Default Cammed LS1 guesses?

All mods are in my sig. Will be going on the dyno for tuning in a few hours. Just curious what numbers you guys would guess it would put down as well as e/t and trap speed guesses? Thanks.

405 rwhp on a typical dynojet would be my guess

Yep, I'd say right around 400 whp depending on the weather and dyno.

Well it made 380... I was kinda satisfied but now you guys are making me disappointed lol. Air temp was 98 degrees hot as f--k. Tuner said it was the highest air temp he's ever tuned a car in. Do you guys think I'd gain anything significant on a nice cool day?

No one guessed any ETs or traps, do you guys think I could crack an 11.99 on street tires and stock 3.42 gears in good DA and temperature?

Don't feel bad them numbers are fine. This is with no under drive pulley too right? Number are just numbers. Do you have before numbers by chance. The gain is more important than the number. Also if you threw a cutout on it I bet you pick up some nice power

Full weight manual trans and street tires? Sorry but no, drag radials and a good clutch slip maybe, but most likely gonna need a bias ply tube type tire. Sticks launch much harder than autos.

Yeah, LS6 intake too. A FAST would probably put me at that 400whp mark. I dont have any before numbers because the last time it was on a dyno it made 280/362 with a bad fuel pump and no power past 4k rpm. So can't really compare to that.

Yes I'll try to get a picture up. Its a very smooth steady climb.

Mehh, cant afford to sacrifice my 10 bolt yet lol so as long as I can get a respectable trap speed at the finish line thats good enough for me for the time being.

At 98 degrees you're losing a good bit of power, what were your IAT's?

I remember the IAT being somewhere over 150 at one point. Not sure if thats high or not.

The heat was definitely killing power then, I'm sure when it's a bit cooler out you're very close to 400rwhp. Good numbers for high temps.

Depends on whether or not the graph is corrected or not.

Either way, dyno numbers mean very little aside from measuring gains or seeing the curves.

Yes, 150* IAT is very very high. You should see close to outside air temps either moving or with a dyno fan blowing into the car.
