What kind of Boost Controller Do You Use?

[RPS13-NY]

Exactly what the subject says, and how do you like it?. i have a Greddy Profec B Spec 2, it was included seperatly with my car when i got it, i tryed to get it installed yesterday however im missing the plug that goes i believe from the controller to the solenoid, so should i try and find that plug or is the greddy profec not that great? i was also recomended getting a manuel boost controller.. what are your recomendations for an electronic and/or manuel boost controller, thanks!

manuals cant factor in atmospheric pressures and temps. hot day would be one psi, cold days a very different one

[RPS13-NY]

I didnt know electronic controllers monitor that? So your saying due those factors they are occasionally/often not accurate?

[badbob2121]

im also using the greddy profec b, ive used it on all my turbo cars... and have never been disappointed

take a picture of what you have with your greddy unit and post it, that will help

While the electric boost controller wont actually monitor air temp and pressure necessarily, it will monitor how much boost is being produced, and always adjust itself so that proper levels are maintained.

Think of it this way:

A manual controller is a knob, that you turn, measure, and lock down. Now, at the temp and pressure you set it to, it will be the Set PSI. But should those factors change, the PSI changes unless YOU adjust the boost controller.


On an electric controller you set the boost you want, then IT adjusts itself/the solenoid to the desired PSI, if air temps or pressures change, the psi will change, so the controller will adjust itself so proper PSI is met.

I had an older Blitz SBC in my car when I bought it and ended up replacing it with a Hallman MBC after a recommendation from my tuner. For whatever reason, the Blitz liked to cut boost when it reached the desired setting, causing a drop in boost for a few seconds. It may have just been from the solenoid being old, but the Hallman seems to hold the desired boost setting a lot better for whatever reason.

I live in Michigan where the temperature changes a lot from season to season, but I have never really noticed a huge change in the boost levels between temps. I guess I have noticed a small decrease in boost in certain temperatures, but it has never bothered me enough to adjust it based on the weather.

Yeah but doesnt the Greddy profec work by %'s not a specific PSI number rite? from what i researched you have to drive the car at different percents and see what ur boost gauge tells you to figure out what % you wanna leave it on..?, So far i guess ill just search and try and buy that plug and use my greddy, nobody really dislikes the Profec B spec 2 and id rather go with an Electronic over manuel.. jus looks cool in your car thats the only reason i prefer electronic lol

Looks and sounds like a good boost controller, it says b/c of the dual solenoid it gives "maximum boost response" but all boost controllers do the same job.... it kinda seems like a reg. boost controller w. a screen to show pictures that arent really neccessary lol

Its specifically designed for TWIN TURBO applications.

You don't seem very knowledgeable about boost controllers.

ill take it from the top:

Dual solenoid means that each turbo has its own solenoid meaning that the boost reading your getting is very accurate.

Yes in away your right when you say "all boost controllers do the same job" here is the catch though some do the job better than others for example this boost controller that i use is top of the line (for Twin turboed applications)

Manual boost controllers are the worst over time they move with vibrations and they don't automatically dial their self in.



( I should have never posted what boost controller i use in here because its a completely different field sorry for wasting your time lol)

[RPS13-NY]

Hahah yeah i was gunna say.. What do i cate about a TT bc...? But thats cool u have a tt 300zx there so hard to find in good condition

HKS evc 6. its fantastic you set your desired psi and it does the rest.

[RPS13-NY]

Yeaaaaah, that hks controller looks really nice and u can even tune boost settings thats sick. hks makes so many great products.

[kouki munster]

One of the best ~$600 I've spent, totally worth it and i would do it again without hesitation.

Crap... i actually am missing more stuff then i thought... HELP!!!!! lol. i think i can order replacement parts off Greddy, i just dont know what im missing -,- and im not sure you can actually order it through greddy, it says prices and part numbers but no ordering options.. well this is a pic of all i have if someone can tell me what im missing id appreciate it if not i guess ill have to sell/scrap what ive got and buy a new 1 =/

[biggie]

Search Greedy's site or just google, should find a pdf for the product and a parts list.

[RPS13-NY]

Lol thanks to the inspiration of biggie, i searched some more, and orderd my missing "Replacement Boost Control Valve Harness" [$26.31 Shipped] hopefully thats all i needed too install this thing, eventually im gunna get one of those HKS EVC evc 6.
