Anyone know where I can get alloy hubs for a sierra?
Cheers!

You after ally uprights, or the axle assembly?
I only say that because it would be a very brave (or stupid) man who attempted the axle/drive flange in ally. Although it can be, and is, done in
steel axle and ally flange. But not any ordinary ally, either.
Uprights are a 'been done' item.
Cheers,
Syd.
Looking for hubs, not the uprights. Can only find them for escorts. granadas and a few other makes of car.
IIRC there isn't such a big weight saving replacing the Sierra ones with alloy. Could be wrong though........
Phil
do raceleda do them?
Nope! They do Cortina hubs.
Starting to see a little sideline in Sierra hubs looming!

Burton power.
Not that I can see, escort and cortina there.
Do you mean uprights?
If so car builders solutions but you want like the price!!
They fit ford sierra bearing and cost lots!!!!
Why don't you get someone like us the Fab you some light weight steel ones?
Nope, dont mean uprights! Using the Dax fabricated uprights on their CCAR system, just fancied loosing some wieght on the hubs as well.
Have you weighed the sierra hubs?? the cortina ones were about two Kg's so worth changing to ally jobbies, but the sierra ones 'Look'
as though they would only weigh half that as std, and if that's the case is it worth your hard earned to loose half a Kilo per side ??
Jason
As yet no, I havent weighed them. Need to split them off of the uprights first and then I will.
Looking to save as much as I can, as I think saving the weight will be cheaper then tuning the Hayabusa engine!
Still, ultimatly I may do both!
There comes a point though, where the cost for the potential weight saving would be far better spent on something like getting the car setup properly
or having the engine professionally tuned or a custom exhaust made by someone like Tony Law.
Having said that, if you can afford all the above AND lightweight parts, then why not.........

Just out of curiousity, how heavy and how powerful is the team hellfire car?
When we last had it weighed, it was 506kg's IIRC. Since then, we have shed around 15kg's on lightweight brakes and disks so would expect it
to be around 490kg. Measured 154bhp at rear wheels on Dyno at Holeshot Racing.
The figures quoted above are ACTUAL figures, so you're lookin at about 314bhp/tonne.
Phil
I was just curious to see what I might expect from mine when I get round to weighing it and getting it RR'd. It's a standard indy with a carb'd bird with air filter and I presume a dyno jet or similar kit fitted. There is some weight to shed yet as it has the vented disks at the front and sierra calipers all round still.
Even without the lightweight calipers and discs, yours will still be devastatingly quick with a Blackbird engine
Phil
In all fairness I owuldn't know, as the only other 7 type i've been in was a basic caterham last year! It's also my first ever rear
wheel drive car!
Well Im aiming for around 430-450KG Rush with Hayabusa power. Think these make around 175bhp as standard.
I think the power varies a fair bit depending upon year. I've seen the '01 engine rated at 158, but I don't know if this is at the crank or wheels.
Got an '03.......3.8k miles on it
At the crank, yes. Most manufacturers quote figures at the crank not RWHP

Yup, '03 busa rated at 175 bhp@9800 (probably at the crank) and 102 lb fts@7000.
Phew!!!
I had the same issue with mine. The haynes rates it a mere 144.6@9321 but I know it has 164@10,000! Which is a much nicer figure.
Same goes for
torque, haynes say 85 lbfts@7213, I've found it rated at 91.5 lbfts @7250. And remeber that you'll probably have a free(er) flowing exhaust
and airfilter than standard so should have even more power than that!
Would like to try and get around 200 out of it for the moment. Not partuclarly interested in going forced induction as I feel this may make it a little more fragile. Oh and the cost!!!
