say "350 whp" but have you driven a mini with 250.... it does not take as much as you think to beat the cars you are wanting to... I think I was making 275 when I was taking last gen cobras with ease...

do not get caught up in the NUMBER... learn about how to make power with the mini.. what kinda power delivery and driving style you like... etc... then you can make a choice that you will like...

Ryephille is one of our best... and Trickle has done the TC and not sees that turbo only is better... as most of us who have made the jorney through the 250+ hp have all realized.

opinions are nice... I recommed listening to those who have done it... I personally feel 400 is very streetable... LOL... I like it and don't have any trouble... for some it's just too much... know YOUR limits...

it is far too much to put into one post... but the key is... how you drive... and therefore how the car would act... and moreover... how she acts at WOT.... LOL...


edit: there are a few other guys not with Turbo only too... Kalbone, AZ MCS, esmturbo... I think those are spelled right... but again.... these guys have not converted... and could prolly give you some good ideas of $ and time they spent...

 

from where you are now to make MORE power your looking at different tunning programs along with few more bolt ons. Therefore your looking at Header to go along with your catback/exhust.

Alta has the Hydra software that is new and Jan (Revolution Mini) has the Rotrex SC. With these additions you can be well over 250+ whp and that is very strong for a Mini. I'm running close to 215 now with my newly addedd mods and there was a huge difference when I went from under 200 whp to now somewhere around 215. I know that with proper tunning/Hydra software and other parts to tweak the torq to get the most out of the car I could be looking at somewhere close to the high 230s. Of course I'm hoping for more.

 

The problem with more HP and TQ is once you get used to it the Mini starts to feel slow and you want more.

Are you prepared to smoke at that crack pipe?

 

yes

Tuls: were u beating stock cobras or modded ones?

my friend has an 03 with all kinds of mods, and hes producing around 650 rwhp, more with nitrous...his car is fast...

 

650 rwhp.. hmmmmmmmm i think brian's widow will eat it for breakfast

tuls probably raced a stock one.. and even stockers are known to be F a s t..

 

Oi vei.......horsepower smorsepower....its all relavant to what you want. You want to beat these guys? Go to the drag strip and baseline your car. Having xxx number of horsepower doesnt mean diddly if you cant drive it or launch it or it delivers it's power in some rediculous curve. I am pretty familar with that year cobra and can tell you that car is in the 11 second bracket easily. You will be hard pressed to beat it in a MINI unless you sink more into the MINI then you paid for it & ONLY if you do it right, then you will have to learn how to drive it without spinning into oblivion.

I love my MINI no doubt, but again its not designed to make huge power easily, then to top it off, it isnt engineered to deliver that kind of power to the ground. Can it be done? anything can be done if you're willing to dedicate the amount of time and loot to it. Will it be just as easy as building up a civic? hell no....

As for Twin Charging...I would advise against it. Its just not a effieceint or well thoughtout design. There is a lot that can go wrong & the driveability is nothing like a heavy modded SC only setup. The benefit of a twincharge setup is that its fairly easy to do without really doing heavy modifications to the layout. It does work and will make power, its just not the best way to go about it.

As for me, I am still running the ALTA kit is some form of fashion, but to be honest the only parts I am using at the moment is the header(which I have had issues with) & the intake piping. I have since built out a new downpipe all the way back to the tips. I had clearance issues with the Alta dp hitting my front swaybar & the issues with that was enough for me to seriously break out the welder and goto town. The engine I have in the MINI is still 100% stock and although I dont advise it, I run 28psi everytime I got wot. Why you may ask? Well I am trying to get the pistons to fail. I have a 2nd engine waiting to go in that I personally built with CP pistons, arp rodbolts & head studs, & RMW's Jesus head with iconel exhaust valves. I am actually waiting to do the engine swap until I get my daily driver back from the bodyshop. I am going to run turbo only on this engine, but I may put it in the twincharge setup until I break the engine & new clutch in completely. That is just because I have the twincharge sorted and baselined and I will be able to focus on just the engine's performance without dealing with all the other stuff that comes along with the conversion to turbo only. The only other way I would do it, would be to convert to turbo only now and leave in the stock engine until I sort out the turbo only conversion.

 

Ay Caramba....Where to start?
Probably the best thing is to shoot me or one of the guys who has converted to turbo only a PM (Ryephile, Kalbone, esmturbo, or me). Public opinions are gonna be all over the map and there will be lots of advise from people who have not done this which is worth.....well.....let's just say not too much.

Conversion to turbo only is expensive, but in the long run will yield the highest hp numbers, but as has already been advised, what are your goals? What do yuo want to do with the car?

I still use mine as a daily so it isn't tuned to the last 10/10ths ability. Saying that there are plenty of 335i's out there that know to watch out for my car when the think they can "just jump around that little car and cut him off"

 

how well do you high hp cars get the power to the ground? is that true with the 1-4th = wheel spin?

I admire you guys for going the extra distance that most arnt willing to go, but at what cost!?!?!

 

what is brians widow? lol

 

Well said.
400 hp in a MINI is well beyond my skill.
Part of the problem is many don't know their limit.
I may be gutless but I will come home to the kids.
