You had EWP, Crank Scraper, Ram Air, and M6 with 26 pound clutch? If you have a graph I would love to see it and know what intake you used.

Had same cam, same heads, EWP was only worth $500 and 3whp NewEra Ram air, 6L80e with locked converter and their modded LS3 intake. Never got the graph from Ryan because I didn't care what the dyno read. Thats just always been me... They took the car to the track and very pleased with the results ET and MPH with a 5200 Circle D.

This is just for data for GPI and myself. They wanted to see the results of this package on my car. I already have 3 intakes for my LS3. We just have to figure out which will work best for my goal. I have a fast with long and mid length runners plus an LOD Speed works we have modified to fit a C6. Really looking to spin it 75-7600 if it is hanging on there to get me in the RPM range for the trap speeds I intend on achieving. I think it should make 480 torque on E85 pretty slick and carry it better as well.
The LOD intake is interesting. I've looked at the Sniper and TSP Billet/Sheetmetal one as well. But have a FAST Medium Runner for my 416. I'll see how it does. I feel like the torque loss before 6000 is probably too much on those really short runner deals, but they do carry after 6500 much better. The Medium Runner FAST is a good compromise I think if you want to spin to 7500. Beyond 7500 and the LOD or other sheetmetal type intakes are going to be better. And the LS3 architecture is really suited for high RPMs.

Anything the engine doesn't have to turn is helpful. ****, reducing the belt weight is helpful in that regard

Mine has electric power steering, I know what it was worth but on a pig gen I have to pull out crazy weight to break into the 9s. I had a jesel belt drive and was planning dry sump etc for a wild NA build that never got installed but things took a turn.

Thanks to Hiossilver & Darth_V8r for helping me get her back up and running. Step one is complete.
