How much boost?

Bad detonation from too much boost can do that, but that's pretty gnarly. I've seen pistons with a hole burnt right through them and pistons with chunks taken out of the side, but that nothing chewed up like that without be complete peices missing.

Actually he says all the work was done by some friend of his, that he just bought it a couple weeks ago. Yeah, he really blew it with the 20-25 lbs of boost comment. Everything else was almost believable. Oh well, when I run him next week, I'll let you all know.

Ive heard that bone stock 5.0s hold about 10psi. But that is from a turbo, which is prolly more efficient than whatever 1337 supercharger he is running.

Remind him of how hot air gets when you compress it.

He isn't pusing 25psi. He is prolly pushing -1in Hg.

KA's can handle 20psi+ in bone stock form.

Yeah, but for how long? I mean sure you could probably make a couple of 11 or 10 second runs at the strip with it, but you won't drive it home.

Not even the LS2 in the GTO can handle over 10psi without floating the valves.

I don't konw how many runs he has made so far. He=elks 240 over on ka-t.org. He's made quite a few passes, drives it on the street twice a week(kinda like a guy who masturbates twice a week, make it good), and layed down 420whp..

Here is his thread http://www.ka-t.org/forums/viewtopic...er=asc&start=0

Sorry to link to another forum, but its for proof only.

Make sure you get a look at his trap speeds.

You guys are talking like 20psi is a magical number that only people who have a huge budget for their engine can attain.

We're talking on a 5.0 Mustang though. Hell, I'm running 22 psi on my Talon, but with the compression, it has no problem handling it. And this kid's talking about running spray, and that's a whole 'nother can of worms.

Some engines were made to take boost


The stang does a good job, but it really isn't

And you're talking like you run it all day long....on a turbo thats worth bragging about running 20psi on.

that is a 60-1 T04E that is being pushed to 27psi on a BONE stock KA.

supposedly theres a guy on stangnet or corral or somewhere that has a intercooled procharger running somewhere around 14 psi with low comp on the stock block.

The stock 5.0 block usualy cracks at 400 hp~ from what i hear but there are some people who seemingly reliably push 500whp out of the stock block which is good enough for a 10 sec 1320s. so i would ask him if he has the origonal block.
