Re: Calling out Livernois,Demon & Ripps SC kit details

In our initial tests we put 8 SRT's on our in house Dynodynamic's dyno as control testing prior to launching. Conditions varied from winter to hot summer. These were tested NA and then boosted. We found the median AWD-NA power to be 355AWD WHP and the Median boosted AWD-HP 530. When we did clamp to RWD we found an 8% gain for those curious (but no one drives RWD so we're quoting AWD). Using simple math and trusting that the 392 produces 470HP crank as advertised by the manufacture, that puts us at a -/+ a 30% drive train loss in AWD. Our target was just under 700HP at the crank. 530AWD-HP + 30% = 689HP at the crank. This level of HP is considered safe and on point for the 392. We simply do no subscribe to the competitors logic that an engine will and must break if forced induction is applied. In our opinion, they are simply setting themselves up to fail and if engineered responsibly can and will last.

Our canned tune is set up with 530AWD HP as a target and that's what guys are reporting independently. If you guys want to gamble the pistons integrity add a few degree's of timing with a custom tune and you'll find more power, but that's on you. Below is a dyno with 1 more degree of timing. We've had it up to 5 and saw 589AWD-HP, but, again risking a chipped piston. There is no tuning magic, there is no defying the laws of physics and there is no smoke and mirrors it's just simple math. Our kits are designed for those of you looking to gain 200AWD hp and not sink $20k into your vehicles.

Based on our experience and 20years knowledge:
  • 500AWD super safe
  • 530AWD safe
  • 550AWD Yellow zone
  • 580AWD Red zone
  • 600AWD Won't last long

Please keep the 30%+ for crank HP in mind with these numbers.

Can you set it up at 580AWDHP (754CRANK) and daily drive it, yes, but no one will argue that it will not last. So be fair in judging what your are buying and getting yourselves into, might be more than you bargained for.

Added Note: If you decide to go for pistons and headers, yes you can light up the timing and find the 600AWD-HP (780crank)) mark on the V3si at 7-8psi with no pulley change. Vett's do it all the time so there is no under engineering of the compressor, it is a 1175cfc compressor and it will make 800crank providing the power-plants up to the task. We can get into a real conversation regarding moving up in compressor size and you as an individual can weight your options. We can make anything we want, we're not limited to any talent, engineering or market restraints. We reiterate that our current kit targets an easy to own 200WHP gain. Everything else from that point on is time and money.

Thank you for this! I come from a 4x4 background and have always heard 25-30% loss from trans AND transfer case. This was my dyno done last year...

Whats interesting is how rich the fuel is on the AFR... Temp was 61, Humidity 87%
Mods are Injen intake and Corsa catback.
These were people's replies to my numbers...

Forza is the Jeep Demon Performance is doing their Procharger setup on.

In most cases people don't believe the low number, that's why we really drive that number home in our posts. The data has to be true before we level the playing field. Since no one has engine Dyno'd the 392, no one knows if its a true 470crank HP. We use our values as a superficial calculation to demo the gain and loss as an industry standard. But take the crank power with a grain of salt. By that logic the highest drive train loss is 27% 470hp to 343hp and the lowest 21% 470hp to 380hp (only one car did this, dead of winter)

We're going by the 8 values we've retrieved on our dyno both NA/Boosted as reference, which varied from vehicle to vehicle for testing purposes. We've tested from 50deg inlet temps to a 92deg day with 90% humidity. Some values my be low and some high. Although two vehicles did hit the low number of 343-349whp heated up to temps. We don't glory pass our vehicles to get high numbers, we simply run them to temp and make a pass. We also have a smaller fan for the front to avoid false conditions and in some cases hot lap them to make sure they are clean even when conditions aren't ideal.

Stock HP:
  • 343-378AWD-HP
  • 390-410AWD-trq

RIPP Boosted:
  • 490-569AWD-hp
  • 510-550AWD-trq

With 530hp/510tq being our target to avoid damage to engine and drive-train - If we get slightly more aggressive with timing we can creep our way up to 550hp and 550trq or higher depending on risk tolerance. But we keep a keen eye on things like cat temp, inlet temps, knock and so on. So again, we feel the values are a blurry but fair assessment of expectations and feel we're working well within the engine and drive line's parameters.

Truthfully, I don't feel this type of drivetrain loss is accurate. We are an SAE certified Dyno facility, and have two dynojet dynos. We have never seen a 6.4 truck baseline below 370, and that makes sense because normally a 6.4 car makes around 395. There of course is some additional loss due to the AWD system, but I would say that you are closer to the 18% range vs the RWD's 12%

The days of 20%+ drivetrain loss are gone. No manufacturer can afford to have that much power lost through a driveline. Fuel economy standards are far too important these days.

My only mods are only a CAI and catback exhaust... I guess I can find another facility and dyno there but I have changed my exhaust since then. How/why would I have lower numbers compared to everyone else? Only 23k on my Jeep currently, probably 12k on the Jeep at the time of the dyno...

Mate dont be disheartened , as they say these things give a mass range of dyno numbers. there is alot of different dyno's out there and they will never all be the same or accurate . If your after true numbers i guess the track wont lie but even then you have reaction time lol
Here is my dyno sheet from ages back, i actually need to go put my system back on and see if the gthaus, xpipe and cats made any difference.

Re: Calling out Livernois,Demon & Ripps SC kit details

Even using the most conservative estimate of drive train loss, my RIPP supercharger has given me 600 HP. That's a great improvement over 470 HP, and I am quite pleased!
