rev limiter?

[craigieeb]

where is the rev limiter??? is it controled via the e,c,u or is that a totaly silly question,

and secondly how do i remove it

[Toby_Unna]

just put a viper chip in my 335 ecu and the rev limit increased from 6.2 to 6.5+

so i guess it's set by the fuel mapping chip.

bugga there's me thinking i could just whip of a sensor or something

[Richy325iTouring]

mine went from 6500 to 6750 with the zone chip

[Andy335Touring]

If you have a word with Ant i think he can write you a chip with a rev limit of your choice ?

[Richy325iTouring]

might have a word with ant and see if i can get more power

[craigieeb]

i think i might do that because the notrous realy comes on form at about 5 ish, and then obviously the limiter kick's in not long after, so i would want a prity high limit

[Andy335Touring]

Can't the noz be turned on earlier ? Say 3500-4000rpm ?

[craigieeb]

well iv got it set at the mo so when im full throttle it kick's in, and with noz you cant bring it in before 3k or it will detonate the engine, but when it come's in on full throttle @ around 3.5k it kicks in, but then it seems to have a second wind around 5k and thats when i can feel it the most

[Andy335Touring]

Has it got some form of progresive controler on it ?

What sort of BHP jets are you using ?

[Andy335Touring]

What mods has the engine got besides the noz ?

[craigieeb]

iv got some controlers there but there not wired in yet (a job for tomorow)
and im running the 70 horse jets

[craigieeb]

What mods has the engine got besides the noz ?

well it's been ported out, iv got a cam in it, 6 branch and a 3"straight thru exhaust

but i want more i tell you

[Andy335Touring]

Sounds a nice set up,i'll bet it shifts well !

More,more,more ! I'm the same mate,got to keep doing some thing to it.

Today swapped my dif from a 3.25LSD to a 3.64LSD,pulls a lot better now

[craigieeb]

iv just actually been offerd a 3.64 slipper, does it make a lot of diffrence?
im still running a standard diff

[Andy335Touring]

Definatley a worth while thing to have,will help you no end putting the power down when the noz kicks in i'd have thought ?

[craigieeb]

i'll see what my finances are like after the weekend then eh

and i was thinking about, poss a sport gearbox as well what do you recon?

[Andy335Touring]

I was going to post you a link to a cool gearing calculator so you could have a play with it to work out what sort of ratios would be best for you but the link doesn't work !

Heres some of the figures i worked out for mine with it.It's copied from an email i sent.

[craigieeb]

hey thats great andy nice one fella

[Toby_Unna]

that diff a bit better then andy

is it quieter than the last one?

[Andy335Touring]

is it quieter than the last one?

Yes and yes !

With thanks to ScottMc,top bloke !

[Paul325i]

I wouldn't put a 3.64 diff in a car that you have setup for all top end power, you'll be constantly dropping out of the power band, you'll be better off with a 3.91.

Don't run NOS for to long without the controller either, to I've seen the mess it can make of an engine (holes in pistons, melted valves)

And not alot of point making the rev limiter any higher that 6750 as the M20 won't be putting out any real power then, plus if you go up past 7krpm there is a good chance you'll spin it to bits if worked hard.

[Toby_Unna]

andy's 3.5 has plenty power right through and was bloody quick with a 3.25 diff, i don't think it's going to struggle to pull a 3.64

mine on the other hand has the same box but a 3.91 and feels undergeared, it will get to the limiter pretty quickly in top.
don't know about craigs though!

[Paul325i]

Yeah sorry i was talking about craigs car mate, not the 3.5!! lol
