Hello-
| Quote: | | The offset shaft concerns me a bit. |
I have to admit I have the same concern. More specifically, I'm wondering if I took the money it would cost to install these ratio rockers, and put it into head porting, could I achieve the same results? Hmmmm.
Cheers,
Paul

Sweet!!!
what ratios are they available in?
what is the retail price?
I'm not worried about the offset shaft for one simple fact: Put enough valve spring on a 36hp enigine to break those shafts, and you'll wipe out the cam and lifters, first 
Bonneville Tom made a set of offset shafts very similar to these several years ago, has run them with very good luck. Maybe he will chime in. |

Tom Bruche ran the same style on his bonneville car with 0 issues, I have them on one of my engines, no problem so far and I have some pretty heavy spring pressures.
Just an easier way to get some more poop from your 36 hp engine with-out splitting the cases to put a bigger came in

You could try... but at some point, you will want to increase lift of those valves to take advantage of a better port. With cam lobe height being limited by the 36hp lifter design and lack of available cam blanks... |

machine case for cam bearings, machine the lifter bores in the case to accept the 356 lifters in a straight shot instead of angled like they are, then run custom .080 cromoly 1pc pushrods, then weld up the cylinder stud holes in the case and machine case to accept 90.5 p/c's, porsche rods have 22mm wrist pins  , use type 1 heads and rockers... oh sorry got carried away didnt i...lol. |

type 1 heads will not fit (other hole pattern), try to weld that old aloycase  good luck but for sure you can use a pre 50 case
and why all the work on the case for the lifters. i had a rev limiter at 7800 rpm because my engine wanted more on a 36hp.....there are different ways easyer and cheaper to make a engine breath. had 12,x mm valvelift a lighter valvetrain as every formulaV engine and this out of stock parts with just some tricks and porsche 1,3:1 rockers. and drove it 1000km+ autobahn, berlin city +++ and the cam and lifters and all the other stuff is in perfekt shape like on the first day.
the speedwell rockers are a good part. the price is still interesting for me. 1.6:1 would be nice too. but 1.4 is for the raver a very good deal. i had 1.35:1 ratio with the porschelifters but hte time and coast was huge. cost about 250 euros but machining time and searchtime amazing high.
so what is the price for a set of 1.4:1 ???

| hey gruni, how have you been? when i said weld up the cylinder stud holes in the case i was refering to redrill them in the type 1 pattern so you could use type 1 heads. if you do that you open up worlds of possibilities with a 36hp case. use a offset ground 76mm or 77mm crank, 90.5 p/c's, and you have a 2liter plus sized 36hp motor... again i talk about and do these things because i can not because i should or shouldnt happy motoring |

the stud holes is one thing the cyinder holes another thing typ1 is wider. but you could use superexpensive porsche 356 heads after redrilling them to porsche 356 because they are the same.
with 1.4 -1.6 :1 rockers a 77 or 78 mm crank could be make sense.
if you have the money the physics and are your only limit.
you can't change the point between one rod and another so you have to keep the hole pattern of the cylinders. and cut the cylinders is also not good. but plit ports hardly changed could work if you do a new rockerdesign. that is same work than do new billet 36hp heads.
here is a link to the motor you wish to have:
http://www.rs-motor.at/
they have a billet 356 head. with 48/xx valves 1,6:1 rockers and build for 90.5 cylinders...its about 3500 euro if i am right.
contackt them.
use a alloy case up to '50 redesign it for 90.5mm pistons
use a 78.4 porsche 356 crank (saw last year on maikäfertreffen one)
and you have a high potential preA looking porschemotor based on a vw bug case.
btw i have a project laying around that open limits like typ1 and its pure vintage stuff.
