Anyone ever heard of these guys? Thier stuff looks pretty cool.

I just ordered one of thier fiberglass/resin carb hats for a holley carb. I measured (I sure hope I measured correctly!) and made a template and it looks like it should fit and clear teh pod. Not cheap at 60 bucks but its the only one I could find with a 3.5" inlet. I hope it works properly and is well constructed.

 

They look very nice. Depending on my intake choice, I was likely going to use one of them on my Turbo project.

 

I wanted to have a 3.5 in intake ducting dia. to match the MAF im going to use and theyre the only ones that carry one with the specs I need. Hopefully itll be as nice as it looks. At least its not made of plain old plastic so it wont melt if I have an intake backfire or something. The ones on ebay for the truck CAIs look like cheap sheet metal crap so I wasnt sure I wanted them.
After all, with a MAF it has to seal perfectly.

 

what are you doing with a MAF?

 

man that thing looks like it will hurt air flow. Insted of air coming from the front and sides it will now have to flow over and around the injector pod and regulator in a smaller inclosed space. Fine for a carb with no restritions on top, I don't know how well it will fly with a TBI. A junk yard grab of a caddy with a larger diamater around the injecter pod might be better and cheap too.

 

The dimenstions are 5 in wide/4in high with a 3.5 in inlet. I think it should be sufficient given that I have the smaller holley pod. With a standard one it might be a problem, though. I think the inlet on teh caddy one is too small. I want to use some of the ducting and crap I already have to make the installation smoother and cleaner. Really its teh only one that has all teh specs that I want while still being affordable. I wish it was wider around teh base but what can you do?

 

Im going to see how MAF works with tbi. I have an LT1/LS1 style truck maf, modified source code to use it, and a few other things but I still need a few more things to finish it off. I wonder if itll work better on a wetflow tbi then the SD does...

 

Very interesting, let us know how it works out!

 

Those look like they would be great for a cold air project. I hope that air flow isn't limited as mentioned above. It does look nice though. Looks much better than the caddy unit however.

 

that appears to be design procharger uses. PC comes in three diff heights. 2.00/2.75/3.75. i believe they are aluminum. i have serious clearance issues currently. the nut on AC top is barely touching the bottom of hood. the inj pod is just clearing the bottom of AC top. i am using a 3.00 inch drop AC with 1.00 inch spacer. this may work for cold air kit for me. thank you for finding this. i searched cold air for chevy and found C4/TPI. i need C4/TPI/TBI !!!!

 

Yeah it sure does look better than the caddy. the caddy has a oval hole about 2 3/4 by 4 just a hair smaller than a TPI tb inlet. You could use a hose off a camaro or caprice. I know it will not look cool but easy.

 

The caddy unit wouldnt be bad but I dont like the idea of having to splice lots of stuff like venturi fittings and tpi parts together in order to mate all the different dia. parts together. Although with out a doubt for a CAI the caddy unit would be cheaper and probably easier clearance wise.

That thing clear the hood at the tbi but it looks like its only at a 5 degree slant, which means itll stick straight out if its mounted facing forward. Ill mount it toward the master cylinder and use some bellows that I have to make a turn and mount the sensor and whatever filter element im using where the charcoal can used to be. I hope it all fits, although I suspect that jsut mounting it all up may be the hardest part of the project. Damn thirdgen hoods.

 

let us know how it works out

 

Got it in the mail today. Clearances are super close. Everything just barely clears. The hat just barely clears the pod and the hood just barely clears the hat. Another problem was since it was for a holley, they had a partition in it that seperatly directed air to the primaries and secondaries. Good for a carb, bad for tbi as the pod is in the way. I had to use a soldering gun and cutting tip to amputate. I can still smell the burning nylon plastic. Stuff smells so bad when it burns that I can taste it.

Another unforseen problem is that there was residual stress after it was molded so when the partitions where removed, each half bowed out, which made getting them back together somewhat interesting.

Anyway, heres a pic of the hat with some huge bellows that ill be using to round the bend and go off to the front. There ill have the maf and one of those k&n r&#236cer filters.

 

Another problem with having to mount it sideways is that the pod sits squarely between the intlet and the rearmost bore.

 

Looks like it has more room than I thought it would.

 

Would it be more benneficial if you could find something smoother to rout your air to the TB? I imagine the positive/negative gains wouldn't be TOO terribly noticable in our beefy 305's though, huh?

I thought of that... Once I get it all hooked up then maybe Ill search for a mandrel bent elbo or somehting to use instead.

As for size, theres what it looks like underneath with a stock pod for comparison. If it didnt have a baffle that had to be cut out, Id say it might be worthwile to use. With the baffle, though, one has to devalue the thing my chopping it apart to make it fit.

 

what about using it in conjunction with a tpi airbox like this?

 

I was thinking of that but the hat and the other junk thatll be hooked up with it looks like it may not clear the hood of its oriented facing forard. Ill have to take another look.
