Ive done a lot of reading but havent found much so i have to ask. Is there a site to help determine do i need to upgrade injectors. I am working on the vehicle in my sig and have issues with power curve and feel. I have HP tuners and am still learning to use, but Ive read online my oem injectors are rated for 300-330 horsepower TRUE?/NOT TRUE?. If i add the numbers on what i have done i should be maxing out the injectors. Ive read #81 marine injectors are a good upgrade but i cant find much info for power ratings. Any suggestions or advise on upgrading would be much appreciated.

 

What's your injector duty cycle hitting?

 

Im getting to take it for a ride and log. Ill get back shortly. Sorry should have been more prepared.

 

I ttok it for a short ride and logged. I found it was at 100% duty cycle at full throttle when dumping it from a rolling 25mph.

 

Just don't do like I do and go huge. 8.1 inj or 60# inj should be fine for your app.

 

For your setup I would go with the 8.1 marine injectors. They should be plenty at 43lb I believe. 60's are way to big unless you plan to add boost.

 

I dont have any plans of boost as of right now. It sounds like the 81 marine injectors are the best option. Is there only one style on the market. Or is there a certain type i have to look for. I.E- Ive heard of there being talls and shorts on different types of intake manifolds. I have a stock manifold and stock injectors and rails currently. ANy help with a site to find them would be great. Thanks for the help and Advise.

 

I would look in the classifieds or post up in the WTB section usually you will find some. Good luck

 

The 8.1 injectors are multec 2's which is what you have. That's the injector style, like mentioned I would place a add in the WTB section.

 

Thanks for all the help and advice
