I took the turbo mini out today for a spin as its a nice day.

had a twiddle of my knob...then found myself at 19.5 psi

and bloody hell that's fast!!

it feels as though theres more to come...afrs were 12.5 on full load, with a compression ratio of around 8:1 there possibly could be...

need to get it booked in at the rollers for a power run.

last time on this engine it made 160.1 bhp at 13psi.

felt like warp speed today!!!

yes it will steve, need to get it booked in. think the last run was done at maybe 10 degrees ambient, the 20 degrees that we are seeing now wont help with power

I have no 'dyno' figures for mine but my calcs seem realistic
I found over 25psi to not make any difference on mine needed no extra fuel and just seemed to push up iats
Imo 15-20 psi is where I felt comfortable
around 20 and above would usually net lots of wheel spin if just planted and left to get on with it open xpin diff lots of -ve camber next to no ride hight and a008s dont help the traction though

These are my findings with the hole psi thing.

10 psi = fun on the road
15 psi = even more fun
18psi = made it wheel spin on the RR at 188bhp
20 psi = on the strip twisted drive shafts, killed pistons, lots of head gaskets, also a valve.
30 psi = on the strip killed two pistons, cracked a head, head gasket, and twisted the output shaft on the diff.

So what I am greeting at here,

"Go big, or Go home" " Go to big and your going home on an AA truck"

I have started posting on Instagram also my name on there is turbomk1golf

Nothing is impossible it just costs more and takes longer.

We put 2 bar into the upside down skip - pistons, head and gasket all good. Thrusts, crank thrust face and second gear less good... i.e. ruined.

after reading this, i will stick to 14psi. i was getting 180bhp at 14psi and that is enough for any mini like mine, however if you have it all set up correctly and a diff etc then maybe 200ponies :)

I,v told the story on here before, but when an actuator line split I was getting 25psi + and the A35 saw off a 2 litre BMW big time from a standing start.
The engine did make some funny noises though !
