How To Drivetrain :: Operation Vacuum Gain System (VGS)
#151
I've tried to resist the me-too post, but can't.:smile:
I had the VGS added at the same time as the lightened crank pulley and JCW injectors. The GIAC server was down so I couldn't get that done on Saturday.
BIG difference. No bog, winds up quickly, tons more power, yo-yo gone.
I paid $18 for the install while the IC was off. That's a lotta improvement for $18.

You need a scanner....

Cleaned out the oily IC while I was at it.
I now have an SES light. Anybody else see this?
I have a UniChip. I'll remove it tomorrow when I have time.

Without the scanner, you're just flying blind....

As others mentioned, post up the code. Also, check for vacuum leaks at the interooler boots and at each vacuum line connection that you made.

Ditto
Everything is fine. If I didn't know it was there, I'd have no idea that the car wasn't stock. No codes, no trouble...... But I didn't have yo-yo before. I just couldn't understand why Mini routed the vacuum source the way they did. Seemed to me that it was ment to creat oscillations in the stock configuration.

a little off topic
Andy in the pic below is this a temp probe
for pre intercooler intake temp
if so how did you do that
did you have to cut the rubber and then seal it back up
i want to use the outside temp probe and measure the post intercooler temp
but wasnt sure how to get a good reading
and didnt want to cut holes in the ducts

I wouldn't recommend using the factory outside temp probe. Your charge temps get way hotter than ambient.

FWIW: I just converted my car with the Helix Turbokompressor kit on it. I was trying to improve low boost drivability. When running at maybe 5 to 20% throttle, with the boost between 0 and 5 pounds, the car was jerkier than a pulleyed car. I gave it a shot, with one slight modification which shall now be forever known as the Ericphix Gain System , and it made a remarkable difference in the low boost smoothness.

My current implementation of the EGS is to eat and drink a lot, and I tell you, I've seen some significant gains!

wow... simply no other word can best describe this small, but very affective mod. the new found smoothness is amazing and it feels theres extra power because of it. but andy, couldn't you just remove the nibble from the intake manifold and attached it to the tee and connect a smaller hose from the tee to the manifold with another nibble? this would lead to the same result, but without cutting the stock line right? well just trying to help and good job of figuring this out.

Cutting the stock line????

o wait, i was only looking at the diagram and i just assumed you cut the stock hose and insert the tee there. but anyways, its a very good mod... but one thing puzzles me. you know how the on-board computer tells the distance to empty... it usually reads 320 miles when i fill it up, but after the first fill up since i did the VGS its reading 375 miles... wow thats a huge gain for a simple mod.

Yep, no need to cut any of the stock lines, so the VGS can be completely removed. I haven't noticed a gain in mileage but also haven't noticed a loss. Since my commute is so short, my mileage tends to be a) bad and b) different between tanks, that was both stock and modded. I'm helping a friend install a VGS on his car so I'll take some more detailed pics along the way.
