Didn't realize that, haven't spoken with him since I joined Uncle Sam's band of wayward boys in 2010.

 

So I got my Full Race 7163 kit yesterday. It actually came with a lot more than I expected. High boost wga (so I'll try this first rather than jumping to Turbosmart), FR stiff BOV (I plan to simply block it off), and a bunch of other accessories.

First thing that worries me is the wga. That and I'm putting this on a 4g64, not 63, so I'm unsure of the downpipe/oil pan clearance. I hadn't even thought about that until the kit showed up... 😕

 

WG shouldnt be a problem as on the full race kit it hits the gearbox and since your application will sit higher that shouldnt be a problem. DP is a potential problem, it all depends on how close to the pan it has been positioned originally..

 

How does the downpipe look? I haven't fitted my setup yet, and still don't have the dp material so I'm curious as to how the bends look.

Fingers crossed the pipe fits for you!

 

Any updates on this? Spring is here

 

Chad had 2 Evo 8s with RB-X and same general setup last week(10 days ago), one on 7163 and other on Blouch GT30( maybe 3276?),
We asked on FB for results, he said Monday he would post.

As In the past when CBRD announces new project/solution, no results are posted nor any comments detailing results and conditions under which they are achieved.
So back to zero data on 7163 to bolster confidence in choosing it.

 

So I felt like this was the tread to post it as a warning to everyone considering a BW turbo.

This is a customer car with an EFR 9180 with a 1.05 AR hotside. This was at 7200rpm @ 38 psi on a Subaru which has the VE of a Ford flathead. According to matchbot it is NOT overspinning.













While I can say turbos do blow up, the problem is that BW's apparently policy is to force a customer to wait for 2-3 months before they decide if they're going to approve your turbo for warranty. Your other option, and this was more of on Full Race's side would sell me a new supercore and exhaust housing at cost and give me a refund once it was approved. Quite frankly, this is absolutely unacceptable. Even with smaller vendors like Comp they don't treat you like a complete pile of garbage.

It blows my mind that the two options are drop another $1500 on a turbo and hope that Borg Warner decides to warranty your paperweight so you get a refund, or wait for 2-3 months until they decide if you're going to have to spend more money or not.
Needless to say, my customer is PISSED and is never going to use a Borg Warner product again. I knew these 9180's could be overspun and grenade but this wasn't. I'm probably pulling the 9174 off my personal car because I don't really want to have it blow up and then be out cash. To be honest, the EFR's make the worst power per mm but do have great transient response, that's about it.

 

I wonder what went first, the shaft or the wheel. Do you have data logs showing it wasn't overspun? I also wonder if EGT plays a factor in the turbine wheels failing. Having an rpm limit implies that they can only take so much heat as well. I'm sure the rpm limit is established with the wheel at a certain temperature. If its 150* hotter, I'm sure that lower the rpm tolerance.


I can understand your customer being mad, 2-3 months to determine a warranty is really ridiculous. As far as what Full Race is offering, that sounds quite above and beyond on their end.

 

Just throwing this out there but do you think there might be other factors that contributed to its failure? There are a lot of time attack cars using these same turbos with great results. I feel bad for your customer and shame on BW for taking so long to acknowledge warranty issues.

 

Eek, I just don't like the look of a cast compressor considering the heat right next to it and rpms involved. Is that standard for turbos of this size or just something to keep costs down?

 

Black E had an interesting comment somewhere that made perfect sense in relation to the size of the turbine wheel. Basically, the larger size of the wheel on the 9180 made it more susceptible to breakage, compared to the 9174 or even the 8374. I think it's still a bad omen no matter how you look at it and it sucks. I hope my 8374 stays together after seeing this carnage.

 

You can plug in the information to matchbot. 38psi isn't overspinning it and I've confirmed it with Cam @ Camtuning.

I have no idea what part of it went off first. What I can say is, even turbonetics doesn't have such a dog**** policy on RMA's.

 

So you didn't actually measure turbine speed. I'm not placing blame here, but I would not run any of these EFR turbos without an actual turbine speed sensor/gauge or some way to log turbine speed. Calculators are great, but the numbers you get out are only as good as the numbers you put in.

 

Right, and if you have something like a boost leak, 38psi doesn't tell you much. Wheel speed does.

 

And that's why I'm definitely getting the wheel speed sensor setup for my EFR...
