Anyway to check the oil in it? Just look in the fill?

by **ASG14** » Sat Oct 25, 2008 12:03 am

You have to take it off to check the oil, or it will spill out.

If a brearing on the SC was going bad, you'd hear it over ALL other engine noise. Eye8Pussies had his SC rebuild earlier this year as a bearing was on it;s way out, and it made a racket of metal on metal sound. but he still made 100% of the boost.

by **Eye8Pussies** » Sat Oct 25, 2008 12:20 am

yup...basically, regardless of whatever's happening with the supercharger, bearings are making noises, etc, the rotors will still be spinning and pushing the air = boost, and due to the design = full boost regardless of all factors.

what COULD affect the boost though, would be if your actuator is in good condition, since it there is something wrong with it, and it's not holding vacuum the way that it should, it won't open up the port inside the suparcharger fully and allow full boost

as for lacking in power....the fact that you blew your knock sensors might point to the fact that you don't have any proper fuel mods in place. if this is indeed the fact, then there is also a chance that your ecu is pulling timing because it is reading knock.

but regardless of whatever case it may be, it is not the fault of the supercharger unless it is seizing up, or, if you have a boost gauge and it is correctly hooked up, it isn't showing any boost- which would, in this particular case, just show that there is most likely something wrong with your actuator

Second you gas it and the actuator loses vacuum and closes the flap... starts sounding like metal on metal. And yes, now that I have the ATS sensors in it isnt retarding my timing and I do still feel boost, just sometimes doesnt feel right, kinda bogging, not missing, like the superchargers putting an extra load on the motor... I really gatta hook up my boost guage already see if it stays at a steady 5.5psi... But yes the car still does feel stronger now that the timing is retarding, still doesnt sound right anymore though. And before the original knock sensors went it felt strong as hell... Pretty weak now at the higher rpm range. Also for the fuel mods, I have had Jims Fuel Mod in since day 2 with the 4psi pulley. The night after I installed the supercharger i put in the fuel mod the next morning. Car runs great at 150k miles.. I mean golden oil still after 2k miles of me gettin on her good. Just wanna fix this once n for all... Takn off the supercharger aint a problem either, I can literally get it off in about 15min, every bolt n bracket.

so you hear bearing noises only in boost? that shouldn't make a difference since the rotors are always spinning regardless of the actuator being open or closed. the only difference is either of the intake air bypassing rotors or going through the rotors, but they're spinning with the engine rpms regardless

as for the lack of power, I'd say that the timing is still be retarded. not much else could do it at this point. the reason behind it is a guess though.

Do you also have a high flow pump?

and the only real way to know is by using a live scanner at this point and seeing what timing is being pulled/added when you boost. also, yes, a boost gauge would be pretty essential at this point of diagnostic's sake

Thanks man.. Yea I need to check it out... The supercharger has no power after 5000rpm so I really got to check the psi gauge... Just something isnt right... And about then it really sounds like the belt is slipping cause it starts screetching like a belt or bad metal on metal sound... I cant tell because its fine at idle, and the belt is pretty tight.. I really cant make it any tighter, unless I get a smaller belt, but feelin it shouldnt really make a difference.

by **20SoLaRa02** » Sun Oct 26, 2008 9:54 pm

i might be lost but when did u switch from 4 psi to 5.5 psi? Did u change ur belt size when u made this change? i believe most people change belt size when going from 4 to 5.5. also are u working with an automatic tensioner?

by **Slut** » Mon Oct 27, 2008 4:29 pm

Im going to try a new smaller belt tomorrow... Can anyone tell me the number of the belt they use for a 5.5 pulley... Also what port on the supercharger see's boost? So I can hook up my boost guage to it. Thanks again for all your help guys. My long term trims are at -7% and at WOT both front o2's are basically at 9mV, so I assume im really not running it lean, Would I need to get a walbro or some sort at 5.5 psi?

You definately need a pump, it's more important that the Jim's fuel upgrade.

by **Slut** » Mon Oct 27, 2008 9:23 pm

Ok so what should I put in... a walbro 190? 255? Im sorry I really dotn know these cars that well I just got it, so I dunno specs on like Fuel Pressure, or what cc's the injectors are.. You need some help with nissans or dsm's with turbo's im your man.. I just didnt think id be running lean with jims fuel mod on 5.5 psi... Ok so what should I get guys... Also I see the regulator is in the tank on our cars? No need to do anything with that right? Also like I said before which nipple do I T off of to read boost... Please let me know bout the fuel setup asap, I guess for the time being if you guys say I might be runnin lean yet my long trims are tryin to lean out the motor and my o2's show rich.. I just might put the 4psi pulley on, take me a few minute to swap it off.. Umm but yea other then that.. I belive I should be good... I actually think one of the idler pulleys goin and makin noise when drivin and boostin, not sure why not all the time but iw as gonan change it last time because when I did spin it in my hand off the car it was pretty loud.. I get pulleys cheap as hell no need for me not to change them..

Thanks again guys.. Anyone know the MM or Inches for the belt for the 2.4(4psi?) pulley and the 2.2"(5.5psi?) pulley.. Cause really the belt does feel tight but i am bottoming the tentioner out basically, and maybe it just could be a WEE bit tighter.. Ill see how ti goes.. each day its been gettin beter so I should be ok..

Search...and all will be revealed: http://www.solaraguy.com/viewtopic.php? ... sc&start=0

As for the pump it's a Walbro 190 using 5 o-rings. You will need to modify the holder on the bottom in order for it to fit.
Not to be a prick but, if you search you will finds out exactly what is required.

by **20SoLaRa02** » Tue Oct 28, 2008 8:49 am

boost port is on the s/c right below the strut tower bar. people have problems with the fitting that goes there hitting the strut. some have put washers to raise the strut and others have cut notches in it. good luck with that.

as for injectors check this link out: http://www.solaraguy.com/viewtopic.php? ... sc&start=0

for belt size i believe people have been using Dayco Polycog Belt (5060880)
6PK2235

good luck,
Michael

Just outta curiousity.. I got 2 ports right below my STB... My left one didnt come with a nipple or anythign so I just plugged it off and hooked up the right side one to the actuator.... Is that the one seeing boost or is it the left one I plugged off?

So yea... New to the forum... Need some advise lol
