OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Can confirm the hybrid option. It’s being made in WV.

 

I cant tell if this is tundras.com or the tacomaworld ovtune FI thread anymore...

 

We’re talking about forced induction applications that will be upcoming to this motor. Can’t tell why you’re guilty of your own annoyance with multiple instances of posting like this

besides, he’s already said he’s taking a break from the forums because of what can only be because of the incessant DMing and tagging from people. Anything not on page 1 of this thread will be forever buried. Complaining about the conversation 157 pages deep is

 

You must be new here, nothing ever stays on topic

 

On another note, when are we getting the supercharger numbers?

This is what the OV page says

"Estimated gains (as tested on 7GR) 80+ ft lbs / 100+ HP gain at 6.5 psi "

@OVTune

Do you still believe this to be true, or has the Tacoma engine shown more potential than the other 3.5 engines from Lexus?

 

7GR-FKS is same exact engine as the tacoma, just rebranded for asia.

Note, I amy only make a few posts here but generally won't be on.

 

Ah I see, thanks for the clarification.

Looks like it will be a choice between ease of installation and possible mpg loss vs more hp and a more complicated installation, since the prices between turbo and sc are surprisingly similar.

Hopefully the SC doesn't sound as bad as it did on the 4.0, although I suspect that was mostly the SC brand/type lol.

 

So that’s about 2/3rds of the TT gain for the SC. I had originally planned on the SC for simplicity and price, and perhaps a bit more durability. Not sure what I’ll do now with the large difference in performance and limited difference in price.

 

Any numbers yet on the 10psi pull from Saturday?

 

that 5.0 vs. the 5.7 is similar to the 3.5 vs the 4.0. more power, less torque. More power at high RPM's. It's really the only complaint about that engine... RCF / GSF owners complain about low end torque (just like we complain about that with a 3.5).

 

Yep, these are my exact thoughts, price difference makes it a bit difficult.

Although some people including me are not mechanical inclined so Turbo installation could incur much higher costs due to labor than the simple bolt on SC... Something to keep in mind.

I see, this could be a valid reason but if Toyota wanted to, I bet they could lower the HP, extract a couple more torque and move it downlow.

Hell Matt did something similar with the 3.5

 

Bro. Man.... stop taking these knuckleheads here so seriously. You have the most insightful posts on the 3rd gen forum.

Shit talkers, haters and complainers are just part of interacting with communities online. It’s sadly a part of life in 2019.

You have way more fans here than detractors.

Never mind. Gifs are a pain to post.

 

I’m definitely in the ‘what to do’ camp now. My need is scheduled for ~2 years from now when we get a decent sized travel trailer. I don’t off-road much at all, so am not concerned about clearance, though the water crossing issue is a bit of a concern given that flooding in Texas can put routine water crossings at 1-2 feet when bad, and some at 2-3. This is my DD, and my weekender would be a disaster in high water.

Would the SC at 6.5 psi be ‘harder’ on the engine than the TT at 5.0 psi? I don’t know.... what is the average psi boost in each scenario based on my driving style? What matters most... integral positive boost over time, or is it non linear with increase? Would there be an SC controller that I could dial the boost up and down on. Honesty, I’m pretty happy with the performance and mileage on OVTune 93 perf. So if I could have boost at 3 during normal driving conditions and easily dial up to 6.5 when towing, that would be great.

I’m all about plug and play and reliability when available. When I lift, it’s going to be Billies at 1-1.5” for simplicity and swap out rather than rebuild.

I’m still likely to go SC route just to minimize maintenance and maximize simplicity/durability. Another 100HP is still a 36% increase in power. And that’s not insignificant.

Toyota says my truck’s good for 6400 lbs towing/cargo. That means their engineers have determined that the drivetrain and frame can handle the weight. I plan on a dry weight of ~4300 lbs, so figure 5500-5750 fully loaded by the time you add cargo and passengers. That’s still under the limit, but the experience is likely to be lacking. I just want the added performance so the long distance commute isn’t so stressful.

And heck, who doesn’t enjoy a little day to day performance. I had planned on adding the magnuson SC to my FJ when it came time, but I was getting darn close to 200k miles on it and I was getting a bit worried about using it as a tow vehicle. Plus, its weight limit was 5000 lbs, im not exactly sure why; perhaps a bit of wheelbase concern? But the 4Runner is the same so????

So back to the SC vs TT debate...

I’m likely to do the install myself (with my gear head son-in-law), so the SC is more attractive there.

I want the engine to last as long as possible, so SC has a slight edge over TT there?

Power, the TT clearly has the edge there with even the 5psi tune surpassing the the 6.5psi SC.

Cost, at these price points the SC and base TT are essentially the same price, or near enough to not influence the decision.

I’m getting the sense that all the peripherals for the TT might add up to a price differential worth considering.

And finally, we don’t have any curves yet for the SC. Peak HP doesn’t usually mean too much for me in a truck platform. (It does in my weekender, but that’s a different need). What matters to me is the 2000-5000 rpm range... that’s the normal range for cruising. 2k when at speed, and 4500-5000 when accelerating/passing. 800-1500 doesn’t matter so much to me either. Yes, it would be nice to pull hard from the stop sign, but even pulling hard is still gonna be slow when fully loaded.

Hmmm, we seem to have a bit of a run on post here.

Anyhoo, sometimes it’s helpful to ‘talk it out’ and I think I’m now back solidly in the SC camp for the same reasons I was initially. It was just those darn great TT performance numbers that made the SC seem to be the lesser choice. I got distracted by the eye candy but am now back on course. At least I am until I do some more research and find a “yeah, but what about....” that squirrels me again.

 

I hate to bust your bubble but your Tacoma won't pull a 5,500lbs TT. The truck runs out of payload well before you can reach the rated 6,400lbs towing capacity. For example I tow a TT that is around 4,800lbs loaded and with just my wife and I, a 11lbs pup and a 100lbs generator in the bed in just under my payload by only 40lbs.

 

I’ll have to do the math again of course, but dry weight of 4300 leaves 2100 lbs for cargo and other ‘crap’. I know it adds up fast, but I’m figuring on ~500 lbs of margin. Perhaps I’m misjudging the amount of add on crap.

 

Sure it will run on 87, but just like the ecoboost engines, you’ll loose a dramatic amount of HP and TQ when using 87 vs 91 (at alt)or 93 (sea level). The engine simply can’t take the ignition timing you can give it on premium, without detonating when using 85/87 octane fuel. Of course, this is possible due to advances in fuel and ignition strategies with modern ECUs.

 

Max payload of the Tacoma is 1,175lbs. A trailer with a weight of 5,550lbs will have a tongue weight of around 600lbs. Cargo of two adults (350lbs), a dog or child (100lbs) and your already at 1,050lbs without anything the bed. If you have a hard tonneau cover and some cargo in the bed you will be over your max payload.

Valid points to consider, and perhaps my intent for airbags and a weight distributing hitch might not mitigate the concern as much as I thought. Rather than continue the discussion here, I'll head over to the towing threads and post any further questions there.
