My explination is terrible, because im basing of my own expierence.

anyone remember my consistant 14 sec passes in my civic (yes, slow)
-bald...well shredded street tires, an exploded driver side motor mount, blown struts all around, and full interior.

with the skunk2 intake mani on, it droped to consistant 15 sec passes. With a higher trap speed, and slower 1/8 mile. this was with street radials, new omnipower coilovers, new motor mounts with inserts from kyle, and a few other things.

Thats my explination. I dont like them, they are sweet noise makers....thats about it.

boost vs na is completely different in the optimal intake design...... as i am guessing that civic was just motor

I dont know much about e85.

Thats why i said on a race head, pump, and a 2.3.

Yeah, it's usually something roughly around 30% more fuel needed for the same power with E85.

BTW, I wasn't trying to be a dick in my previous post lol

No, that just comes natural.

your guess was right.

which is why i stated my explination is a terrible explination.....and i hate buschur.

I would like to see a factory boost intake manifold flow test (evo, gst, tsi...the tt gen s4), against and aftermarket intake mani flow test of the same application. just to see.

realistically, a more free flow design would be optimal, but i wanna see what it looks like under real load.

Its cool,

I was just figuring from injector size.

1000cc pump vs 1000cc e85 is something i dont know enough about to compare via fuel charateristics.

im betting its like comparing c16 against q16.

(stuff you guys probably already know)
The reason you need about 30% more fuel capacity on E85 is because stoichometric combustion for E85 is around 10:1 [10 parts air to 1 part fuel], wheras it is the familiar 14.7:1 for gasoline.

spark-fired engines control the amount of air input [via the throttle], and then add the right amount of fuel for the desired combustion. When the fuel is E85, you simply need more gas for the amout of air you've let in.

For a given conversion application, the injectors, lines, pressure regulator, and pump(s) are all things that might need to be upgraded, depending on where there is headroom in the existing system.

I've got some questions Kevin: Do you have or need an upgraded radiator? Does the evo have any oil starvation problems at higher g sustained cornering? Are the brakes, lines, etc. all stock?

Brake cooling ducts are an outstanding idea besides pads, fluid, lines, and removal of the brake dust covers (if it has them). One problem sti's have is flex in the firewall under hard braking at the brake master cylinder location and a master cylinder brace reportedly helps in pedal feel greatly. Thought I would mention this as it might be similar on the evo.

Other than a brake makeover get every upgradable suspension and drive line bushing you feel comfortabe in changing out. If any of this is presumptuous I apologize, been geeking out a lot on this stuff lately. Any plans for big weight reduction or a cage? Suppose that depends on how much fun you have this summer huh?

Personally if it were me i'd buy the basics that you still need (brakes, tires) run a few races get a feel for how it handles and were it needs improvements and work from there. It's gonna be a lot more difficult to sort out if you've changed everything.

Best recommendation I have read in this thread. An EVO or STi stock is too much of a car in stock form for 99% of owners. Drive the car to IT'S limits, then see where it fails you. Before you can drive it to it's limits (in control), a person has a lot of education/seat time.

1. Brakes
2. Minor Suspension/alignment
3. Tires
4. Drive it

I completely agree with that one Jason!! I wish I could have started out doing auto-x with my 240 mostly stock in stead of jumping into it and trying to learn in a fully built car.
