It has a fully spec built motor all forged internals and cam, twin 62/66 precision turbos,true dual custom exhaust, upgraded LT4 fuel pump,lift pump  and injectors,LED head lights, icon Dynamics stage 6 suspension kit w about 11 inches of travel Dyno numbers are 730 rear wheel horse power and 689 torque but it's capable of much more with a more agressive tune. I was just unsure of how much the transfer case and tranny would hold up to consistently.

You need to use tap talk app for photos.
What is the low side fuel system and what train 6 or 8speed. There are guys with 850rqhp on the 6speed in single cab trucks.

What stall?

There is a high and low fuel pump in these trucks.  Not just the one by the tank (atleast ive been told  i havent dug to much into mine in that department)

Yeah I know there is a high pressure pump under the intake manifold and there is a low pressure or feed pump in the back. I'm out of fuel so I have ordered new injectors and HPFP. As for the low side there are some kits out there but a buddy is going to give me a prototype system to try.
My injectors pump and system is all aftermarket not lt4 parts. Good for over 1000hp.

Tap talk? Yeah I've tried over and over to post pics and it won't let me.. it is 8 speed and are they getting 850 to wheels or to the crank? Mine is about 830 to the crank as far as the fuel system goes I did the lt4 fuel pump lift pump and injectors.. it did decent w just the cam when I was at 600 rwhp as far as fuel but as soon as I turned it up it definitely needed more .

I have seen guys make low side kits for under 200 bucks and push 800 plus HP just with that . From what I understand the low side is what screws u . These new direct injection motors need alot higher fuel pressure than the LS did .

So correction I have the LT4 fuel pump and injectors and the in tank lift pump is made by Armageddon it's their 465 LPH .. they're the only ones I found at the time besides weapon X and if I remember right they were quite a bit more expensive

850rwhp they dyno tuned it. there are videos of truck. I'm unsure of the power level of the 8speed to be honest I would be a little worried about that trans stock in a larger truck. 

Oh he has the the low side because he maxed out the LT4 pump/injectors and cam. Here is his pic

8speed is a beast. It may have some issues in stock trucks, but it can hold a boatload of power, much more than 850whp.

 

I believe there are people running in access of 1200whp on stock 8speeds.

 

Don’t quote me on that haven’t visited the vette boards in awhile.

So correction I have the LT4 fuel pump and injectors and the in tank lift pump is made by Armageddon it's their 465 and yeah your right the stock 8 speed can handle the power . I've seen guys will full size trucks and even Tahoe's make 900 rwhp and be fine. I chose to keep mine tame at 730 to the wheels as I thought that was plenty for the tires I have and I was unsure about the transfer case holding up but I've since seen guys launch in 4 wheel drive and the t case is actually really impressive

I agree the 8 will hand more power. But it isn't as simple as car x did it so truck x can do the same. There is a lot of difference in a Corvette than a truck. More so a crew cab lifted 4wd truck with stock stall,axles,driveshafts,ect... and larger heavier wheels.
As stated more than the tires can handle. My tires are 12 wide and 33 tall, aired down,lowered traction bars spill spinning.

Good news is we are both turbo so boost controllers are a quick change and you can run more or less. No pullers to swap out.

My comments on the 8 speed abilities was more a issue of them being a bucket of trouble on the stock/gm side. Not knowing if he already had that ironed out or not.

Why I asked about stall. As I burned up mine at my power levels and my weight,transfer,and drive train are easier going on trans.

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
