Just keep in mind that you will lose torque when you do. 3 inches on a N/A car does that. You are removing the back pressure by having a larger exhaust and thus killing your torque output. Not the same case when you have a turbo setup cause the turbo needs to flow and hates back pressure.

Oh yeah man I know, and its gonna be stupid loud, but its gonna be okay because shortly after a turbo will be on it too :happy0180:

That is completely untrue and a very old myth. It is very well know that a 3" exhaust on an N/A 4 cyl does in fact NOT lose power or torque. If anything, you gain both of those all across the power band. Most N/A Hondas are running 3" systems that gain more power than their 2.5" counter parts. Just ask Fullblown about how much better S2K's run with 3" systems.

yes

Red = 91 pump @ 7psi
Green = e85 @ 10psi

What about a orange entry for 93 pump @ 10psi.

What would be the highest boost you want take it to on 93?

I'm honestly surprised the motors are holding up with 8 psi on 93. Does the DI help with being able to run more boost with higher compression?

That is a big reason

Huh???

At stock compression on a K series 11:1 I made 425whp at 16psi on 93 and drove it that way for three years beating the piss out of it. I only ended up building internals for fun later on. I never had any issues with the motor. I'm sure the 86's high compression Subaru motor can handle 8 psi. And incidentally, high compression makes the HP numbers easier to hit.

Well the rule of thumb that ive been lead to believe is low comp = high boost, high comp = low boost. High boost and high comp will always give more power, but you will need more octane than 93.

Correct, that is why they are able to run more power with this kit on E85.

It's because the higher the octane rating of a fuel, the more compression that fuel can withstand before detonating.

8-10 psi isnt high boost, but it is with 12.5:1 cr on 93 with oem internals. Im not misinformed in the slightest. People bashing others is just as harmful as this accused " misinformation"
