Octaine Boost

Post  easy78 on Wed Aug 12 2009, 21:36

Hi Jase just a quick question about octaine boost products i have owned a few turbo and supercharged high preformance cars in the last few years and found that due to the low quality fuel we have here in NZ if i ran some octaine boost every second full tank the engine ran better and cleaner and i got better economy and power.My question is would it be ok to do the same with my 1500cc supercharged seadoo .
Cheers

Many people think the higher the octane rating of fuel the better the fuel and the higher performance. This is not true. The Octane rating is related to the anti knock properties of the fuel, more loosly the speed at which the fuel burns.

Pre ignition (knocking) occurs when the fuel ignites before the spark plug fires which can destroy engines, anti knock or high octane is to prevent this and is often used in high performance high compression engines where the fuel tries to burn before it is ignited (non unlike a diesel engine).

If the engine is at manufacturers spec then use the reccommended fuel, if the supercharger is boosting more than standard there may be a case for higher octane fuel. To add octane boost will only waste you money.

I have a customer who who pushes his rxp pretty hard he said that he got better performance by using a octain booster,he was running 95 octain fuel and his booster
I told him to try bp 98 and see how that goes,he came back and said that it ran better than than his 95 and booster
I think it came down to him riding so hard that the engine was starting to knock so the ecu would start retarding the timing then by adding the booster helped with engine Knock(deto)
changing to 98 solved this by adding slightly more octain and kept the engine happy.
Now the race guys in the south island find that running 91 octain fuel out performes 95 or 98.go figure!
i have used octain booster in the old 2stroke days and found it to work ok.
If you find that using a booster helps go for it it wont hurt the engine

just do your research on octane boosters, some do next to nothing, I think the Nulon (from memory) one was good for about 2-3 octane points.
