same heads ian? i see you upped the compression............temps still good?

Still running your old heads....I haven't run the car yet but I start testing soon. The compression is up but temps should be O.K as the race fuel runs cooler than pump gas, I believe its 100RON 89MON (max allowed) with 2.7% oxygen. The Sunoco RMR fuel is more expensive than Nitro and my 1300cc does around 7 miles to the gallon.....Better be worth it!!

as you may have seen if you read my post rebuilding the 1679 ,now have some bits from the 1903 but think they may be to much.spec for this rebuild is aftermarket 69 crank(pos crome moly?)balanced with lightened flywheel,stock shot peaned and balanced end for end rods,88 p&bs (slap me if thats wrong )1300 fly cut heads stock valves ,cant remember cam but have a 120 ,cheap old headers and stinger.36idfs on short manafolds.Now on a strict budget so cant afford mega machine work ,plan is to work ports ,check compression and see if it will go 12:1.now the questions,will the web 86c be way to much cam,stock rockers tone it down?or can I fit the 1.4 rockers to the 120.1 5/8 header to big?48idf to big(have some 40s but lots of bits missing )will be happy to run mid 14s stripped out shell,cage so 120hp?starting on it wednesday so any ideas

Dave, remember my old car when it had the 1584 in it?  That was a £100 motor from out of a mates shed, just a stock motor. I added 1.25 rockers, 36drlas on tall manifolds and a 1 5/8" merged header and ran very low 16s. Match ported the manifolds, a new set of stock valves and springs, used the close ratio gearbox for the big motor and it went 15.7's. Don't forget that I'm a decent amount heavier than Holly too, although the car was light.

I'm no expert but I reckon that 12:1 is going to be a bit much. I'd use the 120 cam and no more than 10:1 compression,  and if you can put the 40s together then you stand a fighting chance of getting a 14. What gears are you using now?

[whirligig]

lower 3&4th but cant remember what,we ran just in the 14s as the motor was but it seems to have lost a bit towards the end of last year.will know more when its pulled.

[spanners]

You can't run 1.4s on the 120, it will kill the valve train, pound valve seats and break valves, the 120 will also need double springs to go over 6000 rpm with the 1.25 max r/ratio on it,  and as above, you could run 10.1comp on a 120, but for safety, use shell optimax , for drags the 1"5/8  pipes will work at the cost of low end response,  and yes, the 86c is a big motor, big valve cam, but again, it could work with a very low 1200/1300 r&p and close gears with about a 121 top gear on a 26 " tyre, it needs to scream and will need double springs to rev out to its spec limit.

[whirligig]

as you might have seen from the other post ,had to use the 044 cnc heads so double springs 40mm inlet ect.we ran octaine booster on super unleaded in old motor,it LOVED the booster as its ment to release oxygen----sales pitch dont know but it worked.hope fully will be firing it up on friday,next prob will be jeting it ,took a guess and ordered 138 s old engine ran 130s.have some 150s but will be to big I think.shame cant afford dyno time.

[whirligig]

IT LIVES,fired up motor today and it sounds sharp,did find ign timing over advanced though .reset but not run again yet as fitted drop spindles .test run around carpark (trading estate)tomorrow afty .

[whirligig]

ran at Shakey Sunday,few shake down passes,redid valve clearances and then jet changes.got 2 good runs best of 15.07 so looks well for 14s as engine still tight and jetting not perfect.also ign advance 32deg so might take a bit more.cant work out jetting from plugs as they didnt alter evan when defo to rich! stayed a grey shade?

[fish]

Nicely done for 1679cc 14s around the corner, and probably 13s if you put the car on a diet. what cam/rocker combo did you end up running, never mind I read your other post.

Shaking down my 1300cc Beetle at Silverstone this friday ready for the 2014 Historic Touring Car season, then (weather permitting) i'll be at the Big Bang the following day for some RWYB....I figured its about time someone set an ET and MPH record for a 1300cc....My circuit racing gears are all wrong for the drags (very long first gear, so no point warming the tyres as I have to slip the clutch for the first 60ft)

Still, I won't be happy till i've squeezed a 15 out of it!

You can't miss me...Coral red bug with race numbers pulling 8000rpm!

Good to hear your back out racing ian...good luck...oh and can't wait to hear that 8000rpm,yeehaa.......

[Ian Brown]

Hi....Yes i'm back.

I had issues at the Silverstone 'shakedown' test as the carb base gaskets both had air leaks and I had no spares, plus one of the spark plugs crapped out and I was losing oil which meant I never made it to the drags the following day either, but I guess that's what a shakedown is all about.

Carb gaskets and plugs replaced, oil leak fixed and I'm testing at Brands Hatch this Wednesday (23rd April). In the morning i'll run fast road brake pads using the skinny Historic Racing crossply tyres (120mm front, 135mm rear) then in the afternoon change to race pads with Toyo R888 semi slicks and see what the car can really do. Keep an eye on the Just Kampers YouTube channel for the onboard footage.

Lap of the Brands Hatch GP circuit in a 1300cc Beetle....Bin waiting 5 years to race here again and the alternator belt crapped out after one lap taking the dipstick with it....

[bang]

anyone has some idea for my next engine projekt.

want to build a 1610cc for hill climb.

my engine plan is a dpr 58mm wbx knife edge crank with a flywheel from jussi in finland.
wedgeport heads 94mm 46x36
6,2" pauter alu rods
cp light piston
48 ida with raptor upgrade
raptor cam
dry sump
oxy case

exhaust size i am not shure on.

what do you think of that setup. would it be undrivable

[richie]

An interesting idea


Leave out those rods, all they will do is make you need a real long pushrod, a 5.2 rod would be better

Its going to need to be a real light car for it to work at all, and probably need a 6 speed sequential box like Pete S has to keep it in rpm band

cheers Richie

[whirligig]

not a record but Holly ran a 14.38 @91.5 with a 1.86 60ft .track and air super at shakey on sunday ,a bit to much umidity today

[Ian Brown]

1/4 mile record for a 1300cc Beetle?...If you know of a quicker 1200-1300 let me know.

Also my last 2 races at the Oulton Park Gold Cup (yep...more rain!!)

[spanners]

Yes, short rod motor for the hills, higher piston speed = good cylinder filling, not sure about so short a stroke costing torque tho, it may be a bitch to keep it pulling and Ritchie is bang on about the gears, also I would never knock the fabulous Wasser engine case as I build the beasts, but not for a mini motor on a handling track discipline, too heavy, I would go mag T1 with 8mm studs, weight must be paired all over the car or you are wasting your time, ram air cool it too to save weight, no alternator or fan, oh, and a AA flash light battery too lol.

Oops, left front contact= tyre valve torn out...get some bolt ins Ian, that or short go kart ones.
 

[Ian Brown]

Hi, The tyre was fine, it was the throttle cable getting jammed. I've re-routed the cable and added fresh return springs since.

Next race Brands Indy 28th Sept if you are near by.

That's initial run up to 7000ish rpm only so another 4000 to go!!!   Can't wait to hear it on full song!!

Best to watch it on full screen with the sound turned up to max.....!!

We'll be going back for the JPM Dyno Day to pick it up and have a little test drive   .......flights are cheap!!

[Neil Davies]

Oh my goodness! That is awesome. With the Hewland and the rear suspension, it's really pushing the envelope. It's still going to be a street car tho, isn't it?

Of course.......but it'll take Pete all winter to get the fanshroud to fit....he like's to take his time with the files and hammers.
