Good luck Chris. Looking forward to hearing how you do this year.

I am confident all your hard work will pay off.

Good Luck Chris......


I know you have worked extremely hard to get to this point...... A 200MPH run would cap things off wonderfully.

Good luck and Godspeed!  We await the successful report.

I'll look forward to hearing how the event went.
Best of luck to you!

Thanks guys!   

We got thru tech with no issues, pit area set up, and the drivers meeting is in a few minutes.   Feels good to feel ready this time!

Hell yeah!

I figure by the end on Sunday we'll have one of three outcomes:
1. A 200 mph time slip
2. A busted engine - hopefully a head gasket vice a rod or crank!
3. At some point the engine just won't make any more power despite increasing the nitrous load - this "street" head just may not be able to flow enough to be able to use that much nitrous

No matter how it turns out - we'll have a much higher starting point for next year!

Headed out to the airport now - if the rain holds off we may have a fairly cool day!

Chris,

Obviously, I hope it's #1, but either way, it's been fun watching your progress with this.
Good luck!

Well, 2 runs down.  First was a bit slow - tune was a bit fat and lazy on the timing (especially for the race fuel) and I was short shifting a little.   135 for the first run. 

Took about 4% fuel out at WOT across the board and added 1 degree of timing. Speed now 144.  That gets me the B license.   Now time to swap the rear sprocket for a 35 and pull the baffle out of the pipe.   This will be a 59 shot of nitrous all in on the shift to second.

I don't understand 90% of the stuff you talk about on this thread.  But THIS one item I do.  Very impressive.  Good luck on the 200mph goal.

Thanks!

It's cool having people stop by the pits and talk about their old FJ stories.  Steep learning curve but we keep on climbing.  Tweaked the tune for the 100 HP nitrous shot for the last run of the day - 187.7 mph!

We are starting with a 125 HP shot tomorrow.  Hopefully will be a bit cooler tomorrow and we'll get rid of the darn head winds.  Winds were bad enough the really fast bikes (220+ !!) weren't running. 

Here's hoping 50 more HP from the nitrous plus a bit of tuning will get us 13 mph or more!! 

The big hurdle we had to get across today to get us out of the 150s was to finally figure out the FJ tach was lying to us BADLY at higher RPMs and to simply ignore it and rely totally on the shift light.  He'll of a leap of faith to make!  We were running 18/35 gears today - put the 19 tooth on the front tonight along with the 125 HP nitrous jet.   

Pics and videos to follow - just finished up the tune for tomorrow and time to get to bed - we start early tomorrow!

That's bad ass.
