what he says is pretty true i was at street legal drags one night last year and took a 2.2 eco 2 car lengths with out my nitrous on a 1/8th mile tho

I have a bunch of parts laying around, waiting for the weather to be half decent

cobaltss.net isnt really smart, its alot like here people dont do common sense mods and then hurt their stuff and blame it on gm

Ya, i was sorta seeing that with the "problem with the intake manifold" stuff.

Tom (wrenchmonkey) just got his, Nice ride. when ever someone come in they always talk to me about getting the GM upgrades.... guess word got out around here.

But watter injection is ALMOST a must with a Eaton. great units though.

maybe ill see ya again this year.

the reason #4 goes is because of number 4 flowing more air than the other 3 and when your running a leaner AFR like 11:8 you can see no knock and if running a smaller pulley with no cooling mods it will crack the piston, cool the charge properly dont run the blower past its max rpm and keep the AFR around 11-11.3 and your just fine

IMO its not the intakes fault, its the "dead head" fuel rail.... same reason why SRT4 guys switch out.

You mean returnless fuel system? I saw on cobaltss.net that someone changed to a return fuel system. His reason was because of fuel starvation in the injector farthest away from the inlet.

blower swaps and turbos are less affected by this issue and can run leaner with no issues

theres currently a turbo LSJ making 421whp on a totally stock motor just swapped out injectors
