I think maybe this is a bit harsh.

Sounds like he's calling out FP & Dave... at least that's the first people I thought of when I read it. If I remember correctly Dave, you have previously made slanted comments toward's Eric Hsu's tuning ability, and it appears that hasn't changed. I can only assume it's Eric's way of retaliating to your comments.

 

Well, I guess one would really have to be in-the-know to realize its a jab at someone right? Regardless, I agree with R/T in saying your comment is a bit harsh.

 

Chu,
I think it was more of a response from Hsu in regards to some comments Dave made here on Evom.

 

Actually truth be known and not one sided like you have it R/T, Eric started in as soon as Cosworth took over the sierra-sierra EVO, comments were made on his end on his BS blog before I even knew sierra had gone to Cosworth. You should get the facts straight before posting what happened.

all I know is you used to be best buddies...

 

Funny how SOME things change. I have an entire list/industry full of people who I had respect for at one point or another, you want the complete list? hahahaha

 

Sure.

 

To the OP and off all this other chatter. Don't pull the trigger on anything yet. Robert at FP has sent out a turbo to me, I will have it Monday. He is pretty confident it will stomp this EFR turbo that isn't attainable anyway. Let me run this sucker and see what it does, I have a feeling it's going to be very impressive and will probably be something I push and sell after the testing.

 

Is this new FP turbo gonna be a T3 turbo or stock frame??

I'm guessing T3, right?

 

Yes sir, T3. The one I am testing is actually a Tial T3 V-band housing because it's what I am running on my car, easy swap. It's also available in a standard T3 housing.

We are gonna call it the EFReater.

 

I'm interested how Scott and Robert plan to get a TiAL wheel implemented into their turbochargers. I see that being one of THE largest differences between these EFR's and everything else. With such a HUGE reduction in MOI, I have a hard time coming up with alternate ways to make up for using an inconel turbine wheel.

 

Anyone want to buy my 7670? (j/k haha) This could get interesting..

 

the 7670 EFR is clearly a great turbo and results will prove that as more customers receive them and get their cars running. The EFR (un)availability is far and away their biggest drawback, since the only way to get one is to patiently sit on a long waiting list.

However - BorgWarner's 7670 S200SX shares the same turbine wheel geometry, its just made out of inconel instead of gamma-ti. The compressor wheel flows about 59 lb/min and at under $900 its a pretty incredible value. have not seen a single failure, ever, from one of these turbos. Not one. I personally cant keep waiting for an EFR on my evo, so this is what im running

Here is a 2.0L comparison done by Mark Shead @ MADevelepments in the UK, showing Full-Race GTX3071R .63 a/r T3 kit (black line) vs Full-Race Twinscroll S200SX 7670 kit (red line)



leetEVO im interested to see what the EFReater does to your car... especially how it feels on the track. the combination of great blade aero (with optimally matched compressor:turbine ratios), twinscroll hot side, gamma-ti rotating assy and slick bearings its going to be hard to top imo

edit: I just saw someone suggest the EFR T3 to be used on the existing AMS T3 manifold-- thats an impossibility. the T3 EFR is internal WG only, not gonna fly on any existing T3 manifolds, just will not fit. Evo fitments with EFR will have to be twinscroll - or very creative (like the setup FFTEC did with a forward facing T3 EFR)

 

Geoff, leetEVO is not testing the turbo and the EFReater name is a joke, just for reference. I do believe we can match or better the curve that leetEVO's car has, as good as it is. I don't know how much of this thread you read but his car and mine are nearly identical. Cams are bigger in mine and the header/turbos are different. I put the numbers up my car made on the HTA86 and other than the area under 4400 rpm I killed it and I am fairly certain leetEVO's isn't road racing under 4400 rpm very often.

Don't get me wrong, I've tried twice to get my hands on the EFR's to test, both times they have been unavailable.

Next week is going to be interesting, my car is going to get a serious work out with all that's planned.

 

Geoff, this is a serious question. You said the 7670 from BW tested above is the same other than the Ti/Al wheel, correct? Why do you think the torque is so much more abrubt in the EFR graph than on the graph you posted from Mark? I am being serious and not looking to argue, this is pure curiosity.
