Looks very promising. Don't have to mess with the exhaust or install and
plumb an intercooler. Sure supercharger is parasitic but looks like an
effective way to add hp and torque without detrimental effects on MPG. I
think my REPU wants one!

What are the CONS of running a supercharger? Does anyone know if the Holley
Avenger comes pre-jetted for your application?

Boost: 12 lbs.

 

Don't forget the need of an Dist, and the complete inability to pass any emissions test

 

and any boost over 6lbs is really going to need a intercooler

 

Ewwww- hope you don't plan to operate it on Cali highways, Drive- I on the other hand live in FL, and there are NO RESTRICTIONS!!!! mmmmmooooaaaaaahaahahahahahah!!!!!!

 

I want one. I've been saving some money, and hopefully I'll get one this august. Icemark, if dist. stands for distributor, they said you don't need one, you can keep the stock set up.

 

Ladies and gentlemen, in CAlifornia you don't need to smog any vechile 30 years or older. Thus I'm considering supercharging my 74 REPU which is smog exempt.

No prob with dizzy, I use and electronic one from 1st gen.

Anyone use a supercharger on their Rx7? Looking for good first hand input.

 

Um what RX-7 is 30 years old?

 

1974 Mazda Rotary Engine Pick UP. See my sig!

 

So you are droping the s/c in the REPU?

 

He said that more than once.

 

i want one, since in Vermont emission dont matter much over 15 years!!

**** my buddy inspected mine and only made sure the light and stuff worked thats it, HEHEHE!!! =p

 

Here In Ontario, we are exempted of emissions when the car Is over 20yrs old.

 

Anyone here supercharged? Still looking for personal experience with it.

Thanks,

 

In my time here I've only seen one or two people take this path. This is probably because it's cheaper just to go and buy the EFI Turbo engine that was designed for these cars.

I have the Atkins 5" bought it before the 7" and the 9" where even made. Best MOD I have done to my car and I do not need any computers or intercoolers. Yes you can make more power with a turbo but I personally like the bottom end torque I never had before. Any questions please ask oh by the way 72 RX2 13B.

 

here's a site where a guy has a write-up about his SC set-up:

You can do that with a turbo too, but they'll make either choice much better.
