Holden 186 top speed?

[Goosey]

Just out of curiosity as mine still won't be on the road for a while, what would be the top speed of a 186 Holden motor in a 1974 Series III with 4 speed box? I was just curious to wether it could get to 110km/h on the Highway? Also the head was replaced not too long ago (maybe around 10000km's?? Not too sure)

Four and a half thousand revs in 4th gear will give you about 120 kmh....but thats a lot of noise.

Cheers, Mick.

Cheers Mick!

Cheers, Mick.And a lot of shakes, rattles and rolls and if and emergency stop is required you'll need about 3 1/2 aircraft carrier lengths to come to a halt.

And a rapidly descending fuel gauge! I wonder how long a 186 will last running at that speed? There is a good reason why a large proportion of Holden conversions had overdrives.

pftt....


just use a crumple zone, that'll pull you up a lot faster.

Just out of curiosity ---- what would be the top speed of a 186 Holden motor in a 1974 Series III with 4 speed box?

At 110 Klm/Hr you getting close to the top speed of a Holden powered Land Rover, which is directly proportional to the thickness of the ear protection you are wearing. :spudnikheadphones:

At 110 Klm/Hr you are getting close to be selected for the next James Bond movie, to be used as an extra to lay smoke screens! :D

At 110 Klm/Hr you need to be following a semi to pull up, the semi has a slightly longer braking distance. :eek:

At 110 Klm/Hr you need to wear a freezer suit, to keep the heat out. :twisted:

At 110 Klm/Hr you need to watch very carefully for speed camera's, in 100 Klm zones! :nazilock:

At 110 Klm/Hr , how do I know all this? :angel:

Yeh and you will probally buckle the steering wheel because you will be standing that hard on the brake peddle!

Hi there

It can be sumed up in an easy phrase:

........With ear muffs on your gearbox & axels are your limits......


My views

[Kime]

Meh, u all make jokes about the distance it takes to stop..... Unfortunately it's all true :Rolling:

My ol s3 had 202 red, with overdrive, 30 x 10.5's, 3.55 diff, and top speed I got was 140klm/hr... And a whole heap of grey hairs too :wheelchair:

My current s3 wagon with red 202, 4spd no overdrive, same tyres, same diff I got the other day 120klm/hr.... And I think I would of lasted maybe 5 mins, not sure whether I would of run out of fuel first or if the engine would of overheated....

Just put a mild cam and a set of twin strombergs on it with electronic ignition and some mild head work and extractors a Holden 186 will scream all day and still live to see tomorrow. Fuel economy well if your worried about that why did you buy a Landrover

[akelly]

I've had my IIA 88 up to 140, but that was in OD and a slight downhill, and a very long straight...

Was a bit of a moment, for us both! I don't do that anymore. We stick to 110 now.

If I stood on the brake pedal at 110 I'd do a front-flip! Maybe you lot need to adjust your brakes...

:wasntme:

[Bigbjorn]

My Showroom Stock EH149 road race sedan would pull 6200 rpm no problems.

You must have a PBR power brake sticker on the back window:angel:

Many years ago I had a 186 with all of that fruit (except I used a 2 barrel carb from a 253) in a Series 3 SWB. Down a long hill on the Hume, at 80mph with no overdrive, there's that much s... going on all at once that it's beyond description :D. I reckon I could have coaxed a bit more out of her but the doortops were flapping that hard I had to ease off. :p

Cheers,
Anthony.

If you want to drop the revs (or up the speed) you could always fit classic rangie diff centres 3.5 instead of the standard 4.7s ;) If youve got a shorty Or stage 1 diffs for LWB

Good way to throw a rod/ break a piston crown in a 202:o.

A balanced 186 with decent cam, headwork and carburation will easily see 6000rpm. The vehicle and the operator are the limiting factors here:cool:

Refer post no.13. A 149 with single Stromberg, standard manifolds, only head modifications permitted were by removing metal. Creative engineering from the Smoky Yunick School of Rule Book Compliance. Pulled 5600 rpm in top down the straight at Lowood. Would run to 6200 rpm in 1 & 2. Dead set "Showroom Stock" and no scrutineer ever managed to find otherwise. Used a diff centre from a Bedford ute. I forget the ratio, may have been 4.11. This was not kosher but was never found. Other than the diff. ratio, there was nothing done that the rule book forbade, unlike others. Cheating was rife in this class.

Aftermarket forged pistons, Starfire/ blue motor rods. Blue motor counterbalanced crank modified to fit the red block. 7500 rpm a la HDT Toranas.

[justinc]

...i was talking stocker red engine 202, not many series owners can afford to build a decent 7500rpm donk...:(

I've got a little 192 in the shed that pulls to 8000 rpm. Although engine builder ( ex HDT) says it only needs to goto 6000. Most engine builders only like to rev 202's to about 5800

[rick130]

All the old rally 202's from the seventies/eighties would easily run 7200RPM all day (and season) long.
The extra torque from the 202 is a big advantage when racing/rallying.

The current race 202's as used in historic racing are insane, running roller cams, etc.

Starfire rods, blue crank and decent pistons help a lot without going OTT. :D

When my uncle built his 186/192 for his Series III (wish I'd bought it off him :() he just balanced everything and carefully assembled it, probably no-where to the degree I would have done and with the overdrive it was silly fast, but then it was a quick car with the old 2.25 engine too with a set of Perry headers and a decent exhaust.

When I was a kid Dad had a near new and very well running HX or HZ Holden van sans all the ADR27a stuff :angel: sitting at 140km/h indicated and the Series III with the 2.25l engine pulled away from us on the freeway near Goulburn one night :o

[edit] oops, Brian already mentioned the rod/crank combo

[omnibus]

the truck in my avatar was a 202 yella terra head, cam, carbs etc i had a small test with a member of the boys in blue and at a servo we disscussed how fast the old rig could go,(usual comments like 95 down hill with a tail wind) as he had owned a cpl, well he suggested a test on our way home so he sat behind me and speed checked me on the highway, the result was very cool, A DEFINATE 100 MILE PER HOUR + a cpl
it was awesome only problem was keeping gearboxes to it, it loved eating them .......

[landrover dave]

You should be able to get about 70-75mph out of a stock red motor in a shorty, knock about 5mph off for a 109. Put a high speed transfer case in and you will see around 90mph in a 109!

[Series3 GT]

The only other thing you'll have to get if you want to go 90MPH in a 109, a large supply of new underwear.

Not quite, if your running the std rag cam gear. I came unstuck after overtaking up a hill doing about 115-120km/h... :o I completed the passing maneuver only to be left with no power and a long tow to where we were heading. Changing a broken cam gear in the bush is not much fun.
