What are approximate stock numbers for an '06 Hemi 4X4 at the wheels?

Next questions, I have a K&N Aircharger, Flowmaster Cat back with 50 series mufflers and a Superchips in high octane mode.

Would it be reasonable to say I'm over 300 horsepower?

Cheers

 

i've heard anywhere from 270-290 to the wheels on stock trucks so i would say you could very possibly be over 300 to the wheels

 

I would bet your modifications have added minimum HP. Maybe 5, maybe 0. I say run it on a dyno.

 

This really depends on how you have your truck setup. If you have it lifted with big mud tires on it and if in a quadcab you may be breaking even as far as rear wheel hp. Also your gear ratio and weight can affect it too. Need more info about the truck though to tell you more.

If you were completely stock with no added extras anywhere you are probably starting with 270rwhp.

+ Flowmaster exhaust 10hp = about a 5hp gain at the wheels
+ K&N Aircharger 15hp = about a 7 - 10hp gain at the wheels

Total with just those your looking at about 285wrhp and thats on the high end of everything. Now adding the programer which makes all of these plus your engine work alot more efficiently so you can add an additional 10-15+hp to the wheels. So all together your either sitting at or very close to 300rwhp however those are just rough estimates though and as many will tell you go down and have it dyno'd if you want an exact number. Also whatever you add look at the hp gains they claim. most will say "x" amount over stock or "x" percentage over stock, so dont just assume that once you add a CAI/Exhaust that claims to add 20hp that your getting all 20hp at the rear wheels. Again this is a rough guestimate so yes I could be wrong and you very well could be getting higher or lower gains.

 

Well, it's a 2006 Ram Quad Cab 4X4. 20 inch wheels, with stock gears (hell if I can remember the ratio, but I know they are steeper because of the wheels).

I checked on the Superchips and they told me it's worth about 20 horsepower at the wheels, but the biggest gain with the chip is this:

Under full throttle, the stock Ram only allows for 30% throttle position until 2800 RPM. The superchips eliminates that. They said it will certainly increase fuel mileage in town, driveability and greatly reduce 0-60 times.

However, I imagine Ill be shredding my tires off.

 

Yeah your probably sitting at 300+/- right now. I wouldnt trust the numbers Superchips gives you because its different for every truck/car as to what gains you'll get. They just give you the average as far as what they've tested and give you the higher number to sell the product. It is a great investment though so Im not doubting what they can do or claim they can do.

 

Bone stock you would be closer to pulling 260RWHP. If you pull much more than that check the calibration date on the DYNO ... because its off.

Mods do NOT add up by adding the claims together because they in most cases where the results of being the only mod on a stock truck. So while your intake may add 12RWHP to a stock truck and your exhast may add 15 RWHP to a stock truck together you would be lucky to get 20RWHP combined and not the 12+15=27 you got by adding the claims. So many factors change when you add a mod.

SPEED SAFE, AIR RAM

 

AirRam, I think you should sponsor some dyno runs on your products. It would be a great marketing tool to have dyno sheets to prove.

People talk about all these bolt ons but I have never seen real results on a dyno.

I have seen a lot of vehicles on dyno runs before and after exhaust systems. They maybe made 1 or 2 horsepower but usually it was closer to zero.

While in college I worked in a exhaust shop that had a deal with the shop next door which had a dyno. If you got a exhaust installed or built you would get a discount on dyno runs. It was really foolish how much money the shop owners made when the vehicle owners could get the same results (louder vehicle) by simply bolting on a loud muffler.

Once in a while we would put headers and a dual exaust on older Chevy pickups. That would gain you about 10 hp over stock. But the stock exhaust on those trucks was horrible, lots of bad bends, and that also included the removal of cats.
