Keep VVT on L92 with LSA supercharger?
Keep VVT on L92 with LSA supercharger? I've been looking for more info on L92's that people have put LSA superchargers on and it seems to be split as far as what's been done between the various forums.
I'm not looking to build a HP/dyno queen, nor am I going to drag race it. I'm looking for a well rounded build with reliability and longevity being the goal. Originally, I was looking for a N/A build with low 500hp to the rears, but now I'm sure that's going to happen near automatically with this general combo.
Stay VVT with the L92 cam or upgrade? Loose the VVT and go LS9 or another cam? The bottom end of this L92 is mint, so it's going back together with new rings, bearings & etc. The heads themselves are fine too.
what do you guys have for thoughts/ideas?
thanks!

L-92 vvt Hi, I have done this with the L-92 engine KEEPING the VVT.
The camshaft was reground by Crower Cams to my SC specifications.
This was done almost ten years ago, my first VVT camshaft as there were no cores at that time.
I created VVT motor travel limiters that go inside the housing.
I replaced the Timing Chain AND increased the Spring on the chain idler.
I replaced the Valve Springs with PSI 1511 ML's.
I fitted FelPro 1041 Head Gaskets with Chinese studs.
The engine "benched" at 740 HP with 8 psi.
Would you like my help ?

My knowledge and researching of the L92 VVT only goes back just over a week, and the LSA supercharging of a L92 started a day after that lol!
I originally decided on 'just' a nice N/A LS3 swap a few months ago, but this combo came out of left field and now I have it, and don't want to narf this build up.
I found several threads on here and other sites that come close to what I'm wanting to do with these parts, but nothing that speaks directly to it and what I'm trying to learn.

I have another opinion. If it was naturally aspirated I would vote to keep the VVT. However with forced induction I do not see a need for it. You will already have a ton of torque down low. Keep it as simple as possible.

I am doing this... 2007 Yukon Denali 6.2L getting LSA blower in approx 2 weeks. No reason to delete VVT unless you want to crank boost WAY high and really need to run an 8 rib belt and then its requires to run a flat timing cover and LS3/LS9 cam.
New to me @ 150k miles. I am keeping VVT and tossing on a LSA blower. All parts should be here in the next week. I am also doing all new suspension as well from NorcalSS (BellTech 3" Drop Spindles Front & 2" +/- Adjustable Struts, Rear 4" Drop as well and the entire rear Spohn rear adjustable control arm package and adjustable pan hard bar)

Verdad Gallardo L-92 vvt Hi, I have EMPIRICAL DATA, this includes the REASON S/C and Turbo VVT works BETTER than VVT with a N/A engine.
My bench dyno tests confirm VVT works well with S/C engines,.
The S/C engine can produce 2x/3x the Torque, more, than a N/A engine.
Those who can't "spell", but can ADD, may be able to "see" the difference.
The chance to SAVE money when VVT, an OEM enigne, is used states the cost will be less.
The use of VVT will ALWAYS reduce the fuel used when calibrated correctly.
This is the REASON GM fitted VVT to MY 2007 Escalade.
