I can get into the members forum now but I can't get to my PM's????? Help me out Neff.

 

Hey Guys,

Tom let me know about this thread and I guess I will give my 2 cents on this. take it for what you will. I have only partially read some of the issues and apologize for missing things.

The last time y'all were here in May, everyone got a minimum of 2 runs and most opted for 3 as the weather was quite a bit better back at that timeframe and much better heatwise for the NA guys. The longest period of time for doing all three runs was 4-5 minutes from going back through my records. An example is Todd's run 1 at 8:09:24 and the third run at 818 so a span of less then 4 minutes between runs. No one mentioned a time between run issue as they were happy with the runs. Now that the dyno numbers do not agree with what you think they should, there is a complaint of the time between runs. I am more then willing to give some time between runs if asked, just need to make the request.

Of course it rolls on from there. Though it was hot in May, it was in fact 15+ degrees cooler in the morning then as well as a much better barometer and much less humidity. The barometer and humidity play a bigger roll on power then outside air temperature. The less efficient forced induction cars are worse. The DynoJet software does compensate to a point, but is not 100% accurate. Also since, from what I gather, CP uses a Dynapack (?) and then calculates to a DynoJet number, too much room for error. It could at least give an educated guess, but not written in stone.

As far as the lean cars, there was not any knock heard at anytime otherwise the runs would have been aborted. When Ians car was run and found to be lean, some said there was an issue with the A/F on the dyno, We did another run to verify and again no knock, but lean and verified. On Jasons car with the Vortech, I watched the A/f in the beginning which was fine, but as I was watching the tach she leaned gradually, but again no knock was heard. My bad if you want someone to point a finger at. If anyone has anything they want to discuss they can come and do it here in person. I am reasonable, but internet chit chat does nothing for me. We di help with Matts nitrous issue and do a 3rd run so he could test the fuel side of his nitrosu system.

In the end, if there is an issue, call me personally or come on down. If you want something during a dyno day, just ask. But if you ask about the lower HP numbers, all I can tell you is that the internal software does the calculation, not us. Like Tom said, we redyno'd the Mustang and was within 1% of the runs back in May. Does this matter, probably not, but we did that to see if maybe there was a discrepencey that altered your results. If we did not care I would not have checked. dyno numbers are just that, numbers and most guys understand that. If you need to use dyno numbers as Viagra, there will be times disappointment will come along.

Again, take this for what it is worth. There will be no refunds, but since Todd seems to be the chief here, bring your car by and we will do 2 runs back to back, then have a 15 minute cool down, do a third run and see what you get. From there we can compare to this past weekend for a better understanding. If you take me up on this, let me know soon so we will hopefully have close to the same conditions. Then we can have a proper talk. No jabs needed here BTW.

Thanks.

Thanks for the nice gesture Mike. My car's seen 29 runs over a 3 day period. I think that will have to hold me over for now.

 

Thanks for chiming in Mike...I really do appreciate your concern. But...I had no idea about the "leaning" my car was doing until after the runs. I think the other Jason feels the same way. I could care less about the hp numbers. I just want to make sure my engine holds and runnign 13 a/f during peak torque isn't what I want to see.

This internet "chit chat" is our club forum and we can discuss anything we want. Nothing was behind your back as this is a public forum and you are more than welcome to read. But when your shop (through Tom) says its the customer who should tune it prior to dynoing, then I have a problem b/c you have a responsibility to watch the data as the run is going on. It's you with the "abort" button, not the customer. Thats where my problem lays. Not the final hp numbers.

 

We appreciate you coming on the forum and posting.. we know you are running a business and are glad to see you take the time.

Whether you hear knock or not, you can still cause unecessary wear on a FI motor correct?

Internet chit-chat is much easier then making 2 hour drives back and forth from Jacksonville to discuss something with you that ultimately will end with the same result. What is done is done, I am just expressing my feelings, concerns and opinions with what went on this weekend.

 

g8tor20,

I had no idea either as we were not checking runs until after they were done. If this is Jason with the Vortech car, then it actually had a good A/F up to the point I went back to looking into the car and checking the tach. Could be some hindsight here, but that does no one any good but to gather info to use the next go round. I was under the impression that all the Vortech cars were just done and tuned and figuring they should be fine. Again since it looked good initially and had no signs of detonation, well we could go on forever. Also usually there are tell tale signs at the tailpipe of an issue. Like I said previously, my bad and at least nothing bad happened.

One side note, when we do a supercharger package here, we stress the importance of gauges to monitor boost, fuel pressure and air/fuel, no matter how simple it is. Not trying to be a salesman on this at all, but if you would like I us to see what we can do about the tune or if there is a pressure issue, we will do what we can. Once we get the handle on the G35 in the shop it should be no big deal. I guess whay I am saying is that for the guys that had tuning issues and would like some help, we would not mind working with the car to get them right. I know most can handle their own stuff.

turbomaxima,

Correct to a point, but usually there is some sign of knock, even non-audible. When talking low boost levels minimal chance, but continued hammering over time will take its toll. Not sure how long Jasons car has been together, how many times been run hard in that condition previously or how long the A/F has been doing this and that would have a lot in a failure also. No matter what I am responsible while running my dyno.

I didn't mean to trivialize the internet chit-chat, as I typed too much and get tired. Old man-itis. But in the end I prefer a call or even someone to say something when things happen to be resolved properly. It can get too gossipy and angry when typing to a screen. Sometimes too easy. Hopefully all things will work out.

Todd,

No problem and the offer stands. Just let me know.

Thanks for standing up on this one Mike. Classy reply.

 

+1. Thanks for coming on the board.

 

Thanks for all the replies Mike. Not many people would have the courage to answer back and do so in a professional manner. it says a lot about you.
