it would be good to see you use some smaller trim turbines Stao, your current range all have larger trims than their garrett equivilent which some of them are already on the big side (GT30 v G3 wheel) Dave it says 15psi actuator and 2.2 bar limit lol
-
that looks to be a highflow with stock housings, prepared by sir kando himself. looks to be a new release, nobody has one yet. i would be interested to see how that performs against the staple GCG or hypergear. Price wise its in line with the hypergear but seems to have very different specs. A T3 stage 3 rear wheel with a 20G sized compressor. The T3 stage 3 is similar in trim to the TD06SL2 turbine but is larger in inducer diameter. Would be interested to see the results.

lol cant believe they are playing breaking benjamin at the drags. thats awesome. landscribble who tuned the car? the run looks/sounds indicative of the power your trap suggests.
-
Back to back on the same car you mean? It would have to be a fairly drastic time difference though I think. Last time I was at the drags I was watching 8s fail off the line and do a 14, then link it up right and do a low 12. Traps both runs within 1 or 2mph.
-
I'll be sure to report back with feedback on my hoses in due course.
-
Provided you squeeze it down the whole run that is correct.
-
Ive also always been wary of bolt on bolt off tests that crop up. Surely charge temp and turbine efficiency alone would leave a few degrees in the lurch between models.. Otherwise what is the point of spending an absolute packet on tuning? Time to jet up our cabys and change the chip in our MSD. Get yourself a dyno Lith Once you have a place to sit and tune which belongs to you the customers will start lining up.
-
its definitely a balance between spring rate and damper control, but thats not to say you wont be able to improve on it without changing the springs. keep the car focused on its primary use and work with with youve got for the rest. for me im building my car for mostly circuit and hill climbs, so the suspension is mostly thought out for that but i will be fiddling with settings to try and do my best at the strip. things i can change then change back.

Not topic specific but I have recently built my motor and opted to go with the ASI hoses off ebay (similar to autobahn88) they set me back next to nothing and the kit was both good quality and came with every hose that it should have. Fitment was perfect, I just needed to buy worm drive clamps as the silicon hoses are a little fatter. The silicon will outlive the stock rubber hoses without the fact they are probably half perished from sitting on the shelf for nearly 2 decades. http://www.ebay.com.au/itm/skyline-R33-R34-GTR-RB26DET-silicone-heater-hose-kit-/280887337908?pt=AU_Car_Parts_Accessories&hash=item416630a3b4&_uhb=1#ht_1240wt_1088

having the dampers set all the way down isnt necessarily helping. thats not how suspension actually works. you want the car to absorb some part of the power and to squat plus stay squatted. having your damper set to zero is just gonna let the car bounce and rob you of power off the line whilst inducing wheelspin. turn the dampers back up until you can feel the car solidly squat and stay down on a decent launch. A nice firm squat, not a free fall to the floor.
-
Need to track down a weighbridge. Have a full tank and nothing extra in the car that you wouldnt have when your at the drags.
-
have you ever weighed your car? knowing the correct weight you will be able to calculate the estimated power
-
YAY I like being correct.

Neg, made 234. The 228 was just @ 6000 revs. As noted it made 227 @ 5000 revs the day before, with 5psi less boost and on the run in tune.That was on the 17/01/13 with a max of 29, the very next day the weather was 40+ all day long. Workshop temps were over 50 said the tuner. http://www.elderswea...t=site&lc=66062 Roy while I do appreciate the difference in motor, I still am not sure the additional in effort and cost is warranted. The core flowed into stock housings will bolt back on and go for the retune, not the 3k needed for the kando/manifold/plumbing. My dyno sheet to follow.

109mph at roughly 3000lbs = 320hp What turbo is it mate?
-
Need to consider thats the older outdated SS1, which is essentially just a 2871. The newer SS1PU is better. On the 45 degree day my car went as follows: RPM______TD06__SR SS1PU 4,000______ 135____140 5,000______228____205 6,000______245____228 Bare in mind my car made 227@5000 on the base map, on a 30 degree day with 15psi of boost (whilst running in the motor). My car has also been tuned as a brand spanking new motor that will go straight on the track, and was tuned in 45 degree heat. So there is a lot more left in it. On my current tune your car is ahead. When the time comes for a proper full power tune I doubt I will go backwards from the base maps 227@5k. Mine is a stock position turbo, running the stock manifold and an internal gate. It costed sub 1K and bolted straight on where a stock turbo would have otherwise fit.
-
Heres the graph for the older spec SS1 turbo: http://www.digi-hardware.com/images/dynosheets/atr43/atr43ss1/r32/rb20det225rwkw.jpg He could easily get the VG30 turbo rebuilt into the SS1PU specs (birds also got this core put into stock housings). Mine stacks on really well between 4 and 7 on my SR even without VCT, and so Im confident it will be much of a muchness on an RB20.
-
For the effort you are much better off sending your blown vg30 item to hypergear. 900 later and it will bolt straight back on, just get it retuned and party on. by the time you set up your gate etc you will have put a hole in more than double the money. The differences in performance is anyone's guess but most likely not worth it.
-
I am waiting for him to clarify if he means low mount or stock manifold. Nobody else on the forum has that result, squillions have tried.
-
Proof please? Photos and dyno sheets, as there are none on this forum.
-
Cannot be side mounted with 4" comp cover. Stock manifold wont pump out that power either. Need a highmount to match the results. Nobody in this thread has said they bought a T04 Kando, so I dont think anyone will have results for you either Frosty.
-
Thats not exactly how it works. Boost that it will run is an indication of the motor and compressors efficiency. That being said you will actually not know how much boost it needs until you tune it. Once its on the dyno getting tuned the point where it starts to ping or stops making power will be where you stop. Dont worry about what it needed on someone elses motor etc either, as it may want to run a different amount of boost on yours. So go get it tuned and let them boost it to the right level on their own.

Potential Of Stock 33 Gtst Brakes
GTScotT replied to eightsixboy's topic in Suspension, braking, tyres and drivetrain
Ive had some feedback that DS2500s are pretty ordinary on the street, I would go the A1RM for something more of a club warrior than dedicated track. -
I should note that in todays milder weather conditions the car was faster on 14psi than it was yesterday on 20 I havent had a chance to turn the wick back up to 20 again but will in the not so distant future. Weeeeeee skating in 3rd in a reasonably set up car is scary lol
-
Thanks for the feedback guys, its just my luck to have it tuned on the hottest day recorded since 1930 lol I got to have a little play once I got it back to the area and I can say it is fast. Its got a solid powerband from 4000-7000, a good 3k of fat power. I do think I might want to get it touched up on a cooler day though, there are a couple of areas that I feel could be improved. Having let a friend drive the car first was a mistake lol, the stock 3.7 diff ratio can really make the car feel dead if your expecting it to boost from 1700. Once I jumped in for a hoot having a reasonable idea of keeping the thing on the boil made it a completely different animal all together. Unigroup said the car gave them zero hassle, went on the dyno and tuned right up. They were very impressed with the way the setup behaved and said the motor itself was possibly the best built motor they have had come through there in a long while. Ill attach the graph here for all to see.
