ls1 dyno
I have a 98SS bone stock I dynoed 300rwhp and 316rwtq
With the eddition of a wisper lid the same day still strapped to the dyno
It Made 307rwhp and 322rwtq
Car had 26000 miles on it and it was done At NE dyno tuning 1/14/04
On a dyno jet. Did you dyno on a mustang dyno?
The car may just need a little attention.

I find this kind of funny because 2000SLPZ28 made 269 rwhp and 296 ft/lbs of torque and
6spd99formula made 276 hp and 307 ft/lbs of torque with their stock ls1 cars
I've got a 94 lt1 car with slp intake and hooker catback and that is it and i put down 270.9 hp and 314.4 ft/lbs of torque (take a look at link at bottom of thread) but i still get flamed when i say that i have run with and beaten some ls1 stock ls1 powered cars
by no means am i accusing you guys of this i am just stating that there are some ls1 cars that dont put down that much more stock than some lt1 powered cars but a lot of people still think its impossible to beat an ls1 car with a lt1 powered car stock vs pretty much stock.
sorry guys for the little rant

i just got incredibly lucky when i bought this car it's somewhat of a factory freak and doesn't even have the notorious intake manifold oil leak (knocks on wood...) or any oil leaks for that matter the dyno was done with 70,000 miles on the clock

While i was at the track that day there were a lot of stock or close to stock ls1 cars running and i got to talking to some of these guys and stock or close to stock ls1 cars were only running 101-102 as well
this spring when the track opens back up im hoping to do a bit better and get some updated times but for the conditions of that day my car was running comparable with all the stock ls1 cars
I have a question for some of the guys with autos dynoing on the low side, did the shop lock the converter during the pull? If the converter were left unlocked that's where your extra rwhp may have went. You're dynoing 20-30 rwhp under the "norm" (290-300 rwhp) and that's the range for an unlocked verter to lose.
Number two, it's nothing for KR to put you well under the 300 rwhp mark; and a lot of LS1s have unexplained knock retard (probably tuning related) bone stock. I know my old `99 was running consistant 13.2s @ 101 mph with ~3° retard, I finally got rid of the retard and droped to 12.8s @ 106 mph. It makes a BIG difference.

so your stock '99 (i'm assuming f-body since nothing was mentioned otherwise) with tuning ran a 12.8?

i would get it dynoed somewhere else to see.
I dynoed with a lid at 296rwhp/306rwtq at cartek(everyone that day was down about 15 on hp)
Dynoed at Exotic motorsports with a cutout and went to the numbers in my sig, and their dyno was more or less more accurate than the cartek dyno for that day.
But the true dyno is the track, and i trap 108, so the latter dyno was right on.
