2.0 EFR 7670 Build

[PreciseD]

Hi Guys,

I am in the middle of a pretty large build and wanted to post what I plan on doing and the steps it takes to get there, along with the results. This is mainly about the engine build but I have some other goodies going on the car (RS4 Cluster, ECS Stage 4 BBK Fronts, ECS Stage 3 BBK on the rears (designing and making my own brackets) and some other custom parts) and I will post them once they are installed.

So far I have purchased everything but the Trans, Coilover Kit and 034 Control Arms as I am still deciding which one I want. I would also love to do the B7 S4 front end with RS4 hood but that's a future project.


P.S. If you have not checked out Redline Speed Worx they are doing some pretty crazy Stuff and have one of the fastest TTRS's around and work hand in hand with APR.

We are about to release a new Accusump turbo oiler that is more compact than the other one. It features a flow reducing fitting so that the oil is discharged at a better rate to be more efficient. We also have an oil filter canister cap that is nice way to plumb that Accusump. Part # 22-577

Solid build! And almost exactly what I have done. Only significant difference is I used the BW TS7064, the new IE V1 cams, and SEM intake. Right down to the tuning, your specs are extremely close to what is in my car now aside from what I mentioned.

Seeing that we aren't too far apart, let's plan to do a dyno session together when you are done, would be interesting to see the differences between your results and mine.

[PreciseD]

Sooooo what you mean to tell me is the turbo cooler I just bought last week is outdated? Smh

Yeah man that would be great. Did Jeff just do your tune? He said he got an A4 in the 700 HP range not too long ago.

Happy to see the EFR really starting to make its way into more and more builds. Looks Legit man good luck cant wait to see the numbers.

[PreciseD]

Thanks Good. I was really trying to be out of the box with this build and the guys at RSW showed me the sweet light that is EFR. I think to date only one other guy did a EFR 7670 build but never saw anything past a start up video. Plus it was a TT lol

[PreciseD]

If you have close to 700hp I can't wait to see what I'm going to get. Oh Just so you know I also stay in lower bucks some weekends.

The dyno will tell. Jeff estimated my output based on the % duty cycle of the 1200cc injectors and the volume of airflow recorded by the ProMaf.

[PreciseD]

Yeah I think he is going to use your file on my car for the initial break in period then I need to take the car up for the full blown tune. Oh and I just checked with RSW about the Cam because I wanted the IECVA1 not IEVCA2 since it wont support the HP range I am in. On another note I am glad to see the EFR's are going well above the HP limits that BW said.

[DaSkorpion]

OP if I may ask, how much is RSW charging to do this project. You can PM me if you do not wish to post...reason I'm asking is I might be going a similar route in a few months. Thanks!

[PreciseD]

They use standard labor rates per Bentley and I believe they are @95 an hour. After looking around this shop is AMAZING and if you get the chance to check out their new facility "its so clean you can eat off the floor".

Got some pics of some parts

Didn't think the rs4 dash gauges worked with b6's?

[PreciseD]

Yeah they will work. Once I get it installed and all the glitches worked out I will do a write up including a link to the guy that is doing it.

Now I have to wet my nose here, no disrespect(!), but noway. 700bhp on a 56lb turbo? Not even with methanol as fuel lol

If Jeff told you high 400's at 25psi/pump gas, thats gonna be BHP. I could definatly imagine 470-480bhp at 25psi/pump gas, just like Hansi's did 450-460bhp at 24psi on pump gas.

I would love to be proven wrong though Please post a log or a acceleration time in 3rd, I would love to compare some logs

[Turbavanttro]

No problem Bische, I hear you on that. I've always said its Jeff's estimate and I've also indicated how he came up with it (volume of air and injector duty). At this point I'm not really concerned about it and when I have a chance to get the car to a dyno, we will find out the real deal as far as whp.

[PreciseD]

Also on a side note the EFRs have outperformed the specs from BW. Guys are getting 750 or so from the 7670.

Will be very interesting to see your dyno

I would love to see that dyno sheet.

[PreciseD]

Google my friend. 583 awhp on an EVO. I would say that's pretty close to 750 at the crank.

Also I did my research and spoke with Full Race and BW to tell them my specs and goals and that's why I went with the EFR 7670 per their suggestion.

Yes google is my friend and I have consulted him many times regarding EFR's and their performance, but I am calling BS on 583awhp with a 7064

Look at the compressor map, a really efficient high octane running engine could hit 750bhp with about 65-68lbs of air, that wouldnt plot on the flow map - not even inside the picture lol

[AudiA4_20T]

Could be on a Dynojet

[PreciseD]

Sorry I didn't know you are the expert on Borg Warner and the EFR line up.

[Turbavanttro]

As I said in a previous thread about the EFR, I didn't choose it with a goal of achieving peak horsepower. I chose it to hopefully see a nice wide power range and power under the curve that is a lot better (hopefully) than similar sized alternatives.

I am happy enough to just let the dyno speak for itself. I mean really, who cares. Peak HP is over rated!

[Turbavanttro]

Let's keep the thread on topic. Any updates>

[MMMB00ST_A4]

Sorry I didn't know you are the expert on Borg Warner and the EFR line up.

Bische is the expert on MOST things regarding our cars actually, haha. He could tune your car as well as Jeff will.

[MMMB00ST_A4]

On-topic post: I can't wait to see what the graph looks like for this setup. Very excited.

[PreciseD]

I am looking for reliable power as well and that is what the EFR turbos will deliver. I am not trying to get into a pissing match by any means so I will just focus on MY build and attempt to be in the power range that I want to be in. I am not building a Dyno whore. I will be building a car I can beat the ever living shit out of (which is how I treat all my cars).

[PreciseD]

The engine is still with IE. They are doing the final assembly. Since I went with Custom JE pistons they had to wait for them to be built. I really hope that IE will deliver the intake manifold sooner than the projected End of July delivery date. I also am thinking that the car will be going under the knife in about 2 weeks or so. I will keep you guys updated. The guys at RSW are also going to be doing a in depth write up like they have done with other high end builds.

Not in the least. We basically came out with a smaller version. It is the same exact design and function as the one you bought it is just smaller. The biggest complaint we got about the turbo oiler is the size of it because people want to keep them in small spaces.

Ok that is very good to know. I like the size of it now as it will offer more than enough cooling to my EFR. With my setup would you recommend the 1 or 2 quart Accumulator? I plan on driving this thing pretty hard and would hate to lose suction in hard cornering or acceleration.

[PreciseD]

Hey Bische sorry. I wasn't trying to be a dick but I have done a lot of research into my build and so I was a bit defensive. In regards to the compressor map they are underrated or at least what I heard from my communication with the vendor.

Well deserved apology as Bishe is deff an authority on these turbos, not to mention many other things such as ME7 tuning....check out his build and notice he isn't even claiming / aiming for 750 BHP on that setup even though it may very well be in its wheel house.

Anything above 500 on these motors is most likely a trail queen / drag weekend warrior and not a DD which you will want to abuse on a daily basis.

PS I can't wait for Turbavanttro's numbers

[vinny.dtw]

Sounds like a exciting build. Glad to see more EFR turbos making into our cars.

Ditto what Bische said on the power output. But in the end, it's just a number.

If you planing on driving the car hard bigger is always better. The 1qt will only give you about 15 seconds of oiling in a high G situation as opposed to the 2qt is closer to 30-45 seconds.

It is no problem, I understand. Im not a peak power dyno queen freak either, rather the opposite actually - I changed out my BT 1.8t for a VR6 just for this reason. I wanted more torque and area under the curve, as I want to build a potent DD street car with a very useable power curve.

I didnt make the comments to bash or offend anyone, I am a fan of your build aswell as Brians. Im very curious of the outcome of your build, it is a very potent reciepe youve got there. I hope to yours both gets finished and share some data(I am a data freak though) for comparation.

Though I believe we are confusing two turbos here, I am talking about the 7064 which Brian have, and you talk about the 7670 yes? 583whp on a 7670 is possible just being concerned about compressor flow. But that is pushing it.

Thanks for the kind words guys, I really appriciate it

[PreciseD]

Well I went home for lunch and the UPS fairy brought me this.





Thanks to ECS for the great pricing and fast shipping on my Cupra R Lip and USP Center Grill.

assuming 'cost vs benefit' is something that doesn't appeal to you by any means.
