Silenced Or Not

[gyles18]

hmmmm i was kinda expecting a bit more tbh though from what i was told.
i spoke to the guys at a-spec tuning in america for about a month before i decided on the turbo to get......although it is very strong and smooth i was kind of expecting a little more from what they told me.
tbh though, the car is sitting at home at the moment not doing much and it does feel fairly strong and reliable.
Pip told me to go back up after id done another 3000 or more miles for some more mapping as everything in the engine is brand new!
here\'s what they claim on there website anyway:

The yank dynos do show more than the uk ones. I\'ve also got an A-spec GT3574 0.84A/R and I\'m hitting some pretty good figures with it for the size of turbo it is. I\'m also running Pips big bore system and got tested at 99dbl but they said it would be quieter if I hadn\'t bounced the throttle around 4,750 rpm. I\'ve seen 441bhp/370ftlb at the flywheel on 1.05bar on the high setting but I hardly use that because the 0.85 is quick too

I have to say its a very deceiving turbo in its power delivery especially when pip maps it. He loves the smooth transition to reduce step out when driving it hard. The feeling is very different to the twin turbo setup. Plenty of good comments on the kick at cadwell from passengers in the low setting :p

Would fitting a silencer affect fueling? Im tempted to fit one, motorway driving is doin my head in feel like i\'ve been at a night club after half hour!!

Sometimes a midpipe can make it louder in the car because of the restriction in the midpipe !

Usually best to get it checked if your worried about it, a silencer usually doesn\'t boost at the same point (usually more restrictive)

what\'s your system like when your cruising? is it very loud? could you do a 5/6+ hour car drive in it and not be left with out hearing?:2Confused

i use to have a bung for my nur-spec. handy for long journeys, although still loud but quite restrictive!
