Anyone had their valver dyno'd? If so what was the power at the wheels(not the flywheel!). Add whether your car's standard or modded

Hmmm....

At the flywheels is 153Ps an 17,2kg.m of torque.

At th wheels is about 120-122 i think...

A standar Clio 1.8 16v is about 115Ps at the wheels

Gav
14-01-2006, 23:56
Ps?

BHP = Brake Horse Power.

WHP = Wheel Horse Power

NMT = Newton Meters Torque

PS = Pferdestärke (1.0 PS = 0.9863 HP.) Used by japan

kW = Kilowatt (1.0 kW = 1.34 HP) Used by Germany and other in Europe.

ok - so in english how many bhp is a standard valver at the wheels? :D

To convert from: PS to bhp:

PS / 1.01387

The 172' and 182's are in PS......hence tehy don't actually have 172 and 182 bhp, its slightly under

My black 16 v was chipped...

143@ the fly

110 ATW...

These engines are shit!!! :wink: :D

dunno what mine is... never got round to r/r ing it but it pulls well in all gears so probly 115-120 atw

mine was only 100atw at the gdi rr day :(

but ive had abit of a fiddle, and its run in abit more, new exhaust, filter etc, pulls better now,

17-01-2006, 12:46
mine was rr at 145bhp atw, which is around 170bhp atf, had a viper on at the time tho and now got std with itg, i estimate it to be arond 175atf?

Depends on how good a start you get with the gtech!

Mine said 135atw with a decent start...but i dont think so! Not the most accurate things in the world for bhp calculation.

Good for 1/4mile or 0-60times if you have a flat, dry stretch of road.

I usually go by this conversion...

137bhp valver = 113.3 hp atw

150bhp willy = 125 hp atw


atw figure / 0.9 + 10 = bhp

bhp figure * 0.9 - 10 = atw

This is a rough guide for fwd cars. :wink:

Gtech will show you the final performance...
that is whp - wind - uphill? - ... -... = result by Gtech
And it is very importand what weight you have stated.

PS. Try calibrating it with your rear window resistace on... it works better :wink:

[quote=kj16v]

137bhp valver = 113.3 hp atw

150bhp willy = 125 hp atw

I can confirm that figures...

I have Racelogic VBox II and III in my disposal so i can see some very accurate figures...

A normal valver with 137bhp can make 8sec 0-100km/h

A valver with 150bhp can achive 7,3-7,5 sec for 0-100km/h

Scott-16v!

^:-s . valvers are quicker than 8 secs to 60.

kj16v
18-01-2006, 14:02
^Nah, I managed to own four in one year and none of them do under 8 secs.

Well you've had duds. :wink:

Mine RR'd at 101 ATW but that was a fair while ago and everyone on the day was down on their previous.

Let's see what the HillPower day brings.

Scott-16v!
18-01-2006, 14:44
must've had slow ones then. :wink:

clowo16v
18-01-2006, 17:42
Must have been slow Valvers to be 8 seconds 0-60. Mine managed 7.04 I think when I used my mates GPS system and it was about 7.06 at York. Thats on a standard engine bar exhaust and a different gearbox.

See ya

I used to get about 7.2 to 7.5 with my g-tech. About 7.9 to 8ish with a mate in the car. It was always consistant too.

kj16v
18-01-2006, 23:59
So all your cars are faster than Williams? :roll: :P My starts probably aren't that good and I'm sure the time should be closer to 8 with a proper start. But I really don't believe that standard ones do 7, 5, 4, etc.. secs. Unless I see proof. I'm not just saying this for the sake of an argument - just my own experience.
I Don't mind eating some humble pie if someone has proof!

they came from the factory as reaching 60 in under 8 seconds.
maybe you've not mastered your starts? :wink:

Martin
19-01-2006, 00:19
Pretty tough to pull better than 8 secs on a road surface imo maybe at the strip!

Gav
19-01-2006, 00:23
ive done better that 8 seconds on a long empty stretch of road by me....0-60 1 n 2nd gear

Martin
19-01-2006, 00:26
timed with what??

Ya probably right about the starts though!

wot books/data you been reading? :^o 'cos they're not valver figures, all the figures i've seen on various site etc have been around 7.6-7.8 to 60.

This is what autocar said about it in august 1992. They did an in depth 5-6 page review of the clio 16v vs the fiesta rs 1800. Lol@ jumps out of 2nd gear, thats normall then :lol:

jumps out of 2nd cos they forgot to fit a washer in the box on the line.

Itsd a renault recall, theres a lot of in house recalls which that site someone else put up never said anything about. ren recalls for customer complaints, theres lots of them.

The thing is std isn`t std when it`s stripped to the nads and has no fuel in....maybe the 8 secs is a full tank...ICE and not a perfect road?

Dont think auto car would of stripped there's, do you?

Jason
19-01-2006, 17:36
About 0-60 timing...
I think it has to do with weather you have to change into 3rd gear or not.
I suposse 2nd gear goes up to actual 58mph, but you should see 60+ at the speedometer.
So it all cames down to how acurate your speedometer is :wink:

No m8 I meant Matt getting 7.0...so 7.4 is about right and 8 would be because of extra weight like ICE that Autcar wouldn`t have added

Ah right, with my g-tech i used to get 7.2 to 7.5 and obviosly if you pull off a bit shit or spin the wheels slightly it used to creep up to like 7.7. With a friend in the car i used to get around 7.7 to 8.0 with a good pull off and super fast gear change lol. Ive had one as low as 7.0 but tbh it was a one off.

http://www.carstats.co.uk/
Put in 'Renault' and 'Clio' . Look at Clio Williams and Clio 1764cc

No ones answered why their 7.0 sec standard Valvers are all faster than Willy's!! From our very own site:

[Williams] PERFORMANCE
0-100 kph / 0-62 mph 7.7 secs
Maximum speed 134 mph/215 kph
Drag coefficient 0.33 Cx



Anyway. I'm sure I'm not the best launcher, and a good 16v with a good driver can get between 8ish and 8.5. But as for this Williams, and Astra GTE smoking performance off the lights - hmmm...:-k

:) :)

Scott-16v!
19-01-2006, 18:39
well their site is wrong andd that mag is right :P :twisted:
a healthy standard williams should be more than 7.7 to 60 imo.

G tech is good but not very accurate.

A normal valver with rev limiter to 7300rpm, with 2nd gear has 98km/h.

You can not say that you can achive 0-60 in 7sec in a strip cause on the road is different.

My starts are very good and from 1st gear to 2cn i need 0,2-0,3sec and for 2nd to 3rd i need 0,4sec

If someone with a standar valver does 0-60 in 7,4sec what quarter mile can achive?

FlamingMonkey
20-01-2006, 10:34
I did 6.8 in my Willy at York before Cams :P

To be fair IMHO having owned both, they are not far each other to 60, just depends on the launch, when in 3rd tha where the Willy comes in its own I reckon.

Plattsy
21-01-2006, 01:29
if a valver is 8.9 0-60 then whats an rsi? rsi is 8.5!! lunners right rsis are quicker than valvers lol.
rsi is 8.5
valver 7.7
willy 7.2
Not much in willy and valver, willy just got more low down torque, my mates standard valver hit 0-60 in 7secs flat with the gtec and i also timed a completely standard suzuki swift and was 0.3 secs off the book time at 1.4mile. if a valver takes 8.9 secs to 60 then youve owned a dog with a led weight in it!

21-01-2006, 02:29
Tom16v...with his hybrid did a 5.9 0-60 in this 152hp atw hybrid....

That works out at about 179bhp (Nana teritory)

Not sure if thats accurate (5.9) but im sure low 6's is what most stripped willys do...

Also i did read...cant remember where...but valvers are slightly quicker to 60 as they only need 1st and 2nd, where as willys need 1, 2 and 3 before they are doing 60. Dont know as i run a JB3!

I thot the ratios are the same-ish!

So much BULLSHIT flies around in magazines/reviews etc RE : willys and valvers. Best thing to do is drive the thing and make your own decisions/comparisons! 8)

Craig
22-01-2006, 01:36
stew its the lower limitor in the F7R that means a 3rd gear is needed for 60!

Never done a proper 0-60 in mine.

It seems quick, probably about 8 seconds is what I've managed so far with a 'normal' start. With an aggresive start it'll be about standard me thinks.
