Is this the best boost controller to date?
 

http://66.216.67.51/product.asp?0=208&1=243&3=723

Has anyone used this?

I have the PFC and with MP I am worried that it won't be enough.

Wastegate has been ported.

I like the fact that the Greddy can smooth out the boost curve.

Please share ur insights.

I don't know, to date, I would have to say the greddy, I used to date an apexi but we did't get along and werew both going in different directions :evilgrin:

it looks the coolest! lol

I hear the SBC ID is the best one...

although for twin turbos I think the profec B is still the best

i think its the profec but thats on twins. i dont know about single but does it make a difference? i can keep me profec for a single too right???

looks interesting. something else to look when i go single.
now someone get that man a spellchecker.

Batman, I'm nowhere nearly qualified to answer your question...BUT...if you take a look at this thread

https://www.rx7club.com/showthread.p...ost+controller

I have a similar setup as you do...PFC, DP/MP, and was worried about boost spike.

A lot of very knowledeable ppl posted on that thread...and basically the main conclusions were best thing = porting the wastegate, followed by profec B, and a relief valve was suggested as a backup

So if your wastegate is ported, I'd think you'd be OK? (unless you're going for the bling factor in that greddy unit haha) Hope that helps some.

I too heard that the profec B is the best, at least for the $$$.

Would it be fair to assume that Greddy's best one ( as posted) is the better/upgraded model?

Again...not qualified...but just a word of caution. Not sure how long that one you referred to has been on the market, and how many ppl w/ FDs (and w/ twins..at that) have used it.

Only reason I bring that up is I was about to jump on Greddy's new Profec B...the Profec B Spec II...until a bunch of guys started reporting issues w/ it not working about 15 psi, and resetting automatically... etc

eeekkk!

I say that the Profec E01 coupled with the e-manage is the best boost controller to date. Not saying that its the cheapest though.

yea u can say that again..it's expensive as hell. but it works really well i take it? (for that price...it better! lol)

can anyone confirm/deny the wastegate thing? cuz i thought a ported wastegate (enough for your particular boost application) would remove the necessity for a boost controller??

Sidenote: imma ask this at the risk of getting flamed...i was always curious...in 2 Fast 2 Furious, the air that was blowin out/being vented from the Skyline when it first arrived ... isn't that via an external wastegate?

Im gonna say no because without some sort of boost control its going to get way out of control.

im tryin to understand how it would get out of control...cuz im thinkin as long as your wastegate is ported enough for your application, wouldn't it always be able to vent excess boost??

if that doesn't work, it seems pretty pointless then to port the wastegate in the first place...

Yea but without some sort of pressure control your turbo is going to keep building more and more boost. The wastegate is more than likely going to be in the closed position. The only reason that I would port the wastegate is to reduce boost creep.

I have the Profec E01 now, and im changing to Blitz. Cause i don't like the auto boost adjust program. It takes to long to adjust.

And u can only controll one turbo. Not both. I have tried this and it did not work
