I'll second that. I just had a Paxton centrifugal at 10 psi (with a restrictor plate) a set of headers and a fuel pump. That car felt FAST. It was impossible not to chuckle after a pull.

An NA car needs a ton of motor to replicate that sensation.

Last car I had was 7 years ago, LS stuff. I'm just learning more about this LT stuff.

Yes, it's freaking awesome and the smell of E85 tells people don't screw with this car.

Sorry. I am completely lost on this topic. I asked earlier about fuel and everyone said nothing less than 93 octane. Now I’m reading E85 for more power. So which is it

Ethanol itself has an octane rating of ~100, so the more of it you mix into regular fuel, the better knock resistance (and cooling effect) you get.

The Camaro isn't equipped with all the hardware necessary for E85 fueling (meaning at least 50% and up to 85% ethanol) from the factory, but it's a relatively cheap upgrade that helps in every way except fuel economy (which people interested in making power don't tend to care about).

Thank you

It worked for me. I suppose

HEY! I am stock and my 15.3mpg is what I was aiming for ,I care about MPG.

This sounds bad ass to me

So just to confirm, you guys with the forced induction have to run E85 100% of the time?

I’m learning, seeing some of the FI setups and I’m amazed particularly at yours.
I want that kind of power and I may end up going FI

No you can run 93 octane on the street no problem. There’s much better power and better engine lifespan under boost running E, that’s all.

The Coyote is strong. However, no issues at 700-750 rwhp is not remotely true. I personally know or have known 6 Coyote owners who have 700+ rwhp in the last couple of years; 5 of them have had to rebuild transmissions after breaking them on the street (not launching at a drag strip). Mostly A10s, but also M6 and A6. So, it’s not an unbreakable drivetrain, nor “set it and forget it” with a supercharger. The one that hasn’t rebuilt only roll races on the street, and he only had it boosted for like 6 months then put it back to stock and sold it.

Also, the ring gap isn’t set for boost so you can’t do long pulls without seriously risking the engine.

That said, boost a Coyote to 750 with extreme caution on the rest of the drivetrain.

I’d say if you’re that concerned with it use that blower money as a down payment on a ZL1. If that’s not feasible then a big blower low boost application where you run around 600 rwhp seems like a nice compromise, but I think you’d need the LT4 fuel system. For what it’s worth GM upgraded the crank for the LT4 because under extreme conditions in their torture testing they were breaking LT1 cranks at ZL1 power levels (650 hp / 650 tq). Also, GM upgraded many components in the LT4 besides the typical crank/rods/pistons. Even the heads are a different material and constructed differently to handle the higher cylinder pressures of a boosted application.

In hindsight, I sometimes think that going ZL1 would have been much more cost effective long term if I decide to go boost.

Can someone explain this to me like i'm 5 ???
