Ok guys here's the deal. 60 trim big shaft turbo with a 70 a/r exhaust side. Ebay turbo/ garret rebuild kit.
These aren't even full spool numbers just plain...spooling

1st- 6,500
2nd- 5,500
3rd- 5,000
4th- 5,000

No exhaust leaks going to the turbo anymore everything is good and tight. No vacuum leaks at intake manifold. Tested that out with some carb cleaner. I should run a boost tester on the rest of the charge piping to make sure but I'm almost positive thats not the case.

As far as tuning goes. With how late I am spooling power enrichment tables are absolutely zeroed just to keep me off of 9.0 afr. Pulse width shortened a ton. Volumetric efficiency is the only thing we're working with now. And it's still going mad rich at 4 grand. Turbo almost can't spool overtop of how rich it goes for like 500 rpms.

Timing is 9 degrees till the turbo starts to spool then climbs to 15-16 with no knock at all

The 80's are working 31% duty cycle at 7000 rpms was the highest we saw.

I need ideas here. Things I should try? I'm running out of ideas. It wouldn't be over oiling the turbo would it? My restrictor snapped off when I was bolting this together so it's just straight feed line. But it's not ball bearing so that shouldn't matter correct?

Is the turbo just plain too big? Another member on here ran it for a while with no issues and said it spooled faster than his 56 trim did. It has to be something I'm missing. When the car does finally spool in 2nd and 3rd it pulls good, but it's using absolutely no fuel at all. I just don't get it. 11.2 is where I end at

Suggestions pleaseee

 

"Timing is 9 degrees till the turbo starts to spool then climbs to 15-16 with no knock at all"

this doesnt sound right. even without boost your timing should be advancing anywhere from 25-30 degrees btdc. if your timing is staying at 9 degrees until boost and 15-16 degrees under boost your timing is retarded way to much which is going to cause poor ignition, lack of power (the catalytic convertor will be producing high amounts of sulfur and you will smell rotten eggs) this will cause the turbo not to spool up because the exhaust flow is limited because of incomplete combustion. are you using hp tuners? how did the timing tables get like that?

 

last time mine didnt spool it was a HUGE leak. cuz the IM had cracked

 

My timing used to be that high. But we pulled it down I was listening to hungrychip he told me the exact opposite. I am on open downpipe and I never run a cat anyways. I was under the impression that less timing and little more fuel will create the heat to spool it. Yes hp tuners, we set it up that way. And after I did it we gained some spool time

Yeah man no leaks... Sprayed all around it with carb cleaner and rpm's never moved.

 

low timing more fuel speeds up spool time you have a leak somewhere

 

Do you think it's exhaust related or charge piping?

 

If you have an exhaust leak, I don't think you method of checking for leaks would work....

 

It could be the downpipe, turbo elbow.... you could have a crack in your intercooler, or a busted coupler...

I've seen them all... you have to go over the car with a fine tooth comb

 

I do have a big leak off the elbow going to the downpipe. The 5 bolt flange. It needs fixed but I didn't think that would have anything to do with spool time. Please tell me I'm wrong haha

 

Uh, yeah it's letting out compressed air man... also not allowing a full seal on the turbo.

 

What are you running for a wastegate? Have you swapped it out for another. Sounds to me like you could be missing an obvious wastegate problem.

 

put your timing back to stock. at 9 degrees timing your engine isnt making power. your max timing advance needs to be at peek torque. once peek torque is reached then you can retard the timing. you shouldnt have to adjust timing on low boost applications. for ex: if your running 20 psi boost then you should only have to retard the timing 2-3 degrees for a total timing advance of 22-23 degrees btdc. if your running low boost 8 psi or less you shouldnt even have to worry about timing changes. i have never heard of a car running at a set timing advance. as the engine rpm goes up the timing has to advance as it needs more time in order for combustion to happen at 15 degrees after top dead center.

 

Ok i'll get that fixed and let you know what happens.

The wastegate is working perfect man. I thought it was that for so long but after alot of troubleshooting the thing it works fine. Holds 17 pounds perfect just like I need

That is stock timing for my car? I'm not turning it back up to 25 degrees to be honest with you that's the least of my problems. It spooled about the same at 25 as it does now. It runs better now it's staying there for right now

 

did you try that timing map i sent you? did you just kinda try and map it out off of what i explained in the other thread? my bad i know i lagged on sending you the tune i just sent it last night at like 3am lol

try that one its for my turbo, but i have another one i have been working on for how i think yours would spool, i want you to try that one too. but try the first and log and send!


the exh leak, is it the one in the pics in other thread where you cant get to the bolt? that was a huge leak from what i saw but it was post turbo so how much its gonna matter is yet to be determined. but def fix it asap, use a allen head there instead of that 6 point 3/8 or what ever.

it will come around bro, your fuel sounds like its a mess also honestly. but thats something that i dont have a map for.... if you had 60's i could hook you up with a decent place to start with but that would be going backwards at this point.

 

if u have 80s let me know terry I do too maybe i can help u out or something i have my base tune still i beleive

 

ok. good luck.

 

Haha dude where did you send it to? terry11@ptd.net?
I didn't get the timing map or the fueling
Maybe try and resend them. I just set the timing as close as I could to how you described it. Seems to be good I have no knock.

Yeah thats what I was thinking since it's after the turbo it shouldn't matter... but I could be wrong. I don't see how it's different than someone running an open downpipe. You can send the one for 60's if you want I can put try it on the 80's and work off it it.

That would be awesome man. I would try anything right now. A base tune is all im looking for

 

yep drbalt just did a lsj turbo swap and got a copy from me. and used it and he is in love

 

are you using an extrenal wastegate? if so, check the sealing ring in between the wastegate plunger and mounting flange. a lot of people forget to install it. without it, exhaust will leak past the wastegate plunger causing a lot of lag.

 

Yep it's in! The wastegate is solid.

haha alright sounds good man. Hook me up bro!

 

pm me about it

 

yeah i copied and pasted from your pm. hmmm i'll send it like 3 times right now. wierd you should of got it.

 

did you check your

 

Yeah man I got your tables! We're gonna tune more tomorrow. I have a log to send you tomorrow so you can check out the fueling and timing
