Dont seem to be getting power out of the car Finally got my car tuned. I really like driving this car drives really great on the road. Found a couple problems with the setup though when on the dyno.
Made 350/317 on a mustang dyno.
Specs
347 Ls1
PRC ported LS6 Heads
232/236 114 lsa cam
LS6 Intake and ported TB
42" injectors
3600 stall speed
4.10 gears (Big Problem)

Yeah I know they dont mean ****, Im going to the track Wednesday night to see. Just doing some mock runs on the street it felt like it pulled harder with a taller gear
Unlocked converter and the pull ended before HP peaked.
My car made a whopping 345rwhp on a dynojet through an unlocked converter with the mods in my sig (headers, cam, full exhaust, fast90/90). At the track it seems to be doing decent though.
But report back with trap speeds just in case there is an issue.

Having the converter unlocked causes more power loss through the drivetrain.
If the pull was made to 6700 RPM or so with the converter locked, it probably would have hit 380ish.

What was the DA?
You can calculate here: http://www.dragtimes.com/da-density-...calculator.php
If the DA was pretty bad, I would say you are in the ballpark. My car did 111mph but in 1840 DA. I likely weigh a couple hundred lbs over you. When the DA got REAL bad (over 3000+) I slowed to ~107-108.

Density Altitude: 1721 feet
Relative Density: 95.06 %
It was warm out there, It rained all day there so there was no prep or very little, so I think thats why Im spinning at the line, and just got to time my 1-2 shift better. All in all I was happy just re learning the car last night

Unlocked numbers are definitly going to be lower than locked, but locked numbers dont mean anything unless your running a converter that can handle locking up under WOT conditions.
