Dual catalytic converter array

A couple of underhood shots showing the GT66BB turbo, skeletonized rad support after powdercoating, aluminum IC pipe with HKS racing BOV, and modified stock IC.

really nice work.

I think that stock IC may be your only weak link.

 

[atc82]

why the dual cat converter? just curious.

What kinda rad is this? It seems to be that's my favourite question nowadays... :-?

Why the dual cat converter?

I definitely wanted to run with a converter, and we couldn't find a single that would flow enough. The truck will be street legal and run on pump gas.

I think that stock IC may be your only weak link.

It's been opened up quite a bit - we'll have to see how well it works. It may be necessary to upgrade to a custom unit.

What kinda rad is this?

It's a Griffen.

really nice work.

It'll look even better after coatings are applied and the new motor is installed.

Thanks. Is this the drop in replacement or a generic one? If the later, what part number?

*Not* a drop in - this is a rad only, no oil or tranny coolers built in. It's the one PEP uses on it's 700 HP Sprint Cars. I'll ask Dennis to measure it for the dimensions. It will not fit in a stock configuration - modification needed.

" The truck will be street legal and run on pump gas."

Street legal perhaps from a tail sniffer standpoint, but what about the visual inspection?

I think he lives in a more liberal state than we do.
I pretty sure there are some states that still don't do a visual check.

DAMN C.A.R.B. :fist:

"Street legal perhaps from a tail sniffer standpoint, but what about the visual inspection?

I was under the impression that in 49 states, on a vehicle with over 50,000 miles, one could replace a cat (or in this case swap in 2 cats for 1) legally as long as it passes the other tests. So I wouldn't worry about a visual inspection - they will see 2 working cats. In Cali, I believe one would have to go to a "referee" station for emissions certification but again, if the emisisons are within legal limits I'd guess it would pass.

Is this not the case??

Uhh, I think the problem might be headers, maybe EGR (can't see it from photo)

Headers should not be a problem as long as emissions are OK. EGR - now if they make a visual inspection for that I'd have a problem...

Did you put a larger intake on the upper IC somehow... That looks 3" from the pics... If you did please share how it was done..

Thanks,

The laws vary from state to state, so you have to research what your state says.

IL - sniffer test, visual inspection for catalytic converter. That's it.

Newer vehicles, with OBDII can just be hooked up to a scanner to verify that they don't have any codes/malfunctions, and they are good to go. Wonder how that's gonna work out with guys who are reprogramming their OBDII stuff :wink:


I did call EPA up, I think it was an IL specific place, to ask about engine swaps. I talked to a guy that was supposed to be specifically knowledgeable about automotive emissions and whatnot, and he was useless. I had about 20 questions, and was hoping for some specific answers; mainly to guide me for my V8 engine swap in my jeep - he couldn't tell me a THING, the website didn't tell me a thing. I dunno where else to go for that info.

So hopefully your states have some better information available.

Yep, 3 inches - good eye. Just takes a little cutting and welding...

 

[mattw]

I was thinking about doing that but I was afraid that the heat from the welding may screw something up in the IC and cause it to leak... I guess thats not an issue..

A welder/fabricator familiar with these materials should have no problem. If done improperly, damage could result.
