rebuilding after the crash

No it became off topic so I quite posting.

 

Maybe you'd consider moving the thread to the OT forum?

 

I bet it would fit perfectly in the off topic section here

 

^^^^^^
I'd ask one of the moderators to have it moved here to the "Off Topic" forum. Then we could all follow along.

 

I will look into it.

Not much to post pics of lately. That doesn't mean I haven't been busy. I have been checking things off of the to do list.
Time engine
Set lash
Mount parachutes
Bleed brakes
Reset anti roll bar
Changed out one bad battery for the starter. It takes four.
Made a new spacer for the idler pulley
Weld egt bungs in the zoomies
Got new ends on the starter cable.
Just a few things in the last week
I'm working on getting a spare converter.
Trying to get all the sensors for the race pack.
There is no off season this year.

 

The true potential of the car couldn't be used do to the small tires. Now that that's changed the engine can be tuned up for big power. To keep a eye on things and to aid in tuning a race pack data acquisition set up was installed today. We will be monitoring the following.
Egts x 8
Drivesha speed
Rpm
Oil pressure
Fuel pressure at the pump
Fuel pressure after the barrel valve
Manifold pressure
I will most likely add a trans temp.
The anticipated fire up date is in ten days. View attachment 6312314

 

Just suggesting,
can you add or expand with your RacePac model to include
Fuel Flow gph @ pump outlet
& oil pan pressure ?

 

For now this is the basic monitoring package. More sensors will be added in the future. The cost of these sensors is crazy. Both of the sensors you mentioned are on the list.

 

^^^^^
Yes , I have close to 7 in data logger & sensors , & I want expand to more data ,

 

So why spend alot of time and money on a race pack? There are many reasons. Here's just a few.
Blower boost. If the boost is dropping it's time to restrip.
Fuel pump pressure. If the pressure drops it's time for a rebuild.
Fuel pressure after the barrel valve helps the launch as the engine goes through a lean spot at the hit.
Driveshaft speed shows how the car is hooking up.
Egts tell you how hot a cylinder is getting. Lean is hot. Lean is fast. Lean can damage pistons. It's the way to get the most hp without causing damage.
So you can see it's about tuning and monitoring the condition of the parts.
The majority of piston damage occurs at the hit. Going from a rich condition to a lean condition has to be controlled. Adjustments can be made with data logged.
This is a very basic overview. More details to follow.

 

Just adding , there been times
Plug or 2 try to foul out , lean pump out
Plugs would relight , cold weather lean pump out to create heat

 

I run a high/ low valve to prevent that.
For those that don't know what that is a valve is opened to return fuel to the tank during the burnout. When the top bulb is lit the valve is closed giving full fuel to the engine. When watching these cars it's a noticeable drop in rpm can be heard.
So why do you do this?
It saves alot of fuel
The engines heads get hot to burn the fuel.
It greatly reduces the chance of putting a cylinder out at the hit.
We also use the valve on warmup so less fuel goes into the oil pan.

 

You know it strikes me today what a great job you’ve done with packaging and serviceability on the car. It’s one thing to start with nothing and put things in place but on a vehicle that is constantly being tweaked, upgraded and re equipt it’s really impressive to see how nice and tight you’ve kept it.

 

The guys at Racepac are great. I was helping someone out with troubleshooting some odd issues... garbled and no data log, turned out the memory card that was being used was just old and had failed.

I ended up talking to one of Racepac's support gurus, there wasnt a single hesitation on helping out... Super cool and very helpful.

Where did you end up mounting the logger?

 

I have never had a data logger. This is very interesting and enjoy learning about this. Thanks .

 

I agree. The packaging Brian has done is great, no easy task to route and position all of this and still have access for easy service to be accomplished. Takes a lot of thought and planning I'm sure.

 

The race pack has to be mounted in a very specific way. It has a accelerometer built into it. It has to be mounted level. I have mine located on the cross bar behind the passengers seat area. The plug goes toward the front. Placing it at the height of the bottom of the windows works good. That was a good question.

 

The converter showed up. The Bruno and lenco are back in. We are on schedule for a fire up next weekend
