Default Any Blow Through guys in here?

Interested in going blow through with my 5.3 and s480. Looking to go with the msd 6010 and CSU carb and wanted to see who all up in here has went that route.

Please dont tell me to go EFI, im just looking for the people who have went blow through, not people who have had success in fuel injected.

Guys over at CSU advised me to run a wideband and gwt a holley jet kit to fine tune tye carb but they said they would be able to get it pretty close before sending it.

I run a Pro Systems 950cfm Blow thru on a 5.3 twin HX35's. yes you need a Wide Band and A jet kit if you are going with the CSU. I ran a CSU with the old 350 set up but was never happy with how it performed, but it was a good carb for the guy I sold it to.

I have a blowthrough 6.0 s480 combo. I run a CSU 750, I think Kevin is THE MAN! I did not need to mess with the carb at all on the engine dyno, but we did swap 2 jet sizes just to see, lol
you will definately need a wideband to see what is happening. If your local speed shops dont stock holley parts, then you may want to order a jet kit.
mine has only seen the engine dyno so far, as I'm still getting everything together in the car. it made stupid power 1067hp @ 6700, 911tq@5500, my driveline doesnt stand a chance, lol

Is your trans clutchless shiftable? If so how is it on the street, can you shift it clutchless WOT on the street? Can you drive it slow around town and shift with the clutch?

I just ordered my clutch assist GF5R, and it has not arrived yet, but it will act the same as the Doug Nash I have now: it 'can' be shifted clutch less , but you are supposed to stab the clutch pedal at least slightly to slip the clutch on shifts. It drives around town just like any trans, but it has no syncro's , so you have to rev match when driving nice.
Sorry for the thread hack.

Thats exactly what im running with LSA heads and s480 with race cover.

I think im going to give it a try with the CSU 750, looks like most guys are most successful with this carb
