Test drove the Elco tonight. Whew!! 10PSI instantly. It does not seem like the same motor. The tq really seemed to overwhelm the trans too. Had to retune the injectors for the boost and found them nearly maxed out. But the engine is happy and can't wait till Fri eve. Tires blow off easily! Makes 1st gear feel useless. Tom

EFI-DIY,
Before reading your comment, had allready lowered the wastegate setting to a more moderate boost. Upon looking at the data logs, the boost was approaching 15 PSI!
Got to the track, long story, short one is , no new bests, yet. Something happened to the engine. I believe one or more of the intake dividers may have moved. Going to open up the intake and take a peek. Could not get boost to come up like the night before. Every trip down the track was low 14's but just could not muster up the boost. Even tightening up the WG provided no more boost. Keep you guy's posted.
Here is a funny one for you. When going thru tech, they have you open the hood. They look for a catch can for anti freeze and any other hokey stuff that may cause liquid on the track. The young (25 ish) tech guy ask's what kind of motor is that? He had never seen one.

If the devider/s moved & caused a restriction,that would not limit your boost,actually it might actully show an increase in boost.
Thats part of the reason why my Syclone makes so much boost, the heads are restrictive.
When switching to better flowing heads,your boost will drop & normally you would make more power w/less boost pressure.
So when you have opened up your head as you did,w/out changing anything else,you might have lost some boost pressure.
Tlowe Quote: "Even tightening up the WG provided no more boost"
When just tightning or adjusting your wastegate spring, that will normally only adjust your base boost pressure.
"CarCraft turbo expert/guru. Get this Elky to run like it should.
My 3600 Truck (no driver) is on the verge of 11's,does not need a diet,just more boost! It's a street car w/A/C fully loaded.
Tlowe,don't you have an electronic boost controller?

Hank,
Not quite sure how to take your comments.
Your cyclone is / was a factory designed turbo setup. Everything about the fuel/ spark/ engine was also designed for it to run fast with a turbo and EFI.
I am working with a engine never designed for:
EFI
Turbo
Hot rodding in general
No one's footsteps to follow either.
You also know that I do not use a electronic boost controller, what's up with the bashing? Maybe I am taking your comments way out of context.
My setup has a manually adjusted waste gate. I am confident that the problem will be found and solved, and then other people may be able to learn from what I do.
Got to go back out and get some work done.

I think you are taking my coments out of context.
"Get this Elky to run like it should".
Those are words of encouragment,& I guess pushy.
I do not know your complete set-up,that is why I asked.
I do not recall you ever stating the only way you control boost by just the wastegate spring & adjusting it.. I must have missed that.
I would suggest to purchase an electronic boost controller since I know now you do not have one.
The Syclones are not factory GM designed vehicles,a company named Pas,(not in business any longer) modified/outfitted standard,Sonoma trucks.The turbo is a mitsubishi Jap turbo.Pas ordered them.
My Syclone used to run 14's,if you call that fast.?
The Syclone engine is just an engine as any other engine.
Almost any engine can be made to EFI & turbo.
Mike Kirby has been fuel injecting inline 6 siamesed port heads for years,w/great success w/no intake port deviders.
Only thing different in the Syclone longblock over a 1991 Chevy Astro van is lower compression pistons,that's it.Which BTW,was never designed to turbo either.
Hope you find out your problems w/boost.
Your Elky shuld run a lot better than it does,not sure if you realize that.
Not putting you down,your Elky has or should have a lot more potential.
MBHD

Ok, I'm chilled. I have a feeling one or more of the plates have turned / bent and are covering up/ restricting intake flow. While tuning on Thurs eve, the engine had a few hiccups ( backfires) at part throttle and those in the past have caused blown intake gaskets. Imagine the pressure in the intake.
I drove it yest afternoon to pick up the daughter from work and at low throttles it runs good, it like a cork has been thrown in it for boost. Tom

Well, worked on the Elco this afternoon. Pulled the intake, All dividers are in the exact same place I put them. That makes me feel better. Also my special intake gaskets with very little contact area are still holding up fine.
Checked compression and have 150 on all cylinders. So no problems found!
Put it back together and fired it up, it is running better again!
Seems while looking it all over, the crap rebuilt dist is a two piece design. The long part of the housing is pressed onto the bottom of dist base. There is movement at this location, none in the spinning direction but some in the fore/ aft and to/ from engine. Nothing makes contact inside dist when this happens. I figure the module was getting a BAD ground thru this moving junction. So I tied another ground thru the inside of dist, drilled a hole down and attached ground to lower dist housing. Engine seems to be much happier when driving and can now hit the wanted 10 PSI boost.
It always boils down to the small things, no fire, no BOOST! It did not even miss, just seemed weak.
Hank,
Not understanding the boost controller giving more boost quicker. The WG stays closed until the desired boost is achieved.
Maybe the electronic ones can open faster and therefor allow the gate to stay closed a moment longer. I am happy with my boost control, it seems to work very well.

?????? if the waste gate is closed and not opening until boost level is achieved how does a controller help with spool time???
In my book that is a function of exhaust gas mass, Delta P across the turbine, A/R ratio on the housing...
I can see it helping to cut the boost back during launch to stop blowing the tires off.. but faster spool... explain please. [/quote]
If you could see your wastegate while boosting,you would see the wastegate opening a little before it actually will open up more to the setting/spring pressure it is set to.
So, say you have a 10 psi wastegate spring in your wastegate.
You would think the wastegate will stay closed just up to 10 psi,well ,it does not,it will be creeping open before 10 psi is reached.
With an electronic boost controller,it will hold the wastegate completely close until the desired setting is reached.
Therefore,your turbo will spool faster up to the desired setting,because the wastegate is completly closed(forcing all exhaust gasses through the turbine housing & not bypassing the turbine wheel) & not partially creeping open.
Not sure if I explained that correct?

I am ready to try it again. Just got back from a 2 week vaca. Test and tunes are on Friday eves and my Fri's are all booked up with something else.
Been driving it alot and having a ball. Wife is quicker to put her seatbelt on too. It is a noticible difference in running. The new dividers allowed a much leaner run and the fuel mileage is up. So is the throttle response.
Power has to be higher than it was a few years ago.
So when are all your parts going to come together for the 9 second street 69 camaro?

Here, you can see how an electronic boost controller works.
There are 4 videos,this is the first

Another thing about running an electronic boost controller is that it it will cause your turbo to spool up faster,something to consider.

Have not had a chance to work on that drag elco. Been too busy with setting up the 292 and 250 engines to dyno. Along with building heads, making lumps, Inliner conventions (FUN STUFF), building rears and family stuff, work and vacations. My minutes are almost all accounted for.
Got some plans to get started on it again, have collected a few parts.
Hope it will run 15's, that way I won't be disapointed. Not sure on which motor. It will also be street legal (so it can be tested more).

My intake was machined to accept injector bungs, the fuel rail is from Ross fuel ijection ( it is a dash 6), the throttle body is a stock 5.3 Chevy truck V8 part.
My control computer is a Holley Commander 950. The distributor is from a 81 chevy truck with Calif emmisions ( electronic timing control).
This system was pieced together by me.
The turbo manifold is available from DEI, the company that sells heat wrap products. Tom
