1914cc motor hp
David Gandy
I'm looking at building a 1914cc motor (69mm x 94mm) and I am wondering
what
parts would be required with regards to heads, valve sizes, carbs, etc. I
am after
100 - 125 hp.
Can I use the 34pict carb on a motor this size until I save up for dual
kadrons or
webers or is 1.9L to big for this motor.
Thanks in advance.

David,
I hear nothing but complaints from the owners of Kadron setups.
I know someone here in Baton Rouge who has a '62 race bug. He is
currently running a 1914 w/Kadrons. It will push his light car to a
12.65 @ 101.something. There is no doubt that the car could go faster
with better carbs.
As for the 34PICT, I am running one on the 1641 in my Super.
This motor also has a cw 8-doweled crank, 12.5lb flywheel, Schneider #2 cam
(about 284 x .418) and 40 x 35.5 valves. It's an excellent street
motor, but the carb really can't keep up with the demands of 5000 and up
rpm. I don't think it can feed a 1914. It's anything but a performance
carb.
For the heads, I'd run a set with at least 40 x 35.5 valves, a
three angle valve job, and a mild port and polish wouldn't hurt either.
Hope this helps,
John

YOu can build the engine up to around 2200cc with the
stock carb.... but, the 1600cc engine is undercarbed already...
you would have SO much low end torque it wouldn't be funny....
hehehe
YOu will get varying opinions on the reliability of 94s on a
street car... I actually think they are OK ( go figure...) but
the case preparation is tricky for this bore size....
to answer your question in detail, you need to be more specific
as to what the engine is going in (bug, bus, T-3..... ) what
gearing you have, and what you intend to use it for....

require jetting as they come nicely jetted for a mild 1600-1700cc motor.
Personally I would skip the 94's and stick with about 90.5 max. This and a
modest compression rato of about 7.5:1 will give you a good reliable power
plant. With the Kadrons and an Engle 120 cam you should realize aboul 90
honest HP.
Headwork is where the most performance gains can be had from a VW engine.
Don't get too crazy here. Stock valve sizes and a decent valve job will give
you a decent street motor. The large valve heads are best used on Fast street
cars or race cars. They work on the street but normal street driving rarely
see over 4500 RPM. 3500 will give you about 65 on the freeway, so why kill it
trying to run 7000 RPM. I know, I've been there.
Before you build this motor you should consider exactly what you want this
car to do. 125 HP from a set of Kadrons id possible but not without extensive
work. 125 HP from 34 PICT carb, forget it.
Good luck.

About 1914 motor.if it is type 1.One way to do it is this.
heads:Stock or nothing else
cam:About 286-296 degree
garburator:one 45 dellorto or weber or tow of them
stock dont work.
distributor:bosch 009,or 094 or 050 are ok.stock can be used
extra oil cooler is good idea if you run long period fast
add extra oil filter.
I had engine this size and it runs well.0-400m 16.3 sek and
about 170 km/h.no i have 2.1 turbo and it runs wery well.200
km/h and i step out of gas pedal.No im working whit watercool
heads.sorry my english is not good.

94mm jugs require major modification to the case to fit.
The case can only fit 94mm jugs after that, and is considerably
weaker than with 90.5mm/92mm bores. Stay away from
them and go with 90.5mm's!!
90.5mm jugs, stock valves with a home done porting job right
out of " How to Hotrod VW's" , Engle 110 cam, dual Kadrons
and turbo or dual quiet pack. 009 distributor, 7 to 7.5 to1 c.r..
This is a proven set up, Good gas milage, great performance,
and it stays together.
