ran 10 psi for 3 years never got too hot tho but im pretty sure it had something to do with the boost, other than that idk

how many miles in three years?

stock piston? How many passes? How much power? Just curious. 3 years may have been a lifetime.

Damn, that got hot, (lean)

prob. 20-25k when i bought the car it allready had the procharger pushing 10 psi with only fuel mods so...... it seems the person who built the car just wanted to take it to the strip beat the **** out of it and sold it. got it from a car lot btw. me beeing even more of a newb than i am now not knowing anything about boost vs compression, detenation a/f

yes stock piston unknown passes but i did see him run it .. way before i knew i was going to buy it roughly 500 i never had it dynoed i am acctually pretty suprised it lasted as long as it did

damn that sucks but that stocker was doomed from the getgo.

hmmm...makes me rethink boostin stock internals lol

IMO,

Anyone who really cares for their car and wants to increase hp above about 85hp per litre should consider forged pistons as mandatory.

They should also consider fitting the pre 2001 LS1 steam tubes that go to all four corners of the cylinder heads to help vent #7 cylinder which always runs the hottest.

Well not only tune is important. The fact is running 10 psi or ANY boost will degrade the internal short block over time. #7 seems to be always the one to go 1st but like said, you have a chance to rebuild with forged pistons and better rods and with proper fuel mods and tune, it will run fine and you could prob up the boost and the motor will love it.

Stock carnk +6.0 block+ forge rods and pistos=370 ci Add boost to that and if the fuel system is in good shape you should see 600+ hp.

thats actually really a stupid statement because a lot of oem vehicles today will pass up that number and they continue to run over 200k miles

This is an opinion only.
The last time I checked, the public were allowed free opinions on any public forum in the free world.
Where did you come from? ....some dictator state?
Or are you a natural born bigot?

You definately get zero for diplomacy and tact.

How about listing all stock production car engines that run more than 85hp/litre, are fitted with cast pistons and validated for 200,000 miles, big boy.

FYI its not strictly from running hot. It runs hot because #7 tends to run lean because of the intake design the back cylinders receive more air than the front cylinders. So in definition yes it is running "hot" in that cylinder, but what destroyed it is detonation because it went lean in that cylinder.

The manifold is not the culprit in that case. Someone has turned the manifold around completely and found that the #7 and 8 pistons were still the most prone to lean conditions. It is theorized that (as was said above) the steam tubes may be more of a factor than anything else. Whatever it is, its not the manifold. That has been proven already...

To the OP- that sux man. But its happened to most of us here in this section of the forum.. Welcome to forced induction world Now go make it bigger and badder than it was before like we all do with this disease
