1.6L 2560r record attempt
#167
No, because I have yet to see anything that conclusively shows otherwise. The only threads I've seen on various forums shows at best slight spool improvement over a 2560, and then they break. I don't doubt the EFR will make way more horsepower, it's the spool that I'm questioning.

Edit to add: Which is why the EFR is magic. It spools like a 2560 but makes power like a 3071.

Just to be clear, in never said I had anything against the EFR, they are clearly a great turbo. But that doesn't mean they're for everyone or every build.

the EFR is a good option if you're running a built motor. On stock internals it seems to me that you're spending substantially more for extra top end power you can't use. From what I've seen you aren't gaining much if anything on the bottom end. Also don't forget that when comparing a GT2560R to an EFR6258, the EFR, if you use it to its full potential, could mean replacing your tranny and diff unless you already have a 6 speed and torsen. The reason I am using the GT2560, and wouldn't consider changing, is that it maxes out safely within the limits of my drive train. I would be interested to see as close to an apples/apples comparison of as possible of a GT2860RS to the EFR6258 I think that would be a more meaningful comparison.

This car is built. Anyone running an EFR is built.
Yes - running a much less potent turbo on a non-built car is probably a good idea if you don't want to blow up said car and if your goals are low power. For this specific reason people run the 2560 vs say a 3071 or 3582.
I mean c'mon, I'm really not TRYING to be mean to you here. You're just asking for it
#174
I didn't mean anything close to that, why would anyone compare a 2560 on a log to an EFR on a tubular twin scroll? Dann is using both turbos on the same manifold. What I mean is that on the same setup there will be very little difference in spool but the EFR will certainly make more top end

nice. congrats

I figured out why you irritate me: you jump into conversations where everyone is on the same page and well past basics, and start talking about 2+2.

Jim you also need to keep in mind that along with that 700rpm advantage in boost threshold, there is torque (which equals HP).
The EFR will always be 700rpm ahead of the garrett meaning that you make more torque across the entire low and mid range.
If that isnt a HUGE advantage nothing is.

Also Im putting an EFR on this setup in the near future and today I start work on putting an EFR on an MSM, which currently has a stock bottom end.
The turbo Im putting on it has a 12psi FORGE wastegate actuator.
Wonder if it will break the bottom end with that actuator..?

You know what 18psi, you need to grow up a little, I was responding to a specific post where a question was asked about something i said and being as clear as possible in order to avoid some jerk going off because I wasn't clear.

Sure you're trying to be mean, it wasn't me that started comparing the EFR to the 2560, I'm saying it's a silly comparison. All the spool of 2560 with the power of a 3071.... you keep using that comparison to bash Garrett turbos, why not try comparing th EFR to a more similar Garrett?

I'm not convinced you're going to see a 700 rpm advantage in spool. I know some have seen that but they haven't really been apples to apples comparisons. That's why I'm curious to see you're results, same motor, same manifold. I know this is going to go over like a lead balloon, but when FM tested the two turbos on very similar setups the EFR showed virtually no advantage in spool.
