Anybody running this turbo? I'm in the process of putting one on my notch but have yet to hear any reviews on this thing. Post hp/tq and et/mph if you have any experience with the 67mm

My combo:

1990 mustang 5.0L coupe. Car previously went [email protected] with the t5 iron gt40's and spray. I'm hoping to be a full second faster at minimum

Stock shortblock Trick flow stage 1 cam Aluminium gt40x head t moss ported gt40 lower with a down's box upper 255 warbro pump and 42lb injectors

Stock rebuild c4 automatic trans go shift kit 2500and stall (probably too tight but it was lying around) 3.55 gears and a 275/60/15

On3 turbo kit On3 67mm ball bearing turbo upgrade (.81AR) single 3in exhaust dumped into a dynomax ultraflow

Complete upr tubular front suspension & coilovers 14in 175lb springs Strange 10 ways all 4 corners stock rear springs (1 coil cut) Upr adjustable uppers/lowers

Will be tuned on a megasquirt

What RPM does it start to spool at? What RPM do you see full boost at? And how much boost are you running?

Do you think the quick spooling is more likely because you have a larger 331CI motor and its pushing a lot more air than a 281CI or a 302CI and not so much the turbo? (your car should spool a 67mm turbo a lot quicker than a 4.6-5.0L)

Thats cool the ON3 Turbo has water passages, i did not know that.

honestly idk but either you get a 67 ball bearing or a 70 journal bearing turbo i think in the end the 67 is a better choice! ball bearing should spool faster then the journal anyway! also i only have heat wrap on down pipe and my under hood temps went down in half it felt like after we hooked up the water ways!

How did you route your water connection from the turbo?

honestly with the journal bearing i see them both spool up about the same on the dyno on the 5.0 and 4.6 cars.. and the mod motor was a ####ty first gen kit. cant wait to see what it does with a 5.4 and the forwarding facing stuff
