...?

**JamesMcbride** · 13-01-2003 07:06

no, the fuel pump relay just turns the pump on and off.

**ronald** · 13-01-2003 07:41

Maybe your injectors are just to big?

**Matheus428** · 13-01-2003 13:34

..for tips friends.

I think i found the problem, is in spark plug wires, the high temp of exaust manifold, damage the wires..i will check more correct. Thanks for tips friends.

Mate you are off ya tree! 1050cc/min would power a evo to nigh on 800bhp! lmao

**Matheus428** · 13-01-2003 13:41

no man..
alcohol engine get more rich mixture than gasoline, is like 30 or 40% more..
And in my case, i didn't work in fuel injection chip(my fuel injection is Le-Jetronic), i only make correct the mixture in high boost with injectors and rising fuel regulator.

**DarrenH** · 13-01-2003 13:43

maybe yuohave 800bhp matheus, thats why your tyre burn lmao

**Matheus428** · 13-01-2003 14:06

..

**Matheus428** · 13-01-2003 14:10

and with this injectors, i can use more than 1 Bar(around 1.3BAR, i continuos can use this injectors), without extra injector..

**RDS** · 13-01-2003 14:21

what fuel pump do you use?

**DarrenH** · 13-01-2003 14:49

oddball thinks your calculations have taken a bad turn, oddballs car makes 200 n/a bhp with only 253cc/min @ 3.5 BAR fuel pressure

lmao, his car must do like 10mpg everywhere

Yeah Oddball says correct.. for Oddballs engine 253cc is suficient, because is a gasoline engine, and N/A. The turbo engine get hotter the air(because this with intercooler, don't need so rich mixture), and you need a part of fuel, for get colder the chambers.

Look the formule for your engine Odd(this formule is for turbo engine, then, lets suposse you using 1 BAR of pressure):

Vi= 190(your sbd kitt power) x 5(the specific consumption for your engine/CR, fuel gasoline)/ 4/1(your possible turbo pressure) = 237,5cc/min.
Really near of your case.

Have more precises formules than that, that consider the temperature of air the engine sucking, and etc.. but i don't have this formule really now.

**DarrenH** · 13-01-2003 15:36

ok, but oddball doesnt understand. If you use alcohol fuel, surely you need less total fuel compared to straight petrol.

alcohol is more efficient, better burn, so you need less fuel ? 753cc/min is HUUUUGE amount.

**Matheus428** · 13-01-2003 15:43

No Oddball... .not not..not..

Alcohol is less efficient than gasoline. Gasoline make more energy with the same amount of alcohol. Because this, alcohol need work 30 to 40% more RICH. Alcohol make more power than gasoline, because work in high CR.
The air/fuel ratio for alcohol is 10 parts of O² for 1 part of alcohol, the gasoline is 13 parts of O² for 1 part of gasoline.
Because this, the specific consumption of gasoline engine is less than alcohol engine.

**DarrenH** · 13-01-2003 16:06

aha, now oddball is understanding.

**^Trickster^** · 13-01-2003 16:35

there brazilians are too clever for my liking lmao

**Matheus428** · 13-01-2003 16:46

hahahahahaahahahahahahahahahalmao

**Matheus428** · 14-01-2003 00:43

the problem is in the distributor!!!! much oxide in conectors!!! i clean, and engine comes ok!!!!

uhauaha.. damn..

**DarrenH** · 14-01-2003 00:49

matheus, do you know what this means ? someone sent this in a message on kazaa, translator web site does not make sense of it.

ME LO DAS ASI CHATEAMOS

**Matheus428** · 14-01-2003 00:53

uahauahauh.. its in spanish Odd.. my natural language is portuguese. Is diferent.
But i think its mean: "me, will disturb you"..

**DarrenH** · 14-01-2003 00:56

yeah i knew it was spanish, the man sending the message was talking to me in english, then he asked me if i had an e-mail address, i replied yes but why, and then he reply with the above message in spanish.

I guess it was rude words, and translator does not like them !

**Matheus428** · 14-01-2003 00:59

hehehe.. he doesn't liked you! uhauahauahlmao

**DarrenH** · 14-01-2003 01:02

or more likely he DOES like me, if you get my meaning. I have blocked all further messages anyway. lmao

**Matheus428** · 14-01-2003 01:14

heheheh..good way..
