Swapped out the street shoes for the racing shoes. Taking the car up to work with me today and took Saturday off for the event. Working days this hitch, so I hope to head over to Noble Friday evening. Weather forecast is looking favorable. Lows in the 50's with highs in the 70's.

Car looks great! Go get 'em!

Nice! Kick some a$$.

Looks great! Let'er rip!

I'm gonna give it hell. Super curious to see how well this converter will couple and what slip rate will be. The 2 tests I did at the house were promising but the track will tell the tale. Expect a few calls on Saturday Brad

I'll be here working on the stairs. Can you get a couple practice runs in to check how it spools? Semi Pro or Pro Tree?

Time trials, you can run as much as you want during this time, then they group you according to closest times. This year, if you when your group race, you keep racing other winners in your group till there's a winner of the group. Kind of not competitive because your group may have 12.5 to 10 second cars in it. Maybe they'll do it bracket style so we don't have so many sandbaggers.
Last time I was here it was sportsman tree but the time before that it was a pro tree. Who knows
-
I just looked at the event details and they have changed. No more racing in the group to make a group winner. Instead they are paying out to closest ET in the group to their qualifying run. Guess that may eliminate some sandbagging but I doubt it.

Jason...go out and figure out what RPM the car likes to launch at. If you have to stay as close to your ET as possible...the n this is what I recommend. There's money on the line...so these guys will likely fuck with you in the other lane...they won't let you spool...they'll 'bump' in an inch at a time...blah blah blah.
A soon as you get the wave...do your burn out as quick as possible...and fully stage the car quickly. When they prestage...bri ng the revs up to around 1500 to 1600. When they fully stage bring your revs up to your predetermined RPM and hold it there. We have the old lites at my track...so I wait till the final yellow starts going dim...and then jump on it. You 'll have to figure the lites out.
Bring 2 old towels with you. Put them over the rear tires between rounds. The sun will bring the tire pressure up and give a false reading. I overinflate my front tires to around 50 PSI to lessen rolling resistance.

It turned out to be a beautiful day. Made 8 passes at the event with one being for the competition, but mostly test passes for me. Working a new tune with a new converter wasn't the easiest for me. Let's just say I'm not pleased with the converter under WOT. Slip rate came in at 11.63. I may be paying for Dusty to spec me one out. MPH and ET were slower. As always, it was good at the track. Nothing broke and got to see some friends.
-
Jason...one of the parameters that Dusty uses for building his convertors is boost pressure. Get a number you're comfortable with racing with at the track before calling him. Thank him for me for posting on TB.COM. He dumbed it down so morons like me could understand it...and he took the time to answer my dumbass questions.

No time slips? Or at least a hint at what it ran?
I saw Ken was a little off what he wanted but said track was good .
-
That looks like a lot of fun! Sure beats shoveling snow. :cheers:

Jason, I've been going over Erics SD2 vid. I understand what he's doing...and it's a crapload of work...and time consuming. I have a PL file you told me about...and I'm gonna tweak it to learn.
SD2 is for someone that loves to tinker. For someone like myself it wouldn't gain me anything...oth er than a full out max boost run with the MAF being removed to remove a restriction. I already know how far I can push my fueling. SD2 is interesting... to say the least. I'm definitely gonna be going over SD2 files.

Made 8 passes. 11.7 being the fastest at 116 mph.

Since you don't drive the car on the street, you'd be tuning for that very narrow rpm band. You do have to tinker quite a bit but nothing like the xfi software. It's a not a whole different animal but it does have it's idiosyncrasies that need to be learned that don't cross over from SD2 to XFI
-
The WOT part is easiest. It's coming up on RPM to WOT that's the trickiest and time consuming. I can see how guys blow shit up. I have the advantage of knowing where from a fueling standpoint my engine makes peak HP. Rewind a few weeks ago. With a big temp/humidity change I had to completely retune my car. Two adjustment runs and the car went 7.1x in first round eliminations.. .and I wasn't pushing the car and that was on an easy 1.8 launch on 23 PSI on a fat tune. SD2 is really cool...but when I hit the track I'm there to race...not to tinker. One practice pass...make my fueling adjustments... and it's on. You're a smart guy...and given time you'll be just as quick making adjustments with SD2 for tuning.
-
Nothing wrong with that. Real salty for a street car with ac.
-
I think the SD1 was better than the 2. Kept things relatively simple but gave a lot of possible tweaks. After initial playing, there are only about five things that I adjust. The 2 was for the nerd market that thinks you have to be able to adjust like an aftermarket system. I quit the nerd market a few years ago :D
-
When a 10 flat car with a 5.7 chip won't go any faster with XFI tuned by one of the very best...then that's all I need to know. Looking at the underhood of my car is a sure fire cure for insomnia...and I'm good with that.
-
I remember the 9.5 car that was guaranteed to go two tenths faster and it took a year before it went any faster...tuned by the best. I also remember all the 11-12 second cars that never went faster as well. there is a difference between marketing and measured performance. People seem to refuse to learn from history.
The funny thing is that we often have someone tell us that you can sell your old stuff and basically pay for the new, but, they never mention the cost of professional tuning and dyno time that comes afterward...we be preaching to the choir! LOL There is always someone that thinks it will solve his problems and give him the performance he thinks he should have.
