im getting a rebuilt ported motor with turbo 2 rotors for my future supercharging project. i have a bonez intake and racing beat complete exhuast(headers, presilencer, and cat-back). i dropped my emissions. i need ideas on other mods to get. any ideas anyone? is the apexi safc a good idea to get? if so is it hard to tune it for maximum power or should i get it dyno tuned? any ideas or opinions are welcomed, i want to make this thing as bad as as i can. ohh yeah, i wont have the supercharger for a few months, but ill be getting the motor in the next month hopefully, so ill be running around with the low compression. thanks everyone for any opinion or ideas.

 

I would suggest looking into the Eaton superchargers found on mid 90s cars made by Ford and GM. The cars that come to mind are the Thunderbird SC, the Bonneville SSEi, and the Buick Riviera Supercharged... also the Grand Prix GTP. The three GM cars contain the Eaton M62 or the M90, depending on year, and the Ford car has the M90 for the entire run, I believe.

 

There is a huge supercharging topic already started. I would bet it contains most of this information.

If you really want to make this thing "as bad as you can" you'll need to throw this out and get an exhaust suitable for forced induction (i.e. bigger).
I'd consider it an absolute minimum, as well as an upgraded pump. You'll need upgraded injectors if you plan on more than 240-250hp. Again, making this thing "as bad as you can" would require a proper programmable EMS rather than just an interceptor, and an intercooler should not be considered an optional extra.
Unless you have the necessary experience, knowledge and equipment, trying to tune for maximum power will most likely result in a dead engine. Take it to a dyno and have it professionally tuned.

 

ill be getting a lightened flywheel and centerforce clutch at the same time my engine will be going in. should the injector size be changed on the secondary side when the engine goes in considering that it is ported? i do have a walbro fuel pump and plan on getting the haltech standalone once i get the supercharger, but was thinking of just getting the apexi safc for now to tune the enging a little bit. should i get bigger injectors for the secondary side only or for the primary and secondary side? also what size injector would be suitable and from what year rx7 could i find it on? by the way the car is a 1986 rx7.

 

Unless you are some severe porting done (ie. full bridge or peripheral), your stock injectors are fine.

S-AFC is a great idea on EVERY FC (which doesn't already have an aftermarket EMS system).

 

Atkins was at Moroso this past weekend. they had a Supercharger for the 6 port. 275 dyno hp 28mpg. with a small carb. bigger carb more HP.

 

anyone have an idea how much the camden 7 inch displaces?

 

hey Aaron, you just said that with a supercharger he won't need bigger injectors than stock N/A right? I didn't see you chime in on that on the other thread.

 

You won't need them until the supercharger goes on, and even then only if you're making more than ~250fwhp. NA secondary injectors are easily swapped without having to pull the UIM like Turbos, so just wait until you need them.

 

i want to hopefully get to the 300-350hp range or more to the wheels running the camden fuel injection kit at 11.5psi with the mods listed, do you think it is possible? with that in mind, what size injectors should i get?
FYI: im getting a large street port on the motor.

 

350hp needs about 2600cc/min "worth" of injectors. A 550/720 combo is close.
