rebuilding after the crash

It's a runner. It was fired up for the first time Saturday. Next week we will get the whole crew for a fire up. Immediately following will be a crew party. Video will be shot next week. All I can say is it's not the same car. More boost along with a bigger cam made it jump off the car lift. Crazy stuff.

 

Oh baby! Gonna be a good year for that rocket ship!

 

Can't wait for the video.

Cheers,
Harv

 

Looking forward to seeing the video. Congratulations on a successful fire up Brian.

 

Could not wait Brian ? I know that feeling there's been times, thinking about a change or what to do jump up put my clothes on go to the shop 2 or 3 AM and play with ,
Car jumping off your Pro Jack's. do you have pin's to lock your car to the jacks or you just raise it up on the frame,
I now lock / Pin my car to Jacks when I would run engine , especially wrapping the throttle,
I one time did a dumb thing,
Had a big blown engine setting on Floor
Be fore install, I switch to short dragster Zommies , Funny / Dragster oil pan ,
Strapped to floor , fired it up , brought it to temp, Blipped throttle about a 1/4,on a Buzzard hat
About 5,000 rpms , engine I shifted over 9,500 Rpms Tall BBC
It broke loose of straps , flipped over against injector and blower still running,
Luckily I did not have a soiled 1-1/2 fuel line from tank to pump , , it kinked off , keep fuel going everywhere, laying almost upside down still funning before I could get to mag kill switch
This engine power was little over
1,800

 

Yeah, but I bet you soiled your britches!

 

Yes, I freaked out,, most the crap I have done , It was like a drill ripping out of your hand , except close to 1000 pounds, I've been a one-man thing , my father was there but had no idea really what I was doing , I scared him in my blown 69 camaro 35ish yrs ago , low 6 sec 1/8 street car was fast then on L 60s

 

I put the car on the car lift. It's never ever sounded or responded like this. The cam was the last part I needed for a true nitro combination.
Today's fun besides snow blowing for over two hours was mounting the racepak. The blower needed to come off to mount a junction box. The drill didn't have enough room. I mounted the egt boxes. I ran the cables. Everything is connected at the engine. The engine is back together. Several other wires still need to be connected. Then the racepak needs to be programed to sync with the sensors. It was big progress today.

 

@racer-x
Just asking , casting or crack
Maybe did not see.

 

Just a line in the casting. The stage five intakes are heavy duty pieces for nitro duty. They can handle intake explosions. I just wish it wasn't so heavy. It's aluminum. Mag intakes are for 14-71 blowers. To run a 8-71 a adaptor is needed. I dont want to do that.

 

Thanks for all the updates. Looking forward to the video and hearing the new combo run. Would be really interesting to see some data logging and subsequent adjustments from future upcoming events if or when time allows of course. The time and effort put into this car is amazing.

 

Amazing stuff here, so much going on at once, and everything is critical! Over the last year I’ve been getting to help on a couple really serious Bonneville cars and it is very much a lot like what you’ve been doing with your car. The commitment to go really fast has to been over 100% or the consequences can be more than a pile of junk parts! Thanks to Ryan for setting up this board so we can watch in awe what you’re doing!

 

A mount was made to hold the driveshaft sensor. It needs .050-.100 clearance between the sensor and magnetic ring.
With all the sensors mounted it's time to run the wiring. The engine is wired so far. Now I need to connect the computer to the sensors.

 

Is the tailshaft sensor a Hall effect one (with magnets on the tailshaft), an inductive one (mebbe detecting a notch or drilling in the tailshaft) or some other form of electrical sorcery?

A simple magnetic design. It's like a light switch. On off the revolutions are counted. Mine has 4 magnets. Every 26 inches or so a event is recorded. This recording compared to rpm tells if you are spinning. Shock; air pressure; four link settings etc can be adjusted for a faster 60 foot time.

 

Those little magnets must be fixed on really well (Crazy Glue? ). I'd imagine that tailshaft goes from nothing to a bazillion rpm in the blink of an eye, and then some vibration.

Got me curious, as I recently fitted a crank sensor to Number One Son's car. It's the inductive type. Stupid me then put the engine in, and broke the sensor on the front swaybar. A shorter one will fix that drama.

Cheers,
Harv

 

Magnets they set down in a pocket
Blind hole , Step hole , from inside .
Big side faces the pinion / Yoke
I'm sure Brian will explain it better

 

They are pressed in. They won't come out.
Let's talk about these yoke rings. They come with different magnet configurations. Four is common. Some have as many as sixteen.
Sometimes the box determines the number. A older box might only allow four.
The reason to run more has to do with how sensitive it is. At the hit when the tire rotates a four magnet will alow the tire to roll further down track before a signal is sent. Think of it as fine threads or course threads. With fewer magnets tire slip could occur and be missed on the recorded tracing.

 

Like @racer-x said above ,
I my self over the years have had to do, Yoke Ring & ect , that I needed to drill & square off bore / holes to add more magnets as Technology changed .

 

The first first up went perfect. All of the cylinder temps were right on. The pan came off for inspection. It was perfectly clean. There is a video posted on my Facebook. It's crazy how loud it is now. The engine was fired on 35 degrees with 85 percent in the tank. There's no reason to go crazy on a warm up.

 

@racer-x
On warm ups , Do you use Nitro Oil ?
I would think You do ,
Also just curious , One warm up & One Pass per Oil change ?
Or 2-3 runs per Oil change,
Just in Oil , Nitro oil is $$ not including the mess and brake clean.

 

It's always on 70 nitro oil. On a 90 plus degree day I put in a quart of Lucas stabilizer. One warm up and one pass per oil change. Our warm ups are not very long. A little over 100 dollars per oil change.

 

Thanks for posting the fire up. I calmed it down for today. Last week it jumped off the lift when I hit the throttle. Nitro fire ups never get old even if it's just to make sure everything is working. It's about five weeks until we turn the tires in anger. There is still alot to get done before April.

 

Thats the famous nitro helper Jerry Newman walking around the car. Jerry's accomplishment are off the charts. He has been doing the nitro thing since 1959. He is a fuel system expert. Also in the video is Chris King. Owner and driver of a modern NHRA nitro funny car. The guy wearing the NHRA jacket is Andy Boehl. Andy runs a alcohol funny car and has won Indy with it. My usual crew man Mark Janacky was in the car. It's fun to get the guys together and burn some nitro. Having experienced eyes on the car is a big plus on the first fire up. Things can go wrong fast in a big way. They all know their places when it fires up. Safety is a big deal. Fire extinguishers were available at the ready. Unless you are regularly around these machines you can't imagine the danger. These cars are no joke.

 

Dear god that thing sounds awesome.

 

That video made my day

Jerry made me smile. Knows exactly what he’s doing, moves quick when he needs to, but also walks around like a room full of fire breathing hemi is normal. No earmuffs, not overly bothered by the fumes. Me, I’d have my fingers jammed knuckle-deep in my ears, tears and boogers flowing, grinning like a lunatic, trying not to wet myself a little.

What were the causes of the stops/restarts?

cheers,
Harv

 

That thing is going to be a real animal now! You better have your instincts on Kill when you put the hammer down.

 

we shut the car off a few times to make timing adjustments and to fill the alcohol tank. the timing is split with the grid. a magnetic pick up and trigger wheel is hooked up to the grid. to change timing the pickup is slid up or down. its on the drivers side. the mag fixed timing is set by rotating the generator. i can choose either timing setup by flipping a switch inside the car. we were checking both. rotor phasing was also checked. everything we do has a reason. whats not seen are the 16 friends and family watching the fun. they stay back.

 

Wow Brian the difference between last year and this year is completely different I can feel the power difference it’s even more crisp on the hit I can’t wait to see it run this year
