I want to get my CR dyno'd

S2KCRick · 03-19-2009, 12:04 PM

Anyone know where in the SFV i can get my car dyno'd. I'm looking to get a SC installed, but i want to see my numbers before i do that. I want to go to a different place than the guys that are installing the SC for me, just to have a "second opinion".

Let me know, thanks.

Hey Dude heard this guy is the S#!t when it comes to Dyno testing, I haven't got to use him yet still modding my car. Chruch Automotive 310-713-6171

there is nothing to dynoing a car. put it on the rollers, strap it down and make some pulls..

S2KCRick · 03-23-2009, 10:13 AM

I just got it dyno'd. After 3 pulls, the final results were 225hp and 156 lbs of torque.

Get this, they had a record of a 2003 s2k that they dyno'd and compared it to my results. They had 6 pulls on the 03, with 208 hp and 132 lbs of torque being the max.

I thought it was strange to see that the numbers on the ap1 were that low, I was thinking it would be some what closer to my numbers. But i guess there is plenty of factors that would cause it to be low, ie high mileage...

225rwhp from a stock f22 is pretty unheard of... where did you take it?

The place is called Speciality Z, they do a lot tuning on nissans. They were second on the list of places that i got from the site you referenced.

S2KCRick · 03-23-2009, 10:26 AM

I also had the air box cover off when it was dyno'd. I would think that having it off would be a negative affect.

nah, not if the hood was up...

225rwhp would mean either your car had only 5% driveline loss or your f20 is making 265 at the crank...

somethings not right

S2KCRick · 03-23-2009, 10:48 AM

Hmmm, has anyone else had an 08 CR dyno'd? The guy running the dyno said something similar, but more along the lines that Honda is underrating the HP on these, based on my results. He was saying that the HP is probably close to 245-250 at the crank.

Im gonna have it dyno's again at another place too, that has a different type of dynometer. This place called Extreme Automotive (www.boostpros.com) uses the Dynapack Evolution 4000 chassis dynamometer, which is supposed to give more accurate results and they say that the numbers will likely be lower than other dyno's.

turbosix · 03-23-2009, 10:52 AM

most ap1s i have seen put down right around 20x rwhp so the AP1 numbers they had before are pretty accurate

S2KCRick · 03-23-2009, 11:29 AM

So like you said, I guess my results are not the norm. but i guess there are some other factors that couldve affected the results. Maybe the tires? Better traction on the roller with the Bridgestone Potenza RE070?

I agree with T6... something's different to the tune of 15-20 hp. I can't imagine tires having any effect, let alone 15-20 hp worth.

Either your motor is cranking better than everyone else's, or the dyno is overstating.

turbosix · 03-23-2009, 01:05 PM

the dynapack is going to read pretty differently than a dynojet or a mustang dyno. from what ive read most dynojets are within 1-2hp of eachother as long as they werent damaged in shipping. other than that if the operator is using the weather correction factors wrong it could skew numbers. ive heard of some shady performance shops fudging with correction factors to give higher numbers than normal to show gains when there were none (kinda like how basically every s2000 intake, exhaust and cam manufacturer has "omg 15hp peak power gains!!" on their websites but no one in the real world has ever been able to duplicate it)

so... i guess we'll see when you go to the dynapack.

S2KCRick · 03-23-2009, 01:46 PM

So how does slippage on the dyno affect the numbers? If my tires are slipping more than usual, would it skew the numbers to be higher or lower?

I am due to get a new set of rubber real soon, so maybe thats what could be making my numbers higher. IDK.

TheSoundMan21 · 03-23-2009, 02:01 PM

Im going to guess slipage = a less number in hp

you arent going to slip on a dynojet with 225hp. my friend's 03 cobra had a little issue on a cold day with tire slip until his drag radials warmed up, but his cobra makes 460rwhp and 490ft-lbs of torque...

If your tires were slipping, I suppose that would cause lower numbers. But I doubt your tires were slipping. As an aside, if your tires were worn enough, you might even have a larger contact patch... which is good (at least on dry surfaces).

I would be willing to wager a LARGE amount of money that your tires have nothing to do with skewed numbers.

turbosix · 03-23-2009, 02:19 PM

either their dynojet is wack (unlikely) or they are (knowingly or not) using the weather correction factors incorrectly.

S2KCRick · 03-23-2009, 02:30 PM

You know what, i think it is the weather factor. It was pretty humid and cool out, around 65 degrees or so. It was cloudy and gettn ready to rain. I guess that could be it. Thick cold air gives better performance right?

I have the CR in the shop right now, these guys will be using the dynapack, then theyre gonna run the test again after they put on the Vortec SC. I should have the dynapack results tomorrow. SC should be installd by end of week.

turbosix · 03-23-2009, 02:36 PM

before and after numbers on the same dyno are going to be your best bet. let us know how everything turns out fo sho

TheSoundMan21 · 03-23-2009, 02:55 PM

congrats Rick

S2KCRick · 03-24-2009, 04:58 PM

I just got the "before" results from the Dynapack:

190 hp
135 lbs

Thats a good 20% loss. So the SC should add about 130hp, putting me at 320hp when its all said and done. I should have the "after" results by end of the week.

S2K Reborn · 03-24-2009, 05:07 PM

190 sounds a little low for an ap2. Mine dynoed 206

what kind of dyno did they have?

S2K Reborn · 03-25-2009, 08:49 AM

Not for sure, it was way back when I got the car
