Do I Need A Boost Controller?

I'm very close to having my hks gt-ss turbs put on my 32r an aiming for about 300 - 320kw atw.. I've got all the supporting mods ready to go on at the same time but i'm not sure if i need a boost controller?? Most reputable workshops say i do but one workshop (one of the best) says he just whined up the actuators and modifies the standard boost controller.

I want the power to come on nice and strong and i know a good ebc can hold the wastegate shut etc for quicker spool times, but will it make any difference with these particular turbos say running 20psi?

Also will i have trouble with boost spiking using the standard controller at this boost level??

I don't want to have any issues with the car and if i can save myself $350 - 400 for the same result, then i'll definately go that way..

dont skimp on money now!!! buy your boost control

That's not what i was asking race_snooze.

I was asking if i NEED an aftermarket boost controller AND is it safe to use the modified stock boost controller with correctly setup actuators?? Anyone with experience??

If you're going to run 20psi through it, and you're not willing to pay $400 to make sure its safe, ask yourself what you'd do if it DOES spike and you lose either the engine or turbo or both...

I've got another suggestion, at the very minimum go onto ebay and buy a turbotech boost controller. They're recommended by many on these forums and work different to the stock solenoid or bleed valves. Not sure what R32's have stock, but these manual boost controllers are only ~$40 incl postage and they work fantastic. You get the quicker spool up the same as with an ebc because the wastegate sees no pressure at all until the limit set by the manual controller. Rather than bleed pressure off like a bleed valve, it actually restricts pressure to the wastegate and is very reliable.

I'd recommend running a good ebc at those boost levels but thats your call.

LOL.. I'm not trying to be a tight arse, i just thought that if i can use the stock one safely, i would & save some $$, but thanks for the info anyway :nyaanyaa:

With GT-SS - you might need one. Only because they are small and you need every bit of help to keep the gate shut and avoid creep in upper RPM/high boost.

Im running around on 1bar ATM just off the actuator, yet to see if i'll need one but ive been told for 18psi probably ok. Much more if i wanna hold the boost in the upper RPM its likely i will need to purchase for 20+psi

I ran 24psi with ext gate and no controller - never had spike issues (bleeding upto 8psi) on my old setup :nyaanyaa:

Its all about if the person knows what they are doing.

I've never had a EBC on my cars in 5 years :worship:

Im running a turboxs ball/spring boost controller (basically same as hte turbotech one) that came fitted with my mildy modded 32gtr. I was going to get a ebc, but figured i'll be spending $$$ just to adjust boost to and from its peak. This controller builds boost just over 2000, comes on hard & holds it very well to redline. The standard solenoid is still in place and working. The turboxs item has been installed by a workshop just above the turbos.

Well ur a gurl Ash, who didn't watch enough Voltron ... hahah jk bruv :ph34r:

Like Ash says, if your bleeding a small amount from nominal gate pressure, ur ok with Turbotech etc.

Its really only the upper echelon of rice and self richoness that you'd want a EBC to bleed more then 1bar.

Sup to you man, if i was you, id run a $40 manual bleeder. When you start wanting more max target booost then actuator... or if you want more controll over boost rise.. go EBC.

Each to their own I suppose. I personally would have a boost controller. sure u can stiffen up the wastegate spring to run higher boost but wouldnt it be easier to have a boost controller for ease of boost adjustment?

^^ Quieten down, my old boss f_cked him mother often, though NEVER was careless enough to drop boost.

100's maybe 1000's of people don't experience what you have. Grind it out and figure out why your setup with a TT isn't working.

Ultimately i think a EBC is the way to go, but using a manual bleed / TurboTech is still completely fine. With the price of one, do it, at the very least it will give you a good feel of what a EBC actually does when setup correctly.

$$ for results, you cant beet a good bleed / Turbotech style device.

      Stock RB fuel pressure is near enough 43.5 psi, so the latency in that table at 31.6 will be close. You can see that 7 or 8 psi equates to about 0.4µs extra latency. So if you wanted to interpolate between the 31.6 and 39.9 psi values you could say you're going up about 2 psi out of those 8, so add about 0.1µs, which is barely worth talking about and is quite possibly wrong because ideally you would fix the latency while running at the appropriate conditions on the dyno, with a wideband sniffing its butt.

      The pressure, is what you set the fuel pressure to. If you have the factory fuel reg, you'll need to find the factory spec. I don't know it off the top of my head, but someone else might.

      Belt flex under throttle

      By MBS206 · Posted

      For others, what GTSBoy states here should be paid attention. Why? Well lots of people play with different engines, and they LOVE to change things like remove AC, or steering pumps etc, and it lends to them needing to move the tensioner too. You want your tensioner, particularly those that are sprung or hydraulically tensioned, to be the first thing after the harmonic balancer, or technically the "last" pulley in the chain. By saying last pulley, I mean look at the direction the crank spins when the engine is running, follow the belt from where the crank is pulling the belt FROM, and keep following that until you're between the last pulley/accessory on the belt and about to reach the crank again, this is the spot where you put the tensioner. This is the area that will always end up with slack. This is worked out exactly the same way for chains too, as the physics is the same for them. The crank pulley is where all the force to drag the belt around comes from. You will never ever get rid of the slack that appears, especially under load. The tensioners job is to keep the belt loose enough when stationary that there shouldn't be out of sync movement in slow movement, and then be tight enough when running, that the belt can't jump off any gear and get damaged. Too tight, bad things happen, too loose, bad things happen. Have a tensioner (mainly sprung/hydraulic one) in the wrong spot, it can't actually do anything about keeping the tension.
