Does the car get more repsonsive when you go with a higher displacement? for example is a 2.7l NItto fully built by you less responsive than an RB30 fully built buy you with the same turbo

[RIPSNZ]

@IceCold720 absolutly, we have done back to back comparioons between a 2.6 with everything else identicle to a 3.0 and the response and torque difference is MASSIVE. Not 1 single person who has ever had one of my 30s says they would ever go back to a 26,27 or 28, you get the best of all worlds with a 30, better response, alot more more torque, more power and rpm is not a problem if you need to rev high.

[JoelnJulie]

Fit a larger turbo and it will make the same power on less boost but response/spool will suffer.

Its all a compromise.

+ its running pump gas and its not a US dyno. :P

[ofnir123]

damn my ears just came. That's really one sweet sound there. and that power curve... looks like it's pretty responsive too

[IceCold720]

@RIPSNZ Sounds awsome! But arent 30 builds alot more expensive? When you compare a RB26 to a 2JZGTE we say both run single turbo. Will the 2JZGTE feel more responsive beacuse it has more displacement?

[RIPSNZ]

@teddysevo8you I don't know, we having done any testing with any of those turbo's sorry.

[teddysevo8you]

@RIPSNZ How do you think this car would run presently with a PTE6765?

[Kuriousgorge87]

@RIPSNZ extremely responsive 750? sounds like a more powerful version of the mines r34 lol

@MrRotormaster1 and if an air charge is cooler at the same psi, it will be more dense and therefore carry more oxygen. I still maintain a bigger turbo will produce less heat making the same boost as a smaller turbo (although it wont make the same boost as low in the rpm range). So will make more power at the same boost

[spinnanz]

@MrRotormaster1 Id have to disagree with a few of your points, firstly that a turbo runs on heat. To me this is not correct, they run on exhaust gas flow, not the heat from the exhaust gas flow. Secondly that a smaller turbo is more efficient. If this were the case, why not have one small turbo on each cylinder? A turbo of any size has its max efficiency when its flowing a particular volume. So one turbo can be more efficent than another, but only in its window of efficiency

[MrRotormaster1]

@spinnanzFor example, due to the fact that turbochargers run on heat, the smaller turbo with less heat dispersion will become hotter under the same conditions than will a larger turbo with more heat dispersion (more volume for heat to spread through). This mean that the smaller turbo is inherently able to make better use of heat that would normally be waisted through the exhaust and heat dispersion on a larger turbo. The smaller turbo, is thus inherently more efficient.

[MrRotormaster1]

@spinnanz The "air charge" would not be more dense at it is the exact same PSI, i.e. same density. I think what you mean is that the air would be denser with oxygen. I did not take this into account because with so many factors and variables left unaccounted for and not considered into the equation, real life results seldom replicate what is predicted through theory.
