looks very flat...

i got my stock 33 dynoed (albeit in 3rd gear due to incompetent dyno operator) so yeah, its supposed to be in 4th, but in 3rd i got 182rwkw and a very steap graph compared to that 1.

going in for another run in 4th (the way its supposed to be done) next week sometime (only has a cat back atm) so i'll see how it compares to what you've got

Stock R33 @ 182rw/kw?? Doesn't sound stock to me...

My SII R33 pulled 144rw/kw (193HP) stock standard... (7psi)

3"split dump, Hiflow CAT and 3"CAT Back gave me 165rw/kw (220HP)... (8psi due to split dump)

Everything else is stock...

181HP = 135kw which is only 9kw less then mine... therefore its possible if your engine/turbo isn't in good nick..

What fuel were you running? How hot was the workshop temp? These all can easily make a big difference

Personally I would try a fresh tank of optimax/ultimate and dyno it in the morning or late afternoon...

read carefully, i said it was in 3rd gear...its supposed to be in 4th (which is what yours was done in)

another s2 R33 which has ~200rwkw was done in 3rd just to compare, and pulled 243rwkw, so it works out that mine would be roughly 140-145 if it was in 4th...

like i said, it was the dyno operators fault, so i'll be going somewhere else next week and getting it done again...only difference is now i have a cat back.

was running halfa tank of ultimate and my car was dynoed early in the morning to it was quite cold roughly 18-19 degrees im just confused why my boost dropped of sucha considerable amount practically back to standard psi

because you have a stock ECU, and it doesnt like going over 10psi..

even still, the power you got (being 9kw less than what QRI05E said he got stock) isnt really that low considering yours is the first of the series 1's being a 1993 model...where as QRI05E's is a series 2....its bound to be fresher, unless yours has had a rebuild, or his has been thrashed A LOT!

exatcly it aint dead stock why i aint to happy and i bought the car from autoworx which he freshly imported from japan with 90k on the clock i was talking to someone before and they think sumthings up with the boost because its dropping after certain amount of rpm

some 33's came with RB20DET's didnt they? and his is a 1993 model so maybe his is one of em?

No R33 came with an RB20DET from the factory you might be thinking of the RB20e that came out in the povo pack versions...

it feels great to drive i admit im just searching for power and the gusy at hyperdrive said i should get the boost checked cause if my ebc is set to 11 psi shouldnt it stay ? or is it normal that it drops back down to 7 or 8sh psi at high revs

Whats your base timing?

Maybe thats been wound back as a safe guard for running shit fuel.

You'd loose a heap of power if it wsa running less base timing than it should.

Whats your intercooler like?

Maybe check for leaks in cooler pipework, leaking BOV etc.

It all helps!

The gear does not matter dick, if you knew anything about dyno's you would know that. Its merely better to tune them in this gear as the ratios are closest to 1:1. Fact of the matter is a power run in 3rd will only move the graph left, ie at a lower speed...

Also its amazing how many "happy" dyno's are around and how many "supurb" results happen.

Sammie

I would look into why your getting a low result, maybe a restriction, drop the exhaust after a run on the same dyno and compare, there may also be other factors that you can try.

how can you say that?

how can a stock 33 GTS-T make 182rwkw when they are 187 at the fly. its not possible. and the car was bone stock.

again, how can my mates 200rwkw (in 4th) R33 make 243rwkw in 3rd?

well my car was on the same dyno as dezz's... and the result i got is consistant with results on other dynos... so unless the operator was doing something dodgy with dezz.... the dyno seems pretty accurate to me...... but yeah his car is 100% stock....

hmm guys this is real hard to explain but went to see aguy i knew had a look at the dyno sheet and looked under the bonnet for leaks etc he looked at the stock bov and saw that it wasnt blocked cause i hav after market bov connected near the pod he put some tubing on the end of it and connected it to another tubing line which is connected to the throttle body sorry im not good with motors but as i was saying i drove it and this time it actually felt like it was boosted however hit 1 bar so i let off straight away he turned my ebc off and i drove it was hitting .8 bar and felt much much better i could tell because the bov was much louder and could hear the pressure releasing alot more however in 3rd gear it almost hits 1 bar which i was told is veryvery unsafe for my car so i just putted my way home any ideas ?

      I remember the days when E85 was priced in according to the $ per km outcome. Sure E85 was about 35% cheaper, but you also lost about 35% range... now it's fked..

      A little PU bush story

      They do. The pale yellow translucent ones from Japan were .... I dunno. Useless? Whiteline and SuperPro are probably fairly similar. There's bound to be a range of different hardnesses amongst the dozens of options on the market. The simple fact is that the pineapples don't get up inside the bush at all. They just sort of exist in the space between the washer/bracket and the subframe's bush outer tube, and...exert a bit of force between them? Or something like that. I'm sure that with enough provocation, they will simply allow one to move wrt the other.

      I'm not sure they came in different hardnesses? Going from memory only - I had set them up in the balanced setup. I also have poly bushes, so I have both poly bushes and pineapples. This is what my memory tells me at least. I'll have to take a look under there to be sure. The tramp was so bad that I managed to eject/kill a diff bushing, so those I know are stock. The tramp is bad enough that you are 200% sure you are doing severe damage to the car. It's not just chirping or vibration, it feels like you're hitting a speed hump/kerb 10 times a second. The issue has persisted between subframes! (I went from Hicas to non hicas subframe and replaced every bush a few years ago now) so I'm entirely lost. Every arm is factory.

      Need AC Compressor for R32

      By Butters · Posted

      Can recommend the Frenchys kit, been using it 2 years now with no issue, very happy with it.  Only thing for me was upgrading the thermo fan but I am super fussy on cooling.   Also interested in electric AC, partly for boot mount to have a clean bay and partly would love the idea of cooling off the car before i get in. The battery setup to do that might be tricky / expensive though.  Found this an interesting watch.

      I put Whiteline pineapples in my old 33, they came in a 6 pack of them, got rid of the axle tramp altogether, cheap, quick and easy install,  they were pretty solid units though...???high durometer???? and NVH was increased a fair bit How hard are the ones you installed?
