CHECK THIS OUT...AWD MD in and running at Buschur Racing.
Well everyone it has been a long week and there is still a week left. 13th Annual DSM/EVO Shootout that we put on every year is this weekend. August 13th is a car show/open house/dyno competition at our shop. August 14th is the race at Norwalk Raceway Park.
We finally got our dyno last week. Had it installed without any real major problems. Fits into the new building like a glove, exactly what I had in mind. Even the 3 guys from Mustang Dyno that have seen it have been very impressed with the ideas. The new building is going to be super nice. It is basically done on the outside. Floors are done, epoxied them this weekend, grey. Used the speckled chip epoxy with blue, black and white chips. Really nice. We have just the basic electric and air in the building now. All the interior walls are finished yet but will be soon. The building will have a very nice observation room for customer to sit in heated/air conditioned comfort behind a large safety glass window to watch their cars being dyno'd. Stools, tall tables and such. Trying to make it top notch.
Anyway, the trainer from Mustand Dyno (MD) came out on Friday. Got everything hooked up and in. We loaded up my RS and made the first pull. Not sure what I expected but what I got was definetely short of what I wanted.
The dyno comes calibrated from the factory. You have to pick enter your vehicle weight, the horsepower it takes to propel it down the road at 50 mph (listed in a chart you get with the dyno) etc.
I owned a Dynojet for over 5 years. The Dynojet isn't even in the same league as this thing. Sorry to anyone who likes them, but atleast comparing it to the old 2wd model I had, there is no comparison.
This thing comes with a freaking manual that looks more like a dictionary. Very complex tool.
My RS on our 2wd Dynojet made 393 whp and 390 ft lbs of torque on 94 octane on the stock turbo, when it did this it ran 11.7 at 116 mph.
The RS last week ran 11.31 at 120 mph now, being tuned on race gas and our new 20G turbo at 22 psi of boost. To me this means it has increased between 30 and 40 whp from where it was before. This made me think (or dream) that the car would put down atleast 400 whp on the new dyno.
NOT EVEN CLOSE. The first pull I made the car made 330 something. I felt sick. The guy from MD was impressed, I was sick. I tell him, "Dude, that **** ain't right." He says, "What should it be?" I tell him over 400 and explain why I feel that is the case.
I look at the datalog in the EMS. Figure, alright, I got screwed. This is another case where the dyno and street are completely different.......not the case. The datalog was perfect, looked just like the street.
WTF?! I tell the guy lets try it again. Again, 338 or something pitiful.
O.K., I didn't want to do this but I am not happy. I ask him, "Alright, I know there is a way to manipulate those numbers, how do you do it?" He laughs and says, "Just about every guy I install one for wants the same thing." So he attempts to show me some tricks. Well guess what, no matter what we "lie" about in the computer the power stays the same, within 10 whp anyway. He say, "How do you like that?! The car made 348!?" I say, "Look, that number is BS, no way you can convince me a car making 348 whp is going to run 11.31 at 120 mph." There has to be another way to change what the dyno reads. He makes a phone call. Tells me the other parameters are "locked" but he can unlock them and change them. He does it. The power drops. I say, "You went the wrong way with your adjustment, please go the other way." HURRAY!! My car now makes 408 whp! So, now I am even sicker. The last thing I want is to mess with this brand new dyno.
Here is the dilema. As many of you know I have a guy up the street doing the same thing I am. Of course I'm not happy about it. IF any of you were to go to one shop and dyno 408 whp and then came to mine and dyno'd 348 whp I am pretty darn sure that you will not be coming back to me. That is my dilema.
On with the long ass story I am telling. I explain this to the MD trainer. He agrees. I tell him, look for now please put the dyno back to exactly like it is suppose to be. I make another pull 340 whp and we call it a day. It's about 8 pm now.
Next day I come in after not getting any sleep over this ordeal. He meets me for breakfast. I try not to ruin his meal by talking about the dyno.
I go over the dyno set up and operation with a million questions again and he is super nice and explains it all to me....again.
My brother shows up about this time and says he is either putting his EVO on the dyno or going to the track. I tell him get it and load it on the dyno.
Now his car is our Stage 4 with 1650 cc injectors, AEM EMS, our race FMIC, our GT35r kit, our head, our stroker etc. The car has only been tuned by myself on the street.
Now remember, the dyno is exactly like it is suppose to be. NO more games or manipulating it. Daniel, my brother, pulls the car. It sounds freaking amazing. The MD trainer freaks out!! He says, "Holy crap I have never seen a 4 cylinder do anything like that!" I look at the screen and it says 638 whp 585 ft lbs. WOW!
Now I am even more messed up. How does this car make 638 whp, which is what I would expect on our 2wd Dynojet, and mine make 340? Daniel wants more, of course, so I make a few fuel changes and to his and mine amazement the power will not go up. I guess that old ass dyno of mine is better than I thought. I ended up on the last pull adding a couple more degrees of timing just up top and the power rose to 640 even.
Over the weekend I figured it out. It was quite simple actually. I would call my competitor and make a dyno appointment. Pay the $150 for an hour, make 3-4 quick pulls, get dyno sheets with HP/Torque on them with speed/rpm and then go back to the shop. Dyno the car again. Then I would know exactly how much the two dyno's differed.
Well I called first thing this morning and am told I can get in afternoon sometime, get put on hold and then get told, "We don't think it would be a good idea for you to come here and dyno."
I guess that was a smart move on their part......?
I'll get a car in there, watch out guys..........somebody is going to get an appointment there........ooooohhhhhhhh........then dyno at our shop too.........oh my. hahahahaha
Actually there are a few guys coming in from out of state this weekend that have just dyno'd on AWD Dynojets, I am going to dyno them when they get here so I can get an idea of the difference. Saves me $150
More information. After I took my car off the dyno the first night I drove home and did some pulls, exactly like I did on the dyno. I am truly amazed at the accuracy. I guess this is what a real dyno does, simulates road/track conditions. The AFR's were within .2, in other words on the dyno they would be 11.2 on the road they would be 11.4, or in othe points the AFR's would be 11.4 on the dyno and 11.2 on the street. Boost levels at any RPM were within 1 psi. Very nice.
I am really looking forward to getting started tuning with it. I think the results will just be phenominal.
I'll whoop any advertised dyno rates, just give us a call. Also will offer up our shop/grounds for clubs and dyno days, also just give us a call.
If you can make it to the shootout this weekend come down, you won't be disapointed!
