Im Getting Conflicting Statements Here , My Hp Was At 173, Torque At 140 Shouldnt They Be Closer Together, Please Give Me Ur Thoughts!!! Thanks People!!!

 

I think that is about normal. Our cars don't produce a hole lot of torque like v8 and the like.

 

yeah exactly^^ its still good considerings its a 1.3. my caddy makes 300hp and 300tq

and a side note tq and hp cross at @5252rpms

 

the higher the revs go the bigger that gap will be, assuming the motor is making any power up high.

 

Thanks Guys

 

Power is the amount of force per unit of time. Presumably you have an n/a engine? You've probably made some mods that have a greater effect at higher revs than at lower revs.

 

I Have A Superchager On It

 

my tii does 182tq and 180hp @rw but I think if i went for more HP it woudl reverse the gap.

 

supercharged is only putting out 173? id think it would be higher

 

hp and torque are in complete relation to one another. i'd have to look up the equation, but horsepower, torque and rpm are all related. moving a torque curve affects horsepower directly. i believe its also common for rotaries to hit their max torque much later than piston engines. bringing up v8s is next to irrelevant. yes, they make lots of torque, but some turbo rotaries have "v8 sounding numbers." 20B were rated at 280hp and 296tq. true, its a 20B, but its still a rotary. likewise, certain mods done to a v8 may give it much more horsepower than torque.

horsepower = torque * rpm / 5252

HP = (TQ*2.0*PI*RPM)/33000.0
TQ = (33000.0*HP)/(2.0*PI*RPM)

rx7fromcal you got any pics of your setup??? I always like seeing supercharged engine bays

 

please, lets not get into this again.

I too wouldn't mind seeing the engine bay as well.

 

ttp://www.cardomain.com/id/rx7fromcali COPY AND PASTE, THERE ULL SEE PICS OF THE SC.

 

also, look at bike dynos. 600cc bikes make about half the amount of torque as they do hp. small litre, high revving engine. there's so many factors its crazy. wish i knew half of em.
did you ever get a good scan of your dyno? if so, i never saw one floating around. if you want to check your numbers (which would be a waste of time), i posted a couple of the equations. thing is, dynos dont read horsepower, they calculate it. then they can correct it to give "corrected" numbers (measuring a few variables such as barometric pressure and humidity and adjusting them).

 

oh **** thats you! I've seen your car before just usually your car is in your sig. ANyways very cool setup! What supercharger are you using?

 

great engine bay very clean and very well done two thumbs up!1

 

i believe its the Camden/Atkins FI kit. i'm sure it mentions it in his other (5 page) thread about it. hell, it may be in the title.
