View Full Version : u wanted spec on me 1.2 @120mph

u asked for a spec of my 1.2 nova and i wasnt 100% sure but i told u that it beats my m8s 1.8 zetec focous @120bhp and today after stripping the head of as the head gasket had gone i noticed it had 60thou over sized pistons!
i have never known 100% what was done to the car as i brought it from a garage and they didnt know much about it!
so today i decided the only way to find out was to contact the previous owner and ask him!
after many attempts i traced his number and he was verry helpfull!
he said he has had it 1/4mile at santa pod and the quickiest time was 15.1 @ 101mph!
he also had a rolling road print out (not a tune for some reason, just a report) and it was pusshing out 118bhp @ 5200rpm!
he said it is a gas flowed stg2 head which has had endless emounts of skiming to the point that he thought that because the gasket had gone that i would have to replace the head as he didnt think that u could take ne more off! (this was not true because i had it skimmed today and pressure checked and it is now at its max)
he said he had the inlet manofold ported and polished (myself do not recall ever hearing that to have been done before)
lightend and ballenced crank, con rods pistons etc..
ally sump which till now had never noticed or herd of on a nova before but i checked i and has!
peformance coil plugs leads etc...
5 speed box (he had a racing clutch, but removed it b4 i brought it)
thats all he had done!
since i have had the car i have added a 4 branch manafold with full system!
he also said that he alterd the mixture to get it through an m.o.t b4 selling it and retarded it a bit to for a smoother ride to help it sell!
i told him i had a max speed of just over 120mph and he said i wasnt pushing it hard enough as he had it off the clock!
so when its all bk together i will play with the timing a bit more and alter the mixture!
thats bout it m8!
dunno if i gonna burst your bubble here but the guy was talking rubbish. a few examples
in my gte i did 14.9@92mph
in my new shell 14.5@94mph
Now they are pretty much ballpark figures for spec and speed vrs time on the pod
200Bhp @ 6375 Rpm
172Lbft Torque @ 5754 Rpm
1/4 Mile 13.817 @ 103Mph
Thats chris's well specced 2.0 16v and i'm afraid your terminal would never ever ever be within 2mph of that lol. its getting into the same kinda times as 2.0 turbo nova's.
Power wise you are claiming on the limits of a top spec sr/sport with alot more done to it than you are saying.(r/r are also renowned for their inaccuracy let alone just being told something lol) The top speed thing is also a big nono as the speedo's are way out by 100mph without you even dreaming how bad things get beyond that point. You'd be amazed what you are actually doing if you fitted a proper speedo (again it would possibly burst your bubble if a speedo believer)

Do you ever go to Reading cruise mate?
Would be cool to see this car in the flesh..
Has it got the original carb or got twin 40's or 32/34? Thats some impressive figures your putting out, probably not gonna be a lot of people that believe them..

scan the print out mate and put it on here! :)
iv got to see this
I always thought the only way to get a 1.2 to 120 was by dropping it out of an aeroplane, If the mods had been done to a 1.3, then I might believe it, I had a bored out 1.3 and it could do about 115
My Nova only does 105mph...but it gets there fairly quick :wink:

ive had standard 1200 up to 120 a few times.but as u are saying that a 1200 can run same figures as a 2ltr on a quater mile then to be honest thats a bit nuts.if it was a tuned 1600 lump or something like that then its a different story,im not bein rude mate but get theses figures checked out on another r/r session wen u get it re tuned.and if it is true then uve got a proper little beast there in a 1200

my 175+bhp 2lt does the 1/4 mile in 14.5@98mph, i dont see how a 1.2 would have a faster terminal speed than that. Even if it did have about 118bhp i would expect a time of low 16s, around 80mph.
Oh an if you do get a 1.2 up to 120 on the clocks remember that that isnt your real speed

correct :lol:

A4 paper is 11 thou thick, so its a tiddly bit thicker than that?

my 102bhp 1.3 hits the limiter in 4th at 6k and that doing about 114-116.
I worked the speed out using the gear ratio and rpm formula so it is correct.
if i take the limiter to 6.5 k then 120 should be in sight.
if i take the limiter to 6.5 k then 120 should be easy.
bloody hell! i fort fcukednova was just exagerating a little bit!
Now im starting to believe this 1.2 shud do over a ton easy then?

so the 2mm overbore i had on my 1.4 was more than 60thou :lol:

12-12-04, 05:27 PM
i do beleive that 0.5mm is 20 thou ish. so you have 80 thou skim.
Snowface
12-12-04, 08:15 PM
i used this formula:
V(mph) =
n(rpm) x 60 x 3.14 x D(m)
______________________
gr x fdr x 1609
where v is car speed in mph, n is engine speed in rpm, D is wheel diameter in m, gr is gear ratio, fdr is final drive ratio.
works out at about 116mph @6000rpm in 4th.
funnily enough my speedo was reading around that also.
That was on a flat bit of road also. Not down hill.
http://pw1.netcom.com/~sgalaba/mph.htm
or just use that, i have cross referenced it to my own speedo as the speedo is accurate.
good calculator that. but what is the aspect ratio and i dont know the final drive of an f16 box. its not a cr
how many mm is 60 thou? 1.7mm mate, i take it your working out what cc it is
comon luke :( its 1.524mm , 1inch divide by 1000 , times 60 = 60 thou
times 25.4 = 1.524 mm :wink:
and nova speedos are so bad over 100 my old 1.2 engine would do 115 indicated but when i fitted my digi dash it wouldnt go past 98
my 1.4 can only do 116 on my digi

Are most speedos in other cars out, in other vauxhalls such as astras. As someone i know got an indicated 109mph out of a 1.4 astra, dunno if its the true speed though.
How come digidashes are more accurate than analogue needles.

My mate got nicked doing 120 in his Mk3 Asstra... got producer for 90mph :? And i've been in a derv 306 pointing at 65 and got nicked for 58... those could just be the fuzz being a) generous or more likely b) lazy lol
or c) speedo a mile out :wink: :wink: :lol:
oh this is comedy.
mind you id be chuffed with a power figure of 110, but im thinking its not gonna happen at 5200rpm! its going to be more like 6500-7000 rpm.
still if it goes well, then thats all that matters (provided you dont claim some of these figures)
oh and beating a focus ztec cant be that hard as they are fairly low on power and weigh a fooking ton and probably have a gearbox more suited to bimbeling up the motorway, so it wont be fast.
I hired a Focus for a week once and the gearbox was hilarious!
They are WIDE AS FOOK! 70 plus in second, and fifth was a joke, it just slowed down!!!
Nice post btw!

Well the 306 i could understand being as its french... :lol:

most likely to be speedo
in mine i've changed from 1.2i clocks to SR clocks does this affect them? how are they run?

I got 126mph out of a standard 1.2 on the digi dials. dont think that was right somehow. although it was down a very long fairly steep hill. And i think all fords must have wide gears. my escort does just under 60 in second and thats not well into the red. just on the edge.
Snowface
13-12-04, 03:57 PM
going down hill doesn't count!
You could get 120mph out of a Nova with no engine in if you rolled it down a steep enough hill.
Philsutton
13-12-04, 04:03 PM
or let it reach terminal velocity out of a plane
jon_boy
13-12-04, 04:32 PM
LOL just read that back. meant 116 mph not 126.
still 116 is pushing your luck lol
agreed, terminal velocity is the easiest
Funny how this lad hasnt replied since he posted his spec :roll:

ive had just less than 110mph out of my 1.2 - probably around 108mph..i would hope thats pretty close to what i was actually doing, considering the engine mods on my 1.2..
my spedo is bad and its exactly 8mph out. done several tests and at different speeds. still means that my old sr engine got 120 mph lol
my mate got 165mph on the clocks out of his 1.4SR ...
it was on a car park full of ice tho..
was halarious, im suprised it didn't break. still runs stong now (except for the crack in the chassis leg :o
lol. think that would have been the needke just bouncing about a bit
jon_boy
13-12-04, 10:32 PM
well i was kinda pushing it. Ie it wouldnt have gone any faster unless i took it out of gear and something else pushed me. Was a sound little engine though and it loved a good ragging. Felt damn scary to as it was shaking all over the place. Porb doing about a ton or something in real terms.

i had my bros 1.2i pointing at 125mph on the way back from PV
totally std engine
turns out after some calculations on the gearing that it was doing 103mph and that was down a long hill
my 1.4 would get to about 115 on digidash which was about the same when compared with the gearing
my 1.6 16v ive had to 130mph drafting an a4 estate, when i pulled out to overtake it slowed down by a few mph :oops:
so for getting 120mph your gonna need about 85-90bhp
absolute max torque from a 1.2 is ~120lbft (and this would be with LOTS of headwork huge carbs etc) and this normally occurs at around 5500 due to physics and air speeds, any more than this is physically impossible without a turbo
Horsepower = torque * revs/minute * 1/5252
rearanging this would give -> Torque = (HP*5252)/RPM
using your 118bhp at 5200 and this formula that implies your maximum torque value is 119lbft
pretty fucking impressive for a 1.2 tbh, 1lbft away from the theoretical max
lots of the rally engines they build dont even make torque levels that close to the max, hell even SBD's 270kit for the XE which costs you over 6grand only gets 190lbft out of the 20xe which has a theoretical max of 200

lol did you have the switch at the top in the wrong position so that it read double the speed lol :lol: :lol:
or failing that was it in kmh lol

this really is stupid, but i'll join in anyways!!!
My 1L nova did a genuine 101MPH!!! on the flat round the M25!!! i backed off then cause it was screaming its nuts off and the rattling dash scared me!!!

Yeah I had a 1.8 zetec when some barmy woman drove into my car!
It was awesome when compared power wise! alright i do only have a 1.3 but still!! done 0-60 in no time!

14-12-04, 05:08 PM
lol yeah the switch was prob set wrong. but it did feel pretty fast. although maybe it just felt dangerously fast as it seemed like bits might fall off at any second. bit rattly at speed was that car. ah well. doing a ton in the escort feels like nothing now, esp on the motorways.

i've used a handheld gps thingy and all speedos seem to be approximately 4 mph out.
The gps thingy uses signals from 4 different Satellites so i'm guessing its fairly accurate. The guy i borrowed it off had a max speed recorded on it of 500+ mph, he took it on a plane with him when he went abroad.
Firstly my 1989 1.4SR recorded 4 mph slower than i was going.
My girfriends 1.8 2000 Zetec Mondeo also recorded 4 mph slower.
and finally....
A 3 month old Merc Sprinter van was also out by 4 mph.
Government Conspiracy to make us all drive slightly slower???

riggy, just curious here. how come the volt meter on that dash reads near 15v? mine only reads 13v if i'm lucky! did it have a huge battery or summat? failing that, my alternator is fucked :lol:
an to keep it on topic: 120 in 1.2? i managed 95 in mine, 4th gear, foot to the floor, downhill.
Mine reads 15v when its running aswell mate. It reads 12v when i've just got my electrics on. Maybe your alternators abit knackered
snapper
17-12-04, 12:37 AM
hmm. possibly is. had fun a while back driving around with the dash showing 9v :o
that was just before it cut out completely :?
At least this subject has given me some enjoyment on a cold winters eve....
How many times have we been thru this,
some lad claims
'My car can break the land speed record'
and then nobody believes them.
It has been known for someone to rolling road a car, get the printout with reg no., and then swap the engine for some old scrapper, and sell it.
