How Do I Make It Sound Like This?

^^That thing sounds crazy!!

[JamesLumley 4]

Rally cars are generally all induction noise as there are strict noise limits on the exhaust.

 

We generally have to stay between 98-100db for a static noise test.

 

My exhaust is 98db but you can't really hear it over the throttle boddies....

Well its currently got twin 45's on it, so hopefully the group n back box will compliment it to give me the sound i want!

Sounds best half way through i think

[Sandy 189]

Cams and rod-stroke ratio have alot to do with the note, combined with inlet acoustics of course. John Read's XE engines always sound different at rallies, you can definitely pick them out! Colin used one of John's cam profiles in this 2.0 16v XU, which gave it a very distinctive induction note, different to John's XEs, but quite different to other XUs too:

Note also the utter lack of understeer compared to other 205 videos, Colin's chassis in action!

Induction noise is incredible! Sounds like ITB's

[24seven 104]

changing the inlet manifold on my XU7 from the standard plaastic thing to the GTi-6 cast alloy lump has completely changed the induction sound of my car. it's a lot less burbly and a lot smoother. before there was a loud spot around 2.5k - 3k and after 4.5k it had the usual XU rumble to it. now it's smoother throughout and a bit quieter as well. Need to get some proper cams on it pronto!

Sandy, is that Vauxhall XEs you are talking about? Is John Read's car, in those videos, using a Vauxhall XE engine?

 

I like this vid...

hill climb

 

EDIT: just realised it's Ian Beacham and not John Read in those videos. DOH!

"Colin used one of John's cam profiles in this 2.0 16v XU, which gave it a very distinctive induction note, different to John's XEs, but quite different to other XUs too"

 

It's a 2.0 16v XU that Colin Satchell built for Ian Beacham, using John Read cams.

 

Ian Beacham's car (he's driving), John's Cam profiles, Colin built it.

 

That video you posted is Castle near Lostwithiel, you just can't see how steep that hill is, strictly a second gear slog in most road cars.

well i fired the 205 up today for the first time and oh my god does it sound great, ive never heard anythin like it, it sounds so powerful i think is the only word for it, thought my fillings were gonna fall out but its not excessivly loud its just has a very hard rumble note to it, once ive fixed the leaky carb mani and start it tomorrow ill try and record it

I saw and heard this car go at Llandow today, and it sounds so unlike any Mi16 ive head before, especially the note from the exhaust, and the induction roar when pulling hard down the main straights

Sounds very much the same as mine! I notice from the other video that you have the plastic inlet resonator box removed on the inlet manifold, its suprising how much difference it makes to the induction note isnt it?

What does it do in performance terms Dan (removing this box)?

[taylorspug 7]

Probably next to bugger all. But i figured its only on the std car to make the induction noise less intrusive, not something that was going to bother me-more noise=more fun . The box isnt on the BTCC inlet either, and neither are the trumpets on the end of the runners inside the plenum...

from where i was stood at the bus stop, to hear it accelerating away i was guessing it was some mentally tuned TU. When i walked past later in the day (pretty sure it wasthe same car) it looked like a gti6 on bodies???? Could tell it was cam'd up due to its complete refusing to idle. Didnt like the exhaust system, but it didnt half shift some on track

[Sandy 189]

Ah I'm glad they made it, it goes pretty well for "only" 235bhp doesn't it?

 

It's a diesel block overbored with 86mm crank to 2.0 with Shillaber ported XU7J4 head.

I had a good chat with him seems like a nice bloke and very helpfull we had a good play on track i thought i was going to be massivley slower than him but i think i did ok after a few laps.

 

As with me he is very impressed with you and colin.

I think that this is a very nice sounding car.
