What is a "stock appearing" factory charger?

Usually the rules say the turbos have to be specific to the engine make. Not always, but I think that's typically the case.

As far as that goes though, there's a couple of things that make that real hard. The way the charger mounts to the Dmax would be really hard to duplicate on a Cummins I'd imagine and the the DMax cheetah chargers are electronically controlled. Now, I know at some point (maybe all along???) the CR Cummins also has a vvt/vnt/vgt turbo as well. However, I'd think it'd take a pretty sharp cookie to figure out the electronics to get the DMax charger to work properly on a Cummins. It might be worth one's while to check around???

Surely something can be done to get bigger wheels in the stock Dodge and Ford housings isn't there? It's just that most just swap out for a new charger on the Dodge because it's just as easy and would be less money than a modded stocker.

However, on the Dmax, it's not as easy to swap chargers (need pedistals and different downpipes and all that jazz) on the DMax so it's a marketable item to modify the stocker on them. Plus it fits these rules so nicely. :D

Here in ISP it is "stock appearing, no larger than 2.6". Oxymoron right?LOL
 
Mitch, if you look at the compressor wheels on a stock D-Max charger, and a Cheetah charger, you can tell the difference, especially if you drag out the calipers. So are you saying that you couldnt run a cheetah charger either? It isnt stock appearing anymore than a 4in exhaust outlet is on my turbo. All you would have to do is pull the intake off and you can tell it is bigger in size.

And why cant the D-Max's run a different exhaust housing then? I dont think anyone would protest it myself.

If the rules said "stock charger", then i could see the HX40 being a no go. But since it says stock appearing charger, I would almost try it. It IS stock appearing in every way other than the exhaust outlet being scaled up a little.

Mitch, you are biased a little towards the D-Max in this case i know. You think its ok for a d-max to run a 70+mm charger in the stock appearing class, but I cant run an Exhaust housing with a 4 inch outlet???

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.

Fine, I say let them run a different exhaust housing. In fact, if there are options for different exhaust housings out there, Im willing to bet a lot of the d-max guys are running it in stock charger classes if they are of any gain. You cant act like the cummins guys are the only ones making the best of the rules.

at first i was worried about the whole stock appearing thing because i pull with three trucks running cheetah 68s and efi live and im not impressed ill say this my hx35 puts a beating on them every week and the tech guy pulls and owns a duramax and knows nothing about dodges so in our pulling association yours would pass but it does suck if they wont let you pull
 
you must be running some big injectors or a hotrod pump or something if you are beating up on Duramax's with EFI and cheetah's. Either that or they just don't have very good tuning or setups. Around my area (central Ohio) it is pretty much Duramax's cleaning up in the "workstock" classes most of which run EFI or PPE
 
i have 100 jammers on junk bodies, hotrod vp, and a quad boost fooler thats it wheel speed is 22mph truck is around prolly 430hp all three duramaxs are at 560hp
 
It's gotta be their setup or driving skills then if in fact they have that much more power than you. My boss has an 01 that he just p-pumped running twins in an s300-s400 setup. It runs good. Took a couple cracks to get the timing set. I am looking at building my turbo so I can keep up with the rest of the guys around here that have turbo work done. I will say one thing about the Duramax though it is real easy to get up to 500hp at the ground but much more than that and it is big dollars. Can't beat the cummins for the stout bottom end.
 
well i out pull a dodge 24v with a 62mm, 150s, adr and a dodge cr with a 62mm, smarty and nitrous. You can make a very strong running hx35 truck i havent even pushed mine yet been at this power for 20,000miles and no shaft play, egts 1575deg, and boost 38-40psi

But I hate this stock appearing rule the duramax guys go by around here let me stick a s366 on my truck against your cheetah 68 and see how close we are. But im not moving up cause you have to have a full fire suit and snell approved helmet come on this is my dd not a full on puller.
 
The reason the Duramax guys don't just throw bigger chargers on and pull the 2.6 classes is cuz that most likely means building the bottom end to be close to competitive and not blowing up. That is why they stick to the cheater turbos. Basically what it boils down to is if you aren't cheating you aren't trying. welcome to the world of brush pulling
 
Well i have debated putting a stock appearing hx35 on mine was told it would be 550-575 maybe a little more depending how hard i lean on it, but im not goin to spend that kind of money when i can by a much better reliable charger for cheaper and make alot more power.
 
If the cheetah turbos are a problem in the stock appearing turbo class why not put a max inducer size in the rules also.
 
around here I havent pulled much but I know most places the rules say 2.5 inducer or smaller which is why I run a 62/14 its not stock but on a 3rd gen being buried down in the back they look at it and say stock appearing looks good Ive never had trouble. It makes it fair IMO because its so hard to make a HX35 or HY35 like on my truck stock make good power. I would like to see all the rules be stock appearing meaning nothing to radical on exhaust housing and inducer side be plugged to keep everything even. Its not like with my little turbo Im going to wipe up the workstock class Im competitve but not yet won. If I was put in 2.6 it would be pointless. just my 2 cents

I think this would be a great idea, but i just think it would be hard to talk anyone else into it.

I think a stock turbo/2.4 class would be awesome. Anyone could run an aftermarket 2.4" turbocharger(which is 62mm), or you can run the stock one.

A lot(all?) of the duramax's are 65mm+ stock. So, they would still have a larger turbo, but for the other guys that arent that lucky, they could run an aftermarket 62mm or less charger. I think this would make it very competitive. A simple 2.4 plug would work on the aftermarket chargers, and the others you should be able to tell if they are a stock charger or not.


We are having a pull local that has a work stock class tomorrow night. Im pretty sure mine would pass tech if i did any good, and I am thinking hard about pulling at it.... At this point, I have a hard time thinking anyone could really give me enough information/proof to be valid in kicking me out of the class. My turbo doesent flow enough air to get excited about, especially since it only has a 58mm inducer, and if someone wants to disqualify a 12 valve with stock injectors that doesent even smoke going down the track, then so be it. I dont think it is cheating, but rather using the rules to my advantage.

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. ;) C-ya[/QUOTE]


Sorry bout that my bad. :doh:
 
Well, I did some reading, and the rules for tonights pull is supposed to be a stock, unmodified charger from a 1 ton or less truck, so i probably wont pull. This is a different set of rules than i was talking about earlier though, and it is only the rules for this particular fair's pull.

Anyways, since it says stock, unmodified, I think i will pass and just watch, but it does make me want to put my HX35 back on the truck so i can truly run work stock without any hassle.

Last weekend I pulled in a run what you brung class and pulled the same distance as the duramax that got 2nd tonight in work stock. I was also 1500lbs light. Made me think i might of been able to be in the money if i had of had a stock charger at full weight and pulled.

Eric
 
I pulled in frankfort fri and kind of bobbled and hit 3rd and went from 4200 to 1600 and lost all momentum and finished 8th in workstock but I pulled in a run what you brung class which had the white pro stock Dmax and a bunch of good running 2.8 trucks but I beat a couple of the trucks that beat me. I wish i would have pulled as good Fri as I did last night I would have won money
 
the way i see it is if you think you can get away with it......do it.....i mean come on a stock D-Max turbo can take you into the 500-550hp range....whereas the stroker turbo is good for like 400hp and cummins about the same.....so i dont think as many ppl running d-max's change the turbo as you think they just have an advantage from the start.....up here in NW Ohio guys that run and win in the street classes also pull in the stock classes ......now that i have a problem with....but who is to say what stock is.....a true stock pull should mean no injectors, tuning, turbo's....but you and i both know that they are runnin all of them......with my set up i shouldnt be able to pull in the stock class....but i would still get my ass handed to me....thats why i dont pull my stroker....i cant compete with a D-Max runnin efi live in a stock class.....

the rules to the last pull i went to is if they think you smoke too much you get DQ'd haha ok that makes no sence......
 
Stock appearing in almost all aspects of competition, means the externals must be stock. You can do whatever you want to the internals, from the exterior it looks stock. I would say it they didn't come with an HX40 style exhaust from the factory, then it isn't stock appearing.

If you are talking about my HX40, then how would you prove it to me that its not an HX35? It doesent say HX40 anywhere on it.

it must be a machined hx35 housing running a Hx35 ex housing. Then you can run it. The hx40 runs a larger comp housing and I can tell the diff right away.

Sry for any typos I am on a iPhone
