E316g E85 Dyno Results+405whp+28psi

[boosted86]

headed out to the dyno today to see what my setup had to offer on e85. overall im pretty pleased. put down 405.98 to the wheels. she knocked a little bit but not to bad.( max of 1.8 counts)

 

[Yngvar]

Way to going 400 hp on a 16g

 

[JusMX141]

Wait, I thought every car with a 16G made 400hp. [/sarcasm]


Seriously though, quite impressive. I love corn juice.

 

[dSmgs-T]

those are ridiculous numbers!

 

[Boosted_out]

Wow thats awesome. Really good numbers!

 

[TSG59_Steve]

Very nice numbers.

 

[turbotalon1g]

Nice! Welcome to the club its awesome, esp. against 600 bikes.

 

[jrohner]

Nice results. Your profile says 28psi, are you getting it to hold that much at peak hp? Mine drops to 22-23 at my peak hp of 5600rpms no matter how much high I have the boost at 3000 rpms.

 

[matthewdesigns]

Nice numbers! Is your profile up to date? I see that there is no cam upgrade, and only a swap to a 1g intake, so I'm curious.

According to the log, unless I'm reading it incorrectly, you stop showing increasing airflow and timing at about 6260rpm (27.68sec on the log), and then it looks like you let off. Is part of the log missing? Are you seeing a decline in airflow above that point? If not, why didn't you run it up a bit higher? I don't usually see max airflow on my E316g/e85 setup until about 6900rpm, and my timing maxes out at 20*. Again, just curious.

Post a log and what PSI?

yea i peaked at 28psi and fell to about 24 by 6.5k

yes you where reading the log correctly. since i dont have cams my power drops down past 6.5k so i usually never bring it past there. im also able to hold a max of 40 lbs/min at this rpm point. then it will drop don to like 37lbs/min...

i did post a log( its the .dat attachment) and this was at a peak of 28psi falling to 24ish





my next upgrade will deffentily be some 272's so i can extend my power band. although ,right now my biggest dilema is traction...im spinning tires in 4th and my tires still have 1/2 thread on the... i hate fwd!!!

I usually see two peaks in airflow, one at about 6900rpm, another at about 7150, both of equal amounts (36lb/min), and I'm wondering what is netting you 4lbs/min more airflow than I see on my car. Are the 1g intake manifold, FMIC, and 1/4" larger intake piping enough of a difference between our setups to make that big an increase in flow? And I know elevation plays a part in it, but I'm having a hard time seeing that much difference, all things considered. I'm not disputing your log, just wondering out loud about how much less I'm flowing.

there are alot of peramters that the ecu will look at to determine airflow. the biggest one is your IAt's. before my CAI i was metering airflow right around 36lbs/min at 26 psi. when i stuck my funnel in my bumper and lowered my IAT's i gained about 2lbs/min bringing me to 38lbs/min at 26psi. also if your tunning with dsmlink, your maf MUST be calibrated correctly after your switch over point( max boost at a given rpm) to have accurate airflow readings. and elevation is also a big factor( air density)

ill attach a log that i did right after my CAI.

 

[matthewdesigns]

Thanks for the insight. Gaining 2lb/min from just the CAI is pretty impressive...I would not have guessed it would have made that large a difference. I do have my filter blocked from the rest of the engine bay, but as I'm on a big smic there's no snorkel in my future, which would help a lot more. I've got a Keydiver chip, not Link, so I would guess a little could be made up there, too.

Oh well, more food for thought!

 

[JusMX141]

Makes sense.....I believe the window for perfect air intake temps before getting timing correction with a 2G MAS is 64*f-84*f. If you were at 110*f before the CAI and now you're at 80*f, no timing is being taken.

 

[JayRolla]

Very nice. I will be taking mine down in a few weeks and hoping to break 400 corrected whp. What timing are you seeing at max torqe?

 

[JayRolla]

Well I just noticed and looked at the log and your hitting about 10-12* when boost hits. I would raise that to about 14-16* down low. Then you hit about 18* at top which is good since you are seeing knock. I see maybe 4 counts at most and thats at the same boost level at 24*. I wonder why you are knocking so easily.

Your afr looks a little lean, what is it at? I cant read the damn graph that well.

Great numbers. Congrats!

Matthew, as a comparison with someone at altitude, I'm supposedly seeing 42 lb/min with my big16g. I can't calibrate my setup like the link guys can since I use my own chips, but if anything, our calculations for lb/min should be similar since were both using stock type chips with the same maf calibration curve. Since I'm a 1g, though, I have to convert the g/rev to lb/min in a spreadsheet. I don't have numbers at a track recently to back this up, though, so who knows if it's right.

 

[JayRolla]

42lb/min is a lot for a 16g. Most ive ever seen is 38lb and ive only seen other hit 40lb/min. Thats pushing some good air. I want to go to the track next year and hoping for a low 12.

 

[yokotabrat]

Yeah, that's why I'm hesitant to say it's really true, but that's what the ecu is telling me in g/rev in second gear. Maybe it's even higher in 3rd, not sure. My setup is pretty geared toward a 16g, though, so maybe. Adding speed density in the next week or two should help more.

Good luck with the low 12. I'm sure you can get there. I'll hopefully be right on your heels sometime if I can ever get a 4 spider center diff.

yes, the reason why i kept timing at that level where you see 10-12* is because boost is still climbing and dont want peak cylinder pressure before peak boost. usually,my IAt's are under 80* under wot pulls ( incoming airflow hits my cai) but since i was on the dyno i had no incoming airflow so my Iat's went over 80* degrees( pulled a degree of timimg) i will usually max out about 20* by 5k.( on the street)

the max knock count on the dyno log was 1.8* i usually never adjust a tune for anything under 2*.

my AFR's are about right for E85. you should shoot for 10.5:1 to 11:1 on pump (wot)
and anywhere from 11.5:1 to 12.5:1 (some goes as far as 13's) on E85( slower burning fuel)

its really hard to knock on E85. anyone who has pushed a 16g to its limits knows that it basically turns into a hair dryer past 25psi. knowing that i was able to bring it to 28(peak) and minimal knock ( 1.8 ) shows alot about the knock suppressing capabilities of E85.

 

[JayRolla]

The fuel does burn slower so thats why we can get away with higher timing. I would not tune leaner than 11.5 on even e85. I shoot for 11.1-11.3 on my e85 tune. Jack here in the springs has seen some burned up valves on lean e85 tunes and would never tune a car leaner than 11.1 even on e85 at his shop.

That is most likely are large turbo cars but I like to play it safe. The difference from 11.1 to 11.8 showed really no difference in my car. But going from 20-22* max to about 24-25* max showed a lot more gain on the "butt dyno".

 

[DSMunknown]

C'mon next season...

 

[Black_Bullet]

Good numbers OP, hopefully Ill be right behind you before this years over!

 

[PIMking]

holy cow I just looked at your log and DSMlink said that you made 411 hp at 5300ish I did not realize that its that close.
