LY6 VVT and Boost Questions
Hey all, just curious as to what you all are doing with VVT in forced induction applications? Would probably want to just delete it if possible to save myself complication unless there is something I'm missing as a reason to keep it after going to forced induction? Debating on an LQ4 or an LY6 with about the same miles for the same price and I don't know any of the ins and outs of VVT or how it functions with induction. Any info is appreciated.
Thanks

First off, you know LQ4 does NOT VVT right? It's Gen III, none of which have that

Yeah my wording was bad. Was wondering if the VVT in the LY6 causes any complications with boost. Was wondering if it ends up just being simpler to stick to an LQ4. Even just trying to pick the right turbo for my application is making my head swim much less wondering how boost works with VVT and how to delete VVT if need be. So much information to learn.

There are kits to delete VVT, comprised of different front cover, timing sprocket, and cam, plus any small parts needed. Easy job. ECM tuning also required.

I deleted it on my ly6 either call Texas speed and tell them u need a vvt delete kit do u have dod also if so tell them and they will send u the whole kit easy as ****. But u can use ls7 lifters gen 4 front cover cam retainer etc. If u have spare parts laying around like I i did. If u aren't sure what to do call Texas speed they sell these kits every day

I figured a boost cam was more optimal but that's just an uninformed assumption on my part. Think the VVT could actually work?

I haven't seen many vvt cams have good reviews but maybe I'm not looking in the right place. If i build a performance motor tho i can't see keeping vvt over a custom spec cam for intended purpose. It makes as much sense as people saying I want 700hp but I have to keep my stock converter and 7.5 rear end

Buy the ly6. Way better internals being gen 4. You could put a vvt cam in it(like I did) but your better off deleting it if going turbo. If your swapping cams anyway, I think the kit is around 200 or so . It will handle a lot more boost in stock form than an lq4.plus they come with ls3 heads from the factory.

VVT + Boost = VERT GREAT "spool"
Hi Grady, KEEP the VVT for boosted engines.
VVT cams are small as are turbo cams.
I have done many "boosted" VVT engines.
The turbo "spool" will be much faster with the VVT.
My help is free, just call 949-250-1797.

That makes sense to me. I mean, I'm not shooting for any huge huge power. Between 6-700 is just fine by me. I want a fun, rip around t top summer car with street manners, not something that I struggle to control. In a more mild application like this, still think it needs to go away? I'm so unfamiliar with newer stuff like VVT that I was thinking simpler just to delete.

So it will be able to function efficiently with VVT and 8-14 lbs? Or make less boost but flow more cfm? Any changes in a/r ratio or other turbo sizing specs to consider with VVT? I'm already having a hard enough time picking the right turbo for my application haha.

Keeping VVT in any situation is good, if you have a tuner that can work with it.
The more adjustability you have the finer you can tune the combo, VVT adds to the adjustability. The best part about it is being able to make power over a broader rpm range.
If I were you I would call Lance, can't beat free advice that is GOOD

VVT = Advance Cam ONLY
Hi 00 + Grady, FIRST 00SS, thanks for the kind words.
MY VVT method for a NON VVT equipped engine.
1. VVT front cover complete with actuator and connector.
2. MY Stand Alone VVT controller for a cost of $200.00.
3. Avon Gear timing chain AND lower sprocket.
4. My method to increase the strength of the chain guide.
5. My limiters placed INSIDE the VVT Motor.
6 The VVT Motor itself AND VVT cam core for Crower "regrinding".
7. The placement of a L-92 Oil pump.
8. The VVT single bolt cam fastener with flow valve.
9. Instructions sheet required for Valve Timing changes ALLOWED for VVT Cam ADVANCE ONLY.
10. Laptop GUI for VVT controller calibration and electrical connections sheet.
THUS any LS ( not dry sump) model engine can use a VVT motor. (1/2 Moon mod for 24xe made to CAS target for early use)
