Supercharger: Yes or No? Opinions?

I'm loving mine but I've F'd with it

@SeaWheezl you run the larger Pistons from Toyota take it to 4.6, port polish the head. I don't remember the exact numbers as far as torque and hp but it was worth it cause your already there. If you have piston slap or the block is thrashed some you'll have to step up any ways

Eh, I have run washer fluid on multiple turbo cars with water meth injection and zero issues. You just need to pick up the jug and shake it and make sure it doesn't foam up, or they used extra cleaners/soaps in it. Always try and get the -20 degree not the 0 or +20.

Not sure how in the world the washer fluid could gum up your SC as it should be injected post SC'er.

And I have mentioned it multiple times you are not using water/meth in this application for any performance gain and to do so would be foolish. The people that use water meth for performance gain and push timing because they have extra knock protection risk killing the engine if they run the system dry, a pump fails, etc. The system should ONLY be used as an extra safety method to keep from detonating in high heats and high loads since the TRD Superchargers are not properly intercooled.....

I'm all over northern California and the Sierras. I have an SC with meth injection. Also regeared to 4.88s with 35" tires.

The good news: it hauls ass compared to regular FJ/FJZ80s. It will do 95 on a flat highway if there's no wind and the temp is low.

The bad news: I'm having real world issues with overheating and having my timing pulled. Climbing Donner Pass means it'll pass the 18 wheel rigs but does slog down still on the steeper inclines. In the dead of summer I really have to watch out, as I had the timing pushed out to the limit and dropped the pulley size way down. It was throwing dets until I backed off on the timing. Also ran into the issue of over pressurizing my crankcase and blew the dipstick into the hood insulation (and spewed black smoke out the exhaust pipe) halfway up to Tahoe in July. Good times. I also think the SC *may* be overpowering my fuel pump.

Fast forward to now... I strongly recommend getting an IC and a snorkel. That's where I'm going next to deal with the temperature issues. Also, if you do decide to go meth, do NOT use windshield washer fluid unless you like to have blue-green scum gumming up your SC, intake, and everything else. Go with straight meth that you can buy at a race fuel outlet. Other items on my to-do list include replacing the fuel pump and the fuel injectors. Already did the fuel filter. Been having issues with mild hesitation on hills between 2 to 3k RPMs.

PS- I've never actually overheated due to the SC. What happens is my power disappears on inclines in the summer as my timing is pulled thanks to the heat.

PPS- I've seen absolutely ZERO change in performance with the meth kit and regret getting it in the first place. I think the only thing it has helped with is to keep my engine from detonating because I'm running 7 PSI with a smaller pulley along with advanced timing. Advanced timing that gets yanked by the ECU when the engine gets too hot in the summertime...

I feel like I'm talking in circles.
