explain this then....

Lotus elise:
power: 189 bhp @ 7600 rpm (flywheel)
weight: 1975 lbs
weight/power: 10.5
0 - 1/4 mile 13.2 seconds
the escalade at 5 lbs of boost:
Power: 455 hp
Weight: 6055 lbs
weight/power: 13.3 (worst than the elise)
0 - 1/4 mile:14.2 seconds
escalade at 13 psi:
Power: 615 (roughly add 20 HP per psi)
weight: 6055
weight/power= [color=red]9.85[color] better than the elise.
0 - 1/4 mile: 12.88 seconds. Keep in mind that the escalade was set up to drag that day. Other wise IMO it would have been closer to 13.1.
info on the escalade can be found here:

Yes power to weigh ratio is not everything but it what makes the most difference in street driven cars.

on a side note every 100lbs is 10th of a sec... so if you have the same cars and take 1000lbs out of one of them it will be a sec faster in the 1/4 mile

It's obvious...he's wrong and can't admit it. The only way he can start to validate his point is to compare extremes like you said. First it's bikes to cars...then it's large vehicles that are almost like flat walls when it comes to their aerodynamics.
Heaven forbid he compare a car with a car and deny that power to weight doesn't mean anything...why does he not use these examples? Because then he'd debunk his own argument...and we can't have that now can we?
In any situation where you compare apples to apples...power/weight will be the most significant factor. The End.
Oh and just so you understand bikes to cars would be like comparing apples to trees....a bus vs. a car is apples to oranges...and 2 cars would be apples to apples.

man none of them are any more importaint then the other... tracktion seems to be a biggie also in the street... if cars dont hook up they dont move very fast power to weight didin t help very much... now if you have a car set up to hook and you gut it you have a faster car... power to weight plays as bigg a roll as traction dont you think?
and in the street the things i look for to determan the out come of a race is tires...
how many ppl that have commented in this thread saying i am dumb have anything to do with racing besides in the street???

no i didint bring that up i belave matty did i just used it

there is no way i am wrong when i said there is alot more factors to winning them just power to weight
and using that extreme example "bikes to cars" how is that any diff that puts the power to weight to about the best example of what you say is the key factor.... i also used crx to mustang what is so extream about that? or we can jsut say FWD vs RWD seein as most FWD's are much lighter then the RWD yet RWD cars still put down faster times..

nobody here is saying that power to weight is the only thing. But it is HUGE and it makes the most difference.

every car that me or my friends own from domestic to imports all run very close to what the physics dictate. this is real world with many many yrs of drag racing and having fun on the street experience.

You ASSume too much. Please quote me where I said power to weight don't matter. I posted the varibles after someone brought up the drag race comparison between car and bike. The link clearly says power to weight has the greatest affect on MPH ( what you are comparing roll racing) You were too busy waving around your big E-***** to see I was on your side. Excuse me for not writing a ******* essay on each variables effect and what matters most.

well, back to the race...Nice! nothin some diet and exercise cant cure! get a stand alone and more boost!!!!!!!!!!
the only thing...they could have picked a slightly faster chaser.
oh btw, those 99 twins must be the ****...stock ports and boost levels on stock seq. sys.(10-8-10 boost pattern he was wondering about at the beggining of the thread).
if it wasnt for the mani...or the limits lol

..... i was jsut pointing out that with out traction weight to power dosent mean much... and that its not ALL ABOUT THE WEIGHT TO POWERsorry for getting this post way off topic
