How fast can a RXTX260 get on a ET127 wheel
Ok I have done the big SC thing and over it ...
The ET 127 is such such an under rated SC ...
Why bother with the little ET 127 , mainly I spend most of my riding out in the ocean which is rarely flat , so need a high boost low maintained SC ...
i had it on my RXP with no real tuning and did an easy 78 Mph ...
so the SC has 1-1.5 more boost than the X charger and 50 grams lighter ...
So my target is 78 -80 capped at 8650 reflash ...
LET THE GAMES BEGIN ......

Ok mods so far :
*ET 127 SC
*V tech 8650
* RIVA valve train upgrade
* ET rising reg
* 4 inch rear air
* IC relocation to near intake ...( no more 6ft long pipes lol)
* Solas 15/ 21
* Rear exhaust
* R&D grate
* Stock 87 nozzle
Tested once and water semi choppy and hits 8500 hard and 126ks (76.6) won't stay hooked ...
I am surprised with a Solas 15/21 how hard it hit 8500 and still pulling when it stayed hook .... Need a flat day ...
Should easy see 78 and 80 not far behind ... Lets see what it does in the flat and then may need some prop and nozzle work ...

if it was hooked up your rpm would be lower id bet, i would get 8600rpm ish out of my 15/22 in port phillip bay at around 75mph
how ever on the river where it was clam it was more like 8150 and 77-78mph

Might hook up my spare boost gauge , but don't want cut any holes ..
May just mount a plate in the glove box and remove lid when tunning .
I got 13 psi out of this charger when it was hooked up on my RXP at 8600 but every else was done ...

Ok started a good day , dam Swan River still semi choppy ...
Hit 76.4 but noticed water spray at the back over water box etc ....
Checked carbon seal and bellow boot has very min tension ... So looks like its popping at top end ...
So out with bellow boot and new one only way , it's done 100 hrs so its due ....
But even with the Solas 15/21 the ET 127 hitting 8500 ... But that could be the bellow boot leaking ...
Always next weekend ....

Nice work Al.
Anything under 80 is for sight seeing, so make sure we see 80!
