[urq] More boost : what is the easiest, fastest, safest bang for the buck ?

[dgraber460 at aol.com]

Phil;
Is that really you? Haven't heard from you for quit a few years.
You were _very_ instrumental in bringing my old URQ back to life with factoids and encouragement.
Good to know your still kickin. You've been missed.
How's things on the "other side of the pond"?

What do most people commonly regard as the highest safe boost level for a 
tandard head gasket?

Schrappnell Knobben requires no mods at all to the WG ... just attach a boost 
ource and pressure regulator to the fitting on the cap.  If you want the 
stiffer" spring from idle you can install a pressure accumulator and check 
alve in the line.  Since you have the nodded EVIDENCE that should be all you 
eed.  IME this will broaden your grin significantly.

Now that my stock urQ is repaired, and since it’ll only see limited road
uties for the foreseeable future, it’s time to tamper with it a bit.

First, more boost.
My engine was recently rebuilt, there is no issues now, and the car is
trong and powerful, as in 160 hp anyway. It feels faster than that modest
utput, even to my car buddies.
I already have a chipped ECU (supposed to be a Lehmann ECU according to the
revious seller), but still the stock spring. I don’t know yet what is its
ut-off point for overboost. I will also have access to another chipped ECU,
rom another car that is awaiting its built 20V in the shop as of now. That
Cu was bought from Andrew Finney, or another guy on the urq list from
alifornia IIRW…

I just want to give it a little raise in HP, as much as a 2.0 bar boost
ould give, that’ll be fine for me. According to my master tuner, Brady from
he Dynodoc tuning shop here in Montreal, K26s don’t like more than 2.0 bar.
e have 94 octane fuel here at Petro-Canada, about a mile from my home, so
his will be its regular diet.
Faster ice racing laps is my goal. Read, more snow spray at the back of the
ar to impress the youngsters…

Should I :
1-      Do the shrapnel knob mod on a spare wastegate ? Adjust with a boost
auge or until boost cut-off.
2-      Install a manual boost controller on the pressure line of the
astegate ?
3-      Install a manual boost controller on the top nipple of the wastegate
ith a supplemental feed line from the intake ?
4-      Buy a 45$ 1.9 bar spring from 034 ?
5-      Find a 2.0 bar spring elsewhere ?

Second, a bit of exhaust sound would do the trick too as good noise=speed in
he eye of these same youngsters…
The exhaust is still stock. And I want to keep the twin tailpipes as they
re.
I don’t use a cat, it’s now a straight pipe with a flex, attached with two
 in long 65 mm collars from a TT. The exhaust is still 65 mm all the way,
