It's cool man. You might end up being ahead of me. I'm just doing the research now. I think you and Eric will make better numbers on a cool day under favorable conditions.

 

You need to rethink your comment on this because direct injection motors like ours must inject fuel via 1 or 2 5ms windows. Duty cycles can not go higher than that, instead higher fuel rail pressure in conjunction with bigger injectors will be needed at some point.

Simply the nature of a new beast.

 

The king has spoken?

 

So how much room do we have then?

 

Well obviously when performing a turbo upgraded a few things need to be considered please correct if I'm wrong this has just been my acquired knowledge. More Air+More fuel= More HP. So bigger turbo means fuel delivery adjustments, ECU adjustments, intake and exhaust adjustments, and cooling adjustments. So hell I say most of those parts can either be easily fabricated or purchased. Nothing better than being a pioneer. I was considering doing a turbo swap as well but definitely need more knowledge of the tremendous little snails. I know I need to find a turbo that will flow properly for what I need, similar to you I would love to mess around with that 400 HP range. GM has put some good thoughts in this good reading I found, http://www.solsticegxpowners.com/for...ead.php?t=2325.

 

I don't know the answer to that. As far as I have read the answer lies in being able to track the fuel rail pressure and that may not currently be available. A lot of good research is going on over at the HP Tuners forum on this and other aspects of our engines.
