i was looking at the M7 website and sall the cosworth stage 2 tuning kit set up... how much power(hp) dose this kit put out?? i am just not happy with the power my car has now... thanks guys

 

Im curious too, Cosworth was huge with Ford so Im curious about how they are with MINI

 

Call: www.customminishop.com They are dealers for the Cosworth head, and SRTech AKA Steve, one of the owners has one installed .

 

I have the Cosworth head. It's OK.

But if the RMW head or the Wegner head were available to the MINI community back then, I'd have done them instead.

 

Only problem with the RMW head is you have nothing below 3000 RPMS.

 

have you seen the dyno plot?

it dosent seem to be lacking below 3000rpm to me.

Just an observation,
Jonathan

 

this is just plain wrong

there are numerous dynos showing this to be completely false... this was debunked months ago

here is a dyno over a JCW head which flows almost the same as a Cosworth
https://www.northamericanmotoring.co...postcount=1600

go to the very first post of that thread and you will see a stock head vs the RMW head

 

One problem with dynos, they are all different.

 

one thing about the same dyno..... the delta's are real

 

Yes that is true, thats why people need to go to the same dyno after new mods.

 

and THOSE dyno's went to the same dyno

 

Thats good . I didn't really look at them because I don't have the money for anyone's head right now . No need to get all worked up . I do need a tune though, are you set up for that yet? I know you where working on it .

 

So you have the one big valve head in the world that has life at low RPMS? Yes your better than stock but are you better than the cosworth at low RPMS? Thats all I was saying if you're building a race car go with the RMW head or if you live at high RPMS, But for the street I believe the cosworth is better. I wasn't trying to disrespect anys product.


Sorry next time I wont post.

 

LOL... there was a wink there... this is the problem with the net

yes... ready to go on tuning

 

no need for not posting.... but proper information is critical

mine outflows it from the time it lifts off the seat, if you want to "believe" the cosworth is better that is your perogative

I have the flow numbers on the heads, the JCW head beats the cosworth til .300 lift.. I hope that answers your questions.

 

No that was a tear smilie .

 

well how do you know the cosworth is better on the streets??? got a dyno plot to prove?

 

I'm not posting this to open up a can of worm's but you asked how a Cosworth drives on the streets, so here's my opinion of the Cosworth regular valve head on my car.
Well I've done 7,000 miles now with mine and it drives beautifully. When my GP was stock it was great, but now since Lucky Dog Garage finished off the install (which was well put together by Prestige Mini) with a Stahl Header and Custom Magnaflow, it can take off in 6th from 50mph no problem. I was recently at Watkins Glen with it and believe me it moves, it passed other cars nicely on the straights and caused a little stir amongst some of the other drivers. It has also held its own with a Acura NSX up to 140 mph when both decided to slow down. I don't know how it compares to other heads, you should probably try to test drive both if you can. The service manager at Prestige Mini has driven a couple of mini's with differant heads, you could maybe see what he thinks, as he has no loyalties to any particular aftermarket vendor as far as heads go.


When LDG 1st dynoed the car it had 194 whp, with the stock exhaust system.
After John did a tune it was at 208.33 whp, but Unfortunately on that day I had mostly regular unleaded gas in the tank after leaving the attendant to fill up my car in NJ while I got a coffee. Since then John has added the custom exhaust but has not done the dyno again yet. The exhaust made a nice differance.

 

I've never seen a cosworth car make more than 200 whp... the M7 car with all the crap they have on it made like 197 whp . Judging from the fact that I can pull from 35-40 MPH in 6th gear with little effort, i'd say the RMW head makes plenty of power down low. That being said, who the heck drives at 2000 RPM's on the street? Taking off from a stop light I rev the engine to 1500-1600 RPM's. In less than a second i'm at 6k if I give it full throttle . Driving normally on the street (shifting at 4k) I'm rarely below 3k rpm's. In fact, many times I take off from a dead stop in 2nd gear because first is simply far too short for this amount of power .

 

Whoa RustyBoy lets not be bad mouthing my car without any real knowledge of it’s capabilities.

As far as I know, you and I have never met, nor have you been in attendance at the many Dyno Day Shootouts I have attended, despite both of us living in SoCal.

The car often referred to as the M7 Cosworth car is my personal daily driver.

I have to thank M7 & Johnny’s Auto for all the support, advice, and hard work that went into this car.

Just to set the record straight this car has delivered WHP ratings of 210, 213 & 216 on it’s last three visits to Dyno Day Shootouts on three different types of Dynos.

The last time out at the SCMM club Dyno day shootout at Autowave in Huntington Beach, attended by about 20 MINIs that Jan helped setup for the club, the car ran 213 WHP & 168 ft-lb of torque. That was good enough to take the top WHP prize of the day. The attendees included 4 R56 models and one car with a RMW head.

At all three of the Dyno Day Shootouts this car recorded the highest WHP of all cars in attendance.

Now, I am not saying that your car or some other RMW equipped cars won’t out perform mine on the Dyno, but just saying that this car is no slouch in the performance department.

This car is basically un-tuned, only having an MTH non-tuner software flash, and Jan or any of the other tuners will be the first to tell you that leaves a lot of HP on the table, yet to be claimed with a good custom tune. The car also has a relatively low rev limiter set to 7250, so even more HP is possible for the taking. This car also has the Gen I Cosworth head and not the improved Gen II available today.

But this car is driven daily, and what really matters in the end is the grin factor when I step on the “Loud Pedal”, and in this case I really mean loud as this car also won the loudest exhaust award at the last Dyno Day Shootout at 118 db.

I am not advocating one head over the other, just trying to set the record straight on my personal car.

Looking forward to meeting you some day at a local event.

Bill

 

Was your Cosworth on display at Laguna Seca last Year when I took delivery of my GP, that was a nicely done mini.

 

Yes that was Bill's car you saw at Lguna. It was fresh from the paint and interior shop and drew good reviews. On behalf of Bill thanks for the kind words.
