Out dynos read diffrent to usa


Stock car here does about 110kw at wheels

Header and tune on petrol about 125 kw
Header tune and e85 about 135 kw


Our petrol is about USA 91, so if your on 93 petrol you will already be closer to the e85 power outputs


European 98 ron petrol is better than Australian 98 so you wont get as big a jump to e85 as in Australia

Aha! From the looks of the fasteners on that control arm, you rescued it in plenty of time.

I had a ton of soot and it even was shooting behind the car onto the ground in the garage as I warmed it up. That was with aftermarket UEL header, over pipe and OFT.
I had a member in here, Tor, adjust the tune and it went away significantly on the tail pipe and no more on the ground at all.

Ah I see, except from E85 being cheaper I wont notice a huge difference between E85 and 98 then.

It’s actually more like break even (at least in my area) cost wise due to the MPG drop with E85. For example I get about 250 miles on a tank of E85. I am completely stock with the exception of E85 and it’s a very noticeable increase in power. I don’t think he was saying it isn’t an improvement. It just isn’t as big of an improvement if you are going from high octane fuel to E85 vs lower octane fuel to E85. In my case I went from 93 to E85.
