Just spoken to Andy Burns of Kent Cams (01303 248 666) and asked him which cam would suit my 94 Spi.

They advised me I could go for the MD274SP/MD274 and also recommended the MD246 for drivability, on my SPi !
These are the ONLY cams he would suggest on the Spi

I mentioned that the website states about the power band of the
MD274 = 1000-6000 r.p.m.

http://www.kentcams.com/product-details/241/Camshaft/Camshaft/MD274-Sports-Injection/

MD274SP Scatter Pattern = 1500-6500

http://www.kentcams.com/product-details/1145/Camshaft/Camshaft/MD274SP-High--Torque/

and that the MD246 = 1500-6500
http://www.kentcams.com/product-details/238/Camshaft/Camshaft/MD246-HIGH--Torque/


I was advised that the MD246 will NOT go to those top figures and that the power delivery is from 1000-5000 r.p.m.


As far as I am aware, most of us think that ony the MD274/MD274SP are the only cams that can be used on the SPi
(feel free to correct me on this).


So Andy Burns of Kent Cams said he is happy to give his name out as a reference.

Hope this is of use to us Spi owners



List of cams are on this page, just for navigational reasons

Oh and forgot to add that the said MD274 power band kicks in around 2500 rpm, which I think is what Sprocket mentioned on one of his many SPi posts.

The only real proven options are the MD274 and the SW5. The SW5 similar to the MD246

hmm, I might go the SW5(i ?) route then seeing as the MD246 is unproven in the SPi role. Simon at Minispares says that the MD274 was designed way before the Spi was out, but he doesn't forbid using it.
Better to err on the side of caution I think ...

Just spoken to Andy again after your comments and speaking to Simon at Minispares with the original info. I have a lot more information from Andy at Kent, but he agrees with you and explained why and was very helpful. If you need info, am happy to answer via PM

Maybe Simon knows something I don't (which generally happens a lot,) but I was always under the impression that the MD274 was specifically designed for the injection engines.

What makes the MD274 special as far as the injection engine is concerned is its wide lobe seperation and full lift angle of 112 degrees. It is the ONLY Kent Cam for the A series engine that has this wide seperation angle, all others are around 106 to108 degrees. This leads me to believe that the MD274 was designed specifically for the injection application, or, as a cam for turbo charged engines, but happy to be proven wrong.

It is however easy for people to become confused with the MD276 cam, which has been around since the early 80's

The SW5 has been proven in all aplications, some people swear by it, but for me, the MD274 is the cam of choice in an injection engine.

Hi Sprocket, Andy at Kent confirmed Simon was wrong about one small point. I will PM you the information that Andy told me earlier on the 'phone.
Suffice to say that you are correct in your thinking. Please bear in mind I am not technically minded, I just do a LOT of research on any subject
I started quizzing Andy at Kent about his camshaft selection choice and he did impart some very candid information about which cam he would go for and why.
I would rather pm you that as I think it is only fair as he was very honest and open to me about his opinion.

Would be interested to know too.... please PM...

done !

Where can i get this camshaft MD274 (link) and how much?

Does it really make much of a difference?

When does the extra power as such kick in?

MD274 is a Kent cam so you should be able to google it

I don't have it myself, but here is a youtube video of it
