I am looking to get a new cam fitted to my s i already have the GTT 230 conversion with throttle body and header,i cant decide weather to go to west tuning and have them to supply, fit,re-map and dyno it or go with GTT to supply & fit then use chip and dyno it myself the hope being to get to 240 bhp,the other question is i currently have the standard cat back exhaust is it going to let me get to 240? or is it on the limit already?

any opinions on which way to go!!

[uae mini]

Is your head ported and polished already?
Since you had the conversion done at GTT I'd say go with them as the cam will be upto the standard of the conversion itself...

Which ever way you go would definitely be getting more horses.. by how much is THE question.

i too am looking for a power hike.currently have the 215 bhp WEST-TUNING package.

RAY WEST uses the SCHRICK cam (best you can get so far ).i have asked GTT about their own cam ,but it is a SECRET spec.(so no help there).

i have done around 8000 miles in my modded mini ,and no problems at all.

if you found GTT a good enough company to tune your car,them stick to them.

i want a flowed head/cam and header/re route pipe ,so it looks like i am off to GTT.

HOPE THAT HELPS.

Hi Guys, we also stock the Shrick cam,not only can we fit this with our GTT Adjustable Cam Sprocket at the same time at no additional labour charge,but if you have a GTT conversion already we dont charge to re-map for additional GTT products added !!!!
(first 12 mths )
GTT cam is almost identical to the Shrick spec but is ground onto OE cam rather than a new billet,the Shrick costs a little more because of this. I have 4 MCS Shricks coming in end of next week. Best Regards Roland GT Tuning

Thanks for the reply people!

I have taken all this in and i think that the GTT conversion i have already is great and so are the products ,the only thing is that i don't believe a guy in Germany can do a re-map that is exactly right for the car and the mods that have been carried out,where as west tuning do the re-map themselves(so i have been told) and can put the car on the rollers to see whether the map is OK or not and can also adjust accordingly, all in one day. If i don't go with them i had just as well fit the cam myself as and chip it myself using my cabe and software!

I dont think you would get Ray at West Tuning to upgrade your GT Tuning tuned car anyway so go with GT Tuning....

[Rickys'S]

Yes Rasp you are probably right, I will stick to what I know, looks like another trip to Blandford then, will e-mail Roland tomorrow

You've hit the nail right on the head and for me this is the only downside I can find to GTTs generic maps.
Of course this is in my mind and technically it may not even be an issue if the way in which the MCS deals with stuff is 'adaptive' enough.
From a personal point of view , it would be nice to have the car mapped individually (whether its needed or not is another issue??).

Of course the flip side is that if a generic map is proven to be ok , the costs are much lower and the development base for ironing out problem is vast if many conversions are done.

Re : Cams , I would go GTT to keep the whole conversion from one tuning 'house'
Edited to add : And IMHO given the amount tuning you are doing (and money spent) , a good flowing exhaust I would suggest at this stage is mandatory to maximize your package. Or at the very least a GTT bypass pipe.

Why may I ask?

Business is business at the end of the day...

Ricky, I thought that you would know better than to stray from GTT eh? Get going back down to Blandford

Hi Guys, just a couple of things worth remembering with mapping. You can never simulate on a rolling road the various ever changing loads and intake temps etc. that you are going to get on the 'open road'. Secondly all this sticking an 02 sensor up the exhaust
(even the much better wide band) is next to hopeless. I have tried doing comparisons
of this method against a sensor mounted upstream of the cats,the readings are very different.
The only proper way to check the fuelling is under various loads /rpms on the real road with sensor mounted upstream of cats.

In a way Roland i completely agree with you,but i feel that it is a must that the car is tested in some way after the tune is carried out,an upstream sensor sounds very good but a little unpractical unless you can leave it on for a few days of driving,what I'm trying to get at is that at least with a 02 sensor up the pipe!! it would give a nearer idea of what is going on, and then we know whether Franz needs to adjust or not,do you think a trip to millway (rolling road) could be squeezed into a day as-well for the car to be run up and checked out!

Roland you are still running standard cat back @273BHP i believe,do you think that the exhaust is a restriction or not really?,i would like to think that 240 BHP can be achieved with standard cat back system,is it not the header and cat that does the work!

if i am splurting rubbish please say

It is also worth saying that from my point of view,Roland develops the best components their is available, when i was looking around i visited minispeed,west tuning,GTT and decided upon GTT because their package is the most complete I.E pulleys,cooler,header etc, the engineering is the best there is and at the time i wasn't worried about the map,its only now I'm looking at the map being the weak point because I'm worried about detonation and running with a new cam will only make it worse unless the map is right!

I thought that was blatantly obvious

[roland2003]

Hi Ricky,yes our car runs stock cat back but with GTT re route pipe that deletes one of the silencers. regards Roland GT Tuning

[RedUn]

i was informed that the std exhaust (both silencers no re-route pipe) is gud for 240bhp, i have no idea how accurate that is

Hi Roland,

I totally agree with your first sentence, but regarding the 02, do you not use an AFR meter?, which I know is a very expensive piece of equipment due to its extreme degree of calibration, but is much more accurate than a standard wideband lambda sensor which can be subject to calibration errors and production tolerances.

[roland2003]

Graham . The stock sensors (upstream& downstream) are 'narrow band'. Our equipment
uses a super accurate ' wide band' sensor mounted upstream of the cats, so readings are not altered by the cat. Connected to this we use a 'very expensive' on board digital wide band AFR meter .This is calibrated in free air each time its used. This equipment and the way its used is the only way to get an accurate 'real situation' view of the AFR's under all conditions. Regards Roland GtTuning
