ohh now youve done it :lol: i was wondering when someone was gonna say that!!

love it, NM is cool, HP is for poofs :lol:


well there is a land rover that has 2450 nm torque, best they could measure, keeps over loading the dyno :) had to do dyno runs in 4th

People quite often mistake torque they see on a dyno sheet as engine torque, it's quite easy to set up your gear ratios so your wheel torque is astronomical :)

My ex-bosses drag car forced his dyno guy to upgrade to a dynapak rated at 3000nm.

Since KiwiBacon likes numbers, what boost would a 2.8L petrol have to make in order to make over 1000 flywheel nm?

awe hell, where does that leave me with a twin motor winch and a turboed V8! I'll be lucky to even find it!!!!!!!! :shock:

I've got a 2LT - does that mean it's really massive but lacks in performance and is prone to overheating and cracking?

To be honest my favorite thing was with the desiel and side pipe. Pull up by a boyracer in their cool car with the windows down. Wait for the lights then plant is with foot on brake. 2000rpm 14psi and a huge plume of deseil exhuast smoke inside said rice rocket. :mrgreen:

Nope, my little 3rz will run allover your fee ate :lol: , wont even notice your there with 2 reduction boxes in double low......
Hmmmm wonder if I hop on the dyno, I might get 4000nm at 53kw! :lol: :lol: :lol: :lol: :lol: :mrgreen:

lol youll have to catch me first .. + i have a 120 liter fuel tank .. so im guessing yourll run out of gas first .. and then you will be all mine :D

i actually had a proper laugh at that :d
+ its well known that if you come into the waikato you have to do a b-out :D
we can have a comp .. ill find some spare wheels ..... btw if my leaves snap and my axel hits you ... its a instant win for me :D

How much better would your burnout be if you fumed? That is the question I think everyone wants to see answered

Oh wait, it'll detonate and explode first, forgot about that :roll:

Am I the only one who thought this thread was quite interesting before the bullshit brigade got here and added two pages of drivel in less than two hours?

This is a tech forum, not a pissing contest.

cylander presure is the reason for det in a petrol engine as well
and timing will not always fix it

run to lean ... you get det and burnt valves
run to rich .. you get bore wash
run to much timing you get det and burnt valves
run to little timing you get massive egt's
run to much compresson .. you get det
run to little compression.. it wont go
then we go onto cam phasing air intake temps the quality of your swirl and tumble boundry layer effects pulse tuning of the intake and the exhaust, valve material

there are so many reasons you get det its not funny in a petrol engine .. seriously
if all you have to do with a d is thrown in fuel and boost untill it goes bang then you have it easy
petrols and more specifically 2 strokes make d's look like kids playfrom a tuning aspect
so please ... dont make it sound like a petrol is eazy ... when its far from it


The point was, you can't use timing on a diesel to avoid detonation. If you've got it, then a few degrees of advance or retard won't stop it.
Basically you've gotta pull any fuel that can detonate, right back to where it won't.

Hummm,You kids have had an interesting night...So ,,when exactly is my HiLux about to blow up ? It's been liveing on LPG happily for 5yrs or more.. Only one misshap with a couple cracked pistons ( Dont start Mr Bacon :) ) due to a switch/brain fade and dose of LPG on a stone cold engine.

Funny how few people understand what gearing does. It's also amazing how few dynos are calibrated properly. Which leads to people thinking they've tripled the engines torque by doing sfa.

How much boost depends on what torque your 2.8 is already putting out and how good your fuel and intercooling is.
If you could get 280Nm from your 2.8, then you need to increase the air density by 1000/280 = 3.57 times.

To get 3.57 times the air density with a 60% efficient turbo and 60% effective intercooler you need about 58psi boost. But at that your intake temps will be about 130C, I don't know what fuels won't pre-ignite with those temps.

So you chase your tail around in circles with engine mods to handle the torque and reduce the compression ratio until you've got it working. Those probably reduced the engines efficiency enough that you now need more boost or a way better intercooler. The better your intercooler is the less boost you need (within reason).
70% effective intercooler would only need 52psi and your intake temps would be down around 100C.
