My 86 Twin Turbo build

much respect for a guy who did it all himself in his garage. I just wonder if his welds hold up.

I feel the same way, thats quite a project he took on, I just think the muffler is hillairious

 
Rep Power: 729

well the idea is smart. instead of welding himself a carn hot box he used a muffler, just wondering how its gonna run.

silly question but does he have bov's

or do you need them with carbirators ?

props for doing the unusual stuff, i know all about it

i turbo'd a saturn you should see the looks i get

if it gets good numbers, it gonna be a cool sleeper

You dont need a BOV at all, carb or injected.
People just like them because they make a funny noise.
They may be a little easier on your turbo, but my car is 20 years old with the original turbo and it is still in great shape.

I give that guy props for doing a driveway build like that and using what he had lying around.
That is grass roots hot rodding right there.

what about compressor surge
when the throttle plate closes

is that only on high boost cars, cause i was under the impression that its usually a good ideA to have one

 
Rep Power: 731

Its not a bad idea to have one just not necessary.
Some others have a different thought on this and I`m not an expert on turbos but I have seen dozens of GNs and other cars with boost levels well over 20 psi with no bov and no issues.
Just makes a different noise when you lift.

More effective on a manual transmission car, because my GN is Automatic (as are the rest of them) the only time you'll get the Turbo "Sneeze" is when your done boosting the snot out of it.

the damage you can cause is to the thrust bearings inside the cartrige, but it's much worse with the manual because your on and off the throttle so much.

I try to roll off the throttle so the sneeze is not so severe, but to be honest Turbo Longevity is not an issue with the buick guys, the only things we see are burned exhaust wheels from a lean condition (Nitrous) and anything going through the turbo is never good...

I might also not we are having great sucess with the Ball Bearing turbos, they spool up almost instantly.
