Slowsix's project 3pointh8

Take turbo off and check that the gasket is not blocking the flow?

[PaxtonShelby]

Will it run “well” without the turbo hooked up?

Gasket is fine.

Will it run “well” without the turbo hooked up?

I don't have any way to run it n/a unless I run open forward facing headers lol

So what’s the problem?

So what’s the problem?

Nothing like some flames pointed directly at my radiator. What could go wrong ! Lol

[Ares]

Nothing a turn down can't solve.

[SlowSix]

Well, after doing all kinds of diagnostic work.
Car is getting shipped back to the engine builder...

Verified wastegate, cold side piping, blow off valve. Re did cam synchronizer timing.
Even tried another turbo.
Compression test reads 120 on all cylinders, which engine builder agrees seems low.

Pretty bummed out. Hopefully this will get taken care of and I'll actually be able to drive the car before summer is over.

Hate to hear that. I was hoping it was something simple. Let us know what he finds.

I was hoping so too, and everyone kept telling me it was something stupid.

Compression test shows 120 ish on all 6 cylinders. Which being even is good, but low. Should be seeing 150-160 on a brand new motor, plus the fact that it won't spool my turbo.
Engine builder thinks it may be an issue with my cam.

[SlowSix]

Well. Update. Car has been at engine builder's shop for about it a week.
So far - a couple loose grounds.
And this -

Not sure how the hell that happened.
Welded the intercooler up and it makes boost now.
Attempting to tune it now, but he said the fuel pressure is being weird. Spikes to like 60 psi and holds it there.

[sutyak]

Well, that's certainly unexpected. Glad you got that figured out!

[somethingclever]

doesn't explain low compression test numbers though

[SlowSix]

Agreed.
We are having some other issues as well, but so far the car made 427 spinning on the Dyno at 13.5 lbs.
He is really busy and says he is not sure if he has time to fix a few things that should probably be fixed

[SlowSix]

Well, another update.

Intercooler blew another weld apart so we are officially scrapping it.
Ordered a treadstone 1235 intercooler that is 3.5" core. Almost ordered the 1245 that is 4.5" but probably overkill, and it is on backorder.

Also changing to a tial Q 50 mm blow off valve to replace my turbo XS RFL that is maybe only 30 mm.

Turbo is going to be pulled to see if the drain needs re routed or the seals are bad (again). He said the turbo smokes like crazy and is leaking.

[PaxtonShelby]

Good times. Hang in there - this happens to all of us...except on Overhaulin’.

[SlowSix]

Intercooler I ordered is on back order as well. Son of a...

Need more NA cubes. BBF swap

In the words of Bob "needs more RPM"
btw, bob do you have a treadstone on your car ? How is it and what size ?

[Martin0660]

Yes mine is Tredstone, best of the economic intercooler in my mind ....

cant remember part number and I think they changed their system anyway ... it’s a basic 3” core, 12” high, 28” core length, 3” in and out
