What variables could cause a motor to 'run harder' than the common motor? Proper break in? Babying it for mad miles? better built at the factory? wat!

I have no explanation for people when they see my GSR w/ CAI and PS removed running next to cars that run 14.4's at the track from rolls (raced a RSX-S w/ CAI and testpipe last night - lost at the beginning of my 4th by a car -rsx top end ! ) - amongst others... Nother member on this board VTC_Civic dyno'd 161WHP on a gsr w/ cai and advanced timing..

Really a broad kinda stupid question but mebbe you can post similiar experiences.. I've heard the 95 and 99 gsr motors were the strongest from several sources any truth to that?

Just getting tired of people rolling their eyes n **** when I say I have a CAI and thats it.. need a better explanation

 

Good question, my friends m3 seems to run way stronger then my other friends m3. They say the faster one had a better break in. Not too sure though, since the one with the faster m3 is a better and crazier driver.

 

my LS motor was a freak. with 135k on it, and intake and exhaus tonly (ebay intake an WS mind you), i dynoed at 130whp and 124tq. with a gutted interior I ran 14.9@93. i would pull on GSR's and whatnot all the time. crazy. i think it had to do with my motor being old and had some carbon build up which actually raised compression a little.

 

Every engine is different, chalk it up to manufacturing tolerances and the law of averages.

Look at the history of the ZR1 as an example. The engines were made by Mercury I believe and they found variations of around 20HP (that's a guess, I don't remember the exact number but it was poretty high) on the early models. There was much confsuing and swearing as they magazines tested them and came up with much different performance numbers.

Cheers,

i dunno what does it , but we have experienced it a few times. my friend got an LS motor in his CRX. other than that bootleg exhaust and intake.
we dynoed it for sahits and giggles and did 138whp and 132tq. iwas floored

 

my car made just shy of 170 with bolt-ons w/ stock cams/cam gears/and compression.

Break in and a good ring seal play a role.

Also if the motor is maintained well, it wil run better. Like having items like the fuel filter, air filter, cap, rotor, spark plug wires and plugs, oils, etc... changes on regular intervals.

 

It's like my friends 91 LS. We all have decided that his motor is possesed because his car has regularly run with other tegs that have a lot more done to them and blasts others with the same mods. Go figure.

 

my ls has a freak in it to me....when stock i beat a few gsr's,haties with swaps,not to long ago i ran straight up with another ls...mines 96 his was a 99 not even close to 50,000 miles while mine just kissed 102,xxx after i left him by two and a half cars he goes pop the hood u have a swap in there but to his suprise all he saw was a itr strut bar...go figure..

 

yeah good topic,
im pretty sure that in 95 they made the fastest integras. i dont know why. bbut from the research i have done they are running the fastest 1/4 mile times. i have a 94 gsr with intake/exhaust and my buddy has a 95 ls with i/e and crank pully and he stays with me from a roll and pulls on me in 4th. its messed, im selling my car!

 

I really don't believe in freak motors. I believe in motors that have been properly maintained, and are "in tune" and I believe I good drivers.

Not freak motors.

 

another thing i just thought to ask you all. do you think gsr's are over rated? i mean i love my car but im having serious thoughts of buying an ls and going turbo with the excess money.

 

as it's been said.. break-in and maintenance serve in how powerful your motor will be.

but also.. mileage is a factor.

if you take a '99 LS with 50K miles.. and a '96 LS with 98K miles.. the '96 LS should be a stronger motor.

why? just for the guys that didn't know.. after the initial break-in (1000 miles).. your motor continues to break itself in more and more.. i don't know if i'm explaining this well..

but at exactly 100,000 miles (for most honda engines including the b18).. your motor is FULLY broken in. This is the mileage where it should be at it's peak performance, and peak power level (depending on how well you maintained it).

So.. when you got two of the same engines, it's more likely that the one with the higher mileage should be slightly more powerful.

Feel me?

 

some good responses..

wish it was explainable - only thing I can think of for my situation is my car was owned by an old man and I guarantee it never saw VTEC for it's first 60k miles..
Some people say that might actually make me slower.. but i dunno =P

My car felt dirt slow first week I owned it.... then all of a sudden w/o changing anything it pepped up.

I used to have a 1996 GS-R with roughly 65k miles on it, and I would constantly beat people that "don't get beat by GS-R's." All I had was an AEM CAI and Comptech Header. People would sometimes accuse me of having NOS. I don't understand it. I read once that it had to do with an error in the OBDII's used in early '96 GS-R's that gave them OBDI characteristics with the faster OBDII processor. Either way, the car was unexplainably quick and I miss it.

I've also read that there's a quality range that cars have to be in when manufactured (duh...), and anywhere in that range, the car will be at standard. The freaks are the ones that are not only in that range, but are turned out exactly as expected.

Other than those two ideas, I'm with everyone else in saying that it's all about normal maintainance and driver skill.

 

My friends 96 GSR ran faster than any other bolt-on GSR I've seen or heard about. It ran 14.7@96 or so at 3100 feet about sea level with intake and exhaust, stock exhaust manifold. It ran 14.5 or so near sea level. Only other thing he had done was no rear and passenger seat and no spare. He bought it from an old lady that probably didn't know what VTEC was.

 

my friends LS with ONLY exhaust beats my friends SI that has I/H/E my LS motor has been boosted for a long *** time and ragged on and it still running strong
... the person that had the motor before me had it boosted as well!

 

Back when a buddy of mine had a 96 Mustang GT, another friend of mine had a 96 GSR.

The Mustang had MAC headers, off-road H pipe, Borla catback, intake, MAF, 3.73's and pulleys and drag radials. The car was running low 14's and trapping around 98mph.

The GSR had a DC 4-1 header, leaving the cat, no catback, pulleys and cam gears. His best track time was 14.2 @ 97mph, but on the street from a roll, he would pull that Mustang like hell. Three cars or so just from the first three gears alone from a slow roll. Crazy to witness from the passenger seat of the stang, wheelspin was not an issue either.

 

60% driver 40% car... engine break in is essential... and running strait header and or cat makes you loose torque- and thats dyno proven- i ran strait header and lost 7flbs of torque but gained 6whp in top end lost sum in bottom end

 

Could even be variables in the machineing. Maybe the head was machined down too much (raising the compression), maybe a cam isn't in there "to spec" (thus advancing intake, retarding exhaust). You know, just inconsistencies that can add up.


Or maybe there just lying and since you can't see the internals, you take their word , Plus for all you know guys on the assembly line purposly do stuff just to give those lucky few a little extra something.

 

i dynoed my motor for fun at one of our recent meets, it's a 92 integra with jsut intake and exhaust and got 131/whp and around 120-125 tq(torque rating was in between that on the graph, didn't really show a true rating)

that's a 12 year old motor with 151,xxx miles on it

thats it

i have k&n filter, b20b head b20b intake manifold, stock exhaust and i hit 140hp
hopefully it'll go up a lil more when i put b18b cams in there rather than the b20b cams

30k on top end
230k on bottom end except a hone job and new rings

 

so does that mean that my 95 gsr with 66k miles isnt completely broken in yet?

That ls that beats the SI just fried his rings so you never know. hehe

ya ya, true but carbon glows and thus detonates so it isnt good at all. spray some carb cleaner down your plug holes
