My RR Power Run - 173bhp & 189lb/ft

[Tom_16v]

A few people have asked me about my power/torque figures being slightly high for a lowly, if somewhat tuned, 1.8 16v......

.....well the answer - wheel spin lol!

Had some problems getting a decent run on the rollers and getting readings, but the first run lit up the rollers (well my tyres started smoking lol) and the second run wheel spun just after the trigger point.

The graph showed 189lb/ft at just 2000rpm, thats more than a Williams! hehe

Nice - wot mods?

As an ex tuned 16V owner - and with the very greatest of respect - my old "171bhp" 16V probably really ran about 155bhp as I found out when I had it RRd myself. The torque was also about 130lb/ft at peak, perhaps 110lb/ft at 2500rpm if I recall correctly.

Again, with the greatest of respect, I cant see how even a massively tuned F7P 1764cc could make 189lb/ft of torque at 2000rpm. Im sure someone like BenR could explain further, but the very nature of the crank and multi-valve head make it pretty much impossible without some serious, serious work. The power, maybe... just maybe - but that much torque, Im still unconvinced.

I understand that youll think what else can you do to prove this as youve already had a RR power run done, but I think youre going to have a bit of a surprise at the next RR day you go to. Where was this tested and what are the at the wheel figures?

My old Valver probably wasnt much slower than my standard Willy is now in a straight line, but the torque spread on the Willy makes it quicker in real life. If, as the RR claims, yours now makes 189lb/ft at 2000rpm, then you have a true Williams slayer. In fact, itll kill any Cup, 182, 172 and probably V6s if you really do have 189lb/ft at 2000rpm.

Suffice to say that Im the first Williams owner in the line to offer my car as a basis for comparison! (providing youre not too far from Wales!)

 

[weight]

189lb/ft * 1.35 = 255nm

v6 has 300nm

172 has 200nm

willy has 175nm

16v has 158nm

sorry dude something isnt right

mine wheel span as well (when i had it done) but when they got a decent run out of it it was 184nm

was putting out more than any other williams, that wasnt using a chip.

Heh did anyone actually read what I wrote ffs!

The car wheel span on the rollers or did summit i.e. giving a false reading.

The graph has a pretty much vertical line at 2K where it shot up where the error occured!

At what point did I say my valver was actually putting out these figures.....

Haha!

You have proof of lots of power - you should be in driving tales telling Dave Gti how slow his car is compared to your valver

Tom_16v - sorry dude, but it did sound as u were claiming those figures. but now i know

wheelspin shouldnt show as a torque gain tho, that is worrying

IMO it should show loss or nil gain, as mine did

 

[Tom_16v]

We werent sure what it was, as we (rr mechanic and myself) didnt notice any wheel spin, but it happened just after the trigger point.

Maybe just a simple software error or summit I dont know.....

I dont want to cause argument but why put it under you avatar then? Doesnt that signal to people that your car produces that kind of power?

Just an observation laddy...

 

[weight]

maybe dude

theres something pleasing about seeing ur car wheel spin on the rollers in forth at nearly 100mph tho

 

[Tom_16v]

lol!

At first I thought something under the bonnet had caught fire cos wed hooked a fair few wires up under there, but he just looked at me after he backed off and said its ok, its just your tyres hah!

Profile changed...... (Note the sarcasm!)

 

[Daz.]

lol - I like it! Profile Changes too...

 

[Tom_16v]

Impossible!

LOL!

 

[Ben H]

Ive been had! But still, it was only the torque figure that led to any questions!

So, what were the real figs?
