I have a zex system on my 2005 GT 3V. Currently running only the 100 hp jets with a nitrous tune (sct) because I can not find a colder spark plug for the 3V. Does anyone know of a manufacturer that offers a colder plug yet?:?: Until then the 150hp will have to wait, better safe then sorry:help:

what else are you changing for the nitrous besides plugs? dd you have to retard the timing? or will you for the 150? did you need a tune? can you use the sct tuner with nitrous? will the 3v take the full 175 shot?? (im thinking about ZEX for mine, and info would be greatly appreciated!:kooky:

So far I have run many, many runs at the 100hp level with no problems at all and the only modifications being the cold air kit, tune, and exhaust.
You will need a tune. I use SCT. The tune I use turns off the traction control, raises the shift points and redline, makes the shifts much, much firmer, and retards the timing. For the 100hp setting, I actually just have the stock fatory timing (since its not aggressive at all). But to run the 150 the timing should be retarded about 4 degrees and you should run colder plugs. AND OF COURSE, always run the best gas available--not 87---run 92 octane.

Also, the SCT has room for 4 programs. I have the original Factory setting, one program for 100hp, one for 150hp, and one for non-nitrous just using 87 octane. To flash the computer takes literally just seconds.

I just went to the web site and it came back saying it has no spark plugs for a 2005 Mustang GT. What gives????:?:

Edit: Just went back again and put in just the part number. It shows the plug (at just over $10.00 each :eyebulge: ) without an application to what it fits.

PSFRacer, I have a few q's for you. Did you get a dyno tune for your 100shot?
Did you run that 12.63 on street tires? And how much does it cost to fil a bottle?
Thanks
Sean

I noticed the same thing but I read on the other post about Got zex installed that limestang05 said that part # ht1 is factory plug and ht0 is the colder plug, maybe you can call them up (www.sparkplugs.com), I will try to do it today if I can find time at work. Yes the $10 is a lot but well worth it if it saves your engine!!

I got my plugs in the mail yesterday. Remember, the number is HT0-(ZERO). I was charged $9.27 per plug. (dealer cost?). Anyway, I had to call cause the computer wont pull up that number and the first girl I talked to had trouble too! She got me in touch with another guy who works there who just so happens to own a super-charged '05 and he had the whole scoop. I think his name was Mike.

Even though the price seems high....try to buy replacement plugs from Ford....I think they are around $13 each. When you look at them you'll see that they aren't like anything I've ever seen before.

My Zex kit still hasn't arrived yet, but I called a couple of days ago and found out that it had not been shipped! The company that I bought it from on Ebay forgot to ship it....six days later when I called them, they were so deperate to make it right that they offered to refund me $100 or throw in a "purge" kit. This may not sound like much, but the kit was on sale in the first place for $499.88! I took the purge kit because I was going to get one anyway and they cost alot more than $100.

Unlimited Speed? I am waiting on one from them off ebay. They don't admit it but I suspect the same thing.

I goofed my previous post. I'm still waiting for the same reason. PSFRACER, are you able to drive around town with the nitrous tune? Diablosport was suggesting I change between daily driver tune, and nitrous tune.

I drive back and forth to work on the 87 octane tune, the shifts are much more crisp, I hate the factory settings...the shifting is so sluggish. I actually carry the Xcal 1 in my car, because changing the tune takes just seconds anyway. If I think there is any chance I may use nitrous, I just load that tune. The tune I have for the 100hp is easily driveable everyday also.

I run the Xcal 1.....if anyone has stepped up to the XCAL 2 and thinks it is worth it let me know...I am curious.

I ran 12.63 on street tires...if you see my mph it really shows, any car going 110 in the 1/4 should be in the 12.30's. I did not get a dyno tune, and it costs me $3.50 per lb to refill the bottle. Some places charge as much as $4.00 per lb. Still a bargin if you as me, considering I didn't have 5k laying around for a nice SC.

At one time I wondered myself if it was worth it. I went to the XCAL2 and it IS worth it. XCAL2 holds more tunes, you can change parameters using Extreme tune software and last week my tuner made some changes where I can change parameters using the XCAL2 as a stand alone, no need for a laptop or software.....very cool!

Got the new Autolite #HT0 plugs in today. I took close up pictures of the difference of the colder plug vs the stock motorcraft plugs if anyone is interested. The pictures are in my gallery.

Also, I have pictures of the stock plug after some passes on the 75 and the 100hp setting on a Zex kit. I use a tune from SCT, but the timing is just factory stock, used 91 octane gas.

I found a Unocal 76 which sells 100 octane (at $5.99 gal:eyebulge:) , has anyone run the 150 shot yet? I am going to try the 150 when I go to California Speedway on November 12th. I figure the conservative timing, with colder plugs and 100 octane gas, I should be fine. Any thoughts?:?:

Can't you run your NOS tune at all times...?? Maybe that's just GOOD custome tunes...?? since your ZEX/NOS is set to kick in at WOT it can be tuned to run a 'normal' 93 oct tune till that point, then it will move the timing to alow for the nos mix...

No clue with 100 blue + gass... you're really playing with the timing on that one.. would have a pro tuner to look at it and make sure it's safe on a dyno with data logging!

Hey KJ,

Any shops you are willing to recomend in SOCAL area? Bottle Blown Racing looks good, any others?

I think your right....even though I have been running the 100 hp setting with no problems at all, its time for a dyno tune if I want to get serious....
