Sbr Evo III 16g, 400 Whp???

Thanks for repeating what I said.

A 2.0 can flow the same amount at 195% volumetric efficiency. 195% VE is easy on our 2.0 DOHC.

That 195% VE is with the turbo right?

I didn't any N/A engine could get very high above 100% , maybe like 105% with perfectly tuned headers and intake track.

This is even late for halloween by bringing this thread back from the dead.

But yes...nothing, ever will have over 100% efficiency. You can have efficiency "better" than an N/A with a turbo but it doesn't make it 200% more efficient, may make 200% more power but efficiency must be <100. Or it just plain wrong and you screwed up a calculation.

So you're kinda right

My turbo puts more than 2 liters of air per intake stroke in my 2 liter engine when in boost. Even though the volume of space is the same, the number of particles is higher. ...

100% of 2 liters is 2 liters. more than 2 liters is more than 100% .Compressing the air can make 4 liters of air (at ambient) fit into 2 liters of space.

That's what happens when you skim the posts to quickly . Sorry man. Well, it's yet another way of explaining the same thing.

Haha no problem. I do it all the time..

Looking at your previous posts, You must be right...Lol; at least you explain it.

I was kindof looking at it from the standpoint of N/A efficiency of an engine and turbo efficiency of an engine seperately so they couldn't be over 100. But If you look at an N/A vs. a Turbo then it would be what your saying.

OOOHH! yes. I see. you're separating the all motor VE from the total VE of the system. In that case, i agree with you. Unless you can take the head off and put it back on in microseconds, it is near imposible for a naturally asperated engine to even approach 100% VE. I THINK nascar has done it and maybe on the level of some 180+ mph drag cars. But that's why they say that there is a replacement for displacement. God Save Forced Induction!

A-men

off the topic of displacement......wouldnt sbr have made a good amount of extra power using dsmlink? i dont have dsmlink but from what i hear it is defintely worth it.

Yea DSMLink can give your setup all the room it needs. You can advance the timing at particular rpm points and lean out at particular airflow points. Basicly letting you run to the ragged edge. Maybe they could net 30-40 more ponies. I don't know. But I'd think that the main reason why SBR makes that kind of power is cams, intake, and exhaust.

Sooooo, at viper engine may actually suck more air than an evo3 16g can give it at 20 psi. It may draw the boost down to 0psi. But even then, 0 psi is better than 18 inches in vacuum.

So at WOT the viper will still have 18inches of vacuum? I thought it goes to 0 at WOT?

I'm no genius,

Probably, yes more power could have been made, we just had that car sitting with a VPC and an AFC1 chilling in the corner ready for some product testing! We didn't really plan to make 400 horsepower that night, but after a few pulls everybody got excited and the tweaking began! I give DSMLink two big

 

[never2muchBoost]

wow, it would be awesome to see u guys throw down 430-440 with a 16g and basic bolt ons. probably 4 thousand dollars worth of dyno runs for the average joe though, haha

Insane... I heart my DSMLink! 400 whp. I plan on camming and adding a SMIM. I have an 18G. I hope I can get those numbers. Even if it's just on paper and i have to dial it down for some reason. Weren't you guys running race gas?

i belive it says in his first post that they were, but i dont know why if it was only at 22psi with 650 injectors, i would have thought 93 pump would have been suffient.

 

[SlowboyCSE]

26/27/28 psi, what ever the stock gate would spike and tapper off to. Most of the time 26ish.

Sunoco 120 Octane. We have since switched to VP C-16 and VP Import 120, they are better fuels by far for forced induction motors.

I'm an idiot. I don't know how big the intercooler is or how aggressive the timing curve came to. I think it would have been possible too. That horsepower level is my final goal for my FWD. I have 650s and WI and a Walbro 255HP and an 18g. I've always wanted to be able to still be able to pull into a gas station and fill her up and still drive away with 400whp . I don't know if it will happen.
