Dave, you do realize that anybody will be able to improve the current tune on that car, now that the car has clutch that won't slip, right?

Smoked is already signed up for another dyno day in STL since he's gotten his car sorted out mechanically.

That said, you should take up Shiv's offer for a fun back to back tuning challenge! Meeting each other in person (on your turf no less) could go a long way in restoring vendor relations and helping get the drama off this board.

With the customer being willing to participate, it could be a really interesting day!

 

This is Bruce Hamilton's GAS FAQ, probably the *only* thing on the net about gasoline you can trust!

These are the numbers everybody quotes. They're absolutely correct and absolutely meaningless. The conditions of the Project 45 work have nothing to do with a modern, turbo engine. In practice the blending octane number of toluene used with premium pump gas is about 101.

Dave

 

I agree. The conditions within a modern turbo engine are sooo different. (Even from engine to engine!) RON is ridiculously far from reality ... MON numbers are a bit closer ... but both could be a lot better. (I just wanted to give people an idea.)

In either case, I just meant to say that there are other chemicals, which are often added in higher concentrations than TEL, which might affect the burn, and stoichiometric, rates more intensely.

It might be worth noting, for some people, that the difference between RON and MON has a lot to do with intake and coolant temps. IE: keep the coolant and intake temps down and high-sensitivity fuels may see a disproportionate increase in detonation threshold. It's usefull knowledge, though application is tricky.

Good stuff.

 

Smokedmustang you just have to get your issues lined out and your car will be making good power and be in the 11's. I watched you run on Tuesday and you are doing very well at driving for being so new to drag racing, 1.7 60's are great for your first few times. You dont need to remove anything from your car you are doing fine even with the big ole' wing.

Leaded gas ruining your spark plugs is just part of it, if you want to go fast you wear parts out. Plugs cost $6 to replace and about 5 minutes of my time, I dont see what the big deal is there.

Buschur/Al you guys did a great job with David's MR, I got a chance to check it out Tuesday also. We will hopefully be lining up together soon.

 

Shiv in Daves dyno room I gotta drive down for that one.

 

Wow

 

I'd consider getting a plan ticket for this...

It's certainly easy to test that very same day. After I tune the pump gas map we can dump in leaded race gas and see what happens to power. Then I can tune the race gas map. And smokedmustang can compare all the results on the road and on the dyno. Sound good?

Ditto, I'd drive out for it....

 

I think that certain vendors seem to want to have dyno tuning contests to see who can make the most power on a mildly modified customer car as some kind of publicity stunt.

To me the concept of such a "contest" is ridiculous becuase in a customer's car of course a professional tuner is NOT trying to reach the MAX possible whp output (which is actually very easy to accomplish). Rather, a very good tuner is capaable of reaching a good balance between smoothness, reliability, power delivery and ultimate power.

EVERY car I hand off to a customer is intentionally DETUNED from the theoretical max power points.

The art of tuning, as far as I am concerened, is in the skill of knowing how far the car must be detuned and in creating a tune which is repeatable and reliable under a wide range of real world conditions after the car leaves the dyno.

These kind of factors are hard to quantify and judge.

It seems like a contest like this would amount to who could squeeze out the highest dyno figure on a custiomer's engine which is totally irelevant - IMHO.

It will be interesting to see how Mr. Buschur responds to this silly chalenge.

With at least 2 900 whp evos currently sitting in his facility I think Mr. Buschur is ready to do real battle - not just play games.

Al

 

I will not this one go south...

-Zeus-

 

Sorry Zeus...

 

Al, I don't think that should be the point... as you well know, peak numbers are meaningless... in this instance everything from daily drivability to fuel economy could come into play. Personally, I'd like to see this happen just so the guys could get in the same room and find out that each other is not really THAT bad. I was pleasantly surprised at my own personal meeting with Shiv... some day I'll get way up north and shake David's hand too.

 

No problem... this one could go real bad... or real good. I prefer the latter
I don't expect anyone to sit around and (try to) sing kumbyah (sp?), but it can be constructive.

 

I did one quick search for the words "Shiv, Vishnu, Contest" and post made by user "Dynoflash" and this is what I found...
