You are a dill.

GR is a top fella who freely gives of his advice and has a warrie to spin. Still trying to get to one of his dyno days(and the promised tea and bickies!!).

45DHLA is definitely the way to go - however I do have a pair of 48 IDA's here if you want to cut a huge hole in the top of your bonnet - go really well on VW and boxers I hear...its Makkas fault - bought one dellorto and cant stop!!

Who did the head originally and what was done, not what they said was done but did they show you how the head had changed, did they supply you with the cc of the chambers? Has said mate got the qualifications to advise on what is best for your motor? if he has he should know why it is so slow. That brings up another question, how slow is slow? A lot of questions need to be answered before you start throwing money at it. Maybe there is an obvious reason that has been missed. Was it slow when you put it together or has it become slow or have you gotten used to it?


Not trying to be rude to you guys who are trying to help, but pleeeaase read what I wrote. I've answered almost all of your questions already.

Headstud Development (H.S.D) did the head work.

And I also said that it was the owner before the one I bought the car from that had all the modifications done. So no, there's no way that I could have seen with my own eyes what was done.

No, my mate is not a qualified mechanic but is often right about a lot of things. I'm obviously not taking his word as gospel, hence me starting to ask others' opinions.

And perhaps I'm thinking it is slow because I come from my 3L 6cyl Cressida and hop into the Mini. The thing is that I don't know how fast a fast mini is. But I do know that my mate's 1976 Celica shouldn't be able to roar past me with ease. (ps: it's not a standard Celica but is still an old car like mine with a modded old engine like mine granted its bigger but the car is also heavier).

In that case your mini is slow :wink: A properly ported, cammed and carbed mini is a pretty pokey thing to say the least, esp when you're running a big block 1275 or greater.

Not sure about the state of your engine, but I bet that if you did a bit of fiddling here and there, say put a kit through your carb, dyno tuned the carb to make sure it's running at optimum, making sure the timing is spot on etc you'd gain quite a few horses right there and then.

If I were you, the next few steps would be to throw in an LCB and RC40 exhaust if you haven't already got extractors, think about maybe twin 1 1/2 SUs or 45webber/dellorto, RE13 cam and 1.5 rockers, in that order. It should make the little thing fly!

Actually, I can't believe that it doesn't already fly... by the sounds of it at least 60bhp at the wheels is certainly achievable with what you have?? I run at somewhere near 50hp and I think Lillee is at least pokey... at least for sure can keep up with my friend's (GT4 shaped) celica :shock: :wink: Actually no joke through the back streets of my area (roundabout heaven) I give my friend's Skyline GTSt a run for his money 8) but then he drives like a granny :oops:

Mybe finding out what is on the car first before asking for help, it may have all the bells and whistles but if it aint set up right then i would say that it just out of tune.

Yes i send my stuff to him and am about to get on a plane and meet him for the first time, I have had head work done by others and the figures that they gave me and what graham rusel has given me is chalk and cheese.
std cylinder head flows about 93cfm.
cooper s cylinder head about 101cfm
a well ported road head 113cfm
my head i sent to graham russel 138cfm
work that out in percentages if you like but my head flowing 113cfm produced 101bhp so imagine what a correctly set up 138cfm head will flow.
Im planing on bringing over a head form him to do while im there to see if we can get near to 150cfm (like his own cars one) as his own car produces 153bhp.

celica or not it is worth the money hands down.
I have video footage of my car (101bhp) beating 2lt skylines and 2.4 cifero on the striaghts also a FXGT and keeping up with a Honda Vtec. s there is plenty room for improvement.

Dont ever take anyone elses word for it cos if it was that good he wouldnt have sold it, do the specs yourself and create your own monster with as much power as you like in it.

i think the best thing to do if your serious about getting more power is to take your car to a respected mini shop near you maybe LINK and get them to check it all over and give you some feedback as far as is it running well in tune what they suggest etc
cuts out the quess work and you know that what your spending your money on is worth it
i think even if you have to pay 100 bucks or so its worth it

ok, I rang up the head guys and i'm going down to pick up the list of stuff they did... I asked what it was flowed to and when it came to them it flowed 98hp and when they were done it flowed 125hp. That equates to 115cfm so I'm told.

I don't quite understand the difference when they talk in flowing horsepower and flowing cubic foot per minute. What is the difference? It seems like those units aren't measuring the same thing like for instance inches and millimeters are. :?

I might be not quite right but AFAIK

The horsepower flow will be the theoretical maximum horse power you can get with the head flowing that amount.

CFM is a measure of the volume of air that the head flows, rather than the amount of horsepower that could be developed from the amount of air the head is flowing,

Are they quoting flow numbers with valves installed? Is this the standard? I figure it must be because it would have the most relevance.

Hope this helps
