Regardless of the hp:cui ratio pent/hemi technology used in production cars is wasted on some turd mopar trucks and SUVs. And no one here has even said exactly what gains a hemi combustion chamber will give you in an apples to apples comparison. I'm sure you could get 1500hp out of a lawnmower engine too but you won't see a John Deere under my hood.

 

guess the hemispherical heads suck eh? see dodge getting banned from NASCAR in thee 60's......

 

Supras rule.

 

hey jeff, when did you do the engine/tranny swap on your SLR?

 

hahah I can barely change the plugs on the vette without f'kin something up

 

Hmmm i can see your side.
I never said a lawnmower engine made 1600hp. The mopar trucks and SUVs are not the only ones using the design, just because it does not say hemi doesnt mean they dont use the technology. Top fuel uses this and i am pretty sure they arent turds.

Its kind of hard to compare hp gains because i dont know of a motor that will except both types of head designs. But flow test and simple physics show that the combustion is evenly destributed across the combustion chamber more so with hemispherical design than wedge. But both can get the job done in a sense.

Like i said, dont get me wrong, GM is doing a good job with there engines. Does not mean its the best though.

GM All other companies also Toyota

 

duuuuuude, I think its time you get over it bro, move on! leave the past in the past

 

NO!

 

how bout 410?


dick.

 

Well, I dont buy a car because it has some uber engineered motor. I could care less about that. If i wanted HP/Liter, i would have gotten a Bike. HP/Liter doesnt win races. Besides, you can have all of the peak hp in the world, without area under the curve it means nothing.

And people are getting 500whp out of a cam only LSx cars. If you do that math, thats ~570 crank hp, which is 100hp/l. Now that is 100hp/liter with only 2 valves, pushrods, and a radically larger powerband. What is more impressive to you, 500whp or 200whp?
