What brand of Wastegate ? I had VS ones dual 44mm and they did leak switched to a Precision 66 and it fixed my issue . I’m in the same boat SBE SBF with a 91mm GT55 with a PTC18/0 and I’m at 11.5lbs in 4 seconds. I’d confirm the compatibility of your input shaft with the pump you have that could be causing a problem with exhausting fluid out of the converter, also are you logging converter charge pressure? With mine on a th400 and the dump open I’m single digit pressure. You’d think with a 21/35 it would spool with out a dump with zero issues. Also I know you mentioned timing I’m at 42 degrees until 8lbs then it drops to 10 degrees up to the 4800 revlimit and makes 11.5. Good luck I hope you get this figured out I’m rooting for you.
If it has a flex joint on exhaust I’d check that, see if it’s collapsed. If it’s Holley I’d try deselecting all advanced tables just do a spark high limiter.
@@OverydeMotorsports Clearly "Looking it over", visual inspection of the "Hot side" from exhaust manifold through to the turbocharger exhaust input along with the "cold side"output has not located the boost issue => Thus, obviously via proper process, methods the means of checking are certainly insufficient.

Since You are not able to properly perform a "pressure test" nor would it easily or necessarily determine the precise location of the the leak(s), thus the most common, useful, helpful means for testing is the "smoke test" method.

I was going to ask this as well and wondered if you tried advancing the timing slightly to help with low end torque to help with the spool. I'm also assuming the chain isn't overly stretched?
@OverydeMotorsports right but if the deck height is different if could change what pushrod length is needed for preload.. though that obviously wouldn't get worse over time.
@OverydeMotorsports this would make sense, cause haven't you also had issues with it randomly making more or less boost and being inconsistent, would go inline with wastegate
While Ive personally had good luck with all my VS turbos......i would be really suspect of that turbo.... Get a Forced Inductions unit and dont look back!
Might go twins for next year! I would like to see what is up with this deal tho just to make sure I don’t start off on the wrong foot with a spendy engine
Yeah I get it! Hopefully you can get it sorted out. I usually stand up by the starting line at CATC and waiting for that thing to get up on the chip gives me anxiety 😂
@OverydeMotorsports I don't doubt it haha....I changed my bump settings one time and fat fingered the wrong duty cycle and the car would hardly move. I was on the brake for 7.5 seconds, but it felt like 7.5 minutes 🤣

It ended up being the stator bushing in the trans went bad. Letting way to much charge pressure through
@@OverydeMotorsports glad you figured it out..
What are the specs on the turbo? Exh wheel size, turbine size. Whats the cubic inch? Also cam specs.
Do you have a flex section in the crossover?
No sir
If it has a flex joint on exhaust I’d check that, see if it’s collapsed. If it’s Holley I’d try deselecting all advanced tables just do a spark high limiter.
Will do! No flex pipe in this one
Are sure it’s not a hot side leak?
Positive. I’ve looked it over a million times haha

What timing set do you have?
If it's adjustable are you sure you lined up the right dots?
It’s the summit Racing one. I degreed it with a wheel.
I was going to ask this as well and wondered if you tried advancing the timing slightly to help with low end torque to help with the spool. I'm also assuming the chain isn't overly stretched?
Also pushrod length and preload checkout good? Differnt motor could need shorter pushrods?
It’s all the same stuff as last time. I sure wouldn’t think so
@OverydeMotorsports right but if the deck height is different if could change what pushrod length is needed for preload.. though that obviously wouldn't get worse over time.
What version of Holley are you running ? Switched from v5 to v6 and spool time doubled went backwards and back to normal
I I’ve been one of the first versions of v6 for a couple years now
Gate hung open?
Definitely a possibility! I’ll check it out.
@OverydeMotorsports this would make sense, cause haven't you also had issues with it randomly making more or less boost and being inconsistent, would go inline with wastegate
@@stealthybrandon definitely imma dig into that asap haha
@@OverydeMotorsports maybe putting a ton of pressure on the gate. Could be cracking open under pressure
4 port mac for the win
Get rid of the vsr turbo should help the spool problems!!
Hahaha you could be on to something
While Ive personally had good luck with all my VS turbos......i would be really suspect of that turbo....
Get a Forced Inductions unit and dont look back!
Might go twins for next year! I would like to see what is up with this deal tho just to make sure I don’t start off on the wrong foot with a spendy engine

😂😂 that is so painful hahah. The times it didn’t wanna go in this video I was like dying in the car haha
Sounds like the turbo is junk.
Maybe so!
