Well, here are my timeslips from CFest for all to analyzed. They are ordered by time-of-day left to right. On the first one I dusted the tires and did a soft launch off idle with TC on to get a feel for the track. Turns out that was the best time. It started cutting out at about the 1000' mark and I coasted in from there. It got progressively worse from there. Did a good burn out and launched at about 1500 with TC off. Got a little past the 1/8th point and it cut out so coasted from there. Third run I barely made it to the 1/8th, and well the last one I made it maybe 300'.

dude... i got a headache trying to read those! Would you hold still for gosh sakes!!! LOL!

That 1st run would have been low 12s with some descent air! DA was about 2500! (We had over 3000 here in Michigan on Saturday... I didn't race, but dang it was MUGGY!)

Yo, your eyes must be slow/old. I read them fine lol

12.5 is very commendable in the heat, plus with the issues you had.

Thanks. Getting tired of the excuses and want the car to run right. It's got 11s in it easy. Pulls much better with these turbos on it. Pulls hard all the way through the RPM range instead of the slow build up of the other turbos. I always loved 3rd gear in this car, now I plain love it.

Perhaps Black Friday at Atco in the cool air? Plenty time to get your car in order. Along with the rest of you FI guys it would be something to see.

Last one was awesome.

So many great 5th Gen cars there.

Nice run Derrick considering the DA. 2686 at 9:53 AM. I must have missed that run of yours. I was watching for the first hour or so.

Nice time.

I do see your Camaro in this photo thou.

Ok... time for some of my world famous RICER MATH!!!

Did the 1/8 to 1/4 ratio on your first run which had your best 1/4 ET. Then applied that ratio to your 3rd run which had your best 1/8th. That turned 12.897 into a 12.455.

DA at 11:30 was about 2690.... that turn the 12.455 into a 12 flat...

Hope you can get things figured out ASAP!!! Really wanting to see Gretchen live up to her full potential!

BTW, loved your commentary on your time slips!

3G - looks like some room for improvement - the potential in the car is there like John was saying - I just had a few questions...

What was 'cutting out'? Has Rx got the fuel issues more or less resolved? On these runs, what was your boost levels and what is the highest boost level you can achieve w/o using the methanol injection- if its even possible for you to use high boost w/o meth?

Thanks, David

Were fine to 5-6# and it is above that we run into the issues. Adding a 2 bar MAP and redoing the tune and that should take care of most of the issues.

I was running 8 psi (the lowest I can go with the springs they have in the turbos). First and last runs were with no meth.

Not sure exactly what is going on. Obviously it got progressively worse. On the dyno we only pulled WOT in one gear. So it maybe something related to the adaptives in the ECU. It seems we have the fuel at the HPFP, but maybe the in-tank pump can't keep up now or the adaptives are undoing what Vince has changed. Maybe he's not finding all the tables that need to be tweaked. Either way, I just need to log it at the track to figure out exactly what is going on. I don't like doing that at the same time I'm driving, but they wouldn't allow ride alongs this weekend. This may take a while to figure out, so just be patient everyone. As always, I'll share what I learn so you guys can take advantage of it.

I know how you feel man, you know your car is very capable of it but there is just one thing or another that is holding you back. Sitting here with this OD pulley making 10 psi of boost and knowing that my car is capable of doing so much more is just downright frustrating.
