whats the advantage of the poly dog bone mount?

f3racer

83% drivetrain loss seems like an aweful lot.

ls4door

Haha I think he mistyped or is being sarcastic. Otherwise you would be only about 60 whp

LOL! Yes, error on my part.

That's what I multiply by (0.8333...) to avoid subtraction and whatnot.

~17% it is, lol

there are guys dyno'ing with headers and all that reporting like 260ish whp. idk

2005gxp

yeah, the op was saying something about 300whp with those mods. for one these cars are deffinatly not track car at all. more highway monster than anything

I don't think 300 whp is possible with the stock intake manifold being N/A.

107 mph is about 310-320 whp though...

Really? I am down for the intake swap since I am getting the headers (might as well get the full potential out of both). Now that you have done the legwork and put together a post, I feel much more comfortable doing this swap with a buddy who is more mechanically inclined than myself. I am no dummy when it comes to cars, but I would just feel more comfortable with someone who knows what they are doing and has done this before. BTW, David, do you have the ls1 or ls6 manifold? Which is easier to retrofit?
At this point guys I am doing the right justice and researching all my mods and how much work(and money)this is going to be in order to reach my goals. So from my understanding, these are the current parts that I need to reach my goal.
1.8 rockers
Transgo or Thrasher shift kit
Comp 918 springs
Chromoly Pushrods
Electric cutout
Intake (ls1 or ls6) probably going to be ls6 because of gains in higher RPMs
Headers
Tune (found a local LS tuner that has a great rep around here and is cheap)
Polymount
(no stickies yet, I want to try to get this on street tires)
What else can I add????????

Right now i am using the ls1 intake. I have a ported ls6 that should be coming in tomorrow.
You'll be low 13's with the mods you have listed above. If you ever plan on caming then then get the ls6 intake. I like the ls1 cause its cheap and works great. Huge difference in power compared to stock. Im trying to get dyno'd. I went down to the shop and they have shut down. I want a baseline before i do my cam swap

I really am on the ropes as far as a cam swap for my car. Not too much out there to support the means of going that far with these cars. I know that this is as far as I want to take it now. Which intake would you recommend? Why? Which one is easier to install? I know the f-body guys pretty much all run the ls6 because of the larger gains in the upper power band. That is ultimately where I want to see it. Oh yeah! I forgot about adding a shift kit......****@!@!@ more money!

If u are trying to make a list look at my sig. I think i have everything u need on there to make our cars a beast as far as n/a goes. I am also putting a book together of each one of my mods and future mods with pics, discription, and price so when i head out to shows and whatnot i can just lay it on the front seat so i dont have to sit there an explain everything to everyperson.
