22nd February 2006, 16:26

Iv got the 98bhp VTR with a pipercross viper, 4-1 piper manifold and will be getting a Magnex single box system very soon. Im considering a remap aswell any tips or rough BHP figures please.

What BHP will i be getting and what can i do 2 improve it ????

22nd February 2006, 16:32

Just to add anyone ever had thier fly wheel lightened and balenced ?? the good bits and the bad bits. please if any knows anything about them

22nd February 2006, 17:04

i`m using a flywheel from an axgt its alot lighter but i dont think it is balanced!..

22nd February 2006, 17:06

you dont need a remap for those mods, id say bhp 103+-1 or 2

Does the flywheel make any difference ???

I've got poor fuel ecomomy could any of these things ive had done effect them.

The lamba sensor which was orignally in the top of the old manifold is now in the manifold and the one which went to the bottom orignally is now just in an area where their is plenty of warm air.
Or should i have a GMC sleeve on it.

I hear different stories about difrent things.

is the engine managment light on getting the sleve will turn the light out and may make it run better

No the light aint on but it does work as it comes on jus b4 i start the engine. i using super unleaded an its making no difference hardly for the extra money. What else can it be ???

when you begin to mod your engine you will noticed fuel economy becomin less econimical, thus because you are changing standard parts to say bigger parts/ open parts which increase BHP. i have a manifold and bmc on my vtr and the air filter alone was drianin a noticeable amount of petrol.

1st March 2006, 23:47

I'm thinking of doin the same sorts of mods to my vtr, but I'm concerned about the MOT with the manifold and full system etc! Will it pass?

1st March 2006, 23:58

only if you put your genuine manifold back on mate. well saying that scott's saxo passed mot without a cat.

Drop a 16v lump in there! Or get cams, remap, decat etc.

wise words from dan. there they ways forward mate

I was looking at getting cams for my VTR MK2 and lowering it 40mm with air filter and full system fitted from a company they wanted a total of £1500 i could insurance a FTO for that amount what else is out there for less money

2nd March 2006, 05:30

cam: 400 ?
lowering 40mm including springs: 200 MAX
fullsystem 300

they must be charging "interesting" labour rates

gonna say you may aswell have a go yourself for that price! my lowering cost me £90 for the rear torsion as it was about a 4 hr job i think. i did the springs myself.
