To be honest I think the oil wasn't warm enough! Its got a hard cut at 7200! Plus I drive it like a stole it so Never mind! It's more annoying the fact that I've been waiting 8 weeks for an oil pump on my dry sump kit!

Also had an oil pump go at 350bhp so I personally think it's got a lot to do with luck! And that oil pump went on the dyno!

The most convincing theory about Zetec oil pump failure is about resonance...Get the bottom end balanced, add a billet oil pump and failure is much less likely.

Or just fit the dry sump kit I've got sitting there lol! Just waiting on the pump and she will be mint, raise the revs to about 8.5k gtx35 and aim for a solid 550! Then give it death! Lol!

yea are oil gauge is right in front of us and we got a big red oil warning bulb on the dash, it just luck of the draw, we have polished are pump P.R.V and up rated the spring, just in case it gets stuck open.

Assuming you're on an 86mm bore, the mean piston speeds you'll achieve at 8500rpm will most likely cause rod bolt failure...

Good figures but why on earth would you use a gtx35 for 550hp ! Its a 700+hp rated turbo.
Bad luck on the pump failure, hope the pump is the only damage.
Harmonic damper and a proper balance would be next on the list really but I guess the dry sump with resolve the problem.

It's more for the fact that the gtx 35 will achieve that hp without it being near its limit and will give a better spool time then a normal gt35! That was my thinking anyway! Might just change the exhaust housing on the my gtx3076 first and see how that performs!
Big will... Didn't know rod bolt failure was a problem at 8.5k, that would be where the hard cut limit will be set at anyway! I will have a look into it but never heard about it before! Ive been more concerned about the valves to be honest!

Finite Element Analysis of connecting rod structure highlights the areas in which the load concentrates:
When you think about it, the piston is travelling up the cylinder at horrendous speed, then the bottom of the rod cap is responsible for containing the rod and the piston accelerating (in the region of 20-25 metres per second!) - and the only thing holding that cap on is the connecting rod bolts!!!
As such, you need to make sure your piston speeds are 'safe' - otherwise its very likely the rod bolts will fail in time.

The geometry of the engine needs to be considered before raising the revs, the bore diameter, crank stroke and rod length need to be analysed to ascertain the stroke to bore ratio and the mean piston speeds.

That sounds a bit too far in depth for my knowledge so maybe I won't rev it so high! Although there's a lot of N/A Zetec's which rev quite high and I'm sure there's nothing special with the rod design or bolts, just standard forge rods and arp rod bolts!
To be honest I'm going to fit the dry sump kit, change the exhaust housing to a .82 and take the revs up to about 8k and see where the power tails off, obviously theres no point in taking the rev limit higher if it's not going to continue making power! The main reason I want to rev a bit higher is so that I can reduce a gear change when going up the strip so I can cross the line in 4th!

Right well I may aswel up date you all, oil pump let go on me on Saturday, and I spun all 4 shells! So, some new Rods, a crank and some shells later I have a new engine built! Couple that with my dry sump kit which is in the process of being fitted, fingers crossed there shouldn't be much more which can possible go wrong!
Question is, I want to make it to central day! Lol! I have 2 days to put the engine back in the hole! And find a new belt for my dry sump kit, as the belt they sent was too long and too wide! Very very annoying!

Hows this going??
The gtx3076 coupled with a good map will do 550hp anyway,
Nice to see you have gone the dry sump route...
I run a ford racing billet oil pump,
My std pump was fine even when revving to 7500 i just changed it because im going for a +8k rpm limit for top speed test,
