hybrid - slow?

[bendee]

ive just fitted a decat to my hybrid now for some reason it doesnt feel as fast as it once was.
it has a valver manifold, decat, scorpion back box and itg panel filter so maybe needs a chip or something, a remap maybe?
would the decat make it slower somehow?

maybe i was imagining it but just didnt feel like it has in the past.

valver manifold is no doubt causing this. they are useless on the F7R imo. my friend tried both on the same day and the valver one gave more low end torque and strangled it up the rev range

yeah ive been told a couple times the valver manifolds better low down i thought maybe with a remap or chip it would help sort it.
also its only since the decats been on its felt a little slower.

hill power swear by the valver manifold.. i tend to agree, why do the race spec cars not use a Williams manifold?

I have been told the effect to top end is minimal unless you are running 220bhp +

Torque wins races, BHP impresses your mates.

i have valver mani and mine is a ripper!

[Hulio]

The valver mani is bloody heavy though!

Sounds like the decat is losing you back pressure, put the cat back on.

why is my clio faster round the track than my brothers diesel golf which must have double the torque ;)

Depends where it is in the power band.

Bit of a sweeping previous statement, a balanced graph and well mapped engine is better imo
