nitrous bogg
nitrous bogg I just hooked my nitrous up on my 98 z28 from a dry shot to a wet and now when I hit the nitrous the car kinda boggs for a split second then comes on It never done it on the dry shot so I figured that maybe the fuel jet is too big so I put a smaller jet in it and it still does it not quite as bad I don't think but it still does it I'm going off the jet calculator on the Internet could the jet still be too big or am I running too much fuel pressure because I don't have a regulator on the fuel side of the nitrous
its nos brand silinoids its a sniper nos silinoid and a power shot fuel silinoid with a 78mm nos plate what size jet would you suggest

Getting a good plug reading would be very helpful.... would tell if it is a rich or lean condition causing a stumble.
Be careful - an excessive rich condition can cause lifted ring lands and other piston damage, and extended lean conditions can increase cylinder temperatures.
You didnt mention how big of a nitrous jet youre running... but sounds like you have an issue with Nitrous/Fuel ratio.

No one has asked it so I will. Where are u pulling the fuel from??? I had that same kit at one point. On a 150 I was at 63 n 34 fuel. I ran out of fuel jets and I just so happend to have a 67 n jet swapped it out and I finally got the afr around 12.0 and the plugs looked good. Oh and BTW if it's the same kit I'm thinking of the fuel line is way to long it needs to be shorter which will also give u that bog/ delay

I'm pulling fuel strait from the fuel rail and which fuel line are you talking about the one from the rail to the he silinoid or from the silinoid to the plate now that you mention it I'm gonna go out on a limb here and say the one from the silinoid to the plate because it's probably because of the drop in pressure to the rail and it takes it that split second to make it to the plate to make up for the loss of pressure on the fuel rail or at least that kinda makes sense to me anyway lol
Both lines I basically had to mount the solienoid as close to the fuel rail as possible. From rail to solienoid I made it hard line kinda like the nitrous outlet plate kit. But from the solienoid to the plate I measured the distance and order one that was a little longer than the measurement I came up with to be on the safe side
I have 4 kids and self employed mechanic so I'm on a extremely tight budget so my nitrous is pieced together and I had to make my own bracket and stuff but even tho its pieced together and don't look pretty it gets the job done well now it does anyway lol and again thanks for everyone's help on this issue
