This is Ryan from Xcalliber High Performance. And that's what we're working on today for Dragonali, our 2011 LML powered Sierra. One of the reasons they're so much fun to drive is the massive amount of torque you can extract from the engines, and their ability to shred tires at the drop of a hat, but one thing both of these trucks have in common is a built transmission since the massive amount of torque would destroy a stock trans. (LT)> We love high performance diesel trucks as much as the next guy, and we've built our fair share over the last few years. (Narrator)> Next performance upgrades for the Allison transmission. (LT)> Alright well let's get this thing unstrapped and move on to the next thing. (Austin)> Hey and additional horsepower, well I'll take that anywhere I can get. So why not put in a premium products when you change it out. Now on average you'd change your automatic transmission fluid every 60,000 to 100,000 miles.
(LT)> Yeah you know maintenance is all about helping your vehicle last a long time. (Austin)> And since you've got to do oil changes anyway for proper maintenance adding that FRThree reduces friction and it'll just increase the life of your motor in general. And then when you use the everyday diesel treatment product after that, well it'll maintain the lubricity in your fuel, which helps a diesel last a long time. Now that diesel extreme product that we put in the fuel tank, well that's gonna clean everything out because there's a lot of gunk that builds up in a diesel fuel system. Now obviously you're not gonna notice three percent more horsepower when you're driving around on the street but that's really not the reason you would do this. (LT)> And you know that averages out to a gain of three point three percent more horsepower than we started with. We started with an average of 435 and ended up with 449.5. Hey boy that is a nice, tight, consistent group if I must say so myself. (LT)> Really, dang! (Austin)> Two more pulls netted similar results, 450 and 449. (LT)> What did we get? (Austin)> 450 on the horse and 797 on the torque. (LT)> Alright well to keep things fair obviously same 20 percent load, same fifth gear run, same temperature and everything. Among the benefits are reduced fluid breakdown and longer drain intervals. (LT)> And finally we'll change out the transmission fluid with some of Hot Shot Secret Blue Diamond ATF.

Plus it adds a seven point bump in cetane improving throttle response while clearing up any black smoke. (Austin)> Diesel Extreme in the tank will clean out the entire fuel system, injection, injectors, lines, and even the tank itself. FRThree is added to the engine oil, which will improve fuel economy and horsepower with a gain of up to five percent. (LT)> Now we're going to add Hot Shot Secret to three primary systems on this truck. Identical pulls of 437 horse gave us a three pull average of 435. (Austin)> Yeah probably two or three more. Well let's do a couple more to back it up.
(LT)> I'll tell you what man, that thing sounds awesome. First thing we've got to do is get a baseline pull on this and see where we're at. It's got the LMM Duramax with some high performance upgrades that the average guy would do, and that includes the Banks cold air intake system, a fast lift pump, and high flow exhaust, down pipe, larger diameter, all the way to the rear, paired with some custom tuning. (Austin)> This is the 2008 Chevy Silverado 2500 HD. So we're gonna do some baseline testing on this truck, add a couple of additives and see what happens. Everything from cleaning out your fuel system and adding points to the cetane, improving fuel efficiency, and improving horsepower. Now we have an assortment of products here from Hot Shot Secret and they'll do many different things. Now there's a lot of different oils and additives on the market that advertise a lot of different things, specifically for diesel trucks. (LT)> With the truck safely strapped down to the dyno you might be wondering what they heck are we doing here in the first place. Today we're coming to you from our sister show Engine Power to take advantage of their chassis dyno. Plus see how routine maintenance can increase power and durability. (Narrator)> Throw all the power adders you want at your truck but without a built transmission you might be walking the track picking up parts.
