[Closed] Borg Warner Efr Series Turbos

6Boob's are steam pipe brudda cuz.

As nice as FullRace items are, 6boob leads the way in collectors. Total sex.

not a chance.

6boost are amazing value for money, but if money is not so much of a worry the Full race ones would be my pick

[CaBS]

Unfortunately there are very few people around with the time/money to buy both and test them back to back on the same car and dyno. Until there is I guess we'll never know. I've seen both up close off a car before and they're very schmick. I'm curious of the effects the 6boost oval entry into the turbo flange has on a dyno chart. Apparently it increases exhaust speed giving better response but you'd expect it to lessen the flow in the top end?

[Beer Baron]

Now your making me want to sell my 8374. Any chance of seeing a dyno sheet from it? I know the numbers are probably top secret but even if you got rid of the numbers so we could get an idea of the curve.

yep there will be graphs I'm sure. we have agreed to provide the graphs to Borg Warner and Full Race and I'm sure they will want to share them. I don't know if the scale will be intact but I don't see why not. A certain power figure at just 1 point in time one 1 dyno doesn't really give the game away....

[Beer Baron]

Sounds awesome so far- not sure if you are joking about needing a bigger turbo though haha. Have you already maxed it out, and thats the motivation for saying that - or is it just because it spools better than you anticipated so figure a bit more lag for a bit more power would be acceptable?

This turbo is advertised as being able to ~95lb/min of air - if thats accurate, this has the potential to be a 1000hp vehicle... call me conservative, but that might be just about enough for a track car

yes serious about considering a bigger turbo. but we are not nearly finished with this one yet. like TheKeeper said we have not really stretched the legs on this one yet and the thought was pretty much like you said. it's response was so much better than expected that we'd be willing to sacrifice some of that for even more top end. but we'll have to see how much top end it has yet... if it makes a power number that is in kw at the wheels and starts with a 6 then we'll probably be satisfied.

the biggest thing the 9180 response has done for me is make me even more excited about the twin 6258s. they sit between a single 8374 and a 9180 in terms of flow (88lb/min combined). my thinking now is they'll probably be at least as responsive as -5s (maybe even -7s/GTSS?) and should outperform -10s up top. to early to stake my life on such predictions yet but it no longer seems impossible.

[Beer Baron]

Yeah I don't have anything really bad to say about 6boost manifolds. they are a great product. I have recommended them to friends of mine as far back as 5 years ago (or more). I can't say I've tested the same turbo back to back on the same car with a full race vs a 6boost. maybe one day. but I have looked carefully at both. They are both great products but I personally feel the full race is a little more advanced. they are so nicely finished too.

[Lithium]

No doubt some of the excellent spool and power you are getting with your turbo combo will have to be attributed to the manifolds, etc. The final product is effectively the sum of the parts used, it may not give the same result with an RPS Exhaust, XS Power exhaust manifold, reground cams and an old Microtech.

[Full-Race Geoff]

well anyone who reckoned the 9180 might be too big was way off...it's way more responsive than the -10s it replaced. getting the car set-up on the dyno at part throttle the thing is coming onto boost in the 3,000-4,000rpm range! my memory is hazy so don't quote me but off the top of my head at 4,000rpm it made 60kw more than the -10s

promising start - we think once you get more time with this turbokit the last thing youll worry about is pulling it off for another

Great news Richard. We knew you'd like the performance. We've seen in person that it's not hype, but ultimately want the guys in the trenches to show the rest of the community just how impressive these turbos are...thanks for the props, we do our best to make a product you'll never have to replace.

^^^^^ +1

agreed - after we finished the twin turbo EFR6258 skyline in the US i started to reconsider my personal cars' turbo setup. My car is LHD so its much more difficult to fit the twins, however I consider the boost response and linearity of the twin 6258 powerband as phenomenal, so I am particularly eager to hear your impressions compared to all the twins youve run over the years. we have a steady supply of the smaller EFR's from borg warner so if i went twins i could potentially put my car back together quickly...

seriously though, don't comment too much on Full race gear till you've seen it in the flesh. it's hard to capture properly in pics just how nice it is.

thanks for the vote of confidence, that means a lot coming from a seasoned pro such as yourself. Everyone on our team at Full-Race works *hard* to put out a top-shelf product .. anybody that claims to top us in quality or design better have their act together because we do and its not easy!

I would suggest something around 280 10.5mm if it's a track car. the thing is lots of the jap cams are a bit too big on duration and too small on lift to enable them to be bolt in cams.

totally agree with you - 280 x 10.5 or 280 x 11.5 is a great cam. I personally prefer to have solid boost response by ~3500-3700rpm so for my driving style and 2.6L displacement the 8374 is preferred. For anyone with an Rb30 and an aggressive trans like you guys have the 9180 is clearly the monster.

going by the results I've heard of the 67mm S400SX turbos doing - the compressor wheel is probably capable of pretty serious things, all comes down to how much exhaust gas the 80mm turbine can do. I'm picking that if the cam specs thrown around are at all relevant to this setup, its capable of quite happily cracking 600kw on a hubdyno running E85.

we recently tested a 1.9L honda on the BW S400SX 67mm, which as you mention uses a similar design compressor wheel to the EFR 9180 but with the 83mm inconel turbine wheel for max exhaust flow and power, designed primarily as a drag racing 67mm not so much focused on spoolup/response. on a 1.9L honda engine, 31psi boost and E85 race fuel we saw 950hp on a dynapack hubdyno. does not spool nearly as well as the efr of course

not a chance.

yeah it's definitely true that results are often the sum of their parts. this car with the 9180 (no real secret I'm talking about the Advan/Hi-Octane RGM R34) is a maximum effort car so has the best gear where possible. nicely built RB30/26, ARC intercooler, hypertune plenum, full race manifold, twin turbo-smart gates, EFR 9180, beautifully made piping, hollinger, dry sump, autronic ecu and CDI etc etc. so if ever a 9180 is going to be pushed it will be on a car like this.

we have very high hopes.

Which model?

[Lithium]

That is just awesome, can't wait to hear results... This is going to be the EFRs best chance to prove themselves, I gave up waiting for them to emerge but still hope to see success

[bigmikespec]

So what is the dealio with these turbos, antilag and warranty?!

Why did they ditch the twins?

[Lithium]

Sounds like it was a good idea by that initial report - when is tuning likely to be completed?

A decent single twin scroll turbo is the main thing that has been missing from that car's setup which has managed to have it not holding a special place in my "Man that this is so cool I wish I had one just like it" list

[Sub Boy32]

Why did they ditch the twins?

More power and quicker spool up? also less pipe work.

Sounds like the plot to a cheesy American fighting movie! Hahaha!

Hahahaha, giving away my childhood inspirations there

Look I'm not going to get into a pissing contest as I own neither and hardly care what people opt to spend their money on, yet here is what I base my comment on:

One looks hand crafted, the other looks machine made and tidied up with a die grinder. Fact is, 6b are hand made and FR are machine made, cant change that and it is printed in plain text on the FR site. Such is supply and demand.

I will agree with all you kiddies that the FR is definitely the better looking product on the outside and I would certainly be happy to own one.

And yes 10 years and trip to club med based on two dangerous drive events, so be careful out there guys. As necessary as the law is, those upholding it dont always base their career choice on morals.

I think you may want to re-read that post, because if you wrote it correctly it means you really have NO IDEA what you're talking about. If, somehow you got the names confused.... you're forgiven, we all make mistakes.
