Not Real2 days agoWhat kind of power is it running at 7psi? I'm interested in supercharging my 20v and was wondering if you had more info on the work done? It made; 120 RWHP in NA form 126 RWHP in NA form with 100mm stacks 184 RWHP Supercharged@8psi Same dyno same settings, I run quite conservative timing so it could be more with some more tuning. Build thread and dynographs here: www.mr2.com/forums/threads/105904-Arowana-s-aw11-4agze-20v-project
When I let go of the throttle, the bypass valve opens and the supercharger is vented. That whats make the sound + the engine is not making any sound then so the supercharger is more audible. The bypass does not open completely, but is modulated so that there is a few psi of boost in the plenum, increasing throttle response. That's why it "hisses"
"Угон Харлеев: This is a wrong setup..." This is a 4age blacktop (5 valves per cylinder, 4 throttles), it newer had a supercharger so how can this be the "Wrong" setup? I can't have "Air filter>MAF>Throttle>SC14>engine" as that would require me to remove the throttles and instead put a single throttle before the supercharger. I also don't have a MAF as i run speed density algorithm for injection (MAP only) . This system gives better throttle response due to the throttled volume being much smaller and the bypass valve maintaining a slight boost level in the plenum even off throttle.
I have a bypass valve, when the throttles are open less than 50% the bypass valve is fully open. Between 50%->95% it starts to close linearly and >95% its fully closed. This way I don't get dangerously high pressures in the plenum and I don't destroy the supercharger or the belt. The supercharger is turned of during light duty driving (electric clutch) See "High boost bypass arangement" here: www.jagweb.com/aj6eng/supercharging_article.php Video of the bypass valve: ua-cam.com/video/UhvcJjKG-38/v-deo.html In this video, look at the "pwm" log value, its the supercharger bypass valve, 90% fully closed, 30% fully open ua-cam.com/video/5S28cKT45cs/v-deo.html
Ese sonido ufff 😍😍😍

DUUUDE....i have a 4agze sc aw11.....HOW TF DO I GET THAT BYPASS SOUND 😭😍😍
what kind of pulley you used to limit psi to 7?
Is there a build thread or blog for this build?
That sound when revving down is just.. eargasm.. is that the sound of the supercharger or the engine?

In this video, look at the "pwm" log value, its the supercharger bypass valve, 90% fully closed, 30% fully open
