finally made some passes with my 472

Post  BigRigTech on August 15th 2014, 11:34 pm

Took my new 472/fresh rollerized C6 with Merkl t-brake VB to the track tonight. First pass was a 2000rpm foot brake shake down, spun off the line and it was hard on the limiter at the big end - 10.37 at 133.91mph with a 1.50 60ft. We put put a 6800 pill in the box, dropped the slicks down one PSI and left on the trans brake on the next pass with 3000rpm in the two step - 10.25 at 132mph with a 1.45 60ft. The next pass was the same as the second, no changes and it went 10.28 at 135mph with another 1.45 60ft. All new personal bests. The car is working great, pulls hard and straight for junky old SSM bars Wink . The only thing I notice now is that it heats up a lot faster than it used too wether idling or making passes. If I hit the burnout box at 150-160F I'm pulling into the pits around 210F with the fan and water pump both on. No changes to the cooling system from last year. I'm running 11.4:1 compression with AV100 for fuel. Timing is set at 38*. This engine made 560hp/560ftlbs on the dyno with some windage issues (had to put 10L in it to stop it from sucking air between the pick up and pump - that has been corrected since) I have 7.5L of oil in the pan now and it runs with no issues at the big end.

Big Bracket bash tomorrow, $14,000 in prize money which I won't see any off...LOL...I'm going to run both box and no box tomorrow to get lots of runs in. I'm still a mess at the tree and it's worse now with me trying to get into a transbrake/delay box routine - but that will come with some seat time. The car has dropped 4 tenths from my old personal best so I'm not complaining because there is more to be found yet... Very Happy

Have you played w/timing any? Try 36* just for shitts and giggles and see if picks up. Very Happy  Glad you got back too track. Wink

The timing was too far ahead when I checked it this morning so I reset it to 38* as it was on the dyno. Just went 10.34 at 133mph, it was 200F when I got back to the trailer so that's back to normal. Still trying to get my routine down with the transbrake and delay box, my work at the tree isn't very pretty so far LOL

I'm with Rick...38* seems like a lot of timing.  Even if a little less timing doesn't make it faster, you won't be so close to the edge of your tuning window and it may live a little longer.  Tune it to repeat...that means get the carb dead-on so it's less sensitive to air quality changes.   Running a personal best e.t. at a bracket race gets you beat.  Save those for tnt days.    

Nice runs, tho.  Glad to hear it's running well.   cheers Yeah, the delay box routine takes a little practice but it'll pay off.  Those lotsa laps you're about to make will show huge improvement.

Coming to the pits at 200* after a 1/4 mi. pass is no sweat.  I wish I could do that. I stage at 160* and pit at 200* after a 1/8 mi. pass, but it's hotter than the hubs of hell down here and the nose of my car is completely closed off.  I use plain water with a bottle of WaterWetter and it helps...even with my tiny radiator.

Go git 'em at the big race...and don't go in assuming you'll lose.  My chances of winning seem to improve when I convince myself the other guy is a duck.  Wink And nobody wins a big race without some luck.....especially me.

Be sure to report after the dust settles.

The 2nd time trial was a 10.36 at 129.75 in the other lane so it's consistant which makes it easier to dial. 97 cars in the no box race. In the lanes now with a 10.33 on the window, overcast now.

I ended up going out in the buy back round of the no box race and in the 3rd round of the box race on a self inflicted tree butcher job LOL..all in all a good day and the car is working great so that is all I wanted to see. Try again to master the tree in the morning !

Congratulations on the next PB I know what you talking about on the transbrake my reaction time is off with the TB not sure if it me eyes doing or just late letting go of the button. I got eye surgery the 25th so after my eye heals I see if it me being slow or it was my eyes. Rolling Eyes  Good luck tomorrow.

I'm running one of Franks vb's and I'm finding I have to raise the rpm to about 2000 before I push the button otherwise I get a 2-3" nudge when I mash the throttle. Doing that while staging and then trying to remember to let go of the button on the top bulb is all new to me this weekend. I was cutting .750 lights in the no box race trying to go off the bottom yellow. I need seat time to work on my routine and get my crap together at the tree because the car is doing it's thing just fine. On a good note I found out last night that 1faststang made it to the final 4 yesterday with a .500 light in the semi but went 9.63 on a 9.61 dial to just miss out on some money. He was in the lanes behind me when I lost in rd 3. First place in no box paid $4700 and first in box paid $4200. Then they paid like another $500 got the "king of the hill" between the two winners.  Very Happy

That little "rock" you get when you set the brake is pretty common...not just with Frank's brake. It's difficult for the pump to load reverse quickly enough to suit us when we're staging a car. As you know, raising rpm helps, as does waiting a bit longer before you release the footbrake. We don't always have that little bit of extra time, tho, do we? Mad

So far today I cut a .620 and a .584 light so in going in the right direction LOL. I was one car away from the burnout box and it took to a light rain shower so now we are waiting for it to dry up. This is a temporary track at an air strip, no fancy track prep gear here. I have another mustang in the other lane dial 10.44 and I had a 10.37 in the window so it's pretty much a heads up race coming up.

We got rained out. I was one car away from the burnout box when the sky opened up again. They cancelled it an hour later. Oh well, got 11 runs in and had a great time. I could not be happier with the way the car is working. I put 8 clean runs in my weather station so that was good too. The DA was around 2000ft all weekend with 75% humidity. The track is 325ft above sea level.

We had a great time. It's been a rough year in my house with both the wife and I being diagnosed with health issues so it was nice to have something go right for once. The car worked very well - better than I expected considering all the changes.
