gain on stock car in USA was dyno around 15-20 hp with our crap fuel our gain likely to be closer to 20 as we would be down a few hp due our crap petrol. @ Wayno had some dyno numbers from aussie cars |
This was in march, so OFT 1.5x era. I wasn't present so don't give me any credit.
You have to remember that if people don't customise on 98, you are further away from the full potential, unlike E85 which is tea parties and roses out of the box. This is why local tuners don't recommend tuning on 98, it's more work for them.
Stock 98 - 100-110 rwkw
Stg1 98 - 108-110 rwkw
Stg2 UEL 98 - 117 rwkw
Stg2 UEL E85 - 126-130 kw
Stg2 EL (stock header) E85 - 133 rwkw
The next one is in a month. Should have lots more tuned cars instead of cars with parts just thrown on. There will be lots of OFT vs custom E85 cars. Expect higher power figures due to later tunes and custom tuning, at least one NA car should be 140 rwkw. Basically the results from the previous day should be totally superseded.
If you try to do the "add up" thing, it's roughly like this...
Stock 98 = 105kw
Stg1 98 = +5kw
Untuned UEL 98 = +7kw
Stg2 UEL 98 = +10kw
Stg2 EL 98 = +12kw
Stg2 UEL E85 = +20kw
Stg2 EL E85 = +22kw
Header-back exhaust on Stg1 = 0
Header-back exhaust on Stg2 = +3kw
Air Filter = +3kw (not included in above)
Based on this old data on this particular dyno my AT with Stg2 UEL, OP, BPB, filter and stock exhaust should make 120kw/160hp on 98 and 130kw/175hp on E85.
