SO many variables. Believe it or not other cars have had a much harsher life than others.

Correct........you take 2 cars with identical mods yet one has a fresh motor while the other is lacking compression with crappy plugs and I guarantee a difference of at least 20 or 30kw.

How much effect does the ramp rate have on the over all figure. it would be the same difference as doing the run in a lower gear because that is effectively what you are doing by altering the load. I.e. there wouldn't be 10% difference in a 200kw car due to RR more like 2 or 3.

Also this engine had extremely good compression, i posted the figures up in the wasteland when i did the test because I wasn't sure what the range factory range was, but they were all around 169 mark with very little difference between them

Actually sorry steve have to jump in here noone's actually said he didn't make the reading there just questioning the equipment they used to get the reading!

comprehension i never once said he didnt make that figure just what were the dyno settings was what i was implying

remember people its just a number.

yeah but to some it seems figures are more important than where their car is at!

i only pulled 185kw with a pfc (got a restricting exhaust) but some how i still manage to be right next to my mates skylines even though they have more power! as long as i feel the result i'm happy

The more power the car has the more dramatic the power difference is going to be when you vary to ramp rate. Ovrtym33's R33 made 325roundaboutrwkw on moderatly high ramp rate which was around 270 i think. Due to the fact we had to dial out alot of wheel spin on the dyno. On a more modest / realistic ramp rate the car would probably make around 340-350rwkw....however the same ramp rate differences on a 200rwkw R33 would be around 10rwkw difference. not too much but enought to make a customer drive out happier lol.

well the car was actually on the dyno to find an ignition fault which turned out to be the No. 2 coil pack. The figure was just a bonus, i told Zac that he wouldn't make 200 until they played with the SAFC but you never know, that's the thing with playing cars.

He's now giving me shit about how much effort i put into my CA to get 16 kw more :) . But I'm only a decent actuator away from 235.

Yep, but that's what you get when you try and 18 psi through a 9 psi actuator.

I only put 2mm of preload on it though so I might try a little bit more and see if that works but i suspect it'll just make it spike higher and then drop to the same point. I'll by a 13.8psi actuator and bring that along when it goes on the dyno next.

hey im in the same boat, took my car to turbo tune bout 6months back, i hav a fmic, hks cat back, walbro 500hp pump, pod filter and running 11psi flat (earthed out solenoid). My car got a read out of 221.1rwkw. My engine is a bit weird tho you cant run the pod straight off the airflow meter cause my car will just flood up wen hitting boost. i need an extra bit of pipe on the end and then it runs sweet, turbo tune said they hav never encountered a problem like that

dynos are only good for tuning. and bragging rights :P my car made 235rwkw on tilbrooks dyno with standard ecu and turbo running 13 psi.

thats way too high..... since then the car has had a haltech e11v2 installed at boostworx and runs the same boost but made 197 rwkw on boostworx dyno :P .... that being said the car is heaps more responsive and pulls heaps harder.....

Your right that is way to high but that's Tilbrooks dyno for you.

      Cleaning my wheels 😍

      By PranK · Posted

      A little follow up here on the ceramic coating.  We've had storms galore here and I've done a few ks, enough to gross them up  Consensus is that they didn't get as dirty as usual, the coating definitely repelled a little of the dirt and I think they kinda snowball. They get a little dirty and then they get dirty faster which makes sense. Cleaning them regularly would allow them to protect better.  Cleaning was a breeze. I tried first to just hose them off which, unsurprisingly, did nothing. But, making the wheels wet and then just wiping them over with a used but clean microfibre cloth was all that was required. I didn't need any cleaner at all, just water and a cloth. The wheels look amazing again.

      Gave her a nice wash today and took extra time to clean off the tree sap and tar and crap. We have a usable garage now so she'll stay cleaner longer. Took a few snaps in some nice light afterwards.

      Duncan's V37.......race car?

      OK, solid mount Z1 diff brace is in, pretty straightforward, it picks up 3 diff hat bolts and ties them to 2 support bolts on the subframe. Pretty sure someone else on here said they had reduced axle tramp with this but mine was already pretty good for smooth wheelspin, and still is....will see you this goes over time and whether I end up with a broken rear diff hat

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...
