Cammed L99 vs Cam/spray LS3 Gen 5's Dyno tuned the Ls3 after the spray install and made a pull to see how it liked it....lol. Pretty good I'd say. He put it on me as expected. His car put down 601/655 on the 150 shot, 480/455 on motor. I put down 474 unlocked.
50ish to about 160ish (for me, he ran up to 177).

He is on stockers too, for now at least or until wheel hop on the spray claims the right rear! lmao. Yea at 601/655 its a hoss.

Nice respectable loss. Surprised your car made 474rwhp unlocked though: you should contact Mast and let them know they have a new record as the highest I've ever heard for a VVT cam unlocked is 440rwhp. Every magazine that has used Mast's setup get 420-430rwhp with there biggest VVT cam and most used FAST intake and big tube headers/ no cats. unless they came out with something new in the last 6 months?

At work we are actually a dealer for Mast. I picked up about 17 rwhp with porting the intake and working the tb a little bit, not porting but milling the backside to correct the factory 8* angle it sits at on the intake, basically I mimic'd what the vararam power wedge does. I believe they told me the specs on my cam were 230/244 on a 111. I baselined at 436 after the cam before touching the phaser tables. After tuning the phaser, I ended up at 457. Then I milled the tb, ended at 463. Ported manifold and ended at 474 after some timing tweaks. I did dyno with it locked and it put down 481.

Awesome race, he must be happy with how that car pulls now!
You're gains from locking the converter are similar to what they saw when a friend's car was dynoed. Some people post up like a 30 rwhp difference between locked and unlocked. Are those just really loose converters?

Driveability is awesome, very tight converter. The slip ratio is going to vary thoughout the rpm range though as the converter becomes more efficient with more rpm, more slip at lower rpm. What cant be measured on a dyno is the torque multiplication you get from the converter!

Ours calculates this as well, it uses engine rpm vs roller rpm, thats why the variance between locked and unlocked isnt really much difference vs some other dyno's. Where its gets hard is when you have a converter that flashes 4000 or so, and basically it flashes on wot and hovers at that rpm until it reaches that point of efficiency where it tightens up some.

Hey Rhino, nice to see ya today. You made me jump back on here. At least that is what I told my wife.
I think the power gains your are seeing on the dyno were from that furry friend running in the squirrel cage behind the rollers.
Had to be 20-30whp from that.
