Has anyone put a little supercharger on a V8 60 hp? At this point my question is, are the stock rods good enough to handle a low pressure boost. Want to run it in a little light weight modified. A little help in traffic and some audio tunes. Yes, I'm crazy but most of us are in this hobby, never happy the way it is. Thank you for your experience and answers. Jack.
I think they would be, they held up in the midgets at over 150hp on alcohol. Some here will know for sure though..Won't take long..
Seeing the punishment 60 lower ends took in our midgets, I would not worry at all about the rods with 5-6 lbs boost.
The rule of thumbs one here is, one pictures is teasing! 2 carbs is always a good Ideer, and find me one guy who is committed to mounted a blower, almost never regrets it, so I believe you should do it. Get to it, lad. [emoji41]
Also, most people assume that rods fail from horsepower...according to what I have read, on reasonably normal engines (meaning not blown fuel dragsters, Formula one cars, etc.) at high RPM the loads caused on the power stroke are MUCH lower than the loads on rod at top of exhaust stroke! Destruction is caused by distortion from the pull at high rpm rather than the push of high horsepower. And even there...full-floater rods are very resistant to the normal cause of rod failure, which is big end distortion caused by high RPM as noted above. Supercharging can get you your horsepower without high RPM, and so is potentially safer than many other routes to power.
Italmeca bowers were used on V-8 60s and back then you really didn't have much choice on rods, or cranks or ???? Cerrillo started producing after market rods in the late '40s or '50s ( I don't recall the exact date) and is pretty much the first to mass produce after market rods for the go fast crowd. One thing to remember is that any boost below 12 psi is just playing around. Not that it won't help your performance, just that it doesn't take a lot of lower end to handle light boost. it is not until you start boosting around 10 PSI that you have to start thinking about things like fuel supply and stouter than stock lower ends.
The 1940 v8 60's used a heavier rod and crankshaft ,but good luck finding a 40. I have a set of rods for a forty, still looking for the rest.
Thank you for all of the above, I'm still listening, still obsessed! Carillo rods for a 60 are 319.00 each. My reason for this question. You play, you pay. I my need a mentor . I'm " Gowin Old", still compulsive! Flatheads and Oatmeal, just love-em.
Me either but it's a long way from paintable and too much bondo for bare metal. It looks even worse in person.
Here's a 60 block with Triumph heads, no blower and ot, but thought you all may like it. Its different.
I had a serious hard on for that thing. But I might have need to correct you it's triumph barrels and heads. Not 650ccm. Special homemade block, possible Alu. Some say V8-60 crank, some say rods too. The engine is a ad speedy biil's speed shop. Built for the a lake tank, don't know of it ever ran. Sorry if I seem as a smart ass, I might be. And can't help my self.
Those look kinda like old Triumph motorcycle barrels and heads, except for the rocker boxes, exhaust ports...
Ha blow by, What do you cut up (. 2 carb manifold or original ) to mount the huffer on the 60. What about a pressure relief, pop- off? I like to do as much work on my stuff as insanely possible. Have a TIG, no Brigeport YET. My be a excuse to get one. Anyway, Sock-it- to- me. "Gowin Old". At 72 I still can't learn enough quick enough!
I hogged out a stock manifold but I have a 2x2 I am going to use next time I have it apart. Made my own simple pop off valve with adjustable spring tension.
I am working on a supercharger application on a v8-60. Mine is chain driven. A few questions. What is the ratio from the crank to supercharger to maintain 5lbs boost. Also, did you use a blowoff valve? If so, do you remember the make/size. Thanks. Daniel
