Man that sucks to hear. I'm sure you'll get it figured out though. I'm curious what circle d says about how that convertor is working. Sure seems like it should flash a lot higher than that.

With all the timing that was being pulled out the engine produced less torque than a stock V6, so it will flash the TC a lot lower. For reference, at the Rally in the Valley event my timing was 22 degrees at launch, last night it was 9 degrees. Gears will have lowered the stall a little but not by half. I'm going to get the timing issue fixed first before I call them, I think it is the tune still. On the street I can get the timing to run at 22 degrees but last night it was just pulling way too much timing because the wait in the staging lanes, and I think it was unnecessary.

On the last run the video I noticed the camera shook at launch and that is when it stalled to 2700, the boost was only 1 PSI. That is the G5 run which had the 1.8 60' time. It will take some time but I will get it figured out. This year is turning out just like the last 2 though, struggling throughout the year and then at the last track day I break my goal by over half a second.

Screw it, I'm installing the 3.33" pulley. Lets see what her pistons look like.

Those are still nice runs.

Really was hoping for this being the 11 sec weekend! Really suggest 3800-4000 stall for this to put you right in the sweet spot!

It was a little disappointing but there still is a learning curve for myself and tuning. The stall is a 4000 stall, but if the torque isn't there it won't stall correctly. It was also extremely hot, one ZL1 owner runs 100% methanol and he said his IAT's were over 183 degrees at the big end, the heat was murder on Friday night.

I'm also wondering if there is a failsafe for the MAF if it is overloaded and does stuff to the timing that isn't reported by ECU to the laptop. Going to switch back to the draw-thru and see what happens. Also going to contact HP Tuners about the TCC not locking at the directed MPH, might be a bug in their software, see what they say.

Just found this thread. We did a 245mm 5C which is usually around a 4000 flash rpm at around 400 hp and similar torque. Are you sure this is the flash rpm and not the footbrake rpm? Like you said this is a learning curve for all of us as we mostly work with the v8 cars, and keep in mind you get a free stall change within a year. We can loosen the converter with the "E" stator. That may help you out

Thanks, if I can't get it to flash correctly I will probably have you guys look at it. Right now I think it can flash to 3800-4000 if I get the timing right down low, too much was being pulled Friday night. Also, the footbrake RPM was 2400 RPM, when I launched straight from that it flashed to 2700 but was actually at a lower timing than when I had my foot on the brake.

I attached 2 screenshots from my datalogs on Friday. Top one is when I held the brake and brought the RPM's up, then launched it (G5 on the timeslips). Bottom one is when I had my foot off the brake and just floored it hard when the light turn green (G7 on the timeslips). When the car shifts it actually flashes to 1100 RPM at 5500 RPM's, after being shifted from 7200 RPM's.

If I remember right, it took a look of tune tweaking to finally make a stall work right on etmx183's car.

MPT said it would take several logs to get my wife's Mustang V6 correct and they are the best. I've gotten it to flash 3000 on the street before the tires smoked, so I think it can stall even higher.

Got the 3.33" pulley installed last night, gotta start her up now and see what happens.

MagnumForceGB · 07-25-2015, 06:59 PM

Just took the 3.33" pulley for a test drive, it is about a 1.5 PSI increase over the 3.48" pulley, so 1 PSI per 0.1" decrease. I also changed the cam timing even so that may have lowered it, but the overlap was the same. Timing was running more than before at WOT, and only Cylinder #3 registered 0.7 degrees of knock.

Was blazing hot, over 100 degrees so the car didn't have that much power. Going to drive it this week to see if I can get the fuel trims smoothed out and see how it feels. The gatorback belt seems like it is quieter than the gates one though.

I used the gatorback too. Much better imho

Do you know the part # for the stock (IPF) set up?

sorry to jack thread.

sycraft · 07-25-2015, 11:07 PM

061075 or 061073 but that was the lfx motor. Look on your belt for the number
