P.E.T Modifications have an in-house chassis dyno and they're in thomastown off Dalton Rd.

call dennis on 9464-4225.

if i was you i'd be taking the car to somewhere else just to do a dyno power run, as if i had spent my hard earned $$$ and changed to a turbo that can take 18psi on a rb20 and then got less power than a standard rb20 at 14psi it would make me think "WTF"...

It actually doesn't make less power than standard. He didn't do a rolling stop (out of gear) so you can't tell what drive line and dyno losses it was getting. We'll find out how good a job he did at tuning when I take it over to P.E.T. at tommo

just take it to MAZTECH they are good with RB's

106rwkw at 5000rpm at 16psi apparently this is as much as a hotted up 5ltr HSV (cam exhaust, cold air) on his dyno.  It was run in 5th gear.

This is a crap figure so you know I am not lying.  There was no fan so the IC wasn't working (does that make sense.)

I have also had fitted a BOV that is set to 16.5psi, the turbo I got is not ceramic so it will go to 18psi.  

Does anyone have a comment on how what dyno figures really mean.....?

I wouldn't be at all happy with that power figure!! Stock FJ makes 110rkw!!! Mate of mine with an RB20 made 197rwkw with just a VG30 turbo, FMIC and exhuast, not tuned or anything..Did u end up getting another power run elsewhere or???

[rsx84]

at the wheels a standard r32 gtst should make 115-117kws, with a 3" full exhaust that will get around 15kw extra then add a good fmic for another 10-15kw remap the ECU to run 14psi and that will leave you with 150-160rwkw

[Doctor 30]

That is exactly what I thought. I should have around 220fwkw at 15-16psi with the mods I've got.

didn't get around running it on a dyno but I found a leak. I used permatek type 3 around the leak but I haven't run it hard yet. I'll repost when I eventually get around to dynoing again.

Doing it the way he did doesnt sound at all dodgy to me, much hbetter to tune it for those conditions, then you can be sure it wont expire in summer.

Intercooler is just a heat sink in any case, even without a fan it should be ok for a single run because while the car is idling before you run its not getting any heat transferred to it so it starts cool

My stock boost FJ20 made 124 in shootout mode

how does the VG30 turbo rate on an RB25? they are steel wheel/shaft right?

whats the difference in A/R to the RB25 turbo?

Im not 100% sure on the size differences compared with the RB25 turbo, i do know that u can get two types of VG30 turbo though, one's ball bearing the other is bush bearing...Most VGs are ceramic wheel whilst u may just find one or a few that are steel, they exist but are rare as...
