Hmmm... true.

Those are 79lb/hr injectors installed.
so you might as well say your gunna need 79lbs to work with this cause if its at 74% IDC then 60s are gunna be way high. So its safe to say 79lbs are going to be needed with this supercharger

Other runs I did take it to 8k but was recieving knock due to the cooler IAT2 and stupid me still had the IAT spark adder still enabled from the dyno runs. I figured most people using the 3.34" pulley will be stock engines and won't be running any higher than 7k anyway.

About a 1.3psi increase over the stock blower and 2.8" pulley if you do the math from that MAP value above. 15.3 stock blower vs 16.6 with the TVS.

About the same. I can't feel the 1-2psi difference.

Probably. No idea what the actual power to the wheels is yet. It could have higher or lower parasitic loss, the thermal efficiency difference, etc.

Yeah, from what you are telling me, it'll probably be out of the ballpark for most. I'm going to hate having to install a custom MAF housing and still haven't decided on the route I want to go with fuel yet.

Eh, bigger MAF housing would do the same, no guarantee if the LS2 MAF would give me the overhead needed.

I'm debating on return style or using a returnless electronic fuel pressure regulator with the supplemental pump I have.

raven ....ya its frequency will lower but thats only becuase its in a bigger pipe, the stock maf in a 85mm housing will give the same readings

witt i would go with a return style with a walbro in tank

Eh, its a pain in the ass to get the fuel sending unit to work with an aftermarket pump. I thought I found one or two that would be the stock height but I'm not 100% sure yet.
