You guys should meet 1/2 way & race!!! Where's that, somewhere around the BC / Yukon border on highway 97?? No chatting, just drive till you meet, race, & drive home.

Installed 16v Master, booster and pedals the other day. Just need to bleed them now. BOV is shimmed and the stack is pumping lots of smoke now, very sexy. Hope to install the nitrous and have a WOT video posted very soon.
why do you have a BOV? they are a waste of time. if you dont have a good reason to have it on there, you should take it off. or do you have it there for a good reason?

he shimmed the BOV so it would not open, as a stop gap until he can get a blockoff plate for it.
and as far as the race goes, I would be down, but thats farther than I want to drive in a weekend(and I only have weekends now that school started)

well, I went out and bought the stiffest springs I could find.
they are 1.5" long, which is a little longer, but I think I can adjust the throttle lever position to make up for it.
I got a fish scale, which has a tape measure built in, which makes measuring pounds per inch very easy.
I measured the springs, and they are only 11lbs/inch.
they are very clearly MUCH stiffer than the stock governor spring, and I will just have to see what they do as far as max RPM.
the other thing I thought about is shortening them a little(cutting some coils off, and bending one back into a loop) to match the length of the stock spring, which would make them a little stiffer.
parts are still in the mail
but hopefully they will come today.

just received three of the four boxes of parts I ordered.
the only thing still on the way is a new timing belt for the G60 supercharger, which is not needed right away, so I am content to let USPS spend a few more days with it.

an interesting
article about electric superchargers
just get a big capacitor and bingo

fair enough. just thought i'd throw it out there as a viable alternative to all the bulkiness of traditional supercharging, not to mention the reliability issues...

some guy around town has a turbo saab that supposedly has one of those on it. he calls it twin charged. he keeps telling my brother he can beat him in a race. my brother has a corrado slc with a stage 2 vortech supercharger, a big valve head, and a 2.5" exhaust all the way out the back no cat. I loled

well, I went and replaced the rod and main bearings,(not something I want to do in the car EVER AGAIN) and the old ones did not look all that bad, some obvious wear, but not enough to warrant the noise we heard.
put it all back together with a new clutch, transmission shaft seal and pushrod seal, fired it up, and guess what; the noise is still there.
confident that it was not a bearing nock this time, we let it run for a while listening to the noise.
it is a kind of hollow sound, like you are hitting the oilpan or valve cover with a pall peen hammer.
it is inconsistent, happens more when warm, its RPM driven, and diminished when the motor is revved.
I talked to my dad(a longtime marine diesel mechanic) and he says that it sounds like an injection noise, like it is too far advanced and igniting on the upstroke, making a "knock" sound.
so we are going to do some more fiddling, retard the pump timing, loosen the injector lines one at a time to see if it is one injector in particular is making the noise etc...
unfortunately, however, it became obvious that it was too late in the evening to continue(schoolnight etc...) so I will be heading back out tomorrow to see if we can finish it.

My Dad has a golf gasser that does that knocking, only it gets quieter when warmed up.
We changed the rod bearings and hydro lifters and it still happens, we suspect wrist pin bushing(s)
Hope your's ain't that, try loosening the injector lines one at a time and see if it goes away.

I am going to bet it is a combination of really advanced timing(from the fact that this pump makes pressure much faster than the VW one) and my poorly balanced injectors.
I need to get them professionally rebuilt and pop tested, I think one of them is opening too soon, which is not too huge of an issue until timed way to advanced, and it makes the "knock" (even farther advanced than the others due to low opening pressure)
for the time being I will retard the timing, but when I get the chance(and the $$) I will send a set of injectors out to giles to make sure they are right.

if its not the timing check the wrist pin bearings.

figured it out, it was a bad injector!
loosened the #4 injector line and the knock stops! and the engine speed did not drop like it would if the injector was working right.
I stuck a spare injector in hoping(a vain hope I know) that it would work, but alas it too was stuck.
so I have rounded up four injectors to send to Giles for a rebuild and calibration.
the car will sit until I get the injectors back.
I feel good about it, I know for sure what it is, and it is not a big deal to replace them(less than an hour start to finish)

well, I think I am going to buy a set of reman injectors from autohausaz.com
they are $34 with an $11 core, and they can be in the mail today(hopefully to get them by this weekend)
