Ebc Will It Bring Boost On Sooner?

[dangerous_daveo]

Hi all. Just to kick things off I have spent the last 30mins doing some searching on here in to EBCs (electronic boost controllers). Now with my search I found some stuff that confirmed what I already knew. But not a direct answer to the following question. So if its out there, feel free to do the search and post the link to that topic. But I couldnt find it.

Anyway question.

Will an EBC bring boost on quicker than say a good quality bleed valve. Engine is an RB20, stock turbo, 11-12psi with the bleed valve. R34 sidemount intercooler. And dump pipe back exaust (ie stock dump pipe). Its also got a dr drift chip.

The bleed valve I have atm holds 11-12psi pretty good (12psi on a cool night) doesnt spike, is fairly smooth etc. So from what I found out the EBCs work well and solving that, if thats a problem. Which it isnt so I cant justify the cost on that.

But if boost can be brought on sooner, say 500rpm sooner then I could see it being worth the money.

Just to add to the above my mate has an older hks one that he is willing to sell me. Not 100% sure of the model, but its a bit old.

the only time it would bring it on earlier was if your gate was leaking or opening too early

ie: if the gate was opening say when it started 3-4psi even though the spring is say 7psi

it could being to open prematurely. with the bleed valve it just limits the signal to the actuator

an ebc can block the signal completely until target boost is reached and then show the signal to the actuator

or it can slowly bleed pressure to it progressively from say 9psi so that wont spike its ass off

in your case, it wont do anything most likely

but there are some advtanges to a good quality EBC

- digital readout, no need for a guage

- overboost protection, so if something changes it wont just ramp to whatever the engine feels like (except for human error with wastegate signal)

- corrected boost control (during summer and winter it shoud always be say 11psi exactly and not spike to 12.5 when its colder nights like a bleed valve would)

you dont have to pay billions for an ebc

i was against paying $500+ for an ebc so i got an old school style HKS EVC II, works well and does everything i need, set and forget

EBC's do not bring boost on earlier, they just hold boost at your desired better without dropping and rising boost levels. It results in more consistent power and makes it easier on the tuner.

If your having troubles with building boost, it could be something to with wastegate actuator. Older ones start to loose their tension after years of work. A Good replacement would be the HKS adjustable wastegate actuator.

i had a bleeder then went to an avcr i love it lol

[dangerous_daveo]

Thanks for the replys. I should have pointed out its building boost ok. Just if it could be a bit better it would be nice.

PaulR33, i think that HKS EVC II is exactly what my mate has, it rings a bell.

[BAMR33]

You must love the blue screen as much as I do 'sinistagtst'. lol

I'd say if you get an EBC make it an AVC-R for the cool/wank factor.

[paulr33]

half the price of the avc-r

hey dave, just remembered what Sam (Dr D) said when i was getting mine tuned, he said it wouldnt make any difference having an ebc, cause i have one sitting at home i didnt put on. the thing that will though is your dump pipe i reckon.

though ebc's look mad as.

I get better boost responce with my ebc on, if i turn it off the car is laggier

[RB30-POWER]

If you run one of the jaycar autospeed electronic boost controllers, yes you could bring boost on sooner, as that system uses the solenoid directly inline with the wastegate actuator, instead of just bleeding boost off it controls the boost getting to the actuator. If you keep the solenoid 100% closed until you have the boost it will help eliminate wastegate creep that is typical of some other systems as no pressure is getting to the actuator.

[Howie]

The blitz dual solenoid progressively builds boost as you desire... if you up the gain from something like 5 to 10 you'll see that it builds boost alot quicker, up it once again and you run the risk of overshooting your target boost... but it builds fast if you like that sorta thing.

Yeah, so the answer to the question is no it doesnt bring boost on earlier. Its a stock turbo, its goes from 0-11psi pretty quickly.

So without starting a new topic. Given the mods I have, and the little money I want to spend (better brakes, and semi slicks will be money better spent to get going faster...) what would be the best bang for buck to bring boost on a bit sooner.

[BAMR33]

Dump pipe for sure.

How much is 'little money'. If I had my time again I'd do the suspension first, such a difference and I didn't think it was too expensive (SK group buy).

Response from the standard turbo's generally can't be improved on that much, because they are designed for response. You could try all the little easy things like CAI with multiple intakes etc. But besides that your going to have to look at turbo upgrades and injectors etc. which start to get expensive quickly.

half the price 10 times uglier and doesnt do as many near cool things the avcr does lol

Yeah, everything else is done other than engine stuff really. Already got SK suspension gear on there etc. I might do the dump and leave it at that.

I'll also see what my mates going to charge me for the ebc. If its $100 or so its probably worth it.

and avcrs ask for your windows to be broken for a smash and grab

Really though, what else do you want it to do other than control boost correctly..?

Kerrist I don't even have an lcd display on my blitz twin-sbc, but it controls boost nicely and does its job well. Better than wasting money on something that is a set and forget, as well as a smash and grab target to whit.

Probably want to get a decent dump / front and attendant exhaust.. that will make the most difference at the stage you are at.

agreed i have the blitz twin-sbc awesome boost controllers, and the solenoid looks the part under the hood

[tridentt150v]

Yeah I've got the Hks evc III, it's a set and forget, and like Paul said, boost is stable.

Plus you can get old school stuff for less $$$ and it does exactly the same job. Only thing you can't buy is the cello wrapper and the wank factor [pretty blue screens that attract crackheads like roadkill attracts flies].

[sinistaGTR]

mine is in my centre console hidden, i just love the ability to program boost per gear, revs how ever you choose, i find that if im running say 15 psi in first my car is useless in first but program it as you please and it works a treat. for cars running say upto 230kw a basic evc will be fine, just more power traction is harder to control if your running heaps of boost.

[BAMR33]

Mine is clearly displayed near the middle air vents, and it always gets impressed reactions from people who haven't been in the car before. I have a second car so I don't have to worry about idiots stealing it
