SURREY Rolling Road pt4

[JonMad]

The Scorpion one, for another £100 extra, will go with the Scorpion decat downpipe I now have in a box in the garage. Whereas the RS Tuning one above replaces the current cat (which replaced the decat downpipe). I got confused by there being two ways to replace the OEM cat:
- OEM pipe -> OEM cat --> rest of system (what I now have)
- OEM pipe --> decat downpipe --> rest of system (what I did have)
- sports cat --> decat downpipe --> rest of system (Scorpion sports cat option)
- OEM pipe --> sports cat --> rest of system (RS Tuning sports cat option)

414 bhp from 4.2 litres here - even worse!

And 435 from 5.2 terrible!

308bhp from 4921cc.

That's clearly 4.9 litres but everywhere seems to call the V10 a 5.0 for some reason.

Yep - E39 M5 4,941cc - "5 litre", unless you use maths.

The original Dodge Viper is my favourite car in BHP/capacity terms. 50 per litre. Good old American engineering.

Possibly the same reason the C63 was always referred to as a 6.3. When it was a 6.2.

That’s some great numbers it’s putting down YK.

Fan noise warning.

What was cool was the first run up was 400 point something (bam!), then 399 (boo!), then 403 third time through (yay!).
