If you type in 977ARX on google u'll get loads about it, its a genuine ex-works rally car from the 60's i believe.

Anyways, saw Pete today, i forgot to take a photo as i was kinda a bit gobsmacked... it looked something like this (see shoddy diagram).. No word of a lie, a perfectly straight line from 3000rpm (didn't notice the power figure) up to 105bhp at 7000rpm. But what was just as impressive was the torque curve, 70ft/lbs from 3000 rpm up to roughly just over 80ft/lbs available from 5000.



well happy can't wait even more now, just 2 weeks left

3.9, so yea, more torque gets to the wheels and it should make it all a bit free-er and smoother. Went for the 3.9 (3.6 +1.08 ratio droppers) over the 4.1 because i'm thinkin the much improved power and torque of this engine would just rinse a 4.1. The main reason tho was for more suitable gearing. I could theoretically with the clubman gear ratios, get over 70 in second gear but also 60 at 7000rpm, with the 3.9 now. Unfortunately because of the 1:1 ratio i dont actually drop many rpms in 4th compared to the 4.1, probly only a couple of hundred rpm (it use to be 5000)

Straight cut drops at 5000rpm down the motorway, woop! should be fun

Teaser  

bungle - yea preferably - mite work a bit better ... however nt too sure how effective it would be just yet seein as there is nothing inside it.

Keen eye'd will notice the lack of a crank and timing gear.... I picked up the block and gear casing from bromsgrove engine services today (many thanks to them they do top work, and was even went in on a saturday so i could pick it up early ) I just put the block on top of the casing to make it look pretty

mini 93 - uni's over finally! Lots of progress soon.. tho starting tomorrow i will be in the garage pretty much all day solid, so will only be on t'interweb briefly... not like at uni when im logged on pretty much all day even when im out it stays on

Gotta repair the blasted radius arm pins first, for MOT, then the engine will go together very quickly

Still waiting for the hardened layshafts to come into stock at minispares, and gotta get the bits off dogmatix that he owe me... that chap has a memory like a sieve Then i'll ave everythin

woop woop

Funny u should say that, i'm breakin it out tomorrow for 'adjustment' to the inside of the block...

Anyways, progress is guuud ent got any pics tho i'm affraid because i've been to busy

Sunday i spent repairing the radius arms, i managed to do them both in a day which was good. So with that out the way i started the engine on Monday afternoon by putting the head back together. Today i've done a test build of the block, to check all the clearances and stuff. So basically built up the whole thing as i would normally, timed the cam in, then put the head on with rockers to check to make sure i'm not gonna have trouble with exhausts valves hitting pistons, following a conversation i had with nick swift yesterday. I called him up for the timing figures for his cam, and he mentioned that i should check the clearance because of the small chamber size then get back to him with the figures... very helpful chap He said that 60thou is the absolute minimum and i've measured 90 without a head gasket (which is another 30thou) so i should be okay, woop!

Also while doing this i found the last cam lobe on the oil pump end is fouling the block casting where theres a little lump of metal left, so the dremels coming out 2morrow before i re-build it

After doin the block, i started the stripping the old mainshaft of 2nd and 3rd, thinking that i'd build the box up tomorrow, turns out it didn't take very long at all and the whole box is now finished more or less. Had to measure up the gaps of various shims that i'm gonna see if i can get from the engineers tomorrow.

I did make a massive schoolboy error, forgetting that the transfercase from the 1071 was pre-A+ with the smaller idler bearing, and my drops and gearbox are A+, which means tomorrow i've got to take one of the 998's transfer cases to the engineers to get it steam cleaned and pop the old bearings out

All in all its goin well and i anticipate that the motor will be nearly finished by tomorrow and in and fired up by the end of the week. Unfortunately tho, theres a few small bits do do for MOT that i dont think im gonna get done in time for an MOT on friday, so i'm gonna have to wait till after christmas

Nite y'all

Well, after even after months preparing, trying to get everything ready so you can build you motor quickly and swiftly, i can promise you its not gonna happen. I took the short block apart after doing the dry build to grind the bit away and thats finally coming together nicely tho now, after sorting the correct size thrusters, whey! I think the main problem building stuff like engines and gearboxes in your garage is the lack of spares... namely shims and thrust washers to give you correct endfloats and clearances. Since being back from uni on friday i have been to the engineers on saturday, monday, wednesday, today, and i will be going again tomorrow!

Tomorrows the last chance because after tomorrow they're closed till january 3rd.

I gotta go again tomorrow so they can sort my baulk rings.. see here.. http://www.theminifo...x...c=66760&hl=

So gearbox has gotta come apart again woop... another set back

Nevermind, i'm not really in too much of a rush anymore, since the RR/MOT place aint gonna be open now for a week. Just hope i dont need any more bits from the engineers

Soz for the lack of piccys, theres not much to see to be perfectly honest all looks best when its all together.... so i took these





By the way, thanks to whoever put the 5star thingy on my project, i've no idea how you did it (unless its a moderator thing?), but i appreciate it thankyou
