OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Game ON!!!

 

Looking for some input regarding boost controllers. Looking into the SCG-1: Solenoid Boost Controller by Innovate Motorsports.

As I understand electronic boost controllers, not only does it afford some level of protection to help regulate boost, but also reduces turbo lag, regulates boost threshold, allows for increased boost above the waste gate spring rate.

Wondering if it is something we should consider installing with the TT kit? Thanks for any input.

@OVTune, any formal rec's regarding boost controllers?

 

I think you can also decrease turbo lag by welding the waste gate shut.

 

Yea these are pre-machined pics. They will be properly cleaned up, aluminum oxide sanded, etc.

LOL DO NOT DO THIS!!

 

Boost controllers can only raise boost past wastegate base pressure.

And I am telling you guys... there is no such thing as "lag" on these damn turbos. If you have the base turbos you see full boost practically off idle.

I do not recommend a boost controlled unless you specifically want to run more boost. Boost controllers can only regulate boost past wastegate pressure.

 

Mat how hard is it on the base kit to add the DI later to get to 10+ psi? If i am not happy with the 6.5psi. Just a little worried with cost right now to add the DI right now been out of work now going on 5 weeks! Hopefully i get back and i dont have to worry about!

 

It's actually not that difficult to do. It's just a little annoying because you have to work right in the middle of the engine bay.
I'd say it can be done in under 4 hours (with hand tools). Power tools would knock it out fast.

 

Okay great no worries then! Thank you!

 

best thing i hear on here ALL THE BOOST

 

To answer your question, the current design will not work with the driver's left vent. I am kicking around the idea of making it universal for either of those vents so 1 design will fit in either location. It will just have 2 different sets of locking tabs.

The cool thing about that is if you wanted afr you could have afr in 1 vent and boost in the other.

But that's enough on this thread I am going to start a new one.

 

I wonder if they 3D print their molds for the casting. Sure looks like it.

 

Maybe not the molds, but I wouldn't be surprised if the patterns and/or cores were.

 

Catted please.

 

What's the reason to keep the PowerMax's with the DI upgrades @ 10 PSI vs the upper limit of 14? Will the same program handle all boost pressures?

As far as cat vs non, any major loses with the cat version? I'm in TN, so either is fine.

Forgive me for my ignorance, but I’m still struggling with the finer details here. I’m going with base + DI and want a boost controller to adjust the psi between 6.5-15. Is that the right way of thinking about how boost controllers work?

 

If you leave the wastegates the way Mat will have them set then yes. You will be able to run 6.5 psi as a base and increase that as you please with the controller.

 

I'm not up on investment casting lingo, but u get it

 

Crazy the resolution you can get though.

 

Definitely. For large castings, even the roughest plastic extruder, 3d printed patterns for sand casting would be fine with some post-processing of the pattern. A lot of small investment castings are done with liquid resin 3d prints directly. The resins are developed to burn cleanly in a burnout cycle so you can pour directly into the molds. I have a friend that is using a Form Labs printer to do custom jewelry that way. At the very least, the molds to make the positives for the lost wax casting process can be 3d printed directly.

Technology makes stuff like these manifolds orders of magnitude cheaper than just 10-15 years ago.
