slim floss type toothpicks, zip ties work best for TMIC fin straightening. toothpick gives the correct spacing between fins. and zip ties to make it evenly spaced all the way to the back of the TMIC. Soak in tub of water, slosh it around, drain out. tape the holes up, pour gasoline inside . slosh it around, drain all dirty oil sitting inside (because no AOS = blow-by oil goes into TMIC). Soak in water again, drain. this is a good way to clean the TMIC.
Snorkus delete was the first thing i did to my forester xt. Inplace of the void went a 3.5'' velocity stack that fits the airbox opening snug and sucks air from the right fender. Block off the other hole left from the snorkus - happy days. Helps a little bit with the turbo spool up while hearing it and the BPV when comming off the throttle.
great video ive had a 2009 wrx for a while now and im glad you brought up the headers at the end. im a tool and die maker so using die grinders is much of my trade i work in. so porting is right up my alley. good to know the stock ones are good to high power levels.
25kg of that sound deadening is pretty crazy. Nothing puts a smile on your face like some weight reduction! Response everywhere. Thanks for the video, mate! Reuben
Great video! Love your content. What is your opinion on air/oil separators, do they do more harm than good? Maybe you can talk about them in a future video? Cheers from Sweden.
@@racedynamix with this aos video, if you can talk about the one way ball valve under the induction butterfly. it works by vacuum/pres but whats the point? thanks, keep up the good work!
Regarding the throttle body coolant bypass: (1) if you want to run an aftermarket water temp gauge (some Subarus just have a "to hot/too cold" light) the throttle body coolant hoses can be rerouted through a small fitting that holds a coolant temperature sensor. (2) Since you have dug that far to get to the throttle, why not take it off and give the upstream side some porting to smooth off that aluminium lip. Just don't mess with the gap between the closed throttle butterfly and the point it nearly touches on the inside of the throttle body.
Nice video keep them coming. Few things, remove spare wheel and jack and replace with foam can, save 19kg. When brakes new changing, replace with two piece discs instead of one piece, they save around 2kg per disc. 👍
Great idea re spare wheel. Most with upgraded brakes won't be able to use a spare wheel anyway as it won't fit over them. Yeah to the discs.. Much lighter 😎
@@racedynamix foam puncture repair is totally $hit. You'll end up calling road side assistance and realise what a dik you were for taking the spare out.
TGV are an absolute nightmare in my experience....100% ditch those out of the car. I can't wait for mine be replaced for some Sti stacks soon. The amount of issues that system has given me in the past year is horrible.
Buy some heat shielding gold tape and cover the left side of the intercooler. When standing in traffic or standing still after going fast the intercooler heatsoaks allot less!!! Massive difference as normally you cannot touch the top mount. If you have it off also do the exposed underside bits (not the fins ofcourse)
@@racedynamix yes works pretty well. Noticed it got so hot I couldn’t even touch the top mount after some spirited driving. After this it would be fine. Was running a bigger STI intercooler on my Forester STI which extended over the turbo heat shield so decided to give it a go.
Yes it should do. If you look at the bottom of the inlet manifold on either side there will be a mechanism or sensor. If neither and just flat metal then it doesn't 👍
Thanks for the Sunday video! So if I go and remove the tgv' and Port my headers.. Would it be recommended to retune? Just did get a tune and the guy is far away 😂🙈
@@racedynamix haha great. Think this will me the way to go.. Or really start with logging and than understanding before doing changes by myself. Get it on a diet this winter and see how confident I feel in the spring 😉 thx again. Have a nice Sunday
Do you recommend doing a matching grind to the heads that you do to the headers? On the ej205's i have apart i see the carbon ring is about the same on the heads and the headers.
The downside is some more noise and vibration. If you stick to areas which don't directly impact the cabin then it is minimal. Aftermarket stuff is just as heavy tbh but easy to add back if noise is a problem 👍
Hi Duncan, just wondering if its worth putting a harvey trick up pipe on my wrx wagon? Currently got a Haywood and Scott Up Pipe mated to Fastline TD04 Hybrid. Thanks
Hi Pedro.. It would be worth getting it checked. Helping the air out of the engine will probably change the fuel mixture. Best to batch this together with some other mods before your next map adjustment 👍
Ported stock oem headers for 500 + hp have you got any videos/dyno runs was always told 500+ needs aftermarket and preferably trick up pipe ? Currently re-shelling my hawk sti and going forged with gtx3071r from fastline ? Will ported stock headers make 500hp ? Or am i better off with fuji/rcm ?? Will be coming to you for mapping
Most I have made on std ported is 594bhp. Admittedly most at that power level succumb to the shiney gt spec but the std outlast them (gt spec are prone to cracking) and spool fabulous.
@@racedynamix thats my only concern with paying nearly £1000 for aftermarket headers heard nothing but stories of them lasting few years before they crack especially heat wrapped, well i already have my stock headers got nothing to loose porting them and seeing what they make 🤷🏻♂️ if im not happy with the figures supposed i could go aftermarket and get a map tweak or add meth 🤣 would you recommend a harvey up pipe with oem ported headers ?
Almost every blown subaru engine ive seen had a CAI in it, other than the massive turbo, oil starvation being other secondary causes. even if the ecu adjusts the air-fuel ratio properly, the physical presence of more air volume is still being mixed 🌪. This causes more heat in the engine 🌡(fire theory: a lighter needs oxygen to give a flame 🔥). Premature piston ringland cracks, spun rod bearings, head gaskets, etc.. CAI is usually used for Racing where the engines burn more air and fuel, wear out in few events, and gets rebuilt a few times. CAI used in daily cars leads to that end result eventually. Stock air intake is where the reliability is. A engine running a little rich has a slight effect on cooling. Other models may be able to tolerate lean conditions better due to their architecture and physics. but subaru is finicky with changes.
