What do you guys think? Every so often you hear someone say, "I got a strong motor". Or, someone with a slower car claims they got a "friday" car (the theory goes that by the end of the work week, the factory workers are tired and anxious to get out, thus their quality of work declines).
Is there really that much variability in the manufacturing process that some of our Preludes have more power than others?
Has anyone put several brand new Ludes on the dyno to compare?
This is especially notorious with Hondas... so I've heard.

I don't know but I would say the oil burning issue is a good indicator. Some have it, some don't. Somethin's fishy.

 

[BlueShadow]

i've heard that term too. out of 20 cars produced 5 are fast 5 are slow and 10 are about average. blah blah blah. there is no way to know for sure if that phrase is true. but "i've got a friday car" does make a good excuse for losing a race.. not that i'd ever have to use it, cause i never lose

obviously some have more power than others. this will apply to every car ever made. the question is, how much more or less. judging from the dynos i've seen (which can't always be trusted anyways based on the quality of the dyno and shop) it's about +/- 4hp on ludes, with low 160s being the midpoint... 158-166 for a stock 99+ 5th gen.

 

[MaverickD]

101% douht it~ come on~ it's a japanese car!

 

[dka]

in that one comparison where the SH went up against the gsr, itr, and gts..they dyno'd the SH at 167whp

 

[schwett]

right - i saw that - but discounted it because the number was printed in SCC. in that same test they got a 7.5 second 0-60 time, which is between one and .5 seconds slow. those guys are retarded.

of course it's possible, i've seen plenty of 165 whp stock dynos.

There is some truth to that statement. Every car & engine is a little different. Some parts are closer to the ideal specs and others aren't but still fall within the allowed manufacturing tolerances.

Honda does a better job of mitigating the extremes than most domestic manufacturers. My Prelude vs. my Suburban being a prime example...

 

[mugen22]

I think the inconsistencies are more a dyno issue than a motor issue. Hondas are built to the tightest of tolerances. Regarding the SCC article, did anyone read the Project GT-S article? Some how thier Celica had 10 more whp than did the HKS and TRD cars. Hmmmm.

Anyway, Honda builds phenominal motors and I don't think there is much difference from one to the next.

Rumor is that the SCC driver missed the 2nd
on that run. Bastard..
7.5 with a missed 2nd isn't bad

[kckckc]

Seriously.
I was told by an engineer friend in Japan
that honda engines made in Japan have
net tolerance variation level of about 2%
at Confidence level of 95%.

that's about +/- 3 whp.

but depends on what ever the underlying
distribution of that variation is.. i'd guess
+5 whp is possible, though quite improbable.

I brought lotta crap to this forum but if you've been here
long enough to remember, I am the one who brought all the
accurate news about 2001 Preludes
and about the demise of 2002s..
i.e. believe me it's 2%

kckckc-u da man, but why do you always disappear? I recall your post about sex being a higher priority than H/A. Does that still apply today?

 

[dka]

kckckc do you live in the bay area? If so, where?

 

[VeeTec]

Fact,

I don't care what Honda reps say. I have driven quite a few Preludes, and other Hondas, and I have found that there performance does vary noticably.

There is an awful lot that goes into the motor, not just the internals, but when everything comes together just right you get those that seem to run stronger than others.

My Prelude ran high 14's stock. Factory ringer? I have driven others that were noticably slower. I have also test driven countless other cars and came to the conclusion that most cars do have that middle of the road feel.....but some do run stronger..and even some slower.

Thanks everyone! I agree with veetec. I think there are definite differences in the output of different cars. I've come to think that I've got a strong Lude.
Case in point:
I stay dead even with a friends Type-R. We've raced a bunch of times, all from rolling starts at various speeds. Driving skill is equal.
I've also beat a VR6, and a heavily modded 5 spd 5G prelude (I was stock).
Regardless of HP or differences in cars, I still contend that it's the driver that is ultimately most important.

I'd believe 2% total engine variance "from the factory".
You're all missing the variable of how the engine is broken in. That can make a big difference. And I don't mean "break it in the way that you want to drive it", but break it in properly.

[schwett]

if you believe the gtech (and i do, to about +/- .1) my stock 2000 SH runs high 14s too. yet i see many posts of people with mods running 15.3 or so; either a) the mods are slowing them down, b) the driving conditions are less optimal, or c) the driving is less optimal. beyond that, there's a lot of more minor variables, like gas, oil, tires, wheel weight, air temperature, humidity, elevation, road surface, etc etc etc etc

anyone know how much variation in the ET 10hp would cause? how about 50lb of weight? 100? one stock lude could easily be 100lb heavier if it had a full tank and 200lb driver...
