Re: REFLECTOR: Subaru run video

I had written the following to Alex but since Matt and Len have mentioned 
the Crossflow engines, let me share what I know about Crossflow and to 
caution folks to be VERY CAREFUL before you spend any money.  There is 
another Velocity builder out there that ordered and paid for an engine and 
had not received it as of a year or so ago.  I hadn't planned on sharing 
the note to Alex with the Reflector crowd, but since at least two of you 
are considering the engine - I didn't want to see anyone else taken to the 
cleaners (Dick paid as much for his FWF Crossflow, 4 cylinder turbo engine 
as I did my Don George Lycasarus IO360.)  I have 360 hours of reliable 
flying - Dick is still trying to get his airplane back home. 

Alex,
I wanted to update you on my friend, Dick Healy and his 4 cylinder, turbo 
charged Crossflow Subaru mounted on his Lancair 320 in 2004.

He has spent much of the summer in Canada after trailering his airplane to 
Crossflow to get the engine running right. (He got his engine after many 
delays in 2004).  They are on the third engine now (at least one engine 
was fried from running too lean), added an intercooler due to high 
combustion air temps.  The third engine has flown once and with winter 
setting in, it may be next year before they can confirm the flyability of 
the current setup.

Just wanted you to know that Jorge may not know all he needs to know about 
the ECU and engine operations.  On one of his trips down to NC to tune the 
ECU, he told Dick he did not think it was advisable to provide a cool air 
source to the turbo inlet.  You and I both know, the cooler the air, the 
better the engine performance will be (well short of carb icing - but 
these engines ARE fuel injected).  I couldn't believe Jorge had advised 
against the cool air scoop.  Now, he understands that not only does it 
need a cool air source, it also needs to have an intercooler to keep 
combustion air down to a reasonable temperature. 

Good luck with your engine - I feel better about what you are doing versus 
buying a firewall forward (rearward) from Crossflow.  They make a pretty 
engine, but I question his engine knowledge.  Last I heard, he has sold 60 
engines.  None are in reliable flying conditions yet!  Dick says there is 
one other flying engine at Crossflow, but it hasn't left the area yet.

Reflector Gang:  I love auto engines as much as anyone.  I have been a hot 
rodder for years, built several engines including a Chevy small block in a 
53 Studebaker coupe.  But, if you want reliable power for your Velocity, 
an engine that will keep you flying for a long time on a single rebuild, 
and can actually get pretty good fuel burns with a matched set of injector 
nozzles and good EGT/CHT monitoring (I get 8 GPH at 2600 rpm and 155 knots 
in my 173 Elite RG.  In a standard wing, you can add at least 15 knots to 
the cruise speed.  Oh and I hung my engine and installed all of the FW 
backwards in a little over a month.  Everything works as installed 
originally.  It starts easily, runs cool, and is very dependable.

Go for it Matt !!.....there are a lot of us who have ( or will have ) 
abandoned the 70+ yr old technology represented by  Cont  and Lyc.   I am 
leaning towards a GM LS2, or a 3 rotor rotary, or the crossflow turbo..... 
hard to choose.

Re: REFLECTOR: Subaru run video

Thank you. Most impressed here.  I have been toying with selling my IO540 
and going with something else. Deltahawk still has to deliver... I have 
seen the Crossflow site before.  Nice build.

Hi Matt- 
 I got a used engine with 48k miles on it- nice thing about SVX owners is 
that they take really good care of their cars- when I opened it up, oil 
was like new, still had the burnish marks on the cylinder sleeves.  I 
ported and polished the heads, replaced the stock high compression pistons 
with low compression ones for use with the turbocharger- removed the stock 
intake manifold, welded up a lower profile, and much lighter one, 
re-ground the cams slightly, and built the exhaust up one bend at a time 
to ensure that it would fit in the velocity cowling. Also had to re-locate 
the alternator for the same reason. I must add that I got a lot of help 
from Jorge Alonzo up at Crossflow Aero in Canada- he made the engine mount 
-which is a work of art- and I am using his ECU setup / wiring harness as 
well as their PSRU.  Intercooler is from a T-210 that I found on EBay for 
$43 including the pressure relief valve, which I have had reset to 5psi, 
and I have a Teil external waste gate to control the turbo.  Turbo was 
built by Majestic Turbochargers here in Dallas .  Overall, it has been a 
long road to get to this point- I suppose could have purchased a firewall 
back setup from Crosslfow but wouldn?t have learned nearly as much, and 
they are pretty proud of their 300+ hp units up there- 
Engine runs ridiculously smooth though- I think I am getting more 
vibration from the fuel pumps?.. 
PS- other nice thing- I can get an factory new assembled short block from 
Subaru for $3600- might just do that at overhaul time???

Estimated at 325hp at 4 lbs of boost- I can set the boost up to 16 psi and 
get maybe 500 hp- but I don?t want to put that much stress on the engine- 
I am more interested at getting somewhere near 200 hp at 20k feet- and get 
some good top end like  factory turbo model.  There is a guy who is 
getting about 1600 dyno wheel hp for drag racing in Australia out of a 
more highly modified turbocharged SVX- but I would guess that that engine 
won?t last too long at cruise power settings?  J

Is that the 300 HP motor?

Got a video up on youtube if anyone is interested- second run on my SVX 
motor- Milt Merskey on the camera with commentary- have an intermittent 
ignition coil on #5-  it comes alive at 1:48 and you can tell the 
difference- smoke at the end is from newly installed exhaust wrap ect??.. 
still have a ton of wiring to do, but this kind of stuff keeps you 
going?..
