Anyone know more about these things than me? Seems good on paper.
http://www.autocarparts.com/part/928/42/
Notes:
In Development!


Powered by a screw type blower unit for smooth power delivery.
Includes:
-Blower unit
-Icebox Intake
-Fuel System Upgrades
-ESM Unit
-Battery Tray & Comptech
Battery Tie-down
-All Brackets, Belt and Hardware
Requires new 51R battery.
50-state legal: CARB EO# D-455-15
We Also recommend purchasing the
Comptech Transmission Cooler
Redline High Temp ATF Fluid

Comptech Supercharger Package adds approximately 50 Horsepower and 30 lb/ft. of Torque at the wheels; Torque band is widened to between 3,000 and 7,000 RPM; Very linear increase in boost as RPMs increase; Impressive mid-range throttle response and top-end performance. Completely bolt-on kit requires no engine modifications. Includes tool to modify factory Fuel Pressure Regulator (located in the fuel tank) to the exact pressure required by the Supercharger, and a new Intake Tube to connect either the stock air intake or Comptech Cold Air Intake Kit Utilizes the Eaton M62 blower, making approximately 5psi of boost; Tuning is handled by both the Comptech ACM (Advanced Control Module) and by a Re-Flash of the stock ECU. ACM comes with complete wiring harness. No cutting or splicing of wires is require VTEC is lowered to 3,000 RPM from 6,000, and Camshaft Angle is advanced to 20 degrees between 2,000 to 7,000 RPM only under boost conditions; Requires customer to send in ECU, Immobilizer Module, and Keys; 50 State Street Legal, and CARB Certified for street use in California

I have to admit I was expecting more than 50hp and 30 ft/pounds of torque but this will bring our ridgelines to about 305 HP (Hello Nissan Titan) and 285 ft/pounds of torque :D :) very nice indeed!

I thought supercharging would yeild closer to a 40% increase in HP??

Is 50 hp worth the $4-5k price tag? I don't think so.

If the kit is as complete as it seems and will not cause the RL to explode then I think it is worth every penny. Integration with all related vehicle systems (which this kit seems to do) is the key indicator of a quality product IMHO.

Gotta pay to play. This is not a push rod V8 we are dealing with. We are fighting a battle of technology not brute force.

Hey gang,
I called Comptech today and they stated that the numbers posted on the acp site were not provided by them...acp used info off of another honda kit that comptech sells.(probably an accord) The gentleman also stated that Honda currently has their truck and is doing some testing of their own for something else and they are unable to work on the kit until the truck is returned. He said that the kit will not be available this year for sure. :mad: Sorry for the bad news.

Thank you for the update SUBMAN! There are more than a few of us anxious as hell to get one of these puppies mounted! I'm just wondering if there is a gadget to adjust the psi from the pilot seat!!! Maybe we'll all get lucky and the Honda engineering department guru's pass the transmission stress test with the blower successfully....

no these type of blowers a simple pulley and belt swap is all that is needed.

The really exciting news here is not the supercharger but the possibility of the reflash. I believe serious power can be made from an optimized fuel curve with just a good intake and exhaust not to mention lowering the vtec activation point.

OK thanks everyone for chiming in. Who is/are the real "TUNERS" n ROC?
Well the way I see it if this thing works right then the gains are constant as compared to say a nitro system or a turbo something. Intakes and exhausts changes are minimal if any gains IMO (really just for sound), sorry alexander, and the only thing better than a supercharger is a turbo. From what I have read so far I have learned the following, so please correct me if Im wrong. Turbochargers run off exhaust and therefore are using up energy already being wasted in exhaust to run the compressor. Supercharge uses a pulley driven off engine and is therefore somewhat wasteful, but more consistent than turbo that really depends on revs and exhaust revving up a turbine to run compressor so truly only effective in higher rpms. I'd want the easier to install bolt on supercharger than having to try to plumb in all the piping for a turbo. Gonna wait, but still this thing looks killer.

You are correct Doc, for the most part. Turbos and Supercharges have come a long way. Newer turbos can be had that are auto adjusting, meaning the veins inside move to restrict exhaust flow to minimize lag, and open to allow a larger power curve. All turbos have lag though, and if you are not used to it, can catch you off guard in a turn as it is spooling up!(not fun until you catch on) Superchargers are consistant power, but tend to run out of steam at higher rpm due to effeciency. That said, compressor style chargers like ProCharger, are more efficient and mount like a turbo would, instead of directly to the intake manifold. Their are turbo kits that replace your stock muffler and are quite easy to instal with very little fuss. I am not sure what the brand is, but I have seen them for Dodge and Chevy. I do not know if Summit carries it but I do know that Performence Products does. They don't have a Honda catalog though. One last point. Intakes and Exhaust make a greater difference with theses installs, and are a necessity when you make that kind of change. Remember: air in...air out. The faster you can do that, the more power (in theory) you can make.

I suppose you are correct, but modding the intake is something I am just not willing to mess with. The only way you can get more air in the engine (besides compression) is with either larger filter surface area or less filtration. With all the bad news about K&N filters etc. i.e. letting larger particles through that have some dammage potential I just don't like it. Going to an oil filter? not sure that its any better. Less restrictive inflow has to mean less filtration. None of the systems I have seen have more surface area for paper filters, and I haven't seen data that oil emersion filters can filter out the same microns. Again IMO not worth it.
Exhaust on other hand why not. Less restrictive outflow should not be harmful in any way I can think of.
So add a supercharger =more air in (with same filtration) and freer flowing exhaust=more air out. is what I think is ideal for me.
Oh and thanks for turbo summary. I definately will prefer more consistent power and don't really care about redline or high rev performance. I would not like that corner scenario with a turbo spooling up.

And there's something about the woosh you hear when the Turbo blow off valve releases on the closed throttle! That just says power. Come to mention it so does the high pitched airy whine of a supercharger! This stuff is simply cool.

A few things I noticed. The HP and torque gains are at the wheels. Add at least 25% more to get the crank numbers. That's a lot of boost for only 5psi. It must be very efficient. The redline increases to 7,000rpm, and the extra VTEC valve is retimed to add more fuel earlier. It sounds like a nice setup.

thats exactly the point intakes and exhausts dont add much by themselves, BUT if you had a way to optimize the ecu for there use you would see considerable power from them.

I've had quite a few modified Hondas actually I've had 14 and the last one was a smaller 1.6L with intake header and exhaust it made 142 hp to the wheels but after optimizing the fuel curve and vtec activation and raising the rpm limit to take advantage of those changes it made 168hp. It's the same thing with any engine.

especially in areas where it runs rich the difference between 11.5:1 and 14.7:1 AFR is quite a bit of hp

And from what I understand the baja ridgeline is making roughly 50 more hp with a custom heade and open exhaust, intake and ecu reflash

that's only at 5 psi though..... bump it up to 8 psi and see probably another 30hp to the wheels. on average the eaton roots type superchargers make 10hp to the wheels per lb. of boost.

i am a supercharger fan, have been experimenting on my crx for some time. i really was hoping that the ridgeline blower unit would be the m90 and not the m62. although, im sure with a little modification, i could fab up a counterclockwise m90 blower.

here are two jackson superchargers side by side. one is an m45, and the other is a m62. imagine the m90.. 90 cubic inch blower strapped on top.
