from what they, as in APR, tested a stock gti at, it achieved 212hp. their stage 2 93 octane achieved 254hp. by my math thats a 42hp gain and torque of 70lbs. well within their claims. from the vast amount of research i have done these engines seem to be underrated from the factory. which in turn lead even more credence to apr's numbers for their actual testing of stock power levels. if that is true and the stock tsi motor is infact underrated and does infact produce numbers closer to 215-220hp then vw doesnt leave them self much wiggle room for the soon to be failure that you are talking about.

It's clear you don't understand how the OEM works. They don't use older engines just because they are stronger. They use them becasue they exist and new parts don't need to be made. When parts are in the part bins they can grap from here and there and make an engine for nothing.

"You might expect that the [2010 Golf] R and GTI would share an engine, only differing in tune, but you’d be mistaken. The GTI’s Audi-developed EA888 2.0-liter turbo four is not yet sturdy enough to handle the power and torque required for the Golf R, so the burlier model keeps the older, VW-developed EA113 engine..."

So the EA888 "isn't string enough" to handle 270 HP and 258 FT-LB of torque....

Okay...

But look at the Stage 2 and Stage 3 gains...

They greatly exceed the levels pointed out here:

harddrivin1le,

Stop posting magazine reviews. You know who writes those, don't you? People like you.

Show me documented Proof. If the magazines have documented proof from audi and vw then surely YOU have access to the same information.

I'm a mechanical engineer with 24 years of experience.

The bottom line is that the EA888, in its present form, is a weak engine - relative to the factory fortified EA113 engine.

Your Stage 1 tune is probably "okay" in that it produces very usable gains in output with only modest losses in longevity and durability.

But the Stage 2 and 3 mods push the EA888 way beyond its design limits.

Great. Prove it!

PROVE IT

Find me 1 Technical document that proves your theory.

Wikipedia and Magazine articles are not proof.

pointed out where.

also did you come up with the 50k mileage time frame of engine meltdown out of thin air. is that your professional opinion? or if one were to believe the wiki article what is the current lifespan of a well maintained stock 2.0l tsi? 200k? 300k? what is it? if its the latter and i have a stage 3 and by doing so i reduce my lifespan by a 2/3 then you mean i can get 200hp per liter and it could last around a 100k. sign me the hell up partner.

I highly doubt a mechanical engineer would put their credit on the line by citing Wikipedia and magazine articles. Bring VW proof to the table and then we'll talk.

But your sales pitches are. Right?

Car and Driver and Wikipedia are good enough for me.

I'm not going to waste my time searching out VW/Audi supplied engine details because people will just discount those, too.

Hmm...

Proving your point using factory supplied specifications is a waste of time.

Proving your point using magazine articles and Wiki is a productive use of time.

Gotcha.

Wikipedia is fine, as long as it has a link to the information. the only problem with wiki is that its not written well sometimes.

just sticking up for Wikipedia!

You are aware that APR is involved in motorsports, right?

If your choice of sources are good enough for you, your argument is not valid since it does not bring first party facts to the discussion.

I would love to see you in an argument in court and watch you get turned away so fast.
