I finally managed to get a couple decent passes in tonight since the TCI3500 to Yank PT4000 swap.

Previous best was 11.96 @ 112.42 1.642 60'


First pass, forgot to open the cutout, doh!

60' - 1.634
1/8 - 7.544
MPH - 90.29
1/4 - 11.889
MPH - 113.13

Second pass, opened the cutout, but spun slightly:

60' - 1.641
1/8 - 7.522
MPH - 90.57
1/4 - 11.84
MPH - 113.64

The next 2 passes got progressively worse as the track went away due to the hundreds of street tire cars. Spun pretty bad.

I've got a SSRA on the way, we'll see if I get eek onto the SI list and maybe see some 115 traps next time.

I'm going for the list on Sunday. My preliminary 1/8 results are looking good. I ran a 7.571@89.74 with a 1.684 60' having to roll into the throttle to keep from spinning.

I'm gonna bring the DRs with me on Sunday, so hooking shouldn't be a problem. Not to mention this track should be better than the 1/8 that I ran on last weekend.


How we're you launching your PT4000? I've heard some conflicting stories about stalling and flashing. What worked best for you?

What seems to work for me with my VERY limited practice time is holding the RPMs at maybe 1500 or so and flashing the converter. It hits hard, I'm not hooking well though.

Congrats! I wish tracks were still open around here for the winter....You will get in the SI list, hopefully I will as well. Looks like that new stall is working.

Picked up a little MPH as it should, good job. I am going tomorrow, hopefully the track hooks.

Where is the SI list? Shooting for that myself with lots of work planned next Saturday but have to wait a long while for a track visit.


What mods do each of you have and weight?

What is the definition of "SI" since what I read here some see it different ways?

Anything that touches oil?

- Roller rockers
- Valve springs
- Intake?

Those would make it ineligible?

what are you guys shifting your pt4000's at? both of you are running the stock cam, right?

MikeG

iTrader: (33)

Intakes don't touch oil, you can change those. My car has the stock ls6 intake, never been off the car. Can't change the rockers or valve springs though.

Mine shifts at 6200. Stock cam, yes.

These cars have a dry valley, no oil touches the intake manifold. Basically valvetrain is what it refers to.

I have your same exact list except 3600 stall and a ported TB. I am putting 1.85's on so I guess there goes my bid for SI

Also 6200 with stock cam. I shifted at 6200 before the converter and the car liked it.

Didn't get on the SI list, but I'm gonna lose some weight try again next week.

Went a bit quicker again tonight. Those who say the SSRA doesn't work can kiss my ***. 1.63 11.70 115.66. Still couldn't hook for **** though .
