When the car momentarily ceases to produce power, and then throws a charge pressure exceeded code, then limps into tht next run...I'd call that throttle cut..

Nice work Mike and Jeff. But, what other effects does TC have on these tests? (more) - CASA *S4* KING 2006-09-29 06:52:48 (97 views)

Hey, Jeff: When you have TC the DV's should stay closed. - Mike2kS4::ASP 2006-09-29 11:40:17 (84 views)

Thanks. That answers that question. - Flyboy 2006-09-29 15:32:51 (70 views)

Great job, but where are my APR RS4 IC hoses?? =) - box_of_partS4 2006-09-29 06:21:34 (80 views)

Well done. You were as thorough as you could possibly be without getting rediculous ;) - Mike2kS4::ASP 2006-09-29 05:21:06 (82 views)

Thx for the data. I think you need to talk Jeff into being the test vehicle as hes probably at peak - Hal_S4Shizzle::CBP 2006-09-29 05:09:18 (112 views)

...you just dont want to take your car apart =-) Sounds reasonable. The end tanks on the stockers - Hal_S4Shizzle::CBP 2006-09-29 12:39:59 (94 views)

Agreed. Inconclusive data always begs a plethora of "what if's". - Mike2kS4::ASP 2006-09-29 05:18:51 (106 views)

Wow nice data collection and analysis. I do have one concern - 'Nova S4 (Greg) 2006-09-29 05:01:50 (132 views)

What conditions would you suggest trying to test for? The - Flyboy 2006-09-30 06:50:23 (87 views)

If conditions allow, 2 backtoback fats+ tests with heavy braking and as much boost as possible. - smurfbus4 2006-09-30 07:14:55 (85 views)

I'm not sure I understand... - LI-S4 2006-09-30 16:45:56 (79 views)

I think what he is suggesting is that there be essentially - Flyboy 2006-09-30 17:32:26 (93 views)

I really am fine with your setup. Are you using a TCD to avoid TC or MBC? - smurfbus4 2006-09-30 22:43:39 (74 views)

He's trying a MBC. - Flyboy 2006-10-01 07:23:50 (76 views)

A 1st-4th run would be better, IMO.... Best done on a dragstrip ;) - Mike2kS4::ASP 2006-09-30 19:54:29 (66 views)

Truth be told...Stockers are entirely sufficient for all but extreme conditions.. - LI-S4 2006-09-29 14:43:39 (101 views)

preeeeeeetty.. - BlackS4TT (Josh) 2006-09-28 23:45:01 (81 views)

Thanks to you and Jeff for all the effort on this! It seems like IPP and stock suck equally.... - PSmallsSmells 2006-09-28 23:40:34 (168 views)

There are no real provisions for the shrouds on the IPP's- -> - LI-S4 2006-09-29 14:38:24 (98 views)

what i gathered from that isn't so much that IPP sucks - nyet 2006-09-28 23:46:00 (196 views)

It's all "relative".....suck compared to what? - LI-S4 2006-09-29 14:39:04 (72 views)

that is the $10,000 question ain't it :) - nyet 2006-09-29 14:47:52 (98 views)

I'd take the first bet...probably skip on the second.. - LI-S4 2006-09-29 14:55:35 (84 views)

I guess we'll find out soon enough when he compares those 2 to AWE/RS4. - PSmallsSmells 2006-09-28 23:50:22 (127 views)

we'll see - nyet 2006-09-28 23:51:22 (128 views)

Taking bets... - LI-S4 2006-09-29 14:39:49 (73 views)

Yep, stock is efficient in low boost low speed tests so I dont think any other IC will shine either. - smurfbus4 2006-09-29 01:18:25 (83 views)

HOLY COW - nyet 2006-09-28 23:02:21 (142 views)

<scratches head> Must study and read... :) - reefer_bob 2006-09-28 22:52:49 (80 views)

thanks LI-S4 and fly, waiting for that rs4 test. Anyone willing to test these on stg3 air flow ; ) - smurfbus4 2006-09-28 22:43:21 (81 views)

3 minus is as close as I can get right now..and, the AWE's I hope to test..../ - LI-S4 2006-09-29 14:36:32 (116 views)

Great work on the tests - Phoenix80 2006-09-28 22:29:27 (73 views)

I think you should submit this to some academic journal =p Thanks for all your efforts!!! - B5QShip | CFDQ 2006-09-28 21:36:29 (76 views)

maybe I should submit my fist into your face...either that or submit your IPPs into your car. - Farbs | CFDQ 2006-09-28 21:37:47 (83 views)

I take no credit for the data analysis...wish I could- -> - LI-S4 2006-09-29 14:34:44 (81 views)

From what I can see, Stock vs IPP Intercoolers is same for FATS test. Is this correct? - rktskicar 2006-09-28 21:20:35 (133 views)

As B5QShip notes...I see the FATS as inconclusive relative to HP.. - LI-S4 2006-09-29 14:30:01 (100 views)

Wrong. What part of "no faster FATS" is inconclusive? - rktskicar 2006-09-29 19:14:18 (97 views)

The part where throttle position drops to 40% halfway through the acceleration test. - Flyboy 2006-09-29 20:00:44 (95 views)

" so you can independently verify that I correctly identified the TC" ?? - LI-S4 2006-09-30 06:13:25 (86 views)

OK. Fair enough. How come stock IC's had TC? - rktskicar 2006-09-29 20:08:08 (96 views)

I logged 115 on a seperate set of logs, but only on the IPP's - LI-S4 2006-09-30 06:15:53 (87 views)

I was a bit surprised by that myself. A couple possibilities, - Flyboy 2006-09-29 20:39:53 (107 views)

There was most definitely TC occuring. Unfortunately LI-S4 had to use VAG-COM - Flyboy 2006-09-29 03:15:53 (121 views)

I would say the FATS tests are not very conclusive since there was throttle-cut - B5QShip | CFDQ 2006-09-28 21:35:15 (94 views)

I would like to see some log/plots with throttle position and boost to support this. - rktskicar 2006-09-28 21:57:37 (79 views)

me too. But without it I don't think you can conclude anything... - B5QShip | CFDQ 2006-09-28 22:00:27 (82 views)
