Are this EWG units only, or IWG also? What a/r is being used? I would like to upgrade from my Iwg 8374 .92

 

will do

 

So anyone think a EFR 7163 would work good on a built 2.2 for Track/Road use?

Engine is being built and was looking into options for a 450-550 hp car.

 

Yes, do it and post results http://www.full-race.com/store/efr-t...anifold-1.html

 

7163 is awesome-



That is the CBRD RB-X kit with licp, downpipe, everything- along with dry breaks on the coolant lines-

Here is a pic from our annual summer open house this past saturday-

Borg Warner is proving to be excellent for us- and had a display on hand for our customers to take a look at their technology!

 

I can't seem to find this plot?

 

I have actually looked at this kit as a option, from the looks of what that BW turbo offers is very impressive. The V-band set-up makes everything much easier IMO.

My old turbo gave me 40k good miles, and still runs strong. i am hoping to do better with a newer tech turbo.

 

That's uhh....pretty.

 

From what I've heard, the margins are quite good on the EFRs.

Just saying...

Still love to pick up an externally gated EFR7163 in a thinwall housing and aluminum CHRA though.

 

I like their IWG setup... the WG canister might need a bit of work though..

 

But it's just a pic

Weeks/Months of talking about a new level of performance and posting pretty pics but sharing no results surely is for the Extreme Tuner thread?

A mate has an EFR7163 with .80 T4 divided hotside for his 2.3 which will be tuned on 98 (~US 93 Oct) in the next couple of months - tbh I've not been too comfortable with the turbo choice as there have been lots of hype about these turbos, people in this thread say they have tried them and like them but there has been no EVO results actually posted which makes it hard not to think that either they don't REALLY perform that well, or they haven't actually been tuned yet and there is no proof that they are really that good.

I'll update when this one is done regardless of the results - I'm completely impartial, if it works well I'll say it and if it's not the even more EFR than EFR then I'll say so as well.

 

Pardon me sir could you please point me to the documented testing results.
Enough of the pish posh.

 

EFR 7163 .80 Vband in/out vs GTX3576r on .63 TiAL housing. Both 100 oct.

Here is an interesting comparison. EFR7163 on a 2.5TFSI 5 cylinder in the TTRS on 100 octane and stock intake vs GTX3576r on a .63 A/R hotside from TiAL. They are different cars, but the setups are pretty much identical from the built engines, to same fueling, etc. We put the stock intake on the GTX car to make it apples to apples, though with a nice intake, it actually picked up 24whp above 5500. We put the same intake on the EFR car and picked up the same power, but we only had 1 intake/

Sure, dyno numbers right? We took both of these cars to the drag strip 1 hour off these tests and the best trap for the EFR car was 125.75 on the stock intake with the power as shown, and the best trap for the GTX3576r car was 125.80mph. Both full weight 3300lb cars without drivers in Vegas on a 4300 DA night. The APR GTX3576r car did have the +27 intake on for the drags that night, which explains the slightly but basically same power under the curve traps

Take home? Well, why would you put a GTX3576r in a .63 housing? I scratch my head at that too, but it wasn't our kit. Sure, a .82 would likely pick up 30-40whp up top, but it would likely drop another 300-400 rpm in spool. We are actually going to test this week on this concept, so I'll check back.

I posted a while back that a EFR 7163 could touch 600whp. That just isn't possible on my dyno. It is an honest 550whp/550wtq on kill mode( we do it on this same car 30psi tapered to 25psi) but shaft speeds hover right at 151k. Our dyno is pretty harsh, and I do think you could do 600whp on a DJ or maybe even a DP.

That said, it is going to touch 10s at ~130mph on a full weight Audi TTRS on 100, so that speaks a little bit to the potential of the little guy. And dynoqueen and trap speeds aside, the EFR is loads more fun as a DD. Very fast response, and off boost "max boost" is really night and day compared to the .63 GTX3576r setup.

 

Better quality, sorry<br/>
