Silvia Club of NSW

sorry guys was on holiday for a week.

currently sitting at 215kw@18psi. have an issue with it not making shit loads of power. have had some people point to my cams being too large (270x9.25mm) or my custom cam gears im using (adjustable). had a problem with compressor surge but that was because gain was set too high on the boost controller (finally figured that out lol) going back for another dyno tune for some more dialing in of the cams. if this doesnt produce results im going to take it to another tuner to get the rest of the bugs ironed out.

I think that is a smart move, if he cant get some decent power shortly you have to move on to another tuner.

yeh im looking atm to take it to a workshop called Racepace down here in melbourne (down side its on the otherside of the city) but these guys specialise in GTR's 300+kw so im going to get Ben (the owner) to have a look at my cams to make sure theyre dialed in correctly as im starting to think that thats my problem and see if he can make it make some more power (hes expensive but 2 of my mates get theyre cars tuned by him and hes good).

yeah SAU seems to have alot of praise for racepace.

Racepace Motorsports did my intake and exhaust originally, which has since been slightly modified for my present turbo setup. If they can't get some decent power out of ya CA. I doubt anyone will and then it would be time to cast the boat anchor once and for all and get a real engine

depends how the cams were dialled originally. Were they set to a "true" 0 degrees then adjusted or set to 0 degrees on the cam gears and adjusted.

If you set up a set of RB26 cams and dial them properly after taking 4-5 thou off the head you will find the true TDC mark is actually 1.5 degrees or so out when setting them up witha dial guage and cam wheel.

Thats said sounds more like your tunner previous or still current is crap!

dialed the cams in ourselves, noticed there was no overlap. it now has transformed the car, it now lights up through the gears. just abit more fine tuning of them and it should make some more power, feels sooooo much better now, even took it drifting lastnight

So how much did you alter the timing by and it which direction?

No overlap??

I hate being the one to say it but this build is ridiculous

I mean honestly how many times has this thing been "fine tunned"

Dead set, I built a high end supra last month, finished it spent 5 hours on the dyno, cold start next morning customer gone and happy. WTF is your tunner doing besides taking you for a ride!!!

There is ONE tune, all done finished. No need to spend more and more time on the dyno. If he can't see a cam timming issue whist tunning his not real crash hot now is he

Sorry if you disagre but honestly thats the way it should be

maybe you should go down and tune it for him.

+1 on what he said

I think he would be hard pressed to do any worse! blind freddy could tune a car better then current tuner by the sounds of things.

lol yeh well current tunner is a rotary shop so yeh i'll be taking it to another "piston" shop (race pace) to get it tuned (if they'll touch my microtech) once i get some tomei/jun cam gears.

yeah well maybe it's normal for rotary cams not to have overlap

that'd explain why they have NFI about setting cam timing.

good luck with the next stop on the journey. hopefully this next mob will have half a clue.
