well I don't post a lot on this forum but I thought I would share a little experience from this past weekend at Fun Ford in Texas.

I changed solenoids from the NOS to the Induction Solutions solenoids and purchased their fuel flow tool to check pressures. I had been running 6.29-6.35 in the heat with the old set up flowing 5.25 pressure through my electric gauge which is mounted on a pod in the car. Once I changed solenoids The system only flowed at 5 psi so I increased the pressure to 5.75 and changed the fuel jet from a 22 to a 20. New set up was 24 nitrous 20 fuel and 5.75 flowing pressure.The car responded very good with new personal best and the elusive 9 sec time slip. Unfortunately the car burned the #5 plug strap on the last pass. The car was dialed in at 9.73 and it ran a 9.89 and was off 4 mph. Come to find out the plug heat range was a little hot for the new tune. E85 likes a hot plug so I run -7's and the since #1 and 5 are a little lean on a SBF I nipped plug.

I am still happy with the weekend. I burned the # 5 exhaust valve so I have some work to do but all is good. The plan is to go to a # 8 heat range and Lower the nitrous jet to 22's in the corners. Looking forward to a little more power as the tempm cools here in Texas. Hope someone learns something from the post

I can't even imagine what a 9 second pass is like or a 10.

They are similar to 11s passes, except they are over quicker, and your smile muscles cramp-up all the time.

Cahorne - have you been tuning your ignition and fuel with your spark plugs? How are they reading? If you're not running a WBO2 and EGT set to fine-tune - I would. Nothing beats max power and peace-of-mind in one shot.

I have ran the Wide Band for tuning purposes prior to the solenoid change. I did not figure the solenoid change would make as much difference. I usually pull a plug out of #1 about every 10th pass just to take a look. With E85 the plug is always so clean it is a little tough to read but for the most part the timing marks and heat have looked good. I am pretty sure I had the right amount of fuel and timing taken out but the heat range of the plug was too hot. NGK-7's are great on E85 N/A but I should have put in a colder plug especially since I was running 1/4 mile for the first time.

In related news... The exhaust valve seems fine but I think I hurt a piston. I do not have a leak down gauge but I put 100 psi in #5 hole and the air was coming back though the crank case pretty good and nothing through the exhaust. A new piston and ring pack might be in my future. I hope it is nothing else. Last week was very busy so I have not got the head off yet but I think I will get a look on Wed or so.

Thanks Frdnut. I like the people on this site but do not have the patience to wait on this site!!! I guess it is my short attention span but the incredibly slow updates of this site wears me out!!!

Congratulations! That car has had a lot of changes from what I remember. Always love to hear about a fast early Mustang that still looks like it could cruise down the street.

Thanks Nate. These cars are always changing.. But I did drive it on the power tour this year and had a blast. Beleive me it gets plenty of cruise time otherwise I would have a c4 in it..

Uhm, that irridescent bluish purple color on your sparky plugs mean they are getting berry hotta, LOL.

Track buddy was playing with the nitrous on his 5.0 mustang and almost welded a plug to the threads
on his aluninum heads. It would not come out so I just suggested without knowing much about all this
that he wait until the heads cooled off. Apparently it worked. I don't know if he burned a valve or not
but the spark plug pin was completely gone.

That is what y'all get for running blow torches on your engines.

Can't stress enough about tuning. If you don't tune it like a cutting torch, it won't burn up. Tune. Tune. Tune. Oddly enough, the right fast parts make your car fast, then it breaks. The right fast parts + solid tuning make it even faster, yet less likely to break. The cheapest part you can put in your car for higher performance and better reliability is tuning. Unfortunately, the end of the build is when most folks are already over-budget and out of patience, and tuning takes a back seat. You're running an engine far, far beyond it's design limits, and there is no warranty. Things can go boom even when it's all seems 'right' under these conditions if you don't "herd your horses" for a moment or take anything for granted. Take the time to do it carefully and properly, and stay on it - as you can pay a little now, or a lot more later.
