Hes not saying that a smaller motor is better, just that there are in fact ways of making the car faster without a bigger motor. of course a 2.0l will make more power than an identical 1.8l, but how big can you go without increasing the overall size of the motor? then what happens? you need a bigger chassis, which means more weight. If I was building a racecar (Racing, not car-bowling), I would rather have a small, lightweight, 2000lb car with a 300WHP 2.0L than a 3200lb car with a 350WHP v8. to hell with torque. its overratted. I know in a street car its a little different, because you use the lower RPMs a lot more, but I dont give a damn about that. When I need to go fast, I rev it. its not that hard to do. When I was street racing, I would get jumped on by V8s, but about the time Vtec kicked in, I started pulling, and then got past them before either of us shut down. "off the line" is for losers, its the finish line that matters. torque is the measurement of force, not off any work being done. Horsepower is a direct measurment of work being done. the amount of force developed (torque) is then muliplied into the RPMs to figure how much work is being done. why do you guys think that F1 cars run 18000 rpms? they know that they can get the horsepower to make up for not having the torque. a 3.0 that makes 700+ horsepower doesnt give a damn about "low-end" torque. and the phrase "low-end torque" just bugs the hell out of me too. you could directly replace the word torque with horsepower and it would make more sense. torque and horsepower have a direct relationship, so saying torque is more important than horsepower is ignorant too. They go hand in hand. a 1500 lb-ft engine with a 250 rpm redline isnt going to be very fast, but a 3.0 18000 rpm motor is very fast. so why dont the top fuel cars go to bigger motors than 500CI, and just spin them less than 9500 RPM? because they can make the insane amounts of power with "only" 500CI. yeah, thats a huge motor, but its not as big as it seems. at full throttle, they consume as much fuel as a fully loaded Boeing 747, and make 25% more energy. yeah, 8k+ hp from 500 CI.

 

We're not arguing that a bigger motor will make more power easier, we're arguing the superlative of "no replacement"

 

this topic is way over my head

lol ill stick to just knowing about my honda

 

Wow. Sacs.... whay arent you some high end engineer working out fo japan?

 

Simply going to say that 2 motors exactly the same in every way but one with more displacement the one with more displacement is going to have more power. That is where the addage comes from. Comparing motor to motor not motor to traction or weight yadda yadda....

*retires from thread*

Berz out.

Can't forget the boys over at GM's sport compact with their ecotec powered 8 second sunfire

In fairness though it runs on alchohol, but it uses the stock cylinder heads.

And for those with an ecotec engine, the racing team released a book detailing every single step required to get the car that fast, with instructions

 

All being the same as far as chassis, weight, and other things displacement owns I am sorry. Take this into consideration. A V10 from a Viper makes like 550hp and is a 8.3 liter engine. For Ferrari to make 700hp with a Enzo with a smaller displacement V12 they had to strap 2 turbo's to it. I am not saying a Viper is better than a Enzo so please dont break off into that. I am just saying all being on level playing ground, 2 engines ment to do the same thing, setup the same way, the bigger displacement engine will make more hp and more importantly more tq. Sacs you can not say the hell with tq, all hp is is a formula equated from tq.

 

bobby...sunfires are for girls...

but seriously, GM has a faster car now...its the team ecko car...still running an ecotec, but its a slowbalt body...i think that its in the low 7s, but i dont know the specs on the motor...

the moral of the story is that "theres no replacement for displacement" is typically a statement coming from someone who is biased towards whatever he or she drives, and is using that to try to talk down to someone else...ive beaten plenty of big block cars at the track who have over 100 cubic inches over my little motor...

on a side note, we have some pretty high performance cars here, and i expect to see our timeslips section reflect that this summer!! that includes evos!!

 

Should we even bring Diesel into the conversation? They like torque...they like it more then HP sometimes....and while gasers usually make equal levels of HP and torque....diesels blow the curve. Here is what torque does for you.
This is his daily driver...wow. Once again...lots of money to have big power.

 

i have raced against an 11 second CTD...it was embarrassing.
