1. What size supercharger is used in this kit? Back
The seven inch supercharger is used in this EFI kit.  
   
   
2. Is the 176 horsepower with stock injectors and ecu? Back
Yes  
   
   
3. To get more than 176 horsepower, what injectors are required? What ECU changes? Back
We have not yet tested our system with a new computer, so we dont have any numbers. We have run the car with larger injectors and noticed an increase in horsepower but again we didnt dyno it with larger injectors.  
   
   
4. Is a new fuel pump needed? Back
A new fuel pump is not required however an aftermarket fuel pump would increase performance.  
   
   
5. Will engine durability be affected at the 176hp level? Back
Engine durability and life should not be affected under normal driving conditions.  
   
   
6. Will the stock clutch and transmission work? Will a turbo tranny be needed? Back
It depends on your application. We used a stock tranny, clutch and rear end on ours and it worked great. Then we decided to race it at the track and drive it real hard so we upgraded to a turbo tranny.  
   
   
7. Is 92 octane pump gas needed? Back
Yes it is.  
   
   
8. Why isn't an intercooler needed? Back
Port injection cools the air as it enters the chamber.  
   
   
9. What are the "bugs" that are being worked on? Back
Getting a smoother idle.  
   
   
10. What happens to the 6 ports and actuators? Is a new lower manifold used? Back
The actuators are removed, and yes a new lower manifold is used.  
   
   
11. What is the max boost with stock injectors? Back
Around 6-8psi.  
   
   
12. What is the max boost with larger injectors? Back
Around 8-11psi.  
   
   
13. Why should i buy this kit? Wouldnt a TII engine and driveline swap give me the same performance and cost? Back

You wouldn't make the same horse power at full rpm range and a supercharger is cheaper. In order to make a turbo run on a N/A car you would need the following:

Turbo Long Block

800.00 - 1000.00 (junkyard used)
Series 4-5 Turbo 250.00 - 300.00 (used)
Turbo ECU & Harness 450.00 - 600.00 (used)
Intercooler 100.00 - 200.00 (used)
Turbo Exhaust 789.00 RB (new)
Turbo Manifold 50.00 (used)
Flywheel & Clutch 485.00 (new)
Transmission 500.00 (used)
Driveline 350.00 (custom new)
   
Total 3774.00 - 4274.00
   

Please note that all the parts listed above for the turbo application are at a used price, whereas our Supercharger Kit would have all new parts and our supercharger has a warranty.

 
   
   
14. Why does my motor ping or spark knock after installing the EFI supercharger system? Back

The is happening because you may not getting enough fuel or the fuel octane is too low, also you may have your timing advanced to far.

 
   
   
15. What is the correct idle speed? Back

Because of the added air volume it needs to idle between 1200 and 1500 rpm.

 
   
   
16. What is the optimal fuel enrichment setting? Back

We suggest that you add an air fuel meter to your vehicle. For carbureted and fuel injection forced inductions sytems 13.5 is optimal. Running your system slightly richer will work as well. Under acceleration the meter will show lean and then even out. So running the meter slightly above the focal point will work just fine.

 
   
   
17. What is wrong with my idle? Back

Take a look here to find out how to install a TPS LED diagnostic in order to adjust your tps. It is also possible that you may need to advance your timing slightly.

 
   
   
18. What size pulley comes with the EFI supercharger kit? Back

The EFI supercharger kit comes with a -7 pulley.
