[XXX ZL1]

Finally put the car on the dyno to get a baseline. I’m running a Maggy 2300, 3.15 upper pulley (stock 80mm is 3.2), 2 inch ARH full system, 103 inlet, and rotofab big gulp. Setup made 12 lbs on the dyno. Car made 703 rwhp and 709 rwtq on 93 and NO meth. Fueling looks good here and I will work on timing tables on the street/track. Car will take another 3 degrees easy, but with the fuel limitation of the stock cam I want to inch timing in and watch fuel pressure. Air/fuel was half point rich also, but I’ll clean that up when I get on the street and can watch pressure.

Air temp and MAT temps is where this thing shines. Temps are much more manageable over stock blower. Very minor climb during the dyno pull and recovers well, something the stock blower doesn’t do well on the dyno.

I think the car will make 740 rwhp range with fueling and timing cleaned up. As long as stock fuel system allows it. Lol. With the pulley it’s running I’m not even scratching the surface of what this blower is capable of. Plenty of room to grow!

UPDATE- Low side starting falling pressure past 700. Commands 73 and fell to 68 psi. Adding JMS voltage booster I got from Ted Jannetty to take care of low side issue. Then back to tweaking.
