all right. So today (firday) i went to the FactorXEngeneering to tune my car.
LITTLE REMINDER OF MY TURBO TUNING DONE SO FAR ( back from cople moths ago) :
6 months ago my galant was pushing 140 whp at the DYNOJET dyno chase .
I was really disaponted back then, i was about to gave up on my galant - I put so much money for 40 whp gain (basline at 100whp stock).
Well, so i driving like this for about 4 months, till i went on the dyno again to see my air to fuel ratio (they tested it on wide band 0 2 sensors). No mather what i did, the power wasn't comming up, even with max out 550 cc injectors...I found out back then that i am running extremly lean and was really pissed off. I had injectors switch 2 times already and nothing. The
SO WHAT HAPPENED TODAY AT THE DYNO???
As of today, I didn't do any other mods ever since i dynoed my car 6 months, except for one thing that was fucking me up all the time - injectors. I had 310 cc all the time in my car, thinking i had some 550cc!!!!
The reason why i had those 310cc was - one of the guys who ordered the injectors chose a wrong fucking part number. That shit casued me to sped a lot of money to see wtf was wrong with my fuel system
I had my warlbo 255 fuel pump taken out and rewired, and i even thought my vortech fmu is a pos.
However, the whole time I was running 310 cc on my car and that was a big problem that i had.
We decided a week ago that we will put my injectors to check the part number again just to make sure....So we did.
Denso part number indicatd 310 cc injectors, not 550 cc.
I did some more research and i quickly find out that running 550 cc injectors would be too big for my setup.
As of today i switched my inectors to denso 460 cc high imp. injectors.
Took it to the factorxengeneering shop to get it tuned - some client of theirs convinced me to do that. Mike was the tuner there. He is a cool guy i gotta say. He has serious experience as a tuner,engine builder mechanic, and racer. The shop looks very professional, the place is vey clean, they have fabrication room in there, engine building area room, 2 hydraulic lifting racks, some awesome big making hp cars there, lots of tuning tools and of course DynpackDyno Chases.
So i found out 2 vit things at the dyno.
1. MY pipie going from the filter, through mass air sensor, then agian a clamp, piece of pipe and a clam is realy restrictive.
I need to chane it ASAP to get better hp numbers.
2. My boost is only 4.5 psi at the time, even though my autometer shows 5 -6 psi. Yes, i have a little boost creep (.5 psi after 4000 rpm).
So the autometer gauge is off by 1 psi, according to their computerized coneccted one.
Well, folks that's not all. Mike did an excellent job on tuning my SAFC. He tuned all the RPM band past 3000 RPM at 12.2 air to fuel ratio, using dynapck wide band o2 sensors.
I am rich finally, and my EGT temps don't go more than 1470 F at WOT for a long time of driving it.
O.K. Here are some numbers for u, i will post the pics of dyno sheet as soon as i get them from leo, who already took the pics with his digital camera.
i did six runs there. ALL THE RUNS AT 4.5 PSI ONLY!!!!!!!!!!!!!!!
STANDARD HP IS : 181 whp
at MPH: 89
at RPM: 5762
TORQUE: 165 FT/LB ath the wheels
at mph 69
at rpm 4504
THE estimated hp at the crank is 235 hp. Not bad for 4.5 psi turbo galant 4 cylinder.
NOTE: All the runs were taking at 4.5 psi only.
Dynapack is a very expensive dyno chase that proved accuracy and precision over popular dynojet. The hp and ft/lb numbers on dynapack are lower than the ones on dynojet. This is due to the wheels inertia.
In other words, dynojet wheel hp # is higher (overestimated) over dynapck (hp #s are lower about 8 % than the one on dynojet).
Once i will tune my car at 7 psi safely, i will tune it at dynapack and take it later for a baseline on the dynojet to see the differnce in whp without changing anything.
Here is an example how the dynos compare to their whp reeding on WRX.

Another example taken from LAs Vgeas is evospeed eclipse FWD. The car did 475 whp at the dynapack, taken 20 mintues later after cooloff to dynojet dyno without any changes the car was making 525 whp.
MY PERSONAL EXPERIENCE AND THOUGHTS:
The car really feels strong in 3 rd and 4 gear. LOts of top end, safe EGT temp even for running and getting on it for a long time.
Though 1 thing that pisses me off is our auto tranny. The first gear is really weak, and turbo kicks in at about 2900 rpm.
The car starts to acctualy accelerate in the 2nd, but my low rpms (1thru 3k) really suck. Once the turbo kicks in though this is where the car is making power.
The thirs is very strong now, i would say this is my stonget gear of all of them, perhaps because it was tuned in the third...
I don't know what my quarter mile time is, but i know my 60 footer would probably be bad, because of my auto tranny.
I wish i had at least bullet proof it so i can boost it 12 psi safely https://www.thegalantcenter.org/style_emoticons/default/smile.gif
LAST THING TO SAY IS:
I just got my Greddy Manual boost controler, but haven't put it on yet, so once i do and save some money again - i will go back to the dyno and defeniately crank the boost to 7psi, then tune it again, and it should make over 200 whp on dynapcak easly.
I will let u know.
I love the turbos and their possibilties to tune and crank the boost!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :wink: https://www.thegalantcenter.org/style_emoticons/default/smile.gif https://www.thegalantcenter.org/style_emoticons/default/biggrin.gif
