Hi, I am wondering if anybody knows about suitable head specs for the EVO001 cam.

“Both Noah 1293cc with 102bhp and Justin at Mini Spares 1380 with 127bhp have these cams in their minis.” - (quoted from Minispares)

Curious to know how Justin here got 127bhp, if anybody has even a vague idea please share.

If I could even get close to that I would be pretty happy (I.e not offset bores etc)

I assume this cam is a race cam but what else is in the motor it would have a fully lightened and balanced crank, rods, pistons, fly and back plate set up, it must have a 37-31 valve 11 stud head ported correctly,  a decent exhaust system,

well you won't get anything without offset bores not 1380

It’s got DURATION 264 EXHAUST 268, LIFT INLET 264 EXHAUST 289.

It’s an alternative to the SW5/266 sort of thing.

It's a fairly hot road cam.

How much boost pressure are they running ?

The Evo001 is a nice cam for a road car or even a rally car used mainly on gravel.
But again there is the emphasis on BHP whereas it is best mid-range torque that is needed for road use. The Evo001 does give good torque.
I, too, am sceptical about the 1380 giving over 120 bhp with that cam unless it is forced induction.
The Evo001 is a good alternative to the Kent 266 or MG Metro cam.

[whistler]

I fitted an EVO001 cam into my wife's 1330, with an MG Metro head and a HIF44. Seems just an improvement on the MG Metro Cam which I have in my 1293. More low down torque. Wouldn't say this is anywhere near the spec of a race cam; just a very nice road cam.

[Orange-Phantom]

It is aparently meant to be a nice road cam, good torque, I'd put my money on the SW5 cam but then I'm biased and like the Swiftune stuff (made by Kent cams).  The Evo 001 should be a tad hotter cam than the SW5.

 

I'd also second what Cooperman has said earlier about the 1380 was pumping out 127bhp without forced induction.  Methinks they are embellishing their figures quite a bit otherwise!

 

If you look at the cam graph from Swiftunes own website on their SW10 which is their version of the Kent 286 cam, their 1380 is producing 125bhp and the SW10 is a wilder cam!  Not being disparaging to Mini Spares (I've bought a lot from them over the years and they have always been excellent) but I'd much rather trust Swiftunes figures than those from Minispares!  Something does not stack up with the Minispares numbers!

Thee is always a lot of talk about this cam and that cam, but in the real world, on a road car, is there really any difference between the mid-range cams like the MG Metro, 266, Evo001, etc? 

 

Of course, those wishing to sell cams will say that there is, but having been involved with competition (rally) Minis and other cars since goodness knows when, I can tell you that even on special stages where seconds count, the difference between fairly similar cams is not really noticeable.

 

The two main ingredients to driving quickly, which is why up-rated cams are fitted, are top quality engine building and driving well. Look at the cam graphs and see where the power and torque are, then match the graph to your requirements. 

 

Huge BHP figures are great for bar-room bragging, but for making good smooth progress on public roads requires best torque at comfortable revs and gear ratios and final drive ratio matched to the required use.

 

My personal favourite cam for road use is the Kent 266 (or MG Metro - they are very similar). Torque is strong at mid-range and maximum power is at 5700 rpm, so there is never any need to rev much beyond 6000 rpm. Then build your engine with the greatest care and accuracy.

[Rorf]

The EVO0001 biggest advantage seems to be its cheap price vs SW5 which is much more expensive.

 

Wonder which one will last the longest

Totally agree here Peter.

 

There's often way too much 'fixation' on Peak Numbers and little paid to how it gets to these Peaks.

 

I've always found on the road, the lesser cams way more fun than those giving high peaky numbers.

 

On the track too, it can be a similar story.

 

A very famous F1 team in the 60's won the world championship 2 years running despite having engines that were some 30 - 50 HP less than their rivals because their engines developed better power at the lower end of the spectrum.

My historic FIA Group 2 rally 'S' has a 286 cam, a 3.9:1 FDR, a SCCR gearbox and normal helical drop gears. On the road it is fine so long as I keep the revs up. Peak bhp is at 6400 rpm and it revs easily to 7000 rpm. It is great on tarmac stages and mainly tarmac road-rallies, but for normal road driving my old Innocenti 1300 Export with a virtually standard engine and a 510 cam was much nicer to drive and really just as quick overall. I didn't need to rev it past about 5500 rpm and it was easy to keep the speed up through twisty corners in a smooth manner. With the 'S' the revs are critical and it has to b e driven 'hard' to get the best out of it.

 

The club rally 1990 Cooper I am currently restoring has an MG Metro cam, a 3.44:1 FDR and a standard gearbox. I am going to fit twin HS4's this time and do some more gas flowing to the head with a CR of about 10.2:1. It should be ideal for a club rally driver who wants to use a Mini with good torque from about 2800 rpm to 5500 rpm.

 

The 998 (1060) Mayfair I have awaiting re-restoration has a 510 Cooper 'S' cam and it went very well when first we built it.
