I have the truck in my sig, and I am looking to get some nice christmas gifts to myself this year. I am aiming for the 350-400 horsepower range, and i was wondering what is the easiest way for me to get to that level. Whether i need injectors and a programmer, or if i am gonna need to go to a bigger turbo. Just wondering what you guys think...

 

350 won't be a problem with stock turbo....400 would be pushing it a bit, IMO.
Add a Smarty will get you to 350 HP. A nice set of Mach 1.6's would an a nice addition for an added 100 hp.
This combo would allow you to avoid tapping the pump wire; always a good idea with a 99.

You would need gauges and have to sometimes drive by the EGT's.... until you get a bigger turbo.
Even an HX-35 (opps, you already have one) would make a big difference.... but a 61/12 would be perfect!

I agree with RJ but just go with Mach 4 injectors and you can control the power, heat, boost, smoke with the Smarty. Get some spring clamps on those intercooler boots as well. Dont see a filter in you sig. A BHAF mod will work pretty good and 3/4 the cost of an aftermarket one. Napa part number 2790 for the BHAF. Then make your on heat shield. An Edge Juice would also work nicely.

 

With Mach 4s wouldn't the egts run way high with a HX-35?

 

I think with the quadzilla adrenaline or the edge juice with hot unlock will get you too 350rwhp alone. Throw a set of injectors in the mix and 400 would be there on full tilt of course.

 

Yes, if he stays on the throttle for a while.... but could be manageable for short runs, say 5-10 sec.
Remember it's not how hot you get....it's how long you stay hot!
In the red (egt gauge) for 8-10 sec does not hurt anything on the Cummins, IMO (and from my experience).

I'd probably use either a Edge Juice by itself or a TST stacked with a used edge ez and a set of mach 1.6s. That way you have the ability to turn down the fuel if needed for heavier towing with the HX35.

 

.... throw towing in the calculation and you're sure to melt things???
just trying to think of options along the same line. Thanks.

 

If all you ever want is between 350-400 hp a nice cheap but effective work combo/mileage is a set of rv275's and a fuel box

 

That will usually give you 300-325hp with that combo with the box set on kill.

 

Gauges
AFE stage 2
Exhaust
Edge EZ
RV275's

Thats an awesome combo and probably put you right where you want to be and the truck will be very reliable and egt's will not be an issue

 

Are you recommending a 35/40 hybrid?
How about the cracking people get in their turbine housings and heads?

 

Then they went too long......... or too far into the red!

Also have to remember that when running a Smarty box it usually lowers EGT's by 250-300*. So will running a larger exhaust by probably another 50-100*.

 

I dynoed 370 hp with an ez stacked with a banks ottomind with rv275's and now have only an adrenaline and feels stronger then that
