What kind of difference you you expect from a car if it had the Torque to match the Horse Power (square motor)? For example take a car with 606hp but only 384ft/lbs vs. a car with 606hp and 606 ft/lbs given the suspension and everything else is the same. What kind of difference would you expect in ET and traps?

 

i dunno, but it would pretty much just come down to one of the motors revving very high and one revving to like 5850rpms i think it is...

 

Im assuming you already know that HP is a function of tq. (tq X rpm/5250 = HP)

You have to remember that a honda making 606/384 is doing it w/ a 9-10k redline. It has a big big big gearing advantage over a car that revs to 6k and makes equal tq to the hp...

It is still about area under the curve but you can't just look at the #'s alone.. think about it, a car revving to 10k is never going to make equal tq and hp, and if it could, you would never touch the rev range where its making the big tq #. You have to look at the whole picture. Not just HP and TQ but gearing too.

 

Our car is making 400 hp and 360 trq to the wheels via LS/VTEC turbo. The car runs 10.60's at 134. Do you think Alexei's car would have lower et's if he had a GSR motor making 400 hp and 300 trq? Anyone else with similar et's, Hp and weight?

it matters a great deal in a fwd vs rwd car ... that high tq/high hp motor will rev to maybe 6Krpm ??? traction will be a HUGE issue in a FWD chassis ...

I drove a friends fully worked h22a turbo EK civic in the street with 25" slicks (street racing days years ago), the tq on that motor was close to 450 @ wheels (hp a bit under 700 @ wheels), 4th gear was the only gear that had any decent traction, 1-3 spun and barely grabbed until it got to high rpms (around 7-9krpm) ...

it would do a big burnout all the way down the track!

That's really all you need to know.

 

hondas dont need torque because of the gearing. they have short *** gears compared to other cars. torque is multiplied by gears. ie if you have 100ft lbs of tq anda 2:1 gear then at the output of the gear you will have 200ft lbs. the catch is you need more rpms to have a good top speed. thats why a honda with 210hp and 140tq will run 13.0. its all about gearing.

another example. we dynod a twin turbo porsche that made 510hp and 470tq. the dyna pack measures actuall torque at the hub, the porsche was around 2100ft lbs in 3rd gear. the civic made 510hp and 375 tq, but we couldnt dyno it in 3rd b/c the tq at the hub maxed out the dyno, we had to goto 4th gear and made the same tq in 4th gear (2100ft lbs) that the porsche did in 3rd. so even though the porsche had more tq at the engine the civic would be a faster car b/c of the gearing. put the porsche in 3rd and the civic in 4th and the cars would accelerate about the same, but in a real race the civic would roll the porsche

 

remember a couple years bask when the fad in the honda camp was to turbo a h22 and put it in their civics. the fad didn't last that long because the torque was too much. they could spin their tires just about anywhere on the track. most everyone went right back to the b18s. yes you do need torque to get out of the hole but too much at the front wheel and you ain't going nowhere
