Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I go on trips often to nevada. Elevation 7000ft+ i should have some good feedback for ya.

 

Forced induction helps the engine in higher elevations because you're putting more air in than a naturally aspirated engine can dream of at a high elevation. It's the reason why they used to put superchargers on fighter planes like the spitfire

 

Turbos struggle at significantly high elevation, especially if you were custom tuned nearer to sea level. FI loves cool, dense air, and air is thinner up higher

 

Do automotive turbos not work like aviation turbos? In turbocharged piston airplanes, they’re specifically installed to maintain sea level horsepower at much higher altitudes.

 

I'm no engineer, so I'm not going to pretend to have an answer for that question. But I know from personal experience too that automotive turbos love denser air. My ms3 targeted 29psi on 33% e85 using a gtx3076r and struggle-bussed HARD at 8k ft in Cloudcroft, AZ. My buddy with a BNRs4 (somewhat similar in size to a gtx30 series) lives at 6500ft and with the same tuner working the magic, could only target 24psi max I believe because of the thinner air. I also remember the TFL Truck guys comparing the gen1 and gen2 raptors at aome ridiculously high elevation trail and remarking on if they think the TT ecoboost would be needing to work harder

 

Turbos at higher altitude give you more power over NA (obviously), you'll lose more power NA than you'll lose with turbos up there.

For instance a 600HP NA (at sea level) vs a 600HP turbo (at sea level) the turbo will retain far more power than the NA up at 8k feet.

 

Well, yes, you get your bump in power, but that doesn't mean that turbos don't struggle in thinner air

 

This TT is going to give us 600HP!

 

Next rumor I'm spreading!!

 

Oh they do, they just lose less than an NA engine up there

 

The OVTurbo thread is going to be so much fun

 

Just downloaded the new flash manager and tuned to 1.05 truck feels great, what do you guys think so far?

 

It's not April Fool's...

 

I honestly prefer the stock tune over 1.05, 1.05 was a total let down

 

Everything struggles at high elevation which is exactly why planes and helicopters have fine they don't struggle too much

 

What if mat just does a quiet release of 1.05 and tells nobody so the links and everything will be sitting on the first page unnoticed

 

Already been checking that page.... and down below to see if he is on the thread. he is!

 

About an hour ago, his profile says he was here an hour ago

 

I just flashed to 1.05 its so fast im not buying turbos >_>
