Small powerhouses and old school

[Pas]

I'm kind of missing that clutch smell which accompanied meal times at the track

Or even missing meals while changing clutchs/pressure plates

Sounds like someone needs their own BBQ chef 

The car looks and sounds awesome Peter, roll on this years racing season

Hello there,

Just a dyno pull of my 1915.
69mm Demello
JE pistons
5.4" rods
MS230 46x36 valves
11.2:1C/R
Raptor valvetrain
F1 throttle bodies
Motec M4 ecu

Will soon be updated with raised c/r, top shot injectors and new header.

Does the input valve is close to the cylinder.

greetings everyone once again 


looking at the masterppiece that mr. johannes has  designed
the mouse 1603cc motor,


ofcourse power is not even a question based on the results, it made tons of it
and driveability is ideal  too i suppose...


i have an odd question, hopefully udo or jpm, or any of our seasoned builders can clarify


with the aproach of the mouse 1603cc motor, lets say.. adjust the cam and compression to suit a circuit application
will the non counterweighted crank, using super light JE pistons be ok to use in sustained high rpm ?

i know drag use is alot different when ur turning into a mild curve into a long straight where u are atleast 5-10secs in full throttle above 6k rpm ,     would the non counterweighted fullybalanced crank and itnernals with JE pistons be ok?

or is it best to go with a cw 69 in this instance of application?

thanks guys

[Udo]

I would go with an original conterweighted crank . But the more important thing is the ballancing, we did highspeed balancing úp to 8000 rpm on all race engines during the last years . It makes the crank live longer and i think it does not flex as much as it does before . Up to 7000 an ogininal crank is ok

Udo

[RFbuilt]

Thanks udo ! Such an amazing source of knowledge you are

But to clarifiy "original counterweight" u mean welded like DPR?

Yes sir we balance all our internals on a schenk engine balance machine

Lastly u mention on an "original" crank when fully balanced it is ok to 7,000 rpm it doesnt suffer flex as much
Did u mean original non welded counterweight?
As u mentioned for counterweighted it is safe up to 8,000rpm

Thank you

[Udo]

All yes , this is what i found out . In the earlier days we used original non conterweight for our race engines up to 7000 with no problems.

Udo

[RFbuilt]

thank you Udo!  i may have to try this   with an autocross/circuit project hehehe


thanks for sharing your valuable experience ! specially in circuit racing from before

I've been running a 1776cc street /strip engine for a couple of years now and it's still going very strong.
I use the car as a daily on a regular base and racing it in weekends.
It's a full steel 73 car and I'm running an ET of 14.5 @91 mph .(slicks and short 3/4)
Engine has an estimated 125 hp and is built with a CW crank 69 , std  rods , Cima Mahle 90.5 A kit and a Webcam dual lobe cam.
The heads are 041 with 40x35.5 ported by Steve' Heads and 48 IDa carbs.
The whole engine was planned as a streetable engine with good response at lower Rpms and still get good top performance.
I generally set the RPM limitor at 7600 rpm for racing .

I agree with Udo , that to make an engine "drehfreudig" and get high rpms easily is to give it a very good balancing .

Well ,hope to see you all (most of you ...) in Bitburg next WE .

sounds like u have a nice super streetable 1776!    full weight bug.. excellent   

[johnbitch]

Awesome thread. I love small engines.

Here is a short vid of my 12oocc, maybe one or two of you lke it...

[mr horsepower]

you need shorter gears.
for the rest is sounds awsome

gr henri

[johnbitch]

Thank you for that.

The video was taken with a stock german 12oocc transmission.

Next year I want to race the engine with a mexican 1600i tranny, which is, as far as i know, shorter than the above mentioned.

[andy198712]

i thought the 1200's all had really short boxes, mine does  bit of a pain to drive above 50mph!

has anyone seen the 1200 power contest? winner was around 150bhp at the wheels

Here are some photos of the jigs and crank for my friend Stanley's mouse motor:

Nice!

would it be more?

Nice!

More?
Could I take off more? Yes. But this will do this time around.

Kalle,

Nice so it works then

cheers richie 

[mrmut]

long time follow what makes Kalle this project was followed out much HP and Nm , but one interested that camshaft of Raptor and which turbo to achieve this

[Andrimot]

Nice job!

But why on a turbo motor?

Hi loungers i hope this is the right topic to ask my question.
A few jears ago i got hold of a pair of solex 40 pt-4 carbs and intakes  they were verry worn out .
But i liked the way the were worked by hand some body had a hard time on them .
I think the came from a old autocross or rally engine i liked that just to own it
4 jears later a buddy of mine got hold of a set of hand worked old race heads
They have 40mm intake and 32 ex valve
he told me ill could use them to make and engine for display with it nice i thouged
when we looked at the heads and the intake i sayed the look the same as my old school carb/intake set
So i pulled the carbs out of the dust  and placed them on the heads
And then the amezing came .
The match the same as dna on peolpe!!! wauw!
I thouged thats cool ,
So my buddy says lets put then on a flowbench just for fun and the turned out to flow 160 hp!!
But i i consider them to far worn out to use
But i have an 1956 ragtop oval bug that needs a bigger engine and i like old school
And i gonna try to rebirth the old engine parts, But there are cracks in the heads and now i want to now can the be saved i hope so.
Can someone give me advice on that i don t want to use new parts only period time parts  and work to keep it originel and give the builder respect because for me its a part of history that i want to restore
Here are some pics

You gotta love that crank jig setup... Very cool!

I was thinking the very same thing dude

1655cc and 255hp at 10.600 rpm....

Cool.

I drive a hot 1776 engine for 4 years now in my '57 single cab, it uses 40IDF's, a counterweight gene berg crankshaft, autocraft rockers, gene berg camshaft,...CB 044 CNC round port heads,kennedy stage 1, csp phyton exhaust
The thing is...when we where putting it together I checkt the GB camshaft number, but forgot to write it down, I know I looked it up and it said, mildly wild, for streetuse,...
Anybody any idea witch berg camshaft it is??
I'm planning to put the engine in my bug so the engine can finaly be put to the test, cause the high reving nature of the engine is no good match with my heavy bus.
With the right gearbox it takes my bus under 18sec. Even with the tarp on.

[peejke]

Its prob. a GB297 , same as engle W110.

[ida2332cc]

wow this thread is awesome. have been loving reading it. i personally love the mouse motors.
i built a 1835cc mouse motor about 12 years ago running a best of 13.01 at 98mph.
with a stock 1300 gearbox. i will be building it up again this time with a box with better gearing.
specs on mine were as21 case cleaned and de burred and all sharp edges raidiused.
69mm crank from 1300cc engine. I lightened and polished it. ( lot of ours) & not counterweighted
stock rods lightened and polished.
mahle 92mm piston and barrels. lighted and notched for valve clearence.
lightend vw flywheel then bottom end was balanced.
cam was a grind of my own spec which i wont give details on.(sorry)
heads were 044s 40mm inlet 35.5 exhaust, ported by myself i even ground off valve guides inside the ports.
40mm dells
comp was 12.2:1
and i was shifting at 7800rpm.
this small engine was alot of fun and it never broke in the 3 years i drove it and raced it.

[chopper476]

try and get this thread up and running again as its one of the best and most interesting threads ever! ian clarks 52 suited the theme of this thread very nicely and out of personal interest, does anyone have any specs of the later 1850cc motor it ran?
