Here's what my car did at the dyno today. Sorry i gotta run, but i thought you guys might like to see what i put down. If you've got questions you can leave em on the thread or pm me. Laters

-iLLuZioN-B18C1

whats the set up?

nice numbers!

done

such high hp, seems like a low tq...

i guess for a b16 not to bad..

is that vortech supercharger dyno??

blu_si

nope it's turbo for sure.

b16 (forged pistons and rods)
drag kit (swapped in a precision turbine .48/.60)
550cc injectors
2.5"dp flared to 3" the rest of the way out
Hondata 2b

I know the turbo is a Precision.

ekb18c

how many psi?

The_Head

I'm gonna guess thats 14.7 psi...

Did I win?

blu_si

that was at 14.7psi

blu_si

yes you did

The_Head

Awesome! I won!

inspyral

Nice numbers
What's with that dip in the powerband? Is that from VTEC engaging?

keebler65

yeah it looks like it was probably engaged too early or it hasnt been tuned 'perfectly' yet. nice improvement in numbers though

post some pics!!!

nice numbers..quick spooling turbo

blu_si

Yeah i'm not sure what that dip is, but it seems to happen right where vtec kicks in. Not sure why though maybe someone could help me shed some light on that.

TurbothisLS

how much boost

R-1303

the dip is from the cam switching over, it is overlapping so u get a slight dip..no problems just more tunning and you'll get a smooth curve. Nice #'s

blu_si

would some cam gears help smooth out the curve? i plan on puttin in some gsr's and cam gears in the next couple weeks.

How's your A/F? Some guys run a bit lean when their VTEC engages and causes a power dip like that. Good numbers, btw

blu_si

at particular poin my a/f was about 12.7-13.0

Why does it say MAX HP = 301 when the graph shows ~315ish?

inspyral

I think you're looking at the torque curve. If you look at the scale ont he right, that curve lines up with about 215, which is what his max torque is.

i have no idea, damn computers

Try moving the vtec switchover up in a little.
I had my vtec switchover point at 5,200rpm and there was a dip that looked like yours. I was losing 20whp at that point. I moved the vtec point up to 6k rpm and the transition is a lot smoother. I only lose about 3 whp now when it switches over.
6k is a bit high but it works the best for me. The guy who dyno'd my car said that it's a common trait that turbo charged vtec honda's have.

i make 302hp and 251tq with a sohc on stock internals... looks like you need to do some more work..

blu_si

well, my compression is a lot lower than yours is, i'm sure. so, if by work you mean increase displacement and compression than sure, that is my next project. Also, how long do you think your stock internals will last? Cause i know my internals will hold up to that amount of power for quite some time. How often to run at that much boost anyway? daily or was that just your peak hp numbers?
