what......my 14b pulled harder than my e316g

[97-gst]

I finally got my true mhi evo III 16g on and i wasnt too impressed. At 18 psi it pulls decent and my logs show more airlow but i swear my 14b felt like it pulled harder at 18 psi. At what boost level does the e316g come to life?

 

[fullCircle]

May not pull harder, but may be faster. I would say your torque curve smoothed out but improved.

14b may have a shorter but more aggressive torque curve.

 

[lilbro717]

did you retune your fuel it for the increase of air

 

[dsm03]

Would it seem that it pulls harder because it spools faster? Although, the E16g spools decently quick!

I left it the same tune as i had my 14b on, a/f at WOT was 10.9-10.1

It really seemed like the 14b pulled a little harder. I really cant believe i spent that much money for a downgrade WTF

 

[akira235]

it wasn't a downgrade. take it to the track and you'll see. do some tuning and crank the boost up another 6lbs and you'll REALLY see.

 

[97-gst]

im on stock internals, is that really gonna be safe?

 

[LiquidX]

The only thng you would need to upgrade so you can hold more boost is your headstuds for piece of mind. Composite HG is good for 28psi or so. The internals are more for being able to take more torque and horse power.

Just log as you increase the boost and see how the motor likes it.

20+ psi. Also make sure you check your timing table. You'll need to retune your car before you can really "feel" the power difference of the mighty Evo 3.

That turbo is happy at 20psi peak boost, i would tune it for that, thats the boost im running. Hella fun.

 

[pboglio]

Hmm, I was not impressed with 15 psi on the EVOIII 16g, 18 psi feels decent, 21 psi feels good, 23 psi feels great. You crank it to 28 psi and its like shooting heroin every time. This is more a function of the motors ability to make power at "x" amount of boost than it is the turbo's fault. The main advantage I saw with the EVOIII 16g was regardless of the boost levels being run, it seemed unaffected by high ambient temps. You could run 20 psi in 100*F weather and it would still plant you hard into the seat. It was the consistency I liked about the EVOIII 16g.

FWIW, I made the power numbers below my avatar on a dynojet at 22 psi on a e3 16g. Granted it was on a stroker motor, with FP3 cams and all the bells and whistles.

 

[mikejsmith1985]

I say put it on a dyno or take it to the track before you make any decisions. The @$$ Dyno isn't as accurate as you may think. My Brothers vette doesn't feel like it pulls as hard as a buddy's lightly modded Trans Am but the Vette is definately faster it's got a much smoother torque curve than the TA so it doesn't pin you as hard but the TA is only a low 13 sec while the Vette runs 12.3 - 12.5

Seems like your a little rich, with going really rich it will bog it down. Retune with the e316g at your desired boost and get that WOT tuned in.

Indeed, below 12:1 runs exhaust gasses that are too hot for turbines. If you want longevity of your turbocharger, increase it closer to 12:1. Once your A/F is set, slowly increase your timing until you start seeing knock (.1 degrees or so).

You MIGHT get 17 degrees out of it at that A/F ratio.

So basically i need to tune for like 20 psi today, but how much boost will the stock internals hold from the 16g if i just crank it up alittle more without headstuds? This is my DD btw. I guess i need to take cut my injectors back alittle to lean it out, ill post up a log later with my results

I would not go much higher than 20psi w/o headstuds.

What are you using for tuning? N/m checked your mods. V3 lite.

Alright, well you need to first off make CERTAIN you have no boost leaks between your air metering device and your engine. If you're running a GM maf, calibrate it. After that, dial in your STFT's and LTFT's.

Just follow the wiki guide.

Yeah so last night, i was loggin a 3rd gear pull and about 4k it felt worse than my t25 did. i was like WTF. I did however catch the boost gauge needle drop from 18 to 13 so guess im gonna do a ble and a compression test

Can somebody please tell me what it means when my log shows that last night my airflow picked up over 15 extra gm/s which is now like 285+ gm/s?

It sounds like you have boost leaks.

Can you give me that airflow number in lbs/min or g/rev?

 

[97-gst]

37 lbs

 

[Boosted98gsx]

37 lbs

On a 2.0L running 18psi, that's definitely not right. Check for boost leaks, and calibrate your MAF.

 

[97-gst]

no boost leak, maf translator is dialed in, i advanced my timing a little as i had retarded it a tad to avoid 1 degree of knock. It seemed to pull equal to mny 14b but not really harder. i guess ill get me some headstuds and crank it to 25

 

[BrokenTsi]

You dont need headstuds for that. Just a good tune. Ive done 30psi on stock engine with stock headbolts on a 60-1.

Did you check with a boost leak tester? Can you post a log for us?

 

[97-gst]

boost leak tester showed a little but nothing bad

 

[fran_drivertsi]

Friend of mine runs 32psi peak and 25 hold on e85. At 30psi, torque is like HOLY SHIT!!!
