2.5 pulley is slowing you down I bet. Many have tested and below 2.75 it gets too hot. Your coolant tank may help but I'd be curious what IATs are like.
I don’t agree on the 2.75 thing. A 2.75 and lower with is similar to the 2.55 is quite a bit faster. But yes need to combat heat. If I Remember right he has a chiller.

Looks like where my car is at the 8th, you must be getting real hot up top. Probably need more cooling mods, but if you have a chiller idk. Are you using good canned e85?

You didn't answer if it is spinning or just not leaving hard
1st gear spins. Second gear doesnt leave hard.

Op… what are you complaining about? You just posted 60’ literally all over the place… 1.7… 1.6… the 1/4 mph does seem a bit low, but honestly might need a driver mod
Not complaining. Seeking advice. Im sure a driver mod would be great. And im seeking advice on that.

Exactly why I asked about the mph and showed those time slips where I ran high 9’s (we are yet to see the time slip to do the math). Sixty ft isn’t just about hooking up. You also need to have the power to accelerate and if there’s a issue then it’s going to show up from the top of that time slip to the final mph. I don’t see where the 134 mph number was shown. That isn’t all that strong for a modded e85 motor unless the da is real high. I think there’s more going on than just traction.
Slips have been uploaded and my et mph is betwern 132 and 134

Sorry, just meant with the 60’ all over the place it’s hard to gauge where the issue is. Have do doubt you’ll get it dialed in, you’re in good hands

I hope so. I know i aint no pro at this. Also not a newb either. Just trying to get some advice from everyone on what to look for, whether is tune or car related or if i just need to be better

Not sure if I saw you mention it, but make sure you’re resetting your driving modes after using burn box. I didn’t once and the car spun and then fell on its face, log showed everything just decreasing over the 1/4 and was one of my slowest passes.

I ensure my settings have reset to my custom ones.

Side question, im usinga rtd on the tdn to datalog and send to jon. Likewise this is wjere he loads my tunes as well. My question is does anyone know how i personally can pull the log files and review them myself?

I don’t see anything on here about 1 step colder spark plugs and closing the gap 🤔

Even with a better 60’, it looks like you are not making enough power to get in the 9’s. Your 1/8th mile and 1/4 mile speeds are low compared to the ones MarcW posted in an earlier post. You need a better 60’ but maybe you just have lousy DA? Is your trans tuned for different shift points?

The only thing i know to do is wait until Jon reviews log files, unless someome knows a way for me to pull them and view them myself.

The DA on the 1/8 mile slips i uploaded from yestersay was 2200-2300
