N52 Dyno

2006 73.5k miles 3.0si

Only have the dyno sheet for the last run. I think the 1st one was 233 on 4th and the second was 231hp on third gear.

3rd run picture below
4th gear 235.02hp and 225.94tq
Pretty sweet numbers IMO. Need reading a lot of post about the N52 being underrated.

Pictures are uploading to my photobucket. I'll have them up soon

Oh yeah, mods:
K&n drop in
Carbon filter removed
DTC was all the way off.

Are these even considered mods

I've never really looked into how the N52's dyno but seeing as it's rated at 255bhp and you put down 235whp, I'd say that's pretty good!

Appreciate the info. Do you happen to have the numbers with SAE correction?

Most Dynojets will allow you to save the file on a USB flash drive. I'd recommend getting it. You can then display whatever info you would like - data with various correction factors, rpm, speed, AFR, etc.

This is consistent with the 1-2 other dyno's I've seen over the years, both N52 with 6MT

I know they saved it. I'll ask the shop and see if they can do the USB, as well as get me some SAE Corrections. This is my first dyno run, so thanks for the suggestions.

I have been communicating with AA I beleive I need to do a run on a mustang dyno. Aparently the numbers are more accurate?

Dynojets are an industry standard and fairly consistent. I don't doubt AA, but you can't go wrong with either.

(This is not directed at OP... I'm using "you" in a general sense here): You can't compare Dynojet numbers to Mustang numbers, and you have to understand what the numbers tell you and not take them for face value. My car may do 285 whp on one dyno, but 295 on another. What you can use the run for is to establish a baseline from which to compare future runs. It takes two dyno sessions to determine a delta. You could compare two cars on the same dyno with similar atmospheric conditions, or you can compare two sessions of the same car to see how your modifications have affected your power. You can't make a single run and say "my car puts down x power" as an indisputable fact. I'm guilty of doing this, because that's what the average person understands, and once you start modifying your car it's the first thing that someone asks. It's not correct though. It's also incorrect to say, "My car gained ___ horsepower with these mods." You should say what percentage you gained, and it should be a comparison of either your best runs from each session, or the average of each session. Apples to apples, not best to worst (which unfortunately a lot of companies will do in order to sell you their aftermarket parts). Runs vary wildly. As an engineer, I'm extremely passionate about posting correct data, but I also understand the importance of being able to speak the average person's language without boring them with an explanation of the numbers. I reserve those discussions for those truly interested or experienced.

OP - Long story short, you made a good call to get your car dynoed to establish a baseline, and you'll see the return on your investment when you make some modifications and hit the dyno again.

One more thing, SAE is generally the correction you want to use, because it's the commonly accepted standard.
