LS1 lid conversion: what lid to buy?

My cam only car used to fall on its face past a certain RPM with my old SLP CAI. After doing the lid i need to adjust my rev limiter because Ive been using that as my shift light now
I dont have before and after numbers at the dyno or track, but my butt dyno tells me 10rwhp is a VERY conservative estimate. I felt as much of a gain as i did when i put longtube headers on. The car was a whole different animal!

I completely disagree. The reason the lid offers a gain is because the 90 degree intake elbow on a traditional CAI is a proven restriction. Gains are 95% from eliminating that restriction and maybe 5% from any ramming effect you might get without a tunnel. You WILL see the gains on the dyno.

I'm sorry. I'm just going off things I read about how it worked for other people. I just finished mine a few days ago. It does feel like putting longtubes on again. It was a great gain and I still have a stock lid. I can't wait to order one this weekend. This was a ton of work to make everything fit right but knowing how long it took I would still do it again.

That's exactly what I want to hear. lol. I'm getting so impatient waiting for pay day. This is the first time ever that I can't find a lid used. I've had a post in the WTB section for a few weeks now with no luck.

I had the ugly moroso POS,swapped at the track to the SLP lid
Moroso to Lid w/stock Ls1 bellow and fram filter i picked up 1.8mph and 2tenths,will it change with ram air pan made and K&N most likely
SCREW the dyno testing of ramair/cai go to the track and get a slip!

That is a gain I can deal with. What was done to your car at the time?
I did forget to say that when I got my air box/rad support from the junk yard I only paid $10 for it because the corner was cracked and the guy let me have the K&N filter that was in it for free. I cleaned and oiled it and the thing looks brand new.

I'm happy with my SLP lid and K&N filter for sure. They seem to be pretty easy to find... I think I got mine for $60 with the filter about a year ago, they are definitely out there. I felt a night/day difference with this mod vs my moroso CAI, it took forever, but I feel it was definitely worth it. I would say a solid 10-20hp. Another thing to think about is how much air our engines actually suck through the filter. I read an interesting article somewhere that showed how much air the engine needs vs what it actually gets and those twisty turvey CAI's dont hold enough air inside them to give the engine what it needs. I also felt a giant improvement in throttle response. I think the shorter overall length of the air intake system is able to deliver a higher volume of air more efficiently. Long story short... SLP lid should work great for you, have fun!

I plan to use an SLP lid. Plus it has that cap on the drivers side of the lid that I plan to drill and use for an opti-spark.
Anyone need a K&N filter? I got one with my $60 air box off ebay and I already got one.
