my log manifold for lsx sonoma. heres my manifold for my 99 gmc sonoma,
truck has an lq4, 4l80e, 12 bolt.
simple build motor wise... rod bolts, ls6 cam, pushrods, pac 1518s, timing chain, 73 lb/hr bosche injectors, 2x255lphs, -8an feed, -6 return, aeromotive brfpr,
tc78(1.15a/r) 50mm jgs wg, 56mm jgs bov, 3.5" dp, 12x24x4" a2a front mount.
id like to push the truck into the mid 10's with this log. we'll see how it goes.

Cool, I am always curious to see how other log style systems perform!

Stock48 i hope your right about the e.t.!!!!! ive followed your success closely over the years.
the a/c thing could probably be over came, it was more of an issue with the air to air inetrcooler and condenser than it was the pump or acc. drive....
maybe you could keep it and do remote mounted air to water or just spray alky/meth/water...
i think i am gonna try to lighten the truck up with some simple obvious spots for now, like the hard toneau cover and maybe a glass hood...
if i can get it down to under 3500lbs with me i think itll have some pretty good potential.

what are you using for the other side mani?
why did you decide to go log over using c6 mani's flipped?
(You would get less turbulance and better flow out of exhaust manifolds but at least you have the piping curved some and not 90* into the log)
good luck with the build, keep us posted!

The primaries "Y" into the main pipe.
This is just like I built for my turbo set-up and think it mimics a stock manifold.
The stock manifolds are short primaries that feed into each other.
Looks great in my opinion!

That log will support more than enoug power to push that truck into the mid 8's with the right set up. Some logs are terrible but nothing worng with a nice forward sweeping log like that.

thank you guys i have a couple more pics, ill try to post em tomorrow...
i think on a conservative tune (timing and a/f) on race gas im gonna try and push this at 15 psi and see how fast it'll go....
the big part im unsure of is how it'll leave... i dont know what it will 60'... obviously im not building it with the best e.t. in mind...
the 4l80e isnt the best and itll just be foot-braked, 3500 stall and cal-trac'd rear suspension..
if it will 60' in the 1.5X's i think it'll run a good e.t.
(and if its a dog in the first 60' itll be getting the wet nitrous kit back on it from last year...haha!!)
