LT4 fuel setup on e60 would be good for 620ish. Dynos vary. Maybe a little more. I am not sure the octane limits for 91. If you are having belt slip issues, you might go back to a bigger pulley, lower boost and run full e85. It will make the same power. Remember less boost also reduces fuel system demand.

I'm planning on doing a Whipple with LT4 injectors, LPE pump, and E85. Gonna run the supplied 3.5 pulley and go from there. I am not worried about a power number. I may drop back to a 3.625 depending on traction. I want useable power on the street. When I drug a 850whp Hell cat from a dig this past summer because all he did was smoke the tires, It changed my perspective on things a little. Everybody gets caught up in power numbers. I am more concerned about making the car put the power to the ground. That is why I am still bolt-ons...still getting my current setup sorted and tuning dialed before I throw more power at it.

N/A is a good option too...for me it's either PD blower or Heads/Cam NA setup. I have had Procharger stuff in the past and they are ok. After driving my brothers C7Z I was sold on PD. I like the Maggie but couldn't pass up the stellar price I got on the Whipple.
