What psi boost / bhp are you running
Turbo Mini Forums

It would be interesting to see the differnce in boost levels and how they translate to horses so
What psi boost / bhp are you running??
I'm running...
1293cc, T3 turbo, MED 10cc at .020, no intercooler

8psi / 122bhp

Edited by boostjunkie on 2nd May, 2013.

Confessed addiction to everything mini

259bhp @ 26psi
ran over 36psi on the track, not got a rolling road figure for this boost

Team www.sheepspeed.com Racing

Surely it would also be useful to mention a general spec as well, to help differentiate between different size engines

@ last rolling road.

132.4bhp 140ft.lbs @ 13psi of boost with a super rich mixture (operator reckoned I would pick up quite a bit of power just by leaning it off!).

+40 10cc Omega's, Mildly ported head, phase 2 cam, 2wd cossie intercooler.

If something is worth doing, it's worth doing half of.

203 @ 20psi

Edit: spec added - 1310cc forged accralite, std crank and rods, Benross head, GT172, phase 2 cam.

In the 13's at last!.. Just

137bhp on 14psi. Home built with used pistons,Turbophil head, used MG Metro cam GT1752.

Goes a lot better when I bleed it to 18psi but no idea how much that adds in hp terms.

Comparable to mine then Dave (I'm on a T3 though)

If something is worth doing, it's worth doing half of.

125 hp @6k with 132 ft tqe running .7 bar which is about 10psi

- 1293
- T2
- std head with chambers opened, AE 21251 pistons.
- around 9.1:1 with i/c

169bhp @ 16.5psi

1293, T2 hybrid, 8.6CR-1, MED FIS head 36x32, Ph2 cam

Class C 3rd Place Avon 2011 14.18 @101mph

14psi 1293cc 5 port head by turbophill, single turbo carb, renault t2 turbo - 170bhp and 155lbf-ft (8.2:1 CR)

About the same spec/boost/power as theoneyedlizard,plus 60bhp of NOS on the strip.

'Where does the engine go?'

Benross motor is 1380 5 porter hybrid T3 18psi boost nice internals etc.... 234hp
this was done many years ago.

heres one of my friends 1380 5 porter Benross head trick internals gt17 16.5psi
of boost ....... 186.3hp and 190 ft pounds torque.

its realy not the big figures as most of us know its how the car feels and drives, i think around 120 to 130 hp in a mini is just about right anything else is insane and dangerouse!

Flippin eck. Some seriously high figures there for such a small CC. Im impressed and excited at whats possible with these engines.

1310cc gt17 smallish fiesta diesel intercooler.





running no fan on ic ,ic warm to touch .

and 15 degrees timing , id expect 200bhp at 16psi on more timing and cooler ic .

clutch did not slip on rr ,when racing it did...

bhp at 12 psi was 168
bhp at 15 psi was 183
bhp at 16 psi was 188.

also 21 psi netted 248bhp.on a different dyno .

importantly ..i have over 100lbs/ft from 2800 rpm ,as steve says , low end trq is important for driveablilty .look for dyno graphs that go down to 2500rpm to see that sort of detail and understand the felxibilty of the overall design .

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

1275, T3, head 35,7x31, Ph2 cam, without intercooler.

101 bhp at 0,3 bar

jim if you are trying to partake the water "dont bother" ..... its just not you! ............. are you going to sell yours ? .........

It's been on eBay before, I'd be willing to sell for the right price. But I'd also pay a lot of cash to get 230 at 18psi from my 16v twink

Team www.sheepspeed.com Racing

jim if you on mr baldwins rollers you will maybe you need to try a little more

EDIT: i am not getting drawn into a bun fight, as this has ruined many forums, and turbominis isnt going to be one of them which nearl happend in the past with other members who have left and never returned to the sad loss of their knowlage and experience

Edited by BENROSS on 2nd May, 2013.

some serious power there.

my last engine, 1275, johnnys turbo phil head, standard t3 etc, 2wd cossie intercooler, sw5, 10psi 130 bhp, 130 pounds of torque.

new 1380 engine now in and running, same head, phase 2 cam etc, actuator set at 16 psi ish. hybrid t3, ported manifolds etc... cr 8.1:1....will have to wait and see!!

Mine was 200 bhp and 203 lb/ft @ 20psi

1293 cc, 11cc 21253's, turbo phil head, GT20, phase 2 cam.

how true that figure is I'm not sure but it did make 190hp at the TM rolling road day on 20psi when it was getting tired.

Edited by Nick on 2nd May, 2013.

HA Jim, your engines crap, lol

400 hp on only 6lbs at 4k,

well its about as credable as some figures, obviously i don't havea dyno graph for this as my pen ran out when i was drawing it,

Robert, what's the spec of your engine?

Can I propose a general rune of thumb here....

Multiply your pis by 10 to get an estimate of power output. So, 15psi should give 150bhp. Large bore 5-ports anyway.

Anymore than this you have a good-un, less and something is wrong.

My 998 has around 180 bananas with 18psi.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph
