And if your lucky, he will let you touch his turbo conversion. mmmmmmm, nice!

Pete

what sort of work can u do to coopers?

[Cooooooperslad]

Ok apologies to roland for pointing the finger there, just assumed it was due to the GTT package after seeing ANT FR's and Aberdeen Al's posts.

At the moment there are many pros and cons that I need to weigh up between the two companies to make a decision on who to use.

Lohen Use Alta parts (I favour these over GTT just because they are a larger company and probably have more RnD than GTT)

Lohen are £100ish cheaper

Lohen are 40 miles each way closer than GTT

But...

Lohen only use a 15% pulley, I'm really after 17% after hearing how much better they are than 17%

Lohen dont correct the bypass valve unlike GTT (easy bhp for the money it seems with no implications)

Lohen remap the car (really not a fan of these bluefin remaps, I've read on here that all minis are different and a remap should be unique. Bluefin is applying one generative map.

I'd suggest you phone each tuner direct and discuss your requirements and concerns.

Alta are no bigger than GTT. They operate a one garage enterprise in USA...Just the same as GTT run a one garage enterprise over here. The R&D for them is the same perhaps even less than Rolands work. Roland does less variety of parts....but have a think...maybe thats cos he spends more time R&Ding those than Alta do so they have time to diversify?!

Alta stuff is good but on some stuff GTT are better IMO. I run Alta gear as its is a little cheaper as a rule but theres a reason for that

I know several folks with GTT and Alta car none have major issues and I'd not hesitate to use either.

My suggestion is get GTT stuff and have it fitted by 1320autos and get the Rolling road before and after...they are good chaps...plus reasonably local. lohen are good too but they don't have a rolling road. Go for what you can afford and build the package up in time...Its what I did and it gives time for you to notic ethe improvemrents or problems as they happen

Crikey Rigsy just seen your car exterior and set-up...we could almost be twins! I'll have to keep a lookout for you around Rainham and the Medway towns when i'm at the other halfs!

I'm really not keen on the idea of the bypass valve being "modified" and for what its worth id rather miss out on a few bhp and keep it standard.

I've been looking at lohens packages, I'm not keen on the idea of a remap really as I've heard some companys will risk the engines realiability just to gain a few bhp. For example making it lean in high revs to gain bhp when the original map is designed to richen the mixture to prevent pinking.

This made me think of just going to lohen with my own package design, the kit from GTT would have cost me near on £1k and will include bits im not keen on!

Was thinking of going to lohen asking for a 17% reduced pulley and shorter belt and iridium spark plugs. This leaves me alot of dollar for any other performance mods?

What kind of power could i expect to see from the above combination? (currently 163bhp)

What implications does the 17% reduced pulley have on the engine and realibilty / driveability of the car?

Thanks everyone and please correct my views if any are wrong, I'm a real worry guts when it comes to upgrading engine parts with aftermarket components.

lol my god don't cancel you will feel the Roland wrath!...

[Richard Crofts]

Oh here we go again

>>>>Wanders off till things calm down

[Cooooooperslad]

Im thinking as im the in the same county as richard he should take me for a test drive in his car so i can feel and hear what it sounds like, i know he has milly stuff too but still!

I think I'm going to stick with GTT now, sorry about sounding anal its just from looking and reading stuff and from odd comments ive obvisouly built up a false picture of GTT, main reason is probably just to me being a worry guts on this department!

Hey I know exactly how you feel, you just want to be right about this decision, my friend and I spent ages mulling it over, we ended up going down to GTT and staying the night down there in the Hotel recommended by Roland, both cars were down the next day. We both had butterflies all day, but once we got back in the cars, my god it was fantastic!

So far so good, no problems whatsoever, just an excellent job all round...

[Cooooooperslad]

Thanks for advice, had a good chat to roland tonight and thanks to that and you guys on here my mind is now at rest!

Looking forward to saturday, expect a review and a few pics

Whoa whoa whoa!!!!!, I never said it was because of my GTT220 conversion i was getting the yo yo effect. i'm not that sily, i'd never liable any firm on a public forum, even if it was true. I merely stated that i had noticed the Yo Yo effect since it had been doen, could be coincidental could be due to extra power as remember if your engine has weaknesses then uping the power will magnify them even more, so could haveb been there before. or culd have just started the day after i got home, whatever. Theres enough peole on here who have had the GTT220 done without even a whisper of a problem. In gact i don't think Al ever commented in his review abotut Yo Yo effect etc until recently.

But i am pretty confident that when i pop down to Dorset ( god i hate that place....lol) to see Roland and let him have a look, he will sort it out some how as he seems to be true to his word ( plus i am twice the size of Roland so he better sort it GGGrrrrrrrr!!!!!).

I will continue driving mine for now until i get down to Rolands on my return from Le Mans and guess what i'll probably spend another £500. Also this Yo You effec, its not kangarooing all over the place, its a gentle pulse when going slowly through the rev range, but definately there, but cane it and i feel nought.

Also bear in mind something else, if you are really reallly worried about tuning your car, then maybe you are best advised not to. As no matter how good any tuner is, how much they guarantee thir work, how many happy customers there have been in the past, whenver you take the car to be tuned you run the risk of problems, whether it be a £1000 GTT220 conversion or the £40,000 engine conversion AMD used to do for the Audi TT. There is always a risk, that something could go wrong. That is the idea of tuning, you up the power beyond what it was initally designed to be. And yes all the packages are tested, ie Roland does thousands of miles testing Lohen doo the same and so i am sure do many others. but sum it up with BMW spent millions testing the normal car, they used race drivers, they used wind tunnels they used computers and they used specialist tracks. But millions of pounds on, the car still breaks down. So i sum up with nothing is infalable, be it GTT , be it Lohen, Be it BMW themselves. Shiit happens andthats that. Minis Break

So do yourself a favour, go get the conversion done now whilst you can still Drive your car properly on the roads, cos give it a year or so and Big brother will stop it alll. or worse still you may have kids then theres no chance of doing it.

Oh and yeah mine was broke again, i have just spent the last 3 hours out the front, remving my driveshaft to change the inner boot on it and change the front discs and pads and then to sort the wonky bonnet once and for alll. And i am sure there will be a problem next week.

Oh and just one other thing, saturday night i absoloutely killed a saphire cossie, even the cossie driver pulled up later on to say WOW, thats quick, has it got a TT engine in it. I know, even i had to think twice, was'nt till the following day that my bruv worked out that the cossie drivr must have seen the GTT badge on the back and wrongly assumed TT.

Right essay over, go get it done

I'll keep an eye out for you :-)

.....The split CV gaiter spuing grease out everywhere ion Ants car s a classic example of faults we spotted on a car that dealers couldnt see . This is all included in the service we give . btw I may be getting on a little but did white collar boxing for 5 years gggggggggrrrrrrr, no Bruce Lee but I can handle myself. too busy designing GTT parts now.!
BMW/Mini are way from perfect, there are hundreds of threads going back to 2002! on stumble/yo-yo/surge etc with thousands of posts on it. We do not have a wonder cure for it ,we can only ensure everything on the car is as it should be.
Best Regards Roland GTT

[Cooooooperslad]

Well at least with the GTT210 (stealth package) i can keep using my cherished warranty if I do get any problems in the future
