A brief description and just looking for opinions!

I am Comptech Supercharged w/ cooler w/ 7 psi pulley stock injectors running somewhere in the 10.5 to 11 A/F , I just installed a T1r test pipe w the mechanical 02 sensor mod (which works perfect by the way) No Cel and between 3rd and 4th under acceleration I get a huge backfire between shifts with a very cool fireball I am about to install an EMS and 550 injectors but was wondering if I may call on some more experienced owners with their thoughts or concerns - the car runs great and I believe I am running a bit rich at the moment - I like the idea of having my very own Roman Candle but want to be safe until it gets tuned in about a month or so!
Thanks for reading!!!

 

 

Yes, it would appear that you are running very rich and in doing so, without a cat present to act as a "flame arrester", I guess the burning exhaust gases are simply going out the tail pipe.

 

I miss Shooting Flames , I need Boost again

 

Thanks for the replies! I heard the POP before but without the cat they are much louder and now I have the fireball - I was concerned but the kid in me thought it was very cool and hope to get it on video I am waiting on my AEM wideband with display as we speak just to be sure I am safe with my A/F until the ems is installed and tuned ! Thanks again for the replies.

 

btw how did you see the fireball? in your rear view mirror?

it must have been very big if it visible in your rear mirror!

 

ya, I was wondering the same thing

 

My roomate VeilsideAP1 was behind me as we were merging on the expressway and he called me on my cell right after it happened and he was very excited and I was concerned - It happens everytime I speed shift through the gears - it is very loud
