SAFC fixed my problem, dyno!!


Recommended Posts

i got an extra 130rwhp by adding safc and having the car tuned at SST, as others have said all my mods made the car slower untill it was properly tuned, from 130hp @12psi to 253hp@16psi (it also made 224@12psi) cant be happier

Redusing the gap of your plugs helps run smoother at higher revs

because the spark has less distance to jump standard is a gap of 1.1mm. Good idea to regap them if uping the boost. there probbly is a slight power gain to but the main thing I noticed was the overall smoothless of the engine at high revs.

so how do u gap ur plugs?

is it just diff plugs or wat?

i realli dun have a clue when it comes to this gappin plug thing!

and thanks for the info!

I've got Platinum 1.1's.

Yesterday I bought a little tool which basically has bits of metal in varying width, you insert this bit of metal (e.g. .08 width) in between the end of the plug and wack it(carefully) on something till the gap is narrowed.

I think you mean a Filler guage.

Hey Robo, nice power gain mate.

Your car must feel better now.

Just a silly question tho, if your car was originally running rich, by upping the boost wouldn't it pump in more air and making it a bit leaner??

Yes you are correct, but the AFM feels this and it tells the computer to richen it up more, so hence more fuel again. My original dyno graph shows the Air/Fuel ratios in the 10 and 9 to 1 which is extremely rich when the aim is for around 12 - 1. Currently im experiencing a little detonaiton at the top end of third gear which would probably is for the stock intercooler and/or lean mixture. I think i will be back on the dyno soon.

    • And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.
    • No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.
    • Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.
    • 2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.
    • I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
