Let's not talk about getting panties in a knot. These "tjooner" wars are getting stale and most of them are just making themselves look bad.

@FT_86_SM_GP I thought we were over it now, why create more drama?

Haha I could not resist/had a slip, the ex-VW driver inside me was missing the drama...


Apologies,

On that (drama) note, The Avo Kit does sounds wicked, and at 1m47s through that video....

Still wonder if having a turbo at the bottom of the road is such a good thing.. I explored both options for Top or bottom mount and ened up with the top version :

My concerns are
1. .. water and clean air
2. The distance for the air flow to the intake ..

any thoughts ?

Good questions Jacques.

1. A turbo generally runs more efficiently the hotter the exhaust side of the turbo (up to a point), hence turbo blankets having a dual function of both containing the heat inside a turbo for efficiency purposes as well as for stopping latent heat from escaping into the engine bay.

Having said this, the natural flow of air through the 86 engine bay is through the grill area and under the engine, right through where the turbo sits.

AVO have not had any issues with any of their BRZ/86 turbo kits and water and they have sold MANY kits.

2. The distance from the engine/exhaust ports to the turbo is possibly one of the (if not THE) shortest out of all the turbo kits, the piping on the intake side is thus slightly longer due to the turbo being closer to the exhaust.
AVO turbo kit being known for being extremely responsive partly due to the short distance between the exhaust and turbo.


The new WRX and Forester XT have the turbo kit in almost exactly the same position straight from the factory.

If I may add... It's also beneficial to have longer compressor-intake piping because, the more the compressed air volume, the lesser the lag plus there's more surface area to cool the compressed air, especially if a small turbo is used (faster spooling).

What takes longer to pump up, a big balloon or a small balloon?

Depends if it's you blowing

Your sister. So which takes longer?

What takes longer to deflate?... a big balloon or a small balloon?

I know it relates to the turbo subarus but the same basics will apply. Look at the piping length on a stock one - it's minimal and for a good reason - less lag.

SAV, this is different. Yes, fitting a bigger intercooler and extra piping will increase lag, and this is mostly due to piping losses. AVO setup in principle, does not increase piping length, they chose to rather have turbo closer to the exhaust than compressor closer to the intake.

In case of AVO setup
The distance between the exhaust manifold and turbo inlet is very small and considering how big is the diameter of the compressor outlet pipe, piping losses are negligible. Bigger volume, is really not a problem too. Its like having a bigger reservoir vs a smaller one or not having it at all. you will still have the same mass flowrate between the inlet manifold and the compressor discharge. I might also argue that you get better massflow rate with a slightly bigger reservoir because you get slightly cooler compressed air. Not to mention the ability to run turbo more efficiently with exhaust manifold mounted turbo.

Phew, either you type too fast, or I read too slow

I just took a good look under my bonnet to have a look at what really works well... (because it does!!)

Here ya are: It's a "very short" distance from manifold to turbo (12cm), a "very short" distance from turbo to intercooler (25cm), a "very short" distance from intercooler to intake (7cm), a small(ish) turbo, and not excessively thick pipes. Simple - QED. Minimal lag.

You can weight each aspect differently, but the reality is that you can't get better than everything being "very short" and no bigger than necessary.

Oh, I didn't say under which of my bonnets it was...
It's this one.

You can see how fast he reels them in from the reverse grid start, thanks to the power of the AVO Turbocharger kit!
