Default 500 hp what's it take to get there?

--------------------------------------------------------------------------------

Hey guys I'm new to this site and have a few questions about upgrading. I have a 2003 Dodge, 3500 4x4 with the HO engine and 6 speed NV5600. MY truck is a daily driver, pull a 30' travel trailer a couple times a year on vacation and I have a low boy trailer I use to pull my Polaris Ranger Crew and hunting stuff with. Oh yeh, light to light race every now and again

The truck has a Dr.Performance 120 hp box and 4" exhaust from turbo back. No other mods.
125,000 miles on the truck and I smoked the clutch the other day.

I would like to get rid of the Dr. Performance box. but get to 500 hp.

What Clutch would you recommend (I was thinking about going with a Valair single disc)?
I wanted to go with a SMARTY and add injectors, what size and make injectors do you recommend (if possible I'd like to increase milage a little). Will the rest of the drive train still be safe? Is all of this an unreasonable fairy tale?

Obviously you'll need the Smarty, but is 500 horses as far as you want to go?

First .... gauges. You're going to need to monitor the boost and EGT's with a 65% increase in power (305 to 500 is a 65% increase over stock).

If it is then 90hp sticks and a lift pump upgrade (FASS or AirDog) would be a starting point, and while you're at it you might as well improve the fuel filtration (add a F/W separator and at least a 5 micron filter). The 90hp sticks should be a good combo of fuel economy and power when used with the Smarty.

Since you're knocking on 500hp, look at a cold air intake and a mandrel bent exhaust. The 4 inch TBE might be okay but if you plan on more than 500hp consider the 5 inch TBE. And while you're under there, go ahead and do the boost bolt mod since the wastegate isn't electrically controlled.

The clutch .... you really need the dual disc, and consider upgrading the input shaft as well since you're increasing your power that much. The single is only rate to around 475hp, and since its a daily driver AND your tow rig, it's not going to do the job you need it to do. Otherwise you'll smoke the new clutch and/or bust the input shaft. I would look at South Bend and Valair's offering in the dual disc 650hp rated clutches.

Will the stock pump put up enough fuel to handle a SMARTY turned all the way up?

Does anyone make a set of gauges that will match the factory gauges on a 03 Dodge? I have Phantom gauges right now, but at night the entire gauge is back lit, not just the numbers as on the factory gauges.

Which makes the most reliable 90hp injectors?

Sorry for so many questions, but I want to do it right the first tiem and now have to do it again

I agree with alot of the other posts, however I only heard one person say you should upgrade the charger. I think you can get 500 quite easy with the smarty and a lift pump, (FASS or Air Dog) cold air intake and an Industrial injections fat shaft turbo, there is no need to change out the injectors, I make 700 hp in my 03 CR and I have 90 hp injectors and I wish I had the stock tips back I don't see why you couldnt make 500 without them and put that money into your new southbend clutch. By the way a dual disc clutch is not as drivable as the singles and if you aren't going to race with a load on then I would goto the single.

The New Valair Sprung Hub Nodular Dual Disc is an excellent Daily Driver Clutch. Smoother and better shifting than most singles.
