FI for auto x

[reckless]

ok, so I've got a 3.4 and I know Kronos JUST posted this but he's doing drag and I'm doing autocross so it's a little different. Not only am I wondering if a tt would be better since there's more stop and go (I'm thinking that there would be a lot more low end driving than in drag, am I wrong?) but as a whole the board seems to be slightly against a twin for the six. Or would a super be my best bet. Y'all are the experts and I'm still learning so help me out.

i t3/t4 like tiago had on his kits would prolb work really well for auto cross...

jsut like anyhting its all about sizing for your goals

no, a turbo would most deffinately be better for auto-x since if you size the turbo properly you will never get out of the boost. A centrifugal will never reach full boost on an auto-x course since you almost never reach peek rpm. as for twins vs single either would be fine and neither would have a big advantage over the other. if you are getting into auto-x i would suggest suspension before anything else. here is a link to what you really need to be working on http://robmeadway.com/fbodysuspguide.html

I think a blower would be better for auto X. You'll get boost through out the entire band and low end torque at lower levels as well. Blowers have that 'always on' feature that should help more in autoX. A small turbo could work I guess, but I still think a super charger would be ideal.
T-Punk is right though, suspention and chassis mods are a must first.

once the turbo is spooled it stay at full boost with no other RPMs needed for more boost

I got FTD in the modified class at a local f-body autocross running a 3.8 with a Powerdyne, up against the v8's a couple of years back.

in my experience with autoX, chargers seem to be the normal FI to get. this is about the only time I'd say go with a super charger.
