pplz are they any good im hoping to run 20psi with a high modded car

should i get one or get something else

please let me know

I like 'em

Easy to install

Stable boost

Simple to adjust via Commander

Adjust and log via Datalogit

No ricey blue screen

cheers

I like mine.

But, if you can handle the ricey screen (I would mount it invisibly under the dash or in the glovebox) I would have bought the AVC-R insted of the Boost kit.

Reason? I'd just like to be able to adjust the boost in first gear.

I know everyone, myself included, normally says "Adjust boost with right foot" but I can now see the merit of having adjustable boost according to speed.

Would be great, especially during drag racing testing, to be able to add 0.5 psi at a time to first gear to try to eliminate wheelspin.

my $0.22 cents

well so far so good

im chasing 350rwkw and also will be runninf full slicks when draging so i think ill be fine there

Hmm - let me be the first to set a cat amongst the pigeons

I don't like mine

I have a mildly modified R32 GTR (~300awkw) with PFC + EBC and in hind sight I wish I had spent the extra ca$h up front and gone for the TurboSmart eBoost

It ?may? be just my tune - but I find mine does NOT hold even boost once I hit the max boost setting. The boost line waves all over the place – IE it varies +/- 1psi across the rev range.

Again – I don't know if this is the EBC or not – but that's what I get

I've seen other dyno graphs that are as flat as a tack once they hit the max boost setting

I also find it VERY noisy, it rattles/chatters like the clappers. That ?may? also be due to the fact that mine is mounted high on the passenger side fire wall – which makes it very easy to hear from inside the cabin.

If nothing else – this will give you something to think about

that's my 2c worth

(let the flames begin)

[teazn_r33]

thanks anyone else

[warriorbrawl]

ME have one too

me like alot.

my boost is stable- simple to setup and reliable

To get stable boost you need to have reasonably short hoses to the actuator.

If your's is on the firewall its probably too far away.

If it is installed closer to the turbo(s) ie, the passenger side strut tower, it should control boost better.

(and be quieter)

Although I know nothing, I have spoken to a tuner who doesn't like th PFC add-on, he prefers the AVCR. His reasons were, (AVCR has ) stabler boost, easier to setup and tune, with option of ironing out spikes at specific rpm, more functions. Though it might have been worth a mention.

[Bl4cK32]

the avcr is just the pfc boost control kit + the rice blue screen. Its the same damn controller.

[Robo's]

Great unit, its the same unit really, i was missing the PFC sensor kit so i bought the AVCR one as its the same. Basically its the same without the rice blue screen.

And mine keeps boost very well.

so - any other suggestions as to why my unit does not hold a steady boost ?

If you have a nice stable consistant wastegate then their good but if not use an EBC with its own MAP sensor.

The Boost Control Kit comes with a MAP sensor, the same MAP sensor as the AVCR.

The Boost Control Kit solenoid is the same solenoid as the AVCR.

That would be a lazy tuner. I would say the tune on the engine is substandard or it has other issues causing the boost to fluctuate. Instead of fixing the real problem, he prefers to stick a band aid on it. Use the boost controller to cover up for other issues that really should be fixed.

Technically speaking, boost is load dependant, not RPM dependant, so making boost corrections based on rpm points is not correct. It might smooth out the boost curve on the dyno, where the load and gearing is exactly the same every time. In the real world, that is simply not the case, where boost is very much gearing and load dependant. For example, you could be applying a boost correction at 6,000 rpm in fourth gear that is simple wrong at 6,000 rpm in second gear.

Next time someone tells you that rpm boost correction is a good thing to have, ask them to explain how they get around the effect on boost of differing loads at the same rpm.

I am also curious. Would it be better to spend the $$ on the kit or buy say a Blitz Dual SBC Spec R which I have not found onje bad review for.

The Spec R is dual solenoid and everyone says that its the best controller out there.

I have read mixed reports about the AVCR and its reliability. This would then flow on to the boost kit since they use the same components.

How much boost are you running?

What turbo?

What is the wastegate spring pressure?

Maybe you are trying to bleed off a bunch of air. Could be remedied by a bigger wastegate spring....

R32 GTR with freash forged motor and R34 N1s - running (only) 1.2bar (18 psi). Using the std N1 actuators (waste gate spring ?)

i always doubted the avcr "gear boost" functionality, thanks for clearing up

Get some street R series tyres and then you wont have to worry about hi boost in lower gears.

[paulr33]

my thoughts (altho i didnt voice them). sort out the traction issues, just imagine how it would go if you had grip
