Standard vs Modded

[Dub_Dude_16v]

My best mate (Blandy on here), has just bought a mk 2 16v on a G plate. Lovely mint car, looks well looked after. It's completely standard no engine mods, standard exhaust, etc.

Now my 16v is on an F plate, gas flowed head, 4 into 1 stainless manifold and complete stainless exhaust system, port & polished, k&n filter, drilled box. He has 15 inch BBS RM's i have 15 inch MiM's.

When it came down to us on a dual carriage way giving it large ( ), A) he could keep up with me and B) his car was a little bit faster  How could this be i wondered? Why spend loads of money on the engine when it seems to have made it slower?

You guys and girls got any ideas because i\m sitting here scratching my head looking empty

maybe urs needs a tune?

somethings not right with yours if thats the case. Get it looked at.

To be fair you haven't actually done anything that will increase power massively, you have got an engine that will get rid of the gases smoother and breath better, but nothing to actually boost performance massively. Valvers are not slow at the best of times, and his could have been well looked after before hand.

If you are really worried about it, then book it in to a RR and get all the fueling/air ratios worked on and see what you can get out of it.

Ah i see. Is it possible to get a valver chipped? What could i do to give it more horses? Like changing the cam and that i guess?

Think it does need a tune up because it struggles to start sometimes, runs lumpy when first started up and i polished the tailpipe last weekend and it is blacker than a coal miners face! Pumps out smoke too apparently

Nope valvers cannot be chipped, as they have nothing to put a chip onto.

Cams, bored out etc are the way for power increases.

if you can get your hands on a 'star chip' module this will increase standard bhp by about 5-7bhp.... rare as rocking horse shat.. were only out for a few years... but believe.. they work.. i had one on my old 16v.. which was standard.. but i put money on you not being able to be able to find one... they were a very early piggy back style add on, that altered the ignition curve slighty...very similar to that of early rs turbo's etc, they reffer to it as an ecu but on mechanical fuel injections (golf 16v/rs turbo's etc etc) it just sets the ignition curve... which can be adjusted by above means... (or chipping on rs turbos etc)

finding a star chip would be fun....

so i guess its a bit like finding the a-team... you find one... and it can help

What youve got is things to give you a little more BHP, that really doesnt get you up the road any faster than a standard well looked after tight engine.. what you need is torque ... higher compression, big valves, lightened and balanced flywheel, and  probably a slightly more restrictive exhaust system!.. you'll weed him every time

Lightened and balanced fly will actually loose you torque rather than gain it.

there was a k star on ebay a couple of weeks ago went for about 50 quid so they are about!
