2JZ Cressida

[Dell'Orto]

Think it was on TM for $16k?

[BlakeNZ]

Sean wanted 14k for it last time i saw. 350 hud kw on a dyno that reads 10 percent higher than a dyno dynamics/torque performance rolling road dyno.
i can't work out how it made 350 on stock injectors, when the same tuner says my ex soarer ran out of fuel at 325 kw with 540cc injectors and 044 pump. still confused.
Yems, have you got good facilities? eg hoist/workshop etc?

350 kw i thorght it was more been ages since i seen him or the car

Maybe the dyno correction factors being used on each day were different somehow?

Your dyno result sounds closer to reality based on what you said in your post about fuel running out. 370kw on 440's is stretching it juuust a bit.

Totally, anything over 300kw is pushing it on 440s. Even 550s would have to be pushed pretty hard to hit 370kw, I'd have thought.

BlakeNZs sounds almost on the light side for 540s, though that car may have been running an auto which may skew the reading a bit - I forget?

[Mr Ree]

I think my duty cycle with 550's was around 80-85% from memory when I dyno'd my car last year and that was 310kw on a rolling road.

So going by that, I honestly cant see 370kw from 440's, even if an FPR was being employed to try and up the flow. Its just too far from every other result I have read in the past.

Yeh dude, pretty much anything i need. Have built/played with a number of cars. Burnouts are my specialty haha. Have an 8 bay workshop at my disposal with a range of hoists. most of the metal fab tools in house. have just bought up $6k worth of snap on tools from our local snap franchise holder who went out of business (so the cash price was a fraction of that). My good mate owns M&M automotive who build/fabricate all sorts of race cars. My Tig welder lives there. Another friend of mine, Brent, owns Dynopower which is also just down the road, has a 4wd rolling road.

Have just been tossing around the idea of another cressida.. only because the rolling bodies are cheap. an FD rx7 would be cool with a 2jz thats for sure! oh the possibilities.

oh and i had 800cc injectors, with an 045 bosch pump, and at 430kw they were 85% duty cycle.

[strx7]

hub dynos tend to read a good 10-15% or more above what a rolling road type dyno will

[Lith]

That depends on lot of things, most rolling roads in NZ aren't much our any harsher than hub dynos. That side, I had hub dynos in mind with my comments... 370kw at hubs ain't happening with 440s

[2jayzgte]

The good old rolling road vs hub dyno discussion...

Can't stand them personally I really think this RWKW or HP BS is straight US propoganda and the rest of the world is just taken a huge bite.

I also notice over the years how the Japanese very really state RWHP numbers its mostly the US NZ and AUS,personally I don't get it I tried to follow it but being involved in the Supra scene for over a decade and listening to some of these stories makes me laugh and then to make it worse getting out on the track with some of these guys who run all this RWHP man I gotta say some of these figures that people present are straight up a HOAX in the real world.

The amount of times I've ran at Manfield with a car with this much HP on the front cover of NZPC hype this hype that hahahahahha in a near stock HPowered car like mine and blown them into the weeds...Some of these figures quoted they must be a HOAX.

[sergei]

There is also a misconception about more power = faster.
Even if they dyno reading are true and not inflated most of the cars in NZPC are show cars and built to get max peak power. Getting max peak power is easy, but it is useless if you have a huge hole in the middle which really matters on track and road.

Say a 2.0 500Hp GT4 with massive turbo will be slower than 300Hp with smaller turbo on the track (having everything else equal).

[Mr Ree]

Exactly, its all about USABLE power.

A car with a relatively small, highly responsive turbo with half the power output will generally beat a car around a track that has been fitted with a HUGE output turbo with lots of lags.

HP means nothing without good response, traction and acceleration out of corners.

Lol this moved off topic quite quickly. Not everyone are building track cars, especially when they are Cressidas.

[Dell'Orto]

No way, Cressidas are the next AE86

Yep maybe not but at the end of the day you still want to be able to drive it safe and I'm guessing this guy with this car hasn't got the 1. the brakes to handle the power 2.the suspension set up to use the power either 3.the rubber to put the power down so whats the car good for burn-outs and Dyno runs.....Yeah Next.

[Snoozin]

Whatever happened to just doing something because you could? Not because it had to be fit for a certain purpose.

The car is clearly safe because it hasn't been written off into a tree/bank/post/truck...

yip, if you want a car to be fast from a to b you aim for maximum area under the curve.

prob cos its got no driveshafts

Pretty much all my car was good for good old fashioned power skids.. fun but only good for occasional drives. Hence why i own an 03 wrx now which is only 300hp and 100x the car my cressida ever was.
