Hey Chris did you ever figure out the ventury fuel system ? did making the return hole bigger works ? im going 1jz vvti swap i might bump in to the same issue. >.<
It all depends on the wideband you using the best way to go is aem wideband thst is calibrated already some afr you have to tune to calibrate the engine.
I think those regulators are like oxy/fuel welding/torch regulators. You start with the screw almost all of the way out and then pressurize the system. Then you screw it in, raising the pressure with each turn. If you charge the system with the screw almost all the way out, you get a full range of adjustability.
Fuck ads.
Change the injectors Chris
Afr is fine 14.7 to 1 is ideal
You can clock your turbo 30-35 degree max for the oil return line does not touch the exhaust manifold.
Those tiny holes are 'Venturi pumps'. You may have just stopped/reduced the effectiveness of the whole assembly…
Disliked for the stupid fact that you're plugging a company that most people don't give a shit about…
wrap your manifold in heat tape and you should be fine for the oil lines
Don't put thread tape on AN fittings. A/F ratios are fine for crusing light throttle, try a full throttle pull.
what tires are you running man, and sizes?
Lol cleetus mcfarland had a similar problem and it was the computer
Many pounds in manifold = danger to manifold
It looked good to me, you won't know for sure until you can go wide open throttle. When you do get it together enough to go wide open throttle, go slow and make sure you aren't consistently over about 18ish. Peaks and valleys are very normal. If it continues to rise as more throttle is applied consistently you are running out of injectors. But for this episode it looked good to me.
The turbo doesn't have to be completely straight, you can clock the CHRA, you can talk with Garrett to verify the maximum amount, that should give you some room to get your oil drain line away from header, also most all vehicles I have worked with, even other Toyotas say 43.5psi fuel pressure with the vacuum line off, also you were not much into boost, so the fuel pressure regulator won't increase to much
Your manifold can get up to 900 degree celcius, id defonately run it as far from the manifold as possible, let alone running it through it 😛
Set base pressure to 43psi, factory requirements went out the window when you tossed a giant turbo on it. Psi is a relative term, just because you're at the same boost level doesn't mean you're moving the same amount of air. You're light throttle is perfectly acceptable, you only should start to see it richen up when you're in boost. Any turbo car I tune, I set base pressure from 40-55psi depending on the setup. Good luck and keep it up!
you aren't hitting boost because your single turbo is more laggy than the stock twins. Once you actually hit boost(more rpms & load) your afrs will richen out
It's running lean due to the tuners trying to correct the previous issue. Have it re-tuned.
14.7 is normal for light throttle and cruising. On an N/A vehicle Heavy and WOT throttle would be around 12.5-13.0 depending on the platform.
On a boosted platform it should be near 12.0 during the transition into boost and usually 11.5 at WOT. Again every application will be different and vary a few 1/10ths but nothing crazy. Also staring at a wideband will make your head spin during transient throttle swings. Its ok to see a little rich or a little lean, by a little I mean .5 difference as long as it settles out quickly it's fine but it can be refined with a tune (and it should be).
You'll have to fly Trevor to come rescue that brz
14.7 is fine up to -0 HG of vaccum. Once you start seeing 5/10 psi of boost thats when your AFRs are going to want to be in the 13.0/12.5 range and then 15/20psi of boost WOT you want like 11.0/11.5 AFR
such a big win for the channel! finally!
When are you going. To make this car manual
Chris, instead of going through the nightmare of converting it to hard lines, why won't you just heatwrap the manifold and the turbo ?
All this effort and yet Sloppy is hitting 1000+hp on a 10th of your budget….
Sick episode mate
Manual box tunable ecu and tune it after everything's Ben tidied up . Or your just going to keep breaking stuff.
show the pc build 🙂 and play battlegrounds with subs 😀
Part throttle should be 14-15 and full throttle should be low 12's… that's what it has been tuned at on my charged s2000…
Damn brother, your whole cooling system needs help lmao.
You aren't making any boost. Use the front feed port for oil supply. Clock your turbo a little bit more, there's a range you can get away with for the degree it's clocked. It's running super lean because it was tuned super rich, it needs to be retuned. Talk to your tuner for fuel pressure tuning as it will need to be set prior to adjustments. Don't run rubber pipers near your manifold.
