AWD dyno

 

Can we say "eat off the shop floor"....

 

i used a dyno dynamics... i made 188 at the wheels after tuning...

 

On my GSR with 110k, and i/e on a Dyno Dynamics I made 153whp.

 

There are 2 types of dynos. The one has a variable load on the drum that tries to measure the max torque of the car at a fixed rpm and then it does some sample measurements at different rpms. It seems that a Mustang dyno works this way. I'm not sure.

The other one has a fixed load on the drum (weight of the drum) and measures the acceleration of the drum caused by the car. This is the case with a Dynojet dyno.

 

There is a shop in the Vancouver area that has one:

Here is my most recent dyno:



=B18C5 + high compression + Toda Bs + 310 ccc/min injectors + Hondata + Hytech

Nice to hear that they are conservative numbers!

 

OT: Any more pics of the black Bimmer outside?

 

No, I'd say the dyno just "reads" low.

 

The Dyno Dynamics dynometer has what's called a ramp rate, which will change the amount of power that the graph will show...I have ~130+ runs on a Dyno Dynometer. I have a couple of 218whp plots with my old Toda B setup.

This is interesting: http://www.bristoldyno.com/info/whatis.htm

 

That black M3 looks sweet. And look at those big lips on those wheels DAMN.

Numbers vary from dyno to dyno and according to atmospheric conditions at the time of testing (that's why it is most meaningful to look at the corrected SAE numbers instead).

I think the 27% loss is high - it's more like 18% if memory serves correctly.

Most bone stock Type R's will test in the 160 whp range.

I/H/E can get you close to the 180s. The stock R exhaust is a major powerloser as is the stock intake. YOu will get even more with custom ECU tuning.

 

if i ever dropped my burger on that shop floor..i would happily pick it up and eat it again

Yeah I know the conditions affect everything, and I dont think, as you can see, that these numbers are SAE corrected. I think its a must to put it on a Dynojet now, and at least get some corrected numbers on a more widely used dyno. </TD></TR></TABLE>

I'm pretty sure the DynoDynamic numbers are corrected.

It will be interesting to see how it compares to the Dynojet numbers.

The DynoDynamics dynos are nice because they are easily installed (no huge pit to dig) and AWD option is also available at a good price point.

I think you will see more of them in the future.

The most important thing is not absolute numbers but getting the most CHANGE/IMPROVEMENT you can from the baseline all the while keeping the motor at a safe a/f ratio.

this was on skunk2 stage 1's a 2.5" custom catback and cat, jdm dc 4-1, and an aem cold air

tuned on an s200

Bingo.

Jumping from dyno to dyno to get a higher peak # is completely pointless. A dyno is a tool for TUNING.

If you want a better idea of how your car stacks up to other ITR's, go to the dragstrip.

 

Just do timed acceration runs in ONE gear (instead of 1/4-mile). That will eliminate variables, such as wheels spin, shifting, bad launch, etc.

 

glad to see your buddy got his car back together. hope to
see you out at the track!

 

not bad not bad

haha no not yet man, im really focused on paying off all my debt and im doing really good so far so next spring i will have something nice, like a hypeR but i will defiently go to a BBQ this summer..hows things going with you??

Now thats a real clean performance shop

L0L, we should see about getting this meet planned then

Definately d00d. I'm driving back ( ) this weekend. Getting out of this damn 100+ degree weather. The last one along with the last ITRCA was at that Centenial Park right? </TD></TR></TABLE>

HAHA 100 is better than the **** were gettin here mang, yea that ITR meet was the last one i was to..we should shoot for a big one at the end of june or something

I wouldn't even waste time dynoing it again. There's simply no reason to. A dynojet will read higher but who gives a ****? (unless you want bragging rights, but then, you're going to need a LOT more than 165whp anyways)

Just be happy with the car (those numbers look fine for a loading dyno) and dyno again before/after mods so you can see what the mods did to the powerband and of course use that loading dyno for tuning.
