700 on standard rods? We know cossie Dave's crank let go at that, I am sure the rods would not be safe at 700 and 8000 rpm.

I will not venture above 500 without arrow crank, rods, 10 long studs, pocketed Pistons, cams, head work and a very good oil system and breather.

That really would be good fun, get some timing gear on the cars and see what they could do. I really want to try one full bore launch, 5000 rpm and step off the clutch and see what it does....I haven't done it so far as I don't want to break anything but it's got to be done once.

Was he on standard rods when the crank let go?

The rods are strong enough for 700hp and 8k.

I wouldn’t say for a lifetime but they will hold up if the engine is built correctly

How many engines have you built and used at that power level to state this?

The stresses under load on a rod is so high that the estimated lifetime (number of cycles before failure) drops exponentially.

I broke a standard rod or the piston gave in it’s hard to tell there both beat to death lol with 500 ish bhp. I guess it’s the luck of the draw. Problem is these parts are not cheap so it’s best to take the risk away

None.
But I know who has.

Rods could fail at 1000k or 10,000k but they are strong enough

Spot on, sometimes you can’t tell what gave first, but obviously for reliability it’s best to upgrade if you can

Rods will break far sooner due to rpm loadings than they will power.

And Cossie rods are pretty damn robust looking items

Midlands i am too been around a long time what cars were these maybe seen them

Edited as im a blind cunt and just looked at your sig links lol just back from 10hr drive awesome motor that mk2
Last engine had two years of abuse reving to 8800 rpm and as far as I know that engine still hasn’t been opened or repaired in 6 years but it was de-tuned to around 400hp

I wouldn’t build a engine to run 700hp on stock rods as for me it carries to much risk as they are very old and fatigued and if one lets go it kills everything.
I would map a engine to that if I was asked but I would make the owner aware of my view.

Out of curiosity mark if the standard rods where new would you think they would be strong enough for 700bhp if the rpm was sensible? I wouldn't do it personally as I know the longer rods are better but cool to hear the standard ones where so well engineered.

I would still change them as at that level you want to be looking at longer rods to help with the load on the bores.

Being not a Ford...surely for any racing classes it's the same as a engine swap anyway as far as rules go ?

There's a lot to be said for moving to more modern stuff, even if it can also be a large investment to make the change. But could probably still be done with supporting mods, intake/exhaust etc for less than a S&J ?


But they are very nice looking engines...as much as there is probably a lot of merit in the long stud design where it goes through the main caps. I wonder how that pans out on real live ?
ie how's a head gasket swap ? Easy or hard ? things like that
Good question that mate so I asked Steve at s&j he happend to be working on one and sent me some pics

Apparently they have some customers in the 800hp range.

Would be interesting to know how long they've lasted as rods has run upto 840 hp on an old 200 block, if there alot more reliable could be the way to go

I'd imagine as they are race cars....they probably covered more road and race/stage miles than Rods.

Certainly the later block design with the studs that screw into the main cap is good vs the older which had studs into the alloy. Although it would be nice to have a top hat style liner in the block, with an iron surface for the gasket, rather than the thin liner that is in place in the photos.

I did have a link somewhere to one of the race cars, no idea where it is though. It was a rally/hillclimb type Escort in Europe somewhere.

When I was speaking to Steve he said thiers a few at 1000 one planned in Malta at 1200 and one in Germany planned for 1500 he said the first few out of the mk2 batch had teething issues the issue was rectified, over 50 out thier now no issues

They are rated well into the 800hp plus area I believe

Ag focus was/is over 900 on the old style alloy block so the through stud idea will be a walk in the park at 1000. They’ve done an iron through stud version which will be even stronger
