I agree with you Ronnie- we have had discussions about Crossflows ability to
deliver in a timely manor- that is why I used only parts that I could not
easily build myself- ECU, mount and PSRU- all of which are made very
professionally- I can tell everyone that if you decide to go with them,
figure on about 2 or 3 times the lead time that they tell you- Jorge does
know a lot about the engine though, I have tested his knowledge many times-
that being said - I like their engineering, but they are by far the worst to
deal with as far as customer service goes. I have just found an
outstanding tuner that will be helping me to precisely map the ECU- if
anyone is interested: C&C fuel injection - David- 775 329-9974 they have a
ton if experience with all types of ECU equipped engines including some Reno
air racers-
My advice- save a lot of money and time, and learn a lot about engineering
and brew your own if you are able- whatever you can not build yourself, can
be bought from various sources including Crossflow- ,maybe Egenfaller, and
others

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...
Alex

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. :-)

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...
