Some say Zeds are laggy. Compared to what? I don't think so. SAU Dyno Day at UAS on Saturday 48 Skylines plus our Zed Slot Car and Top Secret GTR and guess which made the most power? To think some like Martin Donnan who writes for Zoom and HPI says zeds are laggy. I am going to send him this lot. The GTR with the 371rwkw has GTRS Turbo's, cams etc whilst our Top Secret GTR has Trust T88. The T88 38G turbo kit with manifolds etc would cost not much less than my whole motor. Stickers don't make power. Mine actually did two 427rwkw runs first thing in the morning then at the very end.
Z would have to be one of the least laggy turbo cars... given the twin turbo set-up. Those dynos dont suprise me at all. Who would say that rubbish? Also, if the Z had 4wd, the gtr would be in alot of trouble
Sold The motor that made 456 rwkw we sold with Autronic and CDI, radiator and header tank, exhaust, oil cooler, catch can, etc We then decided to build a cheap motor that still made big power with what we have learnt over the years. We have not finished with it and probably make similar power. Reason why Zeds are less laggy is 3 litre for a start, longer rods means more torque, much longer runners means more bottom end but less to end. GTR's rev harder though. I would rather more usable power and down low, less strain on the most damaging thing in an engine other than detonation and that is big revs which GTR's need to make power. Compare the usable power considering at drags we have rev limiter at 8500rpm. Circuit racing and drift has power when you want it don't need to drop the clutch.
REVS I would have thought the rb26 would have more torque being a straight 6 and the z more revs... there goes my train of thought ..:wacko:
Nice chart JP Hey John do you have 2RISMO (Adrian) dyno chart for his R33 there to post? That power band when the nitros hits up is crazy!:wacko: Alot of beer talk and stuff after that day, my zed beat most liners on only 15psi.
that is some amazing info to add to the inventory of why zeds are better in every way over any car i seem to look at. not like i'm gonna sell my baby.
There are a LOT of fast skylines out there though, running 10's and 11's quite easily... so at the end of the day the dyno is just a figure. Yes the AWD does help, but that is just how it is, both cars have their pros and cons. Look at the guys in jap, they have some almost street trimmed GTST and GTR's running 8 and 9 sec 1/4m!!
That's right. To be honest that graph doesn't prove much Not to take anything away from your achievements JP, but they both have the same amount of useable revs and almost identical area under the curve. The Z graph would look like it has to rev high compared to a huge displacemnt V8 and the GTR makes it's power at low revs compared to a formula one car. It's all relative. If the GTR could still only rev to 7000 it would be a different story.
Re: dosn't prove much Did I miss something, I was at this Skyline event and witnessed the dyno runs of some high moded liners. The only liner that came on harder than the VGDE30TT was a nitro burner R33 gtst but peaked at 265rwkw @ 6400rpm. The Top secret R33 was as laggy as and did very little until about 6200rpm, by that stage the zed was almost at peak power. A heap more user friendly than having to wait until 6000+ for power I think. Even the SAU members made this comment, and they give very little away. Still it was a fun day showing up a lot of skylines in my barge boat.
I think I came across a bit more harsh than I meant to You are 100% correct that the Z would be more user friendly on the street. Also, obviously it is better for engine longevity to use lower rpm but if you compare the area under the curve between the UAS Z32 and the Top Secret GTR they are the same, so with correct gearing they would be just as useful as each other on a race track.
Hey Ports I saw Adrians dyno sheet at Bezerkly yesterday , makes me smile just thinking about it!! I havent watched a dyno run with Nos used so that curve (wall would be a better description) blew me away! If Adrians does that just imagine what beery's (RNMENC) is going to do :thumbsup::thumbsup: Thats a superb car Not looking good for our drags tomorrow night
Am I missing something Maklar same on the race track? You obviously have never been on the race track. Circuit I am mainly talking about which I assume you are, saying track. Even though most of the time you are between 5 and 8,000 rpm there are a lot of corners much lower revs. Like F1 the other night revs down the straight bits go from 17 to 19,000rpm button some hair pins they got down to around 6,000 rpm. This is without traffic or having a moment or miss gear etc. So end up low in the revs circuit at any time and little power as revs build and precious seconds lost. Also we could have and will run it higher in the revs although power is not going up much at all and may plateau off but if we did rev to 8500 like we do at the drags then there is a LOT more useable power. Maybe I should not have said anything or say not sure if my zed is laggy or GTR. Debating things is cool though just always an angle and different ideas bordering on off track ideas and thinking.
Isn;t it the other way around I thought the V configuration makes more torque and the inline configuration revs higher?
The new F1 V8's were revving to 19000rpm on Sunday ... Imagine then what an in-line F1 could do! I guess there's a lot more to it than that though, don't think an in-line motor has been used in F1 since ......... I dunno!
