boost questions for boost experts...
Vortec,
We did some flywheel hp tests with a 5.3 that was completly stock except for headers and a Rotrex c38 supercharger. I ran the pulleys for 9 psi and produced a touch over 500 at the flywheel. The 5.3 is a great engine in stock form and as you know will respond well to common mods.
Good choice on engine.
Sorry your thread went south.

My car makes 847rwhp @ 20lbs of boost. It also makes 847rwtq @20lbs of boost (what, 100 more than yours?).
This was also with a 218/218 114lsa cam (that's what a "small" cam is lol), and 357ci. Oh yeah, and an LT1.
The dyno wouldn't load the car enough, but estimating from it's performance at the track, it is probably right around 940rwhp @24psi. (right at peak efficiency for both turbos)
I guess I'm pretty happy with my inefficent setup that drives like stock and traps 149+.
As far as LS1's, the 427 in our shop car made 920+rwhp @16psi through a T400 and smaller cam than yours.
What was the question?

dyno queens!!! lol j/k. dyno results arent as significant as good ol' mph or et. you all should face off on the strip to settle it...no matter who's car has more power or is more efficient, that will tell who's dick is in fact bigger...
Takes alot more than a dyno queen to trap 149........Some numbers always tell the story.

so then, will we be seeing everyone in atlanta for the year one event?they will have a dynno AND a drag strip. i would expect to see all of the cars driven to the event. then we could check gas mileage to prove efficiency. just my .02!

Vortec,
You should call Terry @ Cam Motion on your cam question. I would try and keep the camshaft on the small side to aid in comfortable drive. If you can afford to change the heads to lower ratio that would help your cause also. You could probably get to 500rwhp with the stock pistons if you are carefull with the tuning, forged pistons would add a degree of safety. The 5.3 block can be bored to 3.9 inches to bring your displacement to 5.7 in the future.
Good luck with your project.

Bryan,
Not sure how I got off on this tangent. If you want to start another thread about it, I'll tell you everything you want to know about my car.
It just bothers me that you talk down to everyone, and yet alot of what you post is 100% bullshit. I just got here too late in the game to respond to it all.

This thread was created because someone wanted to know what their engine could do. I will repost the question on a new thread just for you.

I think I need a lobotomy to erase any trace of your thinking. Maybe we can get a group purchase on it!
LMAO
I almost fell out of my chair!

The car makes all this power
gets 25 mpg on the highway
does all of this on the stock pcm
passes emissions in NC, and by the way passed a tail pipe test
does it with no problem on pump gas, no nitrous, no water, no meth, no alch.and does so on closed loop.
you've made 1500hp motors. Surely you can explain to me what is so wrong about my setup seeing that I seem to be so retarded about it. All I can tell from all of this is that everyone is so hell bent on me not have going to the track. It is winter here and the tracks are closed, I dont have a choice.
Please feel free to dump on me here. Please also let me know who said this was the drag racers forum.

Your setup is the bestest ever. No one can touch it. You are a god. Is that all we have to say to stop you from "enlightening" us anymore?
damn this thread has gone crazy...i was just joking about you all going to the track. but if your goal in the end is to have a fast car, then track stats matter. no matter the efficiency of the setup, whoever gets to the end of the track first is the winner.
Explaining anything to you would be difficult at best. Lucky for me that is not my job.
This thread was about a turbo 5.3 for low dollars. You have filled it with worthless postings that will not help vortec7 in his quest for low dollar power. Your postings are interesting to me in a Jerry Springer trailer park kinda way, they entertain.
For that I thank you.

I would assume that you made that comment, because I chose to not have you build my engine and I chose to not have you build my engine because you said
"It could not be done and pass emissions" - remember that conversaiton? I still have the emails.
I had money in hand, Lingenfelter, MTI, and morgan motorsports all said it could not be done. There is a right way and a wrong way, I started with a very simple repsonse and others chose to jump my proven ideas. I was defending myself.
Well Jerry, I get the last laugh. Mr almighty engine builder. Based on what you told me, I am not sure that there is anything useful you could share. Its a shame because I had more respect for you than that. Not that it mattered what I thought anyway.

I guarantee Kurt has forgot more about forced induction than you will ever know.
The only SAD thing is that you are the only person that cannot see that. You CLAIM you make all this hp and do this and that, but I think you're full of it and I don't think I'm the only one. You're merely a pompous know-nothing who paints a facade of knowledge to cloud the fact that you lack any real knowledge on the subject.
Next time you want to post about something, don't!

One more thing before I go, I am not sure about Jim and his car, but you can bring your broken **** to charlotte anytime for hometown smacking.
You can shut the f*** right back up.
