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.

    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
    • Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
