0-60 confusion - richclan - 06-27-2011
well i did my allotted reading on mild performance gains and nothing worked to increase my cars performance.
i did clean out a plugged banjo intake fitting to the limiter valve.
limiter valve is clear and holds pressure
alda holds vacuum and pressure
alda was already adjusted 1/2 turn from full adjustment. so i turned set screw the 1/2 turn ccw
stock time 20-21 sec
times below reflect all mods added together and no power braking
ingen intake filter 19-20 sec
removed alda 22-23 sec noticeable power loss
plugged egr vac line 22-23 sec
put it all back to stock and changed secondary fuel filter for yucks
and did a 20 sec
these times are sort of accurate. im pulling out from a side street each time so maybe the car is slightly faster. also im looking at my gps driving and doing the stopwatch on my phone lol
1985 300D turbo 58K miles with no trans slippage
RE: 0-60 confusion - led-panzer - 06-27-2011
Alda removal should have helped, did you plug the line going to the manifold? Bypass the overboost protection on the firewall? Make sure the shaft under the alda has its spring?
Is this the California version with the trap oxidizer? If you have the trap ox don't expect any miracles, I had to ask my car politely to get to get going before I removed it.
RE: 0-60 confusion - richclan - 06-27-2011
did you plug the line going to the manifold?
no it has to go to the trans shift controller, its blue if that helps
Bypass the overboost protection on the firewall?
yes and it was removed along with the alda
Make sure the shaft under the alda has its spring?
yes i pushed it down and it went back up easily
Is this the California version with the trap oxidizer?
no
also my car doesnt put out any smoke on full throttle

Ah, I forgot about that one, I just ran the line directly from the manifold to the blue flying saucer.
You have a boost gauge? I guess it could be the pump, I just have a hard time believing it would be out of adjustment after only 58,000 miles. Maybe the timing is off
RE: 0-60 confusion - richclan - 06-27-2011
no i dont have a boost gauge but i do have a diag tool for vacuum and pressure i wonder if i could use that?
how much pressure would it have to read?
RE: 0-60 confusion - led-panzer - 06-27-2011
You want boost at 10-15 psi. Some people are boost nazis and freak out the minute they get over the stock 9 but to their limited credit anything over 15psi doesn't gain you anything with a stock pump.
RE: 0-60 confusion - richclan - 06-27-2011
ok i'll try to test it
where do i read the pressure?
i assume ill need a t-fitting and be driving it to get a proper reading
RE: 0-60 confusion - led-panzer - 06-27-2011
Yes you will need to be driving, revving in park won't be accurate. Tee into the alda line it works great. This is on regular diesel right? No veggie oil or anything like that?
RE: 0-60 confusion - richclan - 06-27-2011
lol yes i've been running a veggie / diesel blend for 4 years
RE: 0-60 confusion - led-panzer - 06-27-2011
Lol that changes everything. Not only will veg make it a dog, it could have killed the pump. I don't know how you filter and dewater or what system you have but, as someone else put it, its like taking water from a dirty pond and filtering it to drink, get it right and your good but get it wrong and your screwed. That being said I in no way meant to be condescending about the way you do it, I have a pretty neutral stance on veg oil - its not something I would do to my own car but I have been involved in the process with others and I've seen when/how/why it can go wrong.
Still check the boost though.
RE: 0-60 confusion - richclan - 06-27-2011
im getting a solid 9 psi
the car runs strong no issues with it
RE: 0-60 confusion - led-panzer - 06-27-2011
Maybe try cetane additive to make up for the veg. At this point I don't know what else it would be. Good luck
RE: 0-60 confusion - richclan - 06-27-2011
i adjusted the wastegate turned it in 4 turns 1/2 turn at a time i didnt want to go any farther in just in case.
got the boost up to 10-11 psi the test gauge was maxed at
10 psi so i rigged a tire gauge which reads 0-60 psi and it too read 10-11 psi
just to make sure the alda wasnt leakin i bypassed it. reading didnt change
RE: 0-60 confusion - Captain America - 06-28-2011
Good thing forced induction isnt here!
RE: 0-60 confusion - richclan - 06-28-2011
any more ideas?
RE: 0-60 confusion - DeliveryValve - 06-28-2011
Wow. 58K miles on the clock and running veggie. Yikes!
Did it always had that time? I would check on linkage adjustment, make sure there is no slop and the hitting stop on full acceleration. Also lubing the linkage joints help.
.
RE: 0-60 confusion - randomdude - 06-28-2011
any pics of what the linkage looks like when hitting the stop? i dont know where it should be.
RE: 0-60 confusion - yankneck696 - 06-29-2011
I would mist the engine with water to remoce buildup & coking in the combustion chamber. You might be getting blowby from stuck rings, too. Veggie has a tendency for coking, that's why a water injection system is suggested.
Ed
RE: 0-60 confusion - richclan - 06-29-2011

sounds like a good thing where would i spray the water, in the turbo?
fyi the egr wasnt that dirty nor was the intake as far as i could see in it.
i run a blend of veggie, 30% of my fuel is diesel. i think its the best of both worlds
Did it always had that time? I would check on linkage adjustment, make sure there is no slop and the hitting stop on full acceleration.
never worried/tested it till i started driving it on the highways. i wanted more entrance ramp speed.
i did adjust linkage but it wasnt off but maybe 1-2 /32's
i am going to disable the ARV valve also

See attachments for FSM accelerator linkage adjustment.

RE: 0-60 confusion - richclan - 06-29-2011
ill check it again
now im getting a 17 sec 0-60 time
most posts say 13 sec is normal
so what is a good time to shoot for????
RE: 0-60 confusion - randomdude - 06-29-2011
as fast as possible lol.
RE: 0-60 confusion - led-panzer - 06-29-2011
Yankneck had a great point there with the water injection
RE: 0-60 confusion - randomdude - 06-29-2011
^true true. would be especially good for a veg car.
and thanks a million DV
RE: 0-60 confusion - winmutt - 07-01-2011
If you are not getting black smoke your not getting enough fuel. Check the overflow valve spring? I've got a 11s 0-60 on b100. Need to do the pull in a straight line, sounds like your turning onto a street?
RE: 0-60 confusion - randomdude - 07-01-2011
^where is that valve spring? and how do you check it? i NEVER get smoke (alda full out helped give a lil pep), and car's a bit dogy.

can you post a link on a diy overflow valve spring adjustment
i put a new air filter on and ran a can of diesel purge through it.
it feels much better on normal driving.
i am also going to do a valve adj. next week

I think he meant they Bypass Valve on the IP.
http://www.superturbodiesel.com/std/showthread.php?pid=31323
Adjusting it should help with performance if the spring is flattened.
.
RE: 0-60 confusion - winmutt - 07-02-2011
Stretch it to 27mm.
RE: 0-60 confusion - randomdude - 07-02-2011
ah thanks for the link, i will do that tomorrow!
RE: 0-60 confusion - richclan - 07-06-2011
stretched spring to 27mm and now visible smoke when warm revving it up in the driveway. i dont see it when driving though. im sure at night it will be noticeable in the following cars headlights.
i'll adj. valves this weekend then test it.
RE: 0-60 confusion - richclan - 07-07-2011
well this doesnt make any sense
0-60 now 18 to 19 sec this is straight line and power braking engine to 2K rpm
winmutt you get there in 11 sec????
what am i missing
RE: 0-60 confusion - led-panzer - 07-07-2011
Winmutt has done mods to his pump - rack limiter removed, torque control, ect. Among other things, not a good comparison

i cant afford to do that im sure but i want to get back to at least stock. 14 sec is stock i think from what ive read.
RE: 0-60 confusion - led-panzer - 07-07-2011
I'm sure you could afford it, its free lol. I think the reason yours is slower is just from the vegetable oil, all the vehicles I have ridden in using veg were dogs.

lol what i meant was messing it up as in breaking it.
ill run it on straight diesel next run
i just noticed that the ip has been marked as if it was adjusted by the PO.
RE: 0-60 confusion - winmutt - 07-07-2011
Certainly check IP timing and use diesel as a valid comparison. 18s is not completely out of bounds for biodiesel, you lose a considerable amount of bang for your buck on it.
RE: 0-60 confusion - richclan - 07-09-2011
every valve was too tight. after getting them in spec i started it and it sounds totally different.
with just the u tube on it growls and i cant hear the spool up like before.
i now hear the solid lifters
like my solid lifter chev V-8.with air cleaner on its still noticeably louder and i dont feel any more power.
it also still has the hot idle shake
ill do a timed run to 60 later tonight.
im just wondering if this is the way 300d's are supposed to sound.

They must have had other problems too then.
RE: 0-60 confusion - yankneck696 - 07-10-2011
If you are to continue to use WVO, put a water injection system on the car. It will eventually net you better performance due to cleaninf the rings, injector tips & prechambers. You can also add some methanol ( or just use windshield washer fluid ) & gain a bit. It will also make the engine last longer due to less blowby & other things.

I'm not slamming wvo, but anyone who runs it straight will tell you the car is not as fast. Not because its "ruining your engine" but because it doesn't have as much energy as diesel.

thats an interesting idea to clean out the engine. can you list any posts about it????
RE: 0-60 confusion - yankneck696 - 07-10-2011
look up water meth injection. It gets activated by a Hobbs switch (at a certain PSI of boost) & should DEFINITELY have check valve/antisiphon valve to prevent leakage & hydrolocking the engine. Also, the pressure of the water pump needs to be enough to atomize the water into a fine mist. Best bet is to have a multiport system, due to the flow characteristics of the intake manifold. It was not designed to flow a liquid/air mixture.

Yes but in my personal opinion and experiance, it dosnt slow down the car by much..hardly noticeable.
RE: 0-60 confusion - yankneck696 - 07-11-2011
Fuels
Due to the excellent atomization, Babington burners will burn many heavy and waste oils such as:
diesel (~140,000 BTU/gallon)
biodiesel (~130,000 BTU/gallon)
kerosene (~140,000 BTU/gallon)
waste transmission / motor oil (~150,000 BTU/gallon)
waste vegetable oil (WVO) (~130,000 BTU/gallon)
from http://www.aipengineering.com/babington/Babington_Oil_Burner_HOWTO.html
Not a definitive source, but I would gather that with the right injectors, heating, timing & other stuff, no water injection would be "nessecary". When many people do WVO, there are alot of things missed in the setup.

RE: 0-60 confusion - dieselboy - 07-11-2011
My car was a little slower on vegi but it didn't make a 8 sec 0-60 difference.
RE: 0-60 confusion - led-panzer - 07-11-2011
You've been running it for 4 years like him then?

(07-11-2011, 11:30 AM)led-panzer You've been running it for 4 years like him then?
this car has always been this slow. it hasnt deteriorated over the 4 years. i rarely drive it.
my 240 has been the guinea pig for the wvo and i havent seen any performance difference/problems in fuels in that car
but now that the 240 is gone ill be driving the 300 more.
RE: 0-60 confusion - yankneck696 - 07-11-2011
Could be timing chain stretch, diff gear ratio, timing, adjustments that were already made, tire height, brakes dragging, trans slippage... If it's always been slow & there are marks on the IP, you may need to adjust. Also check boost...
