Your boost level should be close to a GSRs (same displacement). Stock crank, stepper, and 3.8 pulley is around 9.5psi. Camshaft type and timing, intake, and exhaust setups will play with it.

ie: with stock cam timing on a stock ITR you are likely to get a little less due to excess valve overlap.

I recommend listening to Jadkar's suggestions on max boost levels.

what's strange is that my B16 w/CTR cams on stock cam timing, stock crank, 4.2 nose and no stepper runs 7psi all day

figure that one out

??

Veris

Not so strange. A b16a should run ~7psi with standard pulleys.

Camshafts will make a little difference on boost detected like exhaust, intake, and head design (porting, etc) but we generally aren't talking huge differences. Boost is basically just a measurement of air restriction.

Just a question about pulleys and boost.. im going to be running a crv crank, the 4.0 blower pulley and the mvm stepper im looking for around 12 psi?? would i be correct in this assumption. ??? currently runing 8.9psi exactly with the 4.0 nose and the crv crank, on an ls vtec

Hey Nextproject can you get some pictures of your setup posted? I wanna see that beaut

I had a few questions i just got my whole B18c-R JRSC all done, My question is the pulley on the blower seems to shake back and forth when the car is running at idle when you give it gas it looks as if it goes away, also the pulley has a few chips on the outside so i was thinking maybe thats what making it look like its shaking. Thats my first question.

Second i have the stock ITR crank pulley on the car a 4.2 blower pulley and the MVM stepper pulley and the car only made 7psi of boost on the hondata dose this not seem a bit low? On the dyno the car made 217whp and 156Tq dose this also not seem low for 7psi on a ITR? My meth injection kit also did not gain me any power even with the timing set to 24 degrees Snow performance said this is because the blower is not boosting enough were the heat is becoming a problem, also referred it to a car running on race gas that dose not need it.

Any input would be great i wana drive this thing but this whole blower pulley shake scares me.

I'll take some pics this weekend and post them I've been very busy lately and haven't had a chance to take any pics of the set up

2nd q, answer.
seems about right to me.
I have about the same set up and made the same power (minus 5-10 or so Tq) @ the same PSI. What I noticed during my runs is that heat DOES affect the power made, and my tuner also mentioned it to me. Thats why LHT is a +.... The only thing I dont have is the meth inject. I would imagine it should cool down the IATs and produce a little more (which it did, on the tq side?).

someone correct me if I'm wrong.

boost it up !!

Veris

Sounds about right to me.

It'll be on the hight side without any intercooling.

selling this kit for my buddy came off a b20v said to make over 300whp comes with whats shown 1900 obo 1800 local pickup

MyLilCivic

Well it made the same horsepower on and off the meth no gains at all with the meth idk why.

What about my first question why is my blower pulley look like its shaking everything is tight...???

Dumplestiltskin.

Is the pulley tight? Does it look like its shaking from the nose shaft or the pulley itself?

MyLilCivic

Looks like more the pulley and when you give it gas it seems to go away but at idel it shakes

Dumplestiltskin.

I had the same problem when I first started mine, but at the stepper...kept jumping belts too.

1. My belt alignment was off.
2. My alt stepper pulley wasnt tightened enough before installing (took me ~2hrs to take that sob out to tighten it).

I have a question for everyone about the map sensor. I know that for the map to see boost, you have to nipple it to the manifold. Im planning on getting a 3bar, so is there any reason to purchase the hondata map bypass?

jdm_integsr

B20 Crank Pulley For Sale. I dont know how much I should ask for it... anyone interested?
Also, for the CA people, I have a Jackson Racing CARB Sticker...

i have a built gsr with a jr on the stock pulley system and when i went to get tuned the guy that tuned it said it made power till 9500 rmps i seen the dyno graph and it does. my question is, is it safe to rev the charger that high ? i know the motor can handle it but not sure bout the charger.

jfruauff

Crank pulleys usually go for 30-40 bucks. I am interested pm me a price shipped to floida and a paypal address so I can pay...

jfruauff

I dont think the few hp is worth the strain on the motor. Built or not 10k is one hell of a rev.

jfruauff

Sorry for the repeat posting,lol.

I plan on running a stock jrsc kit with a ls pulley on my gsr at 7.5 psi.Which is where I feel safe. I have plan on using 510cc injectors and crome to tune. Do you guys think I need a aftermarket fuel regulator or will a stocker be fine. I have both but Ill have to do some work to make aem one fit.

tegdude227

no i know i just just woundering if the charger could be harmed from doing this ?

rmcdaniels

Stock FPR should be fine.

jfruauff

anyone have a 4.2 charger pulley?? I have a 4.0 I could trade or ill buy the 4.2.

nextproject97

finally had a chance to take some pics of my set up here they are 260hp 206 trq

jadkar

Very clean buddy!! Do you have a shot stading in front of the engine? And is that the new LHT design or is it someone else's?

God I envy you guys withthe Tegs and all that room up near the firewall!
