Well Im at 12:1cr n/a but Ive ran with and beaten FI cars with up to 200+rwhp than me. So, idk...... Btw, new Ferraris are 12:1-3cr n/a as well. We might see more companies go with higher compressions and run their cars leaner to gain more mpg's. Thats what they do with the flex fuel cars. When filled with e85 they run scary lean but thats how they try to get better gas mileage to help you forget that you need 30% more fuel.

That's interesting. If they have 200+rwhp more at similar weights they should walk you. Heat soak is a bitch though...

Yes Ben, you have an amazing motor. I wasn't saying that sarcastically, as in, no NA motors don't make more linear power curves.

I was saying that sarcastically, as in, ya, maybe the power curves are more linear, but who really gives a shit? Who is sitting behind the wheel thinking... ah, what a nice linear pull this is. This is way more important to me than having another 40% more horsepower.


Be careful with your response Mr.Magnacharger.

I think Sean's original post had more to do with given increasing requirements in fuel standards inevitably meaning more smaller FI engines and I think he's basically right. As for cost effective power, or shear raw power, obviously there's no comparison, FI all the way. I'm not opposed, at some point I'll definitely have an FI something. But a great NA motor is, well, something special. I for one do love the linear power band. So does Gordon Murray, which is why he hasn't used FI in his rather super super cars. Though to be fair, modern smallish turbo systems don't really have much lag and are pretty linear; in a sense, just an effective emulation of a larger displacement NA motor.

It not just the FI, but combining FI with direct injection which is allowing high compression is spurring the development of these engines. The EcoBoost have 11 to 1 compression and the direct injection is cooling the pre combustion temps greatly preventing detonation.
