What's the average/your baseline full-oem/stock dynojet numbers? & convert to fly HP?
 

Just wanted to know/see what your (or the average) dyno peak whp numbers are around the world, for full-stock/OEM. Preferably the popular Dynojet (but other popular dynos are welcome too). I am sure they will vary due to altitude of location, weather, humidity, if the dyno is in calibration and of course the car itself. But, want to see if there is at least a good similarity to other stock/oem dyno whp numbers around the globe with the same kind of dyno.

Also, how would you calculate/convert any new whp from dynojet dyno numbers (let's say, after tuning, parts, etc., etc.), into an estimated flywheel'esque type number (or, like how the car is marketed from toyota/subaru/etc)...idk if it's exactly flywheel)?


EG: Is this correct?
Our cars supposedly make 200 fly hp stock. And, let's say the dynojet average is 160whp stock. Now, let's say, after sometime, after adding aftermarket upgraded parts and tuning, the new numbers are 200whp on the Dynojet. Do I just multiply that new 200whp by 1.25, to get me an estimated flywheel hp of 250fhp?? (the factor of "1.25" was attained from dividing 200fhp by the Dynojet's 160whp).

Pretty simple questions...just want to make sure, hahaha.

Anyways.. would be nice to know what the average Dynojet peak whp numbers are and what everyone's been getting.

I go on the basis of drivetrain losses are about 40hp. That's on a dyno that is about 160bhp stock. My car made 230bhp at the hubs so I reckon its about 270bhp.

I guess the better way to look at it is to calculate a % increase in power and then do that to the standard 200bhp claim.

Isn't "calculating the % increase of stock whp vs new modified whp, then doing that to the standard 200bhp claim," pretty much the same thing as I have already calculated in my op example; of getting the factor first by dividing the standard 200bhp by the stock whp, then using that factor to multiply it with the new modified whp. Eg:

Calculating the % increase in whp power first, and doing that on the 200bhp:
177whp(ex: a dyno from new parts/tuning) / 160stockwhp = 1.10625
200bhp * 1.10625 = 221.25

My op example:
200bhp / 160stockwhp = 1.25
177whp * 1.25 = 221.25

Same results

Still want to hear what everyone's baseline full-stock dyno numbers are though :)

125 whp on dyno dynamic

I usually assume a 15% loss based on the very consistent 170-175whp baseline pulls on Dynojets I have seen. I made 181whp using the VitrualDyno on the OFT Stage 1 tune and 217whp stock on e85 with the EL e85 tune with the same measuring tool on the same road. This is about a 20% bump in power on corn.
