Rolling Road - A Warning...
Discussion
Finally got my S2 back today after a few weeks away having a full service and paintwork sorted. Took it to another garage this morning to get setup and tuning done on the rolling road, after three runs and various adjustments we got 152.5. All was well until we started to hear a knocking/tapping noise, after close inspection it looks like a big end bearing has gone!!!! 
I did explain to the guys at the rolling road that I didn't want them to push the engine too hard, they took it to 6000 rpm...was this too high?
I am really p*ssed off, as the service has already cost me loads, and now it looks like another huge bill, and I don't think I have any comeback on the garage
YOU HAVE BEEN WARNED!

I think the red line is nominally around 6500 although I know people who take them beyond that. A rolling road setup involves full throttle through the rec range while you have much less cooling than normal, so if it's going to fail I guess there's a fair chance it will happen here. Doesn't sound to me as if they did anything particularly wrong and I don't think it's fair to blame them.
What a b1tch 
Bad luck mate.
Still, with the engine out just think how nice and shiny you can make the chassis
What do you reckon, rebuild or replacement engine ?
The Peugeot dealer which serviced our company cars would not undertake an MOT without either a recent cam belt change or a signed disclaimer absolving them of any liability for damage caused during full throttle tests (I guess this was for the emissions).
I'm a little surprised that RR places don't coat themselves in Teflon and make punters sign similar disclaimers.

My local rolling road always insists on signing a disclaimer, seems sensible to me .. after all teh rolling road operator doesn't know anything about the history of the engine, and rollers are unnaturally harsh environments. If it's gonna go it's gonna go on the rollers i think.
As said above .. take the opportunity to get something meaty in there now

Sorry to hear about that Better it went on the RR than with you in it. hope it's not going to be too much. My S used to red line around 6500 and I never had any problems taking it up to 6000, that's what the rev limiter is for. Sound like bad luck. Anyhow, just imagine what it will be like when you get it back and rebuilt.

I sent my engine to Specialised and they rebuilt it plus alloy timing gear, and unleaded heads.
This is better than buy a second hand unit that could have gone round the globe in aTransit.
This way you keep you original engine.
Their website listsall the options.
By the way the engine has now done 7000 miles since the rebuild and runs sweetly

But if you get a rebuilt engine you know it will be good, where as a replacement may have done well over 100K miles and be really shot, you'll only find out once you've put it in. Depends on the money really.
Very True, but when I was looking a year or so ago I could pick up a 2.9 around here from a donor granada for around £100.. (therefore know the mileage etc)

Thanks for all the support everyone, I am still waiting to find out the full extent of the damage, it looks like I may get away with just new big end bearings and an oil pump, the garage doesn't think anything else has been affected as it was caught early, although knowing my luck that may change next week
As long as I am back on the road for the meet in August!

My experience after 10 seasons racing? If you're ever going to blow an engine, it will be on the rolling road....
A competent tuner can set your engine up to give plenty of power by static tuning - the reward of finding those last couple of BHP on a roller was never worth the risk, unless you have an unlimited budget.
If you do have a big-end run, always thouroughly check the conrod and crankshaft with a micrometer before fitting new shells. It is very easy for the rod or shaft to go a few thou "oval" when the bearing lets go, and any new bearing will just knacker immediatly.

Just looked at Specialised Engines website, £900 for a standard recon 2.9 cologne!!!
Might aswell spend the money on a cosworth engine instead, is there a lot of work involved in getting it to fit?
I believe there is a lot of work, mostly in chassis mods etc. I believe it is not cost effective compared with buying a V8S. However, if your engine is blown then it may be worth it. This has been discussed before and you may find more by doing a search.
