So, I installed the Nitrous Express GTR dual plate nitrous kit that was originally installed on CarbonZ’s car by Z1.

Very pleased with the system overall. I am on E85 and have the original factory fuel pump from 2010 model year with 50k miles on it.

Seb wrote me an E85 + Nitrous tune, but we are seeing lean spots from the factory pump not keeping up with the demand when nitrous is on. No suprise.

Anyway, took it to the dragstrip last night, and made some decent runs in the heat and humidity. New pump and CJM top hat is here waiting for install.

12.399 @ 113 mph - new nitrous record on a 75 shot. There is lots left in it!

Keep forgetting about this thread. Nothing to write home about. 2nd time at the strip since purchase. Stock with Z1 intakes.

Most calculators say 385 whp at 3400 lbs is 12.05 ET at sea level.
That car is fully gutted. Trunk/hatch panels, spare(obviously), door panels gone, bumper cut, and I think even the passenger seat...and something like 340whp iirc

I have mine down to 3360 lbs with a 240 lb fat azz driver. My car is pretty stripped down at this point. Bone stock, it was 3610 lbs with driver. So, I've removed 250 lbs.

At 2950 lbs with 340 whp - this would get you barely in the 11's in the right conditions.

I would like to get mine down 2950-3000 lbs, but I really enjoy the AC and the radio!

Went to Thunder Valley last night. New Deutch Works fuel pump.

Car had the 100 shot in the NX GTR kit. Really humid and hot, so the motor doesnt like that humidity or heat.

Now it wants to wheel hop going into 2nd, and I have a stumble when the system activates.

So there is some work to do to sort it all out.

Its cooled off here in Okla, so its a nice 65-75 degrees finally.

Intstalled a Nitrous Express MaxEz progressive controller to help modulate the flow of nitrous and fuel to the motor. This really helped the engine, tires and drivetrain over the old school on/off solenoid.

At this point, I have the progressive coming on with the TPS digital switch at WOT. Then the progressive starts at 20% and ramps up to 100% over 1.0 second.

SebZ had been extremely helpful to get the AFR correct, so I dont tear this deal up.

Old lady rode with me, we had a good time!

Car runs excellent with more tuning to do.

Went out to the track last night, lots of racers showed up due to cool weather here in the 405. I was literally surrounded by rustangs and smellcats in the staging lanes.

Made a no nitrous hit on the nitrous map and went 12.907, against an old buddy ive known for 25 years in his V8 S-10 pickup sleeper, he went 12.95.

Then made a couple of nitrous hits with 100 shot. I thought it would go quicker, and the AFR looked really good, so might need to ADD MORE SPRAY.

That's crazy... You are spraying 100 shot and running the same time as the record n/a car... Odd

The track scales were showing I was at 3465 lbs with driver and 10 gal of fuel.

So, most calculators show 402 hp needed to go 11.939 at 3465lbs at sea level.

I was at 1300 feet, which would make the HP more like 420.

Exactly what the dyno says, 320 plus a 100 shot.

Are you open diff and are you spraying off the line? My 350z on a 75 shot went 12.0@114 but with a 1.6 60' spraying out the whole.

I have the 3.69 factory VLSD. It generally works pretty well.

I have the NX cheapo MaxEz plug in progressive controller starting at 20% when it goes WOT, then up to 100% in 1.0 second. This is basically 20% to 100% over the duration of first gear from 1800 to 7500 rpm.

It would go quicker in 60’ if I shortened the ramp
time down to say .5 seconds or 0 seconds, but I dont want to hurt the motor.
