yeah i think im going to have to go with dan03mach on this one. its not the overall size of the engine you would use to measure efficency its the cubes that matter. heck im not even so sure that a 4.6 is really that much bigger than an ls1 youve got to remember mustangs are smaller cars than f-bodies

 

I disagree...I venture to say not only is it bigger its also quite a bit heavier. And I dont agree with the ricer argument of hp/liter or "motion in the ocean".... Size matters.

 

What is heavier?? My motor is all Aluminum.. Its pretty light.. If you look at the motor the size of it is larger by means of taking up more space.. But the block it self is alot smaller.. The heads and OHC's make it look so much larger then it really is..

 

Heavier means it weighs more. Bigger means it takes up more space requiring a larger engine bay.

 

Geez I can imagine when I finally post a thread about beating a stock LS1 anything, there's going to be like a 10 page thread of arguing accompanied after it...

 

Yep. It seems that way huh.

 

what does the GT dyno NA

 

LS1's never loose.

 

maybe a different track.

 

true there is no replacement for displacement, i was just commenting that if you wanted to measure efficiency i would think you would measure hp/liter as far as power production goes. by no means am i trying to say a 4.6 is superior to an ls1 because theyre not ive raced a few modded 4.6s with my stock ls1 and they just cant hang with the tourque a bigger motor produces.

 

The 4.6 is not a motor to be racing N/A heads up that's for sure. In the world of N/A you NEED cubes plain and simple. But IMO there is a coolness factor to go fast on little motors. That is why I choose to stay N/A for now until I hit my goal. Now FI is where the 4.6 shines, mainly the 4v's.

Good kill Adam. -Mark

 

yeah definitley look at the 03/04 cobra $2000 and you have 500 reliable hp

 

Does it really matter???

 

Apparently to him it does . I did 258 on motor.

 

adam02gt, If you know your car can beat a stock c5 why dont you try a Z06??? or is it just to much? and another question when are you going to realize that this is a fourm for gm products primairly ls based motors hint hint "ls1tech" go find a mustang fourm.

 

Same goes for you and that work truck of yours.

 

I've already raced a Z-oh I had a fender on him till 4th gear then he walked me. And Guess what you can kiss my *** on the forum thing.

 

You are a tool 06sierra2500...

 

See sig... 36k on the clock and going strong... knock on wood...

 

Im going to race a new z06. J/K, but my friends dad is finally getting one. If Im lucky enough, I'll atleast get to drive it once
