I was intrigued by the location of the turbo. You’d think it would have massive turbo lag.
I heard a rumor you used to work for Carroll Shelby back in the day?

Hey grumps:love_heart: Your help and constructive comments are always appreciated.
We're ALL home bound from this damn virus, bored, and like to share stories and pics to pass this stressful time. You don't need to come sing Kumbaya with us around the campfire, but being a negative nancy all the time, takes a toll on all of us here who are just trying to have a little fun.
No turbo lag to speak of, the sheer volume of air needed for positive boost is so great it's not an issue as long as flow isn't restricted.
Shelby? No I never worked for the man. I wish! I met him a few times though. Once repping his then brand new Shelby Ent. where they were just getting back to doing Mustangs for Ford, and again at the SEMA show about 6 months before he passed. Even in his little electric scooter, and looking every bit his age, he commanded such respect and attention wherever he went. Truly a mans man if there ever was one. His biographical stories are really just the beginning. A real blue collar genius

If it wasn't for us trying to keep conversations going, this board would be seriously dead. I've even resorted to taking jabs at njloco. Hopefully, I dont run into him in a dark alley someday.

I never knew he looked like Matt Damon. Have you ever noticed how much Dwayne Johnson looks like the Rock?
Anyhow, I'd have to imagine there is a blowoff valve constantly bleeding off air at at the TB, so when the hammer is down, boost is already at the butterfly. Seems like a bad idea to me, but I'm sure they figured out the kinks before they made a video and plastered their names all over it.
The rear mount STS turbo works exactly the same as any other. It can't build extra boost and bleed it off until you need it (thats *anti-lag). The wastegates job is to bypass exhaust pressure to lower max boost. The blow-off valve is on the intake side, and it's there for when the throttle blades slam shut. The intake pressure has to go somewhere thats not in the engine. If you close the throttle smoothly, the blow off won't even need to dump pressure the hungry engine will eat it just fine.
The extra volume in that length of pipe in the STS system is really inconsequential. Think about the volume in an intercooler as the same thing. It's really incredible how much air an engine needs to make power. Even at zero boost, mid-throttle, the turbo is spinning quite fast just to naturally not be a restriction, so it's not much to ask to add some more air on demand thats already flowing very quickly.
You don't need to fill that volume and then start making boost, it's already full and flowing.
*This young guy knows a bit about anti-lag. He's an OK driver, I hope he gets famous one day?:

The spitting and sputtering isn't a bad tune, anti-lag programming injects a ton of extra fuel (in this case methanol) to keep the exhaust really hot and make the turbos spin faster, so when he shifts they are already spinning very fast and can make boost almost instantly. The shock is hard on impellers though.
and a good example of how much air volume you need to make any boost at all:

Anything to help break the boredom, that's good info about turbos.
Have you ever seen Dwayne Johnson and The Rock is the same room at the same time!? Mind blown..

Having Fun keeping 6 ft from all. 
Thats a fantastic shot SR:eagerness: You got that big block in there fast! Any sound clips?
Bubbles asked "What's a brake stand?" I said I'd show her...
Next step, yummy donuts!

I dont think a 70 SS offered a 427, only a 396/402 or a 454. :angel:

HA! Thats exactly how to treat the outgoing engine
Is it anything special? I know a guy who could use one soonBubbles is rad. Definitely not afraid to send it. I told her to hold the brake, stand on the gas, shift at 4k, and modulate the brake for forward speed. First shot like a pro! Then it was hard to get the keys back from her.
I just got an old dry set of BFGs from the swap meet, just so she could burn 'em down
The ElCo is a whole lot more fun with the posi in it now and I just found a big box of goodies I used to have in the Blazer, line lock solonoid, a NOS plate kit, Autometer 6001, and even a stereo. Don't I have a different Chevy I should be playing with!?!:upset:

She did great!!!
The SB is a GM 350/300hp crate that came with the car He said it had 50K on it ya never know. It has no issues .
Nothing special LOL

For the back of the pickle fork.
Very impressive SR! Whats the power on that bad boy? I swear that squat bug catcher alcohol intake with short zoomies is the perfect look for an engine:love_heart: ALL business...
