Sounds like the power valve is roasted, have you ever sneezed the squeeze back through the carb ?

 

+1 on the power valve. Sounds just like the problem I had when mine took a shit

 

hell yea it did!! is this what caused nitrous fart and any idea on that et

 

Something else most likely caused your backfire (to much timing ? ) but when it did this it most likely took out your power valve. Make sure when you get a new one you get the sane size, it's stamped on it.

Not sure what you are asking about the et ?

 

thanks scott ok im changing the power vale tomorrow

this is my et question

2nd run with nitrous shot rt 5.38 60ft 1.8 then i had to cut it off and hit the brakes popped fire thru the k&n so that run was 10.4 at 40 mph what time would i had ran if it wouldnt caught fire i cut it off at about the 100 ft mark thanks in advance gator

 

There is really no way to tell what the ET would have been. I did not see you out there wednesday night did you make it out???. Be carefull in here bother there are alot of Carb Nazi's around these parts.....

 

no still the trailer issue call you in a few carb nazi lol......

 

what's that? sounds complicated, don't think I have/need one...

 

It is that part that gets Mustangs into single digit e.t.'s, so I can understand your confusion.
