Kent MD286SC no question about it the best road cam has always been the Kent286SC that is accept the VP8C which with out doubt is the best A series cam in creation.


I agree with Paul, Ive driven loads of 1380's with varied cams, my current race car build has a 296 scatter but Im changing that, but I found for road light track use the Kent 286 to be my favourite for best of both, in my old 1430 track clubman I used a VP8C and it was an absolute blast*happy* I loved that cam*smiley*

I have had no experence with the RE13 seems like a good profile and Graham sure knows what he is doing, I would not see it as a Trackday cam more a spicy road cam. That said with the right spec it seems to do well and makes the power,

At the end of the day if I was looking to build an all out weekend warrior I would use the VP8C and spec the motor accordingly. If I was trying to build an every day fast road 1380 I would fit a 286 with a GT gear kit and a 3.44 CWP and enjoy all day long.

Go for something around 300deg, my bp300 lacks a bit of the torque of a 649, but its a bit more tractable off the line and revs for a bit longer too.

Lookin at the spec and FD you're using I'd think you'll be disappointed with anything less than a 300degree cam. So anything like a 649, BP300, MD296 or above.

I totally disagree. I wouldn't be stuck in traffic with either. Also, this range of cost will seriously increase the cost of building an engine.
Proper pistons, one piece valves, ultralight flywheel, CR-box, a PROPER head, big exhaust, Weber 45 etc.

Too much for a road engine in my book.

consider the rest of his spec too tho, all the crank work etc, its clearly not an average low cost build... I think you're just being a pansy *tongue*

Agree with you on this Veg 300 cam in a road car is just pants, in fact a 296 is a pain in the tits let alone a 300,
An for the record I have on no less that 4 different counts got more power from a MD296SC than any of the 300 cams, 5 PORTS dont like 300 cams Read the yellow book.

I have run an RE13OT and found it excellent for road work and it pulled over 100bhp on a 1380 with twin 1.5" SUs.

It is a little lumpy on the bottom end and doesn't start to pull until 2-2.5k. As I do Historic Rallying, which is largely autotest based, I swapped it out for an SW5 as I needed something with all the torque from tick over and less power up the revs.

I am willing to sell the RE13 - it has done about 1,000 miles so just run in *wink* £65 + post

What does the "OT" suffix mean? I though he had a turbo specific version of the RE13, called the RE13T, which I assumed meant turbo.

TBH I'm not sure - Calver sells the RE13OT and the RE13PP. The OT is the slightly milder of the two.

Graham Russell may well do and RE13T as a specific turbo cam.

I'll do some digging...

story of my life, i know loads of people that go for 266/276 etc and are so dissapointed with what a 'fast raod' cam offers

defo can't agree,
these nice names cams vp8c, agsp, mspd sl13 md296sp, re13ottpp; etc etc can go well if well build and test on a track.
What I know is each time we removed one of these race cams (agsp, 296sp, 286 sp, 286, and a re13) and replaced it by a 544/643 profile, the mini was putting again a big smile on a face instead of complains, mainly because it was usable and plain everywhere.

I think the key to a succesful choice of cam is having it matched to the cylinder head. You can only do this by trial and error.

Md300Scatter with a 44? If you change it for a 286 you'll, have the same top end and more torque..

Didnt mean to sound an arrogant twat by that but, I built my Sprint originally with a 296sp, it weighed 650kg and showed 134 bananas on Swiftys dyno bench. My wife drove it on the London to Brighton run from Crystal Palace, through London traffic while she was 7 months pregnant - shows how easy a 296 is to drive.

Ive since fitted a 310sp and a Salisbury diff set at 120lb, the 296 showed 140 Baldwin bananas, the 310 shows 155 Baldwins, she has driven it to work and to Tesco for shopping no trouble.

Between Gavin and I we have run nearly every cam out there and we kept putting off fitting a 310 because everyone said theyre undriveable - Bullshit! I say, if there was a cam that would give me more power and more undriveability I would fit it and still gladly drive it on the road.

This thread is about a cam choice for a trackday car, if you fit a little cam - 286 or less you will regret it as soon as anything else powers past you, then spend loads of money changing it for a proper cam.

Paul

I seriously doubt it!
