power vs reliability

Featured Replies

I'm a big fan of the new vRS & the revo'ed version is awesomely quick & surprisingly driveable.

However, I've just been reading about the new Audi S3 which uses the same engine.

It develops 262bhp & 258lbs/ft but the VAG engineers have seen fit to change the intercooler, fit a larger turbo, stronger con rods, gudgeon pins & bearings, new pistons & even different cylinder head material to dissipate more heat!

That's quite a lot of work for a relatively small performance increase. It makes me wonder how the standard engine parts will cope with the effect of a remap, long term.

I'd be interested to hear your thoughts & experiences on post-remap reliability.

Any remap will compromise reliability as the tried and tested components are being run closer to or outside their designed tolerances. Whether this would be evident in the time you owned the car is another matter though - I suspect with the bulk of reputable remaps they wouldn't :D

Put two tonne on a one tonne trailer and yes it will move the two tonnes and may do so for a fair time, but one day some thing will give out on that trailer due to overload stress.

Your power train and chassis are no different to the trailers problem in coping with the extra load and stress.

VW themselves did a golf gti-r for the sema show in the states, they bolted on a bigger turbo and ran a quaife diff, 400bhp and 340ft/llbs.

If a car is remapped, then yes your increasing the potential wear factor, but are you driving it at or near the limit for a greater period of time?

Most remaps for the 2.0T fill in the gaps, as in increase performance at the low to mid-range and I think the standard box is rated at around the 340ft/lbs mark.

Driven properly, warmed up, cooled down, regular oil changes should see a remaped car into high mileages, there are plenty of remapped mk1 vRS's around Brisky that have passed the 100k mark without drama.

I think Fluffmeister has hit the nail on the head.............price versus perceived "quality": all a big sham!!!!!:thumbdwn:

... or they purposely engineered the engine so it can't be tuned much past the 200bhp mark stock.

Then they have already chosen the parts to make it go further, and 9 out of 10 cats that want 270ish BHP will buy the Audi rather than pay some cash to have these parts changed plus silly insurance prices.

Both are totally plausable and I'm not saying this is the case, but it is an option.

Never knowingly underengineered...

Expensive, but gives a warm, secure feeling :)

It had occured to me that they may be trying to justify the extra money, especially as they are being very up front about the mods.

It is interesting though that very little was done to the 1.8t until it reached

225bhp & even then it was only an intercooler.

Good to hear your views on a tasty conspiracy though!:thumbup:
