LT1 Fuel Cooler?

Direct injection on many of the new high-tech motors already does this (new v6 Camaro for instance)...fuel pressures of over 2000 psi atomizes and cools the intake charge much more efficiently, thus allowing much higher compression ratios and 10-15% more HP:D Win-win! 
Somebody needs to invent a aftermarket DI cylinder head and fuel system for the LT1...can you say 14:1 compression on pump gas
That would be cool!

Ok...maybe 14:1 is optimistic...13:1 or 12.5:1 is probably doable. Why can't you make more compression on a LT motor anyway? LS motors get as much as 15:1 compression 
Don't believe me?!: http://www.gmhightechperformance.com..._ss/index.html
Somebody in the LT1 arena needs to step their game up!
^ That Camaro is Badass!

"The 3.6 litre (3564 cc) LLT is a direct injected version based on the earlier LY7 engine. It was first unveiled in May 2006, and the DI version was claimed to have 15 percent greater power, 8 percent greater torque, and 3 percent better fuel economy than its port-injected counterpart. The LLT engine has a compression ratio of 11.4:1, and has been certified by the SAE to produce 302 horsepower (225 kW) at 6300 rpm and 272 lb·ft (369 N·m) of torque at 5200 rpm on regular unleaded (87 octane) gasoline.

Prove it with real world examples. You obviously don't know much about new cars. Every engine I've seen that had DI added gained 10%+ HP over port injection versions of the same engine...at least that's what the manufactures say. I'm giving facts...the new camaros DI LFX v6 makes 312 HP while the SAME engine but without DI makes only 256hp in the port injection. Your pulling **** out of your ***!

And let's not mention any downsides to direct injection like this...

Sure thing... I'm sure DI was the only thing they changed on it. You lost all credibility when you said you could run 14:1 on pump gas with direct injection.

Dfi by its self is not the only reason for the power increase. New engines also have vvt using cam phasers and if they are DOHC they are varible intake and exhaust timing. New article in car and driver showed and interesting approach to fuel efficiency and more power. Basically it would use 2 fuel delivery systems. Dfi and port injection. E85 would be used though the dfi system and regular gas through port injection. E85 makes more power gas is more efficient.

you can use n2o or co2 with it.. wonder what the results would be
they also make this>
