At 18psi with out retuning or anything I pulled my roomates STI (Turbo XS TurboBack, UTEC w/ Stage 2 map) by 2 cars from 65-125mph. With my 14b he used to walk me by like 3 cars or so from 65-120, and that was before Utec.

Nice!

[floored4door]

Weak, J/K!

[2fastNturn]

full boost (19 psi) at 4.3k rpm. Its fun but I thought it would be alot faster.

On the 14b I would pull about 2000hz on the afc.... now I see 2600hz

[David]

what turbo is that?

[TheJackal]

I saw your post on CRN, how much does that turbo flow? Looks pretty big, is that comp housing AR .60? Seems like your lag isnt all that bad..

[2fastNturn]

PTE SCM5031E

Its a Precision Turbo 50 trim with a "stage 3 wheel" .76 trim exhaust side, with a Mitsu exhaust Housing. Its got a 31mm internal wastegate.

Supposed to be 49lbs/min.

Well in garrett talk, that stage 3 would mean the turbine wheel and how much it flows... I think I have a stage 2 or something, I just know it takes forever to spool

[doctorstupid]

That thing is bad ass :D

Wait until you get her tuned and are able to spin that badboy up to 25 psi on pump gas daily on your stock bottom end. Gotta love DSM's. Got fuel?!

BTW, PTE turbos seem to be known for smoking. If you see smoke, you'll know where to look.

Well... no smoking yet, but a bolt snapped of in the exhaust housing. I didnt even touch them, didnt reclock it or anything. I'm thinking the bolt was torqued to tight by PTE or ExtremePSI. So I'm going to try a lefthand drill bit and if that doesnt work I'll send it back.

I would ask them before, because that might void the warranty

I have a similar setup “eta32 50 trim” internally gated… now externally gated. I purchased it used from a guy who threw a piston rod on a stock bottom end @ 22psi. He only had the turbo installed for a few days… Once you decrease the intake and exhaust restrictions you will notice over boosting in 1st and 2nd gears hence the need of an external gate. My bottom end is built so it can handle the boost. I blew the stock piston rings with a TEC-18G turbo @ 18psi.

[2fastNturn]

Stock dsm bottom end can handle 400-450 whp. IF it is tuned right.
18g turbo at 18 psi really aint shit, and the only reason your engine would have blown is from knock.
We have run my brother EVOIII 16g @ 25psi all day long, stock block with arps and mls head gasket.

I doublt I'll see boost spikes running 20psi daily or boost creep. The only reason I havent turned it up yet is because I still have a stock bov.

I agree with this, but at these power levels on a stock bottom end you must be very very careful and know exactly what your doing.

Well.... I hope to make close to 400 whp on this turbo, but with out cams I think I'll be around 380whp uncorrected. Guess I'll find out if my tuning is good :) So far at 19psi I get 0 knock except 1-3 counts if I just floor it in 5th gear.

I havent logged yet with this turbo because my brother has the logger, but I did bump my timing already. So far I'm kind of disappointed with this turbo.

[deadly dsm]

Stock DSM bottom end is good for 400-450 hp, at the wheels, on a slow day.

Don't just floor it in 5th gear, that's for inefficient V8 pushrod bricks. Downshift that bitch and hit it.

You also have to remember that just bolting on a turbo is only a small piece of the puzzle. When dealing with the stock ECU and piggyback controllers, you gotta have everything dialed in right to get the best timing and only slight knock sums, say a 5-7 count. Without bigger injectors and a modded MAS to help cancel out the huge airflow signal you now have, you probably aren't getting any timing up top. If you go too far the car will feel dead as well.

A 50-trim/stg3 combo internally gated turbo netted me a 12.0x at 115-117 traps and a 12.8@109 on pump gas up there at full weight. I pushed 25 psi daily on pump gas, stock bottom end. Don't be skeered, but do pay attention to your logger!

I'd also recommend an in-cab electric fuel pressure gauge. Because, no matter what else is happening, if that FP gauge starts falling at high rpm under boost, get out of it.

I have everything I need but a BOV. Also piggy backs are for pussies, I modify the eprom my self. http://www.highaltitudeimports.com/images/smilies/cool.gif

Curious what timing you were running on the 25psi/pump tune?

[mopsi]

I did this with the 18G to a stock piston. My guess is too lean fuel to air ratio and high knock. I didn't have a data logger at the time.

[TheJackal]

I ran 24 pounds on the stock internals until my BS seized... They look like they got pretty hot.

[2fastNturn]

I broke a piston too... 18 psi on a S16g... shit was knocking like a mofo on 30deg advanced base timing. Dumb shit that ownend the car before me had the cas cranked, and I was stupid and never checked it.

[deadly dsm]

Curious what timing you were running on the 25psi/pump tune?

Base was usually set at 7-8*. Logs usually showed 17-20*, so figure 19-23*.

On VP race fuel, it always seemed to be best (as limited by piggy back) when I got the timing around 17-20* with some knock count happening.

[2fastNturn]

I logged 37 lbs/min this weekend at 19psi... so I am already getting to the point were the cams and intake manifold are a restriction. When I turn the boost up I should see some huge gains in air flow, hopefully.'burnout:

Do you calculate this or is it just given, I have a pocket logger that I havent messed iwth that much, is there a converstion for Hertz?

There is a conversion, but its more then I want to deal with... and I havent seen all the numbers posted.

It wasy for me to calculate because I'm runing extended fuel/timing maps and I dont change the ariflow signal at all.
So all I do is
((Grams/Rev) x RPM) x (1lb/ 453.59237grams) = Lbs/Min

Since I'm using extended maps and dont molest the air signal, I know how much air I'm taking in (gram/rev). Which I figuer out by looking at my timing values to see what load row I'm on.

There is also a newer MMC that will tell you what load row you are on and they are working on lbs/min as well..... but none of that will help if your air signal is being altered by a piggyback.

[TheJackal]

Oh ok I got it, so I should probobly find the Hertz translation, I guess I could still log my stocker and check it out, but thanks none the less..

[DSMxSteve]

Theres more to than that believe but I am not totally sure. Don't you have to factor in air temp and Barometric pressure as well to get a good (lbs per min.) air measurement?

[2fastNturn]

If you want to use hertz... yes, you need to factor in those.

But if you go by grams/rev which is what the ecu uses to determine the load row then you dont, because the ecu has already made the adjustments.

[DSMxSteve]

Ahh, I see, Which software is this?

[TheJackal]

Ahh, I see, Which software is this?

I assume you can use a pocketlogger, AFC (for herts), MMC, or DSMLink

[2fastNturn]

Ahh, I see, Which software is this?

Any logger will do if you know your timing values and have the octane reset code (or unplug your ecu to reset it). Basically each load row is each to a grams/rev value, and there are 12 load rows.

For example... I log a pull and I see my timing values are 18deg@4k, 18@4.5k, 19@5k, 20@5.5k. I can look at the stock timing map and see I'm at the top load row, which is 2.06 grams/rev.

or the newer release of mmc will just tell you what load row you are on., as a matter of fact the newest release shows grams/rev http://www.ecimulti.org/mmcd/

[DSMxSteve]

So actually knowing the timing map is the ultimate idea. OK you're well beyond me.

[2fastNturn]

Got the new BOV on.... turned up the boost to 23-25psi, damn weather messes with the settings. Logged 42 lbs/min at 24 psi. That should be good for a little more the 300 whp uncorrected.

Looks great!!! A couple runs on the Dynojet at MAC Auto and I garantee 300+WHP!
