How much boost?

Ok, I know bench racing is taboo here, so I'll try to keep this copasetic. Ok, so my girlfriend's dipshit ex is talking shit about my Talon, big deal. He claims to have a 5.0 stang with a voretc blower, Holly intake, roll rocker arms, cam with 500 lift, MSD ignition, and inline fuel pump. Just now claimed he ran 9's with nitrous, and a bad launch and shifts. LOL! this guy is great.

Ok, so I know he's most likely full of crap, but I do have a real question here. He claims to be pushing 20-25 lbs of boost, which he just turned down from god knows what. Can a 5.0 even handle that much boost without extensive engine work? I'm assuming this guy's most likely talking out his ass.

His best quote so far now, "im a street racer i dont do much on the track"

LOL!

Anywho, if you all could give me a bit of info, that'd be great, I don't know much about V8's.

Thanks

Don't know much about 5.0s, but almost no NA engine can handle 20-25 psi boost without extensive supporting mods. Running 9s costs a LOT of money, does he look like he would have 10s of thousands invested?

He claims the 9's were timed with a G-Tech on the street. I'm pretty sure he's full of it, but some of the stuff he says is pretty damn convincing. Also, what RPM's would you launch a car that fast at? He claims to launch at 6 grand and not break loose on slicks.

Probably bs

He's full of it... Don't worry about it, he's got penis envy cause you're sticking it to his ex... and he's not.:thumbsup:

LOL! Yeah, and my ma's out of town for the weekend (yeah, I'm living at home for a bit at age 21), it'll be fun ;). I'm probably gonna run this guy once I get my ACT 2600 installed.

The most I've even heard of a Supercharger even blowing was 21, and that was a Whiple on a Cobra....

hahah he g teched a 9 second run on the streets. lol what did he do for brakes and suspension cause he should've died doing that one run. i don't think you understand what the trap speed is on a 9 second car. he would have to be going between 130-140mph in the 1/4 mile. if he had a import he would have to be going 150mph.

with the powered required to go 140mph in teh 1/4 his stock rear end would've ripped out of the frame cause the 4 link is very losely connected to the chassis. not to mention the axles would snap and he would be doing a pretty big wheelie.

He claims he has a 9 inch posi-rear and the front comes way up on a launch. And yes, I am fully aware of what a 9 second car is like. I'm sure he isn't actually running 9's, just trying to see how much of his story is true. I'm hoping it's all BS and that I'll stomp his ass, but if he really does have a blower and N20, I'm screwed.

Does your talon happen to be a tsi? Just wondering.

The guy who runs the muffler shop I go to used to drag race a lot at the track in Commerce, GA in a fox body mustang with a fully built motor with vortec blower and he ran high 11s/low 12s. I'm not sure if that was on the spray. The guy is full of it...

If your going to spend all that money to get your car to run 9's why wouldn't you go to the track to get your times checked...

If you would have said 10-15 i would have been skeptical.

20-25psi???

Most likely feeding you some BULLSHIT. To run just 14+ lbs of boost on a stock block the internals would all need to be replaced. I mean 95% of the stock parts would have to go. Then, with the power you'd be putting to the block itself would be just about maxed out from the power/rpms to the point that it wouldn't be. My buddy had a t-trim on his fully built 5.0. It had an 8.0-1.0 CR and was pushing the limits of safety with about 15-16 lbs of boost on the non-aftercooled setup. It had around 470-480 rwhp or so and was good for low 11's, and the jump from 11's to 9's is a ton of power.

If he said he was an intercooled t-trim with fully balanced forged internals with 8.0 to 8.5-1 CR running 15 lbs of boost, a 550+ lift cam and a 150-200 shot of the giggly, then I might believe it. But, 25+ lbs of boost is nuts. You'd need a DSS prepped block with a gurdle to even think about that.

Here's something that could help you find out...how long ago was your g/f with him? Was she around when this "9 second" 5.0 was being driven/built?

She should be able to give you more answers than anyone.

What's the story behind that piston?

What's the story behind that piston?

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.php?t=3319&postdays=0&postorder=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

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

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.
