If that is the case, then why aren't LS1 owners switching to an LT1 style CAI in droves?

Thats why I got them little hoses on the T/B. Really cool off that hot air


I lucked out cause I got the hood. I did it for cosmetic reasons. Don't need to nit pick for 5- 10 hp if any.




Looks great dude. Really nice work.

Yea, they did a damn good job, mirrors mine just about.

You run the N20..I'll just build a big Motor with a set of really good Heads so I can suck in more of that hot air..

So does the radiator MOVE out from under the filter on acceleration? A good test would be a datalog of the MAF and AIT with a CAI VS. this setup...don't you think?


And for the record, if you guys have never taken a LS1 apart, it has a plastic piece under the filter to block heat off the radiator and condenser.

When, in any Vehicle, does the Radiator move..
You are thinking about this too much..I picked up .2 in the Quarter goin to this. Another benefit is that it's a shorter Intake, less for the Air to travel, and it's straight to the Throttle Body.
I'll let you figure that one out..

Picked up .2? on the same day? You ran a CAI down the track, came to the pits and put the lid on and made another pass? Back to back? Same engine temp? Within say 1 hour? If you did not do these things, your .2 claim is worthless.

I am baffled as to why no one has either done the above or put a car on a chassis dyno and done the above.


OR a datalog, or even scan readings going down the road with the two swapped out. Write down the MAF and AIT reading on both.


I had a 5.0 LX, I had heard ALL these claims about how an electric fan was worth all this power and ET.....I went to the track, made 3 passes with the stock fan, logged them. removed it, put on the electric fan, made 3 passes....all on the same night, no other changes. The car ran the EXACT same 60ft, et and MPH.....that is the way you test something as this.

and the LS1 guys take that plastic out to do the FRA mod. the radiator is way behind the filter area. the AC condensor is the first thing thats near the filter and that doesnt get hot.

That is what I am trying to say, the LS1 has a plastic piece under the filter blocking the radiator heat. The condenser does get hot with the a/c on. But at the track with it off, you are correct. No heat of the condenser.


These guys are laying the filter RIGHT ON THE RADIATOR...say what you want, but that is NOT good.

And with using the ls1 shroud you didn't have to hack up your radiator support right??

To prove if there is a difference, i'll take my CAI to the track and swap them out and do a best of three runs. How would you like these runs? With DRs, without DRs, cut-out open, cut-out closed, Shifting at 6000 rpm or at 6300 rpm. You guys let me know what would make it easier for everyone. I can change alot of things just so we can get this over with, on the no gains, gains.

Your right about that. But it will not clear the stock hood or the SS hood. You will have to have a ram air hood like the ultra Z or a cal hood.

I'm planning on getting the harwood, Revelation said I might need to clearance a little on the underside of the hood to make it fit.

If anyone is using this with the 2.5" Harwood, please post up.

Yup, we are laying it right on the Radiator..

I got that special model too where the Radiator jumps, no **** it jumps , right out of the Hood, goes into the back, turns on the Flux Capacitor..and boy when you hit 88mph you better hold the **** on...



^^That's someone's new quote..

i went deeper than ive ever gone into anything to look for this. this is the topic WITH pictures on where you would need to cut for a lid on a 2.5" harwood cowl hood.

THE_MERV^^^^^^^^^^^^^
DId you HAPPEN to read this post?????????????? This is where I asked if the radiator moves out from under the filter when the car starts moving.


Think what you want rocket scientist, you ARE NOT duplicating what an LS1 has for a lid setup. go to Installuniversity.com and look at the pictures of the freemods to an LS1 lower airbox.


Until you PROVE the gains with a setup like in pictures in this post. And prove it like I stated in an earlier post, as far as I am concerned you wasted alot of time chopping up a perfectly good core support for nothing.

Again, here is how you prove me wrong:

Picked up .2? on the same day? You ran a CAI down the track, came to the pits and put the lid on and made another pass? Back to back? Same engine temp? Within say 1 hour? If you did not do these things, your .2 claim is worthless.

In case you have never SEEN a LS1 lower airbox...this car DOES NOT HAVE THE LOWER AIRBOX..DUHHHHHHHHHHHHH!!!???



An LS1 BLOCKS the radiator heat with the plastic LOWER part of the box, a STOCK LS1 lower box TOTALLY is sealed off from the radiator and condenser.

The LS1 "free ram air mod" cuts the bottom of the box out FORWARD of the radiator.


Does ANYONE do their OWN research anymore...or just jump on th"it must be better" bandwagon because everyone ELSE is??!! Jeez.


Streetwarrior96 Did it correctly.

I have a Suncoast hood and Ram Air setup on my Z28, other than Streetwarrior96's setup, IMO it is the only other way to do it.


You guys think what you want, until I see logged PROOF....I will believe it dont work.
