something fishy here......
the guy is something else, he actually tore down his motor cause he was currious to see what the internals looked like after so many abusive miles.

not bad quik for a stock 4.8 with arp rod bolts pushing over 700 plus
gotta make you smile pretty damn big i would say !!!!
like he mentions a good cool motor and dead on tuning its amazing what a small cubed motor will do !!!

+1 What the 4 people above me already mentioned.... and ya all crazy if you think its a 5.3 with anything else done to it other than what he mentioned. His knowledge n tuning info make him a valuable asset to any community. 
So is quik the same guy as Rick or two differnet people? 700 RWHP is still far from 850 RWHP. So it seems the concensus is that the motor actually made the power "once" and never sustained that power level. THAT is more believeable. But for the same reason the speed records need 2 runs to be legal a once fluke power reading on the dyno doesnt prove that this setup on another stock 5.3 will make the claimed HP levels. The Z06 we dynoed hit 589RWHP once and the very next run without changing a thing put down 567. SO I still say that the claimed 847RWHP is maybe a one time fluke and the OP's claim that the kit will make that power on my stock 5.3L is totally bogus.

Rick is one of the best tuners in the country. The man knows what he is doing to say the least.
As for dyno numbers being altered? Highly unlikely. I know Rick very well, and I would trust what he says.
18 psi on twin 3071s is 800+ rwhp.
Its the real deal, no doubt about that.

The best tuner in the world can't over come physical limitations of parts. So we established that it is possible but not probable and that the power level was probably a one time fluke and not sustainable. Sounds like a good basis to try and sell some parts. 
Just like a GT42R can make 900+ rwhp on a Supra, but has a hard time making 750 on an LS1.
Its real. Believe it.
I agree, its legit. I dont know Rick, or louis more then the occasional email or pm either.
Many people believe "good" parts are needed to make power. They are not. The physical limits of the parts are much much higher. The limits come from making a mistake. Read some about f1 engines, detonation and the streeses on the parts. 20 psi under controlled combustion is a negligable rise in stress, but when uncontrolled combustion happens the stresses go up by the square root.
On a side note, the express awd.....is making around 700 crank....day in and day out at 15psi on 91 and meth. It weights 6600 lbs and goes mid 12's now with an oem 5.3. Its got about 11 k miles on it now turboed. It also is on a road trip right now, as a loaner....a friend borrowed it to pick up people from out of the country and their luggage. To bad the airport is 300 miles away. And in so cal, its more like a low 12 sec full size van.
If your a good tuner and good at monitoring yes, its completely possible. Just dont make a mistake.

Not making a mistake is definatly key. Our 5.3 T70 motor busted a ring land when the fuel pump uncovered on a launch for a split second. That was at 16psi and 17 degrees of timing. That motor makes 680 at the crank. As far as math, yes one of those turbos will produce 54 lbs/min. A 5.3 L @ 6800 rpms is going to use around 78-80 lbs/min. So I don't see how it is possible with stock heads to exhaust the excess pressure. Boost is wonderfull at over coming stock crappy intake ports but if you cannot get the gasses back out then it will eventually flat out at a certain power level. You can ram 104 lbs/min into it but if it only exhausts 87 lbs/min then you have reached your power limit. 1000 CHP is more easily achieved with a 6.0 with 317 heads and larger cubes. I havebt done the math on a stock 5.3 head to see if it is possible to flow enough CFM to allow this power level.
Theres an old saying from turbo buicks.....turbo overcomes all.....
The number you quoted for exhaust are at 1 bar.....the exhuast port flows more due to boost also. A turbo buick head flows what 75 cfm? and can make 700 out of only 6 cylinders. The block may split into two seperate peices though. Nice internal parts too....lol
Take a horrible engine, put an ok fuel injection system on it, a good spark control system, a turbo, intercooler and look out........thats the turbo buick way.

haha! Yea thats true. A friend of mine runs turbo buicks. If you get all of the internals tough enough and the bottom end girdled then you wind up spliting the block through the webs! My math skills aren't that good. Maybe I will give myself some home work and see if I can prove / disprove my own BS through math. This should prove interesting!
