wanna get more power out of my vts on a low budget ?

what did you do to your nephews vts? and what time did it run?

dont get me wrong id love for you to take my engine and work some magic on it, but for the time being a refurbed head, 708's and jenveys will do me, id only get a port and polish done witha bottom end rebuild if i went down the route of wilder cams with high comp pistons etc

saxo engines are cheap to buy if things go tits up

My Nephews Vts had the following:

Standard Cams

1. Valves re-seated and knife edged at 45 degrees

2. Cylinder head skimmed to near maximum tolerance of 20 Fal (any more will cause pre-ignition commonly known as pinking)

3. Resistors in the cooling system

4. Vacuum hose plugged on the fuel regulator (Allows full pressure at all times, therefore once the injector has opened the fuel leaves the injector at maximum pressure rather than a lapse that you usually get, I won't go into this any further as many other websites will explain this more clearly).

5. Throttle switch advanced

6. Valve timing advanced using standard pulleys (valves opening just before TDC), used special tooling at work to make sure the valves didn't hit the piston.

7. To compensate the increase of Fuel, most of you will be familiar with a Cold air feed induction.

8. Exhaust manifold ports matched to cylinder head exhaust ports, you will find that most exhaust manifolds will overlap very slightly with the cylinder head exhaust ports therefore causing an obstruction to exiting gases.

9. This minor modification can add a few 1000ths of a seconds, is knife cutting the butterfly in the throttle body (get gases flowing through as smoothly as possible)

10. Silencer and Catalytic converter removed, standard backbox, standard manifold.

11. Balanced drive-shafts.

12. Quick shift

13. Wheels balanced (aim to reduce power loss)

14. ECU Ignition timing altered

15. Valve guides smoothed

There are probably other modifications I have forgotten, but the basis of my set-up was to bring everything working together; it is very difficult and takes a lot of patience and testing.

I know he was running in the 14's.

So basically it's a standard vts, congratulations on wasting your time.

I think your right mate, there are other ways of improving power that just aint been looked on, just stripping the car out makes a big difference!

I cant see how everything can be standard, guy has tuned what hes got. better than what you done mate, stop dissin

[Gandi699]

Cooling system resistors?

[stevo1600]

The above is a waste of money and time unless you have a high spec n/a vts/106 etc which would mean you would like to squeeze everything you could out of it. much like sandys race engines.

if you have the knowledge and time to modify the head etc then yes i agree do it as its free. most who want power from there vts don't have that kind of knowledge and want more power than what the above will offer. i.e cams and a good full exhaust system + enclosed induction kit and a remap slapped on top. it doesn't cost the earth and makes very good power which has been proven

i dare say a standard vts with a decent 4-1 full system will be the same if not quicker than the above spec of your nephews vts. i like new ideas and new ways to make engines produce more power. but the above just doesn't do it for me or many of the members reading this thread.

im not at all slating you or arguing with you - im just pointing out the fact that the mods you have posted will probably have more of an effect on a high spec n/a car and more of a power gain will be shown.

What have i done thats not as good then..?

Id of taken out the back seats ten minutes before leaving the house and still acheived a better time at the 1/4 than the guy.

I agree. weight saving will be the best acceleration gain on any car.

[MiniGibbo]

And even if its still a daily road car you can leave the seats in and just fit a full exhaust and a set of cams in a saturday morning and have more power.. much much more power.

[stevo1600]

exactly. a second hand set of ph3s can be grabbed for a few hundred quid...

like i say, the mods he has done would be worth it on a very high spec highcomp or boosted engine. pretty pointless on a standard lump bar the quick shift.

Buy another J4 engine, put it in the back. DOUBLE POWA.

Did not think of that!

put it dis way, i'd have him tune my car over u any day mate.

I agree with some of what you said but not all.

firstly I wouldnt go underestimating what hes done, there are other ways of getting more power out of the vts

Don't matter if you agree with it or not mate, just because you don't agree with it don't mean its bad, I personally think its a step forward. red

Ive seen a similiar setup on my mates saxo who raced in saxmax, I can tell you that would hav pissed any cammed vtr! blue

this guy makes sense that factory only tune for durability and not performance, they dont want engines to last 20000 miles think about it! im not dissing anyone on this forum but there are people out there who are in the trade that know alot more than us specialy myself and rarely come to saxp.

Id like to hear the comments from some of the other engine builders and tuners who use this website. They been very quiet on this thread...probably have better things to do though!
