I found this site called:
http://www.electricchargers.com/
They have a charger and chip specific to our car.
I asked them about my 91 RX7 vert non turbo. They told
me that I would gain the following:

Yes, we do have an electric supercharger and performance chip to fit your 1991 RX7 convertible.

You can expect up to 33-34 HP and 22-23 FT/LBS gains on average when using our supercharger and chip.

If you have any other questions, feel free to ask.

Does anyone agree with this I am thinking about buying it to gain more horse power off the line. I already have the Racing Beat Exhaust system. That helped a lot.
I thought that this could be my final step.
Please let me know your thoughts?

 

Stop Posting The Same Thing Over And Over Again! All your posts are for stupid useless wastes of money. PLEASE stop posting in general for at least 6 months. There is nothing you can do with your car at least for the first 6 months, that someone else hasn't already done, documented, or asked and got an answer so far.

Stop it. You have asked like 3 back to back stupid questions.

Sure add 10 of those little fans to your car! You will be a super fast NA 500 HP easy.


Get an oil change, make the car run better. Save your money for maintenance because YOU will break something.

 

Surely you jest. If that kind of power increase could be had for $99.99, every car owner would have one.
Did they also promiss better fuel mileage?

 

lol wow...eletric chargers....seriously, come one...THINK MAN!

 

ya know what, ya buy it so it can be the final step. Then maybe you will stop posting.

 

Again –
These things are next to useless.
At most 1 PSI of boost at low revs when on, and a big restriction when off.
The VDI on your S5 give more than that.

Most of their exaggerated power gain claims come from the K&N.
