That's my car with me driving. It's our MM900R package. Engine : JLT cai, VMP 105mm tb, VMP Apex lid and intercooler, ID1300's billet fuel rails ARH 2" headers Borla Atack 160 degree thermostat My e85 tune Suspension: Full BMR bushings and spherical joints front and rear. Stock CFTP springs and sway bars. Front brakes are swapped out for gt350 calipers and Gyrodisc rotors. Carbotech xp24 front pads Hawk dtc60 rear pads Stock rear rotors 305/30R20 square Hoosier R7
Man I might need you to tune mine. I’m from Texas and the car is pushing I’m sure above 15 lbs of boost as it pegged out the gauge with 2.38 upper and 10% lower. Some tuners have told me that it was fine but I don’t think so. I want it to be safer and have a heat exchanger with e85 and it barely put down 703. Any recommendations ?
Very glad to see an L99 dyno. I have a similarly modded 2011 2SS and was curious what my numbers might be. Plans for a cam and bigger throttle body in the future. Great video.
There is a huge flaw with this Dyno test concerning a C5. In the real world the hood is closed and that Haltech is sucking in hot air from the engine bay. Breathless, Callaway and Vararam are breathing ambient air. Shut the hood for a few min while the motor is still hot. Less o2 less power. That and the ecu is.going to pull timing.
Actually, when the car is rolling normally, the movement displaces the hot air. But on a dyno, it isn't moving. Opening the hood helps simulate what the engine bay temps would be if the vehicle was moving.
How would that intake compare to the stock box with the hood down and on the road @ 100mph? That would be real world. Dyno tuning is always with the hood up and at mostly lower wind speeds.
Did you do the triple pump just because or is it needed w under 1k wheel? Fore numbers said dual pump kit supports 1k wheel on e85. I was hoping to see your low side fuel pressure on the log
The triple is not needed at this power level. For a little more money it future proofs the system if more power is ever wanted later with a built engine. Base pressure is set to 60 psi. The regulator adds 1 psi per pound of boost on top of that.
Anyone know if the magnum 2650 come with a complete kit for install or is it just the supercharger? I got an Camaro SS LS3 so im curious if it comes with heat exchanger, resovior, injectors, etc.
Nice tune. My 2010 LS3 SS made 426 WHP with CAI, headers, high flows, and 3-inch exhaust. The pull was also made in 100-degree weather, so I might've been able to tag on another 5-10 hp with cooler weather.
Mass air flow sensor. A smaller pulley draws in more air which the maf reads and the ecm adds the appropriate amount of fuel. Since the port controller is also maf based, it too will adjust fuel on the port injectors.
Great video man! Ive got a 2011 L99 im looking at doing FBO with and couldnt find a video anywhere of what the gains would look like, Really appreciate you taking the time to go through this.
