Where did you get your #'s from ? as far as (catless turbo back) unless you are running BIG turbo and alot of boost that needs to be dumpped fast you are not gaining 20-25Hp however if you change the DP you will gain some, smal turbos needs back pressure to make HP too. in order to achive 280+WHP you need more than tune, CAI, and exhaust you will need head work, cams, bigger turbo, Dp and exhaust, BIGGER FMIC and of course TUNE.

Thank you Thumper.


There are many (JCW’s) putting out 250-260 WHP with nothing more than a tune, intercooler, intake and exhaust..... mine included.


And for the record, I spent 4K on my front Recaro seats and over 1K for my rear Recaro seats.

So yes, it can be done...



I hate to tell you but that link is over 4 years old... there’s been many breakthroughs in 4 years. My first tune from Jan back in ’08 was putting out 238WHP and 250WTQ, I assure you that was in the beginning. My JCW is putting out way more than my ’08 MCS ever did.

 

Can you make a video of your dash from 100-200 Km/h straight with 2 normal person inside.

 

Sure but why? My shift point is 7K and on the way back from MOTD, I cranked it up to 138mph and wasn’t even at 6K rpms. The car was still pulling.

At 60mph (100kph) the car will pull hard, hard enough that I don’t get embarrassed at the track any longer coming out of a turn on to the straightaway.

I´d like to see the time that takes to go from 100 to 200.

 

I understand.... give me a bit (I’m in WV at a UTV event this weekend) and next weekend is bike week at Myrtle Beach. As soon as I get a chance, I’ll make a video.

I won’t worry about trying to time it. You can watch the video timer and see how long it takes.

And Miguel, don’t misunderstand my statement about the work you’ve done. It’s WONDERFUL... VERY NICE, definitely a quality piece of work.
I’m definitely impressed.

I was just saying that “for the numbers you are trying to get”, you’re going through an awful lot of extra work when most of us are getting those numbers with a a tune, exhaust and CAI.

Miguel is saying 280 hp at the engine aka "crank", not wheel hp. 280 hp at the crank is (@ ~16% loss), 235 wheel hp. JCW's are putting out this power to the wheels.

At the same time, we must also consider Miguel's dyno and conditions he is running on. "A stock mini here will dyno arround 155 Kw, chiped i never saw more than 167 kw, yes 12kw more arround 6000 rpm.
So 280 hp ( in this dyno ) is a non realistic number."
155kw is about 208 hp
167kw is about 223hp

As we know outside of the US many dynos are rated by BHP, not WHP, so seeing that 208 bhp is (for purposes of consistency we will use 16% loss) is 175whp. That is just about what we see in the US, as my S put down 172 whp stock.
223bhp is about 187whp. So, based on this number, it shows they really aren't getting much out of their tunes. Seems like what we were offered back in the early days with the GIAC offerings for the R56, which gave us about 10 whp increase with an exhaust/intake.
So to Miguel, maybe take a look at what RMW and Alta are doing with tuning, and you'll see that stock S cars are putting down from 175whp stock to 200 whp after a tune, which is a solid 30 whp. (look here for dynos of people getting tunes https://www.northamericanmotoring.co...gen-dynos.html)

I was at 172whp stock, and put down 210whp with exhaust intake and tune. Tq went from 190 wtq stock to 235 wtq (about 243 HP, 273 TQ at the engine) with exhaust and intake and tune.
So, a solid 38 whp (45HP) gained, and 45 wtq (52 TQ) gained, stock turbo, stock fmic. So the limiting factor in your area seems to be ecu management, not hardware. THUS, whats good abotu this?? This means if you are able to access a Cobb Accessport or Dimsport for tuning or even get RMW or Alta to help tune your setup, you should see WAY more than 280 HP at the engine.
You did say your gas was pretty bad down there too? Remember this could play into it as well.

I don't think anyone is wrong here, but we are just being relative to different bases. All in all, with that setup in the US currently and the tuning we have here, we'd probably see 280 Wheel HP (about 325 hp at engine), instead of 280 hp at the engine. The work looks beautifully done, and I wish you the best in your journey and look forward to updates!

 

Not true, unfortunately. Turbos don't need any back pressure. The reason you use a larger diameter exhaust is not to dump boost, but to have a large pressure drop between either side of the turbo's exhaust vanes (or whatever they're called). Cat is a big restriction.

And I never said 280whp, I said 280hp which is 240whp

 

lol true I'm at 300hp on my jcw

 

once youre over 300 @ wheels.. i want to see your fueling system

 

explain your comment... my jcw is tune at EUROCHARGED PERFOMANCE and it is being built right. I have a full bolt on with my tune. The key is to not over stress the motor until you have build the motor. I say 250 to 270 is perfect for jcw without a built motor.
