16v head with 2mm oversized valves

because when I sort out my setup for running E85, I am going to have duel fuel cells - one for regular petrol (99 octane shell optimax) and the other (much smaller, maybe 5L) for 'test fuel'.

'test fuel' is going to be several different things - not just E85 - there's a whole load of interesting fuels out there which I want to examine

it would be nice to have the capacity to run 6 different maps with a dash switch to move between them

its quite possible that certain fuels will be better for different conditions

I don't know for Motec but for their price they should make even coffees ;p check about them

Interesting idea

 

cheers for the links

 

what about 'fuel' saturated with liquid oxygen......that could be interesting

a test for my garden engine

 

try to not explode anything

 

Nobody please do this - LOX is VERY dangerous and only trained scientists should be allowed to play with it in the safety of their garden sheds

(incidentally - if you soak a charcoal brickette (barbeque fuel) in LOX and throw it at the wall - it explodes spectacularly.....but again, disclaimer: DO NOT DO THIS )

 

Hmm better with Nitrous i think that the correct term for it ! ask Phatty he's just discovered its uses

p.s. Megasquirt will switch between 2 maps so i'm sure there are more expensive ECU that will do the trick.

 

nitrous is the same thing, but much safer - just adding oxygen with fuel

has anyone ever run nitro in a regular car engine? you should know this brooky, drag race boy

 

Yep..in a nissan sunny gtir

 

what happened? any particular changes to engine or map?

comparison of energy content of different fuels....check out nitro.....

petrol is well crap by comparison

 

I should change the maps but I didn't

What happens is that for a 50k engine you get the damage of a 200k engine don't try it No rings left ;p

 

petrol A/F ratio = 14:1

nitro A/F ratio = 1.7:1

so your sunny would have been massively lean - no doubt the cleaver ECU would have tried to adjust this but there is no way the injectors would have been able to flow enough fuel

lean, lean, and more lean = tatered engine; surprised it didn't just heat seize

thinking about this - if you need about 400cc injectors for about 250hp on petrol - on nitro, you would need 3400cc for Nitro. I dont think they exist......nitro dragsters must use carbs?

 

Yep i know that.I then rebuilt the engine and remapped it and..woooaaaa

I was surprised also ;p

 

as edited post above (No.34)- how did you get the injectors to flow enough?

 

I didn't use nitro as a fuel Rob.Just as additive using a NOS kit..

 

What management are you running on your seat btw?

 

very old fashioned Lumenition 451 - fuel and spark, without a crank sensor - uses dizzy for timing

but it works ok

not available any more so at some point I need to upgrade it to something more modern

 

ahh - I meant nitromethane fuel (as used in top fuel dragsters) - I think it would be a real struggle to get this to work on a regular road car engine
