just a little update 20-21psi no meth just working the tune. (stock clutch)
410whp and 395tq

 

hows the lag on it does start spooling up around 3500 -4000 and them wham hello im here at 4500?

 

damn i will be doing this someday.....................................
hey if i put an intake on my car without a tune does it throw a cel...
also just the upper intercooler pipe with a bov does that throw a cel

 

spool is crazy at first. but you shift into the peak power. which is FUN!

if an intake is done right it will not throw cels
an aftermarket bov may throw a bypass valve dtc.
do these mods and get a tune so you can just any unwanted codes.

more to come!

 

Any plans to take your rev limiter higher?

 

geez lol dust that computer screen off, awsome numbers tho get that thing to the track so we can see some new 1/4 times

 

decent numbers...ehh....

but holly hell man, your cam timeing and spark tables must be all OEM, or worse!

that boost response is garbage.

that thing spools like my full T4 60-1, and your about 2000 revs short of my limiter.

i'd get back to busting ass on the tune of that car, the "dev" 35r cars came up quicker then that.

your well on your way, but that's a huge chunk of torque your missing. and mid-range power.

good luck.

 

Just realized that you and I are gonna be running the same turbo. Spring time face off!

Also... I see you dyno'd at Slowmotion. That where I dyno'd mine when I was S/C'd.

 

hows the car on putting that power to the ground

 

cam timing has done nothing to speak of for my spool. (even talked with steve on it and he said it will make min. change)

spark timing is up only where the car wanted it. (if it made power at 5k with 2 degrees then another 2 degrees was added there. the table was changed as a whole for the first 3 degrees and then timing was added at each point where the car wanted it.)
(you keep bashing the way the car is spooling etc.... but give no recom........) any ideas? the .63 a/r might be part of the problem with spool...
the car in that run was blowing spark on the top end. thats why you see a little dip I have new plugs in and I'm ready to go back and finish this thing.
Thanks for looking!

I have no traction till about 70 lol. I have my m/t to take car of that. 90 roll anyone? lol
The dyno sheet was in a plastic cover sry.
I will be going back early march. track opens up the 28th of feb.

 

when are you gonna stop running the stock exhaust??? I wanna see the REAL spool up time?

 

X2.
The stock catback flows pretty well but with your turbo swap you are probably 40lbs/min+ airflow which is 520+ CFM. The stock catback was shown by CIA to flow around 470CFM so you are holding that turbo back at this point. You should gain close to 20whp and reduce your spoolup time by at least a few hundred rpms with a full 3" catback.

 

wait he's on full stock DP and catback?... well that explains some lol

i'm still going to agree with 06black though there's gotta be something adjusted with that tune even on stock exhaust that spool isn't what it should be

 

Synapse made some great gains by adjusting cam timing, anywhere from 400-600 rpm quicker spool https://www.cobaltss.net/forums/show...1&postcount=91

 

no the car now has the dejon 3in downpipe with dump. the dump was open during the dyno pulls.
those in the know need to speak up. becuase myself and 2 other tuners have played with cam timing with no change. I also have westers cam tables for the 16g swap and it made no diff.

Synapse is running their car in 3rd. my pulls are in 4th which will change the way the car spools due to gear ratio etc.....

 

Any plans to rev higher?

 

You have more engine load in 4th gear than 3rd.

 

only in upper rpm and more so when going down the road.

I have done testing in 3rd. I know what the car does. and it spools faster. but for tuning purposes all result are compared to each other in 4th.

^^you really are fixed on that huh?

there is bigger fish to fry, than just revving higher

 

I understand that, I just don't understand why he wont reply to me. He could at least acknowledge me and tell me to go to hell or something.

 

IIRC, to rev much higher than 6500... the injectors will need to be changed - as they will not be able to spray fast enough to keep up.

 

Oops, I did not know that you running you exhast dumped not through the stock catback. It must be your .63 A/R housing then If you have already tried advancing the intake cam warm table a few degrees in the 2800 rpm and up columns and that had no effect. Doing that usually has some effect because the intake valves open a little sooner and allow each cylinder to take a little bigger breath with in turn means more exhasut gas avaliable to spin the exhaust wheel faster at a lower rpm. Your car is just not sending enough exhaust gas through the wheel to spin it up. I think we need a solution for the injector problems at above 6500 RPMs. Then you can rev higher and take advantage of that big turbo. I would imagine it will make peak hp on a 2.0L motor at at least 7000 rpms.

 

then this Steve you speak of is an idiot.

any person for that matter, who thinks they have the knowledge to comment on the tune of this motor all while saying that cam timeing (phase) will have little to know effect on boost response is part of the growing group of people whom need to stop talking. educate ones self.

cam phase dictates air flow across the head, manipulate this to achieve max cylinder fill while running a late spark event along with the ext valves open will jump egt's witch will in turn add to boost response in a vary quick manor.

as for suggestions, its not my job to fix your set up. i engineered mine for a good long while, and its delivered amazing results.

i suggest you do the same. educate ones self for best results. relaying on other people will get you mixed reviews and an uncertain future.

your hotside is NOT the issue. that's a tiny guy.

I'D START PLAYING WITH THE BASICS!

one or the other at first. cam or spark. spark is harder to **** up thus start there.

bump mid range to get the cylinder pressure up to make more off boost power then start playing around with big lumps eaither positive or negative at the transition point.

work it out from there, then go to cam.
yes, the higher the gear, the more engine load, the QUICKER the turbo will spool.

all other things being equal.
