Okay, some good and some bad news. I'll start with the good news.

Rhino got the transmission back in last night and we did some pulls on the street this morning to check it out. It felt good and it looked like he was getting the higher pressure he wanted. Temps were staying with in normal range.

So we packed up and drove to the track and met up with the ZR1, two supercharged SSs, a 5.0 and Bobby Shahan and one of his beast Gen 1s.

Rhino logged the first couple of pulls and fixed an issue with the 1-2 shift. The car was trapping a couple of MPH below what we were expecting and way higher ETs than we thought. Our old friend the throttle position wasn't solved after all.

Horrible 60's and just felt dead up to about 35-40 MPH. The it would take off like a rocket. After a few more pulls and another tweak to the shifting Bobby suggested we just skip the burnout and not even clean the slicks off. The idea being that the reason we aren't seeing this the street is we are spinning so bad the car thinks it is going that fast. So, Rhino hopped in to log and we pulled the first sub 1.8 60' ever in this car and trapped 117 MPH for the 1000 ft.

That run was launching at 1800 RPM and Bobby suggested we just launch from idle to give it a better chance to spin up. 60' dropped to 2.0x.

After all that we had run out of time so I made one more pull and got the same result. I'm trapping within a couple of MPH as the two SSs, but they are running about .4 faster.

Long story short, still more work do. It's trapping about where I think it should and it pulls real well on the big end. We just have to sort out the launch. I'm out of ideas right now, but not giving up.

Awesome job! That's all good news. The car is still in one piece. what were the 1/8 mile times? 117 in a 1000' is still damn fast

Best 1000 ft was a 9.1x. Unfortunately my best 1/8th was a 7.2 when it really should be around 6.8. Trapping just a bit faster in the 1/8 th than I did at Memphis, so all the gains were on the big end.

That's still amazing. that's a 10 second quarter for sure especially since you said the power is at the top end. congrats!

I agree...it is amazing! By my quick estimate, your run of 117 in the 1000' and 1/8 @ 7.2 puts you at a high 10 or low 11 and maybe better.

Damn that is so awesome.

Do you have anything on this...video or slips or anything?

Just curious, but what was the ZR1 running and what mods did it have?

Pssh I say just throw it on a 1/4 mile track, collect your 10 second slip and be done with it. Sounds like a killer street machine which I personally prefer anyway. The throttle issue will likely never come up on the street and it must be so much fun on the street since you power is on the big end

Yeah, the GPI video guy took some video. I will link to it when he posts it.

I will post some slips tomorrow.

Zr1 has a mild cam and 100 shot. He doesn't want his times posted, though.

Good times were had today...that's for sure. I got a pb 1kft of 8.71@119 on a 1.56 60'.
D, that freaking 6cyl moves out. I agree, let it make a full quarter with the boost up. I think it for sure has a high 10 in it as it sat today. If you want to try my drag radials instead we can work that out. I'm rolling the forgestars back on it ASAP. Probably won't see track until we all go burn the 1/4 down in LA in the late winter/early sping.

Probably because it was so fast the slip showed a negative time. Time Warp!

Thank - yo ufor the news. Good luck getting it sorted out. Can't wait to hear how it does once that is done and out on the 1/4 mile. All from a baby V6.........very impressive.

Yeah, you were hauling the groceries on those last couple of passes (pun intended). May take you up on the drag radials, however, I am probably going to take a break for a while. Work is going to be real busy for the next couple of months, so I won't have another chance at the track. I am looking forward to a trip to No Problem for sure. I can up the boost and make up some time on the big end. I was seeing 10.5-10.9 AFRs all day so she's still running pretty fat for a DI car.

I'm a little disappointed we didn't actually fix the issue...really had my hopes up. However, I am very happy with the car. It runs great on the street and most of the way down the track . It also has more power at the twist of a knob and push of a few buttons. So I'm pretty sure 10s are in the bag, just don't know how deep I can go right now. For now I am just going to enjoy driving it for a while and see what we can come up with. I think getting the launch RPMs right will be part of the solutions, it will just take some practice. Ultimately we want to get around this nanny feature in the ECU though.

Julio at AlkyControl built us a box based on MAF frequency.

Here are the four slips I could find. I am not sure what happened to the others, but I will keep looking for them.

Here's some analysis I did. The top part of the spreadsheet are all the Power Adder/Stock Displacement cars running about what I think mine would run in the 1/4th (10.99-10.80). The bottom section are the four slips from above. I highlighted in yellow the metrics where my average is quite a bit below the average of the cars I'm comparing to. Green is where I am doing better than their average. As you can see I'm really pouring it on after the 1/8th. In fact, I'm running about 13 feet per second faster than their average between the 1/8th and 1000' mark; almost as fast as they are moving between the 1000' and 1/4th.

Now that's what you call back halving it.
