not good for valves, not good at all. unless you want them to cool quickly, expand, crack, chip, and eventually disentigrate that is.

@Bamchucknorris to what degree does one need back pressure for valve cooling? will it fuck up the valves if you run a straight pipe without mufflers or cats? and how will it affect the valves in a petrol vs a diesel engine? your input would be much appreciated. since i can't find a clear answer to this issue.

[Bamchucknorris]

@silvergate3909 For my small engines, I make sure my pipes end far from the exhaust flange of the head/rotor housing (mazda rotary engines). For example, I'd at LEAST have a foot of tubing for a 350 chevy because when the engine shuts off, cold air will begin to flow through the pipe (from pressure differences) and they will reach the valves soon enough. With a muffler or cat, I wouldn't worry. Just make sure your straight pipes extend outwards a little bit. It also deepens exhaust sound.

@Bamchucknorris Thanks man, I appreciate it!



[Bamchucknorris]

@silvergate3909 As for petrol vs diesel, valves are valves, but in diesels, heat is required for combustion. Therefore, diesels might run a little hotter and the valves will take longer to cool. I'd recommend a longer pipe for a diesel than gas.

@Bamchucknorris Thank you again :)

I WOULD put that in a FORD CAPRI ....AWESOME ENGINE

[Brockie777]

Wow, you got that thing to idle properly!

aait loopt lekkker joh

boeruhh

[AutoCalculator]

Cool vid..but wouldn't the engine go better when inside the car :~)

[Elefant95]

Also can you tell me, if the Lister Le Mans 7.0ltr V12 uses carbs or injection and thanks for the vid.

[samandlauz]

Do you mean the Lister XJS? That had a 7.0 litre twin supercharged V12. I think it was injection as well.

[Elefant95]

For producing engine music like that, you can't go wrong with an all mechanical V12.

[Elefant95]

What modifications have you done besides the carburettors to make it sound like that & produce 400bhp.

[milofare]

Open Exhaust manifolds? a good way to jack up the valves!

[ntprofile]

I was thinking the same thing.

[BertOlaB9]

Nice, I hope I get my motor sounds as good when completed. :)

[DaimlerDouble6]

Awesome motor, the link doesn't work though.
