SimonR32 Posted May 17, 2007 Share Posted May 17, 2007 12.8 on r-comps and 12.9 on genuine street tyres plus i ran a 1.8 flat 60 foot on street tyres but clutch stuck to flywheel and couldnt smash box into 3rd haha that was with enough power to run over 113mph (the run before), low 12 went begging! i'll race u in the gtr instead hehe Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/66/#findComment-3125334 Share on other sites More sharing options...

Roy Posted May 19, 2007 Share Posted May 19, 2007 Hehehe. Std RB20s pulling good numbers and good times. And legend finally gets his 20 back on the road. Great stuff peter. I cant imagine how much fun that car must be to drive. How is it for traction in top of 2nd and 3rd gear? What boost? Does the head work help it make power? Your thoughts? LOL..i want to throw the HKS manifold and 3076 on. 20G just wont make the top end i need to scare the big boys at Phillip Island and Sandown Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/66/#findComment-3128900 Share on other sites More sharing options...

Roy Posted May 19, 2007 Share Posted May 19, 2007 hehe...there are still a few ppl down here that attribute the speed of my car this year to a cheater spec motor. Its just that for the first time in a good many years i have a working diff, good rubber and a tuner that knows what he is doing, so not having to drive around too many problems.

BlueRB240 Posted May 19, 2007 Share Posted May 19, 2007 you'll run into the 12's, but a low 12 required stock rear strutts and coils, i ended up with positive camber on the back when we put them in which sqaured the tyres out on the launch.and you'll need micky thompson e/t's my 13.1 in street trim was on 20 psi aswell, when i up'd it to 24 i couldnt get it to hook up till 4th the 16c rear isnt THAT bad hahaha, i see full boost 24psi by 4700. Do you run ARP head studs and aftermarket headgasket? I'm just wondering how far I can go with the boost on my RB20. I was planning on a max of 25psi but if your doing that on the stock head studs I might just push for 28psi. I'm running the head studs, Tomie headgasket, sard 800cc injectors, Prescion SC61 turbo, PFC, Tomie 270 cams, rips intake ect. I think I might need to run alot of boost before that turbo is happy. I just hope she will hold the PSI and I won't try to blow the motor.

legend01 Posted May 19, 2007 Share Posted May 19, 2007 Hey guys Just back from the dyno day ,had issues with fuel leaning out at higher rpm but was pretty impressed with what it made by 5300rpm will post graph Roy ,its great to be driving it again feels awesome pulls like a train but its still a new engine it will get better as it beds in some more its got like 1600k's on it now so there lots of playing to go.On high boost what traction and high boost is 23psi I'll try to answer your's and Johns q about the head work and its value at once .With the old bottom end I never had any trouble with high rpm's leaning out it could also be crank and bigger bore that helping this but alot more air flow will cause it to so the 1mm oversize valves and I spent a bit of time doing the ports again in my opinion has help with power but I think its helped more along the lines of torque its feels heaps better hills that i'd drop down a gear b4 now cruise over it top no trouble but more than that i think its reduced lag time a fair bit you'll see it in the dyno graph I got today as I didn't get one when I got it tuned 4got was to stocked with it toping 300rwkw Butters it would if I had 82mm pistons but mine are only 40thou oversize 79mm standard is 78mm I'm thinking about doing a post on this rebuild with all information I have as took heaps of pic's during build but thats for a latter time his todays dyno graph you can see where his backed of at 5300rpm here but here is where you can see where full boost has come in all the work I did with the flow honing has paid of and the head work has helped this as well usable power Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/66/#findComment-3129315 Share on other sites More sharing options...
