Check this out guys, local Youtuber SGTR met up with me to do a few runs in Mexico. His old GT is surprisingly quick. Its modded pretty good and set up to be a dig monster. Tune, 3000 stall, Mickey T tires, and significant weight reduction as well as a few other tasteful performance mods. He told me it weights 3050 lbs with him in it! Runs 12's.
I ran him with no spray, and heat soaked. Excuses aside he obviously killed me on the low pull but the Jag pulled a bit on the higher roll. Will do some more runs in winter. By then I will have a few more mods too.
It's funny because I floored an F-Type, with an instructor, at Jaguar's "Art of Performance". The instructor said he would tell me when to brake, but I hit the brakes about 100m before that. Like it was limited space with a wall, and I was still liable for the insurance excess on this new F-Type...of course there was no wheel spin or drama given all the electronic gizmos.

On the 20, it looked like a long time till you got on the throttle and the front came up.
Yes I didn't react as quickly, and the car had to downshift into first gear before it started to pull. 15-20 roll just isn't a good mph to go from for the Jag because of the gearing.
Even if everything went perfectly on that pull, I think the Mustang would have still jumped ahead by a car until about 70 mph because that thing just has a nasty low end. He was telling me that the 3000 stall and rear gears is what really helps him with that.
Are you using an air fuel gauge when you spray 125? or using race fuel to offset possible detonation?
Both actually, I have a Nitrous bottle pressure gauge, boost gauge, and AFR. And I run 93 with 5 gallons of E85, sometimes a can of boostane if i plan on spraying it for an extended period or multiple times. I keep one in the trunk and a few in the garage.
Also, I run a low temp T Stat, and cooler plugs with a smaller gap.
I have basically the same setup as you and running a 75 Shot right now with no issues... I would like to try the 125 but it's a PITA to add an wideband...I was thinking of trying race fuel so I wouldn't have to worry about any detonation and see how I like it and if I do want to keep the 125 then add the wideband..
Hardest part about the wideband was running the harness under the dash. Took a lot of patience. But yea it makes a difference. Just make sure you're really on top of your maintenance if you want to jump up to 125.
What kit are you running? I have the nitrous express proton with piranha nozzle and lightning valve. Also have the pruge kit and bottle heater installed along with an in cabin bottle pressure gauge. That and obviously all the safety stuff... Blow down tube, fuel pressure cut off etc. Was pricey, but you get what you pay for. And going cheap on nitrous equipment can cost you an engine or worse...
Jazzy I have basically the same set up as you. Curious were you able to weld in the bung for the sensor without removing the exhaust? Also what are your afr's spraying 125? Thanks
The bung is easy to weld on even with the exhaust on. But i happened to get it at the same time i was having the custom 3" exhaust fabricated and put on. I just gave the shop the bung and asked them to place it on. They knew exactly where to put it.
As far as AFR's I shoot for around 12. I keep an eye on it and adjust the mix as needed. Better to be slightly richer than lean. Boostane is added insurance. Since i don't drive the car as much it lasts a while. I bought a box of 6 cans a while back and haven't gone through all of them yet.
Not sure if i will keep the AFR around 12 though (might be slightly adjusted). I will be taking it to the dyno again soon once i get the 83mm throttle body on. I just put on a ProM 92mm MAF and will be getting a larger J tube as well. The plenum is currently getting ported too. Once i get those on, I have a meth kit sitting in the garage i want to throw on, I am sure I will need to readjust the fuel mix and might shoot for a different AFR depending on what the guys at the shop recommend.
Your set up looks nice. It looks like you have a remote opener right? Thats the one thing i didn't get. And mine is an arm switch with a WOT switch. I thought about the rpm window switch, but didnt get it. At least not yet. How did you mount the controls/switches inside?
Yes I do have a remote bottle opener so the power is there whenever I need it. My system runs off of the TPMS sensor voltage. As soon as the controller sees wide open throttle voltage it engages the nitrous.

Modded 2V Mustang GT vs XJR
he obviously killed me on the low pull but the Jag pulled a bit on the higher roll. Will do some more runs in winter. By then I will have a few more mods too.
