Hot!! Dang hot!! Waiting for the rains to start. The D ain't liking this heat either. Still pinging (although not as badly) after going down to Champion RCLY9 plugs, replacing the PCV valve, and the malfunctioning rear O2 sensor. I'm thinking about having my spare PCM sent back to B&G if it can be refurbished to have the 408 flash renewed, but with the stock timing map if he can do that. Have a possible trip coming up to Laos, Vietnam and Cambodia in August that I dearly want to make, if I can get this thing to run okay in the heat.

You might try this old trick. It was used on the Mustang in WWII. Water injection. It does several things. It cools, cleans and increases power all at the same time. The water helped remove detonation in the engine, cleaned the cylinders and heads (water expands something like 57 times when heated and blows off the carbon that tends to build up and due to it's expansion creates more power.I still read about water injector kits available once in a while.

 

Water injection kit are around. I've seen them used in conjunction with superchargers.

 

Take a read of this thread on water injection on a D. At first it sounded great, whoever his long term results were just so so.

Maybe instead of water Dave? you could inject some Varinthip?

Back when the ricers were going to turbo's on everything and suffering from major turbo lag, BMW had a turbo kit from I believe either Krauser or Luftmeister that included water injection. The Beemer was the only turboed bike tested that never had turbo lag. You'd have to refill the bottle everytime you stopped for gas, depending on how hard you hit the turbo. No pinging, period.

Since that's the major concern(pinging) here, I think it'd be worth a try.

 

Actually you'd get better results injecting alcohol than water?

Think about cost. Specially where all you have to do is melt snow, the cost of water is much less than alcohol. You're not running a bottle the size of a radiator recovery bottle.

 

Mike I'm not talking about cost but efficacy and POWER. In the late 60s and 70s the Le Mans cars in Europe (especially the Porsches 908s and 957s) all injected alcohol as the weight of water vs the advantage you got from increased compression negated any benefit. Whilst alcohol would provide a lot more thermic calories and compression for the equivalent weight.

Dave's 408 has plenty of power? I've seen it. It's the pinging he'd like to get rid of. Water may do it? maybe.

In thyat case, open the hood and wait for the rain :cheesy: :cheesy: :cheesy: J/K

Ummm for the driver or the D? Both?? :clap:

 

I have already discovered that the more alcohol I inject into the driver, the less noticeable the pinging gets. Either that or the driver don't give a rat's a-- after a certain point. :twisted: The D also gains a lot more power, sounds better, and the driver gets a lot better looking.
