right this is how the engineer fellow did my center main strap. he races midgets and this is how he does his. now ive run this last year and all seems fine and i have no intentions of changing it but thought it might be interesting for people because ive never seen one done this way before. oh and i would like you opinions just out of curiousity.
no longer a series, but still 1.3 turbo.

Personally I prefer to see more of the cap machined flat so as the strap supports it more.

But maybe with it machined this way it will ensure pressure is applied in the most important places?

i have not broken caps but i was advised after one of my engines went bang that due to not using the strap a failure at 6500 rpm on the rollers, i was told the crank was flexing which caused the end cap of me conrod to fail.....of course this is no doubt bullshit. but at the time seemed plausible

personaly i would machine flat as the strap will support the whole of the cap, the way he has done it to me looks a waist of time. always looking for them bigger bunches of bannanas |

I agree! I think it will be up to the job!

The engine builder i use is one of the top mini builders in the country imho and from what i've heard. (think he built endaf's miglia engine?) To be honest i dont think that the standard cap needs much more support so either way works equally as well.  1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

mines machined flat, the radius'd bit has been left a couple or mm thick either side and the cap has been notched out to accomodate if that makes any sense! On 1st Mar, 2009 MikeRace said:

Well, there are two ways to look at this: Remove the material from the cap such that a cast component is now weaker than it was before you started, and support it with a sizable lump of steel - or - remove enough from the cap to achieve a surface that you can suport properly with a lump of steel.

the spacers where machined exactly right dave, i really cant remeber exactly what he said but it were like he did it with half a ftlb of nip on the top or something like that. (dont quote me lol i have a habit of not listening properly and just thinking hmm that looks cool) no longer a series, but still 1.3 turbo.
