Before was 318RWHP/320RWTQ. Now it's 336RWHP, est. 335RWTQ. I don't think a MSD Blaster Coil will make that much of a difference..
This mod is something that will prove itself on the track more than it will a Dyno.

I feel sorry for you if you believe that a lid gained you 18rwhp over an aftermarket CAI...

Exactly.
That lid might be good for a couple more HP, but not that much.

Thats what you get from LongTubes. No way a box thats breathe's a little better is good for 18hp, or 18 more for that matter. Thats just insane.

Im not saying its not efficient and I think its a cool idea, but 20hp?
If you believe that, then your a fool.

Didn't say that. You tell me then where I gained better numbers...
I can tell you that the Lid will show it's gains at the track, I feel it on the street where it's different.

Didnt you just get done rebuilding your car? How would you know if its a drastic improvement?

I guarentee you could switch from a nice CAI to that Lid, and you wouldnt notice a damn thing, 5hp, maybe a couple more.
And thats giving it credit. Your motor/intake/tb only takes in so much air.
Unless you go FI, or cam, or whatever.

So you think that my fresh Engine, with everything all still tight inside of it is why
I got better numbers? I port-matched my Heads myself, I don't think that is what got it to those numbers..maybe all of the stuff together.

Yeah maybe.

Merv I like your car and what youve done, but lets not get off topic here.
Is the Lid a drastic improvement over a CAI? IMO, no.
Maybe a handful of HP, especially going down the road... but more than that?
I will need to see it to believe it.

I have the Z hood, and Im gonna hold off on changing my CAI to a box style. I will get everything done with my 383 and then im gonna see how much of a gain it brings. I hate having a hood that has intake capability, and not using it. I do not however think that it would be worth the money unless it brought something worthwhile .

Another benefit I can think of right away though is ease of intake removal. I get pissed when I have to remove the K&N CAI or want to service the filter. It gets ridiculous removing the plastic cladding underneath to get to it.

Merv, did you have to move the radiator back, or just cut the support??

Only problem I could think of is that since you have to tilt the radiator back more, it would not clear an aftermarket E-waterpump

Well I just want to throw in my two cents. I came from a Calloway honker CAI setup, which is probably one of the best. This intake was fantastic and to be totally honest I probably would have stayed with it had I not found a deal on the ultra Z hood. Now having had both I will tell you that its pretty close. In fact below 65mph there ain't much of a difference. The biggest difference between the two that I could tell was on the hwy. Mashing the gas and charging to 100mph happened much quicker IMO with the Ultra Z set up. Ram air is expensive, so the CAI set up wins that argument everytime.

I did my conversion about a week ago and I have to say the car is a bit different now. It pulls noticeably harder even at part throttle as well WOT. I have a Firehawk(obviously) and when comparing my ram air box to the LS1 lid, I have an aftermarket one but not sure which, it is alot better design. The main reason I did the swap was because I was tired of cleaning my filter everytime it rained or it got windy and threw a ton of dust and crap in it but I'm very pleased with it and won't be going back.

95Firehawk0158 when will you be able to provide a new E.T with your set-up? I'm thinking of getting an UltraZ hood and wondering if the gains are worth the swap.

Probably not until next month. Not having to worry about rain or dust was worth it alone. The slight gain was an extra.

I did a little bit of custom work..there is a little more to it than just a Lid. The Radiator had to be modified, some pieces of metal had to be added as well as making a Filter Box..

problem comes into play with copyrights. You couldn't just sell them, you'd have to be licensed and contact SLP, Whisper etc.... Takes a lot of work man. Now if your just making a few on the side and ebay them you'll probably be better off that way.

btw the lids do not have the bottom piece, and there harder than hell to find, cause all the LS1 guys keep them when they switch lids. You need the bottoms for the LT1 guys unless you have a junkyard at your finger tips that's a hard one.

Also unless you have a insider deal your probably just going to break even. The bellows alone are 60 bucks on summit, lids are 100 K&N I believe are 40 or so and then the ducting, there's darn near 300. For that price people could just go to Summit and buy it straight from a warehouse.
