more supercharger talk

[truckinwagen]

well, I got the timing sorted(kinda, I need to advance it a tiny bit, but the injection lines are in the way)
it starts a little hard, but much better.
no longer do I have to crank it over and over again, now I cycle the glowplugs, put my foot in it and crank it for 5-10 seconds and it starts!

I need to keep my foot in it a bit for another ten seconds to keep it from dying again, but thats no problem really.

it drives about the same, no smoke(even at full pedal) but the EGT's are up(not a surprise really) to 250@idle, 500@cruise(55MPH) and about 800 max/WOT

I took it for a cruise and noticed that the water temp comes up FAST, like needle moving before I am out of the neighborhood, and up to 180* within a mile and a half.
but the temps are stable at 180* once they get there, so I am not too worried.

cruised down to schmucks,(on the highway for a bit) and got some belt dressing.
I sprayed it on the serp belt, and guess what? thats right the squeal is gone!

now that injection rattle is down a bit(from retarding the timing) and the belt squeal is gone(as well as the slip at high RPM) I can hear the heavenly sounds the charger is making!

it is clearest during de-acceleration in gear, when the motor is still spinning fast, but the injection and exhaust noise is low.

it is a very unique sound, and I like it! not at all like the shrill whine of an eaton, much lower and more throaty.

I have the biggest grin, now I can drive it and not worry about it firing back up when I want to go home!

add more fuel please

[truckinwagen]

will do, the plan is to install one of the stiffer springs that were so kindly sent to me and see what they will do for fueling.

also, anyone have a spare block off plate for the block(where the diaphragm vacuum pump returns to)?

I went to a vane style pump, but the block "breather" is pushing out LOTS of oil(as it does not have the baffle that the valve cover does)

I have gone through a quart of oil already in less than 100 miles.

any motor with a vane pump on it from the factory should have the proper blockoff plate.

anyone want to be kind and send me one from the junk block they have sitting in their barn?

-Owen

[RabbitJockey]

i think i have one some where, if i can find it soon enough i'll send it to you.  but it will be a couple days till i get to my garage and i have no idea where it is at all.  honestly if i were you i would add a hose and T that vent in to the valve cover vent.  On my old rabbit it would blow all kinds of oil out of the breather (and cause run away problems)  until i added the older vent plate and Teed it into the rest of the breather system, then i never ever had problem with run aways or oil consumption.

[truckinwagen]

I wouldn't mind running it(more venting is better) but I dont like ho much oil is in the gasses coming out.

the valve cover has a baffle to keep the oil vapor in the motor, but the block breather does not, so any oil that the crank slings just heads out.

[truckinwagen]

well, I got it running! and well!

I swapped out the old governor spring


for a new one


here they are side by side


as you can see here the springs ends were looped too far, keeping me from hooking the lever on it


so I had to trim them a bit, like this



it is sooooo much more fun to drive now!

it starts faster, idles better, and the throttle is less twitchy!

it makes unholy amounts of smoke at full throttle(way too much, I will dial it back a bit) and burns the tires off right through fourth gear(roads are still crappy, but still)
and Holy Understeer Batman! its a handful to drive!


time for more boost!
its making about 10PSI max right now(about 5-8PSI under most driving conditions) so it is officially time for a 52mm pulley(and 20-ish PSI)

-Owen

[truckinwagen]

oh, and it was this spring


thanks andrew!
I plan on trying the other two out this weekend as well to see how they compare.

-Owen

[truckinwagen]

I took it to 4500RPM, but power trailed off a bit there so I shifted.

I think it will easily get to 5000+, but I will check better this weekend when I can stretch its legs on the highway.

-Owen

[truckinwagen]

ok, so to turn 5500RPM( a good target for max I think) the car would be going 50MPH in second.

so next time I go out I will stick it in second and see how fast it will really go(I chickened out at 40 in second today)

that should give me the info I need to plug into the trans calculator and figure out max rpm.

either way, it makes sooo much power below 4000RPM, that I dont think I will ever really take it above that, except to go really stupid fast in a straight line (5500RPM in fifth is like 120MPH.)

I will report back!

-Owen

[truckinwagen]

I have decided on a name for my GTI(or at least the monster under the hood)

the encyclopedia britannica defines "Ifrit" as an infernal creature of smoke from arabic mythology.

right now I cant think of a more fitting title, so as of this evening the diesel G60 is Ifrit.

[Turbinepowered]

Any idea why it's shoving so much gas out the vents? At least, that's how I'm reading your posts about the venting issues?

[RabbitJockey]

new driving movies

when is the big turbo going on?

[truckinwagen]

well, the turbo will wait until I have more than $200 to my name.

the spring has really changed the motor from a decent putter to a real beast!
I cannot thank you enough for letting me try it out, it really is just the ticket.

as for the vent on the block, its not that it is pushing too much blowby out(there is a good bit as the rings are new and have not seated all the way) but that the gasses coming out are heavily laden with oil.

the blowby coming out the valve cover(that goes through the baffles) is pretty clean, you can put your hand by the vent and it will stay clean, whereas if you put your hand by the block breather it will get covered in oil in short order.

ok, this is great, I feel awesome!

I went out this morning to a cold car(no block heater or space heater under the hood last night) I wanted to see how it would do on a real cold start now that I have the timing etc. sorted.

I gave it 15 seconds of glow plug, mashed the throttle, and it fired!
lots of black smoke came out from the seams around the hood(still need to fix the leak in my downpipe) and I had to keep my foot in it a bit, but no struggling to get it running!

this is the first time that I have not had to beat on my diesel on a cold winter morning to get it up and running!

that, and the charger just sounds so good!
I probably look like an idiot when I am driving, because I have a huge grin even just sitting in traffic!

58mm pulley has been purchased!

now all I need to do is figure out my intercooler/water sprayer.

need to find a new water/meth nozzle as I misplaced mine
