hey everyone I'm wondering if my rb20 amf will be up to the task my mods are

Td06h-20g turbo 8 cm housing

Turbosmart external gate (17 psi)

Stainless highmount

32gtr intercooler

550 denzo injectors

3 inch exhaust rsr

K&n pod filter in box

Will be getting a tune done just want to know what else I need before I get it done

RB20/RB25 AFMs max out at about 200kw (give or take 10kw depending if your willing to take the risk of tuning it outside of it's resolution), if your target is 200kw+ then you will need a Z32 AFM

They are supposed to be about the same as RB25 ones which means that they hit max volts at around 200rwkW......but the common wisdom is that they run out on RB20s at about 180rwkW or so. Mine is about 170rwkW and was sitting on 4.9v or something at max power.

Just had my rb20 tuned with similar mods but standard injectors, 14psi and made only 188rwkw. My next move is obviously z32 afm and some sards

Then we both crack 200 easy i would think

Correct me if im wrong please, but if it is a colder day or cold night doesnt your afm have more chance of maxing out / reaching maxing voltage compared to if it was a hot day?

    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !  
    • Thanks, will do that.  Thankfully they still feel great.
    • Yeah man, absolutely. You can try pushing me all the way in swapping the R34 for an E9x M3 
    • It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
