upgrade question

[Sawbones]

The Diesel Dynamics website allows you to configure the upgrades required to achieve a desired horsepower increase.



For 335hp, they suggest: stage 1 injectors ($800), guages ($320), and the boost module ($300)- total $1420.



For 350hp, TTPM ($549) and guages ($320) for a total of $869.



Is there another hidden cost factor in the 350hp scenario that I'm missing?

 

[KLockliear]

Nope, that's right. 335hp with Stage 1 injectors (50hp over stock). 350hp with the TTPM box (65hp over stock). Two different ways to achieve power gains.

Am I missing something here, how do you get 335 Hp out of a 50 HP injector. How do you get 350 HP out of a 60 Hp fueling box.



245 + 65 = 310

245 + 50 = 295



235 + 65 = 300

235 + 50 = 285



and all the above numbers would be BHP which is higher in numbers than RWHP.



The actual rear wheel HP would be much lower.



Please explain where I am going wrong.

Sometimes it's hard to say what each mod or combination of such will do to a truck until you finally put it on the dyno. I have an old 97 12v, which was "180HP" when delivered stock with an automatic. I put in the 215 injectors, and the "230HP" #8 TST kit, and later the gov. spring kit, (no HP increase, just revs further) and it dyno'd 300HP at the wheels, w/700 torque. That translates to approx 350-360 HP at the flywheel.

He's talking about the '03 HO truck w/6-speed. Ours dynoed 282hp at the wheels. Add 50hp, it around 335hp with Stage 1's and around 350hp with the TTPM box.

 

[Sawbones]

Sorry I wasn't clear, those are the dyno numbers for the HO 6 speed.



So, with the TTPM you get 15 extra ponies for $551 less than the injector and the boost module combination.



Sounds like an easy decision. Is there any reason to opt for the lesser hp set up?

 

[Sixpack]

$800 for stage 1's?:--)

 

[KLockliear]

James, no reason unless you want something totally stealth (can't tell a difference on the injectors other than power).



Sixpack, $800 for 1's, $950 for 2's and $1100 for 3's... all exchange. Get this, a new set from Dodge is $2600! Nothing like your '02.

 

[wsmalley]

Or my 12-valver..... $300 for six 370's

 

[Sawbones]

KLock, I can understand the stealthy-ness of the injectors. But what about the boost module that is required with them? Is this a plug in box? Is it easier to conceal or remove as compared to the TTPM?

 

[Sixpack]

Ouch!

Sure am glad I have an 02!

 

[KLockliear]

James, yes, it's a simple plug in and wastegate elbow.

 

[Sawbones]

Thanks, KLock.



Hope to be calling you soon, if I can ever get that new truck out of Mexico.
