1/4mile in 13.2sec @ 111 terminal on 15psi

oky doky,,, sorry for taking so long to report back to you all,,, i don`t really get much time to work on this thing amongst all the "Normall" mini customers, but still--->

it`s all apart & it`s only cracked the ring "Lands" on the pistons,,, All the rings are actually still fine (altho i obviously won`t be using them again, except maybe on a 2nd hand sh!tter roady donk of my own one day, so i`ll keep them anyways)

But i`m a bit happier now,,, no bore problems, the bearings are sweet,,, the crank is just ever soooo nice & shiney smooth,,,, it`s all good `cept Pistonies

so,,, i`ve been chasing around for some "You-Beauty" Forged race pistons, maybe JEs or Ross or Arias whatever comes along asap

I`ve allready got the double grey comp clutch diaph & super duty AP comp race c/plate

I have to sort the clutch master cyl & the hose, (feels a bit dodgey so i`ll make sure it`s all sweet while the donk is out),,, there is some stoopid weired horrible home made gearshift mount fitted that sux bad to get the gears , so i`ll be sorting that while i`m at it too

But apart from all that we`re back in business


I can`t believe the rings weren`t broken tho,,, wild

What pistons were they Matt?

In the 13's at last!.. Just

They`re JP brand (made here in Aust),,, my dad designed them years ago in conjunction with old Frank that used to work there (since died) & they`re really really strong for N/A road & full race applications & have been proven well worthy for years & years,,, It`s really not the pistons fault at all,, 35 deg ign timing with lots of boost & my dumb arse right foot made it all go yukky.... most of the turbo gurus that i`ve spoken to said the same thing

35° ,
you can use whatever brand of pistons , u'll kiss them

hee hee,,, kissing them is just first base isn`t it??? 2nd base would be playing with their tits,,,, so I`m pretty sure i hit 3rd base with them

I used to call them "Indestructo pistons" cause you just couldn`t break them, no matter how hard you tried,,, I`ve never actually seen or heard of anyone breaking them, EVER...till now ah well,,, can`t call them that anymore now can i?

i think youd kill any piston with that combo of timing and boost matt..stick some more of the same in ,and try 15 degrees in stead .

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

yeah thanks guys, in hindsight i actually should have made sure & checked the timing myself before i even thought of driving it to the dyno, but Ian (my so called computer guru tuner specialist) at the lap top "Playing around" with all sorts of whatever, i totally expected that he`d set a max ign at about 20deg allready,,, so the plan was to put it on a tilt tray truck & carry it to the dyno,,, so after he left to go have dinner & meet me at the dyno later, i decided that i`d just drive it there... little did i know that he had "NOT" set a "decent" ign max,,, he didn`t think to bother till we got it on the rollers, cause it wasn`t meant to be driven hard till then,,, so it really is all my fault , i take "ALL" the blame... i`d like to blame him totally instead but it still wouldn`t make me feel any better nor would that fix the pistons

But in saying all that,,, i`ve realised that we will definately want to "Play" a little harder later on, so more boost is on the cards soon & i do suspect that the very best pistons that i can get would be sensible at this stage

Now that i`ve had a taste of some "Decent" Boost, i want some more
