Thanks man. Looks like you're banging the gears better than me. How do you like your magnum?

Bore/stroke=4.185"x4.125". Limiter was set at 7500 but it had been so long since I had driven and I had never driven anything with that much power so I was on the limiter a total of 1.693 seconds in the video pass. I have put about 2000 street miles on it and I had never gone WOT. I had no idea it was going to pull like it did.

The headers are custom 2" to 2.125" with 3.5" Cone Engineering slip fit merge collectors . Tim (Gray86hatch) came down to GA and we had a header building weekend in my shop.

I just picked up the tires last week. Mickey Thompson 26x10 stiff wall. I was launching off the two step at 5500.

Next time out will be even better!

 

Congratulations!!! That thing is flying. Great job! That 60' tho!!! = )

 

Thanks! It has a lot more in it!

 

I like the Magnum but don't flog it as hard as you do yet. 1.28/1.29 60' is mind boggling. Those Fox bodies certainly hook! I assume the track was pretty well prepped?

I just noticed you gained 34mph in the back 1/8th mile. Dude... that is crazy. Guessing it is because you weren't on the limiter as much.

 

Wow! I was engrossed for the entire thread! Great build and it really runs out!

 

I don't know if it helped but I have done some unorthodox UCA relocating and as for track prep, I never saw them do any prep throughout the day but we didn't get there until after they started running.

I was looking at the datalog and yes, I was not on the limiter as much but the majority of the 34 mph back half is due to the forth gear pull. That top end is stout!

Don't need any wise-cracks about the limiter...I'm working on it. Should have driveshaft speed next time out.

 

Driveshaft data will be a big help.

 

I have the pickup wired and mounted on the diff. but eight magnet collar is on back order from Strange.

 

What is the part # I can check my source

 

Thanks.

 

u1617-8

 

Davis Racing Technologies sells parts that will work with the Holley.
Mine uses a 6 magnet setup mounted to the driveshaft yoke (had to bore out the 2 halfs to match up to the yoke diameter.

The Strange CM yoke has a 2.5" diameter lip for their collar. I haven't seen any others with 2.5" ID.

 

Is this the yoke you have

Hey, you know, those light weight aluminum clutches are supposed to short time like that. You're doing it all wrong...




Yes that was sarcasm.

 

Have you had to do much clutch tuning or has it been good out of the box?

Yeah, I've never been on board with that myth. Works pretty good for 26lbs total.

 

Before I put it in the car I set it up for the street and put 2k miles on it. I called Cale the week before I went to the track and he gave me base setting and counterweight as a starting point and told me to call him if I had questions or wanted to change anything. After I figure out the counterweight it takes 15-20 minutes to make the changes.

At the track, I was so impressed with the car, I only checked air gap one time. The clutch was too tight and wasn't working as intended but I was just trying to make a clean pass without getting on the limiter. That never happened. I have new adjustments to try next time out.

Btw, the alternator is charging between 13.8 and 14.4 volts.

 

Can you snap me a pic of where your harness comes into the engine bay and how you routed it to the motor, please
