T-Rex, Stage 3 Heads, Fast 92/NW92, full bolt on #'s seem low
I'm just a little concerned about my combo, I know that dyno numbers don't mean anything but I felt this combo should have put out more. Opinions welcome. Drive ability is also not as great as I would have hoped for, for as much as I spent. I won't say where I went to preserve the integrity of the shop. If these numbers sound legit to most of you than I may be just talking out of my *** for no reason but that's why I'm posting to make sure I'm not blowing smoke.
Motor/exhaust
T-Rex 243/250 610/615 LSA 110
Stage III Patriot Heads (64cc not %100) but they are Stage III for sure
Fast92/Nick Williams 92TB Combo
FAST TOYS 104mm lid/Chris1313 Ram air setup
UD pulley
Mezier Electric Water pump,
NO power steering
NO A/C
Kooks 1 7/8 stepped Headers, Kooks catted Y, open cutout
BR7EF plugs gaped .030
Lingenfelter timing tuner meant for a max effort motor only setup and spray when I want just a little more
Driveline
T56,
Monster Level 4 clutch with billet lightweight flywheel
PST aluminum driveshaft
MWC Fab 9', Wavetrack, Aluminum Center section,
Moser lightweight race axles, Gun drilled, Outer part drilled also for weight savings by MWC. These were the lightest, strongest axles at the time I got them
4.33 gear
28' Hoosier QTP with Lightweight Bogarts Welded RT
Fuel, VP 110 full tank
60lb injectors,
(2) 255 Walbro's with the racetronix kit
Speed density tune on VP110
Timing was said to be very aggressive. I don't know the exact timing
Numbers were 436rwhp and 390rwtq on a DYNOJET, I dynoed 440 on a mustang dyno 2 years ago? Shouldn't I have made more on a Dynojet? With a 175shot numbers were at 575tq and 580tq.
I was told that the combo was an aggressive tune but it doesn't seem like it. Is it just me or does this combo seem like it should have put down more? Everything installed on the car were the lightest material's I could have put together.
When the car was picked up the same amount of full was still in the tank? Shouldn't a tune that takes supposedly all day require at least a few gallons.
Opinions wanted. Thanks you

Stock LS1 bore?
If so I'm wondering how you have Patriot III's on it? My Patriot III heads had 2.08 intake valves which I wouldn't think they would clear anything less than a 4" bore.

The heads would not be my first choice although some have made good power with them. I believe it is just a quality control issue being why they get a bad rap. The catted Y is also not helping with power. I would be more interested in seeing trap speed along with the Density Altitude. That setup should do 122-123 depending on the air and weight of the car.

Stock LS1 bore, Car's weight sits at about 2950, maybe a little lighter. I expect to run high 10's/low 11's on motor. It's basically a max effort motor setup with spray if I need it.

Patriot heads have to been known to be hit or miss.
And you have a few parts that are stealing power but adding strength at the same time.
Perhaps the shop that tuned it filled your tank back up?
Check your invoice to see if there was a fuel fee or something?
I would go to whomever did the work and ask them any concerning questions.

I pretty much agree with everyone. The numbers are low and the heads aren't ideal but they are just dyno numbers. Run it at the track and let's see what she's got.
I'm going to be testing my max effort "cam only" setup this week. I'll report back.

Mine drove great.. It's all in the tune..
11-1 cr 347
Old Absolute Speed 2.5 heads from 2003
LS6 intake with ported TB
Edelbrock 1 3/4 stepped to 1 7/8 headers
3" X-pipe
80E with 3,600 verter
3.73's with 30" drag radial
Drivability did get better when I went from 3,600 stall to 4,500. It got even better when I went from the LS6 to Super Vic. It also improved when I went from 3.73 to 4.56.
It was a real turd though when it has the stock verter in it. It did still drive nice, no surging etc. But a full Open loop SD helps.
