That was a fantastic run. Especially when you dialed in @ 11.9. You must have smiled like you were laid by a super model when you got your time slip.

You used 100% meth and what is the additive?

Wow. That's about 20 psi then. I'm assuming u have 15ohm resistors ??

Before I could get my timeslip my friend had texted me 11.7 and I thought he was just joking, then I got the slip and was surprised. The only bad part was that It was the first round of eliminations and I broke out. I was looking forward to racing a bunch of American cars and had finally got the track tech to let me run with them instead of the imports.

Yes I do have 15ohm resistors. On a 70 additive it usually starts at 20psi and tapers down to around 16 or 17.

I hoping to match your time of 11.7 I'm FBO with jb4 w/ww kit 80/20 meth/water. I'll be using VP ms109 gas running 70 additive.
I did some logs 93 oct w/oct booster 60 additive the other day
Max boost 19.5 tapered to 15.5 at at 6200 rpm's
I'm gonna bump it up to 70 w/race gas and lower boost in 2nd gear to help w/traction.
Nice time,
I hope to see you in the 11's

Hope you have slicks or DR's, because 11.7 won't happen on street tires.

IIRC Terry (or Mike) has said that adding 15ohms will only allow for 1-1.5 psi above the 18ohm 17.5 psi threshold. Map 3 targets about 12.3psi + the boost additive up to the threshold of whatever you are running. Running peak 20psi may not be possible despite attempting to target it, but the higher the additive, the higher your psi will be near redline as boost won't tapper off as much. I could be wrong though.

O/P any logs showing peak psi? I'm curious as well.

Sure. Check out the regional TN thread or you can join us on facebook (Tennessee e90post car club). We usually meet the 1st Sat of every month in Nashville and we meet up some Friday nights in Clarksville at the drag strip. Shoot me a PM if your ever in TN. I was in Huntsville last week and stop by Trackmasters for a few dyno pulls.

was this the same issue that ended up being a relatively easy fix? Thought it wasn't a spun rod bearing?

I logged it to make sure everything looked okay before I raced but I didn't save the logs. If I have time tomorrow I will log it again and post it for you.

Thanks, I'm sure your logs will only convince me more to finally do the 15ohm upgrade

Yup I had to do it after I kept seeing my boost taper to 14 at redline even with meth and racegas. Get with terry, he'll do it for you for a great price if you just mail him the board.
