Power number predictions

Hello all,
I dropped my '10 GT500 off at the shop this evening to be dyno tuned (Lund remote) with the addition of a trinity TVS with 2.4 pulley, VMP 67mm, JLT 123 mm, and complete exhaust off a '12 GT500. All guesses are welcome.
I did also upgrade to 56lb injectors, VMP fuel pump boosters, and TR6 plugs FYI.

680 if on 93 and a dynojet

My 10' with off-road x and CJ65, all other mods same as yours, made 656 with Lund remote tune on 93 octane.

Will be interesting to see where you come in.

I forgot to add it is on 93 ....., yeah I agree it will be interesting to see. I was frankly thinking more like 600-630. This is in the cinci, dayton ohio area so elevation isnt an issue here. I should have some numbers by friday.

Nice upgrades! What exhaust set up?

I put a complete '12 GT500 exhaust on it to keep the look and sound I liked, but with less restriction.

Well just heard from the shop, tune is done.......657 WHP and 608 ft lbs....so stetler17 you were almost exactly right on the money! Lol if there'd been a pool you would have won!

EXCELLENT RESULT !!!!!!!
That car will be a blast to drive, especially with the increased torque.
Congrats!

Thanks, picking it up tomorrow. Should be fun!

Please watch driving it in cold temps. I picked mine up before Thanksgiving after adding the TVS and tune and the temps were in the 30s and mine would spin the tires at 60mph
Mine has Nitto 555s and only 620 at the wheels !

Picked the car up friday, drove it home in pretty cold weather so light throttle all the way home. Talking to the guy at the shop they had to take out a bunch of timing because it's making 20.42 lbs of boost, the thinking is the air was really cold that day....so the hope is in warmer weather it'll have more reasonable boost, and they can add more timing.
They were impressed with the number it made with so little timing, so even with less boost in warmer weather maybe the same or slightly higher number? We'll see, I'm happy with how it sounds and drives so far though.

20 pounds is only a pound more than normal with stock manifolds and cats with a 2.4. Either way good results

Yours is the first one that I've seen be so close to what I got with similar mods. I can't find my dyno sheet, but my torque just broke 600, same as you again. Mine was in September/October of last year, so I also had good weather on my side here in Indiana.

Great numbers for a street car and RedZR's 620 is probably identical on any given day or dyno as well. I'm struggling with taking that next step and risking the drive ability and or ability to take off cross country when I want. Not sure my original goal of 700 at the wheels is worth pursuing at this point.

Congrats! I guarantee you are going to love it when the weather breaks in the spring.

So I've been driving the car a little trying to put some miles on the tune, which does seem to be maturing although the idle still dips pretty low at first when I come to a stop. I've noticed my exhaust tips are sooty, but don't know if thats from when it was on the dyno or driving it around now.
I'm thinking it may be a bit fat, so will clean the exhaust tips off and see how they look over the next few times I drive it.
