I run a ported Boss intake and Steeda cai with a tune from AED. Compare to stock the Boss gives you a little bump way down low under 2000 rpm, a little less midrange around 4500 rpm, and a strong pull from 5500 to 7500 rpm. With 373 or steeper gears it's a lot of fun. Plus looks killer.

Does it give you a deeper intake sound? I grew up when cars use carbs, and one of my cars way back then had a twin Weber 45 setup. It sounded evil.

It sounds noticeably deeper and more free flowing. My wife even commented on the sound the first time she heard my combo and she thinks mods are pointless so for her to notice and comment about the sound was kinda funny.

I run it with my auto. It doesn't make more power up top but just carries it higher than the stock intake. It requires the correct supporting mods to be effective and the willingness to shift in the 7600+rpm range. Which with the manuals is tough due to the stock crappy clutch and corresponding parts.

Tom and Grabber...
In some reviews I've read, some are saying that the purge valve is no longer needed. They said that the inlet(green cap) in the Boss intake can now be plugged and the purge tube can now be taken off from the car. What did you do with yours?

I haven't dynoed my car but it does feel stronger above 5500 rpm and I shift at around 7400 with no problems on the man trans. My limiter is at 7600.
I kept my purge valve and installed it as described in the late model resto write up, check out their site not bama's.

WHOLE NEW CAR!
This intake manifold adds so much more potential to this coyote 5.0 v-8. The car has a entire new powercurve and just screams from 4000k -7000k RPMS...This mod along with the steeda cold air and tune are so complementing to each other. Easy install and worth every penny!

BOSS INTAKE AND STEEDA TUNE PACKAGE
Installs in about one hour and looks great. You will lose a little low end torque especially if you are used to the Steeda CAI and tune already on the car. The payoff is the high rpm horsepower you pick up after 5,000rpm. Im now shifting at 7,300rpm and the intake is VERY noticeable. The tune is really good too. A worthy mod especially for the money.

This is a follow up on the first review I wrote on the intake. When I wrote the first one I was running on the CAI tune because I couldn't load the 302 tune. I have solved that problem.
First let me say thank's to Gus for writing 4 or 5 tune's for this car untill we got it right. Being an automatic the tune is different then the standard . I really enjoyed working with him.
First the intake was the easiest I have ever done. I have been a mechanic for over 40 year's and have done intake's from the flathead to the hemi's.
The preformance improvement of this intake is hard to describe. I don't have a dyno so have to go by seat of the pant's in rating it. It will smoke the tire's for as long as you want to hold the pedel down. The mid band and low band performance is vastly improved and the top band will scare you.
I did not notice any torque loss which surprised me. I also didn't notice any gas mileage loss but havn't really drove it enough to tell yet.
I did my test run's on asphalt and it will kick the rear out quite a lot doing a WOT run's. On concrete it is undriveable as on the 3th to 4th upshift it get's compleatly sideway's and I believe if I keep my foot in it it would do a compleat 360. Not brave enough to try it myself. The car rev's to 7500 allmost instantly before it shift's,there is no lag to it anywhere in the power band that I noticed.
Every day driveability seem's to be as good as stock if not a little better.The intake and tune seemed to cure a lot of the little quirk's of the stock car as it come's from the factory. There used to be a 2 second lag when I floored it[ in stock trim ] before the car would downshift any where from 55 to 85 MPH. That is now gone.
Next I will have to word on some traction so I can go WOT on concrete.

Boss 302 intake?
I am looking into this also. I was looking at the late model restoration kit. Is impossible to use the gt intake tube if you want to keep your stock air box? Also, are there any emissions issues with this manifold in good old California?

Boss 302 intake?
I have had the Boss IM for a while now. The car pulls alot better, but I have other supporting mods as well.
I purchased the kit from LateModel and had a wire and OEM connect made for the purge valve to look OEM.
I had the Boss IM ported about a year ago.
On my set up, with a base tune and E85 I put down 420rwhp. This was my base tune for data logging the car. I have not been back to have it dynoed on the finished setup.

Love mine, the car should just come with it. NO torque loss down low with decent porting. Same drivability, same off idle characteristics, great throttle response still brake torques easily, etc... I'm currently 3.15/stock converter and the car IS faster in the 1/4 with it. Supporting mods are Accufab 84.5 TB, JLT intake, cat/reso deletes.
Added bonuses: It sounds mean (deeper), the car actually picked up 1-2 mpg, LOL....
4.10's going in this week so I assume things are only going to get much more bettah!

Lot's of internet "myths" floating around here that simply aren't true, re-parroted over and over again. At my altitude the car needs the gear (6k+ feet), everyone parrots the same junk about gearing as if one size fits all.... That's why I don't spend a whole lot of time here. The technical knowledge is not really up to par....
