I footbrake the car until 6.45 seconds, then hit the transbrake. I left around 7.8 seconds. When I hit high gear, the car felt like it shook the tires quite a bit for maybe half of high gear. Not sure if this is normal? lol

Anyone have any insight? Much appreciated. Thanks!

SBF, powerglide, chance converter, ladderbars, 33 x 10.5W tire.

60' was a pathetic 1.27

Looks almost like it was breaking up ignition wise. Can you back the boost down to say 18-20 psi and try to make a clean pass?

The TPS Sensor is moving around too. Did you lift? If not it may be loose.

It does look like you are breaking up or you have a miss.

What does your intake look like? Also is the main power for both the Fast and the MSD directly on the battery?

I lifted slightly after the power came on.

It's possible I have a miss, though I had a pass or two earlier in the night at that boost level without it breaking up. I have had issues with an old setup with plugs wearing with use and the gaps getting large enough that eventually it will misfire. I'll yank the plugs and check them out. They are NGK R5671A-10 straight out of the box. These probably have 10 passes on them.

The intake manifold is an edelbrock super victor, ported by TEA. Is there something specific you are asking about? The main power for both MSD (7530 box) and the FAST (classic sequential individual cylinder control box) are connected to the battery.

No biggie, I have seen weird distribution issues with some sheetmetal tunnel ram setups.

Im no where near as fast as you. With that said Ive found that when using cold NGKs like you , i could only get 8-12 passes on them depending on the tune. A fat tune would kill them in the 8 pass range and show a jagged RPM line. Not as jagged or aggressive as yours but i could see when they had enough on the log.

I use the NGK 10's. I have one set that I use to warm up the car and another set that I use to race. The warm up plugs are SHIT. They are all fouled out and nasty. The race plugs last a while but I change them often to reduce the risk of them fouling out. I only run the plugs about 5 passes or so and then I make the race plugs the new warm up set. I gap them at .025".
