GEN 2 yet another SPD Dyno Plot

A point of clarification:

did you dyno stock (no SPD) and then dyno with ONLY the SPD adapters?

I’m in at least partial agreement with @Gsteve, I doubt they hurt anything, but if you tuned and put the SPD’s on at the same time, we’re only guessing if they’re actually producing real world numbers.

Seems he did NOT which makes his claim nonsense data.

Not necessarily. His installation of multiple changes at one time makes it very difficult to know what was contributed by the adapters, the tune and the combination of both. To clarify, the ‘tune’ means his entire tune package.



According to Whipple, their CAI is actually worth real hp, not smoke and mirrors and they assert they actually see HP from -just- their intercooler from the stage 1 package. If you break down their numbers for these component parts, allowing for some variation, you can end up with some understanding of what they may contribute based on his truck’s results.



It’s not exact, but the numbers are what they are.

let’s take Whipple at their word and face value.

I don’t have the thread in front of me in which Whipple gives numbers they’ve seen, but, we have a hard / fast back t back from Toad

347 to 410 or 63 hp.



let’s take 10 away for each CAI and Intercooler, that’s 43 hp left between the tune and the SPD adapters. But look at Toad’s post here: http://www.fordraptorforum.com/f261/yet-another-spd-dyno-plot-59557/#post1234820



note that his comparison truck peaks at 406hp, Toad peaks at 410, but his baseline is higher by over 20hp. Max tq are also similarly consistent on the tuned truck.



This suggests to me that Toad has a better baseline dyno run, not necessarily more power from the SPD adapters. I’m having a hard time rationalizing Toad’s suggested +24 hp here based on the numbers at hand. Is it possible that he had better dyno conditions up front, possibly a weaker truck off the line and the SPD adapters compensated for an engine that was a few ponies under the curve? maybe. Or maybe he had closer to the Whipple test truck conditions and the spd’s are worth a few ponies. If Whipple’s claims are to be believed, and I have no reason to not believe them, then the SPD adapters don’t hurt, but they aren’t +24 hp. If this were a choke point in the exhaust, relieving that choke point would show significantly more power up top, not 5 hp. Another observation; Toadster’s truck has acquired a torque dip just after peak torque to about 4200 rpms compared to the other truck. It comes on earlier in the earlier dyno run, but torque hits max, then dips, then steadies out. The Whipple test mule curve is significantly smoothed but doesn’t show evidence of this.



I think if @Toadster were campaigning a Black Raptor, which everyone knows by now is the fastest color Raptor, he would probably have seen another 9 or 10 hp.


@Toadster’s numbers aren’t bunk, but they aren’t definitive or conclusive. They are data points and provide a basis for at least some numerical data to use in considering the purchase and install of these adapters.
