2018 Royal Crimson F1A94 Procharged, TH400 Drag Project

[80FoxCoupe]

We finna find out!

Prep for dyno complete:

Oil change, once over the engine bay, burn out in the street in front of the house, hour long variable speed drive with a couple pulls with traction control on, emptied the catch can, swapped the sticky tires over to stockers for the rollers, and loaded the truck with gear.

What spark plugs? Gap?

What spark plugs? Gap?

I put plugs in back in march, they have a couple hundred miles on them. I run ngk 6510s at 0.024. I have a brand new set with me just in case.

Gap that other set at .020.

Left work for an hour to pick up a trailer and some straps:

After work, I test fit the car on the trailer. I'm storing it in the garage overnight:

Put in One Ethanol R:

Loaded a tune that has the gear indicator turned on:

Ready to go:

Hey all, today has been a long day. I'm home now and the car is in the garage. I'd like to formulate a more official and thoughtful response that you all are owed. I don't want to put too much pageantry in this, but will ask you to hang with me a bit to give me a chance to type it out on chronological order with pics and videos. I appreciate you all rooting for me. Cheers for the night.

Fingers crossed that nothing major broke. It’s been a long process and I want to see more videos of you in the car going down the strip!

Thank you to Joe Devito, Steven Kiehne, Aaron Miller, Rob Shoemaker, @80FoxCoupe , @Jay-rod427 , and a bunch more. I appreciate you all a lot! The garage build put in the work. This factory fresh, unopened engine and trans (and converter) held it's shit together and is ready for the next part of this mission, an 8 second slip.

We got the car loaded up at 6:30a and we were on the road!

Arrived 90 mins later at the dyno and strung it up:

Took one last shot of the engine bay before making pulls:

I have more to share and videos. Sorry to break it up like this, but I am just out of time to do it how I'd like. Hang in there. Back to my day job to pay for all of this. View attachment 494925 View attachment 494930 View attachment 494931 View attachment 494933

Thanks for waiting, it was a 13 hour day at work for me catching up from being off yesterday. Let's get to it!

All pulls were done in 6th gear vs 7th (1:1) to reduce the impact on the trans.

After the car was loaded up, I contacted Rob and PBD letting him know we where ready. He gave the green light for a 6th gear pull, 2500 - 6000 on the existing loaded tune. The car impressed me right out of the gate, making good power

The second pull was 6th gear 2500 - 7500.

Tune revision. Third pull was 6th gear 2500 - 8000.

Started to see a big break up at 7400 - 7600 rpm elapsing .5 secs. We suspected spark blow out. Ran another pull to see.

Tune revision. 4th pull, 6th gear 2500 - 8000.

After confirming the break up, we changed out to new plugs gapped at 0.018

After the plug change, we had an aborted run due to bad misfire and break up. I pulled the plugs to see if they all fired. Put it back together. Ran again. Aborted again, same issue. Keep in mind we're trying to solve the 7400 - 7600 dip in the graph. After the second aborted run, I pulled all the coils and inspected the pins. Found two with slightly bent pins. I have the 15-17 MSD 2 step on there which requires you to remove the pin alignment pieces making it easy to bend the pins. That's what happened. Fixed the pins and tried again.

7th run, 6th gear 2500 - 8000.

The dip wasn't fixed, but the bad break up from the 5th and 6th run was solved. I received a tune revision from PBD, but I didn't load it and instead reviewed the logs myself and found the fuel pressure was dropping 20 psi between 7400 and 7600. I let Rob know and we decided to direct wire the fuel pumps and remove the hobbs switch.

Run 8. 6th gear, 2500 - 8000. Dip was solved.

Tune revision titled "X" for final. 6th gear, 2500 - 8000.

SAE final:

STD final:

There was a lot of down time waiting on tune revisions. The plug change and investigation took forever. It ended up being on the dyno from 9am until 2:30p. At one point we put on the afr wideband on the tailpipe but it came loose fell on the dyno drum and shot out the back. That was exciting.

I'm very happy with 1030+whp (corrected) on a completely factory fresh, unopened engine and trans. I think it'll have just enough to get into the high to mid 8's if I catch a lucky day.

Thanks for being patient with me. Thanks for the support.

Have a watch if you'd like:

Damm I missed it by 43 ..... and no pop .... nice numbers

 

[Chris Barnes]

Very impressive. Scary that you are the one that noticed the fuel pressure drop though! Great build and great job as I know you've done the majority of the work on the car yourself. Can't wait to see what she runs!

 

[SolarFlare]

great numbers. You guys log boost?
