Running aviation fuel in an N/A......How would the car take this being standard with only minor mods (zaust, cold air intake and adv. timing)????? What would be needed for it to run it if it wont run off avgas to start with???.....sorry i dunno much about avgas.....its just i have plenty of drums of it (about 10 20 litre drums) lying around in my garage for our race car.... :twisted: :twisted: Some original photos have not been recovered yet.

Yeah an n/a VL should run on avgas....... for about 20seconds..... i aint no expert but i do know that avgas burns at preety high temps and the compression is far to great for a stocky..... If ya want that power probably safer and cheaper to get a small NOS kit, engine will last a little longer....

I know of a bloke that runs 50/50 Avgas in his harley. Ask Mr.VL he should know more about that. I really wouldn't think Avgas in an atmo would be good for it, avgas burns at very high temp for the point of not being too cool at high altitude in a plane. Anyway i would only go probably 25/75 Pulp/Avgas

Hypothetically Speaking: I ran Avgas in my N/A vl, it had about 10% PULP. I only used 15 litres of the stuff and advanced the timing very far (without a timing light) and it didn't ping cos its avgas aye. PROS: It ran very well and definitely performed a tad better, I'd only rate the performance gained as similar to a cold air intake or something minor like that though. CONS: much much lead......this is bound to wreak havoc on numerous things in the VL that were never meant to see lead. If caught I think the fine is above $100, 000. dont ask me how theyd catch you though. My fuel lift pump is now very noisy, sounds a little blocked maybe. Engine still sweet, no problems.

Im pretty sure ya not supposed to run Avgas on a vl coz vls run on unleaded and the lead in avgas burns out ya cat converter. Thats why leaded cars dont have cat converters My car has a 2 1/2 inch pipe through my stock cat so it should be right either way

ahh yes true true......didnt think of the cat :roll: Ill take off my hiflow cat and put on my old gutted cat if i do end up running some avgas......oxy sensor needs replacing anyway, so ill buy a new one then run it with my old one still in, run all the fuel out and put new one in.... I wont be running pure avgas, ill be mixing say 25%avgas 75%pulp....
