I understand the 475HP is measured at the crank and I understand what higher altitude does to engine HP but you failed to mention the altitude effect would apply to both vehicles.

What I failed to do was to compare apples to apples. I ended up comparing Dynojet numbers to the non-Dynojet dyno used by ajag. My 5.7L Jeep feels nothing like my friend's stk. Jeep SRT and I'm closer to ajag's rwhp numbers than he is to a Jeep SRT. Hence, the reason for my questions.

An overlay of both dyno graphs on the same dyno would be the best way to compare or running them both on a 1/4mile drag strip.

Thanks

Re: Thinking about an SuperCharger...

I'm not a tuner and in no way do I claim to be one ..I just pay the guys who know how to tune these things to do so

That's all I know is that if I hadn't run out of fuel up top we could have dialed in even more timing to get more power

The best we could get was 420awd hp before going any further

After fixing the fuel delivery issue I'm sure we could have squeezed out more hp

As far as comparing to an srt..even when I was at 320awd hp ..you figure a stock srt is only ~360-370 and runs a 0-60 of 4.3-4.5

Not far off my 0-60 of 4.6...so once again I ask Michael ..have you tested real world 0-60 performance? Independent of dyno numbers?

Like I said..you're welcome to come join me when this gets tuned on the custom engine ..ill make sure to video the dyno runs

Re: Thinking about an SuperCharger...

By the way..I'm hoping to see a 475-500awd hp number come from my new engine setup on 13-14lbs of boost

I'm crossing my fingers ...anything less than 450hp and I'm going to be really disappointed

But who knows what'll happen..

Re: Thinking about an SuperCharger...

Again for the last time, I don't doubt what you're saying. I'm just looking for answers/data to make me understand. I don't claim to be a tuner yet I tune my Mustang with an Engine Management System(EMS) that is Mass Air based.

I'm not 100% familiar with the different accessories to the JGC. I have a Diablo InTune handheld with (3) Diablo tunes, plus (2) HemiFever tunes on the same Intune and I plan on testing them both at the New England Dragway real soon. I already tested them on the dyno and the Diablo 91 octane tune was better in terms of area underneath the curve and peak rwhp and rwtq numbers than the 93 octane Hemifever tunes. I was waiting until I ran them on the dragstrip before posting my results. Because of my engineering background I craze data. BTW, do you have your dyno sheets? And can you post them?

So to answer your question, no I haven't tested 0-60mph because I don't know what I need to get 0-60mph numbers? Personally, I like the dyno for tuning and racing for results validation. Heck, your old Jeep was probably faster than my Mustang 0-60MPH and I'm not joking.............lots of timing pulled to gain traction for the street.

Thanks
Michael Plummer

I use an ultra gauge with performance timers to test my 0-60 plus I have a track 15 mins from me. Might be worth spending the 85$ on an ultra gauge

Not to shabby on a all bolt on, no tune 3.7 lol.

Re: Thinking about an SuperCharger...

How accurate is ultra gauge and how many samples does it take in a second. Honestly, you should go to the dragstrip and verify your times for 1/8th and 1/4 mile you're getting with Ultra gauge vs. the clocks at the track. Some of those devices may not be as accurate as you think unless you do a comparison.

Thanks

It's within a tenth. And the refresh rate on it is matched with the can bus system so it reads as fast as the pcm does

I've taken up enough space, returning this back to the OPs topic. I'll PM you.

I don't have any experience with RIPP Supercharger but they have HP data which gives you an idea on what type of power you'll be making (IMPORTANT). You have a couple of drivability reviews but you should always take that information with a grain of salt. It's best to couple those reviews with a Google search for good and bad reviews because they're out there. Remember, I said not all vehicles are the same, so some of those issues could be related to the condition of the vehicle and some not......do your research. The larger sample size of information you get, the better.

If you contact RIPP, I'm sure they'll tell you how much time and effort goes/went into their drivability tune and I believe they have done their do diligence This is important and should give you peace of mind.

Good luck
Michael Plummer

RIPP Superchargers is a splendid one to behold
Re: Thinking about an SuperCharger...

We develop our systems for a "global safe" for all premium fuels, even with the regional differences with formulations. To get the most out of our systems, it is best to have a custom tune done to account for your vehicles specific mods.

Re: Thinking about an SuperCharger...

So just to chime in with a couple of questions - I have a 2016 5.7l and have been eagerly waiting for some updates on SC options...

I know Procharger makes a kit today, but has RIPP made any progress on the '15/'16 ECU tune?

Does anyone have any experience with the Procharger kit on a 5.7l WK2?

Thanks in advance for any info!

Re: Thinking about an SuperCharger...

Im also quite interested in everyones opinion on the Procharger kit. I've heard they will give more power than a RIPP kit on a 5.7L
