Looks really nice but does anyone have any dynoproven hp. I have a k&n cold air kit on my lt1 and I want to know if it is worth the hassel to change to a ls1 intake style system.
-Thanks

You cut a hole in your hood to mount an LS1 air intake with a stock, restrictive as hell, not to mention ugly, airlid?
Th whole LS1 air intake thing just looks better, I don't think it flows better than a nice 3" round LT1 cold air. My IATs are much higher since going with the LS1 air setup with the SLP lid. I certainly did not feel any HP gain, if anything, I lost HP. Most of the intake air passes in front of the hot radiator before getting to the air filter.
I will be going back to a LT1 CAI very soon. My old 9" K/N had alot more filter area to draw in air than the LS1 air filter too.
BTW- IMO-Thee best air intake for an LT1 is a factory WS6 air box setup that seals to a ram air hood. I used to run this setup and my IATs were never higher than the ambient temps, not to mention the ram air effect.

i ran a new best mph after i did the ls1 lid swap. it was only like a .50-.75 gain but still thats a gain. this was over the slp cold air. my iac didnt change one bit with it. once at wot it would only be a few degrees over the outside temp
but not worth the work/money

Verdad Gallardo Although it looks nice, I never thought the SLP cold air would be that great due to the twin tube design. With 2 pipes, there is more interior pipe wall than 1 large pipe. The more interior pipe wall, the more resistance.
You say you gained .50-.75? Thats a half a second or more, I would say thats alot. I don't believe you picked up close to a full second because of an air intake switch, unless you had the stock setup before.

As far as LT1 cold air intakes, a 3" pipe has more surface area than two 2" pipes.
I like what the_merv has done. The cut in the hood looks good and clean. I think the LS1 intake is better than the LT1 design, so it should make more power.

I dont have any dyno before and after for this setup on a LT1... I do have a stock LS1 lid vs. Aftermarket lid ON A LS1 comparison below. Stock LS1 lid has all these ridges and stuff inside it... the aftermarket lid brought up the HP and TQ about 10 points.
Hey Merv : Thank you for the photos. I'm not a fan of cutting the hood like that but, it definitely made it 100% clear that some sort of modification is needed to make it fit without cutting the hood up majorly.

I'm very interested in the LS1 intake on a LT1 using the stock & unmodified LS1 radiator shroud, and WITHOUT modifying whatever hood you have. Would you guys that have this setup working please make mention of what hoods your using? I have seen mention of the Ultra-Z working and possibly the VFN Sunoco hood but, are these just ideas or will these hoods work perfect for what I'm saying? Anybody? Anywhere? Bueller?....
