The onset of Throttle Cut in all FATS runs with the IPP's while only two of the FATS runs with the Stockers could present an argument that the the IPP's had a lower pressure drop...read Flyboy's notes...included

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 (99 views)

Obviously all we can do is speculate since to measure those affects - Flyboy 2006-09-29 09:41:11 (107 views)

Hey, Jeff: When you have TC the DV's should stay closed. - Mike2kS4::ASP 2006-09-29 11:40:17 (87 views)

Thanks. That answers that question. - Flyboy 2006-09-29 15:32:51 (73 views)

Great job, but where are my APR RS4 IC hoses?? =) - box_of_partS4 2006-09-29 06:21:34 (84 views)

Well done. You were as thorough as you could possibly be without getting rediculous ;) - Mike2kS4::ASP 2006-09-29 05:21:06 (86 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 (116 views)

Out of curiosity I've made some similar logs. But it's a completely different - Flyboy 2006-09-29 10:44:40 (122 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 (98 views)

Agreed. Inconclusive data always begs a plethora of "what if's". - Mike2kS4::ASP 2006-09-29 05:18:51 (111 views)

Wow nice data collection and analysis. I do have one concern - 'Nova S4 (Greg) 2006-09-29 05:01:50 (135 views)

What conditions would you suggest trying to test for? The - Flyboy 2006-09-30 06:50:23 (91 views)

If conditions allow, 2 backtoback fats+ tests with heavy braking and as much boost as possible. - smurfbus4 2006-09-30 07:14:55 (90 views)

I'm not sure I understand... - LI-S4 2006-09-30 16:45:56 (82 views)

I think what he is suggesting is that there be essentially - Flyboy 2006-09-30 17:32:26 (98 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 (77 views)

He's trying a MBC. - Flyboy 2006-10-01 07:23:50 (81 views)

A 1st-4th run would be better, IMO.... Best done on a dragstrip ;) - Mike2kS4::ASP 2006-09-30 19:54:29 (70 views)

You know...a few people have been implying that the tests don't simulate conditions- -> - LI-S4 2006-09-30 18:17:51 (89 views)

Truth be told...Stockers are entirely sufficient for all but extreme conditions.. - LI-S4 2006-09-29 14:43:39 (105 views)

preeeeeeetty.. - BlackS4TT (Josh) 2006-09-28 23:45:01 (84 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 (170 views)

There are no real provisions for the shrouds on the IPP's- -> - LI-S4 2006-09-29 14:38:24 (101 views)

what i gathered from that isn't so much that IPP sucks - nyet 2006-09-28 23:46:00 (200 views)

It's all "relative".....suck compared to what? - LI-S4 2006-09-29 14:39:04 (76 views)

that is the $10,000 question ain't it :) - nyet 2006-09-29 14:47:52 (102 views)

I'd take the first bet...probably skip on the second.. - LI-S4 2006-09-29 14:55:35 (88 views)

I guess we'll find out soon enough when he compares those 2 to AWE/RS4. - PSmallsSmells 2006-09-28 23:50:22 (130 views)

we'll see - nyet 2006-09-28 23:51:22 (131 views)

Taking bets... - LI-S4 2006-09-29 14:39:49 (77 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 (87 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 (86 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 (121 views)

Great work on the tests - Phoenix80 2006-09-28 22:29:27 (77 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 (81 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 (87 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 (137 views)

As B5QShip notes...I see the FATS as inconclusive relative to HP.. - LI-S4 2006-09-29 14:30:01 (105 views)

Wrong. What part of "no faster FATS" is inconclusive? - rktskicar 2006-09-29 19:14:18 (102 views)

The part where throttle position drops to 40% halfway through the acceleration test. - Flyboy 2006-09-29 20:00:44 (99 views)

" so you can independently verify that I correctly identified the TC" ?? - LI-S4 2006-09-30 06:13:25 (89 views)

OK. Fair enough. How come stock IC's had TC? - rktskicar 2006-09-29 20:08:08 (99 views)

I logged 115 on a seperate set of logs, but only on the IPP's - LI-S4 2006-09-30 06:15:53 (91 views)

I was a bit surprised by that myself. A couple possibilities, - Flyboy 2006-09-29 20:39:53 (109 views)

There was most definitely TC occuring. Unfortunately LI-S4 had to use VAG-COM - Flyboy 2006-09-29 03:15:53 (123 views)

I would say the FATS tests are not very conclusive since there was throttle-cut - B5QShip | CFDQ 2006-09-28 21:35:15 (100 views)

I would like to see some log/plots with throttle position and boost to support this. - rktskicar 2006-09-28 21:57:37 (83 views)

me too. But without it I don't think you can conclude anything... - B5QShip | CFDQ 2006-09-28 22:00:27 (86 views)
