I'm running the +80's seem ok so far. If these are the graham Russell pistons, GR offered me a free set if I melted them...

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

hope so ill be running the 1098 +60 flat tops
15-20psi and lots of compression was told they will stand up to the job just the same as gr4h4m has said
will have oil jets to help the temp tho..

time will tell but im sure they will survive well!

im sure there are many guys on here running them with success that haven posted yet

also they have been available for some time and we haven't seen any with broken lands or holes so thats good i guess have seen with the slotted ones tho from i think mini sport?

Yes a good piston

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

I use them.

I have a set of +0.040" sitting in my parts bin looking for a new home.

Not used them but plan to in a 998 plus 40 shortly.

I've got a set of the +.100"s in my 1098 but haven't run it yet.
Look and feel like very nice pistons, but as flat tops only I've been struggling with getting the compression ratio down.

He also does 68mm versions to make twink conversions easier...

Metric is for people who can't do fractions.

Twink convertion?

and Got the +40's of Paul S last night, always a pleasure meeting him top guy and pistons feel and look quality so can't moan!
