My car was built to go to the strip, but not built for the strip…if that makes sense...so I try to get it out a few times a year for some fun. Last fall, after getting my new motor together and tuned, I ran it in True Street during Civil Wars at Rockingham Dragway(NC) and ran a best of 12.589 @ 116.56mph. However, that day I was fighting the factory tensioner that couldn’t keep the 6-rib belt from flipping out of alignment during shifts and eventually shredding itself just before the stripe. Then shortly after that race I discovered my meth nozzles were partially clogged.

Over the winter I put on a Gates HD tensioner, replaced the nozzles(and cleaned the old ones for spares) and removed the NGK R5671A-7’s for Autolite 3923’s. The belt was staying put during highway blasts so I felt confident to head back to the track and try it again. I also bought a set of 17” Alumastars with M/T Drag Radials.
This past Saturday my Fox Body club had a Drag Meet during a test-n-tune day at zMAX Dragway. I made four runs with the quickest being 11.631 @ 124.45mph, followed up with a slower 11.914 @ 125.73…but that mph was encouraging.

Yes, this is my car “digging” in…lol…Maximum Motorsports suspension isn’t very 60’ friendly!

Meth Injection nozzles require periodic cleaning. Residual solution in the nozzles will dry out and crystallize, over time it builds up and begins to hurt flow. Snow’s nozzles can be taken apart and serviced and I would suggest you do this 1-2 times a year depending on driving(meaning if you drive a lot, perhaps not as often because you’re constantly running fluid thru them, whereas my car can sit for a few weeks straight sometimes).
A little more than a year ago I was told to run the NGKs. I re-gapped them at about the 6 month mark and they’ve run fine in my car the entire time. Recently I stumbled on the fact that the NGK’s have a 5/8” reach where AFR recommends a plug with a 3/4” reach for my heads. I decided to try the proper length 3923’s and guess what, they run fine too. I don’t put a lot of stock in spark plugs, as long as the car pulls clean with no hiccups or misfires...run ’em!
Lastly, the question often comes up about how long a tank of water/meth will last. Of course that depends on how much you’re injecting and how often you’re in boost. I run 2-625ml/min nozzles pre-blower and my controller injects A LOT to keep the KB cool. Here’s a pic of my 3qt reservoir after four 1/4mi blasts.(about half empty)
It’s another fun weekend ahead as I ordered some 26” ET Streets that’ll be here tomorrow so back to zMAX on Saturday in search of lower ETs. Then putting on my 17x9s shod with Hoosier A6s and hitting a local SCCA Auto-x on Sunday…then that MM suspension will be more in its element!
