Gonna buy one or the other, pro's or con's to one or the other?

Do they both come with the wider neck leading into the MAF sensor?

I dont want the skiny / narrow neck version.

 

I love my SLP

 

I like the TPIS one , looks alot better and looks that it will actualy works better :thumbs:

 

The TPIS gets it's hot air from under the hood. Looks cool....(3 filters are better then 1?)

The BPP Vortex is a Cold Air system that gets air forced in from in front of the radiator by the spoiler. The faster you go, the more air gets forced in! Looks good if you get the clear box to show the filter. It requires more work to install though.

Hope that helps! :thumbs:

 

:skep:

SLP, TPIS, and BPP all get air from the SAME location, or am I missing something???? The intakes are all mounted on top of the front of the radiator. See the picture above of SLP ^^^. And there have been tests, the 3 filter cones only have as much surface area as the huge rectangular filter in the boxes.

The only system that I've personally seen that looks like it has an advantage is the forced air system through the licence plate area, that's the only one pulling air from anywhere than under the hood.

There were also initially a LOT of complaints over quality of the BPP unit, all though I believe they fixed most of the issues, fitment was also an issue originally.

Don't expect a difference with any of them over the other, just cut your lid for free and buy a K&N filter, save yourself some money.

I have already cut the lid, I just dont like the skinny neck (restriction) that comes off of the MAF on the stock system.

What has to be better is the wider/bigger neck asseen here from the Mid America catalog.

I just installed the SLP version, and I can tell you it appears to get the cold air at a lower point on the car than the BPP and the TPIS. Not that this could make that much of a difference, open shroud is an open shroud, but the opening on the SLP which I enlargened scoops incoming air from just above the spoiler. Nearly the same idea as the forced air through the license plate CAI. I understand this incoming air may not really be forced and it is slowed by the convolution toward the rest of the intake, but it looks like a stock intake to those who don't know any better. :seeya

 

dohhhhh, I just realized the pic above does not show a MAF in it, so it is not for an 85..

anyone with a MAF...?

 

I heared that the Slp is the cheaper and better of the 3. Corkvette and Skidwnit are running the airforce-1. I have no idea who makes that one.

 

I would stay away from Breathless products.

Get either the SLP or TPiS CAI.

 

That SLP claw won't work on an 85 with vertical radiator. Anything that draws air from the engine bay is NOT a cold air induction.

 

I had the cut lid on my LT1. 2 weeks ago, I replaced it with the Breathless Air Rammer. There was a difference in fuel economy off the bat. Unlike the SLP Claw and a cut lid, the Air Rammer gets its air from outside. Part of the installation is cutting a hole in the radiator shroud. The lid has foam around the lip to "seal" the air box to allow only air from the outside to enter. The cut lid and Claw grab air from under the hood. This doesn't do much good, since you are pulling in warm air (or hot air if you are in a warm climate, like Florida). I also installed the IAT (Idle Air Temp) sensor to the base of the Air Rammer (costs $30 in any of the Corvette Catalogs). This way, the engine is told what the temp is where the air is entering the filter housing. Does it raise hp? No idea. I have never had it on a dyno. A member of the local Corvette Club in WPB, FL did a dyno run before and after installing the Air Rammer and showed an increase of 17 hp. He showed me the paperwork. As for the temp conditions outside between each run, I don't know what they were. Did it improve anything? Yes, my fuel economy has increased around 2 mpg on the highway and city. For me, that is a big thing, since I drive 70 miles a day in my Vette. If you are trying to decide about the Claw or the cut lid, do the cut lid and save the money. The Claw just looks nicer. If you are trying to decide between the Claw and the Air Rammer, I would go with the Air Rammer. That is my $0.02. :cheers:

 

:iagree: My thoughts exactly, NONE OF THESE UNITS are "cold air" intake and the BPP isn't some special thing, it gets air from the same place as the other units, look how close it is to the engine as well. There's not magically coldER air because you cut a little hole. I wish they had units like the Moroso I put on my Trans Am, the filter was below the frame even, huge cone filter. The only thing between it and the outside was a plastic panel that goes underneath by the little front spoiler, and I took that off, put your hand under the car and feel it sucking. It was completely sealed off from the engine bay. :cheers:


'85- sorry, was unaware you had done that, two-steps ahead of me haha

 

Sorry bowtie, but the SLP comes the closest to being true "cold air". The opening is just above the spoiler, totally out of the engine bay altogether. It is also 7-8 inches away from the hole in the shroud - it gets the "coldest" (actually least dense) air of all of them. :seeya

 

So the SLP Claw requires you to cut a hole in the shroud as well? Looks like it bolts to the same location as the factory air cleaner and is pulling in the same warm air a cut lid would bring in.
As for the coldest air, I think the Breathless Vortex gets that. It is sealed off from the engine compartment. It brings in air from in front of the radiator (similar to what BowTie was talking about with his TransAm.). The "small hole" is the size of the box they have the filter in. I think the small hole I cut in my shroud was around 9"x12". The air filter is getting the same cold air as the condensor, as the hole is located just in front of the condensor (making it a little colder than the air passing through the radiator, since the condensor does let off some heat as air passes through it). In my opinion, the Breathless unit is the closest to a cold air intake currently made for our beloved C4's.

I'm curious as well as I have seen many claw intakes in person and never a cut shroud with it.

 

Look at the picture above^^^^!!!! Odd, it's in the same place as my free open-lid mod :lolg:

If there is ONE that gets SLIGHTLY colder air it's the BPP merely because of the possible "shield" it has to the heat of the engine bay. The SLP is just cool looking, but if I was buying one that IS the one I'd get.

I'm with scorp and the guy above, show us how it gets colder air than an open-lid :rolleyes:

The BPP one doesn't have a "little hole" - it's actually quite large and is open to the elements. If you stick your hand up underneath the car where the radiator is you can touch the air filter. I don't know if it works better than any of the others but mine warped and isn't exactly top notch quality. Also, the clear lidded one's get pretty dusty.

 

Whitvette, I think jmrl98 has it backwards.

I had to cut an aprox. 1' + 1' hole in the rad. shroud to put the box in. The filter is actually goes 1/2 way through the hole.

As the air gets diverted up into the rad by the spoiler, it is under pressure and is forced into the filter.

The only other true "cold air" induction, is the one through the license plate, but it's opening is at a low pressure area. I think it looks ugly, but at the time it came out, it was the only one available. :thumbs:

 

Just my 2 cents, I have the SLP and there is no hole for magic HP to come in from. I installed it because I didn't like the look of the stock airbox. Untill I see some dyno numbers from the same motor, same day, and the only change is an airbox I will never believe you are going to see any diference, open air lid mod included. Perhaps if the car is a bit rich, then like the MAF mod then it might lean it out a bit but as far as 17 HP form one of these air boxes, no way. look at where the restriction is in the airflow its not in the airbox and none of these will get cold enough air to make a lick of diference.
If you like the look of one box over the other then I say get that onea and be done with it.
