Ok here is the deal, now im not sure if my stock Civic EX(99) exhaust piping is killing it or what, but this is weird
Dynoed with
97 B18C1
P28 OBD1 chipped with OEM ITR proggy
Skunk2 IM
ITR cams
ITR pistons
ITR valvetrain
AEM CAI (3")
The rest is stock

The guy said im running too rich and need to advance my timming

Any ideas? Can exhuast really kill so much power, i mean stock GSR could probably output more?
I did compression test too before i went to the dyno, and it did 250 all four( NO IDEA what it is so high, even the techs @ honda were suprised)
Im doing Hondata as soon as my JDM DC header comes in ( Back ordered) with Toda cam gears, Greddy EVO 2 70 mm pipin,g 2,5 inch cat, AEM FPR and AEM Fuel Rail...........


I hope it will perform better

 

whoa.....those numbers are super low......

 

my thoughts exactly...........

 

Could be, a small exhaust is basicly like asking you to take a big break and then telling you to exhale thro a straw after you been running around. Its just not gonna work to well, Get a bigger exhaust

 

 

looks its a true stunna!

# look bad man

 

I know HELP ME
what could possible be wrong?

 

check the comp on the motor make sure it's still good

those are like i/h b16a2 numbers

does ur block say b16a2 on it LOL

 

haha


Im really confused though
Doesnt seem like there is anything wrong with a car........

 

a/f ?

 

Im sure you Used .25 OS pistons and re-bored/honed your block? Along with new Bearings, etc....

If your going to rebuild your engine, Do it right the first time or pay for it later!

And honestly Those numbers are not really too too bad....Just figure a stock ITR would only make a little more power, and thats basically what you have now, other then the fact your head is not as good!

Try getting larger exhaust/no cat, etc... You will gain more power!

Well as i mentioned be4 i got everything ready except Header is back ordered

Its just i thought itll put out more, thats all

Can wait till i get Hondata ad tune this sucker

 

Those numbers ******* blow dude. I hit a 153whp with my STOCK GSR in my civic (all it had was a cheap *** CAI, 4-1header, and 2.25 exhaust)

Get that exhaust opened up and youll see a difference im sure, but something isnt right with those numbers. Was this a tune or just a base dyno?

 

No Tune
just basic run
After the engine was build with ITR parts, it was never tuned either

 

what was your timing at, especially on the program???? it dependa also how much timing the programmer removed around the vtec area

I made 147whp with an I/H/C/E B16A2, lower torque of course (106.9) but still, higher peak horsepower. Not trying to disagree just providing some info

Denis Si: Post your A/F chart if you have it.

 

dude.....HAVE YOUR CAR TUNED!!!!!
you should be pushing close to 200whp

 

If i were you i would def get a nice header, 2.5 inch exhaust, new spark plugs if they're old, bigger injectors, get that GSR fuel pump along w/ that motor, and HONDATA....ASAP!!!

Get that timing fixed too. Maybe it's way off???

This should take care of it hopefully.

 

I'm almost for certain it was the pistons.

my stock itr made 175 125

 

yes your stock EX exhaust is choking you. i dont know how much bigger an ex exhaust is compared to a LX/Dx/Vx exhaust, but im sure it cant be much bigger. i saw a stock GSR dyno with lower numbers than you have. 132 with the LX/Dx/Vx exhaust. then the apexi n1 brought it up to 153. get an aftermarket exhaust, and you will gain 20 or more whp for sure.

Good for you...

I have seen with my Own Eyes Some ITRs Dyno Mid 150s!

Eric

 

im not bragging. im saying his engine did not put out a properly built itr's output. not even close

to add to this. ive seen a stock itr put 183 with a header, exhaust, fpr, and a comptech cai. he also had the front bumper removed, so that may have added 1-2 hp
