dyno and tuned...= )

i'll roll

maybe you can count me in, might be helpn someone with yard work

well come on out, always good to know what your dealing with and get some proven numbers for your car.

[Echonova]

I'm in. I'll have to bring my two younglings though, so I won't stay all day. Need to know how many tire shredding Hp's the stock SR is putting out. LOL

[VickNotic]

anything being cooked.. ? music..? BBQ ??

hey thats fine. bring the younglings on out, and stay as long as you can.

[redrumracer]

i believe we are going to have some food and drinks out there

[big mac]

ill probaly go. how diffrent are the number on this than the dyno jet?

[SEAN]

watch yourself down there...I got stopped down there and the only thing he could cite me for was window tint...the cops are ARSES down there...they sit up on 316 just waiting for you and any excuse to make money for the town...

[dynoman14]

Sleeper,
Hard to say as I have not had many folks with comparitive data. Sheets were either old or not the same exact build although bring yours if you have them.

I would say that on my ARCA cars the Jet that I ran on in Charlotte was a lot easier to spin up and therefore made the torque curve fatter on the bottom and a little easier to get top end power.

The wheel on the SuperFlow is 3500# and not real easy to spin up so the torque curve generated is almost identical to the acceleration what you would see on the street. Time to speed should be withing about 1% of tested results if gearing and tire diameter are recorded properly. It was designed to reproduce these parameters pretty close to real time / real life.

This dyno is really and instantaneous accelerometer 2500HP / 250mph. The sampling rate is on the order of 10,000 - 1,000,000 times more data per run than almost all other publicly purcchased chassis dynos. I use it for very basic HP and Torque curve generation although there are many more uses for it's data gathering capabilities.

I guess you could say it would be like comparing a magnifying glass to an electron microscope in terms of precision, accuracy and data analysis when you compare sampling rates.

For 99.9999% of the world any dyno will give you the results you are looking for. In my case ( I am always the .00001 ) I needed to know how many MPG's I could save by changing air bleeds in a Carburetor by .001", and also how .1# of fuel pressure would affect the power level and fuel consumption at 200mph or how much power is gained / lost by changing gear pitch by 1 degree in a ring and pinion set or transmission gearset, How much power is gained or lost with 1#,2#,3# of change in tire pressure. This type of work requires a scientific approach & A-B-A testing with absolute repeatability and that is what I have.

Long story short...the SF #'s should be a conservative but accurate measure of what your car will do on the road and if you run 50-150mph in 5 seconds, then your car will do exactly that on the street. If those numbers are correct than you can infer that the torque measurments are accurate and then the HP calculations should also be right on.

As far as goodies we are still working on the particulars but will post as soon as it is all ciphered out. Next day or so...

Look forward to having y'all out.

I caaaan't..... April 5 is 4NGIEFEST at Stone Mountain.... (big BMW meet that I said I'd be at months ago). You guys have fun!

[chava_rx7]

HMMMM.. ill go, wana c wat my car can put out..

look for a stock red 89 rx7 N/A

[Thighs]

i wanna come. what time do you think you guys are closing up?

[wunquikser]

put me on the list..this place is closer to me than any other places..

[dynoman14]

We will prolly stay running til as late as we can, last night we made our last pull at about midnight and the Cops did not roll up so maybe we can run til 9-10-11 if we still have folks to run...

My plan was to see how many cars wanted to run and if there were too many we might select out who could come back on Sunday after lunch??? Just an idea.

Just wanted to repeat, can't run 4wd / awd Sorry...

Just a quick update, hotties run for 1/2 price and topless hotties run free!!!

Did I just say that, Oh hell yea I did !!! Sorry I am just that way...

BTW, I have race gas and alcohol if anyone need it, It is VP got some nice gas pretty econo at $6 gal. will support 12:1. We hove some other flavors also for boost and high speed stuff. Bring your own jug if you want to take it with.

Later,

Is this just pulls? Or tuning What octane race gas?

just 3 pulls

[streetstuff]

i will be there with 2 cars

[WhiteAccord]

Just wondering do you guys know how to dyno an auto?

YO YO Put me on the list. I wanna see how much the Talon is putting down....

I think all of the Athens folk go first, as we were the ones who were there with open arms....LOL

I need my car tuned as well, i think.

lol yes your car would need a tune, i would think.

[Double_0_Rusty]

It was probably never tuned after the cam was put in? Idk. Oh well, maybe Mark or Ryan can do it to it..lol

[dynoman14]

No problem with Automatics, we do not descriminate...we even run Mustangs and Corvettes when the owners take them out from under the car covers...

Did I say that out loud??? I guess running the dyno til 2a.m. yesterday has wobbled my sense of political correctness & hearing.

We picked up a Crate Engine chevy late-model almost 300ft.lbs from 2500-5000rpm and 51 hp from 5000-6200. About 1 1/2 days on the dyno.

Let's see customer bought a new Braswell Carb for $2600 was +5hp, spent 11 hours on the dyno @$200hr = 2200 and got +50hp...

Which was cheaper ???

[redrumracer]

thanks for the info Mark and updated the list as well

[Elbow]

I might stop by, anything against me tuning my ecu between pulls?

[dynoman14]

Simon,
Without sounding like an a$$hole I am going to preach a little about octane mis-information. Not at you but for all who care to take the healing...Engine fuel selection is really a function of piston speed and engine power level expected.

I like to sell it, but in most cases it hurts power output if you are doing real world acceleration testing. If I sell something to my circle track customers that slows their car down, I am not very popular guy; even if it supposed to make more power.

I test everything!!!

What does this mean??? Well there are 50 different race fuels that are 110 octane, why do some make more power and some make way more power???

You have to have the expertise to match the burn rate of the fuel to the engine you are testing. You have to test them on the engine / chassis dyno to determine what is best for your car. Diesel has an motor octane rating of 120+ but you would not run it in your gas engine. In an 18:1 Cat it will make 2000ft/#.

What you will find is that lower octane fuel will have the greatest capacity for BTU production ( Energy = Power ) when burned.

Long story short, to make the most power you have to match the fuel with the lowest octane you engine can stand, while still maintaing the proper burn rate to accomodate your piston speed and you will have the best fuel for your engine.

More on this topic will be in some upcoming Tech articles I will be writing for Nissan Sport Mag, along with a Nissan engine build for a drift / drag / road race application.

I have a good guess what will run in most engines and we can test from there.

THX,
DM14

[Elbow]

My old Civic would run on leaded 120+ octane lol

I don't want any for the Miata I was just seeing what you all had.

[santacruz77]

i dunno when i can come. it will prolly be later in the day if any im completly empty on gas and only have 5 bucks. which i have to put it in the tank..... ahh another weekend with no job and being broke.

but if i dont come im still gonna go up there some time to check it out. or maybe we can have another meet there.

[dynoman14]

I have; M1-HPD ( methanol ), C-11 ( 108 ), C-12HPD/o2 ( 112+ ), C-16 ( 117 ), C-16HPD/o2( 120+), Q-16/o2 ( 120+).

I will also be marketing HPD Import and Import+ as soon as I get the last of my chemicals in.

We can build you any fuel profile that you want and max the power for any application.

[dynoman14]

Santacruz,
I was going to make you an offer of running for 1/2 if you showed up in a Bikini top and let me post the pic to the PCD web-site...

Hell, I don't know if $5 worth will roll that 240 to the shop, tell you what; show up at 9am and I'll give you a job for the day, since you know everybody you can help pimp the deal, serve up some food, help direct some people, put up the chrome dance pole...etc.

Check your PM for the offer...

How far is it from lawrenceville gwinnett? I want to go, but my axel has been acting up.
