Black Jack: No TnT, but installed Zeitronix dual wideband

So, that was my fastest 1/4 on a 100 shot with an iced intake, which was good for maybe 1mph that day in the 1/8, but was actually a tad slower than earlier in the day than my best 115mph trap speed. I was doing better driving that day than I did after a year without practice at foxtoberfest. I'm happy with the pick up in trap speed, but honestly, it's not that great for what should be a 50hp pickup.

Anyways, the 92.8 in my recent foxtoberfest runs converts to may 117mph in the 1/4, though the ET would not have been an improvement over the 12.02, IMO.

For me, the loop is further back, and also, just an observation, the directions indicate that his bottom part of the loop is inverted, as they call for the bend to push up into the DS tunnel. But anyways, about 4" further bakc, I'd guess is where the T56 wants it to be mounted.

yeah the bottom part actual copys the contour of the pan in that section so his is upside down, A copy of a copy of a copy of the hpm loop so probably made in China now lol. I didn't realize the t56 was that much longer.

you have this in the old 100shot post you linked, "Edit: Note to self: This was run on the 125 fuel pill with the 100 n2o pill"

the jetting I can find for the kit you listed would put that at 46/34 where it calls for a 46/30 on there "100" shot,
there 125 is 54/34 for that kit no other jetting listed above it. Kit should have come with. 026" .030" .034" .040" .046 ".054
Only kits I can find listing a .067 as a 150 shot Is using a .038 fuel jet and is there high output wet kits that uses better individual selonids not in a control box. Edelbrock groups has made a mess of that brand and many others though so info isn't the easiest to find and may not be current, pulled the jetting from Jegs old PDF instructions on it

This run was .067 on the nitrous side with a .032 fuel. thats a decent jump in rasing the nitrous and lowering the fuel from the "100" shot, the 100 shots fuel jet was larger than what your currently using from your note in the post. I expect the 54 jet is about the limits those selonids will flow and your 100 shot jetting pass should have been pretty rich, you might want to try there 125 shot jetting with .054/ .034, and if you have all the listed jets it came with plus a .032 you can test it with the .032 and .030 on the fuel side, I bet it picks up the more fuel jet you drop. Your all ready using a smaller fuel jet with a much larger .067 which will flow enough for about 170hp gain when its the limiting factor. Just bring fresh plugs and read the timing strap and fuel ring after a pass. its a hassle but only real way you can dial nitrous in, and you would be suprised how much you can pick up doing so. .052 nitrous jet is almost always good for at least 10mph gain over na trap speed in the 1/4 once its dialed in, in my experience on these types of combos. So there "125" shot cleaned up should be able to better the current jetting your using and should be within the limits of the selonids.

Good info. I'll keep that in mind if I run into anything with 'em. Don't suppose you have the part numbers for the 3' leads and whatever you used for a timer? I'm happy to wait until there's a verified problem, but it'll put my mind at ease that there's already a known solution if I do run into that, too.

The shorter leads are available at Zeitronix.com---> order---> scroll to bottom where seperate cables are listed---> select drop down option for your cable length..(3',10', 20')

As for the wideband power up delay, my engine management looks for RPM and won't send power to the wideband controllers until RPM exceeds about 250 RPM. So i don't get any power to the wideband controller with just the key on. I dont recall what you are using for tuning. Maybe you have an extra configurable output to use that could be tied to RPM signal, or oil pressure. If not i did have a really slick oil preasure switched setup before I went to a stand alone. The info and parts #s are in post #11. I used a pressure safety switch to ground switch the wideband relay.
