Anyone running a Jackson supercharger?

[acteg]

I am just curious to see how it is working out for you? I have a GSR with a jackson charger producing about 8.5psi. It is all stock except for the installed charger and extra components that come with it (FPR, etc.). I am thinking about using my hondata on this car.

Anyhow is there a map in the hondata base maps that will work. has anyone made improvements that you could share.

what kinda mileage are you getting. The reason I have kept it stock is because I am getting about 30 mpg right now and since it is my daily i want to keep it economical.

Thanks in advance.

A Hondata system works very well when coupled with a JRSC, 'cause you can do away with all the JR "band-aids" and have a finely tunable system. The key here though is to actually get your system fine tuned. :-)

Example: I have a '99 Si with a JRSC running the 8-10 psi Endyn stepper pulley, though in practice it often pushes closer to 12 psi. I'm running the Phillip Skeete 8 psi. JRSC map from Hondata, and it's amazing. But I badly need to get it tuned at part throttle, because my gas mileage averages about 23 mpg with a mixture of city and highway driving. Tuning is everything; not much point in having a finely tunable system if you don't get it tuned.

Go here and here for more JRSC + Hondata info from Hondata's web site.

what is the endyn stepper pulley? same as the jackson pulley? right now I am pulling about 8lb of boost, even though from my understaing this is supposed to be a 6lb system. I have not replaced anything that came with the Jackson kit so..??

I am assuming when you say 8-10lb that this is the range of boost you will get depending on other factors. but all you are doing is putting in a smaller diameter pulley, right?

The JR boost upgrade pulley is a smaller diameter pulley for the blower. Smaller driven pulley = faster blower speed = more boost.

The Endyn stepper pulley uses the stock blower pulley but replaces the dual-belt alternator pulley. It increases the blower speed by increasing the size of the driving pulley. The other advantage to the Endyn pulley is that it's easier to install on a stock JRSC vehicle - you just have to pull the alternator rather than pulling the whole JRSC manifold off the car to swap the pulley. It also reduces belt slippage a little, because the larger driving pulley has more contact surface with the belt.

Regarding boost levels, the stock JRSC kit claims ~6 psi, but it actually runs up to 8.5 psi of boost on a stock B16A2, depending on RPM. JR claims around 8 psi for their boost upgrade pulley, but I've read that it actually peaks around 10 psi.

Endyn says their pulley is good for an additional 3 psi, which is probably about right. I occasionally hit the boost cut of 11.2 psi in a 3rd gear WOT run, so my guess is it tops out at nearly 12 psi, which would be about 3psi more than stock. So I guess I should call the Endyn pulley a "+3 psi" pulley rather than a "8-10 psi" pulley.

I'm running a JRSC on a 97 GSR at 10psi. It has a LS crank pulley and the endyn stepper pulley as well. This all went in along with the hondata after we had to send out the supercharger to have it repaired. The bearings failed and the housings tore up. Endyn did a remarkable job but after the install the piston/rings collapsed. When the housings had torn up the metal shavings were injested by the engine. The engine is currently being built w/ 10:1 CR and 85mm bore to net almost 2.0 liter. However, since the JRSC has no intercooling capabilities I plan on rotating the supercharger 90 deg. to turn its outlet towards the firewall. A liquid to air intercooler will be installed along with a custom intake manifold. Our goal is to reach 300 WHP on pump gas along with a CRV crank pulley.

The main purpose of me saying this to you is that don't try to add too much boost the stock honda pistons aren't very strong.
