"tamer" = more fun at lower revs with bags of torque...

its a short duration high lift cam: excellent for the road where revs are 'low'.

bags of torque, good with emissions.

runs out of grunt from 6rpm... but seriously if you run a road car at 'high' revs all the time then how long do you think its gonna last?

Thanks thats a good reply. I presume you use the SW5 yourself then? if so what size is your engine? and what are your power figures? if you know them.

I rarely rev over 6K as in the current engine it would be pointless anyway so I am happy to have more torque.

I will probably go with the SW5 then

Have built a few engines with this cam - 1293 through to 1380's - carbs and SPi

Its not a high, peaky HP type of cam... it will though give you a load of torque right where you need it when driving around town and on motorways. smooth idle with no 'lumpyness'. good on fuel and generally spot on.

because the torque is spread across the range, you can (and i have) built it ontop of the wide ratio gearbox sets and you do get the best of both worlds when coupled up with a 3.1 diff: excellent acceleration from low revs through to excellent cruising on the motorway.

if, however: you are building a track monster or interested in just HP then its not the cam to use.

Because you can drive it 'sensibly' you can use standard valve springs (so no more wear occuring due to heavy springs), and you're not revving the nuts out of it = last longer...

Use the SW5, sell me the 286 :)

how much you willing to pay for 286?? i have one!

[runkthepunk]

Worked head I agree on, the extra 70cc however isn't going to make any noticeable difference on the road,

I hope there is a noticeable difference with the +40 over my standard engine thats the plan anyway. The pistons are flat tops so have been told the compression will be quite high (not too high though)

I will go with the SW5 and probably sell the 286 then as I said its brand new so hopefully someone will want it.

your 1275 with +.040 will make a 1310. That with flat tops and sw5 will be a very tasty engine. i have a couple new reconditioned engines for sale 1400 and a 1445.

[racingbob]

need to make sure compression around the 10.1
so check those flat top pistons are ok

Kent Cams 274sp.

Will drive the same as a SW5 but provide much much more power.

The last 2 SW5's I've fitted, have resulted in disappointment, both owners expecting more. Despite been told before they got there cams to fit a 286..........

That Bill Solis DVD has a lot to answer for ey? I’ve not seen one 1380 that will pull 100hp out the bag with this cam.

[Shifty]

As already said it does depend on what you want to use it for, from the sounds of it I think you'd be happy enough with an sw5.

I've got one and its not a monster cam, and you don't really know its there so if you're looking for a smooth torquey motor then it could be up your street. My 1015 makes 68 bhp and gives good fuel economy.

The other option could be sw10, thats supposed to be a bit more usable than the 286.

Did you ever make a decision in the end? I'm going to be getting my 1310 back and i'm deciding between a Kent 276 and SW5-07 :/ haha

[KernowCooper]

My 1330 has a 276 and I cant fault it, has a kick the sw5 doesn't and idles ok little lumpy and pulls strong from 2750-6500. I have a balanced bottom end and tuffened crank with a centre main strap.

Yeah I decided to stick with the SW5 but the engine is still not in! I live in Bournenmouth, work in London and the car is in Staffordshire! so never get chance to get up there.

 

Realistically for me I enjoy driving the mini (although I haven't for a while!) and going days out etc in it thus I wanted the smooth everyday driving with just that little extra bit of poke and the SW5 does that for me. I have a Peugeot 106 Rallye which as a daily driver isn't that much fun because you have to rev it so much to get the enjoyment/best from the car and I didn't want that for the mini.

I'm building a 1330 and the cam is still on my "to be decided" list ... but I was veering towards a 276 ... what I don't want is an engine with little or no power below 2000 and the 276 is reported to be OK from about 1500 rpm .. correct?

Yes mate correct I spent a long time getting my custom needle right so it carburates correctly throughout the range, mine idles at 1000-1100rpm ish and pulls away on flat ground with a sniff of throttle, at 1500rpm its pulls ok, and once past 2250 its away and at 3000+ it takes off to 6500rpm.

 

The secret is in the setup if the needles not right and the timings not got the correct curve, then it wont drive as nice. I have seen cars where they say my cams causing very little below 2500rpm and its the tuning off by a mile.

 

I recommend a correctly setup 276

The reason the SW5 did not have a kick was because it would have already been in the 'kick' range, it pulls from so low down, if you put them both on a rolling road you'd have noticed a big increase in torque when the 276 kicked but a much flatter line with the SW5, the SW5 may not have produced quite as much torque at high revs but much more low down

[KernowCooper]

World of difference though between a 276 and a SW5 overhaul though they are not even close.
