^ yup i have read the same thing too..

I wouldnt be concerned about cam gears esp with all your other supporting mods.

Which tomie cams did you buy. As in what lift?

Awesome, good to hear.

Bought the Poncams - 256 I believe.

Cheers

So you're making 270rwkw with stock injectors and stock FPR? Surely that's impossible.

What turbo is it?

What MPH did you get at the drags if you've been?

Yes 269rwkw stock FPR and stock injectors - confirmed on two dynos. If you have another place you are 100% on dyno accuracy I would be more than happy to get a print out from there.

Turbo is custom Garrett, unsure of specs, I forgot what they told me went into it.

Car has not gone to the drags yet.

Thanks

If your making the same power on a rolling road dyno as that of a hub dyno then the rolling road dyno is most definitely reading high.

Its well known hub dyno's read higher than the usual rolling road dyno; if its not then somethings up with that rolling road dyno. :dry:

The local hub dyno here has said 30-40rwkw higher from a hub dyno is the norm. I'll soon to be running up on it so I can crack that 300rwkw lmao.

Interesting, there was only 10rwkw difference between the two (roller dyno read slightly less - but then we did a few more tunes, advanced more timing and now it makes a bit more than the roller dyno did).

I doubt taking 30-40rwkw off the hub dyno will give me a roller dyno reading (that means it would only be 240rwkw). I thought it only made a significant difference when the power became substantial and the roller starts to slip a lot.

Maybe I will check it on a third dyno - another roller dyno.

hahahah... Sorted those 'boost leaks' yet Darren? :whoops:

not yet.

ive been looking but unable to find anything sus.

my next plan was to poke a air compressor nozzle into a vacum line on the manifold and crank 30 psi into it with my hand over the afm. see what happens.

under vacum it doesnt leak, so im guessing its a silicon joiner that only opens up under boost.

Trooper, are you in WA running a wolf :whoops:

I'm sorry to say, but I find 270 rwkw a little bit out there for stock injectors and stock fpr.

At 200rwkw I was hitting 90%+ injectors.

Changed to bigger and with the 250rwkw I'm about 80%

something fishy going on.......

Well whose to say what's accurate and what's not. I've had variations of 30-40kw within days, each dyno operator telling me their dyno was perfect. What boost are you running atm? Anything else you can tell us about the turbo? See if there is a little plate on it somewhere.

Garrett have had the car and took it to PAC racing, I have a VERY good friend at Garrett and he assured me that the figures given were very accurate - because they asked PAC to do some 'tests' for product development. I just assumed that a drag team would have a fairly accurate dyno. But I am not too concerned with numbers - the power delivery is awesome and it spins the 255's in 3rd, and hits full boost by 3.2k

Running about 17psi, unfortunately I cant tell you specs on the turbo - Garrett were going to market it but the parts alone cost more than what they would need to price the units at to make it viable.

I know its full BB, similar to GT3071R and has surge slots and custom dump pipe to stop it from surging. There is no 'plate' with model number because it was a custom job and the only one that was made, they tested the prototype on my car and left it there for me to enjoy.

I would like to take it to any dyno shop that someone can recommend before injectors/cams go in, just to confirm the power figure with the current mods. A lot of people have called b/s on the power figure based on stocker injectors - until they have been for a ride. I know its not a pissing comp, but I would like to know the 'real' figures - i am about 90% on the ones I have got now. But what is more important is the power delivery, very streetable which is what I asked for, not peak power.

Abo Bob - where abouts in Sydney are you? Would you be interested in a catch up if you are near eastern suburbs to have a look at my 33?

Thanks

Heath

Trooper.

That boost curves look amazing, and for it to hold cleanly to red line like that is great.

I don't suppose you have AFR numbers?

I just have trouble with the Stock FPR and injector bits.

I have no trouble with the power and the boost, just fishy with the injectors.

This turbo you speak of..... Will they be making more, because they look like a winner to me!

The plan was to make LOTS, the problem is the cost would more than the GCG highflow (it uses the stock comp housing - but everything else is replaced). Even though it is a very good unit, and the tuners were very impressed with the performance - very suited to a street car looking for decent power + response it was thought that everyone wants something for nothing, and even though it would bolt straight on with the custom dump pipe that was going to be supplied, people were already starging to say "well I can get a disco potato for $xxxx why would I spend a bit more for just a highflow unit..

It is a really big shame it will not go into production, but I am glad that I have the only one, at least I have something unique on a very un-unique car ;)

I think the cost including custom dump pipe to fit (as the housing was slightly rotated) was going to be about the $2k mark - people do not seem to see the value of buying something that is definately going to fit, and proven to perform. The workshop I use say they have so many people buy cheap turbos, cheap dump pipes and end up spending more than that due to the fitting costs - and at the end of the day have an inferior product.

I am very happy with the turbo, after the cams go in the next stage is to make the car look a bit pretty again - starting to look a little tired on the outside, just needs a really good detail, new side skirts and new rims - or fix the scratches in the ones I have now.

Thanks

See you tonight Adam (if you get my PM in time)

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
