[paul burney]

Hi all

Thanks

[mowgli]

perhaps also a good idea to remove your complete address from your profile <<<< :)

lol Yeh i noticed that aswell.

[mowgli]

its ok, the sport won't be there lol lol

[paul burney]

Yh av changed the address now what a tool lol how can a get it above 100bhp any advise

[mowgli]

head work. get the ports tidied up, who does the blydenstein work these days???

[garyc]

I thought Ivor Searles took over Bill's work.

Massive disapointment the car ran 64 BHP today and the guy said I need a new dizzy does any one have one for sale. Also do you think that the dizzy would make such an impact on the proformance. What things can I check my self to get it where it should be.

So gutted

I have a distributor from a 1300 - PM if you are interested/can post.

Usually its the carbs that need setting up properly - did they do this?

[marc69]

That must be a mega dissapointment, does it feel like it only has that when you are driving?

For an electronic dizzy to affect performance , it can only be that the timing is set wrong (the engine tuner should have sorted this easily) or the vacuum for the advance is bust but, the vacuum shouldn't make a difference of almost 30%.

[garyc]

They are prone to breaking the sping and weight pins. Did they say exactly what was wrong with it?

[martsnova]

ive ran the black dizzy cap set with no vac advance on a rally car . cant see thats the problem cam timing? or carbs you running a vernier pulley on it

[Royston]

I would expect the guy that tuned it would have given it a thorough check over, and maybe a compression check, especially as the results were dis-appointing

Has he given you feedback?

Did you service the engine beforehand?

[paul burney]

I collect the car on Saturday I rebuilt the engine before it went in all looked ok. When I pick it up al get the full story and let all no so a can take from there. Am still in shock lol

[mowgli]

if the diaphragm is shot, you can get it massively retarded. it will run, but be flat as a fart. but for a power run, advancing the timing would be ok.

[paul burney]

The diaphram was nakered on the dizzy so I have replace it now what sort of break should I be looking at at the wheels. Oh and my starter motor has gone lol no one has one by any chance lol.

[garyc]

Without knowing what they did on the rollers its hard to tell. If they blocked the air pipe and set it up properly then I doubt you will see more than 64. The vac advance has no effect when your foot is flat to the boards like when they are setting up on the rolling road. If they just gave up and didn't set it up then may be more.

I have some starters, £10 plus postage.

[paul burney]

A just don't understand every where I read and look it says they should be 93bhp at the wheels and myn is 64 he did set the timig up and block the advance pipe so why only 64 at the wheels

an the flywheel
Paul the figures I quoted were at the flywheel, not the wheels

My 1.3SR with 4 branch, sports exhaust, K/N airfiter, diy polished/ported head on std 1B1 Pieburg carb produced 66hp at the wheels (I estimate @ 80-85 at the flywheel)

[paul burney]

Arh ryt thank god for that lol saved me a lot ov messin ha

[garyc]

depending which rollers but a decent class 2 autograss nova, basically a blueprinted 1300, decked block and 60-80 thou off the head, with +40 pistons (and running through a 32mm restrictor) is putting out 75-80 at the wheels.

[paul burney]

So if am running at 64 at the wheels is that about right or not lol

[Royston]

Does it definitely have a Emen X17 cam? or has it been changed?

The cam was an option, not std

My other Sport has a std cam in it

No cam would make it about right, is it standard spec otherwise

[paul burney]

What is the easiest way of finding out is there any markings I can see etc etc

[Royston]

Mark the distrubutor location for timing, remove the distributor, one nut, 13mm spanner, see what is stamped/engraved on the end e.g. enem X17, kc AST2, etc

[paul burney]

Roy ur a star saved me so much messing if it does have the x17 cam what BHP should I be looking for

[Royston]

Assuming it is in decent condition, not worn, speculatively 70/75hp at the wheels as stated above 93hp at the flywheel.

But you ain't getting that at the moment! so would guess it is a std SR cam

[paul burney]

Cheers for the help Roy
