How difficult to build is this?

Just get your self a pocket digital recorder and record some.

Or just search for engine sound clips and burn them to a CD then play it in your car.

I did those little tricks already but I want to have it sync up to my engine rpm. But how???

To have this done from scratch, it will be expensive. All the R&D would have to be independently done.

Why not invest some money, and have your engine built up to have the power and the sound! Then you will have the real thing. Why make a chicken sound like a Turkey!

Or better yet, save your dollars and go out and buy a real good fast car!

What is that movie, Vanishing Point? Dodge Hemi Heads are the best sounding engines of all, in my opinion. I own and drive a 1978 big old long body Dodge van, 318 engine.

It isn't a Hemi Head engine though.Someday, I might check with Wiley Deen and his auto junk yard.He can tell me if he has a Dodge Hemi Head bolt in engine.Even it it needs rebuilt, no problem for me.I have rebuilt some engines before. cuhulin

Exactly.. For the couple of grand you'll spend on getting this device developed and built you could just build an engine.

I suppose you could figure out a way to make a laptop do the same thing, but you'd need programming knowledge and also some way to interface it to your tach.

Put some glass packs on, and one of those exhaust cut out whistles, (sounds lie a steam factory whistle, sort of,see

and a Bull Horn and a Air Horn and a Ahhoooga Horn,,,,,

For funsies, get some Visegip pliers and go aronud and squeeze the tail pipes of cars and trucks flat, almost closed and listen to them whistle. cuhulin

A microprocessor can generate the sound. Tap off the speedometer/tachometer lead to get the engine speed (either count pulses/second or use an RC integrator to average the engine speed and read it with an analog-digital converter (ADC)). Adjust the microprocessor sound output based on the engine speed.

The microprocessor's sound output drives a big amp and some serious weatherproof speakers mounted under the hood and under the rear of the car.

Should be possible to put it all together for less than $1000 in single quantities - much cheaper if you want a thousand or more ;-)
