[Dansta]

[Cuppy 172]

Should be looking at over 100 mate, your car is fcuked

 

[Roamer]

Over 100mph? in 3rd in a standard ecu cup? nope - 86/87 max

Whats rpm is it limiting at? 7250?

Thats 4th

 

[Roamer]

in 4th you should be getting about 112/115 iirc

 

[Cuppy 172]

Sorry, its been a long day, 90mph just been out & tested

Not on your life...

The Cup (or mk2 172) will do 89.9mph @ 7250rpm limiter in 3rd gear, no matter how much power it has!

 

[Roamer]

soz about being a few mph out, its ages since Ive driven a 172 with a standard ecu - actually its a long time since Ive really driven a 172 at all lol

 

[Dansta]

like i said...90mph

 

[Klang1.6]

IF I CAN ONLY GET 80 WHAT CUD BE WRONG

 

[Roamer]

What rpm is it limiting at Klang1.6??????

 

[Klang1.6]

i check on mi way home

Well is it revving all the way round to 7250rpm or is the limiter cutting in early???

Just that 80mph in 3rd is at 6500rpm which is when the limiter kicks in if the car is not fully warmed up, so I reckon thats your problem!

 

[spirez]

i got 90 i my old RT!!

 

[swelch]

90mph

 

[Neil82]

98/99 mph @ 7800 rpm..... 88 ish standard.

 

[Jon1978]

I think that the good Cup/ bad Cup debate is about to start again.

I have done the suggested run-in period of 625miles in my 53plate Cup, and since then have stretched her legs a bit, and I can get well over 90 in third gear.

 

[CUPPY]

same her mate over 90mph indicated!!! but then again my engine is f**ked.i think...oh b****cks!!!

 

[wackojacko]

Yeah but remeber fokes 90 indicated on the speedo, aint actually 90 is it!!

Not really...

They all have the same gear ratios and (unless modded) they also have the same rev limit, so you can only go so fast in each gear no matter how much power you have!

Dont forget that there is always (no matter how small) an element of speedo error and this can (& does) vary between cars, so what you see as an "indicated" 90mph in your car may not actually be a "real" 90mph and its only going to go as fast as the revs/gearing will allow...

On the q_mile a pod I was just changing into 4th at 89mph just a few yards from the finish and mine R-lines at 6800

 

[Chris n nic]

Im in the same boat. just have to change b4 the end...but at about 95mph

Pete, I know you said your redline marks on the rev counter were lower than on my Cup when we were at pod, but does it not still rev to 7250rpm?!

Same with me Chris, I thought with the higher limit I would be able to cross the line in third but you have to still change into 4th near the line.

 

[JAY172]

about 90 at max revs

 

[Frosty]

Firstly, are you letting your car warm up enough before you do it? Most people here will tell you that the car is limited to 6750 rpm (from memory) until the engine oil reaches a safe temperature. After this point you have the use of 7250 rpm.

If your car only does 80 mph in 3rd gear, but still revs right round to 7250 rpm then 1 of two things is wrong.

1) Your speedo is wildy inaccurate and probably illegal with such a huge margin of error.

2) Your final drive ratio has somehow been altered.

In both cases you need to speak to your dealer, although showing your dealer a problem that occurs above the speed limit is something of a gray area.

My old mk1 v6 chipped would do 90 in third,so i find it hard to believe that the 172 and cup doed this aswell,cheers

 

[derv]

ah, the v6 has 6 gears though, so the ratios will be different, i could get 85 mph in my 1.0 litre micra in third but it only had 4 gears!

 

[Chris n nic]

It does tho m8....std about 90mph.

Its true mate, and the mk1 can go marginally faster in gear due to longer gearing...

The V6 has closer ratios being a 6-speed box, so cant go as fast in gear and I know a CTR wont hit 60mph in 2nd gear as another example of close 6-speed gearing. However, this aint true of all 6-speed cars and my old 306 Rallye would do almost 70mph in 2nd gear!!!

Not even if you use all 9,000 revs? That 2nd gear must be short then!

Yeah, they are very close ratiod but they dont rev that high as standard...

 

[Carlouk]

Going to go nick my brothers CTR and see exactly what it will do in 2nd!

Racing him the other day in my 172 (wet conditions) the 172 pulled away nicely upto 60 as a result of better traction, then the CTR started to pull away after about 70. Its a nice car to drive!

 

[Klang1.6]

defo got over 80 and plenty left in so panik over! cheers guys

 

[pete_pete]

Rich -D yer mine red lines @6800 but will try and rev well into the 7000 mark...

 

[clioboy]

my 1.2 8v does 75 in third,u shore have to wind it up though.
