Not enough power...?

[forcdincivic]

okay so after reading a bunch of setups you guys have and ppl from turbod ect....it seems like you guys are all making around 200whp, but i just had my car tuned and dynoed and it made 156 whp which seems low for my setup what do you guys think/suggest i do?

garrett t3/t4 running 8-9 psi
cast iron manifold from godspeed
tial 38mm wastegate
350cc dsm injectors
apexi neo vafc (tuned with wideband)
big front mount ic with 2.5 iinch piping
apexi n1 catback exhaust with highflow cat
hks bov
Stock internals just rebuilt

doesnt that seem a little low for power? I know i need to get a new ecu and im going to get it tuned with chrome but i dont think that will give me another 40whp!

 

[Steven.]

really depends on setups man.

and location also matters

 

[Chris.]

dramatically reduce the size in intercooler. a huge intercooler is where the problem is. you are experiencing boost loss. yea you running 8-9 psi but i bet you can run higher. where do youhave the boostguage reading?

if you run a smaller intercooler you wont see asmuch a drop and make more power

 

[squidmaster]

what engine?
and what size exhaust?
also the tune will get you a good amount, what do you guys say, about 25ish WHP?

 

[Phantom Civic]

As stated a smaller intercooler will help. Most people with stock motors use something like a 6".

What size t3/t4? It will still be a little low but a 48trim, "b" compressor housing, and a small turbine a/r will make for a very small t3/t4.

What type of dyno was this on?

What size exhaust?

Are there very sharp bends in any of the charge pipes, dp, or exhaust? Do you have the stock cat?

etc. etc. etc.

Hope I helped some.

 

[forcdincivic]

ok....so let me see if i can try and answer all you guy's questions

as for the intercooler, i believe it is a 9x20 (i got the upgrade for free it is rated for like 500hp) so if i up the boost to say 15, does that mean only like 10psi will make it thru the charge pipe?

I have the boost gauge reading from the bov, which is tapped onto the fpr. and its reading 9-10psi (if thats what you meant snake_shit)

For the trim, i will have to check on that i dont remember, i believe it was like a .50 something, but ill get back to you on that tomorrow

The engine is a d16y8 stock internals

There arnt many sharp bends at all, and its all mandrel bent so its real smooth corners, the only thing is everything is 2.5 then the downpipe goes from 2.5 -> 2 inches at the exhaust ( i know that causes some power loss and i should have like a 3inch exhaust but it shouldnt be THAT dramatic) And i have a highflow cat like i said above, i want to do a test pipe though

and the dyno wasnt a dynojet, the guy said that dynojet numbers are normally increased by about 20% so my car would have read like 180whp on one of those, but i forget what dyno he used, the day he tuned it, it was fairly hot out and pretty f**king humid too which i know has something to do with it, so I guess i should just get a p28 obd1 ecu with chrome and have him tune that and go from there? It just sucks with all this money into it that I seem to be making less hp then most of you guys with a fairly similar setup, so let me know what you guys think, maybe i should turn the boost up a little, idk feel free to add/ask anything

 

[squidmaster]

yeah new ECU
and dyno again on a cooler day or something.
also try running a 3" exhaust
but as stated many times, until you get new internals and pump that boost to like 30psi it's just going to lag you down.

 

[Coutts]

dont go too crazy on the boost, the stock internals are only rated to 220whp before the rods snap, so keep it below like 210 and you should be safe. Slowly adjust the boost, dont just up it 5lbs and take it to a dyno as you might have turned it up too much. i dont have a turbo car or anything, im just stating common sense things to be safe.

 

[ryan89crx]

your exhaust is holding you back severely. upgrade to 2.5" mandrel or 3" and you will see significant gains

you will also benefit from a chipped ecu and custom tune

 

[majorahole]

first, your injectors are limiting you, secondly your ability to tune with the v-afc, chipped ecu is where its at.
f**k getting a smaller intercooler of bigger diameter exhaust. that apexi is the same that i have.

most likly that turbo is big enough. your boost gauge is at the bov??? you mean tee'd into the same line?? i would get it as close to the intake manifold as possible, for the most accuracy

 

[forcdincivic]

yes its t'd off the bov, and yes i know i need to get a new ecu when i have the money....and i dont think my injecctors are limiting me, i mean 450ccs should be plenty at 9psi, i do need to get a walboro fuel pump though


and yeah no s**t im not gunna just crank up 10lbs of boost lol, i would do it when i have it on the dyno just to be safe...

and i mean yes eventually i want to get a bigger exhaust, but like i said before i dont think that it would really cause like 40whp power loss? Im not trying to say you guys or wrong or be a d**k to anyone cuz u guys all have different opinions as to why or what would be better, so thats why im asking, its always good to have input and to see what my options even are

 

[wizard]

it's in the ECU really for sure i had an already chipped one from phearable and it ran good but a little rich so i just saved and got the s300 and it runs hella better......

my little y8 is puttin out 242 whp sholud i detune a lttle turn down the boost ETC....

are you running stock internals or built?

 

[forcdincivic]

thanks ill def. get the ecu...and yes i have read everywhere, turbod16, homemadeturbo, hondatech, etc, that you shouldnt push any more then 220whp on stock internals and rougly no more then 10psi

 

[Coutts]

http://en.wikipedia.org/wiki/Honda_D_engine i learned about it from that. btw the connecting rods will usually withstand 220bhp, not whp.

 

[wizard]

i'm only running 8.5 to 9 lbs on stock internals

if you're making more than 220bhp, tune that s**t down immediately or build your engine.

 

[TiiM iiS l3eAsT]

your not just going to blow your motor cause your running more than 220hp......their is ppl over at turbod16.com running 12psi making 242whp on his stock d series and its doing just fine.....220 hp is just a rating to be safe at.....i would say d series will go at around 250 hp.....just my opinion though

the dsm 450cc injectors are good to 300 hp, so that shouldnt be a issue ....also you dont need a new fuel pump.....the stock fuel pump can handle 250+ hp......

i would get a new catback.....atleast 2.5"

on 8 lbs on a t3/t4 you should be making around 180-190 hp.....i would run 10 lbs and call it quits.....plus the stock MAP can only tune up to like 11 psi

 

[slowcivic E G]

id say if you get rid of the cat and go to a straight pipe and maybe a bit bigger exhaust and a tune you will see a good power increase.

but why would you ever even think about going outside the safety range especially with how unreliable a turbo car can be sometimes. Sure it'l run fine for now but hes prone to throw sooner or later at that rate, much faster than someone only making 220hp. Keep it below 220 unless you have the funds and the knoledge to be replacing motors over and over.
