Got A PD Blown Coyote? Need Some Help.

[Department Of Boost]

I'm trying to get an idea of what I want to offer for pulley sizes for our Coyote application blower kit. Can you guys help me out by telling me what you have? I need to know:

-What blower
-What size upper pulley
-What size lower pulley (probably stock in most cases)
-What you're making for boost
-What are you making for HP
-If it is on gas or e85

Thanks!

Results at elevation so keep that in mind. We get hosed on air up here so have the small pulleys ready for people in higher altitudes. Power numbers have correction factors on them. This was my car back when I had the TVS on it:

-2.3 whipple
-3.125 pulley
-IW dampner but stock size
-depending on temp outside 11-11.5 but I also have 1 7/8 inch long tubes
-depending on dyno and time of year between 660-700
-93 oct

Man, the Coyote compression ratio really makes the smaller blowers work.

Is that on a stock bottom end? What are you spinning the motor to?

I was on the stock bottom end with the 3.25 pulley and no supporting mods and made like 570hp. I now am not on the stock bottom but still 11:1 and spin it to about 7500 with longtubes, off road exhaust, boss valve train, tss gears, twin 65mm cobra jet tb, Jlt intake. FWIW even with JPC being more turbo oriented ever since they took over tuning the car woke up big time and drives excellent.

How much boost did the 3.25 make?

9 sometimes 9.5.

Cool, that is about what I was thinking. I guessed that we would need to run a 3.0 or 3.125 on the M122 to get 550. That's awesome, the blower is spinning way slow with that size pulley.

Thanks!

2.3L whipple
Longtubes/65 CJ TB/127 JLT
Forged 11:1, CJ 11mm 290duration exh cams
2.875in (73mm equiv)+5% OD crank. 6 rib.
Between 14-15psi
104 Sunoco unleaded
19-20 degrees of timing
Killer Chiller/stock reservoir. I did not shut the car or a/c off the entire time.

Blower only, 734hp (at 7500rpm)/ 600ft.lb (at 5500rpm) in 3rd (auto). Spun on the dyno both pulls, so the torque peak is where it regained traction without the surge (692ft.lb). Based on the logs/graph it should be somewhere in the 640ft.lb range.

Car spun its way to 9's@low 140's on et streets, lol. I need to work on that. Fastest 2.3L Whipple Coyote, at least that I'm aware of.

I clearanced the engine for spray, I intend to use it when I get the 330' sorted.

Wow!

TVS
82mm
9-10#
602rwhp
Pump 93

Most TVS cars are running an 82mm upper on the stock bottom end. Some stock airbox cars run 79mm or lower and achieve the same amount boost.
