Default Irwindale Raceway2016 Part 2 "QTR TNZ" Thursday Nights Come Down See The Excitement

I started this thread back on 8/21/2015.
"Taking the 85 to the Irwindale Drags Saturday Night anybody else interested?" With over 21,000 hits and a lot of obstacles in our path D & R Racing LLC would like to thank you for all of your support.

It's now 2016 and Dale and I on the right track to be able to say "QTR TNZ" are in our sights so I wanted to start this new thread with our dyno results and Test and tune.

"Irwindale Raceway 2016 Part 2 Thursday Nights Come On Down And See The Excitement"

Yesterday Dale , Gale and I went to R & D Dyno in Gardena CA to see what we had or didn't have with my 509 Big Block. The first pull they used the Dyno results to see what needed to be adjusted and came with A/F motor was running lean and the jets were too small for the 950 Holley so they changed them from 76 to 80's on the pri. bowl and 84 to 88's on the sec. The timing was set by another shop to 38 so they backed it down to 36 total timing. The next two pulls were almost identical at 491.50 HP @6000 RPM @ 491.07 Torque at the rear wheels. I guess with the TH400 25% Power Loss that's around 653 HP at the motor. Not bad and we have room for improvement. I guess by installing 1-inch Phenolic spacer on the intake/carb. to keep the fuel cooler we could pick up 10HP for $24.00

Here's the Dyno pull and results.

Next we went to Irwindale to see what the truck would do.


Two runs 1/8 mi. E/T's 7.17 @ 99 MPH 60FT 1.63

We did it the front tires showed daylight between the asphalt and tire.


Give it up for Gale he was eating rubber while filming.

Here's from Dale's vantage point.

We're now doing the G-Body Twist.

I chocked this run but Gale got the worse filming from the rear tire.

Stay tuned this should be a good couple of months and come on down to the track it's a blast plus there's a wealth on knowledge to be had on motors just ask.

First point of business is shedding weight. We already have a Harwood fiberglass pin down hood that will shed close to 75lbs off the front then hack a 1/3 off the 3-inch exhaust from the rear tires to the rear end of the truck and install Flowmaster 44's or Dynomax Hemi Super Turbo's out the rear wheels. The extra pipe will save money modifying the system .

@ $198.00 ea. fiberglass front fenders are being considered also. Inner door panels will be changed with Alum. door panels, shed the electric door locks and go to a single headlights up front..

From what I'm told every 100lbs shaves a 1/10 off the E/T so 6's are a reality here quick. After one run last night I was informed by Tech I must have my flame retardant jacket on while in the truck. I have noticed lately the tech inspection on my truck is getting more attention. Their now on there knees looking under the truck and checking all SFI/NHRA required equipment for date codes and class. I HAVE NO PROBLEM WITH IT SAFTEY FIRST!!!!!

Congrats!

Your driving has gotten better and more consistent. What does your converter flash to and what rpm are you crossing the line at?

It doesn't appear to be spinning. A looser converter would probably help. Definitely if the one you have now only flashes to a little over 3,000. The video's you just posted say you launched at 4,500 on one pass? If it flashes that high, that's good. What size is the converter, probably 10"? What RPM did the motor make peak HP. You want to cross the line above the peak.

If you watch the launch where you're running against the KITT Firebird there's something goofy with the launch. Looks like the trans brake releases and then grabs again. Or something like that. Definitely a stutter there after it starts to move.

That was me getting excited and shifting into second after releasing the trans brake button.
