turbo rebuld

[T5frankie]

i still need to know what downpipe to buy

[p fandango]

denser (is that a word?)

yep, correct spelling as well

[smithy]

i want 380-400bhp mate

not with a 19t you wont but as i said before 350 bhp tuned properly will be a fast car and i know that james car will be fast with the turbo off my car dont worry about that mate

[p fandango]

i still need to know what downpipe to buy

depends what turbo you get

also my turbo fits the standard downpipe too bonus

never said i wanted a 19t, is that the only turbo that i will need an angled downpipe for?

[T5frankie]

decat pipe and straight through exhaust as well

all the volvo later turbos need an angled down pipe mate .i ran a race cat on my v70 with a 3in system up to the turbo then it was reduced to 2 3/4 to turbo

Well I have worked it out & you need to be making about 360 Ft Lbs at around the 5700 mark to make 390 bhp.

well its making 335lb ft at 4000rpm and 262bhp then goes down rather than climb hence i need a bigger turbo

it dont thing the power figuires work like that mate it all depends on the setup

if the power is dropping of eairly have you looked at the timing

[T5frankie]

if the power is dropping of eairly have you looked at the timing

but the car is running sweet, smooth no lumpiness etc

[T5frankie]

if anyone else has a dyno graph where did you get peak horsepower in the rev range?

[smithy]

6k mate then hit the rev limiter

[T5frankie]

6k mate then hit the rev limiter

anybody with a t5 who was at hlm? just checked my graph it made peak bhp at 4000rpm then went flat all the way to 6000 rpm the torque peaked at 4000 at 455nm then fell to 270nm at 6000 rpm

You can make it sooner in the rev range but the torque will have to be sky high.

[T5frankie]

wobbly made his peak bhp figure around 5600rpm

[Santa]

hhhmmm cant quote you Dave.

Your working assumes his Rev limit is 5700 though doesnt it?

If BHP = Torque x RPM / 5252 then

Torque = BHP x 5252 / RPM

[Wobbly Dave]

No I am not assuming any rev limit - I am just working from the most common peak power point for the turbos used in Volvo.
