400hp

This is a discussion on 400hp within the External Engine forums, part of the LSx Technical Help Section category; not an expert at this by from what I've seen. low 8s on DRs and decent launch. 8.2-8.1 in 1/8th....

    I cant see myself spending 1300 on intake/tb combo...I may run a small shot of nitrous (75) so would like a manifold that is set up for that and will hold it better than a plastic one.
    Any recommendations?

    What is a good cam for the street too? Anybody ever run the GM Hot Cam?

    from what i've read (i read a bit on here) there are a few people running the hot cam and seem to like it. when DD and cam go in the same sentence it seems that most people will recommend the 224/224 cam iirc. when i get my LSx I'll probably be looking to go with the 224 cam based on the posts on here.

    hope this helps a little

    my opinion is , port the TB for a little more flow and add headers from there do cam/valvetrain you will be a happy camper. Next step would be heads and intake manifold (FAST 90 is very popular, but as noted pretty expensive) , again, by what i've read.

    baseballny2, I misunderstood your question as you misunderstood my statement. Re-read^^^^^^^^^^^^^^^

    I stated that I have 340 rwhp which equals 400 flywheel horsepower!

    400rwhp on these cars is nothing out of range. My goal is 400/400 rwhp/tq

    The trick is getting the power to the ground and getting it in the low end.

    Some cars just have more power than others from the factory for whatever reason too. I've seen 98's dyno higher numbers than 02s with the same mods, and vice versa, it happens.

    True duals are a great way to go if u ever plan on adding major power adders like heads/cam/intake. If you aren't planning on doing that then you're paying a lot for a few extra hp. I have 338rwhp/345tq on my 99 with ARH LT's and ORY....a guy from my club has ARH Tru Duals on his 02 WS6, he spent close to 3'gs on them and only has 344/337tq ..alot of money you could have spent elsewhere for only 6 rwhp. I'd rather save $1200 and weld in two electric cutouts on the y pipe and go "tru duals" whenever I want. Just MHO....why spend 3 times as much to squeeze out a few extra horses when u can spend the same amount a get a much bigger bang for the buck.woo wooo
    Since this is going to be your daily driver i HIGHLY recommend going for a mild cam.


    Hope this helps

    True duals alone are worth 25-30rwhp. Some of these LS1s put down over 300rwhp stock. Add headers, and 330-340 is about right...

    Yeah I was thinking 60rwhp from a tune was far fetched. I see what you mean now.

    before you get all excited you should do all the external engine mods first ls6 intake, longtubes, true duals, under drive pulley, throttle body, lid, maf, freemods, a good tune, and other goodies see how you like it then with probably 350rwhp give or take. then go with either cam or nitrous from there.

    ^ Why do half the mods and get it tuned then see how you like it then put a bigger cam in and have to get it retuned? IMO do everything at one time if you have the money so you only have to get the car tuned 1 time-saves money/time.

    Or do the bolt ons as cash allows and then wait for the cam to get tuned. Bolt ons will be fine without a tune but a cam really needs a good tune.

    exaclty how much time does it take to install headers on a lift? I heard a few people say it takes as much as 8hrs while other say its really not bad?

    Thanks,
    Evan

    Would you guys recommend the SLP Ram air kit over the K&N kit?
