I said its 'comparatively' easy to increase horsepower on a turbo engine as opposed to an na engine, FACT. anyone who works in engine development would know that. It's very hard in a na engine that's already running high revs/ compression ratio. The use of the phrase 'turn the boost up' is tongue in cheek it doesn't imply the necessary durability and component testing wouldn't have been done. In any case I'd be the first to listen and learn from a Ricardo employee in fact we need more people like him on PH and less like you. You say you know a lot about engines but you still point blank refuse to answer my question about how mclaren has achieved a power hike since the car was introduced. Any ideas you would like to put forward? Im 'asking and listening' now.

I think, actually, you said "turning the boost up" would take "5 mins in their tea break", and that they aren't really doing the customer a favour.

Exactly. If it was as simple as turning the boost up, every OEM would be doing these upgrades easy peasy. Its very easy to do this for a tuning company, as they're not going to give a crap about how the emissions are effected on the car, they just want more poweerrrrr.

If the manufactures could get away with it they would . See the focus rs500, extra 45 bhp only changed the intercooler and fuel pump, euro emission compliant and the job was contracted to mountune, a minnow really.

Except it wasn't 'just changing the intercooler and fuel pump' for RS500/MP350 spec.

In addition to those two items, downpipe and airbox, there was of course a revised engine calibration to suit. Which, as per the 625PS 12C calibration would have taken countless hours of development and sign-off to satisfy Ford that it could be offered as a fully dealership warranted upgrade to standard RS's, and as standard factory fit on the RS500.

It's just never that simple.

But now we're moving away from 'just turning the boost up' to changing a multitude of parts that will all have significant influence on the performance of the engine! And as Arun said, it will still have gone through all the Ford processes to make sure it passes the rules.

Standard procedure for a turbo car power increase tbh. The parts in question may have been marginal anyway, or they may not have been. Obviously the components on a focus rs, intercooler, etc are made to a price and have less 'spare capacity' than the conponents on the mclaren which are f1 quality nothing less. There has to be some justification that the customer has an engine with a list of mods over a standard RS to justify the premium over a standard RS. In fact reading through some RS literature it says most of the power came from a larger intercooler, whether that is true or not it doesn't really matter, ford sold every car they made, nice work if you can get it. The fact remains power increases on a turbo car can be achieved ins short space of time, relative to na engines, no doubt the mclaren will rise in power again next yr with different models.

I'm sure your remark was meant in a manner that wasn't intending to be derogatory, but Mountune are anything but a minnow.

[chudcy]

why do peole find the need to slate the efforts of a British company??

Embrace the innovation and technological advances....failings and all!!!
