hey i just started to spray my car and have a CF 100 shot wet i didnt pull any timing and i have tr6s but havent put them in yet i have tr5s in now. 2 things first when i flip the switch the nitrous dosent instantly engadge and i am at WOT and some times it doesent feel like its on,and also when it does kick in (wow I love it) when the car gets above 5k it pops or cuts out is this due to my plugs.before i installed the lines i checked the noid,relay,WOT switch and it was all working properly. i have even checked it with the lines hooked up and held the fuel line to a rag and the nos line in the air and it worked properly.

on another note i sprayed on a c6 zo6 and ran dead even till we hit 50-60 the nitrous started cutting in and out .

 

From what I have heard when this happens you are running lean.

 

Same thing happend on my mustang. It was lack of fuel pressure for me but I'm guessing it's your plugs. Try a little smaller gap and see what happens.

 

change the plugs to tr6's before you blow the motor you may have a damaged or melted plug

 

ya im gonna change the plugs tonight. is it a must to retard timming also,and will retarding timing make it faster when i spray.

 

as long as you have stock timing you should be fine with a 100 shot and tr6's and retarding the timing is not going to make you faster

 

ok put the tr6s in and it works sooooo much better and hits much harder. thanks sprydncamd ta, o ya what aboutr a 150 shot should i retard timing,or should i not even do a 150 shot on the stock fuel pump

 

i would upgrade to a racetronix fuel pump kit and then you should be fine with out retarding timing but i always would rather be safe then sorry. if it were me id make a fuel pump my next mod

what did the tr55's look like

 

whats the difference with the racetronics kit and aposed to just bying a walbro pump. and the plugs acctually looked fine they the have some black carbon from before nitrous and i the 90 degree piece on the tip there was some white powder look is that normal.

 

The Racetronix kits are a factory replacement item, so they do retain all of the factories fuel system functionally. The plain jane Walbro pumps are not, you'll have to do some modifying of the fuel system to get them to work. The Racetronix systems are also plug and play.
