I assume someone has built a stratus with a os91 hyper/pumped engine. The question I have is are you suppose to use the hyper carbon plate with the fuel tubing attachment vs. the OS plate that comes with the kit? Also if so, it dosent appear the holes are lining up with the Base plate that allow the bolts to go through the engine provided plate into the engine to lock it down. Suggestions/comments?

Is there a special base plate made yet for the os hyper pumped? If so anyone have the part #?

Thanks for the link...I found out I got the kit with the YS 91 8:18 ratio vs the OS 8:18 ratio, meaning base plate has incorrect holes drilled, from the instructions it sounded like it included both, but guess that isnt that case.

I think I posted to you on RR that i had a picture, it is posted here...the third picture from the left in this thread has a picture of how I re-attached the pump on the bottom of the engine mount.
