Butcha

Fyi The rigs still goin last meet i fucked up with some ecu parameters and after 2 laps engine went off song and was huffing oil out the dipstick...fuck. got home and i found i blew the head gasket on 2,3,5,6 and blew a hole from the chamer on number 6 though to the pushrod hole. Coating the pushrod in molten alluminium.
 
Assembled the spare head i had here with the valvetrain and shes back up and running for tomorrow night. Had bit of a play today with the tuning and it feels good. Ripped 100m skid in 3rd on the road @7000rpm and she feels good so we will see how we go tommora night.
 
I will say the turbo feels lazy as i am down from 12:1 compression down to about 10:1. Though it should give me a wider tuning window.

20 min run time for the cam coupla revs in the shed..grand parade then off to 6k full race. Never babied a new engine just run the cam and vary the load. Quicker you bed rings the better.

Crank it back the other way.

Can't helicoil that bastard, grout the shit outta it n put it back in?

Nah mate traction suffers - especially if you have good hp.  Lucky the carton motor didn't suffer from that so what it had, it got to the ground.
 
Brenton copped a good tap on the right rear corner after he passed Dave Stretton - who was driving Max's car (5).  Dave was loose and rusty as and turned into Brenton.  Nothing intentional I don't think - just a case of old rusty driver in a car with plenty of stick. 

The turbos first full power run. I started on pole (1st). Flames not big enough me recons.

Yeah this happened..





Which resulted in..


Have stripped her down to give her a bath. Everthing looks good no scuff marks or otherwise. Need to find the older style gaskets, at least they dont put graphite shit through the engine.

What head studs do i need to get? Dont think head bolts are gonna cut it.

Using lucas oil 20w50 full synthetic race oil at the moment. Hows that pm50 go with meth? Is it synthetic.
 
Didnt seem to get much done today, i got an argon bottle and had a play with the tig. Fun stuff. Welded on som -10 fittings to the valve cover and made up a sheild to cover the turbo a bit.
 

 
Shit seems to drag on sometimes hopfully get the bulk of it done tomorrow.

Not sure abou half moon deal? I jus us 75ft never popped a gasket up tat way?. Always round 4-6 that goes.
 
Thought about running braided hose front to rear but 500 bucks just for hose cuts into me beer fund a fair bit.

Cheers rob managed to get both. Engine has been stripped and re-assembled. It looks like the top rings have lost a bit of tension but should be right.
 
I might measure the injector deadtime while i have access in the engine bay.
 
Just have to fab an alluminium sheild with some standoffs welded on the ex manifold to cover the turbo while the engine is on the stand then back in the hole again.

Good work butch - saw the fire photos on Gordong.com and wondered what was going on.  I have missed both race meetings this year thanks to other commitments but I should be at the next one. 
 
Young Brenton had the corty firing by all accounts, getting a heat win and finishing 2nd in the feature.  not bad for a $600 x-flow.  Long love the crossflow mate. 
 
I'll see you at the next show. 

Nice try Butcha, but don't think the cam budget will go that far.

Hey haven't updated this for awhile bit rude I Know. Had the first race with the engine last night with mixed results.

First heat It was running way too lean for my liking so I just had a play passed a few people then backed off for a bit and went again from 10th I finished 5th or around there. Second heat fattened up the fuel table and started the car to grid up and it stalled straight up battery shit itself, in the process it messed up the ecu and was not detecting spark so had to wind some pots back and forth, swapped the battery out and she fired up ok for the 3rd heat.

3rd heat Started P1 finished p1. Woo this thing had some kick!! The valve cover gasket blew out the side causing a little smoke towards the end and caused a fire when I pull up in the pits. turbo Housing was glowing cherry red. Pushed the gasket back in and did a few minor things to the car and went out of the feature P4. I got a reasonable start passed P2 and started to chase down the leader but on the 3rd lap a bright red glow came from the bonnet... the turbo oil feed line (brand new double braided line) ruptured for no damn reason causing a nice big fire. No major damage just white shit everywhere from extinguisher.

Have attached a screenshot of the datalogs from the start of the 3rd heat about 3 or 4 laps worth. Its still way to lean at the part throttle bits but thats easy fixed.

Things i need to sort before next meet
- oil temps are hitting 280+ need to put oil cooler cooler in to bring them down a bit
- Coolant temps are a bit high, richening it up a bit should help. bringin oil temp down should help more
- Need a bigger alternator, its keeping a satisfactory charge but not at High RPM el/ef 100amper should do it, slow it down a bit wont hurt.
- Need to stop this freakin valvecover gasket blowing out on the right side.
- Fatten the tune a bit more.
- cool the intake temps down a bit 111 sounds bit high. A jet squirtin methanol/water into the intake should suffice.

Other considerations
-I need to drop my diff ratio down a bit I am running out of legs down the straight and its hurting my corner entry speed a bit. By legs i mean the shift light is blinding me and im lifting the pedal (6500rpm set 7000rpm fuel cut). It by no means runs out of power there.
-Seems the 44mm waste gate isnt big enough as it is set on its minimum setting of 8psi yet it gets up to 14 psi before things get hot. not complaining though

Other than that I'm happy as pig in shit on how it went on its first night out


 

maybe reg or power supply to pumps when loaded - electricity - me no deal with it - can't see it and it will kill you.  Best get that sorted before we hit the rollers. 

Manage to ream the seat of regulator and got it to seal. A bit of shit musta got into me fuel gauge cuz it read 0 pressure even though the car started. I cleaned it out and fuel system is sweet now.

Starts and runs sweet even though it is rich as shit. Methanol is awesome like that.

Heres A shitty video for your viewing pleasure. The yellow line if you can barely make out is afr.


 
its pretty cool though as you lean out the cells and bring it close to stoich it cleans up a bit and picks up a coupla hundred rpm.

Now gotta get this puppy onto a dyno or track to tune her up a bit.

Just pulled reg out n bench tested an shes stuffed the return doesnt seal as meth has eaten the sealing surface.
 
No it is a standalone ecu.
