We had a total of 5 passes on 9/11. We played with Torque Converter lockup, timing and even lowering the shift points. The best we got was my standard shiftpoints, and 2 degrees of lower timing. The best run was #4 as 12.333 and 113.42MPH. All runs were made on the new Nitto 555R's at 20 psi.

It is still having shifting issues. When it shifts (or attempts to) from 1st to 2nd, it kinda hangs and tops off at 6300RPMs and when it shifts, it feels as if it is slipping. then it hits 2nd and let the tires loose and BAM, it shifts into 3rd. No matter what Andre does, it always short shift and basiclly skips 2nd gear. So Andre is going to pass the tune file over to SCT to see if the guys there can determine the oddities it is having.

Take comfort in the fact the the 15+ Neons and 15+ GTO (some stock and some modded) could not even touch the times of the 05 with a S/C. And when I say modded, I mean bigger turbos for the Neons and head / cams for the GTOs.

Dang Bro,
I knew I should have headed that way Sunday.
I would love to see your car run down the track.
I also need to get mine back at take a few passes to see what it will do now. Only had it at the track in stock form.
Let me know next time you head that way and I will see if I can make it.
Nice runs and it should only get better when you work everything out and the weather get cooler.

I will say, the 15+ Neons and 15+ GTO (stock and moddifed) - so take comfort in that boys. A S/C 05 beat the heck out of stock and modded Neos and GTO's
Hrm? That doesn't make any sense to me.

Nice runs though, darn I wish my car was that fast...

Brain,
Was the 405 dyno number @ 6 psi or 8psi (your sig is confusing me , Just want to confirm the numbers, when do you expect to up the boost to 9 psi? I want to see if you are going to be able to get the 470 RWHP that Procharger is claiming their kit puts out.

By the way nice times, can't wait to join you

405 is at 6psi. I though it was 8, but during our runs down the track we are only getting 6psi. Also, remember, I am an auto tranny so my numbers will be less. I am waikting on the pulley until I have solid track times. Until I get my shiftinf fixed, I would not like to upgrade and cause more issues, such as the MAF maxing out.

So, once the tranny issue is resolved, I will get the 9-10# pulley installed.

Just one note, I dynoed at 405 rwhp and it ran like poo. The next day, Andre, sent me 2 new tunes that added some timing down below and removed som eup to. This made a HUGE difference. I would guess at the moment, I am at 430rwhp +/- 5rwhp I am basing it on SOTP and the G-Timer

Brain,
Thanks for clarifying. So it would appear that the 470 is a realistic number (VERY COOL)

So many mods so little money... :bang:
