muck around with some coppers first to get the heat range and gaps right. then get your platinums.

My bad. Sorry I don't think we will see very much power out of mine. The highflow you guys have is pretty damn good for the bucks I must say.

I seen a 440 bigblock in one so why not?

EnricoPalazzo, the dyno (and the power figure it provides) are not the be all and end all of perfomance factors that effect your car. I think you can appreciate this. The power curve is also important if the gearing is not tollerant to a sharp peak. Your right about the 'lag' being no different. The same rpm is required to spool the same turbo regardless of the intercooler. What about how quickly the engine revs? This is the very thing that is 'acceleration' - translated from engine to drivetrain and the car. It effects the 0-100 and 1/4mile etc. A light flywheel won't show any gain up on the dyno. Will it improve acceleration? Yes. Will the turbo spool at a lower or higher RPM (Lag)? No. Now for intake piping volume... The volume of the total intake run from turbo to inlet valve effects the 'time' it takes for air to reach the 'combustion disco' at a particular pressure and volume rate. The stock hardware is a represents a very low total volume Vs the GTR cooler and pipe work. I think I remember sydneykid doing some very basic calculations on this. The stock turbo produces only 300HP worth of air flow max, in fact the turbo spends most of its acceleration time working up to this peak so infact the bulk of accelleration time is spent with much less than 300HP worth of air being pumped through. Another real world example is the old 13B turbo boys getting under 10sec using IDF webber drawthrough turbo's. Faster at the time than the intercooler efi boys (who were making more power too).

I bought 1 cam gear. It increases the power and allows manipulation of the torque curve. You can't see the cam gear, it's covered by a dust cover. Simons turbo is high flowed. Quote "I tried something different by hi-flowing the stock rb20det turbo. The result : Big top end flow , Minimal Lag."and "I ran 12.9 @ 112mph. Hi flow , intercooler , 1bar boost , exhaust." My std cooler has 11.5psi before it at 10psi. Not much of a problem really (thats my car). Haven't tried a test at 12psi(plenum) yet to see what sort of drop is there. When you say hybrid coolers are "..a reasonable size" what do you mean? Reasonable size ought to cover the flow rate of the intercooler as a match to the flow rate characteristics of the choice of turbo. Thats the only point I am making, well that and GTR intercoolers and others rated at 500HP are silly upgrades for a stock turbo R32. The one area no one has made argument to me on is; that I don't know the flow rate of the hybrid cooler, so how can I say that they aren't a perfect match? You see I could be wrong. I'll reserve judgement on the 'hybrid' stuff, unitl someone produces a flow rating that puts it one way or another.

oh and to shut the 'but your a great driver' and 'but you get traction' people up... My 13.3 was a 60ft of 2.3seconds. Not great traction and not idicative of a great driver, specially with a 1 second reaction time.

paul, The most common reason 'so-called' powerfull cars run slow times is because they don't accelerate fast enough. What!? you say. Not accellerating fast enough? Yes. The dyno (lovely tuning aid that it is) does not have mystic insights into a number of very important performance factors. How long in seconds (or fractions of) does it take for the 'off boost' engine to get to it's rev where turbo spool begins? More importantly, how long does it take for an overly large intercooler (say 150HP over sized) take in seconds to build full boost (and its peak power) after a gear change. These questions can't be answered by the dyno. Nor can the dyno tell you what sort of benifit a lower inertia has on a motor. However both of these things will effect the acceleration.Both of these things are basic racing 101. How much time do you think ferrari spent on the right sized intercoolers for their turbo stable, include the turbo formula 1 era. Back to the stock intercooler thing. The stock intercooler IS a peice of crap. But the thing that makes it crap is the core and tank design. The postition is great, the pipes short, and the size/volume is just about right for the stock turbo. Apply as much thought to intercooler design as turbo design and you will come out on top. 'She'll be right mate' is for people who only want to go as fast as everyone else before them. Go buy the same intercooler as your mate and don't ask why he chose that size, the odds are he doesn't know.

here's a better time frame than lagwagon suggests: If my car gets sorted on wednesday, you can come down and see a stock intercooler and turbo'd gtst keep up with the hiflow and front mount advocates. They will even have nicer and wider tyres than me. Perhaps this might settle the argument once and for all. Operative word is 'might'

raasclaat, actions speak louder than words mate. I can show you my time slips for my very stock car pulling consistant 13.5's. There are many a gtst struggling to do low 14's with the intercooler/stock turbo mentality.

good luck beating my time with this advice. No one else has. You RB20 boys needed hiflows to get these sort of times.

It's the fact that you don't have pineapples

RJB, Yeah it's like having a ride in a restricted class race car. In most of these type of classes many components are limited to factory and yet the cars go like stink.Spend some time on efficiency and it pays off every time.

don't even worry about it mate. not until the noise is louder than your stereo when you are driving down the road.

I'd like to thank my producer and the policeman who helped cover up the assasination and the fluctuating monetary market. thankyou all sooo much

To a point you get what you pay for. $500 paint job isn't going to win you any showcar events. Some paint materials can cost upwards of $6k trade. And certain paint styles and types can cost more in labour and materials to get an even finish. Multi-flip paints can cost more not only because the paint costs a bomb but also because mistakes mean more materials are used to correct errors, sometime unavoidable ones.

well the cam will be good if you match it up to an ecu remap. It's very easy to put the cam gear on, do that yourself. Then take it in to get a remap with the cam timing setup while your at it. Is the exhaust all the way from the turbo back? The flywheel/clutch mod is a good one too.

I'd like to see it too.

Exhaust , front dump pipe, ecu remap ($600 worth), Lightflywheel (if its a manual), Pineapples, exhaust cam gear etc.. Have a look at my '13.4sec how to...' in the forced induction section.

No I don't have a spare granite rock to hit my head with, at least not one the right shape to make me believe you. I believe there are already plenty of front mount advocates past and present running much slower times than me to make the point your looking for. In fact you have one of those cars

Full boost on a stock turbo produces about 300HP worth of flow at turbo(that is a stock RB25 turbo not the dinky RB20 one). GTR cooler 450 -500HP worth of flow. Bad match. your at least 150HP out of whack air flow wise. Add the extra volume of the new piping and it's not real flash. Mate save your money for a mod that will actually make your car go quicker. Front mounted intercooler is barking up the wrong tree at this stage. For the record I am not against larger intercoolers I am just 'for' getting the right sized one and not pissing money up against the wall with silly mods.

I drink the type of petrol that goes best with watching a quality movie like F&F.

the noise is most often caused by the the clutch thrust bearing. If the noise goes away or changes when you put the clutch in then thats it. Don't worry too much about it.

I like to drink petrol and watch F&F because both are great pastimes.

I don't love my stock cooler, Paul has un-natural ideas about having relations with automobiles and their parts that we don't all share. The idea is match your flows and you get go. Mismatch the flow and you go slow. (thankyou Doctor Zeus) so don't go slow with flow cost dough crap, when you can be a flow-match-go chap. The GTR cooler is about the right upgrade for a stock turbo if you like to hit your head with rocks and eat poisonous mushrooms, cause only then will you seem to get a quicker time.

I like F&F cause its very realistic and I love honda's.
