Have you spoken to Josh yet? He's got all the info you need out of all the threads you've posted so far.

Lol, journal and waterless. Yeah right.

Higher rpm with the same front wheel sounds good I guess ,especially factoring e85 to the equation..

The 88mm is a +1500hp turbo, 9174 is a good street replacement though. I'm keen myself but no one is showing any turbo speed logs.

Hey guys, how's the speed sensor coming along?

ANDRA/CAM spec Cage done. Dry Sump pump done, Engine ready for shipping.

Hopefully people will start posting turbo speed, since it's absolutely crucial for these EFR's

Should be able to bang that out today!

What was the turbo speed at 30psi on the top end?

Who is doing your build?

That's what they all look like before going in though, I reckon it's better in the car than as a coffee table

Head Bottom End Dry Sump Pan

The car as whole starts moving? Compared to otherwise NA with no boost assistance? Responsive means "street able for such a high output car"? You mean driving around with no boost? Whole package with no expense spared means physics does not apply? While I find you absolutely hilarious in your claims, I'm beginning to come to a conclusion that you have ill constructed basis to your judgements.

It comes down to the reaction between ethanol and aluminum, which is why companies coat their products on the inside to specifically combat against the reaction.

You are at full boost by 4k?

Doesn't sound like you know what responsive is if it means spooling at 4k.

All I said that was it is an issue, and yes it can be controlled and mitigated with more costs than otherwise stated with EFR'S. I never said that over spinning is a mute point on non EFR's. When I first brought this up, everyone ignored it except lith. My point was that people need to know the limitations before hand and work with it accordingly for their application rather than blindingly thinking that it comes with no draw backs. At the end of the day, as others have mentioned, pick the application that suits your build knowing the entire list of pro and cons and that's that.

In the past, if the turbo stopped making power, that'd be where you'd have stopped as it would be out of its efficiency zone. The turbo speed didn't seem so crucial as you would have stopped prior to the limit or the limit is much higher and/or not catastrophic immediately. With the EFR's and the combination of E85, the rpm limit appears to be an issue.

EFRs can't be over spun apparently.

Bead blasting done.

Hope it works out for you. My last one was hit in exactly the same spot as yours and it was deemed as only good as a donor of my current build. Keen to the progress, more of these cars need to be saved.

Yo piggaz, what size is that down pipe?

Woops, *invalid. Sorry.

Oh, don't get me wrong. The more protection the better so I am saying your point ain't valid.

What about using a knock sensor and then have a map setup for knock correction to the ignition timing?
