Boosted Falcon

Ill start with this...

Specs: Eb fairmont, 6into1 turbo manifold, 70mm turbo, bbm intake, 60lb injectors, el ecu with j3, 1x 044 pump inline being fed from stock intank pump, stock btr auto etc.

This is piston no.1 removed from the stock eb bottom end.



Suspected cause is a massive leanout due to dropping fuel pressure under boost. Fuel pressure dropped to 40psi under 20psi boost. I have another stock el motor just about ready to go in. Planned upgrades to prevent this happening again are surge tank with 2x 044s, plenum for better air distribution and care with tuning.

To be honest this motor would still be running if we stopped as soon as it was obvious it was too lean but it had been oiling up no5 plug for ages and i suspected a busted ring land. On inspection no5 piston was fine must have just been the old 236000km rings giving up slowly.

shit man! thats decent!

Haha yes it had some blowby.

Geez, i farked up loaded 2 threads the same can someone delete the other one?

T5 third





Driven by a mildly modded 4L, after smashing into third doing fucknose how many laps of Willowbank.

Not enough power for the cushioned button to slip; the Kaaz wasn't going to break; and not enough power shear the input shaft or break unis or axles or anything. Just almost flat-shifting at 5-8 into third repeatedly with a harsh clutch not made for a standard box.

Lesson: Buttons are shit. Organic until you can afford a twin-plate.

sounded epic on the drive home =D

I win haha.

Too much timing for the boost, compression and rods I was running.

Not quite Josh........ This is the result a mate had from a rod letting go in his BF1 XR6T

I wish mine burnt to the ground, I would have gotten insurance money.

Haha I was waiting for that!!!

sump bits down the bottom, rod bits in the middle, piston bits at the top lol
AU engine, overboost and lean out = bang

I see the piston from the oil pump pressure relief over to the right.
So what broke, cyls 1 and 2, or 2 and 3?

yeah i was wondering wtf that was
piston/rod number 1 and 2 let go and bounced around in the sump for all of 2 seconds and this was the outcome lol
the oil pump and pickup obviously died also.
