The ethanol adds power, but the C16 reduces the fuel system requirements. It's just a balancing act where we set up the mixture to have the capability to hit the numbers we are after.

you want our cams for the larger fuel pump lobe. There is no point in trying to make a lot of power without it.

I don't see why not. I hit 612 on a cast wheel 259.

 

And that's what we'll find out

I can't even imagine trying to drive down the road in that car and give it some throttle... crazy.

 

Damn... i should upgrade to a 262... :p

How much for those S2 cams? Im holding off my cam purchase for some questions i had for you.



Oh and time to change your signature Matt!

 

I'm still wondering how much stronger the newer blocks are. The engineers are saying they are significantly stronger, especially the LUK, but that the third gen LHU and LAF are stronger than the LE5s by far.

 

Well, I'm not sure If I will be going that far. Would I be okay with just installing valvesprings if I want to rev out the engine to 7k with stock motor. Or you reccomend the cams.

 

got rid of the big boy turbo for a powerband turbo. won't sound as nice but it will definitely perform a hell of a lot better which is what we're after.

 

 

has that ever stopped you before? screw it.

 

Wouldn't running C16 pure have better gains than your experimental mix? Sounds like you're lowering the octane by mixing vs. running it pure. I would think eliminating the E would get you better results. Am I missing something here?

 

^ going by what Matt wrote and knowing it takes more Ethanol to run the same motor than regular petroleum. The ethanol makes more power, but the demand on the Fuel system is too much, so the C16 brings down the demand on the pump and injector cycle time

 

Yes but if the ethanol was eliminated, the octane would be higher and would not have to worry about the troubles of keeping up with the ethanol. I guess I doubt the ethanol can make more power than c16 alone is what I'm saying.

Am I wrong here?

 

E98 is 120 octane

 

Yea you are wrong in some regards. Ethanol has more properties to it then just the octane level. It has a slower, cooler burn and drops egts quite a bit as well. It has been documented and proven that E98 vs. c16 makes close to if not more than the c16 does. Issues with c16 are it is expensive, issues with e98 are it takes a whole bunch more of it than gasoline to make it work.

 

Okay yeah, I didn't know E98 had an octane rating that high. I understand the chemical properties of how it Burns and it's benefits. C16 acts quite similar.

Kinda makes you wonder why none of the AMS Alpha 10 or Omega cars run it. They are strictly C16 for the kill tune.

I still stand behind my claim that you could make more power on straight c16 given that you won't hit the fuel system limitations so it in effect should allow you to go further.....

 

I like the sound of the 259. It has a lot of whistle while driving around.

 

E98 is 115 octane, so the octane difference is minimal. Ethanol makes more power than gas, so we try to run as much ethanol as possible.

 

Yes, E makes more power than C16. It also has at least the same knock threshold based on our experience.

 

In our experience, ethanol makes more power than c16. We mixed them on Ryan's car went we went to 54psi boost and we made the most power by running as much ethanol as we could.

If you don't believe that ethanol makes more power than c16, try running c16 with your stock turbo. People are picking up 10% by going to E85. I am guessing you would gain almost nothing with C16.

I also forgot to mention as Cmiller said- C16 is $90 for 5 gallons. E98 is $20 for 5 gallons. Chase is paying less than that.

 

I find that interesting. More digging shal ensue.

Just for numbers sake, don't you think you could take the fuel system further with the C16 and achieve higher numbers or does the difference in power making ability not make that feasible? Like, running E and running out of fuel system is still gonna make more power than taking C16 all the way past where fuel system runs out on E?

Wow that's confusing...

 

I'd be happy with around the power Cmiller is making, but maybe I'll keep my LNF block...either that or use the core off of it to get your 5th injector kit and fuel pump after I get your Stage 2 Trans. Wondering if I moved my spare tire could I fit the block in that area when I come up for the trans! I'm shooting for the same power ScytheSnake's car has, going to have to buy a few drums of Ethanol though.

 

didnt think you guys ever tested the 2.4 to its full capability

 

I'm amazed everytime someone is confused about the fact that burning more fuel makes more power.

That said, Matt, your example should probably read:

5 gallons of c16 is $90
8 gallons of e98 is $32

lol

 

That aimed at me?

 

dyno video of my car with ryan's intake horn/no intake tube, officially requested.

here in OK 55gal-110=$437.25, 55gal-e98=280 to your door.

ridiculous cost difference for those guys running sat/sun weekend after weekend. 6 rounds a day. thats why a lot of people around here just run methanol. and keep it all in the same place as where the fuel they tune from comes from. same fuel, same temp, consistency=win.

its like top fuel around here seriously. even the mechanics have their own rituals, let alone drivers. i've seen a guy run 4.74's 1/8 for 8 passes in a row. wanna run super pro down here???

 

It's a generalization.
