well, it might be more than 5 hp but its not a lot. i took off my bumper and checked for boost leaks. didnt find any. i switched boost gauges and found out that i am not even running 3psi... running about 2.8psi-2.9psi with an initial spike to 3.5psi. it feels strong but falls flat on its face... maybe that strong feeling i get is the 3.5psi so i think im going to up the boost to 5.5psi and see how strong the car feels from there.

btw, i have a weird squeaking sound, it happens a lot when im on rough roads... it could be a belt.. a friend suggested maybe a broken motor mount? would a broken motor mount squeak?

u sure your cat isn't clogged? take your downpipe off and roar down the street once or twice.

sushibug

i should huh? maybe i'll do that and see if my boost reading changes... right now i gotta go meet up with some friends, go watch spiderman, and meet up with a fellow honda-tech member to pick up some goods. man great deals all over the place at honda-tech!!

this place sooooooo owns!

where in sd are u? I'd like to check out your setup. I'm in the La Jolla area.

wow more san diego people, cool.

Dude, what are you running for boost controll? Stock actuator/wastegate on the GReddy turbo? If so, then I already went through what you're going through now. When I first istalled my turbo, it'd feel great in 1st and ok in 2nd, dead flat in 3rd, almost stock like. But thenm I was geting 2.5-3psi max because of the front mount.. get a cheapie manual controller and bump it up a couple psi, see how she feels then.

This is assuming of course you have absolultey no leaks whatsoever..

Make sure you run the vacuum line to the actuator from a source on the manifold, and plug the port on the turbo. It should hold boost fine then.

When I just connect the line from the port on the turbo to the actuator like how it comes from greddy, it just spikes off of 5 psi and then falls to 2.5-3 psi. But hooked up like mentioned above, it holds 5 psi perfectly.

****!!! this is probably the problem!!! im going to go do this in a hour... this is it baby..

i live in el cajon, you can get a ride as soon as i know im a 13 second car.

oh my

sushibug

after driving my car with the vacuum line from the wastegate routed to where my boost gauge was hooked up, i noticed a small increase in power. it just might of been wishful thinking. can anyone tell me if 2psi more is a great difference in power? im thinking i need to up the boost.

JFK78

You should definitely feel 2 more psi. Did you buy your kit used? If so then someone probably messed with the actuator arm. If you're still not getting 5.5-6 psi then I would shorten up the actuator arm to raise the boost.

sushibug

i would but someone told me that it isnt a good idea to mess with it because you can not get it back to the same setting again. vtc_civic was saying that he also had 3psi with a similar setup. so i dont think anything is wrong other than theres a 2.5psi pressure drop w/ my intercooler. i would like to note that my auto tech teacher tested out my wastegate to see when it opened at. (5.5psi)

sushibug

okay guys.. after talking to my friends i figured it out... and realized i mised something before. the vacuum line from the wastegate that connects to the turbo... it is reading pressurized air before the intercooler... so thus it is opening at 5.5psi but not compensating for the 2.5psi pressure drop. by tapping into a vacuum line at the intake manifold, we were able to read the true manifold pressure. (problem is that we didnt have the extra vacuum line so we had to take it from the boost gauge) so we dont actually know if we hit 5+psi but i am guessing we are. BECAUSE: my stock fuel pump can no longer compensate for the additional fuel pressure. my a/f readout shows rich but soon as it hits 4-5psi it gets not lean.. but stoich... im running about 14.2-14.5:1 a/f at max boost. stoich is bad for FI right? so i guess im going to reroute the wastegate line back to the turbo so it doesnt boost more than 3. and get that inline fuel pump i have been meaning to get.

speaking of the inline fuel pump... does anyone run a msd inline fuel pump? 3/8 in. inlet, 5/16 in. outlet, in-line, high pressure, electric... does it matter if the inlet and outlet size are different? that means im going to need a different size hose for one end?

JFK78

That is exactly what I was telling you. If the actuator arm has never been messed with, then it's at 5.5 psi. And you should be holding that just fine with the line routed off of a manifold source after the intercooler. Why don't you just use a T-fitting so that you can hook up the boost gauge again?

I am running the kit like that with the smaller greddy intercooler, and it holds exactly 5 psi.

Yeah, you'd better get a fuel pump, the 14 range is way too lean.

yeah i didnt have a T-fitting at the time. its sunday after all.... i just finished picking up some goods from "Krow" (i bought a cam gear and some other stuff off of him.)
