Default so hydra controls boost, kinda like a apexi avc-r would ??

I am 90% sure I am going to be getting a hydra when my set up is being done and with this said, I have a greddy profec B spec II EBC. I have been reading up on the hydra just to learn more and I couldn't find a 100 percent clear answer, but anyways. My question is will a boost controller be obsolete when I have my hydra tuned, b/c it seems to me like using a avc-r you can program boost levels for certain rpm's and loads (while in a certain gear)...If I am incorrect please correct my, im just trying to get educated on this...Thanks

B/c if the hydra can't I was looking into the apexi avc-r to be able to control boost levels in all 6 gears.

no you have to option of using the hydra for boost control or you have use a manual or electronic boost controller , but you can use the hydra to set the boost level for each gear

So if you need to have access to multiple boost levels without downloading a new map, a stand-alone boost controller may be a better choice.

Phil explains above why he uses the e-boost.

Let's say you DON'T have a 600hp car, and you're not scared of the power of your car in wet conditions, is there any downfall to using the stock boost solenoid with the Hydra for boost control?

I'll be running the Hydra with the Hydramist on the GT52 turbo (no PSM-04-STi, I'm not just trying to be like you ) I like the idea of the Hydra switching to a low-octane auxilary map when the flow of the Hydramist is interrupted.

Basically, trying to find out whether I want an e-boost for my car. The only time I see taking my car to the track is maybe for a 1/4 mile run, but that would once in a blue moon. Daily driver most of the time.

Stock boost solenoid and GT52 = not a good combo, you won't see the full potential of the turbo

I know your not trying to be like me, you don't have the Element EWG up-pipe

My 06 STI with the GT52 was tuned with the Hydra and OEM solenoid for some time. It works well but for racing I really needed on the fly boost adjustment of the e-boost 2. My street car (ex Time Attack WRX) very much detuned by my standards has an STi engine, VF30, STI TMIC, Turbosmart BOV, 800cc injectors, Hydra, E85 fuel, and I'm using the Hydra to control my OEM solenoid. It works very well if you know how to tune it as you have start RPM, real PID control, boost targeting, duty, and gear based compensation. For my street car that doesn't even have a boost gauge it works great I do have another e-boost which I may install if I get bored

For those with weak internal wastegates the OEM solenoid can only do so much. If you've got a basic setup or you are running an external WG with a stiff spring the OEM solenoid can work well. If you need more bleed off then get something like the Prodrive solenoid. I think I'm actually going to test on of these with the Hydra in the near future. For our Time Attack car the E-Boost 2 is the best!

Thanks,
Phil

Thanks for jumping in Phil.

Whatcha think of the DTEC as a replacement boost controller?

Also, can you share info on a possible new Hydra coming out?

BTW, great job at the Seattle SubieFest Time Attack! I was the 4th place driver (in Jarrad's Legacy). Amazing job learning the track in one 15 minute session and massively undercutting everyone's times. Better than the Z06's I've seen at Pacific Raceways!

Russ,

Thanks for the compliments and I really wish I could have showed the crowd what the car was really capable of at Time Attack. After taking a short cut through the grass in practice I decided I should learn the track and our new setup first and I took it really easy. No doubt I could have broken into the 1.2X lap range or ended up in the trees.

I have never been successful in tuning the DTEC to the standards of some of the other boost controllers but I know other tuners that have been. There are certain boost controllers out there that just get the job done easier, faster, and more reliably.

There is another thread going on a new Hydra here: http://forums.nasioc.com/forums/show....php?t=1191705

Thanks,
Phil

You're right, I don't have the Element uppipe. That said, I did have World One weld an EWG on my APS uppipe on my APS header

Phil, I'll get one of these Prodrive solenoids and let you play with my setup. I hope that this solenoid with the EWG will work great even for high-boost levels.

I ran a GM solenoid with the Hydra. There are lots of ways to augment the solenoid. From the perspective of the Hydra, the boost control is a feedback system based on a target duty cycle just like many of the EBCs out there.

I like the AVCR for the reason of being able to tune duty cycles per gear. Works fantastic and easily. Plus it automatically adjusts for atmospheric conditions. Definately worth the money in my opinion.

The avc-r only works for 5 gears, so u cant control boost in all gears with it in a 6 speed car.

Just as an update guys I have installed a Element GT52 turbocharger on my daily driver as I needed to do some testing. Since we've redesigned the porting and increased the wastegate flow of the GT52 by around 19***37; the OEM solenoid is a little limiting in flow for this turbocharger now. I can now only get about 20 psi out of it but I do have a Prodrive solenoid I'll be testing. This should do the trick for at least 22 psi. I'll let you know how it goes.

Thanks,
Phil

Hey Phil, I'm the guy that talked to you today about the engine setup for a good 20 mins (btw I really appreciate your input). How would the Perrin EBCS work with the Hydra?

So far tuning the Prodrive solenoid with the Hydra is very easy and it's definitely a performance upgrade over the OEM solenoid. I'm getting higher boost with less duty and it's also holding more boost to redline.

So far I'm liking this solenoid over the Perrin for ease of tuning.

Thanks,
Phil

Good to know.

I don't remember if we got around to putting in the Prodrive in my car, but we'll have one in before you finish the tune.

6th gear is the overdrive gear though. I don't think it makes a big difference. But if someone can chime in, does the eboost do more or less then the avcr. I am really considering selling mine and going with an e boost.

You don't need compensations for every gear. You could tune your boost in 6th gear and alter your compensations for 1-5.

The E-Boost doesn't have the same features as the AVCR but honestly from my experience it works just as well and is so much easier and faster to tune. Both are great boost controllers and very reliable unlike many others on the market. I also like the Blitz SBC-ID for the same reasons but the E-Boost is the easiest to change boost on the fly and that's why we prefer it for racing.

Thanks,
Phil

Yea sure Phil, we both knew the VF34 just wasn't going to cut it

+1 for the EboosT
