I dont know if anyone else has noticed this but why haven't all the type r models got the legendary Vtec status on forza 3 the hondas on that have Vtec and also have the powerband that hondas have when the Vtec kicks in and also another point when you have a turbo car you should at least hear a waste gate open or the option of a dumpvalve does anyone know of anything like a patch ect for this or am I hoping for nothing ?

Sounds in GT5 are bad. Just plain bad. VERY few cars sound good.

There was a thread not too long ago on this same subject about the Hondas.

Ohh yea forza has the sound quite similar. More gutted about dumpvalve and waste gate sounds from turbo aspirated cars.

(Edited for the inconvenience of someone wanting full stops in a sentence.)

Honda fanboys love their VTEC.
What about:
Alfa Romeo - Twin Cam
BMW - Double VANOS
Daihatsu - DVVT
Ford - Ti-VCT
GM - Alloytec
Hyundai - MPI CVVT
Lexus - VVT-iE
Mazda - S-VT
Mitsubishi - MIVEC
Nissan - VVEL
Porsche - VarioCam Plus
Subaru - AVLS
Toyota - VVTL-i

VTEC just kicked in yo! (all that noise for 5 extra hp) :-/
 
Id say they will never fix it :( the sounds for vtec are really bad no vtec cross over this is from a guy with a real B16 typeR civic and used to own a EP k20 civic
 
Drive the SRT4 Neon if you want turbo sound and BOV. The BOV on the SRT is really loud. BTW, it is loudest using the roof cam.

The Nissan GTR also has a nice BOV sound.

I am not a Honda fanboy, but I would like the hear the Vtec sound on the Hondas and the VCT sound on other cars that have it. I did have a '92 Hatch with a Integra GSR swap, and I can tell you that when the Vtec kicked on it, it was more than 5hp. However, I have driven a few B16's and the Vtec on them does not hit near as hard as the GSR motor did. Having said that, my '01 Cobra and '09 Challenger both have VCT (with the Cobra being a 4v engine), and you can definately tell when they switch over, more so with the Cobra.

Um... 2001 Cobras did not have IMRC. Nor did it have VCT.

... but I could be wrong.

It's just the way the game is, the sounds are terrible and i'm willing to argue with anyone on that.
 
The problem with the Honda VTEC sound and many other characteristic engine sounds is that it is an induction sound. PD don't do the induction-part of the engine sound that well.
If you think the VTEC sound is bad though try comparing the McLaren F1 sound on GT5 with real life. The F1 has an epic V12 soundtrack and an induction bark that would scare a Honda motor silly. On GT5 it sounds like a low compression turbo-6 :crazy: :crazy:

The wastegate is not what you hear when releasing the throttle whilst on boost, that's the dump valve or blow off valve. The wastegate is an excess boost valve on the turbine side of the turbo to prevent runaway boost.

I knew the earlier 4V 4.6s had the IMRC, but I thought they replaced it with VCT in the later years, but after looking it up, I was incorrect. However, when it hits 4,000 rpms, it does turn into a different animal, that is for sure.
 
Yes when a bov and dumpvalve are not installed. It is the waste gate you hear in a chattering sound but that's not mistaken for turbo chatter. If that was the case that the waste gate didn't do that then what happens to excess boost pressure and gas ? Surely that isn't left inside the turbo ...I only know this because alot of my friends have turbo cars and ther mechanics.

Wastegate chatter myth

There is confusion in the automotive world about so called "wastegate chatter" or "turbo flutter". A noise created on lifting off the throttle in a turbocharged car, commonly described as a chipmunk or a rattlesnake, is often stated incorrectly as being a result of the turbo's wastegate closing.
The noise is in fact the air compressed by the turbo passing back through the compressor wheel of the turbo after the airflow is abruptly halted by the throttle plate closing, called compressor surge.
A compressor stall like this can cause excess stress and wear on the turbo's shaft or bearings under higher load applications of the turbo (around 15 psi (1.0 bar) and greater depending on the trim and flow rate of the compressor side).
Actual wastegate flutter occurs instead under partial boost conditions such as partial throttle near the boost threshold. It sounds like FftFftFft not ShuShuShu and is caused by the rapid opening and closing of the wastegate at boost levels near the spring pressure. It is commonly heard more clearly and may be more prominent on cars with modified intake silencers, up-pipes, and or downpipes, and is not harmful.

Yes what I'm saying is it's not turbo chatter thats caused by a airfilter on the outlet of the turbo lol the waste gate is to get rid of excess pressure

It's roughly 60hp (peak) on the 8th gen Si, which has VTEC on intake and exhaust (not just intake only, like most of your examples), and you can certainly hear/feel when you hit the rev range. Just sayin.

And yes, the sounds in the game for the most part are pretty terrible, one of my biggest complaints of the game.
 
So you're telling me, that without VTEC, a 197hp Civic would only have 137hp?

(previous GSR owner... I was impressed with VTEC at the time, and then I was introduced to torque via an 03 Cobra.)

Yeah that sounds about right.

I can tell you that on an autocross track, the Si eats Mustangs for breakfast. Yes, even the new one (maybe he was a crappy driver?).
