Well, I decided that I wanted to do atleast one of my mods that I had laying around, before I go to the track tomorrow. So, I finally bit the bullet, and decided on the LS1 lid conversion. I used an MTI carbon fiber lid, with a K&N filter. Here's a couple quick pics I took yesterday morning of it. I'm not 100% done with it though. I want to make a radiator cover for it, to help keep some of the engine bay heat away from the filter. Also, I know the engine bay's dirty, but I'm going to do a lot of work cleaning it up after this week, and have it good and clean for Spring.



Here's a picture of where you have to cut, so the stock hook will clear the lid. I still need to smooth out the edges of the cuts though.



I'll try and get some more pics up later this afternoon or tonight.

 

Ummmm what is holding the lid down firmly onto the filter so that no dirt gets past it?

 

nice job just so peesp know where and what did you use for the rubber hoses to the throttle body and m.a.f

 

Can we get a few more pics man? I cant see where you cut, what is supporting the radiator, and what is being used as the lower air box for the lid. Looks great though!

 

So is there any real gain with this set up?

 

my gain was 2 tenths over the crappy moroso done at the track. that was also with a fram paper filter along with the stock Ls1 bellows.....

by far one of the fastest,benificial mod and cost wise,it cost me 50.00 and 15 min.

 

time at the drag strip isnt really a good way to measure gains because you could of just had a better run. Dyno proof would be better because i dont think there is 2 tenths gain with that lid over a CAI.

 

Hmmm can we clean up that bay a little bit please !!! LOL

 

Exactly...to much comes into play at the track. I wanna see some dyno numbers with the different set ups. Anyone?

 

You get those 1.7's on there yet? what time you going to the track tomorrow? might stop out...

 

well i will tell ya this,if your car ran consistant #'s and you changed something and now your car runs differently you would then suspect the mod you did is what caused it,correct?
i could give two ***** about what a dyno says,dynos do not give time slips!
infact there are a few people that have had the same results look up "the merv"......

 

Looking to do this to mine too...what is holding the lid down? I had mine mocked up and was trying to figure it out

 

I think what he's getting at is there's a lot that comes into play at the track. Not doubting you noticed a change but in the end the BIG question is, does going with this style of CAI give gains that are worth while to do the swap?

 

I've seen the radiator supports for LS1 cars go cheap. You might be able to swap to one of those.

 

^^That won't fit..

With it I picked up about .2 easily, and 2 mph. It just flows better.

Here is pics of mine, I used Stainless Steel to hold it down and to keep the Radiator forward. I cut into the Core Support also.

A little before and after for you guys so you can see how it is setup..

 

I'm about to do this swap on mine, I plan on doing a back to back test, same day at the track with the ls1 lid and a moroso cold air kit.I will have a ws6 filter holder and a fast toys lid.Try to pick up a tenth or so and get the heavy *** car in the 6's.

 

For the amount of posts and threads on this topic it really makes me wonder how anyone can attempt to disprove the gains!
i guess the calculated version of the ws6 ram air was just a reason an engineer at GM came up with to justify his/her job!

 

The gains, IMHO, could easily be 2 tenths. In fact, I'm going to do that mod next, but need to find someone who has done it cleanly. No offense to anyone's ride here, but I want a factory look while retaining my SS hood.

 

i like the ls1 lid set up

 

I have no doubt in my mind that mod or a LT1 WS6 intake is better than a CAI. Way to much plumbing on a CAI and the filter is in a poor spot. IMO
