[fozworth]

Ive got a MCS with JCW software and the following PERFORMANCE mods
GRS INTERCOOLER
GTT MANAFOLD
PLAYMINI S/S EXHUAST
380 INJECTORS
15% PULLY
FIDANZA FLYWHEEL AND FX 3OO KEVLAR CLUTCH
ALTA CAI
SF IC BOOTS
NGK #7 IRIDIUM COOL PLUGS
PALO UBER CARBON SCOOP
The thing is i went to take my car to have someone at a performance shop check if the clutch was slipping and thankfuly he recons its fine ,but he did say that he thought my car seemed no quicker than his wifes stock MCS and thought mine was no where near 200 bhp.Obviously im a little gutted and wounderd if im loosing boost or power from somewhere as the engine is like new with 15k on it and the charger is the same.He did say it ran very sweetly but not what he thought was quick and he drives 200bhp+ cars all the while.What do i check appart from the obvious like intercooler boot leaks (none) or slipping belt,its only done 600 miles and is a JCW one so should be to long in length.

Jamie take him with a £ound! of salt. you think about it their are to many high performance parts on your car to be the same as his wife's freekin 160bhp car he is talking cr@p.. i think you would no if your car was only 160bhp don't you mate..

sorry i missed you Jamie i have a big bikers rally on this week 3000+ to feed starts Thursday finishes sunday! need sleep lol... need rotrex super charger! hurry up Jan!

Jamie,

As above, I wouldn't put too much into it. However, you might be losing a great deal of HP using the JCW software. I have driven a JCW and wasn't real impressed with the performance. Might be worth looking at a better remap.

[Richard Crofts]

Unless you have a dramatic boost leak somewhere then he is talking ****. I don't have an IC but match you on a lot of other stuff and can safey say my car is faster than stock and even faster than a £1000 GTT 210 car

[GTT 280]

It may be possible that you have ill fitting snoot boots, or a leak else where.

A good idea is to get a boost gauge fitted. This will tell you for sure if there is a true lack of boost performance. It takes the reading after the intercooler and scharger so will highlight a problem anywhere is the "air system".

I'd personally get it checked out and get a gauge fitted. It would be a shame if your power was down for a basic reason.

Cheers,
K.

Hi,

try timing yourself from 0-60 may not be completely accurate but may give you an idea if things are not right.

[GTT 280]

This won't really provide you with the answers you are looking for. It will be easy to deviate by 0.5 of a second, which for a 210bhp car may be the area of fault you are trying to identify.

The best approach is to get the engine system checked out.

The parts you have listed seem to be quite mixed, so i guess this was either a DIY job or was fitted by a garage not 100% dedicated to MINI's ?

Could it be just a simple case of "let's bolt it all together and hope it performs well" ?

Cheers,
Karl.

I run the JCW software on my car and its certainly not limiting my performance.

All I can think that would cause you such issue is a boost leak. Check either side of the intercooler and make sure they arent leaking.

[Paul Webster]

Jamie dont forget why you took the original engine apart, can you rember my advice back then??

I have driven both (factory install JCW) and my car is MUCH more aggressive.

Sorry, but I am not a fan of the JCW tune and I think that it is lacking in regards to the mods that he is running. There is more power to be had with a proper tune.

So you have tried the same JCW car with JCW tune and aftermarket tune? When mine was evaluated it was decided it didnt need a tune as it was just in the limit of pinking. Car is very quick and pulls well through all the gears. I have pullies, manifold, decat, IC, CAI etc too.

i would second the JCW re map being poor i personally feel like the mth is a much better map as is takes into consideration the likes of all your mods and how the car is modified unlike the JCW map might be worthe a go?

I am running similar mods and am waiting for the MTH re map to get some power sorted out

[DaFlake]

The problem that I have with JCW is that it is designed within the limits of what is "allowed" by BMW/MINI. They are as independent as BMW/MINI will allow. It is also designed around very specific mods on the car. I use MTH myself and it is not bad (ok, I love it) but I have seen a few cars with proper tunings that are extremely aggressive and put mine to shame.

IMHO, there is still many HP's to be had with that setup that the JCW is not really adjusted for.

As for the tune, my buddy has switched to MTH and said that the car feels and responds better. We have not dyno'ed at all but he is much happier with the results and much more aggressive.

Guys, ECU maps are not plug and play. There is an art to tuning and making sure the A/F mixtures are right with what you have done. Just plugging something in doesn't make it good.

and

As mentioned above, it could very well be a leak.

Can someone explain why you are all raving on about map this and map that when Roland at GTT does'nt even bother mapping on most conversions, even up to 230 bhp. Am i missing something here Mines GTT230 and i run standard map. The only problem i seem to have is cold starting

Not everyone agrees with Roland's thoughts on that topic. I respect Roland and he does do great work (I even recommend him a lot), but I think that a good map will take the HP in the 230 higher. Roland has his opinion and I have mine. It is a grey area...

What are we really talking about with a remap? We are talking about letting the computer know what you have done to the car so that it can perform at optimum levels, a branch off the old days of setting the timing and A/F mixtures manually. Roland is pushing the MINI to the far end of the "window" and there is nothing wrong with that, but I would rather move the window to match what is in there and let the car settle in. This is my choice (and yours to go your route).

I simply mentioned that I think there is good ponies to gain by ditching the OEM (JCW and Stock) map. MTH was my first install (before pulley) and I can tell you that it made a HUGE difference in the car. I was pulling hard in all gears and I still am. Driving a JCW I find that the car feels flat and unresponsive. This was a factory install JCW (06).

[fozworth]

Thanks for all your input.I have checked my boots for leaksand seems they are fine,though they get snagged by the clamps due to the size of them .I used to have MTH soft ware but as i changed my engine and had to loose my big valve head and modded cam the software wasnt mapped correctly.I do have a few differnt brands fitted to my car but dont think this is the cause of the problem unless there inferior.Most of the parts ive gotton from a well respected mini tuner /developer in the USA and he,s happy that these all work well together appart from the exhuast which im sure is fine.Just because i dont choose to pay someone heeps of $$ to have their complete bhp package doesnt mean the whole deal a bodge up.
I think i will wait to get my replacment big valve head and modded cam and then get on the rollers.But wil look into a boost gauge as well .

Sounds like you have a good grasp on what you are trying to do. Who is your respectable tuner? Just curious as I always like to add people to my list.

[steve11]

Fozworth, Why are you concerned with what some person says? You should know if your car is going harder than when it was stock. Just sounds like a case of jealousy to me. People like that upset me. I wouldn't be too concerned, if the intercooler boots were leaking the car wouldn't be idling correctly & you would definitely notice.
