what makes a car a "factory freak"?

Also, ECU tuning changes all the time. There are tons of different roms from Nissan, so some may be tuned more aggressively than others. I believe this is why we see some Zs/Gs respond so well to bolt-ons and a flash, and some to not gain as much.

I see what you are saying here, but wouldn't nissan put parameters on the stock rom set to a narrow range or particular set,thus not having the variation?

Even if you had every engine blue-printed/balanced by the same person using the same tools that had been properly/exactly calibrated (ie torque wrench) you might get the difference down . Too many parts that have been milled from so many different suppliers, too many variables!

Some car makers experiment with different parts, tolerances, and tunes.

My Dad worked in Ford Engineering and Service. He would often bring home test vehicles that were "modified" ....... and they would eventually be sold to dealers with no extra explaination.

One of my friends here in Houston has a factory freak. He has nothing but a single exhaust and intake (forget which but does it matter?) as far as performance, iirc.

He dynoed at 276-279 where other Z's (around 3-4 other friends) dynoed the same day, around same time, on same dyno (forgot type, but configed to output Mustang dyno #'s range), all DE's around same mods and they produced the usual 230's to 240's.

Your not crazy, lol. Ive heard the R35's can vary pretty unusually in numbers, but this is due to each engine being hand-assembled.

Yes sir. He's on the boards too I'll tell him to chime in here with the story. There were at least 4-5 z owners present during his pull also

ok, things are within reason as much as i thought they would be.. basically building one of those weak motors should very much bring it back to life.

I'll chime in with the video I made of that Dyno day.

I honestly dont believe in a factory freak car now a days where machines do most of assembling and QC, specs on engines.

In 7+ years on here the dyno differences Ive seen over and over are not huge, not enough to call anyones car a freak. The factory freaks are usually just called that when somebody that can drive runs a time that other non driving queers could only dream of. It is the non drivers way of saying "I can drive good but I ran 14.2 stock, he ran 13.7 his car must be a freak"

edit-btw that dyno video means nothing those cars ar emod'd so the differences have nothing to do with this thread. People dont realize wheels alone can rob 10whp.

FYI...He has Volk GTC's (not light) and only has an intake and exhaust. No TP's, no plenum spacer, no tune, no nothing else, pump gas...

Point of it being in this thread is the engine was obviously a gem from the factory. No intake, single and wheels alone can get a DE up to 273/277. So with that being said, how else can you explain it from a logical standpoint?

I have to chime in and agree. Pangoman's Z is freakishly quick and I can only imagine what a tune, TPs, spacer, etc would do for him...

Ive seen Z's dyno somewhat higher than norm like what you see above. I had 2 friends do 273whp back in the day with a few bolt ons where others were 250 tops. Later that weekend after the dyno day they didnt run or trap any higher at the track.

Thats why dynos are just tuning tools, nothing else IMO

What does his freakishly strong car run/trap? That will back it up, dynos can put out "off" results every once in a while, just like any machine.

My car always made a lot of power on a dynojet compared to other DE's , but I don't know that it was a "factory freak"

Were those pulls in 3rd gear? If you time each pull, they are 4 or 5 seconds long from idle to redline. Mine are always about 14s long.

True, assuming no missed gears and correct shift points trap can be very accurate, im just not sure what the extra +/- 23whp would equate to in mph gained at trap with all variables taken into consideration, including exact vehicle weight to plug in the net HP equation.

But dynos vs trap is an age old debate. The only argument w dyno's is between different dyno types, not multiple DE's done on the same dyno, same day, around same time, with similar to same mods. That leaves only the possibility of the dyno making a mistake...which yes, ive heard they can do, but how often and only trap's net HP equation to negate their results.

Not sure, i wasn't there, but im sure of the above guys who was will chime in.

Well 23whp over stock my car had a 5-6mph diff in trap NA. If he tells me he's trapped less than 106-108mph (which would be the norm for 260-270ish whp) Id say his car is not freakishly strong and/or he cant drive.

I like this idea of comparing his dyno to trap. There is an event coming down here on Jan 30th (show/drag). I know he has not gone to the strip that i know of, but i will do my best to convince him to do a couple of runs as i think he will be coming to the event anyways.

Not sure of how good of a driver he is, but he doesnt have to be any pro to get the proper trap mph for his whp range. Like i said, if he just doesnt miss a gear and nails the right shift points, we should see accurate results.
