PFC Boost Kit v/s EBC (Blitz SBC-ID)

[nocab72]

Forum just ate my last attempt to post, so this one will be shorter...

I've fussed with just about every boost controller available installed on either RX7's or Supra's, because at least in the RX7 world noone would even think of using the PFC Boost kit on their single turbo 7, with stock twins yes, but that's it.

I'm new to the GTR world, so excuse my ignorance if I show any!

Reading the various boost controller threads, I've noticed several individuals recommending the use of the PFC Boost kit when using the PFC ECU on a upgraded twins or single turbo car.

What advantages are there to using the PFC Boost kit v/s a full featured EBC besides the following two: (which haven't sold me on using the PFC boost kit)

1) all in one ECU/Boost control makes datalogging easier, but if the car is a MAF car and you tune the PFC map via 20x20 map and are at 15x15, you got there via MAF v/s RPM, who cares what the manifold pressure is?

2) PFC Boost Kit is a couple hundred bucks cheaper than SBC-ID

Am I missing something, or is there not a reason to give up the richer feature set of the SBC-ID in leu of the PFC Boost Kit, ie 4 settings, dual solenoid, speed based boost, better boost/gain adjustability, better graphing/peak/hold, etc, and another cool looking HC, lol

Thanks for your opinions!

I went down this path with my PFC, and in the GTR World, it's the opposite. The PFC Boost Kit, is a single soleniod unit, apparantley similar to the Apexi AVC-R with less features.

After speaking to my tuner & one of Austalia's best GTR tuners ben @ racepace, their replies to my question which EBC for my GTR is best "without any hesitation, the HKS EVC 3, 4 & onwards" Others may have different opinions, but I'm always trusting the above 2 tuners opinions.

Also, [someone correct me if I'm wrong] the closer your actuator is to your boost target the less harder your EBC need to work. A problem with single soleniod ebc's is they cant keep up with the demand of a twin turbo. The HKS is a dual soleniod & has a unique stepper motor.

[nocab72]

Correct, you want your actuator or wastegate spring set as close to your target boost level as possible, this allows the spring(s) to do most of the work and the EBC as little as possible. When there is a large difference between spring weight and target boost, the EBC has to work very hard to keep the wategate closed while trying to reach the target boost level.

The HKS is a dual soleniod & has a unique stepper motor.

Yup, SBC-ID claims the same.

Im stoked with my EVC5. Does its job very well.

Yes, the HKS EVC is very nice... good value at the moment too

Hi nocab72, we use Power FC boost control kits (PFCBCK) all the time. I personally like the abilty to use the Commander for all setup. The PFCBCK has the ability to have as many different setups as I want (so "4 settings" is redundant). I don't care about "speed based boost", I run full boost all the time and if I want to go slower I don't push the throttle pedal down so far. I have yet to find a problem with "boost or gain ajustability". We use a Datalogic system, so I don't think any stand alone unit is going to give "better graphing/peak/hold". I sure as hell don't need another "cool looking HC", I am too busy driving to bother looking. If I want to know what happened later, I can look it up on the data log.

I am not sure what you mean by "who cares what the manifold pressure is"? I certainly need to know the boost level at all times, this is great diagnostic data as well as very useful for tuning. Plus I don't know any other way to compare the aim table for boost and the actual boost achieved at any point in time.

I am not sure why I would want (or need) to use two solenoids, I suspect it may be because I chose the wrong wastegate actuator's (or spring/s) for my boost level. But using a boost controller to fix this shortcoming is a band aid, I would much rather fix the real problem and get the right spring rate in my actuator/s.

Lastly, the extra "couple hundred bucks" saved, I use to make the car go faster by buying something that will achieve that aim.

Hope that explains my position.
