Title: gillis vs. turbo xs.
Post by: turboranger91 on August 10, 2007, 09:54:14 AM
i figured out why i was never able to boost beyond 15psi...

i swapped the gillis valve out for my turbo xs bcv, and i was finally able to go past 15psi. with the current timing, it won't detonate until about 19-20 psi. i set it at 18. it's got a bit more pull in the mid range but that's about it. i need to get the oil leak and the coolant leak fixed, then find some higher octane fuel so i can see what 22 psi will do at the track. Twisted Evil

moral of the story:

gillis valve ftl... txs valve ftw.

You had the low-boost spring. Gillis also makes a high-boost spring. Guess which one I have. NO problemshiznitting 25+ psi ;)

ah, i wasn't aware there were two springs for it.  oh well.  i had the turbo xs part just laying around and figured i'd give it a try.  it's easier to use too... you don't need any tools.

i'm sorry.  honestly, go to grainger or any hardware store that sells air compressors.  buy a pressure control valve.  i ran one of those on my truck for about 3 years with no problems.  fully adjustable from 0-100psi.:D

it's cheaper then dirt too.  i think i paid $6.

I can hit 18 all day on my Gillis. They're not idiot proof, though. I can attest to that. :P

Just build a ball and spring valve for like $3 like I did.

ive seen 20psi with my low boost spring'd gillis. it wasnt the spring that was the problem...

maybe this:

Boost is too low.
     

If no matter how far you screw in the cap and the boost stays at the factory level, there's a chance the ball is not sealing properly inside the valve due to debris or oil contamination. Unscrew the cap and clean inside the valve.  Use a solvent that does not leave behind any oily residue. Brake cleaner or isopropyl (rubbing) alcohol works fine. Do NOT use WD40, or carb cleaner both will leave a sticky residue.

If the wastegate is shot, a boost controller will make no difference.
