is your saphire honestly putting out 900bhp or am i just gullible
why dont you get a specialist engineer to make 1 up from hardnd steel it might be expensive but so would buying new ones all the time, just an idea

We have no figs set in stone but you can work it out, 1000cc Injectors @3.5 bar +2.5bar boost so 6bar fuel pressure @8k 100% injector duty and we had to use the NOS fuel jets to add fuel I think it was 120 fuel jets which was double what we ran before.
So we can guess at 900hp and it is beliveable even for a scinic like me on HP est

That is truely amazing Rod

And big respect for what you have already done, and if you can build it up again, and beat the record again, then that's just a bonus


I hope in the long run it is worth it for you to carry on with this

this millington block cracking issue is new to me also i know someone running over 700hp on one of these so being rated at 400hp may be a little conservative eh!!

There is no way on this earth that the crank is 100 % perfect and i for one would not reuse it in your engine running such torque induced by the Nitrous !
I may be wrong though
Thats you opinion its not mine and thats what counts

The block should have been dressed right not to have any stress risers

You cant see correctly what has been done and what has not

I suppose your right its Rods money after all
I suppose he will have to foot the bill when a sudden vibration turns into catastrofic failure
I just hope the flywheel stays where its suposed to
But then again im probably wrong
Yes your right you will be wrong

Good luck with the rebuild Rod
At least you have more that achieved your goals
It was enevitable that some thing was going to let go in the engine
with that amount of Nos on top of what you allready have.
It may be an omen !
I dont think anyone will get that kind of topspeed for a long while anyway.

how many hours has it run @ 700bhp+ ?
2litre vauxhall methanol dragsters 1200bhp+ so i don't think the power wrecked the block!
why didn't you use methanol to achieve huge power ?
.
personally i think you/mark have pushed the boundry enough! and a credit to you both ,but it is risky business imo, you/mark want to be known for being the fastest not remembered for being the fastest if the worst was to ever happen. soppy old crap i know

What i want to know is why on EARTH did you put the new NOS system on or what ever you was told to do ....your failure was listening to someone else and not sticking to your own abilitys IMO.

The engine let go because it was pushed too hard because of the new NOS system...it found the limit of the YB and it was NOT a MAD idea...it blew because of outside influences...just keeping it real YUM.

Instead of taling in a cryptic fashion why dont you just say what you mean Phil. Anyone who has been keeping up with Rods progress knows what you are trying to imply: Chip has an input into the nos system and that why it blew is the message you are trying to get across isnt it which i think it bollocks. No way would Mark have anything on that engine that wasnt 100% ok.

Rod,

Shame to see the engine come to such an end. Considering the extra stroke and 8,000rpm the piston speed would have been similar to a non stroke cossie revving to 9,000rpm let alone the massive Cyl pressure.

For the new engine it may be an idea to look into alloy con rods and an alloy flywheel to help reduce the rotating assembly/mass. At any given rpm, having a lighter rotating assembly will make life easier on the main caps/studs as the load on the main caps/block will be influenced by the rpm and the mass of the rotating assembly.

The only down fall for the alloy rods would be that they do have a “life expectancy” meaning that they would have to be changed every XXXXX miles of usage as well as the fact that you would have to compensate for “rod stretch” at high rpm's so inturn allow more clearance between the piston crown to Cyl head face.

Best of luck on the new build

Jake

i have to say fair play for fooking a YB block like no one else ever has true performance.

looks to me like it may ( and this is obv only from a few pics) have simply pushed the bottom of the block away with sheer piston force on the ignition(power) stroke, many ways to prevent this if thats what happened, couldnt be so sure without seeing it

this is what happens to development engines, im sure it was expected at some point guys.
