GTT certainly attends the the mechanics/engineering aspect first, applying a conservative and well formed map thereafter - the right way, and no lean mixes.

£850 to remove your head and look inside - WOW, nearly as funny as me paying the same amount for BMW to fit a £60 item and clean my carpets - STUNG on both ass cheeks!! grrrr. Now, where is that county court summons form.....

Well we don't know that yet and speaking to Roland the other day it seems detonation at WOT in 5th and 6th is a problem with tuned MINI's in general. He said he recommends not to use WOT in 5th and 6th with his conversions for this reason. He also recomended the use of an octane booster for track days too.

Only with our turbo conversion, which removes the SC completly can we utilize water entry (remove factory blanking plate) by No1 cylinder ... MUCH BETTER! The water then has to flow across all 4 cylinders equally and exit at the thermostat at No4 end of the head.

This design ****-up of BMW really niggles me. is there absolutely no way that the cooling could be modified for the Scharger versions? Seems like a last minute solution on their part. not good.

Do you have any hard figures as to how tollerant this 1st cylinder is to over heating? I mean, if i drive at 6,500 rpm for 10 minutes on the autobahn using 104 ron fuel, will the engine blow??? assuming an average air temp of 15 deg C....

I thought Roland did not recommend WOT driving in 5th or 6th when using normal unleaded (95 RON) but it was OK when using super unleaded (99 RON)?

...correct, but i did say 104RON fuel !!!!!!!!!!!!!!!!

(...and i can't use anything below 99RON anyway, well, not without considerably worry ))

True but I was referring to Root Gingers post, I should have used the quote button :-)

I never apply WOT in 5th or 6th

The Batmobile is loooking great

Is it WOT?? I use it in 5th and 6th....but then its short periods of time and I dont go out trying to see what my top speed is where you are defiantly asking to blow your engine. Too much stress for to long.....

I think it's WOT at high load in 5th and 6th. As I understand it even a short burst could be harmful but I'm sure Roland can confirm this.

No news from Roland yet on my car, but I know he's busy so I'm not too worried. I will give him a call tomorrow, when I get up, if I haven't heard anything.

OK so I've spoken to Roland.

The damage is just a finger sized hole in one of the valves. Piston and bores are OK. Phew!

So what am I doing? Well Roland gave me a few options but I have settled on a JCW210 head to replace the standard head. I was actually surprised it was standard as I always thought the Hartge conversion had a modified head. This gives me a bit of an upgrade for not too much outlay. I also have the option of JCW injectors.

Whilst there it was discovered that the Redstuff pads have worn very quickly and the discs need changing too so a set of GTT spiroslots are going on. It will be interesting to compare the standard pads and discs to these.

After this is done the mapping will be checked.

[Rigsey]

Sounds like you will soon have the batmobile back :-)

Looking forward to your GTT brake review as I think mine will need changing in the near future ...

Cool.

You however have a problem with the spiroslots......

......they look so damn good, you need to do the rears as well to make them match. Fortunatly, Rolands prices are so keen they are well worth doing......

Has all worked out ok for you then - Some routine work getting done at the same time as the repair. Every cloud has a silver lining!

Hopefully it'll be back with you soon
