what designates a T5

[silverback02]

Hi All,
I'm relitivly new to Volvos in such a way that I am trying to find out, WHAT DENOTES A T5 ?
ie:

I've got a 2004 C70 2.4 T (low press) 200BHP GT. (5 cyl)
My 1999 S80 2.4 N/A (170 BHP) also 5 cyl
Other 2000 S80 2.9 N/A 210 BHP (6 cyl)

Engine Nos are

2.4 (170bhp) B5244S
2.4T (200bhp) B5244T7
2.9 (210bhp) B6294S

The C70 Coupe did the following engines between 1998-2002:
98-
B5204T2
B5204T3
B5234T3
B5254T

99- same +
B5204T4
B5254S Denso
B5254T

2000- Same +
B5244S
B5244T

C70 Convertable
2003 - 2005
B5234T9
B5244T7

BUT THIS WHERE I COME UNSTUCK.

Up until 2004 the only engine I could find designated with a T5 was a
B5204T5
Found in 850s and V70s.

THEN IN 2005
The V70 came with, (not only)
B5204T5
but a,
B5244T5.

SO I do not know what denotes the T5 stature. all I can assume it must be the 240 BHP.

I know that the 2.3 T (High press) 5 cyl, is 240BHP

BUT THEN !!!

Vadis Claims that the B5234T Has a max output of 225bhp and Torque of 300nm, and is Therefore ,
THE HIGHEST PERFORMANCE ENGINE EVER PRODUCED BY VOLVO....

AAARRRGGGGGHHHHH

Somebody please explain.......what denotes a T5.....and how ??

Joe.
