well now im in a debate.. im looking at 2 different kits.. one will inject off of boost pressure and the other taps off of the maf sensor. which one is the better of the two?

 

it doesnt matter i have mine set up with the map sensor but i am going to change it to the boost line
if you some how get a bad connection with the map sensor and you dont spray meth say bye to your motor

 

hmm ok.. yeah i've been leaning more towards the boost pressure one. seems more reliable, and for my application i want to start injecting meth at a certain boost pressure. also seems easier as well.

 

if you dont spray your motor will pull timing. shouldnt be that much of a problem.

 

is has nothing to do with timing meth adds unmonitored gas and when you spay you need to take fuel away. so if you are not spraying your car goes really lean and blows up

 

i dont know if this is correct but when your car pulls timing doesnt it also need less fuel at that point, putting you back in to a safer range when the meth fails to spray? i could be dead wrong on this.

 

ya it will start knocking. the car will automatically put it in safe range. thats what the knock sensors are for.

 

well if you are like me and run a good amount a meth you will do damage to your motor if it doesnt spary but if you are not spaying that much you should be fine

 

ive only got a 3ghp nozzle. i didnt really wanna go overboard.

 

i am running a 7 gph and it runs great i am think of going bigger and a 2.6

 

u think a 5ghp would be ok with my 2.8?

 

i talked with the alcohol injection guys yesterday and they said a 7gph nozzle would be fine for me.

 

yeah you could go with a 7 gph if you wanted you just need to tune for it

 

i have a 10, and one want a 10?

 

well how much of a difference could a 5 make...

 

it depends. how hot does your car get after a 3rd gear pull and how uch timing are you running on your set up now

 

24* and it only got to about 30* hotter than ambient air temp.

it was about 75 out that day.

 

i dont know how much it would really be able to help you but you could pulley down and go with some more meth and make some more power

 

What do your inlet air temps look like? any kr? It honesty can make a pretty good diffence going from a 3 to a 5

you can try bigger. imo if you go any bigger more than likely you are going to need to increase you % of meth in the mix to make a 10gph nozzle work.

 

i use 75% meth and 25% water
i think i am going to keep my 7gph and add a 3gph after the supercharger
