Why did you do the pull in the wrong gear?

Isn't 3rd the right gear for a 5speed?

 

The 5MT should be in 4th. Its closer to 1:1 than 3rd.

na 3rd is the correct gear to pull on a 5 speed if you had a 6 speed then 4th would be ideal

 

Good practice is closer to 1:1.

 

Especially on a dynojet. IIRC they don't make a model that's load controlled. Lower gears show higher power. They don't call them "Disneyjets" for nothing.

Everyone dyno's 5MT's in 3rd.

 

That isn't true.

The dyno is at 5200 feet in Rio Rancho, NM. I'm not sure I trust the correction factor, simply for the fact that the last time I saw a car dynoed there, the temp reading on the dyno was about 30 degrees lower than ambient. Not sure if they've fixed that since. Still, the uncorrected numbers are solid.

 

I agree that any car should be dynoed in the gear that gives closest to the 1:1 ratio, which is 4th (.972) for the 5MT, rather than 3rd (1.296).

As a guy who has made many, many dyno pulls on a big turbo car. A 4th gear dyno back to back with a third gear will usually show higher torque because it loads up the turbo earlier. The HP is virtually unchanged. There is no reason to dyno in 4th unless you like having your car running WOT longer.

 

That all being said, nice numbers especially for only 23 PSI. Your tune seems like it could use some work. I'm saying that because of the big black puff halfway through your pull. And, because of the smoothing on the gragh being @ 5 already and still looking like the mountains.

I'm not knocking numbers. But it generally takes more than a standard walbro 255 and 850cc injectors to break 500 awhp. I know from experience. You should throw some bigger injectors on and a bigger fuel pump and I'm sure this thing'll shine.

Sorry, wasn't knocking the numbers at all, I bet the car is a monster to drive past 4000rpm! I was just asking to have all the criteria in the post for relevance.

 

In Denver, at 5800ft, we get corrected at 1.15 (15%) at the most popular Subaru shop, so I was simply wondering why they chose 20%. It's important to have that in the post for people putting mods together based on a number they want to hit.

 

IIRC, the DynoJet has some weather station that dynamically calculates correction? Based on the uncorrected and corrected it chose 20% that day.

 

435whp uncorrected * 1.20 (or 20%) = 522 whp corrected

 

I also think the peak torque and peak hp rpm numbers are wrong looking at your dyno chart, it's much better than what you put. This is what it looked like to me...

 

519 hp @ 6600rpm

430 tq @ 4700rpm
