my vtec lags when it kucks in at 5600, what could it be? is it cause im running stock LS Throttle body, or cause im running stock header on a built head, im running typeR cams and was expecting better, any help would be appreciated, thanks.

 

well are you running a stock exhaust because i was running mine (civic) with my b16a with a jg head and it bogged. It toke me a while to figure it out it was my stock exhaust.. try disconnecting the header from the exhaust and see if it runs better.......peace

 

oooook
heres a tip
whenever your asking for tech advice
post the following
what motor
what mods
when did it start happening
did you do anything recently
and what car.

 

thank you, I was just about to say that

look at your oil levels.

 

and WTF do you mean lag?
dosent turn on?
when it turns on it KICKS?
what ecu also

 

it either turns on, or doesn't. it turns on at a programmed (stock ecu or user-programmed), or it doesn't at all.

if it "lags", there must have been a setting changed manually, otherwise, on or off at a certain rpm.

 

sorry, here are my mods
B16 head
PnP
valve jov
itr valves and valve train
crower retainers
itr cams
itr manifold
b18A block
itr pistons
shootpeened rods
i got stock intake, stock header and stock piping, im gonna change my piping and get my cat gutted. did also mention im running a stock LS Throttle Body.

 

oh yeah and Skunk2 ecu, when vtec kicks in it feels the same when your running non vtec, im running a DC2 chassis.

 

hi i have a b18c1 with skunk 2 valvetrain skunk 2 stage 2 cams je pistons and eagle rod 310cc injectors and hondata 2 and skunk 2 cam gears i brought the car to get dynoyed and it made a disgusting 160 whp and 120 trq the vtec engages because it make the noise but on the dyno it falls on its face making nno power???? if you figure out ur problem please give me a shout thanks

 

for the guy that has a lag when vtec is engaged. 5600 is good for type-r cams . check the timing (on the belt) also check the fuel pressure sounds like its lean.

 

I'm thinking its because you have a PnP head, but running a stock exhaust? The PnP is tuned for high flow, but your exhaust is keeping all the gasses stuck in your engine making it harder to breathe fresh air.

 

Are you just running the stock Fuel setup? I vote- going LEAN, get a Walbro lp intank.
Your header/exhaust probably isn't helping much either.

 

i second that. fuel pressure is a must. set to say 44 with fuel vacumm line on.

 

I had a similar issue with a JUN set up, I turned up the FPR and the hole went away!!!
