dyno chart!!! - Honda Prelude Forum

preludegen4 · 10-27-2002, 01:53 AM

Hi, I'm new to this forum. After read postes one month, it helps me alot. I don't know how to paste the picture in this post hope this will help! If the link doesn't work, try to hit refresh buutton couples times. Here is my dyno chart:

This dyno chart show how much torque and whp I got in 3rd gear after I do the dyno tuned for my cam gears.
My car is 95 Prelude SI (auto) with 102000 miles on.
My mods: CAI intake, DC CC header, High flow cat, 2 1/4 custom pipe, exhaust, cam gears, pulleys, spark plug wires, coolant bypass.
What do yall guys think about this dyno? Is this bad or good after these mods because I spend alot moneys on it? Thanks.

Scalifludesi · 10-27-2002, 01:02 AM

166 whp...not bad at all considering those mods. Have you tested your 1/4 mile time yet?

preludegen4 · 10-27-2002, 01:45 AM

Not yet. The track is 2 hours form here. Could you estimate the 1/4 mile for me? Thanks

link doesnt work

166whp is great. That's pretty much VTEC territory. However, aren't they supposed to run the dyno from 4th gear? I thought it had the closest 1:1 gear ratios. Anyone have more input on that?

DOHCVTEC190 · 10-27-2002, 04:55 AM

Oh yeah, forgot to fix it for ya. Here ya go:

Are these SAE corrected numbers?

PreludeRacer023 · 10-27-2002, 08:17 AM

whats up with the large spike at the end, that dyno looks weird...mine was like a smooth curve the one time it was done...im confused

Satan_SRV · 10-27-2002, 08:51 AM

Oh yeah I just saw that....dude the dyno is very misleading....Your peak hp is something like 153 or so...it's that ridiculous spike at the end that gave that number....something is messed up there....

And why isn't the graph by rpms instead of speed?

166hp and 128 tq is ridiculous....a vtec is like 160hp 140tq, and the H23 should have at least close to 140tq to the wheels...I'd say you're at 150hp and 128tq...are these SAE?

Preyluder · 10-27-2002, 10:15 AM

Still, 153 to the wheels is pretty good. I'd guess that with good conditions, you could run right around a 15.8-16.0.

The guy who dyno for me. He put on D4. He press the gas slowly. He count 1st, 2nd. I think he meant 1st gear and 2nd gear when it change automaticly. At the 3rd gear he press the gas all the way in. Before it hit 4th gear he release the gas quickly. I think at 3rd gear around 6500rpm. He said he doesn't need 4th gear because the 3rd gear is strongest; that how tuned cam gear suspose to be. I don't know why my at the of my chart the spike cam up. Any body know why? Thanks

PreludeRacer023 · 10-29-2002, 09:06 AM

i think there was a glitch or something..it looks like its dynoing around 130 something which sounds about right for an Auto H23 with his mods...peace

Preyluder · 10-29-2002, 09:27 AM

No way, it's gotta be more than 130.

PreludeRacer023 · 10-29-2002, 09:30 AM

its an AUTO....most 5 speed h23s dyno at 130 -135 stock...an auto will dyno around 120 stock, maybe....he could be near 140 but i think hes in the 130s somewhere

preludegen4 · 10-29-2002, 02:48 PM

If my car is manual, can ya estimate 1/4 mile for me? Thanks.

Sorry to pull the BS flag on you John, but most 5 speed H23s will dyno low(edit) 140s stock. I expect mine with I/H/E to dyno in the mid to high 150s.

Thats if its a really strong motor. H23's will dyno around low 130's stock. Here is a link to a dyno of a h23 5spd with intake and he dynoed 136, then he put a header on and dynoed 142.

Preyluder · 10-29-2002, 03:54 PM

Wow, a 6hp increase just from adding a header? That's pretty impressive. I wonder how noticeable of a difference that would make.

Si4WS · 10-29-2002, 04:14 PM

But look at this, a much healthier: Max Power (corrected) = 155.5 hp, Max Torque (corrected) = 155.3 ft-lbs
with i/h/e

Taken directly from the page you put a link to:

"At the time, this car wasn't very healthy; it needed a valve adjustment and some new spark plugs, wires, and cap."

Pter's car with H/E, put down 149.2whp, and 151.7 ft-lbs torque.

Just dyno'd my 4th Gen Si...
