Those are impressive gains!
Nice numbers, guys!
Can you confirm your mods, buc090705? Your (20+lbs) boost seems pretty high for a stock supercharger and pulley.
Have you checked the lower pulley/balancer?Yep that is it unless it is ported but it isn't marked. Shop was surprised as well. Bought the car used so not sure which is why i wanted it baselined.

my car made 682 / 711 , 93 pump gas
Mods as follows
JLT 123mm intake , VMP 67mm TB, VMP high flow inlet elbow , 2.4 upper pulley @17 psi, Metco double bearing auxiliary idler, ARH LT headers, ARH off road x-pipe, Corsa sport axle back
what do you guys think, can it put down more power with the mods on it ?
That makes sense.yes has lower 10%. stock
upper though

Well, do you just want a number or are you going to take it to the strip?
The strip trap MPH is the real indicator, but I always remind myself that the dyno is just a tool--it gives a number that is dependent on that dyno on that dyno.
I'd be most interested in making sure your current tune is safe, who is tuning it?
It's making great torque on 93 octane, I'd be careful and make sure you're knock sensors are happy with the current timing in the tune.
Too small a tuning window on pump 93 if you're really pushing it.
Respect the octane and the RPM and these motors can last.

All on 91 octane?!? Very nice.Thanks to Cushman Motorsports, Billet Pro Shop, and "back to stock" sales, I pieced together (what amounts to) a VMP STAGE 4 Power Pack (JLT 127mm CF CAI, CFM Twin Jet 67mm TB, VMP 2.4" Upper, 90mm Idler, BPS Oversized & Ported Plenum/Elbow, and NGK TR7-IX plugs). My friend, O.W. Kenobeno, kindly helped install the hardware. Custom dyno tune by Elite Performance And Tuning in Littleton, CO produced 733 RWHP & 713 RWTQ on (91 octane) pump gas.
Those are some strong numbers.

Correct. Unfortunately, 91 octane, is the highest/best widely available here at ~7K ft elevation. Thanks!All on 91 octane?!? Very nice.
That torque curve is nasty!
Thanks! No plans for anything more - not interested in the internal work required to push much further.Those are some strong numbers. Any more mods planned?
Ya that's fair maybe some headers down the road? Does Colorado have the emission tests?Correct. Unfortunately, 91 octane, is the highest/best widely available here at ~7K ft elevation. Thanks!
