driving boosted with no form of tuning..
 

hey guys I just finished putting a saab t3 turbo on my 1.6. i'll be honest its a lot of ebay parts but thats not the point here :p

It was a good learning experience with fabricating and learning about the car, looked on the forums for any questions i had.

and it is inter cooled.

What I'm wondering, is if its safe to run very low boost (5 psi tops) without any tuning/bipes/ anything? Using a innovate lc-1 for a/f ratio monitoring and a boost gauge, right now it seems to be pretty stoich and I'm kinda surprised, so this is why i ask. Ms2 is the next purchase but my wallet is hurting at the moment, so it may be a few weeks. If i drive gently and try to avoid too much boost will I be okay for a little bit?

Thanks

wtf is going on this week. Is it "Clubroadster pranks Miataturbo Week" or something?

Serious reply: Stoich in boost is about 2.5pts leaner than "safe". These cars were not designed for boost and they cannot compensate for it. If you think blowing up your motor within a week is acceptable, then keep doing what you're doing.

e: Just noticed you used eBay parts. Have fun with literally everything about your setup (manifold, engine, etc) breaking. Did you do any research at all here before wasting a bunch of money?

OP should have been aborted

ah yes knew the flame was gonna come :p

I read that Miatas are really great for boosting. Your car will sense the new parts you've installed and will make the needed adjustments on its own. Go for it!

haha thanks guys even though you're being dicks you answered my question

They just saved your broke ass a bunch of money and a shitload of trouble. I would say thanks would be in order.

I am grateful I have you guys :)

Hey hey hey, not all CR guys are complete idiots.

I'm only like 42% idiot even though I spend a lot of time on CR. 42% ISNT THAT BAD

No. 2 out of 3 aint bad. 42% is worse than that.

:laugh: props to both of yoiu

Cheapest route would be a FPR. But that's very 2007. We all need to run full sequential fueling and timing and electronic boost control in our Miatas now that we've reached 2013.

Although I had a FPR in my early days (two days actually) and killed my first motor in two days on the street.

Quality FPR + bipes or msd box = same price as a used MS or the DIY kits.

Why would you pay the same amount for older, less reliable tech?

If i have sex with my sister and she gets pregnant and has the baby, is this OK?

What are the chances the baby will be inbred?

Honestly at this point your best course of action is to light your car on fire. This will save you lots of time and money.

Really the only other option I see is lighting yourself on fire. Although this would save you the most time and money, it will be quite painful.

OP, ignore all these trolls. The stock ecu can compensate for small changes in boost easily just like any other car. 5-6psi is fine with no modifications at all.

Florida post :party:

It's well known that only a 1.8 ECU can compensate. He has a 1.6. So what he needs is an ECU swap to a 1.8.

I'm thinking the 1.6 will be fine up to 10-12 psi. OP should try it and let us know how it goes.

True, but if you mod your 1.6 ecu with a chip off ebay it works the same.

stock ecu is good for 10psi from a gt3076

Damnit I always forget about ebay. That damn website would have saved me so much money if I would have just bought everything off there.

Two ecus = double fuel

Is this what they mean by piggy back fuel management? Wiring two stock ECUs in series to double the fuel? :party:

This is amusing haha

Every time, bro

OP have you heard of E-cool you might want to check it out

Whatever it is do not run boost without a standalone, bipes, etc. You will fuck shit up. I should know..

Bitch your birth certificate must be an apology letter from the condom factory.

I have never turbo'd a miata, however I have plenty of other cars. I had a 1987 Turbo Coupe I ran 28 psi in with a 1:1 fuel pressure reg. and a stock ECU fooled by a couple potentiometers ..... oh yeah all force fed by a giant t-4 EBAY TURBO!? I'll admit I broke the turbo, but it was after much abuse on my part. Honestly, I had a harder time keeping that engine from "popping" head gaskets from the large amount of boost than tuning it. This is not for the faint of heart, as it requires constant fiddling, and will never run correctly.
The dicks are right, unless you don't mind blowing up an engine, or two, you should probably not drive it at all. I plan to buy a MS2 before ever even a single turbo part, tune her up with out the air meter and get some info piled for the turbo swap. The part where you put the turbo on is easy, just twisting bolts and running oil lines. Tuning is where you are really going to grind your teeth and pull your hair out.
Not that turbo'ing w/o tuning doesn't dance trhough my dreams at night. Check out this video, this guy clearly states he ran 5 psi with the stock ecu. He seems like he owns and tunes several turbo cars. He is a giant dork but watch the first few min of the video and you will see.

Yeah, with an FPR. That doesn't count.

Please, by all means destroy your miata... so that mine becomes worth more money in the future.

Matt and Torch, uiiiii!

lol, you guys are so harsh..

i can see you boosting 5 psi (ok, can you evenb boost 5 psi on that turbo? is the wastegate set to 5 psi, how are you accomplishing this)
now, if you finally figure out the 5 psi thing, the next thing is NEVER GO ON BOOST, EVER

that's the safest way of running a tubro without tuning.

no, you could try and estimate how much more fuel you need and inject in somehow...beats why the fuck you have a Wideband, but i'm glad you do...a small step in the right direction..
now, i'm guessing no tuning because you spent all your hard earned money mowing lawns around you neighborhood to buy that 200$ turbo kit that you put together with duct tape...but that was your first mistake...wherever the hell it was you read that turbo cars are cheap lied to you...

the safest way to run 5 psi, is DON'T

park your car, go read some more...and come back

and by the looks of it, have someone who knows about turbos to look at your setup, i wouldn't be surprised if you had the turbo installed backwards...

Haha I'm not a ruhtard, this is not my
First turbo'd car.. just the first turbo'd miata. it's not a $200 turbo kit I'm using a legit garrett turbo not some Chinese eBay turbo. The only things eBay were the cast iron manifold and down pipe. I realize these wont last forever, but the car honestly barely gets driven anyway, when they crack... I'll re-weld for now.

The whole reason I made the post is because I don't want to east money on fpr's and what not when I'm just going to get megasquirt soon. I've seen some guys around the Internet claiming to be running with no tunes or anything so I figured I'd ask.

i've sen running with no tunes as well, on 19psi on stock motors
all you need is a FLAPPER AFM (air flow meter) from a RX7, crack open the case, and change the values to make the mixture richer..

I would have no issues running 5psi with stock injectors, stock ECU, with the addition of an FMU of some sorts and a little ignition retard, I would be enjoying 140rwhp all day long while you assholes sit here and debate it.

I need quantity or quality at a minimum to enjoy something.

Your scenario offers neither.

Those were much simpler, much more enjoyable days...I can tell you that.

I remember when i enjoyed Bud Light.

Or had convinced myself that i enjoyed Bud Light.

I skipped drinking beer and went straight to margaritas.

Just when I thought this thread had peaked on gayness.....

I can't think of anything more queer than a frat party with a bunch of drunkards, drinking beer, who constantly want to remove their shirts and grope each other while pretending to be interested in the ugly sisters who show up, but confess their dark dirty secrets while crying alone on the bathroom floor covered in their own filth.

It sounds like you had a better time at college than I did.

I can't think of anything more queer than actually choosing bud light/coors/bud/michelob/miller/yucklick over all of the other shit that is out there. When your beer boasts about being served "ice cold", you know they're just trying to cover up the piss taste lol

fuck, no i want beer...and it is only WED...hmm, it must be friday somewhere in the galaxy...right?

You only drink on Fridays?

Amateur.

well, yea...kinda enjoy being sober while working :)

You're weird, work would be so much easier buzzed.

I'd kinda enjoy being at work if i was fucking schmammered.

I want a Malibu bay breeze right about now actually, since we are speaking of fruity drinks.

This was his drink of choice at the bar in the hotel at Sebring. Not gonna lie..... I tried it..... and I liked it. I did, however, stick with beer. Nothing exotic, just Samuel Adams Alpine Spring.

you should know better.

it knows no limits.
