Magnuson supercharger install here at down east offroad

Yeah, and stock HP numbers at the flywheel are actually about 50 HP less than what is actually advertised due to parasitic drivetrain loss so figure you guys are making something in the neighborhood of 228 HP in all actuality. 227.96HP if you have a 18% drivetrain loss in fact. So you are actually doing better than stock with the blower on and then some. I'd that's still not enough for you, mod it and make pony power for way cheaper than what it costs to mod an NA engine and get power from it. I've managed to get about 114HP additional from my MP90 to the ground and if I can do that out of the old school roots you guys can definitely do that with the new TVS.

I'll tell you right now though. 300+ rear wheel HP out of a sub 5000lb truck scoots you along plenty nicely as far as passing power and general power as a whole goes. It's nice being in V8 territory.

About 18-19% to be exact.

By no means. The engine is. Lol.

 

Just saw the TCMBST install video. I get that he had heavy tires/truck but man the truck only made 275hp on the dyno and 231 lb/ft of torque. That’s significant power lost to the wheels compared to the new advertised numbers. They now advertise 373hp/332tq at the crank. That’s about 100hp And 100tq loss to the wheels! That’s insane. And I get that he does have a heavy rig, so that needs to be considered but I’d think most of us considering a SC also run bigger tires then stock.

Compared to the 2nd gen SC, they advertise 305hp/335tq but their dynos showed 289hp/291tq at the wheels. Very little loss compared to the “new and improved” 3rd gen SC.

And in stock format, the Magnuson employee in the video they say the dynos usually show around 230hp to the wheels for Tacoma’s on stock tires. From a stock truck of 278hp, that’s only around a 40hp loss.

For being an entirely new and better system then the older SC, it sure does give away A LOT of what it claims. And don’t get me started that they advertised 50% increase for months on their website.

I really hope they post a video comparison with a stock or lightly modded truck and it shows MUCH better numbers.

 

We don’t really know how the 2GR-FKS will flow under boost. But I don’t think the 500mark is out of reach. The exige which has the same engine is in the mid 400’s. LS500(3.5) low 400’s. The question is what the weakest link is...
guess we will find out once people start cranking it up

 

Has anyone found a breakdown between the Lotus engine changes over a standard Camry unit? As someone who's used boost to put a cigar size hole through my piston I would love to know if we need J&E forged pistons etc...

 

Nothing is the same. Lotus uses older 2GR-FE. 2GR-FKS is superior in every way according to the engine references.

 

He's on 35s so yes that is going to be about right and like everything it all depends on the dyno, day, and correction calculations used. For reference the big rock bouncers a few are putting our 1600+ HP at the crank put them on the chassis dyno on 43" stickies and they don't/or barely break the 1000hp mark. Typically the 1000hp crank guys are dynoing around 500-600. Putting big #s down is fun at shows for the competition but dynos true form is used for tuning and seeing what gains are achieved and where.

 

I didn't think HP even had anything for the 3rd gens yet. I was under the impression you were/are the only name in town really for tuning the 3rd gens.

 

I don't mean the actual engine. I am referring to all the hardware attached to it. Historically speaking the exhaust will be on the 3rd gens because they literally use the exact same Y pipe on the 2GR as they do the 1GR, and that setup is in NO way rated for even 250 wheel horsepower. The rest of the exhaust creates restrictions as well so moving forward on the topic, when I say the engine, I mean the entire setup as a whole including all attached hardware to make it federally ARB compliant. Lol.

 

This has not been my experience ever since Denver Metro fell under the emission requirements. They open the hood and do a visual, check under for cats and exhaust pipe status, do a pressure leak test on the gas cap, run it on the simulator - every time it has gone to the Clean Air Colorado stationary building. Road-side is another story - sure you are good as long as you have it done within the required window - F' that up or miss the window you have to go to the stationary building for the test. Not sure where you go in the Denver Metro area but let me know. Perhaps your address is not in the emission requirement zone - which is nearly at my back door - but not for me. ???

 

My state does similar but as far as aftermarket parts they could care less if it has the Cali stamp of approval with CARB or not as long as the vehicle has the emissions equipment it came with from the factory and it "appears" to be in working order then you are good to go. CARB is really only necessity in Cali where anything added that does not have that approval and the sticker then fails their emissions testing. Now if CO adopts that same requirement then I can see it being a necessity.

 

In addition to the fuel wall, I also suspect Magnuson might be trying to stay under whatever the torque rating is for the transmission.

 

Typically I go to Adams County. I am gonna take mine to a facility after turbo install and run it and see what happens. Worst case scenario I have 3 years to move out of the metro area. In my experience all of my vehicles have only ever been idled and passed. No visual or anything. All are 4x4. Regardless carb only means you have a sticker which colorado does not require. I live probably less than 15 mins from you.

 

??? well I know how to find out. I'm going to go the the emission station and ask them. I will report back. Could be it is not necessary - that would make my day! Thanks for the input.

 

Oh yeah for sure. Supporting mods are a must. From intake to exhaust and everything in between. Luckily I have 3" back so flow won't be an issue. We'll see as I am trying to hit that magical **500** number

 

I wouldn't ask I'd just look up the actual GS law and see that way if the emissions station tries to give you some run around you know the GS so that you can point them to it. I know stations around here try and do that mess here so it's best to actually know the law vs ask someone that may misrepresent what it actually states.

 

Crank I assume?

 

I imagine it's detuned since they offer a warranty.

 

Yeah. I’m on heavy ass 37’s. So 375-400 WHP is the goal.

 

Thanks for posting the link to the compressor map.

Everyone keeps comparing PSI to PSI but it doesn't work that way. Sure this supercharger can max out at 35psi but it's efficiency is not good. If you want to really push that kind of power, you need a larger compressor.

The "base turbo" that @OVTune is offering will go up to 53psi but it's too small to flow enough air on the tacoma to ever reach it. Funny enough the efficient even at 53psi is still better than the r1900 at 35psi. Mat can chime in if I'm wrong. I think what he meant by the base kit being limited to 15psi is not a physical limit but a realistic limit of what he designed the kit for. Good low end response and reliability.

Before anyone says I'm being an ovtune fanboy, look at my posts about 2.0 and turbo kits. I've been very critical about both.

 

He needs to rebrand. I know he tried to distance himself from the MOAB incident but I can't seem to forget about it.
