official 1/4 mile track times

SG4247 · 08-20-2020, 12:45 PM

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.

jchammond · 10-06-2020, 03:49 AM

I’ll be back fellas, by next fall

Gonna be built & boosted this time

Gonna do 1/4, 1/2 & would love to make it out to the Texas-Mile

SG4247 · 10-10-2020, 01:32 PM

So I took WHITERICE to the dyno today, just to see where its at - since it ran a pair of 11.93's at the track last week on the Nitrous Express GTR dual plate kit.

I had the system N20/E85 jet sizes off by a couple thou, maybe because the DA was higher today, but I got a some good pulls on it.

Its a 7AT pulling in 4th gear, with the factory 3.36 rear gear replaced with a 3.69. So the numbers are a little wonky.

Found a safe nitrous tune with E85 and a 100 shot showing 11.6 AFR, which is very close to my track tune. This is just a DeutchWorks 200 pump upgrade (returnless) and GTR injectors, GTR dual nitrous plate kit. 3" aam exhaust and Motordyne resonated test pipes - Stillen intake. Remote Etune by SEB.

I can get more from it, but the shop owner had to leave.
I am happy with the data. I was able to log the dyno runs with EcuTek, standing next to the car with my laptop. AFRs were the same between the dyno and my logs.

388 HP 341 Torque

SG4247 · 10-17-2020, 10:41 AM

So, I took the lessons learned from the dyno pulls, and took WHTRICE to Thunder Valley last night. Conditions were excellent for going fast. Density altitude at 1000 ft, with temps in the high 50s.

Used the exact dyno tune from the post above, which only made 388 HP and it ripped of an 11.589 at 117 mph.

There is still more power in it to be had. Car was right at 3400 lbs with driver and 1/2 tank of E85.

Nitrous bottle was lower than I thought, and I actually ran out of juice on the 11.90 run.

Pleased with the progress so far, and impressed with the raw torque that Nitrous gives these little VQ engines.

This is essentially a 100 shot nitrous tune. I have jets for up to a 200 shot.

This was a 1 second progressive ramp from 20% to 100% at WOT. I was really tempted to cut the ramp down .5 seconds.....

SG4247 · 10-17-2020, 11:15 AM

Here is the Throttle Position, AFR and RPM log from the 11.589 run last night.

A couple things wrong with it. One issue, is the lean spike when the N20 system activates, and the other is the longgg 4-5 shift.

The 4-5 shift I can fix with some 7AT valvebody mods, the lean spike however has been a challenge to deal with.

Any suggestions would be welcome.
