just a few questions guys. I have a Vortech V-9 kit with aftercooler and I can't get a boost reading at all off of the gauge except for at WOT and about 5500rpms any other time it is showing Vacuum. Is the gauge line possibly hooked up in the wrong spot?? Also I ran it last night with et streets and only improved .02 in the 1/8th from my s <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> tock times. is it possible the SC is not working??? Possible belt slipping what gives here?? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Boost is dependant on rpm which is dependant on the belt drive to accessories or crank and pulley size.

You either have
a) Boost gauge hooked up wrong
b) Belt slippage or damaged blower
c) broken boost gauge

From experience, when my pump was not kicking on, the motor was starved and would not build RPMs... and only got a couple PSI of boost. I got hte pump connected correctly and VOILA! I had boost. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

On your items a) and c) , how does that account for only .02 ET improvement in the quarter? <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I'm simply trying to help the guy out.

One of the things he noted was no boost.
One of the things I said he should check is his fuel (based on experience, not theory).

If you have a problem with that, take it up with your psychologist. I'm just trying to help the guys with things he should check. Sheesh!

 

While it is true you will not see a whole lot of boost except at WOT, you should see a LOT more gain in the 8th.

Check your fueling situaion, too. Lack of fuel will result in low to no boost. What does your Fuel Pressure guage say?

 

It stays around 60lbs on the fuel pressure gauge. I think I was launching the same way as I was when the car was stock but I smoked the clutch on the last run trying to do better <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

The gauge seems to work fine it shows 18-20lbs vacuum at idle amd is pretty easy to get back to 0lbs but it is almost impossible to get it to show boost and then at most only 5lbs won what is supposed to be an 8-9lb kit can the belt be tightened on a Vortech kit? I'm really new to all of this. How can I tell if the SC is damaged also?

Sounds to me like the compressor bypass valve is hanging open.

and yes, fuel supply has ABSOLUTELY nothing to do with boost generation. We're gonna get people thinking if they don't have enough fuel it's ok cause it won't let them build boost.

Since I don't have enough knowledge about this to fix this I live fairly close to Atl. Ga where can I go for help? I have already spent an arm and a leg and as far as I am concerned got nothing to show for it. I guess I'm just still upset. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

 

im south of Atlanta....Jonesboro...call me and
i'll try to help you troubleshoot it. Jerry 770-231-6810

 

There is always Atlanta chassis dyno.

I would take a look to see if there is a line loose or if the blow off is opening wrong and check belt tension.

Candlebandit ur a GAFBA member right? I will maybe give u a call later when I can I posted on the boards there too.If u are I will be at the cookout next weekend. I'm out of town right now at a class. As for Atlanta Chassis Dyno, they did my install and I would trust them with any work I had. They did not install the gauges for me but the car is running fine and does not feel like it has a vacuum leak or anything. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I know it's producing power but it's really hard to get the gauge to show boost except at almost 6000rpms <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> and it shows around 5lbs give me more consistent readings and I will be happy <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Nope not a member <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Call me anytime..maybe your balancer is spinning on the crank....if you want to go dyno tune sometime..provided you have ls1edit....i know a great place we can go..a little drive but worth it!

 

Chad, I think it's important to note that you dyno'd over 400rwhp at ACD's dynoject with a totally bone stock motor and just the blower.

I would say the blower was working then <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Does it feel a LOT less powerful now? Could a hose possibly have popped off or come loose? With 400+rwhp on those street tires the car should feel very powerful.

On ET Streets how were you launching? What was your 60' time? Is your clutch slipping possibly?
