13Ts are a better option for high VE setups that can accommodate more than 17 psi at redline on pump gas.

The rest of your post is entertaining but anecdotal. What are back-to-back quarter mile trap speeds for 13G and 13T cars with similar mods running 17 psi (which many consider a reasonable pump gas maximum)? Engine demand lines superimposed on the combined compressor flow maps suggest no significant difference.

Sometimes practice beats out theory. In theory they should be the same with 100% VE demand lines but in practice I haven't found any numbers that say they are. Even at 16/17 psi the 13t's seem to make more power crossing that 400 AWHP line.

Fastest 13g or 13c time I know of with no Nitrous is Matt Monet who ran 11.59 @ 117 with stage 3 heads, street cams, CFDS, aluminum FW, and volk racing wheels.

Typicalstate guy went 12.15 or something around there with stage 2 heads and dr500's.

Jet, JRod, Maddog, and anyone who has gone to the track with 13t's running 18 psi or more has seen high 11's to low 12's with traps in the 116-120 area. There are a few with low 4xx's on pump gas with 13t's running 16-18 psi then again thats all driver skill. I have been searching now that you bring it up and I am looking for a 13g setup that has hit 4xx on pump gas. I remember darthstimpy made 417 with dr500's on a custom unichip stock heads and cam IIRC setup running 18.5 psi. Don't know of any 13g setups to do it though.

Found lanes old thread What is the 13g horse power record?
