The belt I got from autozone. Just took my belt and matched up one that was 1/2 inch shorter. The Lilly I had machines from a local performance shop.

Please let them know to contact us regarding the shift. We can help them out. Thank you in advance.

RIPP
Ripp makes a great product. I just like sprintex better there customer service is excellent and the horsepower that the stage 2 makes is crazy. Sprintex has a 3 year 36,000 mile warranty too. If installed at one of there dealer locations.

What about stock dyno graph on the same dyno? What percent increase in torque/power did you get? Different dynos, different dyno run procedures, etc., can all produce some wildly different absolute numbers, so it's the comparison to stock results on the same dyno with the same procedure that really matters.

I'm actually working on creating relative % gain comparison charts/data using data from each manufacturer's own before/after dyno charts. Here's a sneak peek at some of the results. I'll eventually write up a new post with a full explanation of where/how I obtained the data, how I processed it, additional analysis, etc.

Data source for Sprintex (note that stock baseline jumps around wildly at low RPMs a bit, which reduces confidence in the calculated gains at lower RPM): http://sprintexusa.com/wp-content/up...r3_6_12-14.pdf


Data source for Edelbrock (same compressor as Magnuson, so Magnuson can be expected to be fairly similar, but Magnuson has not released official before/after dyno results yet): http://www.edelbrock.com/automotive/.../dyno/1527.jpg


Data source for RIPP (still frame @ 3:16; stock data extrapolated up through the full RPM range based on making peak power at 6400 rpm have the same % loss from SAE crank numbers as the % loss in peak torque captured by RIPP): https://www.youtube.com/watch?v=1BU0eNis9w8

I suspect this will be a point of contention, so I will preemptively provide more details.

Here's the still frame from RIPP's video:

RIPP recorded a stock peak torque of about 240 ft-lbs. Compared to the SAE crank 260 ft-lbs, that's a -7.7% difference.

We know the stock Pentastar makes peak power at redline (6400 RPM). If RIPP would have disabled the stock speed limiter to record a full RPM range dyno chart of the stock engine, it is quite reasonable to assume that they would have also seen peak power at 6400 RPM, and that they would also see about a -7.7% difference in peak power from the SAE crank 285 hp. That would put RIPP's stock peak power at about 263 whp. There's a simple relationship between HP, TQ and RPM that allows us calculate that the corresponding torque for 263 hp @ 6400 rpm = 320 ft-lbs. I did a simple linear interpolation of the torque curve data from the last recorded point in RIPP's stock dyno results and the point at (6400 rpm, 320 ft-lbs). This linear interpolation actually err's in RIPP's favor as far as the calculated % gains, because the actual stock torque curve is likely more of a convex curve than a straight line, which would produce slightly higher stock torque/power in the middle of the interpolated range, producing smaller % gains in that range.

Here is a chart showing my copy of the RIPP before/after dyno chart data with the extrapolated stock torque/power curves. You can compare this to the original still frame above to confirm that I accurately reproduced the original data. You can also see that the extrapolated stock dyno data appears to be reasonable and in agreement with the general shape of the SAE torque/power curves at the crank.

I did not do a stock dyno run. Wish I had. I life's the jeep and changed the gears two days after I bought it

Well, not necessarily bone stock, but before installing the supercharger to get a valid before/after comparison with the only difference being the supercharger. Did you dyno before the supercharger, or only after?

Only after. I had the supercharger installed at jeep beach 2016. Only had the dyno run after install. I know that I can get a little more Hp out of the motor. Dyno run was done on a hot Florida day. I think I can get about 35 more rwhp.

Default Sprintex SPS incoming!

I ordered a sprintex sps supercharger for my 2016 JKU Rubicon Hard Rock. I'm running 3.5" AEV suspension with 35" BFG KO2s. Replacing clutch and rear drive shaft prophylactically haha. Also adding mishimoto radiator, fan and 180 degree thermostat as I am planning on moving to SoCal and wanna keep my baby cool. The SPS is supposed to be "Stage 2" although the regular Sprintex has an intercooler but the SPS has coated rotors as well as a 60mm Pulley so I'll be running 14-15psi. Also doing a boost gauge and wide band gauge. Really looking forward to see what this baby will do. Scheduled pre and post dynos so will post data when I have it. Anyone have good dynos for Edelbrock or Prodigy. Would like to see how this compares!

I'm running the stage 2 sprintex with the 60 mm pulley and a 1/2 smaller belt with full maganoflow rock crawler exhaust and the Diablo trinity 1000 also you must have a air\fuel gauge. I was pushing 10 psi but we upped the boost 15 psi on the stock motor and the jeep is a monster. And it is such a big difference from 10 psi I just installed Adams driveshafts and the rear is getting done as we speak your going to need Crome molly shafts. The last dyno it put down 411 rwhp at 10 psi can't wait to see what it does at 15 psi. I have an appointment next week but my buddy has an ls3 500 hp at the crank 2015 jeep jku and I pull on him like he is standing still. And I'm running a center force clutch
