My buddy has a "factory freak" 1999 Z28 with ONLY pacesetter longtubes, no tune or anything, and put down 370 rwhp! So it's definitely possible

That is entirely impossible on a stock LS1 engine, with an LS1 intake. Your buddy either had more than a stock engine or was on an extremely happy dyno.

Ok well I know what he put down believe it or not. Nothings impossible but even if it was because of the dyno who cares 370 is 370

you're right

an abitrary number assigned to the perameters of that particular machine.

maybe thats the same dyno that guys with bolt ons and a 224 cam only put down 425rwhp while the rest of the world seems to get 370-380rwhp.

funny huh?

my guess is your friends "370rwhp" car would run on par with a 320rwhp car at the track every night of the week.

again...funny huh?

Yes, a stock LS1 making 370 is impossible. My 12 years of experience with these engines says so. Dyno's aren't always the lord of truth. I can manipulate a dyno to say a 330hp car makes 400hp.

Yeah, it does seem like everyone has a low reading dyno. They should all look into getting those things calibrated, haha.

my car when it was only lid and catback put down 334hp and 333tq. thats corrected. it ran 13.0 and 110 consistantly. with a cutout and ls6 intake that sounds about right

Like I said this car stock with nothing more than a cutout trapped 109mph (and it had a K&N filter in the stock airbox), so with the lid + LS6 intake + tuning I can see the numbers. I was surprised, for sure, as I was only hoping for 325 after tuning. I'll be really interested to get it back to the track to see what it traps. I'm hoping for 111 in comparable air. The car isn't at all set up for drag strip ETs though so I'm only interested in the trap speed. I was having to give it every bit of what it had to get a 2.06 60' out of it the last time on the 19" street tires.

Nice numbers either way...
But what is up with these graphs having crazy out of standard scaling...If you look closely at the end part of the pull, there might be a little spike...With regular scaling it would be very noticable, but when the HP scale is so stretched its hard to see...Just a thought...

No idea on other places, but speaking for this dyno place it was during a dyno day, so we had some really low horsepower cars there (there were a handful of Mustangs ) and some really high horsepower cars, so they just set the scale to fit all the cars there.

Funny story, there was a '97 Cobra there with full bolt ons including headers and everything. It put down 268rwhp. On my last pull my MAF started to take a dump and my car was reading 4* of knock and pulling a whopping 13 degrees of timing, and my car still put down more power than the 4.6L Cobra.

i think this is around what these cars do if the plugs are fresh and they breathe well even on a stock tune.

Agreed. I didn't realize people still used the term factory freak, that was so 10yrs ago lol!
