Turbo Charging A Tundra!

Dragy

just post the dragy



all these number are very well laid out.
Let's see the rubber meet the road....so to speak.

 

I'm happy to update the spreadsheet once I have the injectors and pump, but I'm certainly not a Dragy time pro. Heck, my times are still improving with my current setup which hasn't changed in months.

Maybe Jesse wants to lay down some times once we do the swap. 0-60 times aren't going to be our strong point, so matching a 4.6s time for the leaders board isn't realistic for my truck. The SC freaks of nature can hold those titles.

1/8th and 1/4 mile times and top speeds could be interesting.

 

< to be read with a calm tone, not meant to sound argumentative. just a discussion>


Good points.

I'll expound...if the Turbo is a performance upgrade, under which performance specs will it be judged?

and, what efforts have been made to demonstrate those specs?

us knuckleheads that use the S/C, are inquisitive to this wonderful addition to Tundras.

I am in no way doubting the efficacy of turbos...quite the opposite.

I want to see the numbers.



as to your last comment about 1/8,1/4 & top speed...I respectfully disagree.

Tundras are trucks.
at best, we are good for 0-60. maybe 1/8 mile.
we need to be powerful & reliable. This is why I admire/appreciate the towing data.

top speed is dangerous & largely unused.
1/4 mile stuff is dangerous too..too much stress on a stock block. and again, largely unused.

0-60? we do it every day.

 

Great question regarding the metrics. I will defer the educated and informed responses to Jesse @TurboKits

My personal thoughts: Dyno numbers don't lie, but I'm lost on how to accurately capture what I care about vs Dragy times. At baseline I don't think a single turbo is strongest in 0-60mph, but maybe I'll be proven wrong. Dragy also doesn't really afford a way to track my use case. Maybe Stage 2 and not having a 5k rpm governor will knock my socks off and put me down around 5.0s, but I don't believe I'm your huckleberry for 0-60 times. I'll absolutely give it a shot, though! I agree on top speed being silly, but I think it does capture the power throughout a prolonged pull, just like the 1/8 and 1/4 mile times would capture the same. IMO, they are more supportive of my use case since those prolonged pulls are me getting onto a highway and up to speed with the trailer. Open to ideas since I want to support the discussion until someone else comes along with a focus on the fun part of the pedal

 

We had been looking for the TRD Pro we just got for years. I did see a local Gen2.1 with a factory TRD SC on it and was tempted to get it and install the kit for twin charging and see what would happen. Maybe some day we can attempt it. I think the kit has a great chance of fitting with some tweaks to the piping! Would be a sick project tho.

 

Yes sir, we will get the data for sure... I agree, the truck is a 2/3/4th truck. 1st spins, unles you are hammering it in 4WD and at the top of 4th, I am going almost 120 MPH, which on a lifted Tundra with larger wider wheels is pretty sketchy. I think a 30-120 metric is good, the 0-60MPH, 1/8th and 1/4 are great numbers. I think the 1/4 will really only be attempted on a track for safely tho. We are up in northwestern CT and there aren't many 1/2 mile straight, flat roads and by the time you drive around to find one and then wait for no traffic. It's easier to take the 1hr+ trip to Lebanon and hit the track. But yes, we will get this data...

 

Thank you.

when you boil it down, at some point in time, a relatable comparison is warranted/needed/desired.

and, since the only 2 viable/genuine performance upgrades are S/C's & turbos.

I am sure there will be differences, clearly.

my expectations are that these variances will be small.

I reckon the 0-60 would be the common metric.



another variable to consider is the mystical 600hp (at crank) limit of these stock blocks.

I doubt 700hp on a stock block is "reliable". <Icarus syndrome.>

 

you know... @Silver17 is only down in PA, and @TurboKits is only up in CT... Just saying.

 

I'm in CT. More than happy to make a run to Lebanon with ya! I hit that track at least once a season (usually with my Camaro not my truck though) but have run the Tundra there once as well.

 

Now that we have proven the power, while being VERY conservative on things. We will 10000% be pushing the limits on the 2016 TRD Pro. To the point where we won't care if we blow it up, as we'll just build for more power. So the tests, trials and limits of our system will continue to be pushed...

Heck yeah, we'll reach out when ready!

 

Also the blower becomes the restriction we used to do this in the mustang cobra and ford lightning days.

 

I would love to see a twin charged setup on a built engine...
The dodge demon was twin charged awhile back. I worked on Detroit diesels 6v92ta's that were twin charged and just a cool setup. Programming is the key.

 

Yeah I think if we were ever to try something like a twin charged, Haltech or Motec would be the tuning choice.

 

So, from a practical standpoint, twin charged engine is possible?
I mean, I am sure the original transmission would go ka-boom so that needs a newer/super heavy duty one to work as well as fuel pump....
But wouldn't the two system fight against itself?

 

Up to a flow / restriction point, the 2 systems would work well together. After a certain point tho, they would fight eachother.

 

How far out is that delta in general?
I would imagine price is not practical for this to even exist that barely see any twin charged these days as well as the delta point basically null out the benefit of having a twin system?

 

The Dodge had to ,if I remember, time the flow of air for turbo and SC to work together. That was the hardest part.

 

Can't even guess without flow maps of both expected head units. It is more complex than ever needed and would really only be for fun, show, prove engineering prowess. But if straight power is all that you are after, turbo, build motor and trans, turn up boost. Don't over complicate the process.

 

I need a truck, not one that blows all caskets and transmission and can only go one round.....
Sorry for straying away from the main theme, let us return to that.....

 

Ha Ha, no worries, we own Tundras for the reliability of it all. So I agree, the hunt for HP is great, but making sure reliability isn't lost in the process is paramount.

 

Speaking of motec let's figure out a plug and play system lol

 

We can, we have connects with a company across the pond that does all sorts of Motec PnPs. They are expensive tho!

 

Was talking to some guys the other day about doing this, not on anything specific. They said what they do is use the blower for the instant torque and remove the lag, and once the turbo spools up there's a bypass valve so the turbo doesn't blow through the supercharger. They don't compound the power/boost, instead they are setup to be providing boost where they're both best used--supercharger at low rpm and the turbo at high rpm.

 

If we were to do it, I would try compounding 7-10 PSI and see what happens LOL

 

I mean, pretty spot on, right? lol.....

 

Build motor,,, build trans,, twin turbo!!!

 

That's what I want to see!
