The VAM is a form of mass air. It's a very primitive version of it.

All Ford EFI 2.3T's are VAM mass air.

oh ok thats what i was thinking,

BTW does anyone know if the stinger 3" exhaust has any hangers or brackets or anything with it? all the pics showed was the piping

Nope. No hangers.

i even made a bet to have someone disconect the shaft on the wastegate just to see how much boost the turbo would make under a full throttle load.. i had no takers on the bet..

The '88 Murkur(T3) I had would make 25+++psi when the wastegate actuator diaphragm was bad... Till I could get a new actuator, I just tied the WG slightly open... Was a pig(automatic) till about 4000 RPM then took off... I must say it was a decent performer with the new actuator... Course it didn't weigh nuthin', was like puttin' a 2.3T on a roller skate...

Ran mine at 18psi(when i had it) with a gillis for quite a while on an automatic and stock wastegate to boot with not a single problem.
Hell right now i'm running almost 15psi with my vortech supercharged 302 when people say that the stock bosch bypass will only handle 10-12psi.
It all depends on how much you beat on your car and the quality of it's parts.
My opinion is on your particular 2.3L in your application it's not necessary or worth it,but if you must you must.
As stated by 306 who is also running around 500hp with a supercharged v8(if i remember correctly)we've tried to explain it and you don't want to listen so to each his own,it's not gonna hurt the car if you install one it's just not necessary.

thanks for the info guys you've been tons of help!!!!

i just tore the front clip off the car and i'm going parts hunting tomorrow for a header panel, fender, bumper and a door... hopefully by spring ill have the car running and i can put some money into it for mods

btw Chuck W: wow i was looking at ur gallery and man that tbird is amazing, i hope my cat is at least half as clean as yours when i get done, i love how you blacked out the headlight buckets, it looks awesome

No one said that it would necessarily hurt anything, below 20 psi you'll probably never have a failure, but it can reduce turbocharger life potentially. A proper BOV/BPV also improves lag time between shifts and in general helps with driveability if done right. There's a reason pretty much all OEM turbo cars come with them. The stock Fords didn't because they had a very small intercooler and piping volume that would not create such a large reservoir of stored up pressure that would have to be released through the compressor wheel BACKWARDS when the throttle is closed. So with the stock IC you get by.

This doesn't change the fact that wastegates and blowoff valves have nothing to do with each other, they do entirely different things effectively.

I also heard about turbo lag. A BOV will let the turbo spinn freely until you get the boost going again,a little more performance for a guy if he needs it or not. I will prob do one on my latest project because i will want the turbo to spin instead of backspin. Thus it will boost up faster between shifts.

Thats exactly why. A BOV/BPV vents when you shift or release the throttle.

a wastegate bleeds off escess exhaust gas when it reaches the certain pressure you set it at. It keeps the turbo from spinning indeffinately until something blows. It does it the whole way up the RPM range, it's what creates the wooshing sound of a turbo... if anyone reads MM&FF they did this amazing right up on how they put a wastegate on a centrifugal supercharger, it allowed them to run the smallest pulley(highest pressure) and then set the wastegate at like 15 PSI so that way the pressure was at almost full boost at like 1/4 throttle

BOV just releases the pressure in the intake tract so that was you doint get a revers pressure when the throttle blades slam closed between shifts, it lest the pressure escape so that way the turbo can spool up a lot faster, takes a lot of stress off of the bearings the two can't be interchanged wastegate is used in the "hot" section of the turbo and is related to the pressure from the exhaust gasses the BOV is in the intake andd is on the "cold" side

am i right????maybe?? lol
i think i have a grasp on the difference between the two

is their anthing that i missed out??? i here to learn!!

a good read is "Maximum Boost" by Corky Bell

Before you spring for a Gillis valve or similar, try disconnecting the lines to the BCS at the turbo, connect those two points with a length of vacuum line.

A bypass valve releases pressure from the intake tract by recycling air into the intake tract. A blow off valve releases air from the intake tract into the atmosphere. "Which do you need?", is usually answered by, "Where is the VAM (or MAF), before or after the turbo?"
"before" = bypass
"after" = blow off.

From Wikipedia

Quote

A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. Diversion of exhaust gases causes the turbine to lose speed, which in turn reduces the rotating speed of the compressor. The primary function of the wastegate is to stabilize boost pressure in turbocharger systems, to protect the engine and the turbocharger. The wastegate is controlled by a wastegate actuator in which the actuator is controlled by pressure coming from the intake manifold.

In simple terms, the wastegate sets the baseline amount of boost a mechanical supercharger (in this case, your turbo) produces.

how do i "turn up the boost" i'm thinkng of running like 15 psi is that what the gillis valve does??

btw i checked out 40bob.com and they didn't have any gilis valve stuff listed

Just try the vacuum line, and make sure you've got a good boost gauge.
