Who else has had a nitrous backfire?
The K came in BTW.

It didnt hurt my intake just blew the gasket out from between the top and bottom.
Killed the MAF and the lid though.
Dynoed it last night the motor is fine and the speed density tune went smooth BUT ...
I borrowed a 275amp alternator from someone and from what I hear now they dont like high RPM's well I'm shifting at 7400 rpms so needless to say it killed it.
We tried my old alternator with the main power feed to the Direct port wired right to the battery. Well it didnt work
turned on the DP only and the voltage dropped to 8-9 right away.This is REALLY starting to **** me off!
Its going to roll out once we get this gremlin figured out
Anyone know of a high output alternator that can take some RPM.
.
I have a 145 amp alternator someone did local thats fine to 7300rpm.
If you are having voltage issues stick a voltblaster on there, at WOT it ups the voltage to 15-16 volts. Helps keep the ignition and fuel pumps going. Been running the 145 amp plus the voltblaster for a year with no problems. My car had a crapload of voltage drop when everything is running and after two or three passes with the stock alternator the car was at 10 volts WOT, sucks when the car is drawing more then the stock alternator puts out.

The issue was it went WOT and stayed there, even after the boom, i had to shut the key off to bring the rpms down. Now, with or with the MAF it goes wot at the rpms sky rocket. I am sure glad it was dry hit, and prob some sort of lean backfire, not really sure exactly what happened, but my big $$ motor seems fine.

Told you back fires happen with dry nitrous systems as well. Its just that wet systems are usualy for violant do to the added fuel vapors in the intake.
However wet or dry if the system or tune up is not right backfires can happen.
Glad everything checked out ok.

I see it.
Thanks again

**** this car !!!
Tried the voltage booster and Shiz's 160amp truck alternator and it helped but not enough.
I guess we are going to try switching from a 4 noid set up to a 2 noid.
Or I'm going to put a motor converter in it, take the DP off and drive it around.
Talk about frustrating! I may not be bringing the car to Memphis.

are you sure its not a bad noid...have you tried putting two batteries in parallel (to keep them at 12 volts) to see if the extra capacity prevents the drop? maybe up to a larger gauge wire to prevent voltage drop?

I'm not sure but they are brand new.
When we tested the kit (off the car to check the spray pattern) they worked fine and that was off a 1/2 dead jump box.
**** doesnt make sense Steve is firing 4 noids with no problems and everything I have is an upgrade from what he is running (alternator, battery, feed wire)

wasn't the nitrous' fault...I'm dumb. I had just installed a zex kit in my 98A4 jetted for a 75 shot. Now, at this time I had never used nitrous before so I was very nervous. To make a long story short, I did my burnout in first, activated the arming switch, staged and took off. I all ways race in 3rd NEVER manually and I was so nervous that I left the bitch in first after my burnout and never put it in 3rd. The car hit the rev limiter hard, backfired and turned off. Nothing blew up but my lid broke.
