That's some serious heat between the dp's & cats.

my insperation really came from you but i wanted to see if i could put the electric valve on it and - bertworks 2006-04-19 12:17:54 (346 views)

how did you make the piece that goes from the end of the DP to the cutout? Custom? - S4=Lunch 2006-04-19 10:50:31 (240 views)

i just have gutted stock downpipes going into the 2.5" cutout pipe, then to my stock cats. - bertworks 2006-04-19 11:03:01 (227 views)

so, 2.0" cutouts, 2.25" or 2.5"? :) TIA! - S4=Lunch 2006-04-19 11:12:02 (187 views)

I run a DMH cut-out after the cat, in place of a cat-back system. Flows better, and quiet for work. - S4KTS 2006-04-19 10:37:46 (248 views)

Tracking...... Hmm I can put those where my test pipes lie or I can - 1bads4::WMS 2006-04-19 10:14:13 (267 views)

Very nice! Maybe you should think about wrapping the motors w/ some thermal tape for longevity.... - 5lugnuts 2006-04-19 10:11:07 (245 views)

Therm wrap would just keep conducted heat in - You'd stand them off like IM spacers if anything. - Superflex 2006-10-11 15:56:32 (139 views)

im not too worried about that since i dont keep them open for very long periods of time. - bertworks 2006-04-19 11:13:44 (223 views)

big thanks to DMH PERFORMANCE for the awesome cutouts. - bertworks 2006-04-19 10:10:43 (212 views)

Very nice work, would be interested in the results - Milpitas2.7T 2006-04-19 10:10:20 (163 views)

i am going to sacramento raceway soon and will post my results from the track, i also did some gtech - bertworks 2006-04-19 10:15:34 (269 views)

how will they be actuated? Switch? RPM? It'd be interesting to see them open at 4k or so. - 'Nova S4 (Greg) 2006-04-19 10:07:37 (219 views)

just a switch to open and close. i need to dyno them to see if im losing any low end torque with - bertworks 2006-04-19 10:18:45 (284 views)

you will not lose any power at all ever with them open - Snow Trooper@ToonerX 2006-04-19 10:23:39 (371 views)

well these cutouts eliminate almost all back pressure. - bertworks 2006-04-19 10:39:16 (196 views)

well there you go then.... - Snow Trooper@ToonerX 2006-04-19 10:43:09 (218 views)

i was just thinking of how some high end sports cars like the new z06 or the ferrari f-430 have - bertworks 2006-04-19 10:52:36 (347 views)

yeah, you will never lose power on a turbo car by eliminating back pressure post-turbine. - mjtaylor 2006-04-19 13:31:38 (234 views)

I'm in that camp and have always been, but I've seen heard of loss of low end torque - Milpitas2.7T 2006-04-19 14:26:45 (238 views)

That type setup didn't hurt MarkP's numbers. - Flyboy 2006-04-19 17:49:45 (433 views)

Yup. Turbos run on pressure differential...you want high pressure in and low pressure out - box_of_partS4 2006-04-19 10:26:54 (246 views)

agreed, my question was more about if there's a sudden pressure drop what that would do - 'Nova S4 (Greg) 2006-04-19 10:43:50 (210 views)

only positive effects - Snow Trooper@ToonerX 2006-04-19 10:48:43 (147 views)

looks loud. nice work though. - BiturboBoy_V2.0_S3-- 2006-04-19 10:00:29 (162 views)

wicked...how does it sound? - L0rd of the Rings 2006-04-19 09:56:07 (167 views)

nice work, sir. I think thats the first *clean* implementation of actuated dumps i've seen - B5QShip 2006-04-19 09:52:41 (169 views)

2nd. That a very nice looking setup. - WindyCityS4 2006-04-19 09:56:15 (157 views)
