Twin Charging my Z!

just look at it this way the piping that sasha uses in his kit technically should be impossible to flow more then 500 hp(charger piping) but binder is well above that. its because once its compressed the volume aka the space the air takes up is the same but the density or weight is much greater. 1 cubic foot of feathers and 1 cubic foot of bricks, same volume definatly not the same density.
So 76lbs/min is about what a GT4094R can push. So even if the air was not compressed, it is still enough flow to make the power that binder made.
Now, once you compress the air, that number (flow) goes up significantly. I don't think there is a turbo I can fit under there which will reach the flow limitation of the 2.75" pipe. Heck, 2.5" piping would do the job just fine.

hmmmm my bad i thought it was a lot lower then that, you have anyway to determine velocity of compressed air sasha? i dont think it would be a issue though the clearances in these blowers are pretty small even on a lower efficiency blower. its not like a wide open throttle body air can freely flow through ive never taken a m62 apart before but a stab in the dark i would imagine the clearance to be under a quarter inch.
the op really shouldnt have any issues with a setup like this, like i said its been used numerous times on other platforms.
if you want a great example take a look at the lancia delta s4, they maxxed the supercharger out on that thing at 350 hp, so they threw a turbo in as well, cant find anything on the specs outside it being a KKK turbo but it looks to be in the size range of gt35 or smaller so nothing monsterous. yet despite that in the endurance tests to see how the engine would hold up they cranked the boost up enough for both systems working togeather to make 1000 hp for extended periods of time on a 1.8L, not sure if that is wheel or engine though. neither system should have been able to support that power level, and the thing was quick 2 second 0-62 times granted it was a light car.
edit just found the specs and the turbo used on the lancia was a KKK K26 which is roughly equivilant ot gt25-gt28 depending on setup, max's 300-400 hp again depending on setup. so they where able to take a 400 hp max turbo and 350 max supercharger and push that thing to 1000 hp (im guessing the 1000 is at the engine.) on a chassis dyno for extended periods of time.

My plan for the stock is to use it as my guinie (spelling) pig. I know there are going to be plenty of issues to work out with this setup in its birth so I plan on keeping a very conservative boost on it at the beginning until i feel confident I can turn it up, at which point i will build the engine.
In regards to cooling. Do you guys feel the intercooler that comes with the PL kit is sized appropriately for such a set up? The only other one i was considering was a Treadstone V12. It is 22" X 12.5" X 4.5" (.715 cu/ft) and would fit. However, the one in the kit is 23" X 12" X 4" (.639 cu/ft). So I dont know if its worth it to fix a new IC to this project for the minimal gain in cooler size. Unless of course Treadstones quality is that much greater to make some sort of an impact. Any input?

for sure i definately wouldnt try it with a stock block personally too much risk to all the systems on the engine when it blows. also traction will be a major issue since people are already having problems with large power levels, providing it a little bit lower is going to be problematic. although something that could potentially be fun if someone wanted to experiment would be a rb26 stroker with full awd drivetrain and a setup like this lol.

definatly build the engine first though dude, like others have said its too big a risk to frag the engine, because theres a good chance of fragging the turbo and supercharger also then your out a whole bunch of money and at square one. untelling how much power the awd g35 drivetrain would hold i was thinking mayby gtr rb26 and drivetrain togeather since we know that drivetrain can hold power.

i'm imterested to see how you are going to fit the blower belt assembly with the powerlab cold pipe the runs across the top of the radiator.
I think that a BP mid mount setup would be WAYYY easier to assemble, since there is nothing in the engine bay. Plus their kits are cheaper and more updated than the Powerlab

Edit: Looks like OP changed his location from Phoenix to Denver. Probably because nobody here in the local AZ VQ community knows who the fawk he is.
OP is definitely a troll.

One of the biggest hassles is going to be fitting both the front mounts on this thing. It can be done though. I also will have to reroute the Water/cooler pump and overflow tank. But other than that this all fits under the bay.

instead of running the heat exchanger up front mayby run it under the car somewhere with a massive fan, ive seen some of the porsche aftermarket systems do this to pretty good effect. just make sure its a good fan and mayby a bigger heat exchanger.

Thats not a bad idea. It would cause for alot of newly fabbed piping but maybe worth it. I am concerned about the radiator not having enough free flow due to the wall of intercoolers in front of it and the limited space the fans will have to flow air, even with upgraded fans if the air space is restricted it wouldnt help.
Do you think the V12 I had mentioned would be a better IC?
