Post subject:  Russell cams rule
Just thought I'd let you guys in on this e-mail I just sent Graham Russell....

'Just had that magazine feature 1360cc engine with the RE13 104.5 LCA cam on the local rolling road... Astonished the operator (Pete) completely! Even with the 'OK' MSC inlet manifold and 'done in a big hurry head' it gave 119bhp and 94lb ft torque. Pete says that is the best he's ever had in it's class on his rollers. The 'usual suspects' type 1380 with 286 cam usually struggle to get 105bhp and 90 lb ft. Plus, the 1360 is taking full throttle at 2,300rpm, the others really struggle at 2,800rpm. He's mightily impressed. I'd like to do another head for it with a big bore inlet manifold and see what gives - but it's off to France next week. Its as huge a grin to drive as yours is... I was laughing my head off all the way home down my 'test track' road. Just fantastic. '

And this motor uses 1.3 rocker too...MSC inlet manifold (newer spec one), welded advance dizzy, 10.5-1CR, single HIF1.75" carb with CST filter kit.

Well done GR & KC ....

Just a quick questoin, why do you guys (Pommies) get such high Dyno readings ?

We tend to use HP@WHeels for most of our Dyno days .... and most big-bores are reaching the 55-65 mark (encept the russel engines.. they are more likely to be in the 60-70 range...)

My 998 Turbo scored 73@wheels, and seems to be higher specced than most of the engines i see in Miniworld, yet they are pulling 85, and 90 hp !!

Just a question ....

It might be something to do with the salt they sprinkle on the rolling road in winter up there?!? :lol:

Maybe they have adjusted bhp reading to approximate crank power?? :?

perhaps bhp = British HorsePower :)

It`s just a figure,,,,not really that important in the "Big Picture"

what is important is that it`s a figure for "Comparisons sake"

Apples & oranges sort of thing :-)

same day, same atmospheric pressure, same temps, same rollers, But different car/engine, then we have an apple against an apple

& yes, they do tend to "guestimate" the power at the crank in a lot of cases.

Of all the "so called Hot" race minis that i drove in England when i was there, NOT ONE of them had anywhere near the balls that my roady 1510 had, & that included a couple of turbo minis & a 16v K series powered thing. But then,...that was just using the dyno in my bum :-) But !!! the 520hp twin turbo porche that i drove,,,welllllll, that had a bit more than i was used too :-)

addmitedly, the Phoms have better fuel,,, have colder climate,,, & probly do have "looser dynos" too :-)

well done GR & KC tho, you guys really are the ones balancing out the scales, doin the homework & sorting the crud from the good stuff these days, top notch!!!!!

Ahem, well done Graham Russel.

It's his cam, he developed it, he grinds them, he named it after himself... Sorry Keith but we already knew they were good :lol:

The rolling road is a Sun type, and gives crankshaft bhp based of a power loss type deal. The figures themselves are relatively insignificant on their own as I have always ben at pains to point out. What is important is the comparison of other builds of a similar type on the same rollers - hence the comparison I gave. And pointed out by others in this thread.

There are rollers over here that give wildly high readings and some that give really low ones. It is impossible to compare one set to another unless you do what I did some years back - go to one set, set the motor up, take readings, then high-tail it down the road to another set and check the readings, then off to another and same again. Three sets of roillers in one day - and quite far apart. It was interesting and gave me something to work with when folks asked abot comparisons. Still - the only way is to use the same rollers all the time to build up a picture/reference library.

I know GR developed the RE13, but he does not grind the ones I am selling over here. GR gave me full permission to get Piper to grind the profile so we could market them in UK for which GR gets a royalty. But this has been aired before. I am advertising them as 'Calver ST cams develped in conjunction with GR' because nobody over here knows who GR is. I'm sort of spreading the gospel according to GR in the 'new world' if you like.

And although some over there know how good GRs cams are, there are still a heap of you who keep quoting/insisting on Kent Cams as if they're the only way to go - just because a bloke over here said they were 'the ones' 20+ years ago.

Did not mean to imply anything but to give credit where credit is due. In this case, credit is due to one person only...

Whacking one into an engine is what many of us have been doing for quite some time so congratulating someone doing this is like congratulating all of Ausmini who have been waving the RE13 flag since Ausmini's conception.

Anyway that's all I have to say, thanks

For the redord, my collaboration with Graham has netted benefits on both sides. For instance - my association with Piper has proven benefits because they are interested ion developing/enhancing A-sereis cams - unlike mother resting on their 'laurels'. Cutting a long story short, Piper have a cam that fills the only gap in Graham Russells cam arsenal - the HR255. A superb road cam that gives smooth idle, loads of torque, low emissions and is very strong up to 6,000rpm. If this sounds a familiar claim its because the SW5 is almsot identical to the HR255. So Graham is going to be selling the HR255 profile. Fair trade. KC

The RE-13 cam is sitting on my bench at the moment as I have to redo the engine plate gasket and putting on the timing belt(bloody bolts they supplied stripped the threads on the engine plate!!). I have yet to try the cam but I am chomping at the bit to get the bloody motor in the car. Still trying hard to make the original motor let go(239,563km and still ticking!!!) but I am sure I will have it in shortly.

After reading your opening post, I am keen to see how the cam goes with the 1.3:1 roller rockers(MS ones - that ruddy green colour) and the 202 head with peaks removed. SHould make the little 998cc(30 over)go like a scalded cat!!

Just one for dialing it in...it was installed"straight up" but any advice on how to dial it in would be great. I had the vernier gear on it but the Triger belt has no adjustment in it. Can I run the cam straight up or are there tricks to getting this cam to work well(might have to come to the next AUSMINI dyno day or just turn up at GR and get him to do it...lol)

Hooroo

well thier are other things that he does when he builds engine and he test parts and helps many people out with thier questions to help people get what they want so he put back in what he gets out
Some people maybe pissed off with him but thier are a lot more that are more than happy with the assistance that he has given on many fronts of engine building and performance
Cant say I'v read much of his suff thou

If GR it getting royalitis from KC thier is no way that GR can complain as it was a agreament between the two of them as gentalmen or partners. As the people who have had work done by GR, he is a very busy man already and if he can make more money buy selling something 8)

Don't forget thier are other secrets that GR has and he does not give them out lightly to many others :wink:

Gr and KC are both good men as they inform us about how we can improve our love for Mini's an d help us when we have a question :!: Just depend's on how is closer to You.

ow and willy..HP does not win pub Battles..thats fools who think they are some they are not.

if you have a print out its states what you engine did on a paticular Dyno and then you can make aeducated comparison

My rant

Rob - dial it in at the valve - it's here where the timing counts. KC

GR has never complained about our collaboration and it's results, nor the agreed sales of products. He is a great fella, a decent and honorable man and now count him as a good and personal friend too.
