Default High 11's

At some point I want to build up my M6 ws6 to run consistant high 11's. How does this order look. I figure I will do the research now to save trouble later. I would like to get it done with just bolt ons, but something tells me I may need a bigger cam. I am new to LS1's so bare with me.


4.10 gears
Magnaflow cat back--Already have***
Long tubes
SLP air lid
Bellows?? Prob a waste?
K&N's--***
FAST 92mm Intake Ported?
1.85 rockers
85mm MAF
Tune
Drag Radials

spend money first on a cam and heads before the intake track and the $400 rockers. I have a small cam and cheap heads and have an easy 11.5 in my car with some good tires.I have a ls6 intake and stock rockers. The rockers and intake will run you $1600 and with your setup will give you little.

Is it possible to hit high 11's with just bolt ons? I really want to set a good set of headers first to make it sounds mean.

Headers are headers. I highly doubt that your cars sound will greatly vary between different brands of long tube headers. However, there are differences in quality and overall fitment. Pick a header that stainless steel, thats what I would do.

First off, it's completely possible to run 11s with bolt ons. You would just have to drive the **** out of it, and good weather wouldn't hurt either.

For an easier approach, a cam would be your best bet.



Here's my analysis of your list:

4.10 gears <---wouldn't do much for performance, just make it harder to hook. And you're better off saving money for a new rear that wasting money on a shitty one.

Magnaflow cat back--Already have*** <---What do you already have? A catback will offer some gains. GEt what you want as far as sound goes, or just get a cutout for best performance and price.

Long tubes <---Good mod for power, there are plenty of opinions on here about the different brands but each will offer about the same gains. Get which ever you prefer.

SLP air lid <--- Lid is also a must have, again all about the same. Get whichever.

Bellows?? Prob a waste? <---definitely a waste for performance, they improve the looks but that's it.

K&N's--*** <--- I think they have been proven to not really show any gains, the re usability is the seller for me. If you got the cash for it, get it. Otherwise just wait.

FAST 92mm Intake Ported? <--- A good mod with a heads and cam setup, still only worth probably a few tenths, save this for last.

1.85 rockers <--- DO NOT GET THESE, they're not worth it at all. The stock rocker is stronger and lighter, and with a cam you don't need the 1.85s because you can have the cam ground any way you want. If you do a cam possibly look into the stock rocker bearing upgrade.

85mm MAF <--- not worth it. The stock isn't going to hold you back any til you make big power. A cam only setup would probably never know the difference.

Tune <--- Tunes are hit or miss, depending on where you get them. Here I always recommend buying the software and a good wideband and learning it yourself. Even if it takes a while to figure it all out. You'll be better off in the end, and you can even tune your friends cars for money if need be. If that doesn't jive with you, then do your research about the tuners in your area, if you have to drive 100 miles for a good tuner, do it.

Drag Radials <--- Some people go fast without DRs, but it seems more like a waste of time to me. They could be going so much faster with them.

Whoa. Thanks for the great response. Yes I already have the magnaflow and k&ns. Judging by your response I should go lid, long tubes, then a cam. I really thought the lower gearing would make a big difference? Are the factory 3.42's really that good for the power band? Thanks again.

No, it's not that 3.42s are that good, it's just that they aren't that bad. On the perfect fun either way, you'd probably only be looking at a tenth or 2 gain. But having more gear makes it harder to hook.

Also like I said the 10 bolt on a M6 car isn't likely to last if you're hooking a lot of power. Why waste the money on the 4.10s only to have upgrade later.

If and when you tear your rear up, then go with a more optimal gear ratio.
