Hey guys, I've been dormant from the s2k forumn for a while. Just thought I would share with you my dyno numbers from yesturday. I have a 04 ap2 with 45k on the odo.

Mods:
ARC Intake

[IMG][/IMG]

I was very happy to see my motor pulled 207.1 hp and 147.1 tq. I was content with these numbers. I'm anxious to compare this to how she will do once i throw on the j's header, hks exhaust, and get a nice tune with the AEM EMS.

And just to be on the dick side, an ap1 did a dyno pull right before me and throw 185.7 up with an AEM cold air and megan exhaust.

Damn. That doesn't sound right at all. over 20 hp difference? Crazy. Ive raced Ap2's and haven't had a problem pulling on them a little with my ap1. Im slightly modded, but not enough to have a 20 hp advantage.

All that aside, VERY nice numbers man

 

Those numbers seem a little low to me, especially with an intake, I guess ARC intakes really do hinder more than help, my motor put down 213.1 bone stock with the airbox shut ::thumbs up::

 

all dyno's are different son<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 06S2200 &raquo;</TD></TR><TR><TD CLASS="quote">Those numbers seem a little low to me, especially with an intake, I guess ARC intakes really do hinder more than help, my motor put down 213.1 bone stock with the airbox shut ::thumbs up::</TD></TR></TABLE>

Just 207? My AP1 made 213.8 with just a K&N and HKS Exhaust. Oh well, I'm sure the car tried it's best

 

207 seemed good to me. I figured you'd lose at least 40 horsepower by the time it got to the wheels. Hm..maybe i underestimated our cars

How do you figure the intake hindered performance? No dyno was done with the stock airbox, therefor can really any conclusions be made? Your assumption may be right, but it can no way be made from my dyno.

Like I said, an AP1 went right before me and only threw 186.7 up. This is something worth noting because it actually was the same dyno, same day, same temps. Your dyno doesn't do anything for comparisons since all those factors are different creating too many variables for a liable coparison.

I thought the same honestly. I was just hoping to see 200. That extra 7 was just an added bonus to me. Although our cars are rated 240 and with the new SAE ratings I guess our cars would be rated 245 250 from factory years ago. So kinda keeping that in mind, 207 would just be about right from 245 250.

 

those numbers seem good to me on a dynojet i got 225/155 with an ap2 intake/exhaust/testpipe/vafc2. Goodluck!

Ownage

 

how was there a 7hp difference ? heat soak on the 2nd run ? great #'s.

What do you think you would pull out of it if you would upgrade from a vafc2 to a full engine management like the AEM EMS?

It was just an observation. ... but on a serious note, it was just for comparison purposes. Not trying to say anything on the ap1's, still love.

To be honest with you, I kind of thought that 7 hp was a big difference too originally, but then I was like you, I just thought it was some crazy heat soak. 207 was made when they let the motor run for about 15 mins so I would think that there would be ample heat built up already. I don't know, your guess is as good as mine on this.

 

HP seems a little low.

When I went to the dyno day 6 months ago, most AP2's were pulling in the 216 range stock or one or two with an intake.

Mine made 216 in 3rd, 218 in 4th, and again in 4th made 221../147.7 w/o air cover.

Honestly man, every dyno reads different

 

well when i got my car tuned it helped make the whole powerband more useable, so in most instances having those awesome numbers mean nothing if your power band has dips and what not. I havn't done that much research on the ems but i always though it wouldnt be as much needed unless you had major bolt ons or forced induction. But im pretty sure the tuner will be able to finer tweak certain things. goodluck!

 

You need a bigger scan of the dyno, Eric.

As for the people claiming the numbers look low, comparing different dyno's is like comparing apples to oranges.

Every DynoJet reads differently. Period.

The only true way to compare numbers is a back-to-back comparison on the same day, same ambient conditions, etc... The AP1 reflected what I personally have seen to be true: F20C's make less power than F22C's overall.

Automotive manufacturers have been fudging ratings since the Model T rolled off the assembly line. Just because the F22C's are rated at exactly the same power as the smaller F20C's doesn't mean it is.

An engine making more torque at the same RPM as another engine will make more power. It's simple math.

Eric's S2000 is making around 135 ft.-lbs. at 8000 RPM.

HP = TQ x RPM / 5252

135 x 8000 / 5252 = 205hp

The F20C's graph had a very similar torque curve, yet was about 13 ft.-lbs. lower at the same RPM.

There is nothing wrong with either car. The bigger engine simply makes more power.

Don't be butthurt, AP1 owners. At least your car revs to 9,000 RPM, right?

Can you click on it so it comes up bigger?? Thats what happens with my comp for some reason.

Good write up though. I think you'll have a lot of strong comebacks though.

 

Yeah even if the numbers do look low who knows what dyno it's on and what it reads normally.

 

nice #s, I know the ARC intake has a bad habit of heat soaking, that's probably why your subsequent run was lower.

 

Was it an early or late ap1 that tested? 00-01 or 02-03? I've seen the newer put down slightly higher #s consitently.

My gf's 02 made 200/135 bone stock w/ a kn drop in. made 199/132 w/ the airbox lid off. oem engineering ftw

145 tq..

145 x 8000 / 5252 = 220hp

on the other hand, not all engines comes out from the assembly line has identical hp... some are actually a ringer... and i would bet that some AP1 can bet some AP2 with same day same dyno...

It wasn't making 145 @ 8000 RPM, Jesco.

Leave the calculations to those with more than half a brain.
