VVT Cams
Im installing my PatG EPS custom grind today 
Not to get overly excited though I have a lot of work in front of me before I can stab the engine back in the car but still... Im pretty damn pleased to be making progress this project has dragggggggggged
I should be up and running by March and will update with numbers when Im done. Too bad PatG is or Geoff are just a wee bit far for me to travel for a tune

I see TSP lists three VVT cams on their site now, dubbed VVT-1, VVT-2 and VVT-3.

Very hard to compare to any other cams since they give no info on the specs. Maybe dyno results are available someplace?

I agree, very hard to compare.
In addition, I've seen reference to a TSP "VVT truck cam" in the mid-teens intake range and mid-high 20s exhaust range.
I went to mast and talked to the folks there and the impression that I got was that. If your not runnung their ecm, which I will not comment one where that actually comes from. They really made me feel like they didnt have time to give any support or time to what I was doing..... So I called matt at texas speed and purchased thier cam springs cam phase limiter and I am very pleased with the customer service and pricing. MAST was 250$ higher and said that they couldnt sell me the phase limiter because it was a comp product?? Like they are grinding thier own cams ??? Any way i'm not here to bash anyone just not happy about making a two hour drive to be turned away with the feeling that my checkbook doesnt work here. I will have this setup running in the next two weeks, dyno numbers will follow. By the way cam specs came with the cam, but I will not share them since the guys at mast helped me out and I will be doing more business with these people. I went with thier vvt-2 cam and I am building an ly-6. Hope to shed some light soon!!!
Yes, we finished it a week or so ago and we are VERY pleased with the results! I'm trying to get a write-up done on this one and will have it posted on the forums and our Facebook page very soon!

Found this thread for the VVT-3 in an L99: https://ls1tech.com/forums/gen-5-cam...er-80rwhp.html
Did I miss this? Would really like to see an update on VVT cams for LY6/L96...

The LY6 uses the same camshafts as the L99...the LY6 just has a bit better piston to valve clearance due to more exhaust valve relief.

First dyno pull Finally got this swap done and got to dyno it today.
397.66 hp and 392.24tq
This is on a dynojet dyno, L99 intake and fuel system. LY6 truck motor all stock with the vvt-2 texas speed cam. Cheap ebay forth gen camaro shorty headers and a 2.5 inch y pipe with a 3 inch cat back. t-56 tranny 3.42 gears.
Im happy with the results, It pulls very hard and is very streetable. Looking to get another 30 rwhp with hawks longtubes and full exhaust. Now need a rear end and 175 shot!!

L96 is just an iron 6.0L with LS3 heads and VVT, with about 9.5:1 static compression. All the other VVT cams fit physically and clear, but with the relatively low compression, you want to stay a bit more conservative on yours than you would with the L99.

Did you tune it yourself or have it tuned by someone else? Can you elaborate on what was involved?

The VVT-2 camshaft is a mid 220s intake duration camshaft that TSP offers for L99 customers looking for big power gains with good driveability on vehicles with aftermarket torque converters. The VVT-2 camshaft features approximately .620" lift thanks to the TSP VVT lobes.
Tune is a yes and no answer the cam phasing is done from texas speed the rest is done by a local shop that I am not happy with.........long story. I am about to load a tune frome texas speed with hopes of getting it really close to perfect. As far as piston to valve clearance I would have to say its fine. Ive missed a shift or two... and run into the 6500rpm limited and never had an issue. Not saying thats a good way to tell that ptv clearance is ok.. I do have the phase limiter installed. Im looking to go FI soon so Im really looking to see what the vvt can do with some boost!?! Im guessing that its really close to 500 fwhp with just a cam!!
