OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

What I meant was that @OVTune mentioned they wouldn't be making 87 octane as an option since they couldn't increase power as much or at all.

Ecoboost engine's lower compression ratio than the 2GR, is what allows them to use 87 much more effectively. They don't really lose much power compared to 91/93.

Hell if all we got was a 50 tq/50hp increase with 87 on the SC, I would still be happy with that, but chances are, that isn't achievable.

 

It's definitely not an easy decision given the price points, but as you mentioned, when it's all said and done, Turbos would likely run more expensive.

I don't believe an extra 1.5 psi would hurt much, anything under 7-8 psi seems to be safe for most unmodified engines.

At this point, my only concerns are final SC numbers, mpg loss due to it's parasytic nature, running premium fuel(Which would cost about $7-8k after 5 years given SC cost + extra premium fuel cost) vs simply upgrading to a new vehicle like the next gen tundra which I have been on the fence about.

Gotta see what comes out first, and by then, hopefully we will have a lot more hands on info and details about SC or TT.

 

I could probably combine my Taco and Cayman into a Cayenne GTS for about the same price tag. I’d get another 1300 lbs of towing, and 400 lbs of cargo capacity. But I’d give up a pickup bed and a manual weekender...

Nah, just going to keep what I have and make it work within the limits.

 

Plus, I don’t like driving that much money as a daily.

 

Ecoboost engines recommend higher octane but will adjust and run fine without it. Unless I'm wrong my understanding on these 3rd gen turbos and S/Cs is that they will require higher octane fuel. Putting 87 in will cause it to run lean and running lean spells death for any engine.
Same as with the TRD superchargers for 1st and 2nd gens...cannot run 87, you must run 91 minimum.

 

Not quite. Putting lower octane fuel will cause pre-detonation and/or pinging. Those conditions CAN be caused by running excessively lean, but in this case they would be caused by inferior fuel not having the detonation resistance that premium fuel does

 

If you look at the TT vs the SC, have to remember that the SC runs off crank speed so is only good on high end. Specifically more so when it's a centrifugal model. It will be a bit tougher on engine due to drawing power to make it work. But on other hand, the TT when towing will boost even faster due to the engine being stressed more, IE long gears, less shifting, added weight yada yada. For pure fun either is fine, but Turbos are significantly more effective and efficient than a SC engine. That fact is obvious, ford even knew this, that's why their engines are all turbocharged not supercharged, add wastegates and you can make a small turbo hit boost instantly then gate so it wont overboost, such as the EcoBoost, and the OVtuned 3.5 TT, charts show its boost being rapid, even at 5psi if you drove it with a camping trailer like a 5K model uhm, a Jayco model. Stock truck then a tuned TT truck, the TT will have much smoother take off ,cruising and hill pulling, you won't really gain much with a SC unless you have a pulley to make it spin faster than before to up the boost in the *Sweet spot* that you the driver personally run your truck at. I've had the privilege to be in both scenarios, a single turbo, twins and compounds (person 4bt Cummins truck), and a supercharged SS cobalt, and a 750WHP GT500 Shelby, while the SC has a incredible linear pull all the way through unless you're in the top of the revs, the boost is only SO good. Not saying it is not worth it for some, I'm personally after boost everywhere, off idle to mid range and high end.

 

Patiently but verrrry anxiously waiting for those 10 PSI dyno numbers!!!

 

Hey @OVTune can I get a discount on a turbo setup? If you agree I promise to personally throat punch the first 5 people to complain about their gas mileage after installing a kit.

I think it would make both of us feel better after all the hard work your doing and reading some of the negative comments.

Btw I’m just joking.... keep up the good work! Hope To have a tune and kit soon.

 

You would lose so much money on air travel alone. If he was a smart business man, he'd take you up on that deal.

 

Fairly certain he’d drive his turbo’ed Taco!

 

Depends on the contract! Either way, fuel would be crazy!

 

@Grand dude turbo thread

 

So I’m just curious what everyone’s thoughts are on how risky the turbos would be on this truck. Mat has already mentioned the gains on the 5psi setup which I’m assuming he is calling the ‘base’ setup.

How likely is it that the other components of the truck fail with all this added power? I drive a manual so I already know the clutch would be a weak link but I’m curious how far this goes. Seems to me like it’s a ton of added stress on everything from u joints to transfer case, transmission obviously, CV joints, rear end even.

I’d love to get these turbos and have some serious fun with the truck. I can live with having to get a new clutch. But if I have to start thinking about a tranny swap and blown transfer case it may be a hard no for me.

 

Valid concern but I’m somewhere between “not concerned” and “don’t care” because:

1) Toyota is notoriously conservative, taking quality almost to an extreme

2) I hate the lack of power so much that if it weren’t for this turbo setup, I’d likely be buying a tundra or raptor in the next 12-24mo

3) fixing broken CVs or other moderately expensive items, maybe even trans, would still be cheaper than buying a new FS truck

4) While he’s no Toyota engineer, I trust that Mat will do the research and testing to know what these trucks will handle and dial it back from there.

 

Also mat tortures his test truck so he can find the limits so we don’t have to worry

 

I think a lot of that will have to do with how you drive it. If you dump the clutch every time you leave the driveway, red line and bang through the gears, those parts will obviously not live as long. Roll on the power once you are already moving and it won't be so bad. I had an 06 6 speed previously, and I did not have enough faith in that transmission to add any power. I know the new one is different but I don't know anything about it.

 

Its all about how you drive, if you dump the clutch with the steering wheel at full lock in 4wd, your CV shafts wont be too happy but that wouldn't be a good idea on a stock truck either.

Also your transfer case is a torque multiplier (X 2.xx) so when you go into 4lo, you're putting alot more torque through your driveshafts, CVs and rear end then this kit will be putting out
