i am not talking about displacement tho


the torque produced by typical push rod motors has nothing to do witht he way the valves are open'd

they just lend themselves to a low revving torquey motor, there is much more that has to be moved and has to be moved farther before the valve opens... the valves start to float way earlier than a OHC would... by float i mean they dont open or close all the way

civic coupe 1.7l
Bore X Stroke 2.95x3.72 <--- more stroke than a ls1 :P

So than it's the displacement. :P

for a production/street car there really isn't a replacement for displacement, I'll reluctantly admit that.

do I think that honda motors are better then ford or chevy motors? absolutely. not because of peak numbers though.

having pushrods in a motor is rediculous, we are beyond that now, I'm glad to see SOHC and the few and far between dohc motors in american cars. but I'm sick of people cramming ---- down my throat about how fantastic of a motor their god damn pushrod pushing, carbuerator sucking, old pile of american ---- is.

and for all these people bitching about numbers, compare them both at 1.0L (proportionately)

Mustang Gt 4.600 Liters displacement 302ft/lb peak torque
66ft/lb per Liter of displacement

LS1 5.665 Liters displacement 335ft/lb peak torque
60ft/lb per Liter of displacement

B16A 1.595 Liters displacement 111ft/lbs peak torque
70ft/lbs per Liter of displacement

B16B 1.595 Liters displacement 118ft/lbs peak torque
74ft/lbs per Liter of displacement

what were you saying about torque? ::)

japanese performance motors are for Road Racing there is a damn good reason why a CTR has 1.6L motor that puts out 185hp@8000rpm and 118ft/lb@7500rpm

but I'm with you, if I were gonna drag race, I'd have a large displacement motor, but to tell you the truth, for my application I've been thinking about going to a D15b.

Honda's technology is BETTER period.

Pushrod motors are absolutly not rediculous. Take, for example, the GM 3.8L V6. That basic motor has been around for 20 years and has over the years continued to become more and more durable. Its used in many of the old people cars which see 23-28mpg, not bad for a boat. The 3.8 is a strong, well built motor had can easily see 200K without a rebuild and provides ample power and torque (205hp 210tq) to get the car moving. The s/c application of the 3.8L is even more impressive. I think in stock form the GTP cranks out 240hp/280tq, and they can be modded like hell and can handle more boost (N/A uses high comp pistons and a diff. head) easily. I saw a gtp that put down 360hp and 495tq to the wheels while still having a reliable motor. Pretty impressive if you ask me. The Ford 3.8L V6 is crap on the other hand.

I detest mustangs......but that one I would rock in a graphite color with black deep dish rims and a polished lip.

I hated v8s,but now I have mad respect for them.If all goes well my next project will be boosting the 4.7 v8 in my Ram.On 6psi turbo calc. says it should make about 450hp and about the same torque...try that with a d16.
