Blackbird reliability
A friend of mine was considering building his next car with a blackbird engine.
This is the second time the
MK car has had reliability issues (the other at brands hatch) with a blown engine, are BEC's that unreliable?

Nothing wrong with the Blackbird engine. Jon Ison has had years of use from his (corectly mounted in a GT1) and under very arduous conditions. There
are other's who run them regularly in 7's with dry sumps. They are fine with dry sumps but have an oil starvation problem if driven hard
on track or race without a modified sump and baffling.
Research on BEC's shows that basically there are favourites. The Fireblade still is out in front for reliabiity but R1's, ZX9R's and
other's are increasing in popularity.

As Hellfire says above the blackbird engine is very reliable when dry sumped. You realy do need a dry sump though. I learnt this the hard way by
knocking out a big end when I just had a baffled sump but I rebuilt it with a dry sump and havnt had a problem since even with the amount of abuse
(nitrous) that I give it.

I have since found out from baz after stripping the engine and putting in an new 1 that the oil cooler was blocked with sludge, looks like the reason
for the first engine blowwing as well as did not clean this out properly after the first engine blow.
bear this in mind maybe a good idea to upgrade the oil cooler ??????.
had no probs with mine on the road but will do the mods before i take on track.
anyone have reccomendations for a zx12r as my brother gets his car soon ? should he use a baffled sump or are they ok without??????

I know a guy who did a full trackday in a ZX12R and lots of fast road driving without a baffled or chopped sump and he never had any problems
whatsoever.
Personally, I think that a baffled sump should be fitted at least for trackdays and also piece of mind. A full dry sump would be better but still has
no guarantees. I know a few people who have blown their ZX12R's with dry sumps fitted.
At the end of the day, its a gamble that you take. The decision, is yours. Or in this case your brothers BTW, when is he picking it up? Does
he have a firm date yet?

Hi Sean,
yeah, we have a power commander on the ZX12R with a custom map installed by Holeshot Racing. It's definitely worth it  Keep an eye out on
e-bay for one, they can usually be picked up cheaply.
The sump we have on ours was modified and baffled by Z-cars.

Cheers for that helfire ill get him to look into this.
to get back to the original quote on blackbirds i got of the phone to a friend of mie who has just soldhis dax rush bussa turbo b holeshot and he ran
a standard sump with no mods only a upratedoil cooler and had no probs with 380BHP on tap and he was a serious racer.
to also note he would run with 10 % more oil in to cope with the g force.
this was in the top 5 cars in the track and race car mag around the circuit. so could answers some issues on this long debated topic??????????
