My spec currently
Spi cam
Spi head
9.4:1 cr
7psi
No intercooler.
T3

Basically the engine runs out of puff at 5k. It comes on boost at 2.5k ish.
I have seen a md500 kent cam for sale. Am I right in thinking it's very similar to n/a metro cam?
Will this help the engine produce usable power till 6k?
Whats the going rate for a new but unused Kent cam.

The SPI cam that you're using is actually a standard 1275 profile and incidentally the same as the Metro Turbo cam, (but nothing special) and I recall that it doesn't really like more than 5000ish RPM on a NA SPI engine either.

I believe the 500 is the MG Metro cam profile that a lot of users on here favour, but I'm sure there's several other choices that will do the job equally as well.

The MG cam will work nicely, and will help towards higher rpm. But running out of puff can be lots of things. Fuelling and ignition advance are worth looking at first.

Then any restrictions in the inlet side, what spec head have you got?

Years ago I ran a boggo Metro 1275 in a Mini, the standard cam does make the engine very "breathless" higher up, a different cam will help a lot.

My kc500 ( we are onabout the n/a mg cam arnt we? )
That used to hit a wall bang on 6300rpm i could push though it with boost but it felt quicker to change gear below this rpm

Yeah it says kc 500 on the end of it. If I could have power till 6300 I would be more than happy
Its on the bay e at 100 starting bid and 8 postage. Is that about the right money?

My secondhand MG Metro can lets the engine run to well over 7K if i let it (like last weekend) but it does have the benefit of Turbophil head and a Robert tune.

Mitsi Evo 7, 911, Cossie. & all the chavs ...... won no problem

yes its the way to go with the cam change, a modded head would compliment each other and you could run say 10psi boost with no intercooler on good octain fuel with 26 ccs in the chambers

my experience with this is

1275, intercooled, 10psi, worked head, metro t3, sw5, 2.9 final drive - power band between 2500 and 5000rpm, max revs was only 5.5k. was a nice engine and went well, didn't like to rev though!

1380, same intercooler, same worked head, 16 psi of boost, phase 2 cam, hybrid t3, power band beween around 2800 - 7500 rpm. will pull right up to 8k on a standard bottom end (bar the ultralight flywheel). have lowered the final drive to 3.1
