OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

So will the right side turbo be close to where the ARB Twin Air compressor mounts?

 

Are you planning on offering the base kit the ability to run the 12-14 psi or will 10 psi be the cap?

 

Sounds like that's a possibility. If so, the air compressor can be mounted elsewhere with ease. The turbos not so easily.

 

If boost is linear and we assume a stock truck makes 225whp, then higher boost would look like this.

WHP ___ PSI
225 __ 0
325 __ 6
358 __ 8
392 __ 10
425 __ 12
458 __ 14

10psi would be absolutely perfect IMO! I may also be wrong and all that down low torque could be a total game changer giving us a ton of what this truck is missing, exactly where it's missing. Personally, I'd love to get the kit, run it at 6psi, and have the ability to switch to 10psi with relative ease (maybe wastegate spring & tune).

 

So here in NM I'm at 7000 ft. how much HP loss do you think I will be at, and what recommendations, i.e. how much more boost and any

 

if there's a switch or easy way to switch max boosts that would be great. 6-10 psi daily driving, 10+ race mode, but for offroading when I gotta be rough on the truck I would like to detune it maybe slightly below 6 psi.

 

I feel like boost psi is becoming the new shift point argument

I’ll go with what mat recommends and not worry about it. He knows these trucks better than anyone else.

 

Yeah but if u run 31.6 PSI in your tires and atmospheric pressure at 4,221' with octane booster in the truck you should be able to run a 6.42 psi spring in the waste gate. It's simple scientific geology.

 

Ha, was just thinking the same. Tune for 8psi, tune for 9psi, tune for 8.5....

 

Hahaha true..but is there a tune for 14psi
Seriously

 

Trying to see a way out of going with the big boi’s but I think I know what I must do

 

Buy once cry once

no one has ever complained about having too much power

 

Those are truly words of wisdom my friend

 

Or buy once, decide you want more and make someone a sweet deal when you upgrade lol

 

This is true. The smaller kit will have its limits at around 12psi. The bigger kit approximately double that but you can always run the bigger kit at 10-12psi and always have more if you want it.

 

Any chance of dyno results of 8 or 10 psi on the base kit?
Don't even need a chart, just curious of "official numbers". 325whp looks great, just hoping for a little closer to 400whp without stepping up to the powermax's.

 

If, and this is an "if" right now. If I can setup some custom code, I can use the purge valve to run a boost controller, and press the ECT button you bump up a few psi.
This has been planned from the beginning because ECT will also be switching to a different map on the boost tunes.

That's an "if" though. I need to sort out the code.

I don't plan on doing a dyno on 10psi right now. I want to get baseline numbers out for both kits first.

 

That would be beyond cool...
I'm going to go out a on limb and assume squeezing close to 400whp out of the base kit is pretty attainable without further modification?

 

What are the drawbacks, if there are any, of running increased boost as opposed to low boost?

 

Drawbacks are simple. more power more problems, same with money.
Of course there's no guarantee you'll experience more problems, but there's more probability, but it will be worth it.
