conventionals to hybrids?

Has anyone proven to make more power with conventional stixs with big oil over stock oil with hybrids, just saying, I dare anyone. Prove me wrong please, everyone that holds an opinion on here, is this what you've read on here or is this something you have personally done and proved

shawn we know you make awesome power with hybrids.and spray...

thats the difference.
i am doing it myself. have you yourself tried the same size injector,hybrid and conventional, to see if hybrids made more power without spray?

the whole point of hybrids is for more fuel without the need for big oil. the offset is lower nozzle pressure. with the use of spray this will offset it.

with conventionals a large cc properly supplied with large oil, keeping a 7:1 injection ratio will definetly make more power, without spray.

i am not trying to picking a arguement with you either. i would just like to know if you personally have confirmed or denied any of this yourself..

Yes I have tried conventionals same size and they don't have the same fuel, I understand the math behind it, on paper it should make sence, I agree, but what works on paper and what works in the truck are two different things, so lets say you make 300cc conventionals, now stroke a hybrid the same with the bigger oil and now you have even more fuel, make the the letters as big as you want on this page, but the bottom line is, if you have a conventional and a hybrid stroke to the same, use the same oil on each, the hybrid will win every time.

Ps it's cute you try using BIG letter to get you point across LOL

Fuel only, I always make more power with hybrids keeping the same oil supply and stroke length in the injector

But Shawn i think you're missing what he is getting at. A 300 conventional and 300 hybrid don't have the same stroke. A 300 conventional will make more power with proper oil than a 300 hybrid. On paper at least lol since i dont know anything!. A 300 conventional, a 300 hybrid and a 300 stroke hybrid are all totally different you know that.

I know exactly what he's saying. And NO has ever proven that it works. But I was also getting the point across that if you compare apples to apples, injector stroke lentgh, the hybrid always has more fuel

How does the posi-trac in a Plymouth rear end work? IT JUST DOES.

I've done both...but I'm drunk and on vacation and that's all I'm going to type for today LOL.

Eric told me my 350 conventionals will make more power than his 340 hybrids on fuel only

Pizza pig · Mar 12, 2013

Precisely, those 340 hybrids have a stroke of 275 or so. Without the hybrid body they would be simply a 275cc injector.

g2shuck · Mar 13, 2013

Exactly and I was also told from multiple injector builders that conventionals will make way more torque due to the higher injection pressure

TooMuch03 · Mar 13, 2013

I guess it depends how you compare the injectors. If they have the same stroke length, then the hybrid should make more power, because of more quantity of fuel. If you have the same fuel capacity, the conventional should make more power due to higher injection pressure. At least that is what makes sense to me.

g2shuck · Mar 13, 2013

Right we are not comparing stroke though we are comparing injector size in cc such as my 350cc conventionals should make more power and torque than a 350cc hybrid on fuel only since I can hold icp

ding ding ding.

cc of fuel is the same. 350cc conven, or 350cc hybrid. shorter stroke,bigger bore, vise versa. its still adds up to the same cc for a given area.

the difference is with a hybrid you increase the diameter of the amplifier piston, instead of increasing stroke(which make a conven so oil hungary). now the amplifier piston size is no longer 7 times smaller than the intensifier piston.

injection ratio isn't 7:1 anymore. 4000 psi hpop x 7 = 28,000 psi of nozzle pressure

with a hybrid your ratio maybe closer to 5:1.

4000 psi of hpop x 5 = 20,000 psi of nozzle pressure.

now you can see what this does to atomization at lower icp. spray pattern isnt nearly as strong down low.

even at max icp with the lower atmo, the use of spray is needed to clean up the fuel thats being squirted into the cylinder at low pressure, versus being sprayed in at higher pressures.

before anyone says anything about injection pressure. gm, and ford bolth using the same cp4 pump that makes 30,000 psi of pressure. this is down from previous years where 26-28k was the norm.

Awesome job man. I could not have said that any better myself and I think that is the point some of us were trying to politely debate with Shawn on above.

honestly im not debating with anyone. im stating fact, of what is, and what isnt.

IMO I think oil flow threw the spool valve can be an issue. Ill have more flow data on big conventionals vs big hybrids real soon.

300cc injectors don't seem like much with a good turbo to clean them up. Go with 300+ and run a good ficm tune to pull PW out in the higher rpm range.
