Forgot one of the most important factor, intake camshaft timing. Earlier valve opening and closing traps in more air mass at slower piston speeds, and helps getting residual gases out of the cylinders with increased IVO/EVC overlap event (only works properly on boosted engines when EMAP is lower than intake pressure). Also the dynamic compression increases with early intake closing making possible to compress more dense air charge. All of this increases the engine VE making it to produce more torque.

I actually covered that in the 2nd part of this video series, just put a little more simply comparing one dyno sheet with vvt compared to another with no vvt

I had a twinscroll Borg Warmer 8374 EFR turbo which uses a gamma-ti turbine wheel using a ceramic ball bearing cartridge. The Full Race twinscroll system used a dual external waste gates Y’d into a 4 port boost solenoid. Dump tubes where dta. A port and polished head with upgraded titanium intake valves and black nitrided exhaust valves and 272 camshafts. That improved the volumetric efficiency of the motor which helped the transient response of this turbo. Being that the sti was awd made this car wicked fast from a dig.

The dyno sheet I show right at the beginning is a Borg Warner EFR 7163 on a STI. I think EFR are the superior turbos on the market for when it comes to faster spool. I was looking into the efr 7670 myself for a future setup.

I’ve looked into those as well but have never experimented with one

One tuner tip for getting rid of lag.. dont have your low rpm ignition timing advanced too much... the least advanced it is during your expected spool up rpm range the faster it spools up due to much more heat energy from the R-word ignition timing(sorry yt hates the R-word) then you can advance the timing back to normal after the turbo has spooled.. thats how i get full boost at 1600rpm mind you this is on a 347cid engine, but still the lack of turbo lag after doing that ignition timing trick was unreal.

yep you want advanced ignition timing for NA but the more timing you can pull out mid-high load the more response you see from the turbo and the faster you get into boost and making actual HP! I can see 4psi at 60mph 1800rpm from a 4.0L with a GTX3582r Gen2

you lower timing at spool not because of spool up. adv would actually give you more. you lower it to reduce knock because engines dont like being loaded at lower rpm. this saves your engine from detonation. any tuner worth a pay check for it knows this. the best and only way to really tune for spool is with a turbo speed sensor and a pressure sensor between the head and turbo. you want the psi at that sensor to match your target psi at the same time the turbo speed is in its efficient rating based on the compression map and your engine. without those 2 sensors you are just guessing.

How does the size of the wastegate relief port make a difference for the speed of turbo spooling ? . The wastegate will be closed until the turbos fully spoiled anyway ?

Yeah someone else’s video already covered that topic didn’t want to steal his thunder. But yes keeping heat and energy in the turbo help.

Although I agree with a smaller wastegate being good for higher boost in smaller turbos and keeping gate shut will help spool the turbo better.... running into issues w boost creep is the next issue or over boosting and running lean... where a secondary waistgate would be optimal... but I think the slight difference in size waistgate internal vs external really doesn't matter if ur closing it off completely to spool... id rather have the ability to bleed it if Slightly better for above reasons... smaller waistgate size is good for higher psi and larger is better for lower psi... its all about bleeding off power from turbo... after all a closed loop would just build engine speed and back to turbo around and around until blows up eventually... so bleed air slowly for higher psi... bleed air quickly for lower psi once you go BIG turbo the entire issue flips on its head Also side note on exhaust manifolds... boost threshold wont change from the length because the flow is already constant inside the header flow is always a better target when choosing manifold... although distance to turbo can make a difference if very far cause loss of heat... so header tape/ceramic or cericoat helps there

Your ic piping

also its good for your viewers to understand that fast response isnt for everyone. with faster spool times, means more stress at lower rpm, more stress on the crank, and more induced heatsoak and camber heat earlier on. which are the main killers of turbo engines besides the obvious main killer of all engines, cold dry oiling start. it requires changing oil more to monitor engine health and heavily thought out induction as well as cooling to keep egts and iats in check.

Question. You mentioned that the waste gate being internal and smaller was a factor in spool up being quicker. But then you mentioned that the 4 port would keep that closed during spool up. If the 4 port is keeping the waste ate closed, doesn't that negate the smaller size being better? Having the smaller size would be a drawback to control, right? I am assuming that even if I had a 60mm external wastegate. If it is closed during spool up it is the same as having no wastegate.

@Bang4BuckRacing

7 ай бұрын

I definitely see your point but in reality how many people are actually get and use a 4 port boost controller? Even a lot of tuners are just scared of what they don’t know and won’t learn how to tune on one to get these types of results . So majority of people will still just use a 3 port, and with out that 4th port holding the gate shut the exhaust gases on its own will push open the gate. And it seems from what i have looked into with a 3 port alot of tuners just always the gate being supplied with air through the entire band. Even on mine with the 4 port was never fully closed down low but was shut like 75 percent. If you did that exact same thing with a 60 mm it would still lose velocity due to volume size. But yes in the theory that it’s fully slammed shut I’d say you’d be right. I believe a lot of people setup up EWG setups wrong and lose to much velocity when they don’t have to and if I was a decent size KZreadr I would build another project to test my theory on but I’m not there yet lol

I wasn't aware that the 3 port wasn't able to hold the wastegate closed well enough. But it would make sense that they developed the 4 port to deal with that. There are electronic external wastegates now as well. Way more expensive, but eliminates the need for vacuum and boost lines to actuate the valve. Pretty cool stuff. I appreciate you getting back to my question though. A lot of good information in the video and in these comments.

My Mazda leaves the waste gate open until it’s under load then closes. I’m trying to find a way to have it close early enough that’ll begin to push air into the engine around 2,500-3k rpm.

The IC piping plays a little bit more of a factor than the intercooler it’s self. “you want to run the smallest possible without going over a certain air speed. 304 MPH or 0.4 mach is the point at which airflow meets increased resistance (drag) and flow losses are experienced.

In a straight line sure some corners on tracks and for autox especially you get lower in the Rpms. But you knew that 😀

Volume of the turbo plumbing has neglible effect on turbo lag, the turbo has such a high CFM it litterally does not matter, do the math on the time to fill its basically nothing. Its the surface area of the exhaust that effects turbo lag not its volume, this is because the exhaust tempreture is reduced by higher surface area pipes, lower temp exhaust means lower exahaust energy and thus less energy scavenged by the turbine and more lag and a higher threshold, insulating those exhaust pipes remedies this. Watch the driving 4 answers videos on remote turbos. Otherwise good video.
