Altereds / Re: Back on track at last
« on: July 18, 2021, 02:32:19 PM »
Thanks. I don't know what happened with Frantic, I was in the stands at the time, heard an engine rev higher than you expect from the end of the staging lanes, looked over & saw it shoot diagonally through the garage roller shutter door & then seem to stop abruptly inside. I think it was going forward but it was more or less a blur to me. Sad to hear about the Villain, I regret I never saw it run from the stands, only seen it on video I think. I didn't see the incident, we were queuing behind the stand when it happened. Poor Des was strapped in for maybe an hour due to that & a nostalgia F/C oiling the track I think?

Dragstalgia report:
First meeting with solid mounted rear end. Disappointed to find that because there were so many entries overall, our class had only 2 runs Saturday & 2 Sunday.
Friday RWYB only got one pass in, steady checkout that still clocked 8.2 @ 150.
Saturday I leaned out the tune a bit more with some new jets & pills from Good Vibrations.
This really worked, we ran 60' in 1.118, 1/8 in 4.84 @ 145 & 1/4 in 7.585 @ 173 Very pleased as last pb was 7.77. Coverage here at 4:20 in (13:56 on clock).
Tune good, plating just taken off ground straps on most cylinders, couple still rich. I leaned them out a bit.
Next run had some shake as the driver really stamped on it but slowed at the top end, we think this was due to the throttle pedal position. Neil Townson in the other lane sadly lost the body on his beautiful 'Northern Spirit' altered. (8:32 or 18:10 on clock).
Sunday we had the pedal adjusted better, slightly less wing angle & ran 60' in 1.115, 1/8 in 4.83, 1/4 in 7.572 @ 178. Coverage here at 3:52 (13:29 on clock).
Really pleased with that! Good crowd in the stands applauded as we drove past, what a feeling! Des said he forgot to pull the chute before the finish & hit a bump under braking causing the car to bounce badly. We couldn't see anything wrong with it but on the last pass it turned right in front of the guy in the other lane. That was one scary moment but he was quite far behind & got off the throttle to avoid collision. (at 7:02 or 16:39 on clock).
Body & panels off now, going to check for bent/cracked parts.

Hiya, yes we are running Dragstalgia. We've got the motor tuned fairly well considering we're only running an MSD 7AL. Taking 150 or 175 litres of methanol for the 3 days. Luckily I've found a cheap supplier nearby. Suspension is done now & we're really lookin forward to it.

Rigid tubular struts is the conclusion we have come to also. Des the driver is coming over tomorrow so we can start work on fabricating some.

At the end of 2019 we'd had enough of our MSD 10+ not playing ball at start-up. So we fitted a 7AL just to test, it seemed to work. At the end of May 2021 we got back to the track at last. With the motor freshened up by me, some new 6' long wheelie bars also by me, ladder bars dropped a hole & a better wing I was hoping the car would work better. It took me a whole weekend to get the tune leaned enough to burn ok with the 7AL, people were literally telling me it couldn't be done. However the driver said it was much more under control now so I persevered. We ended the weekend with a new PB (just) 7.94 @ 177. Two weeks later we're back to the track with some more jets & pills from Good Vibrations, got the hat/port split better & we ran 7.778 @ 175mph! Well pleased with that. Next job - ditch the coilovers, make the rear solid mounted & lower.

Awesome. I've just watched that & the War Wagon hi speed pass then the 1/8 mile Outlaw Fuel Altered coverage on Living Nitro Youtube. Excellent quality video & sound.

Altereds / Front caliper seals?
« on: March 16, 2021, 02:04:22 AM »
I have just noticed that we have a leak on one of our front brake calipers since it's been stood. The leak is from the centre of the rear, it looks like a narrow part of the piston protrudes and that's where its leaking. The single piston floating calipers came with the car & are probably quite old, I believe they are from Strange. On their website they show a seal kit that fits "all" their single piston calipers (B1260RK) and this is retailed by Summit. Can anyone confirm if this kit should work or where else to look?
I tried to post this twice yesterday with photos but it didnt work so I'm leaving them off for now.

Altereds / Re: What axle oil to use?
« on: March 15, 2021, 03:20:50 AM »
Thanks Alan. I did do some searching a few weeks ago & saw sites stating that the Ford 9" was supposed to have GL6 but GL6 was now an obsolete rating so I was pretty confused. I doubt if there's a spate of broken down Ford axles across the world but they may be wearing faster than they should. I will look for some Torco.

« on: March 14, 2021, 08:02:42 AM »
I'm just putting the 9" rear end back together & thinking about buying some 85w-140 for it. I was wondering what you more experienced folks use, for example is Lucas mineral Heavy Duty ok or should I step up to, say, some Red Line synthetic?

Matt Shaff's Engine Shop / Gear drive runout?
« on: June 07, 2020, 03:53:49 AM »
Hiya, just checking some stuff before re-assembly. Last year we had the cam dowel come out & I found that the hole in the gear drive cam hub was oversize. I removed the cam, drilled the cam hole larger then reamed it & the hub larger, fitted a bigger dowel & it ran ok. I thought I really ought to look at gear backlash & runout while I have time & the motor is fully apart. Rotating the crank & cam with the gear drive bolted down shows no tight spots but the backlash does change a bit during rotation. I removed the cover again to check runout on the cam gear. It's a maximum of 4 thou (or +2 to -2). Anyone know if this is ok?

Thanks for that advice re machining, that's the stuff I just don't know yet. Just referred to my crank figures. After block & caps re-sized & align honed I used King X bearings on them looking for 1 thou and gained a consistent 1.5 thou on all 5 which was actually better. Probably visit machine shop next week, I'd like to know how round the rod bores are too.

Matt Shaff's Engine Shop / Rod bearing clearance
« on: May 23, 2020, 02:39:46 AM »
My local machine shop checked our crank & gave it a very light polish. The guy said the rod journals are at standard. The bearings used by last year's rebuilder were standard (Clevite CB-743HND) and the previous year's builder were one thou thinner (CB-743HXND). The rod manufacturer (MGP) says we need 3 to 3.5 thou clearance. I assumed that when we first got the engine it had been set up loose for traditional thick oil so that seemed ok. Anyway I used fully synth 10w50 the first year & 15w50 last year with no major issues.
This year I ordered King CR 808HPND in standard but before fitting I thought it would be a good idea to check clearances with last year's bearings. I only have Plastigage. Everything was dry & clean & correctly torqued. I was surprised to find clearances were between 1.5 and 2 thou. Now I could use Clevite thinner bearings as above or King equivalent (STDX type) but firstly availability is not so good and secondly 4 of the bearings will still be a little tight at around 2.5 to 2.75. My question is would it be better to have a thou or two taken off the rod journals now then I can use the bearings I bought & not have the same issue next rebuild? I'm planning on using 10w50 oil as the crank is already set for 3 thou.

Matt Shaff's Engine Shop / Re: BBC Main Stud Life?
« on: May 19, 2020, 03:19:38 AM »
Thanks for responses. I got my motor second hand and I have no idea on the history of some of the parts. I don't want to harass the guy I bought it off as it looks like he has terminal cancer, he's got enough to worry about. So it's up to my judgement to decide what to renew at the moment.
My machinist commented the studs looked ok but the nuts were not good. I tried some new nuts on the studs but I think the stud threads are past their best as there are tight spots on them. Seeing as we had fretting on the mains, I think now is a good time for a new set of studs (ARP, what else?). I got a tin of ARPs Ultra Torque lube already. Hopefully they will clamp the caps properly and I will feel a bit less anxious as the car goes into stage!
