Alright, i've had this car running for a month or two but i just finally got a copy of the dyno chart on my computer. I'm curious on what all you All Motor Gurus think. Here's the build:

<U>Bottom</U>
B20 block
Wiseco 12.5 High compression pistons
eagle H-beam connecting rods
everything else stock

<U>The Rest</U>
Skunk2 stage 2 cams
Skunk2 adjustable cam gears
Skunk2 titanium retainers
Dual valve springs
AEM Fuel Pressure Regulator
AEM V2 Cold Air Intake
No p/s
No A/c
DC 4-1 Header
2.5" Header back exhaust, no cat, just a resonator
Hondata s100

If i'm forgetting any information, just ask.
I'm really wondering why i have a slight loss of horsepower right before VTEC engages(5500 rpm's) It is noticable while driving the car.

 

which vtec head did u apply? also what size tb are you running with this setup? #'s dont look bad at all

 

Nice power, what type of intake manifold are you using?

 

daily driven pump gas?

 

what throttle body and intake manifold?

 

get better cams with that high compression and header and i bet you make over 230, i had the same build except 11.5 comp and 91 oct. i made 220/156.

 

what head did you use?

also every motor is different,by looking at the graph it looks solid, so thats probably where they made the smoothest crossover point

 

vice nice, a better header would do wonders

 

i know a better header, everyone is telling me that. but in reply to every one else

its a JDM ITR intake manifold with a 68mm TB

440cc Injectors and a walbro 190 pump(i think) maybe the next one up

Its a b16 head

 

What do u guys think of going with ITB's? i have a friend that has some for sale....but i dont have anyone around here that likes tuning ITB's

 

is the tb ported for the im. also i think that motor would love some head porting

 

it looks good to me man but u would have made more power if u went with a pro-series cam over the tuner series cam. and throw the dc header away. thats a serious build u have there. good luck with it

u kinda answered ur own question. if no one is gonna do a good tune with them then dont get them.

you can make power in other areas first

 

itb's are great if you know what your doing,the only way id get them is if i lived in florida and could get donf to tune it

 

is the itr manifold ported ? .. is the b16 head ported ?

 

what about a short ram intake, or a regular CAI over the V2?

 

i ran a 13.9 with street tires that i dropped the air pressure in. remember this car was originaly a 99 si, so its a heavy SOB.... do u think i could get 13.6 or so with slicks or more seat time?

 

with slicks and practice that motor even in a coupe will be in the low 13's in my opinion

 

i say 12s if u drive right

 

STD 84mm bore size?

 

your setup is just like mine.except i dynoed with a ebay intake open header and c16 and made 241 whp 161tq

My 195whp LSVTEC '98 coupe went 13.1 @ 104-105mph on slicks, and 13.8 @ 104mph on street tires.

You should be able to do the same, if not faster.

the header alone might be your only problem.
