how much of a shot of NOS would be safe/max on a stock 1.8 beta1 automatic tiburon?
|
Not sure if stock or not. FYI, He said:
(01:51 PM) Tony Vendetta - like what other mods? i have 4-2-1 headers complete catless exhaust, strut bad, and a cold air intake (01:59 PM) Tony Vendetta - btw I have 125k+ on my beta1 |
55hp or less is safe. Max would be 75 according to manufacturers.... Nitrous adds heat, so if your engine gets too hot, it will melt parts like your piston rings. Play it safe. I run a 55 for messing around, but sometimes I put in the 75 shot at the track. It's a simple matter of changing the nozzles.
|
I would not run a 75 without upgrading the fuel pump.
|
Where are you getting that figure? I've run it just fine.
|
From my wideband. Did you have a wideband on yours?
NX produces a ton more power than any other kit on the market. I've tried the NOS nozzles and they're shit. I've also found that you need to retard the timing a great deal at that point also. Not a lot of ECU friendly options for that. |
^^ The newer ZEX nozzles adjust fuel to the level of nitrous being put out. That means you'll always get the stoichometeric ratio, or close to it, no matter what your bottle pressure. That's what they claim at least. I don't see how it can get much better then that. A venturi is a venturi and they suck fuel into the nitrous stream by passing the nitrous at high velocities by the fuel.
My local nitrous shop said they've never seen a problem with anything that came from ZEX. I'm really not worried about a wideband reading. The ZEX kit self tunes. I'd like to get a fuel pressure reading while running nitrous to make sure i'm still at 36psi or higher. |
And how does the Zex kit magically know that you're leaning out? Does it include a wideband sensor? It increases fuel pressure, but without a wideband or O2 reading, it's not going to know you're running out of fuel.
