This 800-Hp 351W build started by making it into a bigger, 408 Stroker. We then added a big cam, high flow @trickflowspecialties 11R heads and matching single-plane intake. With the @holleyperformance 950 XP carb and long tubes (they were too small) -the 408 just topped the 600-hp mark. We then added a 150 (or so) shot from a Zex nitrous setup. This resulted is an oh-so-close to 800-hp reading of 793 hp. The full vid has even more cool insight. Make sure to check@out @richardholdenerperformance

Oh, we’re making 900 hp! The key to success-don’t give up! This supercharged 4.6L 4V Cobra motor was a perfect example! After swapping in cams, an @fordracing FR500 (dual-runner) intake and @paxtonsuperchargersofficial supercharger, we quickly realized why cams and more rpm require different valve springs. With no springs and no blower pulleys at our disposal to help get us to the 900-hp mark, we employed the easy button (nitrous)! A quick 100-hp shot pushed our supercharged combo past 900 hp to

Thnx for 1M views on the original video where I used a 5.3L LS to drive and flow test the little AMR500 supercharger. Many were confused about this video, wondering why I didn’t use the little blower to boost the LS. The blower was only big enough to support 100-150 hp. It would be a restriction on the 440-hp V8. I just used the LS to drive the blower, then measured the flow and boost and drive losses. I also had this blower tested on an actual blower dyno in Sweden -same results! If you want re

The test everyone has been waiting for! Low Buck Truck cam on a 6.0L! Yes, we know it works on a 5.3L (Na and boosted), but does it also work on the larger 6.0L? What is your guess, knowing it works well on a 4.8L, 5.3L and with boost, is the 6.0L any different? The answer is obvious but the Full vid is up with all the dets! | Richard Holdener

Your mission, should you decide to accept it, is to choose a cam for an NA LS, a Nitrous LS, a Blower LS and a turbo LS! Is there any way the same cam works with all 4? Check out the latest video on my channel where I ran an @briantooleyracing Truck Norris cam on all 4 combos and (spoiler alert) they all worked great! Pick a cam that does what you want NA (idle, converter usage, power curve & rpm), then you can always add nitrous or boost later on! No need to change the cam! Speaking of cams-I h

Don’t Judge me…It Works! Even if it doesn’t, F*ck It…Buy a cam! I got two LS cams available for just $179 each that add big power! The Low Buck Truck works on NA , boosted, nitrous and carb combos with a stock converter. If you want more peak power, check out the bigger Truck Plus cam. Specs, hardness and dyno tested!

Don’t be scared! Can I gap now? Can I cam now? Can I go big on injectors now before I add boost? You can do all the prep stuff for boost and run your motor NA til you save up for one of our RHP Boosty Boys! The extra gap won’t hurt power ! With the right tune, larger injectors will idle and cruise and go WOT just like stock ones! You should always add a cam and springs (on Black Friday sale now) to any LS! Yea, yes you can mod now and add boost later! Check out the sale prices over @richardholde

The G42-1200 Turbo bringing the Thunder! Check out the latest video where I compared the infused with Quick Spool Technology (not a real thing) GTX3584RS to the big boy G42-1200. Not everyone cares about immediate boost-some of us want 4-digit power levels! (Life begins at 4 digits). Was there a power difference at 15 psi between the two (yes!)? Was there a difference in back pressure(again yes)? Full vid is up so pick the turbo you want for the power you want. Both are available at @richardhold

Looking for that mega responsive Turbo with Right-Now Boost (we call it Quick-Spool Technology) for your junkyard 4.8L or 5.3L LS (or other small displacement V8)? Get an @richardholdenerperformance RHiP800 (GTX3584RS-size) turbo with the 1.21 housing. If you want to run this turbo on a smaller 4-cyl (K-series Honda) or 6-cylinder (RB or 2J), get the tighter housing. On the larger V8s -we like the 1.21! This thing spools on the roll in!

Top 3 Reasons: Why the cam swap didn’t make the HP gains. Reason 3-Restrictions elsewhere. The more power your combo makes (with a cam swap) the greater the restrictions become. Things LS4 or LS1 intake manifolds, MAFs and air intakes. The same is true of stock exhaust manifolds, cats and cat backs. They were all designed for stock power levels and can hurt total gains offered by cam swaps! If you are looking for cams or boost or the fuel to go with them (our 1000-cc injectors are the best deal

Rating Turbos by HP! Rather than continuing to respond individually to all the Turbo “Experts”, this is just easier. Step 1. Choose your turbo (or turbos) base on desired HP output. 2. Choose Your turbo based on NA power output (determines pressure ratio required to reach desired hp). 3. Dial in things like response rate based on steps 1&2. HP is always first! That is all.
