Sorry I missed this post but wsnted to reply....
-Non pinned crank pulley concerns me
.... spinning the crank balancer is not an issue 8 lbs boost and under with our centrifugal supercharger, assuming the crank bolt is tightened to spec. At ~ 10 lbs it becomes an issue for sure. Roots style SCs are a different animal as the mass of the rotors are much greater.
-Would want to understand the supercharger operation/mechanicals better. Is it helical cut or straight?-nevermind, watched the youtube video, very interesting plenary setup.
.... The OEM-style superchargers we offer use a state-of-the-art fluid traction drive system to drive the impeller, rather than the traditional gear drive system. This allows the superchargers we offer to spin higher (impeller speeds up to 90,000 rpm vs. aftermarket units @ 60,000 rpm), along with virtually no noise or “gear whine” that is typical of other superchargers. This Traction Drive System transmits power through the friction created between its planetary rollers and a unique hydraulic fluid, rather than through a traditional gear drive. We use a unique traction fluid in the system that is designed to increase viscosity under high surface pressures. This fluid gives the rollers additional “grip” and prevents slippage of the smooth rollers by increasing the friction between the planetary rollers, while also cooling and protecting the system. This traction drive system combined with the latest technology in centrifugal compression provides greater efficiency and less noise. -Intercooler seems a bit small for the application
-The parts are all there, would be interesting to know what spark plugs and injectors were used
.... iridium tipped plugs, 1 step colder, and injectors are ~52 lbs at 58 psi
-Personally, I wouldn't buy or install this kit without having a local tuner, and I'd certainly have a boost and wideband gauge at a minimum to get it setup right and make sure you don't lean it out and blow a piston
.... the calibration provided is certified and validated (has an EO or EO pending) as long as you do not make ANY modifications. If you put on a cold air or other mods, you should have it re-calibrated by a reputable shop, but is no longer certified.
-Another concern; are they running on the stock fuel pump? I see a boost a pump located on the components page on the site, I'd probably at least want that if there's no fuel pump upgrade to make sure it can get enough fuel. - stock fuel pump is adequate for kit as provided.
Install Instruction Recap:
-Comes with one stage colder plugs, that's good and makes sense. Wonder what they are
......... noted above
-Interesting that they want to replace the intake manifold gasket, I've never heard of that failing? Haven't read about that on other kits at least, on my setup with 7-8 max PSI it hasn't been an issue.
.... it is poor practice and not recommended to reuse gaskets once removed. Gaskets are 'crushed' into place and typically do not rebound enough to re-crush to create a proper seal. Not replacing gaskets is a good way to create vacuum leaks and other problems.
Comes with new injectors, that's good. Wonder what they are.
...... 54 lb at 58 psi
-3 BAR map sensor, that's cool. A bit overkill but no big deal. Doesn't mention that the new sensor probably requires a bit of modification, had to shave some plastic on mine to get it to work, think it was built for the hellcat or a different setup
..... chosen for low cost, high availability. Whether it is a 2 bar, 2.5 bar, or 3 bar, as long as the sensor is properly calibrated for, it doesn't really matter.
-Delete shutters and disconnect, makes sense that you need room for an intercooler. Will be interesting to see if they hook anything back up or tune delete it so the CEL doesn't kick in
.... depends on vehicle. there is no CEL visible either way.
-Well, the supercharger mounting plates seem robust enough, although M10 bolts?
..... bolts and sizes vary depending on the kit. All bracket mounting and hardware is stress and deflection tested with FEA during the design process to minimize both.
-Huh, here's where I may have the first problem or question. This kit uses the existing crankshaft pulley, and it doesn't pin it in place. That would worry me, at 8 PSI I'd be worried about slipping the crank pulley, especially on a six rib belt and utilizing the existing belt tensioner? The site lists upgraded tensioners to replace stock but the replacement isn't covered in the instructions.
..... depends on the vehicle application. Whatever tensioner is used, it is adequate for the application with the provided serpentine belt. Not all serpentine belts are created equal and some stretch more or less based on load. Every kit designed is tested for supercharger pulley belt slip on the dyno.
-Separate SC oil cooler, that's interesting, I do like that the kit maintenance runs for 50k between oil changes
..... recommended maintenance on the traction oil is 2 years or 24k miles
-Wow, the intercooler seems a bit undersized? Not sure. I went with a much bigger one, at least it has an intercooler! The brackets are decent and at least are ready to go. Only two though? And self tapping screws for the right upper bracket? Looks like you'll get some support from semi-affixed intercooler tubing?
.....Our intercoolers are optimized for their respective applications. Intercooler size and design is not as straightforward as one would think. Bigger is not always better, and there are many factors that go into heat exchanger design and optimization for the application. Bell Intercoolers has a good FAQ.
-Speaking of intercooler tubing, is this a 2, 2.5 or 3" setup? Seems like the intercooler piping is pretty small (answered later, intercooler is a 2.5" setup)
....depends on application. Typically 2.5 to 3" tubing is adequate. Again, bigger is not always better here.
-Well, not a big fan of the clamps for intercooler piping, much better clamps out there than the hose clamps they're showing
.... depends on the application. We include stainless T-bolt clamps where necessary, and stainless worm drive clamps where it is not necessary. The tubes will not blow off if installed properly.
-I don't know the size of the blow off valve but it seems small to me? Don't know if it's the standard 50-ish MM mount but seems smaller
.... Depends on the application and how much airflow needs to be recirculated, but they are all at least 50mm.
-Finally a decent clamp for the throttle body at least!
.... again, clamp type depends on application, but Dodges typically have a tapered throttle body so much more clamping force is necessary.
-Guys, the new air intake sensor, can you stretch that cable any tighter? Looks like instead of using a new threaded sensor they just clamp the **** out of the stock sensor
.... you don't need a threaded sensor, it only adds cost and additional parts. You can manipulate the harness to make it not so tight.
-Comes with a tuned ECU from the company, that's interesting. Hoping/assuming they do follow up or mail tuning, which means you need to capture logs and if you don't have a diablo or something similar you can't upload the new tunes
..... You do not need to touch the calibration, the calibration provided is certified and validated (has an EO or EO pending) as long as you do not make ANY modifications. If you put on a cold air or other mods, you should have it re-calibrated by a reputable shop, but is no longer certified. This is true of ANY supercharger kit from any manufacturer.
-The oil filing procedure for the SC requires a vacuum pump?
.... no vacuum pump necessary, read the initial fill and bleed procedures. We originally were going to let people fill it either way, but it just added confusion.
-Clearenced is a new word. Got to 'clearance' the back of the grill so it fits because of the new intercooler - You need to make a spot for the intercooler tube to go
.... Modification of the plastic air deflectors is much better than just removing them completely. The vehicle's factory radiator is typically "sealed" to the front grille opening to maximize the high pressure zone in front of the radiator. Sure, we can just take out the plastic panels instead of eliminate them, but that would just hurt the cooling ability of the system. If for some reason you ever decided to go back to stock, the plastic part is cheap to replace.
-OK. Now the fill and pressurize procedure for the 'traction fluid' for the supercharger is interesting. What the heck is 'traction fluid'? - it is the working fluid in the system that is essential to how the supercharger traction drive operates.
... Explanation of the system can be seen above.
