oil squirters are to keep the pistons cool. leave a squirter out of a 3406 cat engine and you can kiss it goodbye after a short time. ls9 is supercharged with higher compression in which the piston would benefit from having squirters. the precombustion chambers are bfor mixture of fuel and to keep it centralized to not spread it that would just cause a hot burn. direct injection is in most diesels and work great. its about darn time someone put it together in a new performance gm.

The use of piston squirters in direct injected engines is to cool the pistons because of the lean mixtures used under certain conditions. I don't remember the reason, but I believe that oil squirters have been in use on the high feature V6 prior to the direct injected models. I was also thinking that the LS7 had squirters, but have not been able to verify that yet. Something that was quite a rarity was having to perform any kind of repairs on the bottom end of the high feature V6 engines or the LS7. GM has been a little slow to adopt "newer" technologies to any of it's performance engines. They have been making flex-fuel vehicles for years now, but still they don't offer the capability on the corvettes and camaros.

Thank God!

The "High Feature V6", the 3500 used a single piston squirter for the 5 and 6 cylinders. It looks like the squirters can be added to the other 4 cylinders and is why I have some just for that very reason. ;)

The 3500 V6 is in the high-value V6 line. The high-value V6 line is just the latest version of the long-lived 60 degree V6 platform that debuted in the '80's. With the exception of the twin-cam 3.4 used in W-bodies in the '90's all of the other versions were a typical pushrod layout with 12 valves. There was of course the twin-cam 3500 V6 that was only around for a couple years that was based on the Northstar, but they are pretty rare. The high-feature V6 debuted in 2004 in the Cadillac CTS, and while it is also a 60 degree engine it shares nothing with the old chevy 60 degree V6. The high-feature V6 is an all aluminum 24 valve double overhead cam design with variable valve timing. The most common displacement is 3.6 liters, but there are 2.8, 3.0, 3.2 versions out there. The piston pictured above in one of my posts is a direct injected 3.6 piston. Direct injection was also something that never made it to the high-value line.

I know that you aren't a big fan ethanol Mark, but you do realize that in an engine like the LS3, LS7, LSA, LS9 or the "new" LT1 running E85 would help to coax a few more ponies out of them ? A perfect example of how E85 can improve a sports car's performance would be the Koenigsegg CCXR. It is a flex-fuel capable supercar and quite a monster making a stout 806hp on gas, but puts out a whopping 1018hp on E85. That is a massive 212hp increase just by filling up at a different pump. Granted the CCXR is twin turbocharged, but higher performance N/A engines do make more power with E85 too. Most of the issues that plague E10 aren't a concern with E85 and corrosion isn't a concern because these vehicles are designed to be compatible with alcohol. Since there is 70-85% alcohol it would take a boatload of water to ruin the fuel and I don't think that phase separation is a problem due to the small amount of gas and/or other chemicals that make up the remaining 15-30% of the fuel.

Dream car! *drool*

It's not that I am against ethanol, E85 and cars designed for it show great results... if you can push enough fuel through you can obiviously make more power with more octane. But it still get's less MPG...

My issue with E10 is it was forced on us while the majority of vehicles were only marginally capible of using it without damage or running lean. Fuel milage also suffered, cost didn't go down for us/end user but our milage did while oil companies reaped benifits of goverment reductions of taxs etc... but the real issue was corrosion damage to even older vehicles, rotten wasted lawn equiptment etc...

I totally agree with your opinions about E10 and the inevitable E15. I have been suspicious that some of the negative effects have been played up a little by some in the auto repair industry and also in the chemical additive industry for the purpose of profit though. The reduction in MPG when using E85 COULD and SHOULD be offset by lower cost, but the cost stays inflated due to a few factors. The largest factor for inflation is the simple fact that only certain gas stations have spent the money to install new pumps and tanks for it and they can jack up the price because they don't have any competition. I have decided that as long as things stay on track my house will be paid for in 4 years and I am going to build my own distillery in the back yard and make my own fuel.
