hi

What boost is everyone running with the C30 kit? what is the size of the compressor drive pulley (to see if we might have the wrong pulley)

I'm not enterirely sure but it looks our C30 kit is boosting to 1.35bar?!
We have the C30 kit with toothed pulleys
denso 2.5bar map sensor
sard decat exhaust manifold
stock overpipe
sard catted front pipe
milltek resonated catback
OFT with our custom developped map (in progress)

stationairy our map sensor reads 0.06 kpa so it seems to run just over atmospherical pressure even stationairy, then pulls upto 135 kpa at just 5500rpm where we ran out of fuel, DI fuel is at 100% / 20Mpa and port injection is also at about 96% ??? fuelpump duty is at around 86-90% or is 135 just 0.35bar?

it is very weird we cannot get it rich enouh while everyone else runs at stock fuel system? either way we are running to lean. from about 5000rpm upwards

we have fuelpump and 650cc deatschwerks injectors waiting to go in now, but we worry about 1.35 bar on a stock engine (we just blew the stock headgaskets at 5000rpm) so i want to make sure 100% we have the right pulley or maybe our map sensor reads wrong

we have the following settings for the honda/denso map sensor in our oft:
multiplier: 0.367
offset: -0.045

this is a screenshot of a log we made, look at the fuel data and map reading.

any info on pulley size or max boost please?

I believe im seeing around 0.79bar with the old design 75mm pulley.

ST-A · 03-01-2015, 05:30 AM

this is a log from before we upgraded the map sensor

clearly too lean, wa can't get rich enough, but we only could read 0.4bar on the stock map sensor so we upraded it.

Has anyone had the tensioner slider (black piece) freeze up on them? I went to readjust the belt the other day and couldn't move it.

Loosen the nut on the back of the tensioner and it should dislodge with a little nudge.

is an oil cooler a must for normal DD with no track use??

Been running my kit without one for over 10k miles and haven't noticed anything bad so far

Nope.

I'm not going to be running one when I do my SC install in a couple weeks. The temps here in Canada are a definitely a bit cooler than the us. I'm sure if you have the money it's a good investment however I'm going to run without one for a bit and just monitor oil temps and see how it goes. My car will be a dd and likely not see the track

I don't see why not, 1 smooth pulley is better that 3 (noise wise)

But you could just wait for a bit, KW has really good support and they will take care of you. You might also want to make a video to show that your bearing is screwed and send to them.

That's the way it should be done all the time anyways.

Maybe it isn't a nut but it is the actual bolt that goes through the KW idler pulley and threads onto the tensioner. You will have to remove your intake piping to get at it easier.
