Supercharger effects on MPG

[Pedaldude]

I was referring more to the entire SC setup haha

The supercharger whine would probably drive you crazy too.

Not to mention dudes starting small talk at the gas station!

Almost forgot all the little kids and teenagers doing the universal burnout finger gesture.

You just have to move the decimal two places to the right, easy.

The transmission whine is louder so no one even knows lol.

Literally everyone on the forum.

Starsky and Hutch....

Maybe the moderator can rename this thread to Superchargers 101...

Seriously, I appreciate all the knowledge. There is so much misleading/misinformation, let alone the burn out/take-off videos, I don't know what to think. Let's say I purchased the Whipple kit. I'm pretty good in the garage, around engines, tools, OCD gets in the way, etc, is it difficult to install? Seems like getting around to the backside of the intake, up against the firewall would be tricky. Then lowering/wiggling/positioning the SC would make me uneasy banging it around into position.... I imagine a tech would fight with it too, but I wouldn't know about it

FYI: the Whipple TB has a terrible squeal, you can search my handle for the post.

Heres the instruction guide to the Roush kit. If I do end up going power adder, this will be the kit I go with.

I did mine by myself in the garage in 2 days, I ran into some things but sorted it pretty quickly. You are correct the lower intake back bolts suck a fat dick but the uppers are pretty easy. The rear passenger spark plugs suck too.

Trip I did Monday

21mpg supercharged! Sweet.

Any particular reason why Roush vs Whipple / Ford Performance?

I read over the instructions and it looks like the Roush kit is a bit more involved than the Whipple?

It looks like the Roush kit uses the factory fuel injectors. I thought there was something about having to run richer, hence the larger injectors in the Whipple kit?

I thought I read somewhere one or all of the kits replace the harmonic balancer to address engine/crank vibrations issues?

So confused

It is more involved, but the throttle body issue alone with the Whipple is steering me away from that. The Ford Performance/Whipple kit uses the stock TB, so it is likely just fine.

The Stage 1 Whipple and the Ford Performance/Whipple kit also use the stock injectors. Means they are leaning more on the Direct Injection side in the calibration. I do like that Roush includes a fuel pump voltage booster as added insurance.

To my knowledge, Roush is the only one who is changing the crank pulley/balancer as they did not like the harmonics otherwise.

Thanks @93dpscoupe , see, it's things like this that make you ask why even more....

Is a "Stage 2" kit better because it includes larger injectors, it seems like it would, but maybe it's a band-aid for something.

Does "leaning more on the DI" mean allowing more fuel to compensate for lean conditions?

Why does Roush include a FPVB and Whipple doesn't. What does it do in a SC configuration?

Again, I apologize for pestering folks with this stuff...

The stage 2 Whipple adds throttle body and injectors so you can tune in more fueling for more power as the tune for the stage 2 would max out the stock injectors hence the power difference between the kits.
Im not familiar with the roush kit but I imagine they replace the balancer to maybe give a bit of an underdrive? I replaced mine when I did my GT350 as I went to a 10rib setup and I went 20% underdrive.

As NavyChief said, Stage 2 has smaller pulley and different TB and makes more boost/power, so the injectors needed the upgrade to compensate.

Yes. Instead of using the port injectors as the entire enrichment plan, they are actually tuning the Direct Injection system to add the enrichment first.

The Voltage booster does exactly what it implies, ramps up the voltage to the factory fuel pump, overdriving it so to speak to supply more fuel. Some say this kills the pump. I've had a customer with a turbo 2015 Mustang with a booster set to max for 8 years now. Still on the stock pump and the car gets driven hard, as it should be.

I want a supercharger now.
