Well it's close just waiting on the intake and ECU. But i need to leave for work for about 2-3 weeks so nothing will happen before I get back.

To my knowledge i have not ever seen a roots blower on an ls1 platform? I know this is BDS blowers 1st ever build so they tell me. They are wanting some information on everything we do and dyno #'s etc. That's why we have no idea what to set up the blower at for boost??

interesting build . im curious how well the injectors will work like that but im sure it will be fine since they sit on top of the blower not post blower pointed into the chamber . although unsure if puddling of fluctuating comanded afr's will work.

and to the person who said h beams are better than i beams . you have alot of learning to do .

I think those blowers need fuel running through the rotors for lube or cooling, or both. I've read that somewhere. I've also seen injectors above AND below the rotors, with some strange percentage split.

Chase explain i was always under the impression that h beams r stronger even after lookin at companys ratings on them H beams are showing an average of 200hp over i-beams.
