It seems like an easy set up, only real problem would be making the A/C style bracket to mount it to the block. Plus you can run a small FMIC if necessary.

Are they harder to install then they look? I cant find many youtube videos on it which means not many people do it.

My brother wants to supercharge his EF with a Z6 but JRSC kits go for way too much and are pretty hard to find at that.


Input?

The M45 is an Eaton

The MP62 is way, way better for this application, but thats not what came with the thousands of JRSC kits that have plagued the Honda and Mazda would for 15 years.
The meain reason anybody bothers with them is because that kit exists. Most people dont want to do the fabrication to mount a roots blower when turbos are better and cheaper, and even less people want to pay the even bigger price for a twin screw.

The reason why sc are popular is that they make better daily applications. A sc is efficient from 1ooo rpms to as many as 2oooo rpms and they are a positive displacement blower. They are also very durable and you don't have to fight heat as much.

Go with a M90 and make some real power.

Very little of what you just said make sense.

because the Eatons are being spun the wrong way.......losing 10-15% eff.

Originally a buddy of mines idea using the M63 Kompressor back in say, 2000 or so.

AKSC was given up on because turbos are easier, cheaper, make more torque and power. The ONLY reason to have a Eaton on a Honda is the cool sound.

I will just smile as you continue to pass bad information as gospel. Maybe the reason you don't understand is that you are so sure of the second hand information you have that you got from buddy A B and C. Have you ever questioned their source. Now be more specific of what you don't understand.

Hmmmm . . . My T25 responds almost as fast as a supercharger and can make 200+WHP.

(I have driven a ZC'd CRX before. It was effing awesome, but, a simple T25/HF manifold will make more power and be only the smallest fraction of a bit less responsive than a supercharged setup.)

Superchargers because they are positive displacement pumps have broader use range. No matter how fast you spin the motor the Supercharger will constanty be creating positive pressure. Turbos have a narrower usable range. Yes turbos are more efficient however a lot of that efficiency is lost due to the amount of heat that they make so this greatly skews their results. If you look at turbo compressor map you will notice that most are considered off the map at 60% where superchargers are lucky to break 60%.

Yes a T25 will respond great but they run off the map very fast (some do and so don't depends on goals). With a properly sized Supercharger this is not an issue.

I am not saying that a supercharger is better. I am simply saying that they both have their own benefits. The main benefit from an OEM standpoint is the fact that most cars operate between 1500 RPM's and 3500 RPM's. At these RPM's a supercharger is just as much as efficient as a turbo. Also in most turbo applications if you are in the map here the redline is going to be shit. With a supercharger that is not the situation.

The problem with turbo applications is you have to sacrifice either top end or low end. It is hard to cover both adequately. With a properly sized Supercharger you do not have to do this at all. Also you can run an electric clutch and only use the supercharger when necessary which greatly increases MPG and drivability.

I will promise you that between redlights a M45 will smoke a T3T4. Horsepower is nothing without response

Umm... I may be mistaken but i do believe that SC lose power at the top end as where turbo's will continue to produce power. Also who races from red light to red light?? LOL go to the track and race and i bet the turbo will win.

if JR would have used the m62 from b18c's on the d16 kits, and m9X(idk the number) on the b18c kits, there would be alot more ppl running jrsc on their hondas.


and that SC bone posted is awesome, w clutched pulley too?

Supercharger is located too far from the intake manifold, you lose the benefits of a supercharger all together. Bye bye instant throttle response. The 3 feet of piping (which is an optimistic estimate) that it would take to plumb a front-engine mounted M62 would add 250+ cubic inches to the volume of the intake manifold.

Either find a CCW rotating M62 and custom fab a manifold or don't bother...at least that's my opinion.
