They are not stock numbers. Those are with the downpipe, intercooler, intake, and 30% ethanol mix!

 

These numbers are al WHEEL HP and TQ. The runs with out the tunes were all impressive, but it's the intake, cattless DP and large IC that helped, also 30% E85. Also the GP has a higher compression ratio than a JCW and larger turbo than a typical S.
The only other thing I might do is a ported manifold and wait patiently for the JB4, from Terry. Meth, might not help me very much since I use E85/91 and live in a town were it's always 70F next to the beach.

 

It would be really interesting to see a dyno run with 93 but no ethanol and no JB for comparison. I'm interested to see how much the ethanol is helping the stock tune.

That would make a really interesting comparison, 93 and no JB to compare with what you already have dynoed ie 30% ETOH and no JB, vs 30% ETOH and JB at max.

 

So assuming you add the 15% drivetrain loss, you're running at about 280hp 310tq at the crank! Not bad.

What's next for you? w/m injection and you don't need to run 30% e85.. it would save ya some $ in the long run

 

A cooper s with a renntech tune, jcw turbo, downpipe will get you 240 on a cooper s. the renntech tune actually favors the cooper s more than the jcw. one is 900 dollars and the other is 300 i think the jb+ is

 

Wonder what the gains would have been with a regular S turbo?

I had the JB+ at 100%, but I'm rolling around with it removed for now.

 

Does the JB+ set off any codes and/or require any tuning or can you just hook it up and go? I've never messed with the chip-seems almost too good to be true. Is there any downside?

 

Nothing to do. Takes about 20 seconds to install.

I have a 2013 JCW CM and I started at 30%. Since it has been installed I am getting the P0171 "system too lean bank 1" Terry seems to think it might be something minimal but we are waiting for the Can Tool to arrive to assess the issue.

 

Did u follow the install directions?

 

Yes. I did everything the instructions said to do. It typically takes about a half hour of driving for the code to come on.

 

He's right

Also The JCW and GP are just about an exact replica engine wise.

 

Also I'm curios. can you elaborate on your 30% ethanol mix. I'm curious about two things, are you mixing ethanol and gas by your self? If so are you running a map switching device for the tune when you don't have access to the mixed fuel.

And what if any are your concerns with running ethanol through the High pressure fuel pump and fuel system. The GP should have the upgraded pump style, but I'm not sure they are ethanol friendly. Running high concentrate Ethanol through the fuel system should (unless I'm mistaken, which I could be) tear it to shreds.

 

thats why hes not running high concentrations of ethanol....hes only running a 30% mix.

typically its measured straight from the pump......if i recall the proportions correctly, its something on the order of 3Gallons of Ethanol to 9 Gallons of pump gas.

i cant imagine the engine being sensitive enought where its going to cause a problem if you are off by +/- 1 gallon on the mixture.....your average person should be able to manage that.

 

Yes it seems the JCW likes to throw this tuner style code. Turning the dial down may help but since it's a passive code a better solution (other than just ignoring the dash in light) is to simply leave the CT connected full time. It will remove passive codes that way.

 

Hats off to Terry Those are some INSANE numbers for a MINI, especially the torque. That is something I could only wish for on my Elise

 

I leave mine connected under the driver floor may. I have zero codes even with almost 250whp. Thanks to BurgerTunning, I never even got a check Engine when I installed my cattless downpipe.

Speaking of downpipes, you have "M3 downpipe" listed in your sig, what/where did you get that?

 

It's actually M cubed, but I couldn't type an Exponent. It's mine own company and I worked with a friend to build my own DP. He is a master welder and builds supercharger kits. I wanted a DP with perfect fitment and a third bung for a wideband Air/fuel. I'm making 50 of them
I have had nay DP's and exhaust kits and it rare to find one that has near perfect fitment.

Can someone explain why a S couldn't get the same numbers as a GP or even JCW? Don't they have the same engine? I know the JCW has a slightly larger turbo, but other than that, isn't it just factory tuning that is different?

 

Let us know when you have some ready for sale.

 

The JCW/GP has stronger pistons and block than the S. JCW also has lower CR.

 

There are many rumors about the difference of a JCW car and a regular S. But really the only differences
JCW 10.1 CR and 40mm turbo and a tune
S 10.5 and 37 turbo
GP2 10.5 CR and 40mm turbo and some advancements in cooling.

A normal S can make good power but the 37mm turbo is too small and just because it can make the same PSi as a JCW, it has to spin too fast and that creates HEAT = loss of Hp. He'll even the JCW and GP2 have tiny turbos.
As soon as BurgerTuning.com makes a JB4 programmer, I will get forged pistons and a 45mm hybrid Turbo. 300whp and 320whp should be a nice daily driver.

So would the e85/91 octane mix have any long term effects on a S model or any mini really? With that alone I could run the jb+ at 100%? Thanks.

 

I have a '13 JCW and am also getting the CEL. I can clear it with the CAN tool, but can't figure out how to actually read the code...
Any advice ?

Thanks
