Went out in some not-so-great air in my n/a A6 5.0 last night...

[Five Oh Brian]

Congrats on the PB! I'm thinking that intake setup looks great and it obviously helped your car. As soon as Mike Rousch has your tune perfected, I might just follow in your footsteps.

Nice times! Do you know what your race weight was? I was thinking that in 460 DA air 118 trap seemed a little low, maybe your car is pretty heavy? Mine with basically just off road x and dyno tune minus passenger seat (loaded premium car) was trapping 115 in 2200 DA air, I would guess my race weight was about 3800. I thought the cobra jet guys were 120+ in good air

I agree, I was hoping for/expecting 120mph traps as well in that air. But my friends who were there had trap speeds that were a little 'off' compared to what they were expecting also so who knows. One of my friends has a new stock automatic C7Z and he ran 10.90s at 125 all day, and he trapped 127 a couple weeks ago in much worse air a couple weeks ago. My car was trapping 11mph slower than his on that day (when I had my stock intake) and on this last trip I was only 7mph slower than him. So I think I did pick up significant trap speed over my stock intake, I'd say a consistent 3mph. I'm going back next Friday to Cedar Falls Raceway to test it out again.

I haven't weighed my car. It's a base car, with only the front sway bar removed and the Racestars that I run at the track, and I pulled the spare tire out.

That's a good Improvement. Hope you get a new PB

good deal. Maybe the air was ok and their timing system had a glitch.

If you look at your incrementals, your MPH back half is roughly the same as before the CJ. 24MPH.

ET difference on the backhalf is:
CJ - 4.41
Stock - 4.25

The stock intake was run in worse air.

If the timers were moved out, your MPH and ET would be up. If they were moved closer both MPH and ET would be down. We aren't seeing that in the incrementals. I am not saying the timers weren't changed...just some food for thought.

Sticking a g-tech in the car and comparing data to the track clocks would be one way to know. Also, if you have a log to review that may help some too although MPH there will only be as accurate as the tire revs per mile data in the tune.

Are the shift points where they need to be? 7,500+ for each shift is the target.

Also, I don't think that GT500 TB is helping you. My car slowed down when using it and picked back up when I switched to the mono-blade.

The runs this past Saturday were from a totally different track, and without the strong tailwind I had on my previous outing at the other track, so not really apples to apples. My best run with the car ever with the stock manifold was at Rock Falls (where I was this past Saturday) and was an 11.66 at 116.16, in around 700'DA IIRC, I'll try and find the slip later. Typically the car had been running in the 11.70s at 115ish in that kind of air, the 11.66 was kind of a 'halo' run I guess.

Current 1-2 shift is right at 7000, the 2-3 is right at 7500. Hopefully Mike gets it closer to 7500 on the 1-2 shift in a revision.

The OEM GT500 TB came in the 'package' deal I bought with the manifold and the CAI. Used for $1000 total, I thought it was a good investment because I'm sure I could sell it for that if I decide to.

Edit:
I was looking at some other slips from my August 21st outing. Later on in the evening the tailwind died down and even though the DA got a little better (around 2000') the car slowed quite a bit.

At 8:09pm:
60' 1.620
330' 4.851
1/8 7.542
Mph 91.46
1000' 9.864
1/4 11.824
Mph 115.09


At 8:44pm:
60' 1.631
330' 4.890
1/8 7.595
Mph 91.07
1000' 9.927
1/4 11.895

It will never be apples to apples unless it is done on the same day at the same track. And even as you noted conditions throughout the day can change. Considering your worst runs posted here with the stock intake and CAI, your incrementals on the back half were:

Better ET and close to the same MPH as with the CJ.

FWIW the GT500 TB is just over $100 new from Tasca. It may be an $~90 part for sale used, like new.

If it were my car I would replace the TB with the mono-blade SCJ or sell that intake setup and stick a Boss intake on with the Airaid PJ CAI.

Thanks for your input wbt, seriously. Obviously your car runs well and you know what you're doing!

I'm going to run the rest of the season with what I've got now (only 5-6 weeks before the tracks close around here) and see how it goes, maybe make a couple changes over the winter.

Again, thank you!

nice upgrade- think the car is 60ing a lil soft for your set up- what does mike have the converter locking up at- this has nothing to do with your 60 I was just curious-
my car 60 foots decent but the 1/8 mile is a lil light but then makes up for it on the 2nd half- I still have never sent mike any data logs yet - I maybe road tripping to Maryland in late November to get a few glory passes in after I get my tune worked out , I have gone 11.48 at 118.6 with a 1.57 60 . I may make the switch to e-85 and just have mike send me a whole new tune and then dat log that and work the bugs out- good luck in the next few weeks

Mike's tune is currently locking the converter at around 6000rpm/58mph in 2nd. What DA did you run your 11.48/118.6 in? Our cars performances are VERY similar except like you said my 60' is a little off compared to yours even though the ET/mph are the same. I know each track can be slightly different. The best 60' it's ever done was a 1.61x I think. I've tried various launch techniques and it doesn't seem to matter too much. I think it will 60' better in good DA at the track in Iowa I occasionally run at (Cedar Falls Raceway).

 

[bunits19714]

my 48 pass was in da around 650 ish with better rear suspension than my 55 pass on my signature. that 55 on my sig, was in a - da but with the rear sway bar off the car and stock lowers and no relo brackets- I went 1,59's in the summer heat with my factory wheels and a 265/ 18" dr. - I was shocked on how lil et difference there was between my 275 60;s and the 18" dr- that was mid 11.60's in 1900 da this summer with the factory wheels back on. the car liked the shorter tire more than the 28" compared to 26.? - car would trap around 7k on the shorter 18"s- he has my converter locking up around the same- every tuner has their theory - a lot of quicker na car guys are locking theirs up right when the car hits 2nd gear - fast and hard- I may ask mike to bring mine down -

More testing this past Friday night. I was hoping for better DA and a new PB but it was a little 'unseasonably' warm around here this weekend. My ETs seem a little 'soft' for the 60' and MPH the car does, compared to my old 2011 car, same setup except for a Boss manifold and a 3.31 gear versus the 3.15s I still have in this car. I'm starting to think the gear helped my old car more than I thought.

Still had fun and the car is super consistent! Mike sent me a tune revision and it's now shifting at 7200 1-2 and 7550 on the 2-3.

 

[wbt]

A little better.....
[email protected] and 24.21

1-2 is still off. No reason that should be 7,200 by now.

IMO it is time to switch tuners. Make no other changes to the car and give Lund a shot.

 

[2011/5.0]

I would sent mike in a data log. I think its pretty common to need a few adjustments. When i ordered my tune from mike i was also running a tune from lund. After 3 logs they were both satisfied they tunes were safe and spot on

 

[KrisR]

So, winter's here, tracks are closed. Car will be hibernating for a bit.

I was thinking of trying out the VMP Twinjet 67mm TB on my setup. The tune I'm running from Mike Rousch is setup for the Ford Racing twin-65 TB (yes, with my OEM GT500 TB...it does not run very well at mid throttle settings), and from what I've read the Twinjet uses nearly identical TB settings, so it should run well.

Do you guys think I should try this, with my existing tuning/tuner, or just go for the monoblade and have Mike try and get it right, or give Lund a shot?

Also I might switch to a 3.31 gear, as my previous car with Boss manifold seemed to like it quite a bit, with my 27.2" drag radials. Or I could keep my 3.15s and go to a 275/50-15 which is slightly shorter.

I'm guessing that longtubes would be the next logical step, but for $1000+ installed they don't seem to make that much of a difference. Also the gains I've seen on other cars from a light driveshaft don't seem to make that worthwile.

I dunno. I want to get it deeper in the 11s next year. Thoughts?

I had even considered selling my CJ manifold and some other stuff and just sticking a Beefcake Special-type Vortech/Paxton kit on it. Hello low-10s? LOL. But I do not want to lose any reliability. I really enjoy driving the car to the track versus trailering it, even though I have a trailer. Also I drive the car A LOT ... 15k miles this past summer.

 

[kingcobra323]

Well my buddy just went from twin 67s to monoblade with no tuning changes. And he said car runs great. He will be running at track on Saturday. I'm running mikes tune and have hit a hump. Im stock mani, 3.15s, alum ds, e85, cj cams, kooks lt, airaid, 3c. Now I need more converter. I'm thinking boost next

If the timers were moved out, your MPH and ET would be up. If they were moved closer both MPH and ET would be down.

If the trap timers are further away from each other, it would indicate a lower trap speed as it would take additional time to trip them, right?

I've always figured that if the traps are set too far apart, your trap speeds will be slower than if the traps are set too close.

 

[skaarlaj]

Man you auto guys are simply tearing it up!! Is it feasible to swap a maual out for one of these autos or easier just to trade in for an auto car, lol!

I bet there are some disappointed people when you guys running times like this open your hoods at the track and the blower, or nitrous lines people are expecting simply aren't there.

Congrats on the times man!!
