how to get a turbo to spool faster

[Kyromoto]

Ive been looking on the search and cant find anything on there. so im just wondering. besides getting bigger more free flow exhaust or a cold air intake. what else can you do to get your turbo to spool faster. Im fine with the PSI i get just want less lag . o btw I have an evo 3 big 16g turbo on my 92 talon with greddy BOV, apexi exhaust system 3 inch. cut the air box and Maf mod. thank you for any info...

I had spool issues. My wastegate flapper was hung open. I was not hitting full boost till 4000rpm an i didnt know what to think. If its not that boost leak test an get back to us. You have to know if you have an leaks before we can go on from here. What exhaust do you have.

+1 for the cyclone i love it. I wont run my car without one now, it spools so fast. I outspool my friends 2g with 8.5.1 and a 14b. I have 7.8.1 an a 16g. That cyclone is my fav mod yet i cant wait to see how it does on a larger turbo.

The ebay manifold can be considered a definite cause, its longer runners will make the turbo spool slower.

and to the guy about the injectors im not running stock injectors and so if you really dont care then stop replying to this thread as well as all the other people who keep replying when they got no need to.

I thought you had nothing to tune with? If that is the case then that is a major part of your spooling issues. What injectors are you running?

I used to find that my 16g didn't spool all that quickly and it was annoying on a mostly stock car but as I continued modifications I've come to the point where my turbo spools nearly as quickly as when I had a t25 and quite frankly sometimes the power comes on more quickly than I'd like going stop sign to stop sign in my neighborhood. You can check out my mod list to see what I've done, and when you do consider that my car is built as a budget (but reliable) car so nothing on my list is prohibitively expensive and all of the parts were fairly well researched to work well together without anything being significantly more shiny or high end than necessary.

One of the things that really helped my spool time was tuning and after a fair amount of experience I would not claim that the number one most important and useful mod that you can do to your car is a solid and full featured tuning system. It may not sound as sexy as saying that you've slapped a bigger turbo on but if I were doing this all over again I would start with the tuning before I ever touched the turbo because at a similar or lower price it actually does far more.

Also for what it is worth I nearly skipped replying to your thread because of some of the comments in here toward other members. If you have a problem with a post in your thread you have a few options including, ignoring the offending post, placing the user on an ignore list, reporting the post/contacting a mod, or more politely asking the user to refrain from future less than helpful posting. If you would like the best advice and help then I suggest toning yourself down as civility, politeness, and proper grammar/punctuation/spelling are all highly valued on this board. I am certain that I am not the only experienced member of the board that feels this way.

Yep, without a tuning device your dead in the water. You have to take into account that the turbo is simply "assisting" the motor to make torque. How fast a turbo boost gauge spins means jack. Cover it with some tape, and when your engine is tuned properly it won't matter. I can get my car to make outstanding torque while I'm still spinning in vacuum and at very low boost. In this respect, I hardly care if the turbo is spooling up fast or not, to a point of course.

For an ebay 16g, 3500 rpms is about the norm. I see about 3200-3300 on a genuine EVO3 16g and that is about as good as it gets. Speed density and removing the MAF will knock that number down about 100-200 rpms at most from my experience. Thats assuming you have a free flowing intake, exhaust, no cat, and all that jazz.

get an o2 dump

What does that have to do with anything?

Probably it looks cooler and you'd mentally think it's faster spooling just like putting a big spoiler and/or painting flames on your cars.

 

[JusMX141]

Ah yes, the "bling-speed spool factor". How could I forget?

You can get adjustable cam gears and mess with the timing of the cams.

Thanks a million for posting this, this help me fix a laggy 14b problem i was having. Sorry for the OT.

get a super light weight flywheel

 

[RallyEclipse98]

Resolved with the cam gears?

Listen buddy, we are on this forum to help you. If you're going to refrain from posting information about your car/ updating your mod list - honestly how do you expect us to be any help.

If you want to reply with insults and flames good luck getting any help on this forum. You obviously have a lot to learn about these cars and this forum so quit trying to run before you learn how to walk.

If you're running anything other than stock injectors without a tuning device, then you're not "running fine." Period. The people who are commenting about that obviously know what they're talking about, so then they DO have a need to.

Quoted for truth. Future disrespect to people who are trying to help you will simply result in your thread getting shut down. Please remember to use proper spelling, punctuation, and grammar in your posts as well. It really does help us understand where one sentence starts and another ends. Thank you in advance.

You haven't done a boost leak test, you haven't done a compression test, you have no tuning device for your larger injectors, and you're still complaining about turbo lag? Get those taken care of and I'm sure you'll find positive results.

yeah im definitly convinced about the cyclone and im going to get one ASAP. and im running a full apexi turbo back 3 inch exhaust kit. also havnt had chance for boost leak test today (couldnt get all the parts yet to build a tester) but i cleaned out my IC real good (completly coated with super dark oil (had to of never been cleaned before) but after driving it seemed actually alot better. still not what it should be. but Im sure when i find and or fix boost leaks itll be even better. I woulda got more involved for the boost leak but today found out my tie rod end was almost about to snap off so i spent today getting a new one. replacing it. and also the IC plus all the IC piping plus just doing a general check of hoses and stuff. i think tomorrow ill do the boost leak test and then get back to ya. after the leaks are fixed plus the cyclone are put on geeze this car will be a beast

Thank you Mork.

im only saying shit to people who are acting like idiots. the people who actually contribute ideas get nothing but thanks from me. but idiots who say strap a rocket to ## car shudnt even bother wasting my time. and I admit there is alot to learn about these cars. but im sure as far as my car is concerned i know more then most. seeing as i have completly built 2 of them. every nut and bolt has been replaced at one time or another and one car was done all at once for a complete rebuild. so i dont want my time wasted by people who just wanna be smart asses. and whats this shit about not updating my parts list? to my knowledge it is updated. i have my talon up there atm cus thats the car im currently driving.

MR MODERATOR. if people are going to disrespect me for asking a freaking question then thats what they will get back. how bout tell them not to post in a thread if all they wanna do is crack jokes huh??? and you can even look. to EVERY single person who ACTUALLY tried to help me i have told them thanks and that i appreciate it. so i do respect people when they arent being idiots to me

thats my 2 cents.

 

[the_mork]

I can see it as understandable that you would fill your mods list out for the car that you DD however the mods list is incredibly important for making suggestions that are pertinent to the car that you are asking about. At this point most of us who are trying to help you still aren't completely sure about a few things when it comes to your car so I strongly suggest filling out your mods list to include both cars. Simply denote each as a separate heading in each field. Also please answer these specific questions so that we can best help you.

1. What injectors are currently in the car?

2. Do you have a tuning device? If so what is it.

3. Do you have a wideband o2 sensor?


While there is nothing wrong with getting a cyclone manifold it may not be your best option at this point. If you want your car to be faster there are likely a number of other upgrades that you can do for the same price or less that will have a bigger impact. This is based off of a few assumptions about your car at this point because I don't know all of its current modifications but if you post your mod list we will certainly be able to steer you toward the most efficient upgrade path. I know I ended up being really excited about the evo3 intake manifold at one point and while it is certainly a great piece I would have been better off at the time buying other things for my car such as a tuning device or exhaust. Now that my car has progressed it fits my setup perfectly but I could have been going faster earlier for less money.

As for replying to idiots that abuse your thread I would suggest that witty and tactful remarks are generally given some slight leeway and that leeway gets somewhat larger as you become a long-term established member of this community but the proper way to deal with annoying people is to report it to a mod or ignore it. If you report it and the post is actually offensive or just downright stupid it is likely that it will be deleted and your thread cleaned up. Trust me that being polite and turning the other cheek will get noticed and people here will respect you more. The issue also becomes less pervasive as you move to the more tech oriented sections of the site and your post count goes higher, for some reason noobs are a little bit more afraid to attack people who have been around for a while.

Any monkey can change parts, it becomes especially easier when you only work on one model. That being said most people here have pulled their motor once. I personally am on my third.(1st: high miles, blown rings, 2nd: POS kar king longblock, 3rd and current: strongest, built by myself)
Diagnosing a car and knowing how things operate is what makes you a knowledgeable technician.
No one is calling you stupid - if you feel you must boast, go ahead.

If my comment offended you about your injectors I wish you please elaborate how my comment was uninformative due to the fact you haven't stated a correct means of compensating for larger then stock injectors. Mork elaborated about your "parts list" in his last post.

Unfortunately we cannot lock out the people from posting stupid comments or incorrect information. If you think this website is bad, check out rx8club.com....they suuuuuuuck. Digging through posts to find informative information takes days there, compared to minutes on this forum.

 

[Achelea]

I'm kinda confused about the fly wheel comment. . . But that's off topic.
I have a few questions. We've established he has a GReddy BOV, 3" Exhaust, Evo3 16G turbo and slightly hacked air can.

As his car sits right now as of last time I talked with him. His Oil pressure gauge works intermittently, and it started to run hot on the freeway. ((Not trying to bust your balls Jeff, I'm trying to help you keep your car together.))

Even Road Race suggest

If your turbo is dead, time to upgrade. With the 16-G, you can keep the boost down and need only an upgraded fuel pump. To run over 15-16 psi boost on pump gas safely, you will need more fuel.

RRE 1st Generation Eclipse  Upgrade Path Look at the section under TURBO
You're running LEAN. At the very least take the fuel pump from the rally car and rewire it in the Talon. ((I think the stock pump and injectors are iffy at best. Car runs, but hardly fine.))

How about just running a small shot of nitrous?

 

[Achelea]

Nitrous cools the air. If he is running Lean as it is right now, putting nitrous would make it run more so. Besides, Nitrous tanks are one shot toys that are expensive to refill.

 

[MrBoxx]

How about just running a small shot of nitrous?

Here at DSMTuners, we like to help fix whatever problems there are before adding new ones. The addition of an oxidizer to an already-taxed fuel system with (as of now we can speculate) NO fuel tuning device would only compound matters.

Most people have no problem with the spool of a 16g on an otherwise well-running car. Boost leaks, exhaust leaks, faulty fuel components or mismatched fuel compononets (larger than stock injectors with no tuning device counts there), etc, can all cause spool problems.

Adding nitrous, a lightweight flywheel, or an O2 dump is NOT going to help these matters.

 

[clean96GST]

So whats the difference from the JDM cyclone compared to the ones that come off 1g's?

 

[ccwhisenhunt89]

ya what is the difference everyones always told me cyclones arent really that much better .......

 

[fergulus]

A quick search of this massive website will show you that a 1g intake manifold has nice large and long plenums, whereas the cyclone intake manifold is basically cut in half (4 long plenums and 4 short plenums), where at the low RPM you have longer plenums for the air to travel (helps with low end torque), and at higher RPM an actuator opens the shorter plenums to increase overall flow. The search feature is preached about on this website for good reason, because there is a wealth of knowledge here.
