power in 5th gear

[Big mcd]

Hi everyone just wondering what the acceleration should be like in 5th gear,if i change gear at 7500 from 4th to 5th it seams to die,it doesn't go slower but it doesn't accelerate much either.Oh its a 182 cup

 

[edde]

7.5k? Engine red lines stock at 7.25k.

Its not going to fly in 5th gear at those speeds though. (unless its one of those rare engines which few people has).

 

[16v_jon]

7ish rpm in 4th will mean 110-120 1x7's run out of puff at 120 ish

 

[Big mcd]

It might be a less than 7500 cant really tell its about the time the change light comes on it is showing about 110 on the speedo.I thought it did 140ish it would take the whole of the m6 to get to that at the rate of acceleration

 

[-Leigh-]

I can get to 120 relatively easy, but after that it takes a while to make it go faster. It will do it, but it takes a while, and in the time your waiting, normally think 'I should slow down' lol.

 

[black kro]

without a BIG engine or decent turbo you ain't gonna get much out of anything changing up @ over a ton!

 

[Nez]

Mine picks up in 5th just after 110mph.. takes me to 130 easy after that..

 

[Dan@SJM]

my 172 used to pull cleanly to the limiter in 5th

 

[RacerStu]

^^ Mine does too

 

[Moz168]

Some of us only dream of doing a ton I did get 90 though...downhill, with the wind behind me.

 

[Dan@SJM]

Infact my valver pulls to the limiter in 4th, 140mph, then still pulls in 5th but runs out at 155!

 

[AlexS]

My 1.2 16v does a ton in 4th then pulls cleanly to 110 in 5th and if you take a few weeks off work it stops at about 116. Maximum recorded speed is 106 on the garmin though!

 

[GordonD]

That would require 250 bhp.

So there are two alternative possibilities. One is whether you should believe your speedo. The other is whether we should believe you.

 

[Peperami]

Mine pulls cleanly all the way up to 135. The last 5mph after that takes a while.

 

[Justin182]

Its funny how fast the pace dies down after 110mph, considering how fast it gets to 100. I think mine is pretty quick to 130 even, although in the vid below, when doing 110... it was actually up hill a wee bit.

Exactly the same as my 1.4 8v! Wish I had an extra 8v! Change into 5th at 90 but never normally goes past 110. I've stopped trying now though.....*runs to car to go and try.....runs back in....not worth congestion and driving ban*

 

[S22 JGS]

lol i thnk you should all do a bit of editing before you find a letter from the cops in the post

 

[Justin182]

lol..... but obviously were all talking about the autobahn and track of course.

 

[Big mcd]

talking to a 172 owner today his will reve to the limiter in 5th,is the gearing differant on a 182?

 

[nathanH]

my 172 used to pull cleanly to the limiter in 5th

mine too

 

[DrR]

never been past 120 in mine sadly, got there no problems in 5th though

 

[KrissyBufton]

i dont think mine pulls that cleanly to 100... it took around 18secs by looks of it, and following the clock of the video, but seems to struggle more than Justins at around 80mph... but bare in mind mine doesnt have any of the mods Justin has apart from panel filter.

got a vid of mine...

[-Leigh-]

Funnily enough, I got a video on the way home on a dual-way airfield.

times are about

6.5 to 60
10 to 80
18/19 to 100

which is about right for a standard 172 I think.

 

[KrissyBufton]

my vid doesnt seem to work... heres a diff link to it

Yeah, ive got remap, sports cat and exhaust, oh and a matched inlet so maybe why i pull a bit better at higher speed. My blowing exhuast prob doesnt really make a diff the performance as its only slight.

Seems a good pace for a std 182 though mate !

I think in my vid i was changing a little bit later then you. 63 - 92 and 110 which might have put me in the power more for the next gear.

I made your 0-100 in around 16 secs which is what i would expect from a healthy std 182.

 

[KrissyBufton]

yeh i get abit scared taking it too far thru the revs, it sounds like its crying thru pain just before the limiter hhaha

does it seem like a good pace for standard tho? im never sure if it was quick enough or not haha

 

[Justin182]

Yeah, seem exactly what i would expect, using the timer on the vid.

0-60 i think was between 6-7 sec and 100 in 16 sec.

Remember it takes a whole second to past before you count the 1st second lol.... sometimes catches me out lol

You just need longer Autobahns.
125 indictead which was 113 on the GPS is my best ever with 65hp.

And that realy was in Germany.

 

[Fred@BTM]

we've had just over 160 on the clock of the cup LOL

 

[GordonD]

my 172 used to pull cleanly to the limiter in 5th

mine too

7200 rpm?

That would require 235 bhp.

 

[psycho]

Me and the other 182cups that come to the local track days get up to about 170kph (~100-105mph) in 4th down the straight. Maybe our speedos are flattering us but its still pulling quite nice at that speed.

 

[Dan@SJM]

Infact my valver pulls to the limiter in 4th, 140mph, then still pulls in 5th but runs out at 155!

That would require 250 bhp.

So there are two alternative possibilities. One is whether you should believe your speedo. The other is whether we should believe you.

The speedo isnt that far out, 1mph at 30.

But the box ive got in there means im at 6k at 155.

 

[Dan@SJM]

mine too

7200 rpm?

That would require 235 bhp.

lol @ you and your 'theory'

i suppose my mates 1.5 almera that is only 90bhp stock wont pull past 100? when it'll do 120 on gps.

 

[Steve2004]

Now that's funny! (my mum used to have one of those 1.5 90ps almeras). Only way it'll do 120 is by driving it off the top of a large mountain :clown: .

You must have a very special valver to do 155 on the clocks lol

Unless a diesel box gives you an extra 70 bhp ...:clown:

And an extra 800 TORQUES.

I don't know what the drag figures are for an Almera.

But if you put a 90 bhp engine in a Clio Sport it should do 110 mph.

You've somehow succeeded in producing enough power from a 1.8 litre (?) engine at only 6000 rpm to pull the car through the air at 155 mph.

Congratulations. That's an unbelievable achievement.

 

[MarkCup]

I agree with Gordon.

It (almost) doesn't matter what your gearing is - to get a Clio sized/shaped car to do 155 mph needs 240-250 bhp.

That's based on 172 bhp getting a Clio to 138 mph as a starting point - the wind resistance that needs to be overcome going from 138 to 155 mph consumes an extra 70-80 bhp.

 

[Fred@BTM]

what mark said 160 on the clock down bruntingthorpe i would estimate at 150ish

i've had 153 on gps out of the V6 down bruntingthorpe (bookfigure) that was showing just over 160 on the clock
