Intake

[ratter]

we tested complete a set up and gave as accurate information as we found, we sell many styles and brands of air boxes and have no allegiance to any 1 brand or manufacturer, I'm sure similar results would be had by using a different brand but same style of set up.

The factory box does not fit on the turbo side of the engine bay so I figured it would be a pointless excercise trying something that would not work

Have you done back to back tests on the OEM compared to an enclosed pod style CAI using the std crossover? Just interested in how they do compare.

If I upgrade from my OEM with a K&N it would be to a turbo side anyway as haven't seen the value in changing what I have to a another one on the same side.

[ratter]

No we haven't.

I don't even get time to work on Bels car at the moment let alone just do some testing.

During tuning on her car, we found the the stock box with stock filter was a restriction at approx 300 rwkw, the V8 air box and snorkel with the same filter immediately went to approx 310 with the same tune

Ok that makes sense, so the factory intake with a K&N will probably do me given the limits of the FG turbo. Works for me if I want more I need to upgrade my turbo anyway and at this point turbo side CAI starts to become a good option..

Personally if you gives you .5 hp increase its still an increase, but can you always measure it? as with some mods the benefit or gain can be hidden or accentuated by various things, environmental and operational etc. All poeple like mick can do is test to the best of their ability and provide as honest results as possible. What really matters for the customer is to spend their money in a way that yeilds the best power per dollar ratio, and have a goal in mind for the vehicle, for example some people might go a full p/west of rapid piping kit etc to give them more hp/better efficiency or a faster et, but the fact of the matter is it may make no/little advantage if we are talking pure dyno figures, If your talking repeatabliity then that is a different story, as these setups might help with this issue. This is the first example that came to mind but if all it is your interested in is a dyno sheet and having a circle jerk with their mates then there are other items that will be more beneficial to gains compared to the dollar. that's part of the reason we are all here, to see what others have done or a doing and see what results. The easiest way to get what you want is find someone who has done it already, you always here blokes say the whole "I was to build it again I could have done if for half the price" that's the case still but we still need the pioneers who have more disposal income than anyone else who can afford to pay for all the Research and development of products, who would be the biggest one here... Im leaning towards Brian Lord and Nizpro here from memory. Im not saying by all means that they still have all the best products available in terms of money for hp etc, infact they probably dont, But the other options from other companies will give you the bang for buck but how is the quality? It all comes back to education.

The reason I have left the factory CAI, I didn't think the cost of another CAI on the same side is worth the small increase in power given the FG turbo limits. If and when I decide to go the next stage then I would need to upgrade my turbo and then a turbo side CAI would be a good option. At least I am now better informed having done the research.

My current goals are to have around 300rwkw with the best possible realiability, that's why I have done the intercooler, surge, overboost. No power gains just safety and realiabilty and these add to the cost obviously but for me a must.

There was a post a little while back about good flowing CAIs helping prevent detonation, I'd be interested to know more about this if someone could help explain. If a nice flowing same side air box can provide me with some added safety and peace of mind with my tune then I would consider upgrading.

basically the short version is, the better the intake etc the less effort other things have to be put under to do the required amount of work, which normally results in less heat etc which all rob power.

You can have 2 cars both making similar power, lets say 300 rwkw, one car has minimal mods, maybe injectors and a tune, another car has the same power, but has cooler and better flowing exhaust with the injectors and tune, the 2nd car will be working easier to make the power and will do it more consistantly and for longer with out things going wrong

Mick which would you do first on an Fg, 4 inch dump or turboside intake?

[ratter]

If you are talking dump with cat I would do that, exhaust side mods help the turbo more so than inlet side. when things are close to even, but we have to remember that we need to get the air in and then get it out again, a restriction on either side will hinder gains.

We did one this week that made 316 on 12 psi but had quite a few 320+ runs as well, but he had cat and big cooler, turbo side air box, injectors and actuator fitted, the car made more power than I was expecting.

so would an ideal option be turbo side box with pod, with something like a big mouth intake? I dont think ss make turbo side big mouth kits though. would the cold air coming in through the front to the race box work better than the pod only 'sucking' air??
