AVO turbo kit for BRZ - initial build thread

[gmookher]

I like the level headed approach AVO is taking, no sense rushing to the market if you can not offer post sales support, on going tuning and prevent buyers remorse attrition from neglect.

they have been one of the few companies, that seems genuinely interested in data collection and refining a solution before bringing it to market, a la perrin. it makes sense to be late to the party if what you bring is truly the cake.
that said, mad props and respect to the pioneers who are first to market and putting them selves out in the front lines.

The best selling systems will be ones that are conservative, well tested and supported.
9 outta ten guys dont want a 10psi boosted, clutch eating, 300hp FRS, until its been out for a while. I want more power, but for now, i just want a little power boost, not alot.

those other 9 guys will however pony up for a more conservative 5psi setup properly packaged WITH a tune and airbox. So far visconti is closest to offering that solution, with perrin as a likely second, with SRT and VIVID as candidates if they were ECUtek shops. FA20club has potential too.

So far no one company has a end to end developed solution. its one companys header, another's turbo, anothers airbox. piece meal of a bunch of less than refined converged components

There is something to be learned from my experience with DINAN engineering with BMW, and its more than them being factory authorized ROM. Its the end to end work they sold me, from intake to tune to exhaust, its a turn key non show off make more power reliable solution. I love it.

Once the meat of gung ho types are burned thru with show off type 300+hp builds, and they start seeing failures; the 'masses' will seek the equivalent of VW GTI APR Stage 1, -a 40 whp boost- almost there...which is what DON/Visconti offers today. Then the next wave will be folks like myself who want a smallish turbo or supercharger. Nothing crazy, nothing to prove anything with. Stage 2.

AVO, as a manufacturer, not just a reseller, I hope you can develop the solutions we seek. Eager to see what you come up with.

Id love to have my frs at 300 whp, i wouldnt mind getting a new clutch if i had to in order to run 300whp as long as the engine is ok im good!

[gmookher]

exactly my point
I dont mind getting 300+ horsies under the hood either, but strategically, I rather not sign on to the 300+ club right away-no one knows what the 10,000 mile or 30,000 result of a 300+ hp FA20 is gonna be like

Me, I feel pretty confident a 5-7psi boost, yielding 250-275hp is the ticket for this car. I have other cars in my garage that make more horsepower; more is not always the answer.

I firmly believe, having owned a bunch of high performance NA and FI cars, that this application would benefit a supercharger more than a turbo, but thats juts my opinion. I want to get rid of this dullness below 4400 rpms...

well said, I would like SC solutions for drivability matters.
turbo kits don't kick in until around 5k rpm and that SUCKS!

Not sure where your getting that info from? Look at the torque dip on every turbo dyno so far. There is a mountain of more power below 5k. And you will only gain low end on a roots type blower. Enjoy that power below 5k as the turbo car will walk right past you after that.

You need to drive a car with a properly sized turbo for the powerband/application you have...

I had a 1.6 Miata with a GT2554R... 12psi@2800rpms gives you plenty of kick...

On a 2.0 like the FRS/BRZ, I could see a GT2560 being pretty nasty for throttle response and early boost at 5-6psi.

I don't give a crap if a turbo car passes me, to me it's all about the feel of the car. I owned a 370z which is basically a high reving torqueless car compared to my MK6 GTI. I truly enjoy my GTI much more because of the power delivery and I know a 370z would walk all over a my GTI any day.

back to the subject... ANY updates?

If you look at the HKS supercharger torque curve it still has a huge dip. So far I like the turbo curves better. I don't think spooling will be a big problem on a small turbo. Ever driven a MCS with the twin scroll turbo? There's no lag at all and it has awesome low end power.

@AVOturboworld, save us!! Get us back on track.... Any updates

But, the MK6 utalizes a turbo, which you said you hate because they don't kick in until 5k...Not trying to continue to go off topic, but just saying.

[gmookher]

yeah, controlling the rear end at the edge of grip is just more linear feeling on supercharged platforms, ymmv

[JoeBoxer]

I know a lot of OEM turbo applications are able to reach peak torque under 2k rpm is this something that would be possible on an aftermarket kit?

example: Audi A4
Horsepower: 211 @ 4300
Torque: 258 @ 1500 2.0L/121
I know its a different engine style but if we could get peak torque lower I think it would work well.

[AVOturboworld]

Technically, it's possible, but it means a really small turbocharger that will peak out quickly (note the 211hp is made at 4300rpm in example above).

Our turbocharger kits for the 2.5i Impreza's looked basically like this:



The dyno doesn't show the onset of boost, but road tuning shows the magic starting to happen at 1500rpm. Peak is reached relatively early at 2800rpm, and it plateau'd till 6400rpm, where the 2.5i's start getting in reach of their redline.

Now - this is not the 2.0-liter BRZ motor! It's just an example. The 12:1 compression, different combustion chamber design, and higher rev limit/available power band means different results and different setups. With the turbocharger up front and right off the exhaust manifold, though, it will probably respond quicker and may get to peak torque sooner.
