I just did this job about a month ago on my 94 with 172k miles on it. The leak wasn't bad but it nice eliminating one source of dripping oil..

Scary night out at the track last night, came too close to destroying my engine. First run was solid, ran a 16.28 at 83 MPH. The next run I missed second gear and heard a loud pop which was my intake tube blowing off resulting in the wire mesh from the MAF becoming stuck inside the throttle...

My new nitrous line finally came in the mail, got it installed and did a few test hits and everything seems to be working good. Can't wait to get it back out at the drag strip.

Some unfortunate news. There's a leak in the main nitrous line that I found last night and I won't have the time to replace it before racing starts today. Still going out to the track, I'll be just running without the nitrous for bracket racing..

It's a nitrous purge. It's purpose is too clear the nitrous lines of any air pcokets so you get a clean hit. It can also be used to relieve bottle pressure if it's too high.

Well it's been a while since I last updated this thread. Ever since transfering to the university last Fall I haven't had much time to work on my Explorer. Few weeks ago I crossed over 150,000 miles so I did a transmission fluid change and it shifts a little smoother now. Got the nitrous bottle...

Thanks guys. It started up and drove fine to work the next day then the battery was completely dead when i got off work. It wouldn't jump but I've had that battery in the truck for over 5 years and I think it finally quit. Not sure if that was the issue but it's running fine now, I'll be sure to...

Hey everyone, I was driving my 1994 Ford Explorer 4x4 5-speed tonight when out of no where i lost power and had to keep applying throttle just to keep the engine from stalling while in 3rd gear doing 30mph. Came to a stop and it stalled. Engine starts no problem but as soon as i start to...

Thanks! I'm always thinking about ways to go faster but money is always an obstacle. Nevertheless, I have so much racing it even though it ain't the fastest thing at the track

Haven't updated in a while but still running great. Went to the track three weeks ago and made it the third round of bracket racing. Bottle heater is working great and has no problem keeping the pressure up. Nothing really new on the truck for now. Anyone know how often i should be replacing the...

Never got the chance to go out to Julesburg last month. Both weekends were canceled due to snow and rain so I won't know for a little while what I'll be running ET wise but the nitrous is working perfectly. Starting to get familiar with the bottle heater. I think it'll really help with...

Just the nitrous one. I had no problem spaying fuel.

Spoke with NX today, They said that the plunger in the solenoid got stuck due to not being used for a while and the coil is not powerful enough to reopen it. Cost me $30 to get it fixed and they'll be shipping it tomorrow. Just in time for Julesburg on the 15th.

When i was in contact with them they said that it could be a bad coil but hopefully I'll find out what went wrong when I get them back.

New intake is on. Works well with the BBK throttle bottle. Two week ago I mailed in my solenoids to Nitrous Express. Once I get that back I plan on putting that back on as well as the bottle heater. April 14th is Julesburg Dragstrip's opening weekend. I'm hoping I'll be able to make it out...

www.summitracing.com/parts/ASP-526400 It's for the 4.0 Mustang but from what I know it will fit the 4.0 in our Explorers. I'm not sure what belt length you would need though

Got a bottle heater. Hopefully will bring faster and more consistant times. Still wanting to do a mild rebuild with 95tm heads and the 422 but likely won't have the time till at least this summer.

Late birthday gift? Glad to hear some good news!

The Explorer weighs 3960lbs with me in it and the spare and passenger seat removed.

Good to know. Thanks! Once I get down to a 1/4 tank of gas I'm going to stop by the landfill and finally weigh my Explorer.

That's not worth it IMO. Do you think getting a exhaust cutout for the track would help or hurt performance?

I'm planning on getting the 422 cam sometime this winter and hopefully 95tm heads if i can find some in good condition from a junkyard. Likely be doing some port work too

Stumbled across these today. Never heard of the company, could be junk, but the price caught my eye. What do you all think? https://www.protuninglab.com/90fora91ex4v.html

I do think all these struggles will be well worth it in the end once you really get it running. Good luck!

Can't wait to see some dyno numbers
