    small update,
    exhaust is finished and on the car
    IMG_4913.JPG

    IMG_4912.JPG


    ran into an issue which will keep the car from being ready this week. damn. oil drain doesnt fit properly with the ewg port there. this is where the progress has stopped. not sure what to do here
    IMG_4921.JPG

    my buddy had come up with the idea to modify the drain, and just run some hose in between. i guess this will work ok right? what other options do i have? keep in mind, this car sees serious heat on track and i need reliability. i think a hose shouldnt see much heat where it would be between turbo drain and block but im not sure. any advice or input?

    temp solution for oil drain, need to get some better hose, i have oil rated and temp rated hose coming from vibrant, should be in today and i will get it swapped in. also have some DEI heat sleeve coming, will cover the line with it and it should be good to go and reliable enough for track duty.

    dump tube is done for my EWG

    installed

    WG has been installed and was a MAJOR pain in the ass. hopefully it doesnt need to come out anytime soon. hoping to have the car finished this weekend and boosting by monday. then itll be time to tune it and see if any power is gained on this new setup. or ideally less boost to make the same power i had. also hopefully its not too loud!

    WG dump is a little close to the power steering lines even though we tried to make it not so close. will pick up some more DEI product to make some shielding, ill wrap the dump tube, and even the PS lines. should be ok for now. really just want to drive the car again, even on a base map itll be plenty of fun

    Keep an eye on that hose for the first couple of hundred miles. Even with heat sleeves and titanium wrap, that is still a lot of heat concentrated into one area. If that oil return starts to leak, even a small leak will gush like a main artery. "I seen't it."

    You asked for suggestions earlier.... either go back to IWG which I know is not your goal, or get a manifold with an EWG port and dump the EWG tube downward.

    Having the WG off the turbo hotside, still forces all the exhaust through the flange first before the WG controls it. A WG off the manifold allows WG control before it goes through the turbo.

    Your WG setup now is better than an IWG due to size, but regarding flow it's kind of the same thing.

    hm, thanks for the input. i really didnt consider that. Im hoping this EWG setup is better then IWG, im hoping itll do for my longer term goals as well. the cost of going with a manifold and EWG AND new housing for the turbo was more then i was willing to spend right now, being in canada i get KILLED by exchange rate, shipping, and duties.

    so speaking with my buddy who built the dump tube yesterday, he said theres decent clearance between it and the PS lines so thats a good plus!

    im hoping this fancy vibrant tubing and the DEI heat sleeve will hold, ill check it out over the first few weeks, but i know on track heat is WAY more then on the streets. i may have to run a hot lap, then inspect it and see. heres hoping!

    well, cars done. my buddy and i finished it on monday. monday was a holiday here in canada land so we took the day to finish it up.

    it fought us a bit but over all we won. first issue was the oil drain, the new hose i got was stiff and hard to work with given how short the piece was, but we got it in there, heat sleeved, and alls well there.

    hose is rated to 300f, oil resistant, nylon sleeved, stainless steel reinforced. DEI sleeve is rated to 2000f radiant heat. should be ok since its not touching anything(hopefully)
    IMG_4938.JPG

    i did drain all the coolant so i used this as a good time to refill with some fresh stuff. simple process, took a little but of time but no issue there.

    next annoying issue was oil feed, it was leaking pretty good. i had new OEM washers for the bango but it was still leaking, tried tightening it, still leaking. my buddy remembered there being a stainless steel washer ontop of the fitting, so we removed the copper washer and put the old stainless washer back in, problem solved! no more leak.

    first start was extremely rowdy. car is loud. cold start is TOO loud. can cold start be tuned out? i know theres a way to bypass it but anytime ive tried it it doesnt work. warm idle isnt too loud at all so thats good.

    initial drive was terrifying. 15psi spring combo in the gate, EBCS bypassed, it hit 19psi followed by a loud BANG then the car started dying, and i freaked out. blew a charge pipe. limped back to the shop, fixed that. round two, alls well. still saw 19psi though. I emailed my tuner and he responded back saying 19psi is fine, a little creep but nothing major, i offered to lower the spring but he said its not needed so thats good!

    one thing i am going to do is replace all my vac line for the WG and ebcs. im using this tiny ID cobb stuff, 3mm ID, tial recommends no less then 1/4" ID vac line(6mm) so i ordered some to replace that before we start tuning.

    car made it over 1 hour home, highway driving and back roads. no issue. drove well, exhaust is a little loud on the highway but its manageable. the EWG screamer though, thats loud. very loud. too loud for the streets but a non issue on track. cant wait to get the tune dialed in and finally hit the track again!


    dump pipe, good bit of room around it, shouldnt have heat issues, still considering wrapping it. thoughts?

    back in town finally!

    I wouldn't worry about heat wrapping it, now that it's installed. I'm going to do my dump and DP once I start this S5 install. I say if you notice significant warming by your feet on track, it may be worth it then.

    Yea I think it should be ok. There’s decent room around it. Spent the weekend driving the car around. Ran some new vac line, went all 1/4” for the WG and EBCS. So far, even on just a base map the car feels great. It’s creeping to about 19psi with the 15psi springs but my tuner said that’s fine so I’ll leave the springs that are in it. Top end feels strong.

    EWG is a ton of fun for sure, but damn is it loud lol. My exhaust is also far too loud with just that one muffler. Need another muffler for sure! Can’t wait to get the tune dialed in again and hit the track June 8th!
    [doublepost=1558958740][/doublepost]friday i swapped out my corolla for my speed, and shook it down a little around my buddies shop before i decided to go home. my buddy came along for the ride

    lost a charge pipe, thats always terrifying, but good thing i had tools!
    IMG_4959.JPG


    Cold start is too rowdy, and the exhaust overall is too loud for me, going to be adding a muffler, a proper high flow 3" muffler.



    little fly by of some EWG action,


    new 1/4" barbs and vac lines for EBCS
    IMG_4966.JPG


    Took a log this weekend, everything looks good, boost comes on later and is a little lazy but im assuming thats cause my wgdc is all zero'd out, and slightly larger exhaust housing. with some wgdc added back into the bottom end im sure itll spool quickly again. vdyno showed 304whp, 313wtq corrected, so thats decent i guess, for 19psi anyways. shouldnt have any issue hitting the mid 300's im after. Top end feels strong, cant wait to finish up the tune again.


    also, not sure if this is because i did a drain and fill on the coolant, or because of the newly installed oil cooler, but my coolant temps have been keeping lower then im used to, by a decent amount too. i wonder if thatll show on track also.

    Its very possible its helping depending on its location. What oil cooler did you install (specs/brand) and do you have any pics?

    ive got a few pictures my buddy took and sent to me, theyre not great but youll get the idea,
    oil cooler is a mishimoto 19 row, with a setrab thermostatic sandwich plate. its right above my front mount, its in front of my rad, so with my track day coming up soon ill see how it helps with on track coolant temps. oil temp/pressure gauge will hopefully be going in soon as well.

    Should have my car back friday, finally, for good lol. Had to add a muffler, the near straight pipe exhaust was just too damn loud for me. maybe im getting old or what but it was too much!

    had my buddy add a nice magnaflow for me. he says it sounds good now, still makes noise, but its not ignorant anymore so thats good!

    cars done, just cant get up to the shop to pick it up until friday after work. ah well, its going to be a really nice weekend, so ill be logging a new map, and giving the car a good solid shake down after all these changes. make sure everything is solid enough for track duty.

    i need an exhaust tip ive been told....low on the list of needs right now lol but ill get one.

    have some nice heat sleeve coming in for my vac lines, had a WG line crack due to heat last year, that was some scary stuff, not looking to deal with that again.

    also, this is where the car sits power wise on the new base map, took this log before i dropped the car off to have the muffler added. this is corrected for the temp and baro that day.

    creeps to 20psi, slow spool(my guess cause of the 0 WGDC and lower timing) but over all feels good.

    That's honestly a fat powerband for being on spring pressure and base map timing! Now to shift everything up a hair!

    Picked up my car friday after work and immediately flashed my new map to it, i wasnt expecting much as this was just to test boost control with the new ewg but i wanted it on asap.

    Left my buddies shop and went to go wot, didnt go so well. Car was stuttering and popping, back firing, and cutting out at any boost above 9psi. that sucked. Flashed back my base map but same issue.

    turned out to be my spark plugs, one spark plug hole was full of water! i guess the coil wasnt seating properly with the seal and the car sat outside in the rain all week. crazy, but new plugs gapped to 0.024 and we were good to go!

    plug change behind my buddies shop(not the buddy who does my exhaust work)
    IMG_4984.JPG


    quick look at the new muffler and exhaust on a lift, i like it alot. car is pretty quiet, my buddies think its too quiet and whatnot but i dont care, its PERFECT for me, no drone at all, its great, and with the ewg dump tube, i have noise on demand with that thing.
    IMG_4989.JPG

    last but not least, a little fly by with ebcs working, can hear that boost control working


    new map feels solid, both me and the GF agree the car feels faster then it did on the old setup, even with less boost, and even though vdyno shows less power, car still feels great and pulls harder up top. pretty happy with where its at and on track itll be great. turbo spool feels pretty damn good, response is awesome.

    numbers dont look like much but it sure feels good on the back roads, time to do some more tuning and turn the power up

    Well, finally took the car for a shake down on the streets, cant push to hard but i got a good idea! Went to visit some of the twisty back roads to really test it all out. Im on brand new hankook RS4, 255/40/17 tires and at first they were a little greasy, i was told this would be the case because of the mold release they use. after about 250km of working them, and some real heat, they seemed to pick up grip significantly.

    Brakes are HP+ all around, and stop tech rotors, slotted upfront, blanks in the rear. Car stopped without much issue but you can tell on these tight back roads that heavy car is heavy. Even around 310whp it was building speed at an incredible rate between turns. Brakes got a real work out, got them cooking. New alignment seems to be pretty bang on, lift off over steer and rotation under braking is very noticeable in low speed corners, hopefully it wont be too sketchy in high speed corners.

    my tune is still far from complete, only one revision since the base map but i can tell the top end is night and day since doing the ewg housing and 3" turbo back. revving out is actually rewarding, and going WOT in 3rd at 4k rpm, just about instant full boost. Feels very responsive which is what im looking for for my uses.

    Over all, car felt strong, handled well, and the EWG dump sounds amazing. cant wait for track days.


    a picture of the car all cleaned up

    cruised with my buddies on saturday,
    IMG_5020.JPG







    little compressed crap quality footage of some nice EWG sending
    (gf recorded for snapchat then saved it = poo quality)

    can really feel the grip of the front camber and the RS4's working. can really feel yourself being thrown around the car. need to install my sparco seat i think.




    well this is it for now, im super happy with where the car is at, how it pulls, and how power comes on! in a straight line its kinda meh but i didnt build for straight line so im ok with that!
