What is a "stock appearing" factory charger?

Im talking work stock here of course.

I am running an HX40. The main part of the rules of the work stock class i may eventually pull a little in is "stock appearing, factory turbocharger from a 1 ton or smaller diesel truck".

I realize this is all about bending the rules. I dont want to be a "cheater" if i do pull, but its not like im going to have any real chance of winning at this point anyways.

Now, here comes the good part. Im sure there will be a lot of disagreement/discussion on the matter.

An HX40 is not a factory turbocharger on a 1 ton or smaller truck, But an HX35 is. The kicker is that you can take an HX35 and build it into an HX40 with a couple hours and some parts. A 60mm compressor housing/wheel from an HX40 will bolt right on, and is stock appearing. Then you can slide an HX40 exhaust wheel/shaft and a 16cm HX40 exhaust housing on your used to be HX35 and pretty much have a full fledged HX40 out of it. Everything is a bolt on to make an HX35 into an HX40. The whole turbo, even at this point is very stock appearing IMO. The only thing you can notice is the 4" exhaust outlet. Which could still be considered stock appearing IMO.

Lets hear what you pullers have to say about this... The thing is, it is still way behind a stock D-Max/ 6.4 powerstroke charger(s), but it will help the old 12v make some power. Enough to win for sure depending on the truck setup etc...

Would you guys say this is cheating, or just using the rules to their full potential?

I have all the parts/pieces excluding the turbo on my truck, to build myself an HX40 with a 60mm compressor, or an HX35 with a 60mm compressor. The HX40 would be my preference because of the 4" outlet/downpipe.

Stock appearing, or no?

thats like me I have a 62/65 14 on my truck and can pull work stock which surprised me and thats not all stock but I still get my arse handed to me
 
If I was the tec u would both be out of luck. It's not hard to see it's no longer a hx35.
 
if one were available, could a dmax run a different exhaust housing on their "stock appearing" charger and not get kicked out? I'd HIGHLY doubt it!


TO ME, "stock appearing" means NOTHING changes to the outside parts (compressor and exh. housing) just internal parts might be interchanged. That way, with a visual inspection, it looks stock.

So I say you're good to go in a class with "stock appearing" as long as you use put the HX40 parts in the HX35 and use the HX35 exh. housing instead of the HX40 exh. housing.

How do you figure? The cheetah's that the Dmax run ARE stock turbos with different wheels in them. The turbos you're talking are completely different turbos from stock. Not stock turbos with diff. wheels as in the cheetah.

So yeah, they are totally different in comparison as it pertains to the rule being talked about here.

doesnt the rule state 2.5 inducer and stock appearing so which is it because the stock turbo on my truck is tiny and theres no way I could compete in the 2.6 class with mine
 
Around here, it is supposed to be the stock appearing factory charger off of a 1 ton or smaller truck.

They wouldnt let us run any of the schwitzer turbo's or anything, which is fair enough, but when i can take my factory charger and build it into an HX40 with a few off the shelf parts, then Im not so sure that they could disqualify me for it.

Heck, some duramax's have a 64mm+ compressor wheel stock, and the stock CR turbo's are 60mm and 4in outlet so its not like it would be flowing gobs of air or anything.

I have thought about going back to an HX35 with a 60mm compressor, and putting an external wastegate on it to keep the exhaust flow up decent. Them seeing the external wastegate would be more likely to get my disqualified than a larger exhaust housing though, would be my bet. Just because it doesent look factory at all.

Mitch- The D-Max's are stuffing 70+mm wheels in their factory chargers and running them, so i dont know why they couldnt get by with an exhaust housing change too. Heck, you cant hardly see the exhaust housing on them anyways. Doesent mean the dodge's should have to not have one because the D-max's dont have any aftermarket housings available.

stock turbos with different wheels huh. makes sense.

This isn't worth arguing over. We could argue for weeks on end. Especially since I have a dodge and you have a dmax. Its just alot easier to improve the air flow on a dmax while LOOKING like a stock charger from the outside.


C-YA come-on, that makes you look like an A$$
 
A bone stock HX-40 got booted out of the "Stock apearing" turbo class last night. Why? its not like its a HUGE turbo and is going to whip up on anything else.


But with that being said, why not just get an HX-35 stuffed with HX50 internals????
 
Dont be mad at Mitch. He just gets into these technical debates, and he cant help but to try and take up for the D-Max.

He is really a pretty good guy, even if he does drive a duramax:hehe:

He isnt being a butt, he is just trying to provide a fair comparison.

At greentown? Who was it?
 
actually, I think there are some options for swapping out the exh. housing on a "stock" dmax charger, hence the question. It wasn't just a hypethetical but the point is, it's not legal IMO because it no longer appears stock. At least not how I read the rules and have had them explained to me.

As for the external waste gate, Eric, I don't see how there'd be any problem with that???


Just because it's easier for the Dmax to make air with a stock appearing charger doesn't mean rules should be different for DMax vs Cummins vs Ford. If you are gonna let there be different exh. housings on Dodge, then you have to allow the same for the DMax and Ford IMO.


TorqueT, about the "cya" thing. If you care to look at 95% of my posts, that's just what I type at the end. Not being an ass. ;)

You did say at least one thing important though. Stock LOOKING is what we're talking about, and yes, the Dmax (at least the 04.5+) can get lots of air out of a charger that LOOKS stock on the outside like the rules require.

Can you put a stock appearing super D-Max Cheetah charger on your cummins? If so, then no one should be able to complain about one charger or another, as long as everyone has equal opportunity to buy and use a certain charger.

Although I will admit, why would a Cummins owner spend big $$ on a D-Max Cheetah charger that will have to be custom fabbed to fit when you can buy a top of the line charger much less.
