EA888 rev limit

9.6:1 GTI

Funny not sure why JE lists 9.3:1 as stock ratio for GTI.

Me either.

That source also lists the compression of the R as 9.6:1 so

This thing really struggles to stay alive past 6K. It was designed for fuel economy and low end grunt. I don't see a point of pushing it over 6.5K on a sunny day.

In stock form you're correct.

Walk away Jim. He’s further gone than Zrick.

Not really, they aren't much better modified. It is the nature of the engine design. These are not rev happy engines. I guess you can dump a ton of money into it trying to make it something that it wasn't designed to be it the first place.

I still don't see a real need for maximizing the rev limit in this platform with how tall the gearing is. It's kind of pointless.

What about the turbos that don’t really start making the beans until much higher in revs?

I agree. With the TPC20 I'm still gaining power when it hits redline at 7000 RPM.

Interesting, I continue making power until 7250 fuel cut off. I would say that is much better modified than stock.

Damn dude, do you enjoy being wrong all the time? Guess you never had a BT setup or know how to modify a car correctly.

 

[Diggs24]

LOL. I floor it at 6k in 3rd and it’ll still spin and light up the TC. Not making any power I guess.

Well of course you can make more power up top with a larger turbo at the expense of losing some of the low end response but you are still shifting around 7K. It isn't a rev happy engine because it was never designed to be.

The EQT Vortex turbo spools at 3200 RPM and is still making power at redline.
Best of both worlds.

I get that but again you are shifting at around 7K, the rev limit is right around there. After that you are at a point of diminishing returns trying to make this engine something that it is not.
