What gains?

[Plattsy]

What gains am i looking at with a supersprint manifold for a valver, decat pipe, ktec cat back system, and a viper IK, what gains am i looking at over standard valver hybrid power, (williams2 engine)

Ten brake, or a few tenths off your quarter mile, I'd guess...

nar - if you need a real good manifold back system to get the best out of a manifold change - i recon 3bhp - 5bhp gain.

Mine has a Magnex cat back system, magnex de-cat, piper induction kit and that got 144bhp last time.

whats that on a valver though?
Ive got the parts i just need to get them fitted jus wondering what gains id see over standard, ktec have a proven 7bhp from the manifold, then theres the decat, rest of the exhaust system and a viper IK which last time i checked claimed 10bhp(bollocks) increase.
Id be happy with it though, aparently standard the car was running 162bhp without any modifications

and who told u a standard williams engine is putting out 162bhp?? no chance, doubt u would see that power with the mods youve mentioned either. forget the 7bhp from the manifold too been talked about many a time on here already.

The rolling road printout told me 162bhp and 135bhp at the wheels when i got the car. I dont care tbh its going to be better than with standard items anyway. i might take it up on the rollers and have a look.
Next will be cams and pullies and headwork me thinks!

Don't forget, amny high milage, standard cars will be running down on std power.

My RSi, whihc has had a very hard life, and is on 125k is runnign std power, according to 2 seperate rolling road read outs, thats with a relocated filer, de-cat and straight through system

well standard they are 137bhp so that is a 7 bhp increase for all that.

and my clio is still under 100k JUST lol

ill have to get it on some rollers somewhere then see what it reads at. at the end of the day i know it will be better than standard airbox, manifold and removing the cat! But by how much is to be seen
