Hi, i just changed my ZEX 55 shot and upgraded to the 75 shot. Its a dry setup, i have not run a bottle yet w/ the 75 Oh, i also put a bigger fuel nozzle than what it calls for, so, im runing a little more fuel w/ the NO2.. SO HERES WHAT I GOT, IS IT SAFE OR WHAT??
--Walbro 255lph High Flow fuel pump
--nice and cold NGK iridium plugs
--Injen Race division CAI
--SR 4-1 headers
--2.5" catback hayame exhaust
--stock internals

i know i should upgrade the pistons and such, but will this be safe for the 75 dry shot?

you wont harm the internals with a 75 shot as long as your not running lean. you should be totaly safe with your setup.

yea, im already running super rich, can we say S-AFC?? LOL... well, thanks, any more input would be appreciated.

Don't bother with the S AFC.
Check your plugs or get your a/f ratio checked while on a dyno during a nitrous run.

The fuel pump maybe too big for your application.

yea, i have a A/F gauge, and when i floor it, it sticks to RICH... when not, it bounces back and forth between rich and stoich. yea, im gonna do a dyno in a few days

Let us know about the results. Doesn't Zex recommend a 4 degree retard on a 75 HP shot? S-AFC won't help you when using NOS. This was the conclussion from numerous discussions on hp.

GET THE ZEX PLUGS!!!!

Also make sure the fuel hoses are SUPER TIGHT

i ran into a small problem once, because of both of these reasons frown

yea, the ZEX plugs sucks!! ive had 2 sets and both have fouled in 500 miles, the iridiums are spotless after 6000 miles of NO2 use

My Phantom jumps in the OTHER dirrection. From Stoich to LEAN. I'm ONE-TWO tick marks from being in the LEAN area. Is this an issue?
