I guess it was RS themselves that told him about that when he called RS and asked if CG new ICīs work with Stage IIII.

 

Toby, you stated on rennteam that RS Tuning used bigger or smaller VTG based on the C/R of your engine for the 660 special, how can M-M know which ones he got?

 

for sure the IC would make more power as we just install them on my car even with the stock ecuīs see

I think the biggest different for air volume is the inlet tubes

 

Protomotive doing 5'' intercoolers now

 

Its not now, i had the option when i got mine (4,5") almost a year ago. I think you don't need those on VTG kits.

 

I replaced mine with some 9FF C/F ones for 2000 Euro.

I don't think they give any noticeable power gains, they are more for helping airflow. Kind of useless

 

They are probably useless for you if your ECU is not updated and with stock VTG`s. You canīt just replace some partīs and expect power gain without right ECU tuning and VTGīs to handle more air. RS, RUF and like you wrote 9ff use it for a reason

 

He will have got whichever they used for the CG kit....

This is the difference when you buy RS installed kit and pay them for engine dyno time, they test power outputs with different configurations (mainly turbos on 7GT2) to get best (safe) power - What always "interests" me is that they like to test every engine like this as the results between engines and new components does differ. This contrasts with "bolt on" industry where every component is worth Xhp, it doesn't always work like this when a proper measurement set up is used, but there are very few proper measurement setups in the world so bolt ons rule

 

Yes that is probably right, like I said even top race teams/engine builders like to BS when it suits them - G can do it with the best of them if it suits !
RS are not using the CTR coolers because I couldn't be bothered setting up supply the way they wanted ie factory visits etc, too meticulous and time consuming - this is not my business. just a hobby

 

Your dyno sheet shows the same sort of mid range as mine did on Manthey's Maha set up, mine had 736NM @ 3000rpm....
When the exact same set up was tested on the engine dyno it only measured 690NM....
On the road in certain gears there is some more additional torque at this range but when held under load for proper torque measurment it disappears - what is happening I believe is the ECU adjusts for the extra flow when held under load, on the road it allows the extra flow briefly before regaining control and hitting the stock mass targetsn higher up the revs range (hence stock power higher up)

This does not show us anything about your intercoolers (yet) - forget the dyno for the intercoolers, you need to log the IATs on the Autobahn WOT up to 320kph if possible this will be the best test..... not in that weather though

 

When I called RS and talked to RS Gerhard he asked if I wanted to pay for 2 extra hours dyno time (2500€) or not, never explained the difference. I guess now he didnīt need to config the VTGīs for some reason and had bolt on too

+-10HP makes no difference to me, it will always be someone faster

 

They will have a standard size which comes configured with the kit but if you go on the dyno it gives them the opportunity to test other sizes. Whether or not anyone could actually tell the difference between bolt on and custom tuned is moot - probably not, but for some nerds it gives an added pleasure

 

My car is 700bhp, when your is ready post some times to compare, I believe that your overpriced equipment on a GT2 at the end of the day will be slower than a modded turbo convertible

 

I am glad you are happy with your 700bhp kit for less money, I am not comparing our tuning kitīs, we were just discussing the effect air tubes regardless if my tuning is overpriced or not I can afford to buy/build anything I want if this would be a contest

You can compare your car with TB`s RS 660HP GT2, I doubt your advantage of 40HP will matter there, he is on rennlist forum (TB993TT).

I think his car is faster or at least not slower than this kit for 997 Turbo:
