General Supercharger Thread

I'm surprised it took you this long, as our highest altitude member I think you're the prime use case

 

I bet that White truck hauls it. that’ll be a fun ride.

 

Just call me "behind the curve" I guess .
I never planned to buy this truck. It all started with a search for a rear disc brake conversion kit for my 1st Gen Taco. Then I was always saying that the Tundra doesn't need a S/C, it has enough power. A chance encounter on Craig's List detoured that weak excuse. I am not in control....

 

Tunes done and the truck runs like a raped ape. New draggy times to follow. Thanks to @JustDSM with OTT for taking the time today.

I pieced together the stock box lid to fit for the idling and maf initial items and all worked out well.

New finding with the vented plate in the wheel well. Seeing cooler iat temps much closer to ambient. My theory is the cooler air from the stillen is staying on the box area better. Coming back from the coast I saw 6* above ambient. Which is a long way from where we started initially with this shit prospeed box.

 

Nice. Lucky you had your stock parts.

 

Dyno?

 

Oh I didn’t lol had to find one locally, luckily found a few on offerup and Craigslist.

 

No Dyno numbers but we will see what the draggy time says. Should give a good idea. 7k lbs, 37s etc.

 

Looks amazing, great work.

 

Before this last upgrade your numbers were flirting around the hp that most would go full engine rebuild with right?

Or were these changes and the switch to Whipple purely for a different power/torque curve?

 

I was on the stock pulley on the Magnuson blower. Reasoning on the switch was a bigger more efficient design with less maintenance than the maggy. I imagine the truck makes some where in the 620-640+ crank given the weight and times I've seen. Maybe 500+whp with 20% loss and my setup.

 

I know I'm not running the most power/boost here on the stock motor. lol

 

Less maintenance than the maggy? These are basically maintenance free. Even the guys at superchargers online say so. Replace the coupler with a heavy duty option and you're set.

Bigger and more efficient, yes, absolutely. But for what 20 hp over a stock mag? As stated before by @snivilous, they will all blow your stock engine the same.

 

Yea I'm not swapping a coupler once a year. Mine had an upgraded coupler from a rebuild and didn't make it a year.. Stock engine also yes. But this won't be a stock motor in the long wrong so planning for that. Hp isn't the full picture when doing builds.

 

I ordered a 77.5mm as well. I've read thru a bunch of the thread and I'm torn.

Not a Tundra, but a 3UR here. What is the threshold of safe vs pushing limits of internals, blown engine, or when engine life etc is sacrificed? Not going past 550whp?

I have a 2018 Lexus LX570 with the Harrop 2650 w/85mm-no tune, 37" tires, stock gearing w/8 speed. I live at 10,000ft. I'm installing either 80mm or 77.5mm pulley, walbro450, 775cc inj, prospeed fuel rail and pump jumper and getting a tune halfway across the country.

Keeping the intake, headers, exhaust stock and was told that made it okay to run the 77.5mm, but if had intake and headers w/77.5 it would make too much power for the stock internals. Is it pushing it that close to the limits of the engine? Thanks

 

At your elevation, you have nothing to worry about. I'm at 8,000ft and I'm having to overdrive (smaller pulley) the blower just to get to the stock equivalent HP here.

 

Got any pics of this beast?

 

all this elevation talk....I'm at ZERO elevation. LOL

Damn the torpedos, bring on the 77.5mm.

 

It’s pretty tame actually. Here it is with suspension in low, normal, and then high mode.

 

Damn, that is stuffed! Looks damn good!

 

God I wish the old lady would let me trade her rig in for one of these

 

Nice score. That is a sweet little truck!

 

Thanks, I love it so far.

 

Maybe @ViktorG can advise on the safe wheel hp lol. Hopefully its more than any of us are pushing lol

 

my lame excuse for the 77.5 is....I don't use much pedal.

~4500rpm's max. I reckon that will keep me under grenade level.


and I'm still driving a highlander....

hopefully get the truck back Thursday.

 

Some blow up at stock boost levels and others put out close to 600 whp with no issues.
Factors that will affect the outcome include tuning, fuel quality, water/meth injection use, ambient temperature, intercooler system performance, truck weight/load/tire size, towing, how aggressive is your daily driving, how long do you stay at WOT continuously etc etc.

 

@ViktorG don't want to go there again...unless ya got that built engine waiting.

 

Totally agree and what I was thinking.

 

What would you rather own out of the warranty period, a supercharged 5.7 or the new TTV6?
