5858 track times e85 Turbo TA

[dvernst]

11.22 @ 117.6 with a 1.48 60'

First pass I had a 1.59 60', and thought that would be my best all day. After that I had two 1.48's in a row launching at around 12 psi off the foot brake. I was able to get to 20 psi at the line although the tires couldn't handle it. I was hoping for more MPH, but I think I can still get a 10 second pass.

 

[KEVINS]

How much boost were you running? The MPH is kinda low for that ET...

[dvernst]

26-27 psi. I might need to go to a taller tire. Not sure yet. I just started tuning it, and I'm running extremely rich.

Mph is right on with the 60'. I have gone 11.3@115 with 1.50 60'. Nice job.

Thanks! I had some tuning help from Steve(BEATAV8). My converter slip is around 6-7% giving through the traps around 5200 rpms

Great job with the sock motor!
Have you changed the valve springs? A taller tire will give you a little more in the 1/4.
I have the PTC 9.5, it is an awesome street/strip converter!

Yes I did. I'll add it to the list
I'm definitely happy with the converter. It has a lot less slip than my single disc Precision lu

I like the fact you can spool so easily and still couple at that low rpm range of a stock cam. It's definitely a difficult application for a converter. Great job!

Yes it's definitely a small rpm range to work with. I was expecting more MPH with the less converter slip, but being too rich might be slowing it up a little.

 

[dvernst]

As far as tuning since I switched to e85 I literally had three 3rd gear pulls on a back road before the track, and that's it. I got 5 passes in at the track, with only 3 good ones. I'm pretty happy with everything so far

Great 60!
What blade PTC is your converter?

Idk. Maybe Dusty will Chime in again.

Idk. Maybe Dusty will Chime in again.

might be written on the box? I was wondering too. My blue car could use one like yours but maybe 200rpm tighter.

The TE44s and TA49s flow enough air for 120mph. I'm actually surprised not to see a little more mph with the boost you are running and the more efficient wheels. Great runs nonetheless though. Awesome ET for the mph. I go faster to go slower than you

The wheels aren't more efficient on a thermal basis but they do have the potential to move a higher mass flow. Not at the pressure ratios he's at though. Boost in the mid 30's with tall tires should net 10.70-10.80.

Do you guys think if I go to a taller tire my 60' will suffer?

 

[Lil Truck]

I run 275 60/15 28 inch, and get 1.54 60' on a good track. 11.32 @ 118.5 Stock suspension with drag shocks.

I would expect you to do as good or better!

It's most likely a 17.
