I even posted pics in a different post.......... Eaton M63 if it matters to you. |
Re: electric clutch on a Sc
:y
In all honesty. it is nice having the switch to turn the S/C on and off and go back to N/A. Just some things to be aware of. -N/A with the S/C just sitting there slightly freewheeling is a LOT less power than if you were stock N/A -The engine doesn't like the S/C being turned off while the engine is running. It jerks and hesitates (stalls the very odd time if rev's are low) because there is all of a sudden a very big block in the air passage that wasn't there a second earlier...and the ECU can't compensate that fast. It goes to N/A mode about 2 seconds afterwards. -ECU doesn't like switching. It adapts to Boosted. Then when you switch to N/A it tries to relearn everything. Then when you go back to Boost, all the N/A values are rewritten again. Stock computer really doesn't like the change. *My car is MAF'd so i don't know how a MAP'd car will react in this. -Standalone is the best way to go if you are going to be switching it on and off all the time. Mind you, running N/A then hitting the switch is a lot like nitrous. Instant power! and you can do it over and over again and never fill up a dumb bottle ;D |
Re: electric clutch on a Sc
simple part I'm gonna tell you about, Benz bypass valve, we took over the Intel processor with Radio Shack parts.

Re: electric clutch on a Sc
my appologies for being a dick. i was thinking more of a centrifugal supercharger than a roots style.
|
Re: electric clutch on a Sc
my ford lightning had a bypass valve that opened up when you wern't on the throttle so the sc just turned with very very little load. I do believe this is what Mista is talking about, I also believe he has used these superchargers before and is very knowlagable on this subject although I have never seen one mounted up on a engine before. +HINT HINT+

Re: electric clutch on a Sc
Ford uses the Eaton's with built in bypass to the blower casing......
My plate which requires a custom header, only thing holding me back right now, working with SMSP on the issue....... http://bonespec.com/Honda/AKSC/AKplate1.jpg The original design that cleared the stock manifold (like the one that sold on ebay!) but due to being mounted out so far it breaks the mounting bolts...... http://bonespec.com/Honda/vids/aksc/P3030021.jpg |
Re: electric clutch on a Sc
Hello Nooblets......
Two well known superchargers come with an electric clutch. The Eaton M62 from the Mercedes Kompressor series and a Toyota Corrola (?) AZG??!?!?. I don't know the Toyota info cause I havent owned one, but have seen it in person as a STOCK JDM setup. Back to the M62. It moves .75 liter of air per revolution. You need to have a LARGE crank pulley to get serious PSI on a motor 2.2 and larger. I am using a 7.25" crank pulley to its 3.625" pulley for a 2-1 ratio and getting only 8-10 psi with no intercooler. When switched off, it idles PERFECTLY. The rotors simply freewheel. I still have plenty of fun with it off compared to when the SC wasnt installed at all. I have hooked up a vacumn switch that turns the SC on when I get near 0 vacumn, ie on the gas. I went from 100 whp ? torque to 155 whp 175 torque. Here is a thread with pics https://www.homemadeturbo.com/forum/...?topic=52953.0 |
Re: electric clutch on a Sc
with the current Honda D series setup, we are only seeing 7-8 psi at 11-11.5K blower shaft rpm intercooled, yeah need a 2:1 drive ratio but the large clutch pulley prevents it.

Re: electric clutch on a Sc
Can Hondas have custom LARGE crank pullies made? Or do you have to depend upon some sort of dampener pulley? Subarus don't "need" a dampender crank pulley, so I just had a huge ass pulley milled for me.
My plan is to either go to a 2.5-1 ratio (which means a HUGE 9.25ish crank pulley), or a twin supercharger setup for 18-20 psi with front mount IC. Yeah I know turbo would be easier at that point, but it will be cool! |
