Those will be possible upgrades, yes. We just need to test everything thoroughly as they come out, and will add in features as we can.

It's already been addressed by others (thanks Bob@drift-office!), but to clarify, the base map as we are calling it is a daily driver tune. If we were simply making it safe to run to the tuner, we'd have been done a long, long time ago. We are creating a safe, smooth, fun to drive tune that works with 91+ octane pump gas. The reason it's called a "base map" is that it's not a tune specific to your personal vehicle.

Seriously, we've put a lot of long, long hours on the road and on the dyno to get this right for everybody, and I think I can confidently say, you won't see that from any other kit on the market. This is a kit designed to have the fit, feel, and reliability of a factory upgrade, just as if Subaru had done it. Except better.

It doesn't mean you cannot upgrade to higher performance with this kit, it means we are getting the stage 1 right from day one.

As far as upgrades, what kind of turbos will bolt in to this setup?

Same issue here in Dubai UAE, will there be a tune for different octane ratings? We got standard rating of 95 and premium of 98 octane.

The JDM tune that runs up to 250whp, what octane fuel was that??

Also what is the intercooler's HP rating, for future mods reference??

Thanks

Hey Guys got a question from your press release.

http://www.avoturboworld.com/index.p...news&Itemid=31

Turbo Specifications:
AVO18/49 Turbocharger with 5-7psi actuator - compressor wheel size 49.2/56 | exhaust wheel size 50.5/68
This specially designed AVO18/49 turbocharger comes with a 5-7 psi actuator for precise boost control at lower psi levels, ensuring engine longevity. The turbocharger is rated for 380hp of flow, so there is certainly headroom available with it from the base stage 1 kit, which is doing 276hp on 92 octane.

You say that this is a a 5-7 psi actuator for precise boost control at lower psi levels.

With this in place how can we run higher boost once we change the MAP sensor so it can support more boost?(as I read this was the limiting factor early in this 57 page thread).

Emailed them about a possible meth kit a few weeks ago and they said they don't work with meth or e85.

At laaaast! Thank you, Lord!


some questions though:

1) how exactly the oil pump is driven by the camshaft? do we have to drill in the head severely or there is a technological window?

2) if I will be running 93 ( 98RON Euro ) fuel and a full 2,5" exhaust - would that lead the car run out of maps you will be providing along ( or did the final testing include full freeflow exhaust) ?

3) also interested in ECUTEK features provided ( launch, FF-shifting, etc )

4) have you discussed possibility running Speed Density - oriented flash? That would be a nice option for the guys wishing to leave stock MAP sensors...

Thanks. That's all I really wanted to know, from the horse's mouth

Did a little research on octane ratings and have found that over in the US, you use a different octane rating system [Anti-Knock Index (AKI)] where as pretty much the rest of the world uses [Research Octane Number (RON)].

So the fuel here is not as great as I thought.

The standard is 95 RON = 91 AKI
The premium is 98 RON = 94 AKI


loads of info on Octane rating on wiki

I would assume an MBC or EBC.

[MSTiFK8R]

also which oil would you recommend to run instead of stock 0W20 ?

cooling the turbo down needs more head dissipation = extra load on the oil

I got my DEFI oil press\temp gauge installed recently

On a warmed engine (90С\190F oil) engine runs 1-0,9 bar \ 13-14 psi oil pressure

On the road the oil pressure seems to follow the tacho pretty fast and pretty straightforward in most cases - 2K rpm for 2bar \ 30psi , 3 for 3bar and so on till the bypass at 6 bar \ 87 psi sharp , no matter how you redline the engine

of course, when it's cold, the oil press could be higher

I wonder how safe is running 13 psi idling on this waterish 0-20W

I got used to see 30+psi idling on my EJ20's and EJ25's , but the oil viscosity I used was never lower than 10-40, mostly 5-50 and 15-50

Maybe there is a sense to reconsider oil viscosity, what would you say based on your monitoring for FRS?

The same way on a standard turbocharged vehicle, via an electronic or manual boost controller, or with a higher psi boost actuator. AVO has new billet actuators coming out with adjustable springs. Actuators set the minimum psi the turbocharger will run at before it cracks the wastegate open to bleed off unneeded boost.

The reason it's essential to have a low psi actuator is so that you can even run a turbo at those boost levels. One of the reasons turbocharging a n/a subaru motor was considered dangerous back in the day was due to people slapping a standard wrx turbocharger on it - which had a minimum 8psi actuator. About 2-3 psi past what they could reliably run.

It's a key factor in any of our turbo kits for n/a vehicles, testing them for the boost levels they can run, and making sure we engineer the kits to run at those boost levels. That's why we have customer that have been running those kits on their cars for 5+ years, a few even 10.

I think some would be interested in the adjustable actuator (essentially an MBC) when running e85. I can already see some people grabbing the kit and getting a separate e85 tune.

It bolts on.

No, seriously. It does. It's amazing. Both oil return and feed bolt onto the head. We did some serious work with this kit.

It'll run ok on that setup, but remember, these are base maps, non-specific to any vehicle. No matter what, for best power/reliability, you should get a tune specific to your car on your local fuel in your country. The tune we provide is very similar to a Cobb Accessport Stage 1 tune. Off the shelf, safe mapping that's only designed for a specific hardware set.

4) have you discussed possibility running Speed Density - oriented flash? That would be a nice option for the guys wishing to leave stock MAP sensors...

We'll leave that up to individual tuners. We have reservations about SD due to the need to compensate for elevation changes.

[Coheed]

SD only for the big power guys. Any change to VE and elevation would likely require a re-tune. I'll keep the maf, thank you.
