E85 For Stock Cars

[AngryRB]

Not sure if I can bring this up here, im thinking if E85 conversion on a stock car is worth while for a first mod or not... in my case I have an Ls1 SS ute and thinking wether a simple E85

mafless tune with OTR would be the best value and worthwhile mod to do.. also if you had a R32/33/34 wether an E85 conversion would be best done first...

Usually you do the exhaust, cold air intake , high flow etc but what would be the outcome with keeping stock and just converting the fuel system and running E85?

good idea or no good? thinking I could gain maybe 40rwkw with my ls1 using even a stock exhaust?

Running e85 in your ls will have you forever filling it up with basically no gain at all.

Ls engines pick up 40 kW no worries with tune and otr.

Mine went from 190 to 290 rwkw with otr, exhaust and 232/234 can (at 50 thou) and tune.

Plus e85 tune on most cars would require the added expense of injectors, probably making it less cost effective.

E85 doesn't have anywhere near the benefits on a n/a engine as it does on a turbo charged car

shit that was a good gain Ben, from what ive read on all the forums, they are have a shit tune from the factory, I guess I was thinking the E85 would allow the timing to be fully advanced and give it heaps more low end pull. I'm happy with it at moment, its an auto and I'm getting 10.7L/100km's which I think is brilliant as its a daily and attracts zero attention.

Goals for it is to pick up as much low to mid range torque and keep its good economy, was thinking E85 would bump it up to 15L/100km's but I guess the other stuff is needed then anyway.
