TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

How many inches Hg are you guys reading at idle?

 

Anywhere between 19-20 if everything is functioning properly and is nice and tight.

 

Dudes, got a dyno appointment right after work tomorrow.

 

Nice. I think I'm still on for Friday. I have low expectations. It'll be hot and humid.

 

You can just use the weather report as extra bragging. "Oh it was 120 and humid, but I still made 360whp" ... or something.

 

Make sure the show the graph in SAE smoothing, and RPMs instead of MPH. Woot

 

Can UCON disable the speed limiter for 4th gear pulls?

 

How's the weather been? Are we all entitled to one guess? If its 80 degrees, 4th gear pull, I'm tossing out 435 RWHP......(or hopefully more)!

 

You bet. I buried the speedo needle in 5th last time.

 

I’d be over the moon with that. Hoping for cooler weather tomorrow but looks to be around 80 in the evening anyways.

 

I don't have any real basis for that guess, just throwing it out there! Seemed like most trucks running all the conventional mods 2.5, fuel injectors, bolt on goodies were hitting 365 at the rear wheels. You've got the highest maf score by far....still hoping there's a correlation there.

 

Max MAF g/s x (whatever that number is that I always forget) = BHP.

Multiplied by approximately 12 to 13% drivetrain loss, and we should be in the ballpark of his will horsepower.

@Athlaos how close are your tires to stock dimensions?

 

I think the multiplier was 1.18 hp/gps. His latest posting was 444 g/s. So 444*1.18*.87 = 455ish. I estimated down for other factors.....but it would be cool to 450ish!

 

266 to the wheels

 

No way it’s 450 rwhp. I’m thinking more around 380 rwhp. Depends on whether dynodanamics or dyno jet. Tires are a factor too on dynos like @Torspd said. But maybe 400 torque. Those stock internals would be hurting north of 400 especially the rods and Internals don’t lie, they tell you the truth real quick.

 

My money is around 380 - 400.

 

Okay so I think we have so far:

@DocME 435whp
@TRON 380
@Kelvin 266

I'm personally going to say a nice round 400.

 

They are 2" bigger diameter.

 

I'll be getting some dyno pulls after my cams are installed, and tuned with the VVT working. The shop where I had this stroker engine dyno'd on OEM ECU, then later under Haltech control, is the same place that I'll go again. Due to consistency alone. Not necessarily a fan of Mustang dyno's, but the scientific process must be followed as closely as possible.
