OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

maybe they'll put in a super low reverse gear and Toyota will one up them with the lowest reverse range on the market.

Then we'll go from a 30mph reverse gear to barely moving lol

 

it could happen

 

So why hasn’t anybody thought of this before? Just put in a crawl gear and bypass the whole shift to ‘low gears’. When in 4 low in the past, once I need more than first I’m probably going through the gears. With a single granny gear, your next gear up would be first.

 

Turbo sizing is everything. A small twin scroll ball bearing turbo will spool very fast. I don't have either of those features on mine and don't feel like it lags. I step on the pedal and see boost instantly. I personally think SC are antiquated. I definitely don't see the slightly more complicated install of a turbo being a legitimate reason for going with a SC.

 

I believe this was done in the 80's

 

It was very common in the 80s and 90s. Most Ford trucks with sticks had a low gear before first that could be stacked with the low range in the transfer case to effectively give a crawl gearing for use with extreme loads or off road. I think they stopped doing it because the torque involved killed a lot of differentials prematurely when used with a heavy load over rated capacity. Also it wasn't practical to pack in 5-6 speeds with a low gear, that was just too much mechanical into a transmission for a feature that had reliability drawbacks.

 

Even the Porsche 959 had it's "Gelande/Terrain" pre-first gear.

 

Two opinions, yes...in theory, one is correct, the other is not.

Based on what has presented in this thread. The goal is a quick spooling turbo that supplements lack of power down low.

A supercharger is mechanically driven off the crank, so yes, instant boost, but limited...essentially power is more linear. A turbo can create max boost much earlier in the rpm range, if sized properly....more usable power. This is all in theory...so we will have to wait to see actual hp/tq curves. That is why I am keeping an open mind until we see these numbers.

The roots style blowers/twin screw units are very intriguing, as they can deliver some solid gains down low. It may be the best option for those looking for simplicity and low end power.

 

You guys will love the low end if anything like the 2nd gen SC works out for the 3.5L! I have to be careful shooting a gap from a stop ... I have trouble getting traction because of all the low-end torque in my truck. Pulling trailers is a breeze too.

 

Your 4.0 does all of that sooooo much better than the 3.5 even without induction. If I could swap my 06 drive train into my 16 I’d be broke, I’m mean super happy

 

Thank God we've got OVtune. I'm always surprised at the lack of FI support from other companies given the clamoring for FI for this truck. I'd personally prefer a roots blower for the low rpm, low heat, low end power, simplicity and gear whine. Gear whine wins over a blow off valve everytime in my book. I guess if Magnusson doesn't make one for us than it's probably going to be a no-go. I'm excited to see Dyno charts for OV's SC and turbo(s), but I'm hesitant to put turbos on something that wasn't built with them in mind.

 

1. slapping a FI system on this or any engine is easy, its the tune to make it operate correctly where the problem lies. So far as I know OVtune is the only one who has yet to crack Toyota's code to write tuning.

2. how does a SC effect an engine differently than a turbo that makes you hesitant to put it on an engine that wasn't designed with one in mind?

 

I’m not sure why everyone is arguing, we haven’t even seen any details yet lol

There’s a reason both are an option, why will be shown in the info to be released in July

 

I think arguing is a state of being in 2019. I’m gonna buck the trend and just agree with everyone.

The turbo will be both better and worse than the supercharger after neither is never not released.

 

Your agreeing ?! Shit I Donno what to do now! Arguing is 99% of TW! I think we have been defeated!

 

It’s still less mindless arguing than any Facebook-based forum, so I give it a pass on those grounds.

 

Yep! I was drawn in to this thread. Sad to see nothing yet. Oh well happy with the 4.0 especially when towing our trailer. That said the twins in my 335 rock now that they are pushing 17psi. The MHD E30 tune turned it into a beast! Will keep an eye on this one.

 

Just an aside, HPtuners has cracked the code on the 2nd gen Tacoma. I would think that indicates they will have tuning support available for the 3rd gen shortly and HPtuners opens up a whole new level of customization, obviously at the expense of plug and play like OVtune.

 

Your 2nd gen is a Magnuson SC right those I believe are screw type? Those are know for incredible low mid and top end, from research I've done their about the closest available to anything like a properly designed turbo setup. Properly designed I mean as In a usable/streetable truck, not a hot rod.
