Hi Guys,
I just cameback from a week of XC flying all over the Southern US.
One of mystops was a visit at Don Rivera's Airflow Performance World Headquarters
in Spartanburg, SC.
He and one ofhis technicians (Kyle, if I remember correctly) spent one whole day
to tweak mysetup.
We got thecylinders to peak within 0.2 of a Gallon FF and bumped the fuel pressure
up toprovide a more generous supply of the Blue Stuff.
Aftereverything was said and done I left with a wonderfully smooth running engineand
due to my reset fuel pressure (36 gph on T/O)even more thrilling T/O performance
than I had before.
Dons outfit is immaculate, everybody I met was extremely helpful andworking with
them was a real pleasure.
I can highlyrecommend his products and his operation.
Cheers
Wolfgang

DOES A CERAMIC COAT ON BOTH INSIDE AND OUT MAKE THE PIPES HOTTER, AS IT MAY CONTAIN
THE HEAT, AND THEREFORE PIPES CRACK OR FATIGUE SOONER?

John Forsling makes tuned exhaust for BPE Cold air. He is recommended by
Allen Barrett. John actually spent time in BPE's shop and built several
exhausts and ran them on BPE's dyno to see what worked and what didn't.
John used to work work Vetterman before going off on his own. He's not
an e-mail/computer guy. e-mail me off line for his phone number. I have
his exhaust but have not installed it yet. It's ceramic coated inside
and out and priced competitively.

I understand that John Harmon's exhaust is designed to fit the BPA
setup. Hard to find a cheaper exhaust and you know that heaps of them
are in service!
Good Luck
Tony

Hi all,
Today I finally got around to installing my cold air induction and
inverted
system. Of course I left the exhaust to last. I have been running a
Vettermann system, love it and people tell me it sounds great on the
ground.
Problem is that it interferes with the BPA cold air induction piping.
Does anyone out there have the BPA system? If so what exhaust are you
running and where can I get my hands on one?
Regards,
Jeff

I have no 1st hand experience, as mine are not installed, however I have
heard from an EAA chapter member who had his coated after he had been
flying that his EGT's rose 75-100 degrees. I have heard anecdotal
stories both ways. i.e. that is shortens the life and that it extends
it..... ?

Hi Mark,
The cost for this service including up to (4) restrictors is $300.00.
Cost does not include new injector nozzle assemblies if required.
I am running an Airflow Performance FM 300 Servo which has one main jet.
My main jet is a #40.
My initial setup started with .028 restrictors but we changed them on three
cylinders to get a more balanced flow. Changing one restrictor will change
everything else so Don's experience was invaluable. Everything was said and
done after one test flight. (you need to deliver data upfront).
Concerning the airflow capabilities of your servo I can't give you an
answer. Mine flows in excess of 2200 pph for the 36gph FF and 40" of
manifold pressure I use one T/O.
Cheers
Wolfgang

Ceramic coat lowers the transfer of heat rate through the walls over a
longer duration of time. Lower cowl temperatures, better fuel flow.
In Lancair's running the TSIO-550 it has been said that the ceramic
coating can flake off the inside and kills the turbo. I have heard no
first hand reports to confirm the perception. When only one side is
coated, the uneven cooling increases cracking at the flanges and welds.
That has been documented but not directly linked to the ceramic coatings
- it could have been questionable welds.
The benefits versus perceived risks need further research. The lower
cowl temperatures are a big plus.
