Max boost of super 70

[moparzrule]

Whats the max boost pressure that a super 70 can handle? This is with the .63 stage 1 turbine if that matters, and also this is the buick GN wheel from TU not a t04bs. I mean boost pressure before the IC, what can it produce before overspinning?
Edit-Please note that I'm talking about boost before the IC.

I would like to know also. TTT for ya!!

Hmmm...sounds like a loaded question to me. Stock exhaust? Ported head? Ported intake? What kind of IC?

[moparzrule]

mods are in my sig!

Lock the wastegate and go for a drive, lol!

Don't give me ideas

I don't think I'll have fuel for that high, plus the 3 bar MAP sensor is done at 29 PSI isn't it?

Doesn't matter. It's all in the "current" bottleneck.... You can get 30psi off a stocker at the turbo... Doesn't mean the intake is seeing 30psi (pressure drop) Or the exhaust can't flow enough to make it worth while...

30 psi on one car is NO WHERE near 30 psi on another car. That's a misconception that needs to be made public. Similar mods are a "good" guage, but not perfect. Hell, I'm worried about my I/c now (twin stocker) With what I've done to the car, will it be enough??

I have an S70 on my Daytona. It "resulted" in 2.5mph gain over the stock turbo at the same boost. The t3/4 resulted in 3mph gain over the S70.... (this was on the GLHS) I know where the bottlenecks are on the Daytona...just need to address them.

I know all that^, in my first post I edited it to say I wanted to know how much boost it's able to produce at the outlet of the turbo NOT at the intake. I have an autometer 0-35 PSI boost gauge that I plan to run off the nipple of the turbo.

What is my bottle neck? The stock turbine wheel?

It'll be enough Ken, otherwise more money to spend, doh!

I need to get me a T3/T4. Need all the help I can get to move my aero-dynamically challenged van. Thats very impressive Ken. What was the bottle neck there?

The stock head.

Rule, That's the point. If the car can handle it, it will suck alll the air the turbo can throw at it. How about a t3/4 that would not build more that 28psi?? The car ate the air. Another car the same thing builds 35psi no problem... stock head...

There is no max it can make at the outlet.

[moparzrule]

Oh I see, cool. So what do you think would be max for my setup?
