    An 850 rwHp Supra will NEVER get the looks that a loping Cadillac gets. It's total paparazzi.

    I have the ls6 with stage ll.5 patriot heads, ported tb, tsp 232/234 .595 .598 112 cam, kooks headers, cai, 25% under drive pully, monster stage ll clutch with the 18 lb lightweight flywheel ( mention because of rotating mass reduction) tuned by Jason at Texas Speed car made 440 rwhp and 445 ft torque all motor and 540 rwhp 540 ft torque on the bottle. I thought with all the crap the car has 440 was low.... But he says its where it should be..... like everyone always says no replacement for displacement.

    ----------

    The wife has a 2010 camaro ss 6 speed I just finished. Cai, 235/239 .639/.623 111 lsa cam, headers, 25% under drive pully, with 125 of the giggle gas. She drives it fine. Cam surge idle bucking and all. Who says hot chick's can't drive!

    ^ impressive ! Got a dyno sheet? How is it HP is not higher than torque? Did you decrease your rev limiter?

    I don't know how to read dyno sheets on nitrous. Are the peaks and curves the same? If so, it looks like you should increase your rev limiter to 7K rpm and dyno it to there. The bottom end can take it.

    He has plenty of torque right off the line. And the hp grows perfectly...

    Nice build, must go through tires like crazy...

    If you want more punch slice off the weight. Cf fenders, seats, trunk lid and hood...

    Re: 425whp LS6

    well....went for a baseline today on one of my buddie's dynos......car put down 348/340 on his dynojet. I'm going in a few weeks and dyno'ing on another buddies when both of them get together to tune my car. But i guess the numbers are decent for a stock car with JUST new mufflers..........no other power modifications have been done to the car

    Re: 425whp LS6

    Everything feels slow to me unless it's 1000+ RWHP and 3000lbs or less.
    400 whp on almost 4k lbs car is perfect for roaming around in my opinion.
    I'd prefer torque though (supercharger, headers, cam, intake, set up for torque). Nothing like having 400lb rw torque at less than 2k rpm so you can zoom away without revving the engine on the street.
    Modified Ford power stroke (or any diesel for that matter) with 60 psi 1000+lb torque is a blast to drive on the street, more than just about any car (except maybe the GT-R) imo.
    LS6 should be able to get 400 rwhp N/A, have a little torque loss though , so depending on your driving style you may or may not like it.
    Of course doing a big cam and all that will make it a pain in the #@$@ to drive at 5-10 mph in stop and go traffic.

    My 231/239 .598 .598 cam is cake to drive in traffic compared to my old cammed evo.
