Hi guys,

I bought one and on the box it says it is a 75mm for 24# injectors but looks much bigger like a 90mm..so anyway, it is calibrated for CAI BUT it doesn't fit my Mac CAI. The housing on the end is much larger..Anyone else experience this? I guess it means I need ti get a Granatelli CAI too?:shrug:
 
O', my signature needs to be updated. It is a long story but brother's sent me the wrong pro-m in the right box. It said it was for 24# but they actually sent me the part for the 19# injectors. I told them I want my money back and ordered the granatelli from summit. Summit sent me the gramatelli and brothers re-sent the proper maf. I am sending the brother's back and keeping the granatelli.

PS does anyone know where to get those silicone hose covers so I can fit the two pipes together after I cut the flanges? Thanks.
 
If the pro-m (or whatever they are called now) fits use it and send back the gran. one?

Or to get the mac CAI to work go to the hardware store and get some fernco connectors that are the size you need (get one that is for the t-body end so they match while your there)...they are like 3-5$ at most. I made a home made CAI for like 20$ total with enough PVC to make 3-4 more (that I have done with the diff. n2o setups I am running, made one for each of the two diff. n2o nozzles I run for a quick swap set-up)
 
Well. I realized that after I bought the Granatelli that is configured for CAI, that the Pro-m was most likely not, the pro-m requires splicing into my oem MAF wires (me no likee that), and brothers Po'd me for screwing up my time table for putting the car together. The PVC is a great solution unless it catches fire. It gives off a poison gas from what I have heard.

Sometimes I get so upset at internet talk just like that!

I'm not talking just about Pokageek here but how things seem to be fact but when you search for those facts ...... they are nowhere to be found.

I have seen many peeps say they are concerned!
but then again
I have never seen any peeps say their home made cai caught on fire!

I have run different configurations of home made cai's made from PVC for years with not one problem.

The paint I have used on them has never even shown any kind of signs of heat for that matter.

I will say that I have heard pvc will give off toxic fumes if burned.

No sure why your upsettedness. If you have children, you will have a different set of goggles on I think. More on the safety side. That's the view I am coming from. I would rather someone know than now know.

I have a wife, children, and grand chlidren which I am kinda fond of. :D

The point here is it just don't get that hot under there. :shrug:

As for the fumes it may give off if burned .................

I would think the 6 to 10 inch section of pipe used is not enough to make trouble to the degree of a life threatning condition.

Where the toxic fumes thing most likely comes from is what I have always heard from being in the telcom business for all my life. Phone & Data Cable with a pvc jacket can give off toxic fumes if burned. In a lot of skyscrapers, you have a ceiling that makes the common area all that cable is in a part of the path that AC & Heat draws the air peeps breath. The concern is if you had a fire. The solution was to place the pvc jacketed cable in metal conduits or use a cable with a Teflon jacket.

For a little cai to cause a prob like above, you'd most likely have to stick your head on top of the burning pipe and purposely breath in the fumes.

My rant was about how you can see things being presented as fact and the same thing gets passed around over and over on the internet.

I think this is a good example of that making a mountain out of a mole hill thing and I was only using your post as an way to show what I was talking about.

If you think I was directing anything negative in your way or at you ........
that was not at all what I was trying to do.

If you think the pipe might melt or cause harm to you or any of your passengers, then I certainly do see your concerns for being cautious.

I don't know if I'd worry that much about the fumes from the PVC. There's a lot of stuff that will probably be on fire (if the cai was burning) along with the CAI that will be letting off a lot of bad fumes, i.e. plastic, rubber, paint, gas, oil, tranny fluid, coolant cooking off (maybe). Hopefully, once the thing was in flames that bad under the hood that a person would just get back (in the fresh air) and let it burn. Ouch, I don't even want to think about that! Good luck.

I dont understand that one, a Pro-M maf that is correct for your car should not require you to mess with the MAF wires. My Pro-M 80mm is plug and play and my old Pro-M 75mm was too. You shouldnt have to mess with the MAF plug or wires, you must have got the wrong one.
 
yeah def a lot of **** in a car that will cause toxic fumes. If you want to get real technical everything in a car will give off bad fumes. And like stated above if your cai is burning so is other stuff and by that time its working its way in if not all ready into your passenger compartment so you should be out of the car and a pretty good distance away. Just for the sake of knowing last car fire I was on (which i put out btw lol) was a Land Rover stock truck. Engine was toast and was starting in the pass compartment you could see flames coming out from under the dash. I got tired of wearing my scba mask and ripped it of after the fire was out but truck was still smoking pretty good and my throat burned for a couple days later. So a little piece of PVC pipe ain't gonna make things much worse

"Brothers" said that they changed em... The one guy that answered the phone,..well it was like I was bothering him and he didn't really sound like he gave a poop how I hooked it up. So, I gave up on them.

On the PVC, I think it is a very cost effective and creative solution and kinda cool but I was a bit concerned when it was said it would create poison fumes so I just didn't use it and was passing it on in a friendly way. I am not upset at anyone either.:)

Ever had a 1980's airbag pop on you? Talk about fumes! First of all it knocked my fries and coke outta my hand and all over my car and I literally could not breath, had to get out of the car and white faced like flour, lol.
 
When I took VRT they talked about people eatign and drining in cars and air bags blowing said if your holding a say a coffee mug it will slam into your face and really screw you up. They also talked about how people sit so close to the wheel and them blowing it could break your neck. I was like glad i'm tall and have to put seat all the way back to fit in everything i drive. Air bags are one of them things where yeah sometimes it helps but other times makes it worse. Like you said with the fumes and they can give you pretty bad brush burns. i was suprised when i was told that the thing that sets them off is like a shot gun shell so you know they got some kick
 
Yeah, it was a loud BANG. I was making a left turn and looking both ways and so was the other guy across the street at the gas station. That was back when I figured people would just look out for me if I pulled out. He thought the same thing and we both had just enough time to get out in traffic and hit the gas just at the right..or wrong time.
