heres the setup,

b16a obd0 pr3 ecu, hasport wiring kit, hasport mounts

approx stock dist, timing.

walbro 255 pump

12:1 vortech fmu

sohc greddy kit, 15g, dsm smic running stock 5.5 psi

msd sport compact ignition

ngk 7 series gapped to .35

msd 8mm wires

2 1/2 inch exhaust, no cat

155whp 138 ft. lbs of torque

my a/f went from about 4k 12.1 straight to 10.1 all the way to redline. i was boosting 5.5 , and i lost almost two pounds of boost by redline.

the future holds a mbc, a safc 2 fuel controller, big injectors, and more boost. but for now i want to see if i could do anything to pull any power out? do i want to play with timing? off the distributor? or what? i dont know what else i can do. before i spend big bucks on this car.

wwow, that is disappoiinting. i would cry if i were you. my stock gsr makes that.

did you do a compression test??

Yeah i would start the with the base of it all, find out if your motor is 100%, and then go from there.

Rob Dizzle

most likely something is wrong wiht the motor or the fuel or timing is way off

its prolly not because you need more boost

you could have bent valves or something

NotPhilTran

i might just have a pressure leak somewhere too.....

COOKIEPUSS

I would do a compression test
Post dyno w/ A/F Curve
Close the plugs to .028 (double check this w/ someonelse to be safe)
Check for boost leaks

NotPhilTran

woont gapping my plugs tighter make me run richer?

im already hitting 10.:1 a/f

BoostedsiR

get rid of that bullshit setup get hondata, I hate seeing all these people trying to run SOHC kits on a DOHC get it right, I understand you want things done cheaply but your mani is extremely important to the whole turbo setup and having a weaker sohc mani on there wont help flow and the b 16 really doesnt have the best exhaust flow.

gdrum

get uberdata !!!!

FuriousGeorge

Gap your plugs to .030
What disc are you using in your FMU? Maybe a 12:1 is too rich for you, switch it out for an 8:1

I don't think you can put a SOHC manifold on a B16.

Anyways, I have a B16 turbo in my CRX and it was running on 3 cylinder ($3 at 90psi) and it still ran hard as hell. I am using the VAFC Hack with MSD BTM.

Do you smell oil when you drive??? do you see white smoke coming out of your valve cover?? If yes then do the compression check. Let us know.

Your numbers are bad but don't be sad, at least your car looks good. Unlike my rust bucket.

Oh yeah you can send your ecu to Cheetah to get it done cause I will be sending him mine soon when I have some extra flow.

uberdata is not for everyone, you have to realize that

NotPhilTran

it is a sohc greddy manifold

anyways.. heres what i got as for as answers to my orginal question, other than the negitive comments.....

try changing gaps on plugs
check for boost leaks, and vacuum leaks
do a compression test

any other postive help i can get? thanks guys

That's what your boost taper makes me think. Small boost leaks lead to the compressor overspooling and you heat the charge noticeably, making it much less dense. It also kills turbo life... get on it and fix it pls. Pressure check all components, and don't use a screwdriver to tighten fittings - that is pointless - use a socket and make *sure* they are tight.

You're entirely right. If you'd rather spend a lot more money and a lot more effort to have little to no control of your fuel and ignition, then Uberdata is not for you. Well you can spend even more money than that and get Hyundaidata/EMS that the same person in this example couldn't use anyway, which would perform just as well as cheap old Uberdata.

This isn't an OBD1 application, but allow me to go a little further OT on the subject... FYI, in this case I'd suggest an OBD0 90-91 PS9 or 90-91 PR4 automagic ECU and some turboEDIT boost/one wire VTEC code... you could probably sell the PR3 for what it takes to buy said ECU and chip burner.

Buy a chip burner and roll the software and stuffs into your tuner... if they can fiddle a complex machine like an EMS or have any Hyundaidata experience, they can tune with Uberdata. JDogg, one of the stupider people I know (he's a factory trained EMS tuner, and Prelude/Accord fanboy, therefore completely ignorant), got 198 whp out of a stock H22 with generic filter on a stick and a butchered beat up rig job header on one of his first tuning runs with Uberdata. He had a little tuning experience using other standalones in the past, but as I said he's an idiot so any tuner you pull out of your hat can do at least as well or better.

Damn I just learn something New myself today.

Get rid of that, it has no place in a DOHC B16.

Ri5e

Thats a really now number. My friends RSX makes 185 WHP with just intake

Definetly do a compression check

DaNish

what did you expect with that shitty turbo and weak amount of boost?

AB16A2T

I make like 143.8hp 103.7tq on my almost completely stock B16. All I have is an intake, and exhaust. Something isn't right, do a compression test. Start from there. Should be making a lot more power.

EDIT: Torque is a lot more than a stock B16 though.

Spoken like a years-long subscriber to Stupid Street.

I've seen 200 ft/lbs by 3000 rpm and 180 whp by 5000 rpm on LS at 5.5 psig, with that shitty turbo and that weak amount of boost. If anything, the cfm consumed by a B16 @ 5.5 psig, all other things being the same, should net something fairly decent.

It's also in a CRX, it doesn't take much.

Who did your swap and work on the car??? Where u from ??? Let me know

Mr. Softee

check ignition / cam timing. repeat dyno.

explain a "weaker Sohc Mani" ....I dont' think his problem is the Mani, the turbo..or the exhaust flow of a b16a...there is somehting with his motor or tuning (lack of).. Ive seen similar numbers with the same kit on a d16 @ the same boost. Something isn't right, but he doesn't need a blinging manifold or oversized turbo to fix it
