Only wanting 650-700hp out of a 5.3? You clearly need twin 101mm's...lol.
This is the dumbest thread i've read in a long time. People really recomending 88mm's?

That's fine if that's your opinion, I've reached a very different conclusion through my testing on several cars on the dyno and the track.

How long are we gonna dance this dance?

You are the one saying my camshaft has a "problem". In another thread where someone posted nice results at the track you said "TU2 that's pretty funny". So again, while this is a camshaft I've used for years that has proven itself in extremely efficient combos you're on here saying it's a problem and don't expect a response from me?

The answer to your question is- As long as you keep posting nonsense.

Isky Iskenderian, who has designed cams for a long time says a single pattern cam will

"ALWAYS make more torque"

I have a single pattern cam thats close in spec to the tu2, and it is a monster from idle to redline. It is ridiculous how strong it pulls.

I just don't know what will work good or what will be a waste of money. It Is gonna be a drag car that might see a few miles of street but not a lot.. I wanna keep the turbo below 1200 ... what turbo would you use and why and will the tu1 work good or not? Any advise would be awesome
For a single, personally I would run a PT7175 and a TU1. Fast response and still 900rwhp capable. More than your goal but it will be super efficient at the 700hp level. Also, I would run different heads or mill the 243's and aim for at least 9.5-1 compression.

the tu2 will actually act a little smaller than my cam though, because the 112.5 lsa has the intake valve closing a little earlier, for a little more dynamic compression. it would work in a heart beat, but be prepared for the engine to rev.
LSA has nothing to do with when or where the intake valve closes nor does it affect dynamic compression.

LSA controls EVO, EVC and is a function of overlap. You're thinking of ICL as ICL controls where the intake valve closes and affects dynamic compression.
