people need some help. want to get your views on boost controllers. apparently a good electronic one ( blitz greddy ETC..) help your turbos spool quicker. how ever a manual one (TURBO SMART BOOST TAP) dosent help the turbo spool as quick as the electronic one..

so whats the go here. is some one talking s@#t again or is there genuinely a diffrence in between the two.

much appreciated loky.

manual boost T's can be prone to spiking.. cheap alternative to an EBC, they are piss easy to install - i've found stockish turbo cars work fine with manual T pieces so long as your not running like a billion psi.

EBC's are convenient as most these days you can preset multiple boost settings. Also you dont have to pop the bonnet / get outta the car each time to adjust boost. Obviously more expensive than a manual T piece and installation is more in depth.

about the spooling earlier part - dont think an ebc will make your turbo spool quicker, would have though that is more to do with the tune / turbo

They may spool earlier only because the EBC keeps the wastegate position shut until the desired boost level is met, so you actually build boost faster and a few of the other benefits are tuneability of the gain functions to control overshoot and settling time etc this is sort of what the "spiking" defari was talking about.

Ive never used anything other than bleed values, I've never had problems.

Its all about the design of the value (turbosmart ones sadly are bad). And how its installed and combined with the actuator.

Bleed valves don't have any inherent problems and neither do EBC's.

As stated above, the advantage of an EBC is easy setting of levels, multiple level settings and the ability to hold the wastegate shut until a certain boost level. This keeping of the gate shut, helps spool the turbo up faster but has to be finely tuned to be effective. Too early and there is no benefit, too late and it will spike.

lol @ geraus. thanks guys just wanter to clear it up. as the car is at the tuners now and my hks electronic one shit it self and i couldnt get my hands on a electronic one in time and my tuner was busting my chops to get an electronic one coz of the reasons above. im only running 15 pounds on standard turbos. just got bigger injectors fuel pump cam gears and a power fc. hopefully all should be well

my TurboTech manual boost controller doesn't spike at all,

they are a slightly different design to a bleed valve.

Should check them out they are about $30 and extremely easy to install!

Anyone else using the TurboTech manual boost controller, what are your experiences?

Looks like AutoSpeed found them good value for money but that was back in 2005.

Turbotech are a good product.

In my experience, as the boost level climbs, slight incremental turns can lead to large changes in boost. For a stock turbo or modest boost levels they are hard to beat.

(I am sure others have had success with higher boost levels).

I ran one of the Turbotech T's for over a year on a stock RB20 and RB20+25 turbo, good pieces of kit and excellent bang for your buck.

I now run ProfecBII's in both my cars. Had no trouble controlling the violent onset of boost an RB30 + RB25 turbo gives, and has no problems on the wagon with the highflow turbo either.

Turbotech's are great! best bang for your buck if your using stock turbo. When first my brought my car, it use to hold 10psi all the way to redline! works great.

Thanks guys, sounds like TurboTech is the one to get when on a budget!!

EBC can spool turbo up quicker by setting the gate preasue. which will only allow the waste gate to open at a set psi. A good manual valve will do the job though but as stated before turbo smart boost t's arnt much chop.

Thanks for reiterating what everyone has already said.

i have had both a bleed valve and now an EBC.

bleed valve was set to peak at 19psi and trail off to 18psi i ran just over 300rwkw with it.

i now have a EBC and the benefit is that i can safely run 22psi without worrying about it spiking badly, and it holds peak boost better. as for faster spoolup i havent really noticed it too much.

the main benefit with EBC is low vs high boost i can change by the push of a button, because traction is slightly better when running 16psi and putting out 280rwkw than 22psi putting out 350rwkw

but the EBC did cost over 4x as much as a $100 bleed valve (incl. installation)

Turbotech are the business for the price...dont bother with any of the other bleed valves...turbotech is not a bleed valve as such...they work brilliantly, I dont know why people need 5 different boost settings...if you need to turn it down to accommodate weather or whatever, just pop the bonnet and adjust it.

Im using PFC EBC only because it was already fitted to the car...

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
