Default ANyone dyno an EJ207 w/ AVO380

What kind of power and spool time
supposed to be like a Garrett 2871r
Flow Rate---Compressor---Housing Exhaust Housing---Turbine Wheel
44lb/min --- 0.60 S --- AR AVO 3-4 --- 46.95mm
from AVOturboworld website "The AVO 380S ball-bearing turbo has been optimized specifically to work with 2.0-liter EJ20 motors. Part of the Edge Series family, this S-Type is our dual duty race and street turbo, designed for a blend of high response and devastating power. The absolute best bang for your buck thanks to an enormous research and development program. We would even go so far as suggesting that the Edge range of turbochargers will outperform any other turbo on the market.
Supplied world-wide for street and race applications, you will not find a turbocharger offering better performance."

Isn't that turbo super mega like a GT30-35 sized turbo? Must be terrible spool time if it is this large. Post some specs of the turbo and it would be easier to know. EJ207 is no different than any other 2.0L engine, so spool time will be identical to an EJ20 whatever engine. Might want to change your thread to something like Spool-up of AVO380 on a 2.0L engine and then in your thread can put EJ207 you own though it's not relevent.

I have. Its to small in my opinion. It comes on about like the stock turbo with minimal increase in power. Consider that its only rated 40hp more then the factory turbo. For the cost outlay, The gains are just not enough. 44lb a minute with a T 2 small turbine holds this guy back to 380 Crank hp.

What turbo is bb, that would be a 400 crank hp with decent spool

A good question would be "what's a turbo with stock like spool that will make 350whp on an EJ207?".

Best thing you could do to retain the stock twinscroll setup you have is have your vf36/37 overhauled with a 20g compressor wheel... or wait for AVO, ATP, or Tomei to come out with their twin scroll direct boltons in 2010(I hope)

Unless you have a EJ207 with a single scroll some other set up on it... in which case you could always go with the Tomei ARMS. It is a great spooling 400whp capable turbo on the EJ207

Thats the problem.. Its a twin scroll. Not many options.

Fast spool and 400hp is simple.. 3071 on the 2.0.

clark would you say a ATP 3071 or a Dom 2.5 xtr? for a 2.1? or even go to a 3076?

I'll be saving my pennies for that twinscroll stock location 3071. Or the rumored twinscroll Tomei ARMS that DS1 was talking about.

So the AVCS on the EJ207 doesn't help spool at all?

By the way I have a V7 ej207 single scroll setup. I'm only using the vf30 til I find a decent turbo. My evoIII 16G got destroyed by a bad flex uppipe or I would be using that. I'm not looking for any crazy power. Just something that spools close to the 16g I had that can utilise the higher redline of the ej207 with a little more than 400 crank. I am running a aquamist 2D system on 50/50 water/meth

It does. I've seen an EJ207 spool 500 rpm quicker than an EJ205 with the same turbo and I've also seen them spool at the same time depending on dyno and tune. In general the EJ207 is considered to be a much more capable engine, but as always it comes down to the tune.

Saabaruba is just one of those internet benchracers that spouts off about subjects unkown to him to appear "smart".

I have one on a EJ255/EJ257 2.5 litre in an outback.

The AVO380 is in fact a Garrett 2871R. Look in the powerbraggin section and search Cobb tuned 2005 outback XT.

I put down 350whp/373wtq on Cobb's Mustang Dyno with a LEGACY TMIC on E85.

Would have been 375/430 with a front mount. Coming next summer.

Great turbo in my opinion and should last with the BB cartridge.

Also if you ever have to rebuild all you have to do is purchase a new 2871 center section for around 6-800 and you bolt on your housing and your good to go.

Here is a good video of Tim Bailey Dynoing a 09 STI with the AVO380.

imo its one of the worst turbo choices you can make. You can find half a dozen options that cost less, make tq faster, and make more power. I dont know if AVO changes their turbine wheel/turbine housing size off the garretts for which they are based, but when compared to comparably sized turbos they almost never seem to measure up to their counterpart's performance.

For the money you can get a 2.5xtr and would be better off.

I dont think it is the worst, IMHO. Especially if you want to stay LGT or 08/09 WRX fitment.
Fits in stock location and if tuned correctly on good fuel they perform well.

Show me some graphs of a 2.5rxt on LGT TMIC and E85 and we can discuss.

Fuel, Intercooler, Dyno, and tuner make a big difference.

As far as cost, its a garrett BB cartridge, ANY turbo with this center section is going to be expensive. The 2.5r or xtr are all 1600-1700

I actually paid 700 cash and 200 subaru bucks for mine and here are the numbers.
Most people are not comparing apples to apples PERIOD.

Pump Gas is NOT a good comparison, too many times you can get CRAP Gas and it not put out the results.
I am a perfect example of that. I purchased 93 shell and there is NO WAY it was 93, even the tuner said that.

E85 is a much more fair comparison because the fuel is WAY MORE CONSISTANT.

I saw your posts in my thread on the LGT forum, you really, like I said, have to be comparing alot of things, which many are not.


LGT/08 09 WRX TMIC, MUSTANG DYNO, E85

So, 300 whp on 92 and 350 on e85?

I'm having a hard time seeing the deal on a 2k turbo that does what a vf 39 does?

Turbo is not 2k, its 1800. , Even a 20g is that much if LGT/08 wrx fitment, or like I said any turbo with Garrett center section is going to be expensive. The 2.5r/xtr is 1600-1700

Easily out perform a VF39 if you compare apples to apples. READ PREVIOUS POST.

WASNT 92 OCTANE READ previous post. It was 93 from shell that even the tuner at Cobb thought was not 93. Could have been 87,89,91,92,93 for all we know. The GAS WAS CRAP.

SMALL LEGACY TMIC

Previous post shows STI with AVO380 turbo, STI style TMIC putting down 375/440 on E85.

With a LARGER INTERCOOLER LIKE THE STI STYLE OR A FMIC MINE WOULD HAVE DONE SIMILAR.

I think you need to do some research, and at least read before you post.

Can a vf39 do that?

Sure you can go bigger, but the AVO380 is VERY compariable, with Supporting mods, to similar sized turbos like the 44lb 20g.

And.... it is a QUALITY GARRETT cartridge as well. The 2871r cartridge alone, from garret is 600-900 bucks.

sorry man you an tell me I don't read or don't understand all you want. The turbo sucks IMO. If you are happy with it, that's all that matters for you.

So this sucks......



Your smoking Crack!

The guy with the AVO380 in your graph has a ton of POWER/Torque left on the table.

And by the way, the 09 WRX doesnt have a VF39, read your post above.

theres nothing left on the table. Its all right there.

its running 4 more pounds of boost at 6.5k to get that bump of 16 horsepower after being down a solid 20whp through the majority of the rev range below 4.5. It makes less power with more boost than a stock vf52 until 5.5k with a window of less than 1k of revs of power benefit.

The thing sucks.

I think the general assumption that the 380 doesn't do that much better than the V52 is because the 380 is mostly used with a TMIC, which is a bottleneck as you can see by the three charts above. If you did a direct comparison between the V52 and any number of well-known large turbo's, but ran them through a standard location TMIC (stock, avo, or perrin), you'd find that even 55lb/min turbochargers only perform "slightly" better than a VF52.
And then when other turbochargers are compared to the VF52, because of the lack of stock location options, many of those other turbo's are being run on a FMIC or a STI TMIC configuration - which removes the stock location TMIC bottleneck.

I wish I had E85.

You are correct on the TMIC thing. A VF52 might flow 38-39 lbs/min on the verge of destruction. An AVO380 will do 42 all day long, that is about 30 whp right there, assuming appropriate supporting mods.

What point are you trying to argue? The potential it has with fmic? Or the fact it has lgt/08 fitment? Eitherway it doesn't make sense. If you switch to fmic lgt fitment doesn't matter and a Dom 2.5 xtr or numerous other turbos cost less and work better. If you want to stay lgt fitment for the tmic, which I will conceed chokes it, then there are other options, like the vf52, which work better.

it is rumored that both ATP and Tomei are working on them.

the evidence is only an email sent to me from ATP saying that they are indeed working on TS gt30 and gt35's for subarus.

another member had a similar email from Tomei claiming the same.
