need help my sc14 has made my car slower

Hellllllllllo
Got a boost gauge? if not get one, then see if you are making any boost, if not check for belt slip, leaks.

Got boost?
Fix the tune

Actually I just noticed you live in queensland, no way in a fit you will be able to run 3lbs of boost on the stock VN timing up there

 

I could but it's much better that you invest the 70 bucks into a eprom burner if your going to live your life with a boosted commodore. Things will change, boost will go up, turbos will go on. It's better to be able to retune it as needed. Then I can just email you a little one bar tune to get you started so it runs how it is, no stress. I don't like stress

 

Ok find me in msn, am I findable?, hope so

 

yep performence loss.
crs quote no performance loss with the kit off.
the sad truth is that is propergander, compleatly untrue.
u must suck your air in through stationary turbines.
which will create a massive restriction.

and it will run slightly rich with the blower blocking up the intake when its turned off.

i discussed this topic a while ago.
i recon u lose 10% power with the blower off.

do u mean u arent goin as fast as u should be with the blower on?

first thing i would do is get a boost gauge.

basically with the blower off put your foot flat on the accelerator in 1st or 2nd, it should go strait to 0psi if the blower wasnt there. if the blower is and turned off it might go to -1 or -2psi, meaning it is definetly restricting the intake.
this is costing u horsepower.
but dont worry, u shouldnt really be going full throttle with the blower turned off, unless draging a 4banger.

now having said that(or typed it) the blower should register between 2 and 3? psi when you flatten your foot in first or second or so on. this really depends on your fuel system. i think another member on this forum got 4psi or even 5 from the stock pully. this was with a rising fuel pressure regulator.
but i am unsure about which 1 to get.

And greanfoam. where would i be able to get myself a eprom burner and is there a thread u can link to using 1? cheers.

and dont forget to take off your pcv hose and run it elsewhere.(airbox) so its not getting boost its getting vacuum.
and if u havent removed it take out your bellmouth thing.

 

noway would your piping be too big.
the bigger the piping is the less the restriction.

geez your car is slower with boost, wtf?
must be a fuel or tuning issue.
take out bellmouth first.
are you running premium? crs recomend premium
are you using a blow off valve?
are your sure the blower is turning on and locking up the pully compleatly?
is the belt slipping?

im using the stock sc14 outlet pipe which is 2inchx 2 1/2 going into a silicon
2inch-3inch adapter then a 3inch pipe with a metal show off valve welded on
going into a 3inch right angle silicon adapter

my inlet pipe is a pod than 3inch pipe going to a 2inch-3inch right angle adapter which is a big restriction

b4 wasting time on burner make sure leads on on right way round and plugs are good and vacuum line is corect cause adding one of these chargers do make power so if yours has gone down you have a prob somewhere and new chip wont do jackshit

 

the one that goes to car from bov
when i did mine i origanlly had it to the rong spot till someone told me
ops me silly

 

these blowers on stock motors do lean out but your saying it runs like **** and mine doesnt and heaps others dont so its not a tuning thing its a bad setup somewhere

 

He's had it pinging at 4600 rpm, so it must the retarding the spark heaps and to do that it must also be running very very lean, why it it running leaner than other peoples? maybe there's another problem with the fuel system, I dunno. I just hope I got the tune right

 

heheeeh see told ya something was rong
4psi is good most wont even make it to 3psi
