just got back from RR
Turbo Mini Forums

141,2 Bannanas and 157 curly wurleys at 12pounds of boost

had a few issues and run out of time on my session

the 8psi 1 year old actuator would not hold boost over 6psi so had to bleed up to 12 .... not ideal

so a new actuator is on the cards

and the trailer spat a wheel off on the way home

well done mate

Nice, good for 12psi. What engine spec ? or is it secret ? lol.

Sound magic, worth all the hard work. Well done mate.

A man without a project is like a like a woman without a shopping list.

very good result from 12psi neil. Looking forward to seeing this car. :)

Well done mate glad you got it sorted, and pleased for you that the initial smoking problem was a relatively easy fix and nothing that major!

For the actuator, look on ebay for a sierra cosworth 4x4 one, the cossie boys all change them for upgraded ones so they are dirt cheap, and give around the 10psi mark depending on how much preload you wind on. They are a direct fit onto a mini type T3.

good stuff, im so jealous of you guys with massive power figures, makes me feel a little inadequate...

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

good stuff matey. more to come no doubt

hopefully Iain

its a blinding starting point to be honest and if i can get the trailer fixed by sat i will be getting some practice in at USC

well done neil, thats a bonzer amount of torque ,how was the curve ,?? a bit better than the big jump at 4500 you had b4?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

torque is fine just breaks your wrists when it comes in


i will pop over tomorrow evening with the flywheel if thats ok and show you the graph max torque is at 3600 rpm

good work

i take it the trailer didnt cause any damage?

well done wolfie

loads more to come!

any chance of showing us the power graph ??

nice one mate well done.

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?

well done mate

Team Racing

my graph



will need to get back to sre and finish the mapping as i did not book in the car long enough and it drops power to early at 6200,
have to say thou i am happy with the service that Neil Slark provided, a very accomadating chap who was very interested in the engines welfare and was very carefull in how he treated my car and he did not call me a wanker and slam the phone down .... bonus lol
SRE will be in the recommended thread soon

clutch slip?? 15 bhp losses ,thats very low , its normally 20 to 30 bhp niel.well done.

I have often wondered myself what the -31 means, no one has ever been able to explain it properly.

The -31 however is an upgrade for the Cosworth boys from the standard item, so I am guessing it must somehow be superior to the standard item. The standard Sierra Cosworth actuator is good for around 10psi on the Sierras.
Mine cost about £8 if I remember rightly?

I'll try to get the lower one then...

i think i vaguely remember that the suffix eg -31 ,relates to inches of mercury in boost ,so 31 would be around 15 ...but this may well be total drivel and tosh.

By jove I think he has got it!

Just having a quick Goooooogle shows the conversion factor from PSI to In Hg to be 2.037, therefore 31 In Hg equals a shade over 15psi!

Good stuff Robert!

Vegard, as I said before, leave the cossie boys to their -31's, they always seem to go for good money, go for the standard ones that they don't want any more!
