Guess the numbers

[voodoo21]

Installed the gen 1 TVS back in the summer and had it tuned by pro dyno in Ft Mill SC. Made 692/678 with the stock TB, stock elbow and stock injectors. Have since upgraded to FRPP 65mm tb, L&M elbow, and 80lb Injectors. Added the Metco auxiliary pulley to help with belt slip. No headers just of road x pipe and jlt123 with a 2.49 pulley.

Post up your educated estimates.......

Tune time is tomorrow @9am

That seems like pretty high numbers for your old mods. Are you going back to the same place for the dyno and tuner?

 

[voodoo21]

Yes, going back to see Dan at pro dyno

Agree, those numbers seem high for old setup.
Going by those numbers you will be around,725/720

Dan at Pro Dyno also tuned my 07 GT500 with a VMP TVS, 2.5 pulley, LM Twin 72mm TB, Lethal H pipe and SLP Pro axle back and it made 711 rwhp/705 rwt. And my A/F stayed around 11.8 above 4500 rpm. I'm going to say 725 rwhp.

Do they use sae or std conversion for the numbers? They both seem high but nonetheless it's just a tuning tool.

+25 hp/tq

What octane and degree of timing on old set up would best answer the question. Also No headers make your numbers seem way to high.

I had the exact same combo with a 2.5 as your old set up did but with headers (stock elbow/stock tb) and had it dyno tuned. Tuner had me at
19* of timing and put down 677rwhp and 696rwtq @ 16psi on 91 pump. The duty cycle was at 70% and a/f was at 12.0. Was running very hard but the high timing and low octane kept blowing out the 02 sensors.

Vmp sent me a email tune to get me to Shelby fest. Justin dyno tuned me at 15* for 629/623. A safe tune and very reliable. Must say I was pleased. So obviously higher octane and timing make a huge difference

I also recently installed vmp 67mm throttle body and vmp high flow elbow with a 2.4 pulley. have not returned to the dyno. But will be hard to figure gains because I won't make it back to vmps dyno in florida. None the less the new mods made a huge difference!

What's your elevation? Sea level compared to 3000 ft can make a huge difference.

 

[voodoo21]

Sea level. Temp was 44 this morning. Clutch is going, torque curve went up and down. Made 705/649. Stock lower pulley, no belt slip hit 19.1lbs on one pull. 93 octane tune.
Time for an RXT
