Supercharger is installed!

Well last nite i put in my Supercharger, Easy peasy!
I bought a universal a piller pod holder and put my boost gauge in there,
also put a cheapo catch can in and the colder denso plugs.
Seems to run good! no issues whatso ever other then the SC belt seems to ride towards one side of the pulley?
I also did a coolant flush and installed the colder stant thermostat.
The tranny kick down cable is extremly tight!
Anyone got pictures of how you made your engine bay look a little nicer? i wanna reroute some of these hoses.
It sure seems to pull harder and i love the sound!

 

Here is how I have stuff routed under my hood. Enjoy your blower!

 

damn thats nice!
everything looks similiar . Your kickdown cable isnt as tight?
i need a fan schroud!

 

Well everything g seems to run ok but one issue, at about 1800-2000 rpm if I'm crusing all the sudden it will loose power for a split second... Just bahhh and then go back to normal. That's the only issue.

 

i could probably remove that silencer and plug it with something eh?

ANYWAYS!!! i was having some driveability issues. It would not make any power. it would barely do 110km/hr on the highway it just felt like it was powering out!
So i looked it over. Found a vacume hose had come right off. well it was split. so i fixed that. figured that was the problem. drove it some more and it still felt like it had no power compared to the first nite i drove it with the SC.
So anyways i was looking it over and found that this block off plate had a bolt missing and was just dangling there.

So i took it off found a new bolt put it back on with locktite.... took it for a drive and it was idling rough and still had no power? so this morning i run the codes...P0171 and P0174. Lean!!!
Anyways upon looking it over. i put that block off plate back on upside down!!!! so i fixed that hopefully it makes everything work better. I have never cleaned the maf. Any at home products i could use on it? i dont have maf cleaner. i do have electrical contact cleaner thou?

 

You need lights!

 

That would be nice! I cleaned the man. First time in 150k lol! It was pretty dirty!

 

well it seems to be running fine now. Not 100% sure. idle is normal. feels like more power. highway speeds arent an issue but i just got home to check codes. (no cel for some reason) and it says p0330 knock sensor circuit malfunction????

 

ok what wires do i tap into to splice this knock sensor into the other one? anyone know?

 

Did you give her any other upgrades when you installed the supercharger? Bigger injectors, fuel pump, and a piggyback ECU. I'm suspecting that's why your knock sensor is pissed off if your running lean. You'll definitely want a wideband air/fuel guage to keep an eye on that!

I'm not exactly an expert on this and there's plenty of guys who've run their SC for a long time without these upgrades, myself included... I've been dealing with knock/ping in my engine though with the supercharger. Bottom line seems to be you need to do some upgrades to deal with the increased fuel demand for the supercharger.

I was looking at the 7th injector kit from underdog racing but I've already upgraded my stock injectors so that wont work for me. There are plenty of other piggyback units that can work though, uni chip and a few others I'm not remembering.

 

The thing is i dont hear any knock and im running premium and its -25 celcius here .
i have a meth injection kit waiting to be installed. BTW im running the stock pulley.
i have the colder plugs, colder thermostat and a koolblue drop in filter

 

Well i seem to be getting really good mileage. What are my cheapest options for the knock?
i have a meth injection kit that i didnt install yet.

 

Yeah I usually only hear knock when its hot outside and I've been driving the truck awhile and in higher boost, it gets worse at higher elevations for sure. Definitely only run premium. As far as cheapest options, well nothings cheap. But from my research the 7th injector kit from underdog racing is your best bet economically if you still have stock injectors. Also the most plug n' play. I wish I'd known about that before I upgraded my injectors Now I'm looking at a custom ECU and lots of tweaking. That kit comes with everything you need, the 7th injector puts fuel directly into your supercharger and the ECU is already tuned for the 3.4L 5VZ engine.

I don't know anything about methane injection but I would wait to install that kit or upgrade the pully until you get the truck tuned.

 

Def recommend getting the 7th injector kit. It'll run better and you'll get even more power. I'll be buying the kit before I put my supercharger on. That's the main reason it hasen't gone on yet, I keep spending money on other things.

 

I haven't researched the Toyota SC much beyond pricing, but I do have a boosted VW. When running more boost than stock a tune(r) is needed. I went from 10psi stock, to now 23psi on a BT, I need more fueling. I need more to accompany the increased airflow and I need more fuel pressure to over power the additional 13psi. Make sense? So I've stepped up from a 3bar fuel system to a 4bar fuel system as well as bigger injectors. (43 to 58psi, for those that need it translated.)

So, with that tidbit said and hopefully explained enough to get your head wrapped around it. Wouldn't it be prudent to increase the fuel pressure along with a 7th injector/bigger injectors? You're basically going from a vacuum to 8-10psi. Right? Mine will run run -30 in/hg when off throttle engine braking. Which is almost -15psi. So, again, basically by boosting a NA engine to 10psi, you're now needing to overcome a 25psi increase of air pressure. Right?

Please correct me if any of this is incorrect as I'm also interested in boosting my 2.7l. But if it happens, it'll be on a turbo and not a SC. I'd rather do it a way that I already know.

 

As for water/methanol injection, it's the way to go with a turbo. A SC is a little different. With my BT car, I spray it after the intercooler and ahead of the throttle body. The charge air insanely drops about 40-60*, depending on ambient temps. But a roots style SC is basically the intake manifold. So spraying it would have to be upstream of the higher pressure. Also, with the roots type it's a double whammy; heat from pressurizing the air and hear from friction of the screws.

 

Well dont they run these superchargers on stock motors all the time?
I will buy the 7th kit soon.
I got the code p0330 and p0420 today. Does that 0330 put the motor in limp mode or someshing. It seems to have no power

 

That's floored

 

Well yeah, but that doesn't mean they run well! The stock components are just not really capable of delivering the increased fuel demands and the stock ECU is not able compute the proper ignition timing or the air/fuel ratio when in boost. The risk of damaging your engine is much greater. I don't get any engine codes running mine though, and I definitely get plenty of power in boost. So I'd work on diagnosing/fixing whatever problems are causing those codes to pop up. It could just be your sensors, if the knock sensor is malfunctioning I do believe a symptom could be a loss of power as the ECU tries to retard the timing and alter the air/fuel ratio. Get that fixed asap!

 

im almost ready to take it off and sell it honestly
