In Reply to: Wasn't the TC in all the IPP/RS4 FATS runs indicative of a lower pressure drop than the stock- -> posted by LI-S4 on 2006-10-21 05:25:28

to you using the MBC to cap boost, which was not the case for the previous tests with the stock & IPP IC's.

But yes, I considered the occurences of TC an indication that the pressure drop through the IPP's was probably less than the stock IC's.

Excellent work in this analysis, just adding my input and assistance if requested... - scalbert 2006-10-20 18:09:22 (101 views)

I should also note that the factory thermistors are at best 2% units... - scalbert 2006-10-20 20:02:03 (74 views)

Do you know if other, faster responding thermistors are available? - nt2old4ns4 2006-10-21 10:29:35 (34 views)

I know there are less insulated thermistors out there... - scalbert 2006-10-21 19:13:27 (36 views)

I totally agree here. The temp drop differences are very small: - Toy_Guy 2006-10-21 04:44:54 (73 views)

Actually, if the ECU controls boost based on MAF... - scalbert 2006-10-21 05:43:26 (73 views)

steal one of Eric's IPPs. He won't notice anyway with his boost leak. :P - quickaudi 2006-10-20 20:32:28 (66 views)

It's all Jeff's fault. He made me do it. ;-) - LI-S4 2006-10-20 17:05:58 (41 views)

Good point. Some idea can be inferred from the data though. - nt2old4ns4 2006-10-20 14:10:07 (77 views)

Nice, Michael. Simple RS4's are quite impressive. Doing AWE's soon? - Mike2kS4::ASP 2006-10-20 12:28:20 (69 views)

Thanks Mike...but as I have stated..I was just the laborer. Jeff did the data crunching. (editted) - LI-S4 2006-10-20 12:59:54 (118 views)

Well, major props to Jeff too ;) - Mike2kS4::ASP 2006-10-20 16:07:14 (49 views)

Curious...Did IPP say anything about the tests you performed.... I for one wish I would of waited - s4florida 2006-10-20 12:28:12 (173 views)

..as I did. There's often too much hype and not enough data on AW. Have to be careful. - Swank4 2006-10-20 13:37:05 (66 views)

Are you sure about that? I believe everything I read here and don't know why anybody wouldn't. - STG3S4 2006-10-20 14:14:03 (49 views)

lol was the rs4 better? sorry i assumed. - brizax 2006-10-20 12:16:39 (78 views)

Wow...you ASSUMED the IPP's would outperform the RS4's? Interesting... - LI-S4 2006-10-20 12:21:17 (81 views)

ipp = stock oem? - brizax 2006-10-20 12:18:03 (91 views)

Basically. - Mike2kS4::ASP 2006-10-20 12:30:05 (67 views)

then what could account for the avg 25hp dyno gain that 3 cars put down after uprading to ipp's? - faiz_nogaro w/drawal 2006-10-20 13:37:32 (125 views)

Better pressure drop across the IPP IC vs stock most likely. We saw this - Flyboy 2006-10-20 20:02:30 (126 views)

Ok, email me some before/after logs. - Mike2kS4::ASP 2006-10-20 20:10:14 (73 views)

quite optimistic, but they are stage 3 cars. Is LI-S4 stage 3? I didn't think that he was. - quickaudi 2006-10-20 14:01:57 (85 views)

Stage 3- (APR v5.0 93 code / Piggies / Custom cat back / X1 Intake) - LI-S4 2006-10-21 05:22:23 (47 views)

a stage 2+ made the same gains....if u search the forums u will see a link with the dyno sheet - faiz_nogaro w/drawal 2006-10-20 15:07:28 (70 views)

wait, a car with K03s with made a 25 hp increase and so did a car with K04s? that just sounds silly - quickaudi 2006-10-20 20:34:35 (66 views)

here u go silly ;-) .....see link - faiz_nogaro w/drawal 2006-10-20 20:46:41 (88 views)

aha! I figured it out. - quickaudi 2006-10-20 20:54:37 (85 views)

less pressure loss than stock? - davenew 2006-10-20 13:57:35 (63 views)
