CalSpeed 424" LS3/LS7 Goes 611 rwhp n/a, 808 rwhp n20 on mustang dyno
Had a customers 02 Z06 on the dyno with some pleasing results.
Mustang 1100SE (Eddy Current) Chassis Dyno
Best numbers were 611 rwhp SAE N/A. (Not on a dyno jet mind you). 91 octane pump gas.
On the single plate N20 setup we made 805 rwhp but had to shut it down immediately because we are out of fuel with the 255lph intank /w boost-a-pump, now upgrading to a twin-intank pump setup.
Shortblock - CSP LS3/LS7 Custom
CalSpeed (CSP) Built 424" - LS3 Block setup for LS7 head fitment.
4.105" x 4.00" - LS3 Block - Custom Wiseco Pistons (11.27:1 Compression)
6.125" H-beam Rods, 4.00" Forged Crankshaft
Valvetrain/heads:
Tony Mamo was nice enough to take our bare CNC LS7 castings and do his magic to them and do some custom work on the heads/intake since he had them. This was the first set of LS7 heads he had ever worked on, so he was pretty amazed to get 400 cfm on his flow bench. We normally take care of this stuff in house, but our customer is a good friend of Tony (I think he was even in his wedding, lol) and was happy to help him out.
-CSP/Mamo Custom Spec'ed CNC LS7 Cylinder Heads - Hand Finished by Tony Mamo (400.1 cfm), AFR Custom Double Spring (Speced by Tony Mamo), Custom Titanium intake / hollow stainless exhaust valves
-CSP LS7-XL Camshaft, Crane Billet Lifters, 3/8" Tapered Pushrods, Yella Terra LS7 Non-Adjustable Shaft Rockers,
-Ported LS7 Intake Manifold (which made identical to our in house LS7 intake & stock LS7 intake surprisingly. Some setups respond better than others , 60lb Injectors, Factory LS7 fuel rail, 255lph intank pump /w Racetronix Wiring Kit, Boost-A-Pump
-Factory 85mm Z06 MAF, Haltech Intake, 1-7/8" ARH Longtubes /w 3" Corsa Catback, Meziere EWP, UD Pulley, Full accessories including a/c belt on.
-Dynoed on MT ET Streets 28x12.5
-RPM T-56, Triple Carbon Disc Clutch,
-Custom CSP Nitrous System - Fully Automated Trick Performance Progressive - HSW Timing Retard, Custom hidden trunk enclosure.
I'll get a dyno graph uploaded shortly (ignore the spike where it lost signal during run). RWTQ was about 535 on other runs.

I have not tested with no MAF yet. If the customer wants to go SD or try a 100mm setup then id love to try it, but thats up to him.
We are adding a vacuum pump setup to it later this week which I am hoping to see some interesting results on. Should be on dyno again thursday or friday and to the track on the motor n/a this weekend.

We saw zero gain back to back with another stock LS7 intake manifold we had laying around right on the dyno (swapped while still strapped down on the dyno about 6 months ago when we were doing some testing with a new cam that I did for it).
