900 whp? why stop there....how about 1 million hp...hehe. I doubt that 900 hp will ever be reached with pump gas....hell, we haven't even seen an EVO with 900 whp on C16 yet (as far as i know).
Correct me if I'm wrong, but the limiting factor is the fuel. You can only cram so much fuel into a confined space (2.0L) before it auto ignites. The more the air/fuel mixture is compressed the more heat that is added to the mixture. Adding a more efficient IC will help reduce the heat from the compression and turbo inefficiencies. Larger turbos are more efficient and add less heat to the mixture as well, but at a certain point 93 octane is unstable. My guess is that the pump gas limit is between 400-500whp. The BR440 is capable of 400 whp...I'm sure the larger turbos (GT35, BR580..etc) are probably capable of a few more ponies but I don't think much more than that.

I made 375 on pump gas (dynapack dyno) on the stock compressor (upgraded Ti & 10.5 hotside) with my setup. I see Buschurs new hybrid making over 400 on pump gas easily. Before the header, O2 housing, and upgraded hot side on the turbo I pulled 12.5 @ 111 in the 1/4 on pump gas full weight (spare in the trunk etc).

Local customer made just shy of 400awhp on 93 octane and stock turbo. Ran 11.9@117 with best mph of 118.

Thats what I thought, Bushur's osofast eclipse is making some insane number no? Alot of people don't realize how ong people have been tuning this motor..its been around for what 10-12 years, no? (of course there have been slight advancments,lol)
Geo....what kind of numbers do u think are possible with a upgraded turbo on 93 octane?

Well 4G63 DSMs have done a tad over 500whp and that is with "small" turbos. Personally I don't feel comfortable running the type of boost you have to run to make 500+hp on 93 octane without water/alochol/methanol injection. I'm sure you could make the number on a dyno but I would be uncomfortable driving that hard everyday(top end pulls etc).
