OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

High pressure pump or low, or both?

 

The whole fuel system,
Low pump, high pump, DI and PI injectors.

Low fuel pump has 4 fuel pressure modes and at low pressure modes it leans on bank 2 (lack of pressure from fuel demand).

DI limits will be tested further. But this Is why larger injectors and a fuel pump are included with the powermax kit.

 

This is how I spec’d out my fuel tank/pump
Hoping it keeps up with your setup

 

I am ready to buy this kit

 

there’s a decent line up somewhat patiently waiting...

 

That's going to be one noisy fuel pump. Lol

 

With the interest more power had garnered, it makes me wonder why the TRD Pro isn't more like a Raptor.
Even if it was 10k more, people would line up to pay it if the Pro had 350+hp

 

Special edition trd pro with the 5.7L

 

I'd have to permanently tape my dick to my thigh if I could have a v8 in the 3GT lol

 

Probably so. But is there an offsetting penalty or fee or other financial disincentive for Toyota if their overall fleet mpg average goes down by 0.2mpg?

 

2x 525 lph trying to fuel a jet engine??



Minor set back. Injectors we received from FiveO are incorrect.

no worries, we have the correct ones overnighted to us. Might as well go bigger so we got some 650cc and we'll try some ethanol later
So, during this down time we will check plugs, compression, etc. Make sure all of our abuse is being taken well. Also going to take a moment this evening and dig through the fuel pump code, and see if we can stop the dynamic pressure changes and have it run a static high pressure.

I can say this, the pull we did yesterday up to about 3500 rpm (when we were out of fuel on bank 2) is making some serious torque

 

650cc should be plenty. Lol
What are stock injectors rated at? 300-350? Couldn't find anything online.

 

I run two Walbro 285's on my truck and I'm pushing way bigger turbos than the powermax. I agree with @OVTune that it's a bit overkill until he starts developing an EFR kit I think you'll be alright with a single 525 if that much is even needed

 

We will be running a single 340lph pump and that's already plenty.

 

Until there has been deposits put in place or Mat says he’s got a list going, I think it will be based on who has the money in hand and ready to “place in cart” first when it’s released.

 

I’m gonna hold off on this kit. I’m gonna put the money for this kit towards a new tundra when the next gen tundra comes out and hopefully mat will tune/modify the next gen tundra as well

 

I'm hoping that this will open doors for potential for a supercharger kit... especially rotrex. I'm not looking for max horsepower. Just something to give the truck some more low end torque for better towing.

 

Best thing for low end torque is going to be this twin turbo kit.

 

Might I add, I would be very surprised if a centrifugal supercharger could even touch what this twin turbo base kit will do for low end torque.

 

I was in the exact scenario as you a few weeks ago that it kept me up for weeks lol. The thought that ran thru my head went like this “hold out for twin turbo Tundra, or buy used 2014+ CM tundra and SC or buy 3rd Gen taco and get TT KIT” over and over again breakfast to dinner. Ended up pulling the trigger on the 3rd Gen so TT kit has to happen now, I cannot handle this gutless machine any longer. I secretly have a evil plan in mind if the new tundra kicks ass. Get the wife to fall in love with my taco, then I sell the wife’s 4Runner so she takes over the taco and I get a 2021+tundra
