Put an LFX intake manifold on your LLT... "The Adaptolator"... Coming soon? Discuss.

Since you can machine these spacers, ever thought about trying to design/machine a base that would allow a roots SC? Seems us LLT guys are out of luck with the other attempt at roots. Plus it sat way too high off the motor.

I hadn't thought about it... Perhaps down the road as the machinery I have at my disposal (Waterjet) isn't really suited for something that like... That being said, I am looking for a good machining place in the area to make these Adaptolators out of one piece. For early prototypes, I can cut one piece w/ the LFX ports on the top, and hand port the LLT ports on the head side.

Hoping I can find a place to just machine it all in one shot from LLT ports to LFX ports on the bottom.

The idea now, is that this piece will replace the aluminum LFX lower section, therefore reducing the cost of this mod as you wouldn't have to buy all 3 pieces (upper intake, lower intake, and Adaptolator). In the end this mod will be about $300 cheaper by not having to buy the lower intake portion.

Machining problem (almost) solved... I bought a CNC Mill today. Just have to figure out how to work it, and buy tooling

[Jason@JacFab]

I'm happy to report this project is still alive and kicking. KMPrenger has volunteered to test this LFX intake kit on his car. It will be slightly custom to fit his application (vararam cold air intake), so the lower LFX intake portion will have to be omitted for height reasons, and the adaptolator plate will be limited to 1/2" height instead of 1"... Not sure how it will fair out, but it will be interesting to hear his results and thoughts.

I am ordering the random GM parts today that he will need. I water jet cut a 1/2" thick adaptorlator plate yesterday from the popular phenolic material. I'll run it through the mill today. Once all the GM parts show up, I'll mail it all off to him. He should have everything in a couple weeks. Watch for more updates!

It is good to hear progress is still being made for the LLt motor.

We aren't sure what to expect...and in fact it may not change much of anything since I'm currently running a ported LLT manifold, versus the LFX manifold, which I think flows at a slightly greater rate than the stock LLT manifold. But it is an experiment and we will see what differences, if any, that I notice.

After that, I may try a thicker adapter, and go with a coupler for the Vararam with a slight bend so that I can run the VR intake with a thick adapter plate and see if I notice any low end gains, but that may not happen for a good while. First things first.

As for the ZL1 springs....I really like them a lot. My springs are from a basically new (very lightly used) 2012 ZL1....I think. lol. I was looking for just a small drop and I loved the way the ZL1 stance is, so that's why I went with them. If you want a lower drop, then you will want different springs. The ZL1 springs are progressive rate, meaning the rate increases as they compress.

I was super worried the ride would get harsh and that's the reason I never did drop springs before, but to my surprise I could barely tell any difference in ride quality versus the stock springs. Maybe just SLIGHTLY stiffer feeling, but barely. Now I wish I had done it sooner. The change in handling is immediately noticeable...it turns sharper with more confidence. The only other difference I'd say I feel is that when you hit a bouncy spot in the road I think there is a bit more "bounce" in the ride than before, but it is rare.

Swapping out the springs wasn't hard. I'd recommend it. You'll want to get an alignment after any spring swap.

Ok, I had though about switching to ZL1 springs when I installed the 1LE package on my car but i wasn't sure how the ride was going to be as the spring rates were tuned to go with the mag shocks. So I just went with SS springs which the 1LE pack calls for. All I want is a slightly lower ride, I don't like the super low stance you get with most lowering springs.

I'm in as well. I have a VR intake as well so add one to the list.

Any updates?

We had some delays and then I ran out time left to test this (I have other things I'm testing AND my wife and I just had our first baby) so I had to bow out of the testing for this one simply due to a lack of time to devote to this.

But its not dead as far as I know. I think Jason may do more testing locally.

Congratz on the baby!

Congrats! enjoy every second & take lots & lots of pics & don't stop taking them. They change so fast & grow up before you know it.

Congrats on the baby Kevin.
Curious where this is going as far as development. If I didn't already have a few other projects going I would volunteer for some testing.
