>Well, yeas and no - it's car-dependant.


We can agree on that.  That's why I keep saying things like this:

>> The SVO anyway, and my home-built >full throttle as appropriate.
>> The SVO has NO turbo lag.  None.  At all.  Its factory turbine


because I understand that (and you maybe thought I kept repeating the word
"SVO" to brag, huh?)  <grin>

>Either that, or your max boost pressure is very low. What does the boost
curve look like on this car?

Factory boost on the SVO, as I've said in the past, is ~15 psi max (does
anybody actually read these posts?).  All the boost is in by ~3000 rpm or
so, and tends to creep *up* at WOT and max rpm, not down (the gauge reads to
21 psi).

>A stock T25 Talon makes about 14-15 PSI at 3500, falling to 8-9 PSI at
7400 -the tiny turbine can't move any more air.

Bummer for you, though.  The SVO is adding boost at max revs, not losing it.
But the turbine and its housing, though, have nothing to do with boost
*falling* at high flows.  The *compressor* and its housing might, if it's
falling into very low efficiencies, but I'd suspect something in the factory
engine management system instead.

>What's the displacement of this car?

2.3 liters.  With legal SP mods, it makes about 100hp/liter minimum, and
will be making more with the rest of the legal SP mods.  But I need to
concentrate on suspension changes, such as the 65# roll cage that'll go in
this year if I'm lucky, etc.  Don't need any more power now in a 2900# car,
I'm matching the Camaros for power-to-weight already, now I have to play
catch-up in the chassis and in skill.
