Listen douchbag, I'm not here to please you. I simply replied to a thread. If you don't like it, go **** yourself. Have a nice day.

 

Well... After reading through this thread, it is now easy to see why so many of you guys are stuck at 800whp when you have 8 cylinders and 5.3 liters to work with.

In the mean time, I will be out making my 600+whp with only 6 cylinders and three liters to work with.

 

Dude you are ******* retarded

And you seriously need to learn how to read a compressor map

 

People arent stuck at that HP level, thats pretty much all a stock one can handle. And the reason you dont see high HP 5.3's is untill recently I think there was a lack of off the shelf parts to build a forged one. It would be cheaper to bore it out and build a 5.7 than have custom pistons made for a 5.3. The cubic inches is totally irrelevant and has nothing to do with why.

Is your 6 cylinder 3 liter all stock? I would hope so if you're bragging about it, my last stock 5.3 (cam only) made 640whp and ran it hard for 3 years. Another one in my friends BMW is making almost the same 99.9% stock, stock heads, stock cam, stock intake, .the .1% is the valve springs were upgraded... thats it.
For a $100. junk yard engine and a reliable 600whp daily driver I'll take every bash anyone has against it and smile.

 

There are multiple 2k hp v8s, good try though.

 

you're an idiot. YUP a promod 88 flows as much as a mp t70 @ 10psi.

 

good to see some good numbers. my car is going to be tuned tomorrow well see what it does.

5.3/317's/4l80e/3400 stall/3.73rear/mpt70/96ar
224/224 116lsa 580/580@50 comp 918 springs

i do see the lower compression problem kinda ******* the car a bit but with gas prices i deal i with it.

update tomorrow

 

look in the mirror plz.

 

Oh man... Please go read the whole thread. I thought it was clear that I was being SARCASTIC in that post, but apparently EVERYONE missed it.

I am well aware that a small turbo does not flow as much as a big turbo at the same psi. If you had read, you would have noticed I was trying to explain that very thing to people both BEFORE and AFTER that very post. Yet you decided to jump on the hating band wagon even though I am on your side and you didn't even know it.

Clearly this 45 trim T3 turbo will not flow as much as the T70 turbo at the same pressure ratio. I'm not going to be sarcastic anymore, because people don't seem to understand it. People, please read before you guys jump on the hating band wagon... That's all I ask, just read...

 

as long as this was sarcasm too, i guess you're alright.

 

This is perfect. This is what I was after. From what I read, nobody mentioned this was all on stock internals. This is great! That is exactly what I was saying. They should be capable of WAY more than 800whp. It is retarded to think they CAN'T do more than 800whp.

The original poster SPECIFICALLY SAID AND I QUOTE... "What did you do to get it (cam, forged, heads, turbo size)? "

I thought people were simply maxing out at around 800whp on built engines like the original poster asked for. Stock long block wasn't even mentioned until post #11. That was just one guy though. Then another guy was talking about a forged engine that he got to 780whp.

This whole thread has gotten blown completely out of proportion simply because people are refusing to read. They just skim through what looks good to them.

 

Of course it's sarcasm! I read through LS1tech and there are guys building engine's to make 2500whp! That is why I found it EXTREMELY hard to believe people were maxing out at 800whp. I KNOW these engines are capable of more than that, as I have researched it! ****, that's why I bought one to replace my tiny 3.0 liter man! LOL The LSX platform is simply amazing!

 

i was in this thread to find the limits and what people pushed the 5.3 block too. Glad this stayed on topic.

 

not so much "maxing out" just... making connecting rods bend in shapes that renders them useless.

 

Just a FYI Satan 95% ppl on this forum using 5.3s are stock internals, if you spent your time here reading instead of trolling you would have figured that out already

 

anybody out there run a procharged 5.3? I would love to see some numbeers on those.

 

with a locked converter you should make some great power

 

The OP asked about forged rotating assemblies... I did read. It is because I read it and others DID NOT, that I got backed into a corner. Maybe the thread title should have been "What power are you making with your STOCK BLOCK 5.3...?" Then people could feel free to jump my **** for not reading.

That being said... right around 800whp is maxed out for a stock block 5.3. That seems to be the common answer. Did this also include the OEM harmonic damper? I would imagine so, but who knows? Are the ring lands the first thing to go, just like on most OEM engines? At what point does one start to bend con rods?

How much power have people made with low silicone forged pistons and forged bottom ends then? On the same 5.3 of course.

I understand that it is easier to buy off the shelf 5.7 pistons and bore it, but a piston manufacturer will make you any piston you ask/pay for.

 

must say the 5.3 is tuff

 

people have made roughly 725 to the wheels, 650 is very common. here in the v8 world is not called STOCK BLOCK, its called stock SHORT BLOCK. meaning the rotating assembly. rods (we call them rods, not "con rods"), pistons, rings, wrist pins, crank, and bearings.

if anything lets go in the 600-675whp range its probably going to be the ring lands, and its probably because of the tune (detonation). if anything lets go at 675+ its probably gonna be the rods bending from cyl pressure. and yes, most of the time people are running stock dampners at this level.

now, with forged internals you can make probably 1400+ hp, it depends on the build and mostly everything around the short block. the factory GM block itself can probably be taken to 1700hp or so with a bit of work, its been done with the 6.0 block and these have much meatier bores.

stock short block 6.0's have made over 800 to the wheels.
