Boost controllers...
|

I was just wondering which boost controllers are commonly used with turbo charged toyota vehicles.
please tell me your experiences, i'd especially love to hear what the 3sgte guys have been using.
Can you justify spending $500+ on a boost controller? Is it worth it? Or do you just make do with a cheaper one?

id only use a electronic one which will set u back the 500 bucks.. but they tend not to spike u can control boost curves and lots of other stuff.. the last thing u want is it to keep spiking

I made my own boost controller setup. In cabin switch adjusts between high and low boost.
High boost is gated and set at 20psi, low boost is not gated and is set at 13psi. My boost holds rock solid at both settings and does not spike or drop across the whole rev range.
It works perfectly, is very stealth in the engine bay and cost very little to make.
Performs better than nearly anything I have seen off the shelf. Because basically I set mine up to perform exactly how I wanted it to work

The advantage of the more expensive boost controllers, is that they are gated.
ie. They will block all pressure to the wastegate (or attempt to) for as long as possible till you reach your set boost level. This brings on full boost faster than a bleed valve or non-gated system, which tend to creep. Wastegate creep is air bleeding through to your wastegate actuator before maximum boost is reached, this causes the wastegate to open slightly BEFORE fullboost. Making it come on slower than with a gated system.
I hope I got that right.

Yup. What monkeyMajik said. My Apexi AVC-R is costing me $715ish delivered through Slidewize Imports. It's the duck's guts - can adjust for different gears, has two maps you can set plus scramble mode. Also acts as an ace boost gauge and a data logger (only for short intervals though).
It's total overkill, but then I've got a Ceramic-wheel turbo which will probably disintegrate somewhere around 13.5->14psi. I figure I can set the AVC-R up and monitor boost to make sure I don't get any boost spikes ever. Expensive for a boost controller, cheap if it avoids turbo destruction, or even an engine rebuild if the plastic impeller wheel were to let-go on an overboost spike.
Bang-for-bucks, I'd grab a turbosmart 2-level manual controller. It's a gated bleeder valve with remote boost-switching (hi or low from a toggle switch). $200->400 depending on who you know.

My 3sgte has a turbosmart bleed valve hooked up. It boosts to 13psi without a problem. I don't get too much spiking, but sometimes it spikes maybe 1psi then falls back down. I run about 13 psi on my ceramic turbine turbo.

my g/f's brother is an electronic freak and hes making me a controller that only uses a solenoid and a circuit that opens and closes the solenoid at different rates to regulate boost. if that doesnt work which it prob wont im just gonna use the solenoid to swich between two boost controlers to have duel stage rather than variable boost. boost controllers im using are tightass gardening valves or something, work a treat tho.

Just curious, but with an electronic boost controller, is it possible to make boost come on earlier?
The breathlessness of the 1G-GTE down low is making me curious about this

if you paid over 500 for an avcr you got ripped. Shop around , ebay is your friend. I got mine for $550 brand new delivered, and that was a while ago.

what about them?
They talk about the differences between a gated and non gated system.
I just mean in comparison to a stock setup, to a setup with an EBC.

A boost controller MAY assist with full boost being achieved earlier. You simply tell the boost controller solenoid to vent ALL the pressure from the compressor housing away from the waste gate actuator. This causes the waste gate to stay shut. Unit your boost controller starts letting some of the pressure through to the actuator your turbo will be making as much boost as possible.

seems like an apexi controller off ebay is the way to go.

I am using a Hiperboost controller. It also has the ability to bring boost on quicker. Can't give any reviews yet as car isn't going.
Had it connected for 10mins or so before my engine blew and it was definitely bringing boost on quicker. It was a totally different feel. It felt like it wanted to drop into 2nd at 90kms and I have a 4.6:1 diff!

Before your engine blew?
This wasn't because of the boost controller was it?

$2,000 for a decent programmable ECU (e.g. Autronic) + $200-250 for a decent solenoid... only way to go.
Better than paying $700 for a controller, $500-800 for an AFC, more for ignition control etc. etc.
If you haven't modified your car enough to require a new ECU just use a needle valve or celicamads box o valves until you do require an ECU.
The Jaycar boost control kit would be a good option too.

I would feel ripped off if I had payed this for my brand new
AVC-R.
