cai/h/e on manual d17 nets probably 10-12 whp. not a ton of power, but then again, it's still a sohc with a very mild cam that isn't pushing a lot of air
heh. that's wishful thinking. you'd be lucky to get 10whp off i/h/e on the D17.
and even if it does, this is still considered close to stock. 10whp could BARELY maybe .1 seconds off your 1/4 mile.

lol dont need dyno graph, do the math....115 at cranck, 15-20% is lost by the time it gets to the wheels...
another incorrect assumption. each car will have a different amount of loss to the wheels. even then, 20% (which is a lot for a FWD car) is still 92whp as pointed out. and it's likely closer to 100whp.
regardless, i/h/e on a D17 is near stock. 10whp could be gained if you're lucky, and even then, you'll barely pull on a stock D17.
my friend dynoed his cai and he got 2hp more...yeaaaahh.
header will make 10-12hp with the exhaust you will make yor flow
beter you will realy make 15hp max if ya dont believe that try it and
you will find out.ask other people on the forum they will tell you the same
thing.

I don't know about that. I've seen a couple i/h/e d17's putting out 115 whp ... if you want, I can try to find them.
iirc, I do remember seeing a dyno for a d17 at 120 whp and 125 whp as well ...
not on dynapaks either.
unfortunately, if you dont have a baseline dyno, it doesn't mean much. for all we know it's a factory freak, or that particular dyno reads higher. (all dynos will read somewhat differently and will have a 3-5% variance)
even at 15whp, again, you'll get about .1 seconds off your 1/4 mile. i consider that near stock or pretty close to stock.
^ I think 15 whp would shave off a bit more than .1 seconds, yes?
if we were to put a turbo kit that added 80 whp to the stock 100 whp, we'd get 180 whp... but we would also shave off more than .8 seconds ...
I suppose I'll try to find those dynos. off the top of my head, kornsined (sp?) dyno'ed at 115 whp i/h/e .. and carbonfly dyno'ed at 114 whp (iirc) with i/h/e.
if you only gain 5 whp with i/h/e, then the 127 hp rating only has 13% drivetrain loss... then again, gearbox's d17a2 baseline was 90 whp ... he does have an auto, but again assuming the typical baseline is 110 whp, I don't think that having an auto tranny drains 20 whp, hm?

unfortunately that logic does not apply to n/a mods. mods with FI such as turbo charger drastically increase area under the curve, not just peak horsepower.
n/a form, sorry but 15whp isn't gonna get you much past .1 off your 1/4 mile time. n/a mods like that give you nowhere near the "area under the curve" gains that FI does. apples and oranges.

unfortunately, without a baseline dyno, the numbers are meaningless. we need to know what they were making BEFORE they put their mods on their cars. quoting a completely different car on a completely different dyno doens't help much. the error variance in a dyno alone (3-5%) dictates that.
15 whp will shave off more than .8 seconds on a d17 because it only has around 90 whp stock. If you are talking about a LS1 Z28 camaro with 290 whp stock and then adding another 15 whp the camaro would only shave off about .3 seconds. Its all in the percentages. A 15 whp gain on a motor with only 90 whp stock is a good gain.
what? that made no sense...... your car does NOT increase it's acceleration due to the percentage of power you make.
15whp will knock off no more than about .1 seconds on just about ANY car, civic OR LS1. the only measureable variance here will be gearing and weight. and even then overall it has very little effect.
you are so wrong s2000man...making 15hp on a civic with baseline 95ish hp is a HUGE cain compared to a chevy ls1 making 350 or so hp. Although the power gain is the same, the differnce is greater in the civic due to the heigher percentage of power gained. it will show you that on the quarter mile. How else would 250hp civics run as fast as a SRT-10 making 500hp? Nearly double...
think about that one
that has nothing to do with it why do i beat my friend boosted 230hp/310nm is200 with my 140-145hp???? because my car is alot lighter.shorter gears.....
here if ya dont believe make sure you got xvid codec http://users.pandora.be/r-speed/lex.vs.vic.avi

thats hilarious...
