I met up with Rotarystylez at the Monster Mash car show this past weekend. He has a Mazdaspeed grounding kit, and a few other nice mods, you can ask him about. One mod that I was very impressed to see was a Apexi turbo timer, that he picked up upon delivery from a dealership on Long Island! You can ask him all of the questions because I don't know if he has a secrecy agreement with the person who hooked him up. Anyway here is a couple of pictures of his 8 and the turbo timer. Wish I had one just so I didn't need to sit in the car and wait for it to cool down after driving hard.

 

why i ask why....

 

he needs a turbo to time now....

 

Well, when I originally bought my 8 the dealer suggested that after driving the car hard or even when just driving the car for a short period of time, that to shut the 8 down the correct way is to let it sit for 1 minute or so, especially after running it hard. So I would want that so I didn't need to sit in the car for the extra minute or so.

And yes, it does need a turbo to time now.

 

All rotaries benefit from proper cool down whether force fed or not.

 

That's why I thought it was a nice little extra to have. I've done extensive reading on rotary engines since I bought the car last November and cooling the engine properly is a good idea. Also a smart way to go on the salesmans part.

 

apart from turbo timing, it also shows you the voltage, O2 reading and something else i cant remember. got one 4 years for my other piston powered, turbocharged mazda :D

 

Here's a question....A turbo timer's primary purpose is to continue running the engine to continue cycling the fluids to prevent hot areas immediately after shutdown...

Wouldn't it be a better idea to get an electric water pump, which continues running after the vehicles been shut off, for say 45-60 seconds? Then you wouldn't have the temperature of combustion effecting any particular aspect.

I realize the turbo timer is primarily to continue cycling the oil through the turbo, but in this case, there is no turbo.

Running an electric water pump would not only enhance the cooling down process, but it would also eliminate a parasitic drain off the crank....freeing up more power.

I realize its not as "cool" as a turbo timer, but I think it might be useful none the less. On the Mazda 6 moving to one eliminates an entire belt/pulley system, as well as eliminating a rather massive cam pulley.

 

I was just thinking about a TT the other day. It would certainly help with the times that you need to simply back the car up or give it to a valet. It ensures that you never don't (yes I know it is a double negative) let it warm up properly i.e. no flooding.

Interesting.

 

These things are a waste of money even on most turbo cars. Just don't drive like an idiot all the way into your parking space and you're fine. Of course, if you really like having gadgets everywhere and the extra cash is weighing you down, feel free.

Not one person i kno who has a turbo says it serves no purpose, so i dont kno where your gettin ur info from, But anywayz, wheather or not u drive hard or not into ur driveway your still gonna have the chance of hot areas with the TT You want have to worry your little head off

 

By the way My Baby's Gettin ready for a nice FD TT Coversion Hopefully Gettin some nice space in RX TUNER after its all Done with. All Work will be done By J&R Performence (Smokin Joe Racing) Best Guyz on the island to work on your Rotary. Smokinjoeracing.net

 

In most modern turbo cars it's useless. There now you know someone with a turbo car that thinks they can be useless, and I can introduce you to about 20k others if you want to take a stroll over to the WRX boards.

I forgot guyz we have WRX's ...OOOPS MY BAD! do we have rotary engines?, your info means neiente to me. Get me some info on turbo timers and the purpose they server on [B]ROTARYS

 

You are correct about modern turbos, although rotary engines need to start and be shut down properly. I may be wrong, I don't know everything, but from what I have read, this is the case in rotary engines. Any engine in the issue of heat shouldn't just be shut down cold. The engine, any engine, heats up and expands slightly, especially when running the car hard. I feel and because I'm obsessive, that giving my engine a minute to cool just a little before I shut it down is better for it, and it's longevity.

 

You said turbo cars and so did Bureau when you tried to tell him his correct statement was not true, no mention of ROTARY turbo cars. Whether or not a TT will be useful on an N/A rotary is up for you guys to decide. Yes it may be wise to cool a rotary down for a bit after hard driving, but it cools down slowly after you turn it off regardless if you idle for 60 seconds or not. Go feel your engine an hour after you've been driving, it's still pretty damn warm.

 

C'mon IkeWRX, you know the laws of thermodynamics are different for rotaries

RoTaryStYleZ, I owned a twin-turbo FD prior to my RX-8, and before that an '87 TII. If that still doesn't count, why don't you check out the RX-7 forum in the 3rd gen section and ask what the general consensus is over there regarding turbo timers on rotaries.
