Evo 9 SSL - BR 2.3L Oldschool AMS 3586R kit S2 cams E85 & 93 | 700WHP+
Sharing Anthony's car again like we did last year. This year he decided to do an E85 tune with a new Buschur 2.3L engine. My personal goal for his car was 700WHP~. This is not easy to do with a small .63 AR hotside that is restricting top end power. I told anthony this, and he was well aware the AMS kit spools very quick for a 3586R because of its restrictive hotside which sacrifices top end.
The boost curve always has a funky dip in it. it had a hump last year. also. not sure why this car does this. its the only ecu boost car ive tuned that does this on stock ecu.
I will have him look into the external wastegate for possible issues.
The 93oct tune we completed in just two pulls. he did not want anything aggressive on that, so we just ran off wastegate pressure for that and had it completed in two pulls.
Fueling: E85 & 93oct
Temps: 72F outside
Mods:
Evo 9 SSL
BR 2.3L
BR double pumper
BR exhaust
BR Ported intake manifold
AMS HTA86 (oldschool hotside .63 AR)
Exedy Triple HD
FIC 2150cc
MilSpec 65MM TB
GSC S2
ETS intercooler
ETS licp
STM uicp
ARP L19
Tial 50mm
Grimmspeed 3 port
SpoolinUp COP
Tephra v7 SD /w ecuboost (4bar / gm ait)
E85: (I could have filled that dip in mid range boost and opened up way more tq but i asked Anthony if he could feel it, and he said no, then i asked do you want more tq in there? He said no, it already scares me lol. so we left it weird like that) <-- lol just explaining the goofy boost curve.
Quick 93 tune (wastegate pressure):
downlow a bit i richened afr alittle more, other then that thats where we left the 93. very conservative. 3 port made that hump by itself also.

So far, this car screams in 3rd! I havnt done a pull in any other gear, but this thing spools so fast for the turbo, makes for a very fast, fun street car!
Cant wait for the shootout! Im really hoping I can barrow my new father in laws truck and a trailer so I can really beat up on the car all weekend without any worries of getting home, 8hrs away lol. Finally get to try my qtps!
If I dont tow it, I dont know that I will race at all lol.

we still need to see whats causing the boost curve issue and also was a slight false knock issue at lower rpm that i didn't take care of yet because i'm curious what was causing it. i confirmed it was false though. kept removing a degree and it kept going more lower and lower each time with loss of power.
aside from those two things, once its fixed car will be 100%. hopefully its just the wastegate causing the weird boost curve. this is the only car i've ever done that did that with a 3 port before.

let me know when you check the wastegate. that boost curve annoys me just looking at it.

but do keep in mind thats 40-42psi at redline! so the small A/R is definitely hurting power up top.
The upper pipe? short route? it hits the body? if so i had that happen to me before also. it can also hit the engine mount stud on trans that the moun slides over. i bet thats where its coming from. also could be a heatshield somewhere at downpipe area or downpipe touching oil pan etc.

Ok guys, looking for a little insight here. I just pulled the tial 38mm off. Took it apart, sliced my thumb up in the mean time on the dam thing! Anyways, it looks completely fine. I have a small blue, large blue spring combo in it. I didnt see anything out of the ordinary that would look like a problem to me.
I havnt done a boost leak test for a week, but when I did it last, there were no leaks to be found. Trying to diagnose this funky boost curve dip my car has. I cant feel it in the car, but the dyno shows its there.
Im starting to wonder if its just a small boost spike, since im running the smaller .63 housing?
Suggestions?

The last rom i sent will address some of the boost droppage. since you have confirmed the WGA was ok and everything else looks ok then ill just tune the curve in to be straight.
id guess its from the .63 ar then. i don't see what else it would be.
glad to see the upper pipe adjustments removed our false knock crap though downlow.
