more torque than HP???
 

is it possible to make more torque than hp on a honda motor? with my car going to be done soon, im starting to help a buddy with his turbo project, a DA integra ls with usdm itr pistons ( 10.3:1 c/r) the set up will basiclly be a fmic,super 60 t3 .48/.60, 450's,pr4 with turbo edit, blah blah, about 8-9 psi........but i have seen the ls motors make close to the same hp and tq numbers before...could a high compression ls with boost possibly make more tq than hp?

stroker kit.

Re: more torque than HP???
 

i think i saw some A-series motors putting out sick torque figures, but who cares. just build it to make a ton of both

Re: more torque than HP???
 

That's right, my A series is torquey as ----

Re: more torque than HP???
 

when i did a base run on my setup i put down 167hp and 172tq. that was on the afc hack and very untuned! i now have TE and other better parts so i know i'm making more power. this is on a d16a6

Re: more torque than HP???
 

Look at some dyno sheets of bigger motors with smaller ball bearing turbos. HP is just how much torque it can apply in a given time (same torque but double rpm's = double hp [bad est.]). If the motor can't rev high or the turbo can't feed the motor up above, a small fast spooling turbo will crank to xxx lb/ft torque and drop off. I think on turbod16.com their dyno sheet collection has a few t3's that manage this.

i hope to accamplish more tq than pwr with my D16A6/K03S setup.
honda with tq...who woulda thought??

Re: more torque than HP???
 

it's a really dumb idea. Since HP and TQ are mathematically related, anything over 5250rpm will have more HP and anything under will have more TQ. Making power is all about flowing air, and small displacement multivalve engines flow at high RPM, so why would you want to avoid that?

Besides, HP > TQ because gearing can make TQ where there was none, as long as there was HP, but cant go the other way.

Re: more torque than HP???
 

if you use long intake manifold runners you should have a sick torque curve

Re: more torque than HP???
 

maybe i'm confused but ,i thought you cant have HP w/out torque, being as HP is derived from Torque.

Re: more torque than HP???
 

you are right, HP is a product of torque, rpm, and the magic number 5252.

Re: more torque than HP???
 

yes but you can still have more tq then horsepower, horsepower is a function of torque. Look at diesel ----, many times youll see a diesel with 120hp and 275 lb ft... If you play with your cam timing a little bit, and stick to a stock ls head and intake manifold you could probably get hp to = tq... i think random strikes teg was like 240hp and 215lb ft or somthing like that i forget but that was on his stock LS motor

Re: more torque than HP???
 

i was on a dyno while i had a leak in the intercooler,i made 164Nm torque and 90Hp,curve showed that after 3000rpm the whole thing collapsed coz of that leak...thus i ended up on the stock 90hp.weird ---- that was

Re: more torque than HP???
 

the only thing i cant see is, why would you want to limit your hp to make more torque, when you could try and just make as much of both of them

you will not have one without the other, just make as much of both and not worry.. will i have more tq than hp.

Re: more torque than HP???
 

My dyno sheet says 171hp and 176 flbs. I made more torque than hp.

Re: more torque than HP???
 

uh, mine was 225hp 240ft-lbs.

Re: more torque than HP???
 

get a starion. you can make 250 hp and 350 lbs of torque, mainly cus they have a big ass engine, and a small ass turbo.

Re: more torque than HP???
 

why not get a BIG ass turbo for that BIG ass engine so you'll get BIG ass HP and TQ. O0

Re: more torque than HP???
 

LS engines produce higher torque than most other B series engines because of the longer rod/stroke ratio. But, the longer rod/stroke ratio also means it won't be able to rev as high and keep building power (stock). The head/IM combo on LS engines are another power limiting factor. Build that bottom end, port and polish/build the head, and you've got one hell of an LS. >:D


Sory... Had to try the new smiley

Re: more torque than HP???
 

These new smileys are badass!

Re: more torque than HP???
 

the 89 CRX HF was 1 of the first honda engines to come stock with more HP than torque
;D but thats just what i heard on a crx forum

Re: more torque than HP???
 

Horsepower=(Torque*RPM)/5252
So you will always have more torque than hp under 5252 rpm. Above that rpm, hp will always be greater than torque. Whether max hp or max torque is higher will just depend on the type of engine.

Re: more torque than HP???
 

I had 130ftlbs of trq and 110hp before my car was warmed up, by the time it warmed up my dyno time was over. Base run on a f22a1 with cam, intake, exhaust, aem cam gear.

Re: more torque than HP???
 

Longer stroke and bigger bore is the only thing I can think of to increase the TQ out of a honda motor.

I dont follow honda engines that much but I was wondering if 10.6:1 is to much compression for a 9psi setup... I mean that boost plus the high compression ratio looks like high temperatures pre ingition. Anyone car to ilaborate on how its " safe" to be a DD?
