Tuning complete. Time for the track!

[Jay-rod427]

Finally got everything lined out and ready to rip the track tomorrow night and see what does or doesn't break. LOL. Hopefully all goes smooth and as expected and not picking up halfshaft pieces.

Jon Jr at Lund has done the tuning as I specifically requested him. Had to work through a little bit of false knock issue, Jon attributed it to blower noise/vibe being picked up since it was very intermittent and lowered the knock sensor sensitivity slightly. Works great now and knock sensors still very active.

Here is the latest street datalog. A bit of tire spin rolling into 2nd, and every shift thereafter. Traction control pulling timing down for a bit, and then limiting top end timing. Rolling into 3rd it throws full 22 or so degrees at it when traction control doesn't intervene. Got one more revision from this to get the 2-3 shift a little sooner. 8,000 and 16 lbs is a little much. LOL. Will have 1-2 data hopefully from the track.

That's exciting!

You have no idea how excited I am to give it a rip from a dig. Slow rolling into second is getting old! This should end up being the fastest car I've ever driven. Hoping to get into the 9's a bit.

How much whp are you guessing? What et/mph u shooting for?

Dunno 750-800 maybe.?.?. Man if it went out and went 9.80 @137-140 I'd be pumped. Tuning is pretty soft on the shifts to minimize breaking/spinning, and could up the shifts if need a little more power,but 14 lbs was my comfort zone. But realistically however/if it runs into the 9's I will slow it down to 10.0

My feelings exactly about my car. It's the fastest thing ive ever owned and seriously dangerous on the street going WOT. Keep her on the track lol.

Good times for you ahead, im sure. Congrats.

If it makes 800whp, it should trap 146ish. I'm going 141 on 700whp. Et will depend on prep, trans shift points etc.

Gotcha. Like I said no idea nor do I care about whp. How hard are you turning yours on pump gas? I can't remember have you done any suspension work?

I see 17 degrees on pump. I've found if the 6r80 shift points are conservative, car will slow down a bunch. Also my car 60fts quicker just going wide open from idle. Throttling up to say 2800 on the footbrake then going wide open slows the car down. Bmr080, proactions, vertical links, adj to links and cradle lockout is what I got.

Just saying since u are street tuned, the mph will give u an idea of whp.

Get that 2-step going and I bet 60' picks up a few numbers. No delay on the electronic throttle.

I honestly don't know if I'll get off the line worth a shit with zero suspension work done.... next on the wants list.

For sure. The shifts have torque reduction applied, but shifting at 7500 should make some decent steam. Hopefully E85 and more timing should yield half decent mph. Anything under 10.00 is a win for me as I don't want to cage it and all that crap yet. Low 1.50's 60', but run decent mph out the back would be ideal for me.

 

[Jay-rod427]

If you buy into MAF to hp approximation it maxes out at 7,200 rpm so figure 17% drivetrain loss 715 whp give or take. So 750 might be close. I'll prob dyno it at some point for kicks to correlate a datalog with output.

I def want to see if there is benefits to the 2step without transbrake. Hopefully there is!

Are you not turning the traction control completely off? I would think completely disabling it would not pull timing, even with traction loss? I would think your making 800rwhp easily.
