Title: getting an 8v to rev faster
Post by: sharki786 on 01 August 2011, 13:02
as above realy. as some may be aware that i have stuck in a lightweight & balanced flywheel. now my mate drove it (he drives a cupra R REMAPPED) and says mine dont rev fast enought. i know its an 8v but i wanted to know what else i can stick on it to make it rev that bit better? car atm has a cat and a straight pipe to the backbox. no other mods performance wise.

many options are welcome but not p1sstaking 1's :grin:

when you say rev fast enough, do you mean when stationary?

off the mark. it starts going after certain revs (2.5RPM)

Still don't get if you mean when driving from a stand still or just parked up and revving?

So it dont rev until it gets to 2500rpm?
Hmmmmm
How high does it rev to?

sorry i think i have confused everyone. it reves all they way into the redline.
my mate drove my car after we spoke about few things that we have done to our cars. after he drove it he said it was sluggish and only starts reving faster once it gets past certain revs (about 2500RPM)

Put up with it! Unless you spend loads of money you wont get a lot out of an 8v

He has same engine in his LCR as what i have in my golf

its night and day difference between his engine and how it revs and yours

Title: Re: getting an 8v to rev faster

Absolutely no point! The peak power is way below the redline anyway.

For instance my 16v revs to 7000 but the peak power is aroun 6000.
Revs do not make power.

Post by: SoundillusioN on 01 August 2011, 13:28
To make it rev faster when on the move or in English, accelerate faster you need more power, simples.

thats what my cousine said, his comparing his cupra to my 8v, and my cousine has a 16v mk3 and says since i have had the flywheel fitted it has made a BIG diffrence.

& as soundillusion says need more power, which is of course true.

lighter internals increase rate of rpm change I believe, but easier and cheaper to buy a new car I suspect.

Things like having a 16v engine with 16 smaller springs rather than 8 big springs, lighter crank/cam, etc.  Modern moves to electric power steering, load-sensative alternators etc, all reduce load on the engine and help.

Well there's probably nothing wrong with your car and someone who has a much quicker car is just stating facts rather than pointing out a problem....  Sadly it is what it is, you could spend lots of money and get a few more horses out of it but for that money you could get a cheap transplant, probably.

you could do a 20VT swap fro a decent price if you choose the 150bhp lump out of something like a mk4 GTI, With a remap you would be looking at around 190 hp

or even cheaper u could wack a VR lump under your hood..

To get it to rev faster, you could lighten the flywheel and Crank pulley.

This made a noticeable difference on my 16v, cost to effect it is probably the best thing you could do, it isnt expensive and you will notice it pick up much quicker

I must get round to sticking one in my 16v, these engines are crying out for a bit of extra spinning freedom.

£69 including return delivery. He said I should have it back by the end of the week provided it arrives in good time. (tracking progress still says processing though  :angry:) Cost me nearly £15 to send it through royal mail!

Whats the standard weight on a 8v flywheel? I thought the were lightened and the 16v were heavier ...i was led to believe.

Thanks

4 branch manifold, ported head, ported throttle body

to make it rev faster it needs to be able to take air in at a greater rate with least resistance and to do the same getting it out

= ££

Around 10kg I think. Looking at previous threads, the flywheels are lightened to around 6kg.

Its only expensive if you dont do it yourself, porting can be done fairly easily.
4 branch is a bit more difficult, but something to save up for after you have done all the free/cheap bits.
I would like to add, most modifying costs are relative to how handy you are.
On N/A engines you can achive a fair bit on a low budget if you have the time and dedication in doing so. in that lies the reason it is easier to stick a turbo lump in, more power at more cost but less time in the garage :smiley:

Breathing helps the car rev more responsive.

My mate just fitted some carbs to his mk1. It barks at you lol rev needle goes straight up, and straght back down.

It's now for sale on edition  :wink:

I actually had those two written down next to 'lighten flywheel' on my 'to do' list. In my excitement of being paid I just ran off to the closest post office to send it though.  :rolleyes:

Update; ooh ooh! Just had a PM from Mart (hotgolf). Flywheel arrived at his today, already done and booked to be collected in the morning. Should have it Thursday or Friday! Muchly excited now!!!  :smiley:

To be fair after running up boneybradleys 1.8T followed by my 8v on The Doc's dyno a few weeks ago it was pretty impressive how much quicker the 1.8T revs in comparison to the 8v, it's just a sluggish engine :grin:

Granted, but if someone came to you and asked you how it was done you would help them on the right way.
Time and manners can get you a long way, most petrol heads will help you out just for the return of the favour or a few cups of tea :smiley:
