hi i maybe in the MTH header/400cell cat. do know if you can disable the post O2 sensor with programming?? with some other BMW (E46 M3, for instance) turning off the code for the post cat O2 sensor effectively gets rid of the engine check lights and other issues associated with aftermarket cat. i'd preferr long term hi-flow cat over something that is going to give out in 30000 miles.. it seems high flow cats just give out faster. (instead of swaping CATs after 30000mile could we Ignore the post O2 sensor?)

 

No need to disable anything as the EML light is not coming on with our manifold and special file.

ok thats great...:smile: how long do you expect the cat to last? :smile: is there a waranty on the cat?

 

This is one of the reasons that we use a special 400 cell cat. It will last and not melt after 10.000 km. It lasts as long as the standard cat on your car.

 

excellent.. do you have any pictures of the header?

 

Not 100% professional pics, but then again - nothing to be re-invented for a header design. It´s the inside that counts.

 

where is this header made? by who? price? HP and TQ gains? MIG or TIG welds? by the way it's very nice looking!

 

Header is made in Germany. I'll let Volker answer the rest of the questions, as I dont have my spec sheet here. Here is what I have readily available (aka not at home).




This kit is designed for the gasoline MINI vehicles (One/Cooper/Cooper S), and includes:

• MTH Sport Exhaust Manifold - All Stainless Steel, with a special high flow 400 cell catalytic converter.
• A special version of the tuner software.

From a stock car, you would expect about:
One / Cooper: 144+ BHP
Cooper S : 210+ BHP

 

That's remarkable (no pulley, intake, cat-back, etc)? Any dyno plots showing this gain of 47+ hp from simply a header and a chip?

 

Andy,

I'll get the dyno plot for you, but it might be a day or two. I have seen a plot of a 15% Pulley, Manifold, and Tuner map pulling off 235+bhp, and I'll see if I can get that one as well (since most people have a 15% or more).






[edit for spelling and typos]

 

That's even more remarkable. 72 hp from a pulley, chip, and header. I'm looking forward to seeing the dyno plots. Make sure they show the whp.

 

Just for clarification, where are you getting the base HP from? My information shows a standard 2005-2006 MCS has 168 BHP stock.

 

I didn't realize this only applied to the 168 bhp '05+ MCS. Are the numbers similar for the '163 bhp 02-'04 MCS?

 

thank you for the pictures.. the header and cat DOES look nice.. now the question is: what should i expect from my alta intake and miltek exhaust when i add your header and software? it would be most impressive if i could acheive 210hp/plus without going the traditional route of ruining my waranty.. no worring about belts, pullies, etc... thanks in advance! :smile:

 

hey, i noitced you are charging $1300 for the header and software.. what about the cable.. not included? i dont have the cable yet.:smile: also, how long does it take ship and then receive it at my door step..

 

What correction factor are you using to get these #'s? 235bhp? I would like to know how you arrive at such high #'s?

with no head, cam or pulley ? no porting, intake, or anything else? just a header and software.

Please show us the charts and correction factor used so we can compare apples to apples.

 

Let me see what I can put together for you guys. But please bare in mind, that we are running on 98+ fuel over here.

Also I think that what is written on a piece of paper is not what counts. It is how the car feels afterwards. So I think best is, to get one header over to Pat, find a customer who is willing to put his car on the dyno and do a little write up on his/hers impression. Should be a standard S and/or one with a 15% pulley. For this customer we would make a special price. Pat, what do you think?

 

I'm down with that. I'll even pay dyno time if they're here in Houston.

 

Attached a dyno sheet from an S with 15% pulley, header and tuner
file running on 100 Octane fuel (Shell Vmax).

Mmax = 259,2 NM
Pmax = 183,8 kw
max figures are measured acc. DIN70020

effective WHP = 157,7 kw
tolerance 14.8% = 181 kw at the clutch

Temp = 37 degrees Celsius
air pressure = 1001 hpa
correction factor for front wheel drive = 1.041 acc. DIN

 

157.7 kW = 215 whp

Any idea what the baseline was before adding the pulley, header, and chip? BTW, thank you for posting the dyno.

 

I cant make any promises, but I'll see what I can do.

 

Sounds "too good to be true." What do they use to get "effective whp?" Why does the dyno seem to show the car reaching ~190 kw? Is the plot showing 'simulated' crank power? How then is the 157.7 kw reverse-calculated? Units !

edit: figured it out: plot is of 'simulated' crank power somehow. Then, 157.7 is about .85 [14.8% loss] of the 183.3 that the plot shows at peak. So, dynos in Germany apply a correction factor twice? Weird.

double edit: 157.7 kw is ~211 whp according to an online calculator.

 

Interesting that M7 sells their Cosworth kit for almost $4700 and it comes with the special MTH yet that kit on American dyno's only puts out 200whp according to Peter.

Can someone please clarify this?

 

1 kw = 1,35962 PS so 157,7 kw = 214,41207 PS

 

I always remember the conversion since I had a VW 1.8T that was rated at 150 hp and 110 kW.
