Chris, Did I miss where you said what size pulley you are running? Standard measurement or metric will be just fine thanks?
The smallest I'm aware of is 2.75" but I have read some reference to a 2.7"..........
thanks in advance

So yesterday, we took the truck to W2W powertrain to use their all wheel drive Mustang dyno. They have a brand new dyno that is just awesome. After about 3 hours on the dyno here's what we came up with;
270 rwhp (the way we have been driving it)
335 rwftlbs (same as above)
These were the results after tuning!!
413 rwhp
445 rwftlbs
Still only 5lbs of boost. This truck has 400 ftlbs basically from the time you go to wide open till you get out of it!! It feels really good now, it didn't before. I still would love to have the 10lbs we were shooting for.
Well we are headed to the track tomorrow, I will let you know how it does now!!
Thanks,
Chris

I ran into the same problems with IAT with my Radix but got through it, and the most I could get out of the stock motor and radix w/ 3" pulley was 433RWHP/455RWTQ.
I'm currently building a 427 w/ a Nitrous shot.
Good luck, I hope to see more updates.....

Why switch it now? Why not get some track times first to get a good baseline and then switch to the turbo and see what it can do?
