what implications would using a boost controller and having both turbos run at once have ? how do you turn them back to normal boost sequential ? will the air/fuel ratio be altered by the controller itself ? what psi would they both run on ?

just inquiries i have since I am considering a car that has this set up, wondering how safe it is.

thanks for the help,

the boost controller can not tell the turbos to run as one, you have to do a non-sequential job on the turbos to do that. You have a bit of research to do I think.

 

If the car is converted to full non-sequential then the blitz boost controller or any boost controller will work. The fuel ratio will be okay as you will get full boost after the secondary fuel injectors open. You can run them at 14.7 psi max for full efficency.

oops, did not see the last post.

how prone to turbo/ engine deterioration is this set up compared to the stock sequential ? i understand that if both are running at 14 psi it will have a dramatic boost in power, but will it be a constant pull through redline with no hesitation ?

and finally, is this set up more reliable if the car will be used for a daily drive ?

thanks guys, this information will be used in purchasing a car.

Uhhh.. WHAT?
Full Efficiency huh? nothing efficient about running stock twins, stock intercooler, and stock fuel system at 14.7psi!

p.s. your boost controller will work fine. Just connect it properly.

 

What I meant to say is that if you have all of the nessary supporting mods you can run them up to 14.7 psi.

The stock fuel system WILL NOT support 14.7 psi of boost. Do some research. We need to know what other mods the car has. You should never run more than 10psi on the stock ECU. If I where you I would check out https://www.rx7club.com/forum/showth...threadid=68640 and go through the sites mentioned. They have a lot of good information...

 

Actually the stock fuel WILL support upto 15 PSI.
I did it for about six months, and I wasn't babying the car.
I would definitely tell you that its IS NOT a good idea though.

 

s-the,

Boost controllers do not effect the a/f artio.
A boost controller simply allows you to vent boost at a level you choose.
Most would recomend not running higher than 13psi on your stock fuel set up.
You want to run more fuel if your going to run over 12-13psi. If you dont just be informed that you can defiinitely blow your apex seals.
I would not waste your cash on an expensive boost controller if you are using the stock twins.
You would be overdoing it.
Anything under say 20 PSI you could do just fine one manual gated boost controller.
www.turbosmart.com.au offers some nice reasonably priced units.

Non sequential puts no extra strain on the system. It actually makes things safer being that you will eliminate any boost spikes when the secondary comes online at 4500 rpm.

Get a turbosmart controller and run no more than 12 psi till you get more fuel.

Good luck,
