Its good if you drive full throttle alot, only slightly worse then then the simplest efi systems.

I want to mount it to the track and drift what is the power gain? with an engine GRA now I ride with an injection of origin

Above 170hp, the stock intakes are restrictions so you can win more. Under 170hp? Ehm..not much.
From what I've noticed, the best you can hope for is around 10% benefit from intake and exhaust tuning combined. So worst combo will give 170hp, best combo 187. Realistic estimate is around 6% with a wider torque curve (more hp over the entire curve). Real power comes from from the cams mostly .

From what I've seen, FCRs are expensive relative to IRTBs for the 86..and fuelling will be better with EFI. So other then the coolness factor, you will not gain much.

They are pretty cool though...too bad that coolness only helps on internet forums and not on track.

Don't know about theory but my car, after intake/ecu/injectors change is much faster than stock.
Exhaust, head, cams are stock and "not even touched".

Haven't dynoed it, but acceleration and top speed makes me assume i have 10-15 bhp just with intake and different map.

hi..

Somebody could get information on the settings to have bases for rcf

thank you

Not likely, you would be the first in Europe/the west. Maybe some motocross mechanics can help you. They use them a lot.

Wrong, one of my friend already have FCR on his 4AG. (since 3 years now)
164hp with HKS 256°.

I will not give any details about his setup here because a guy does not deserve it.

You could have just mentioned this without the last remark, nothing good will come of arguing on the internet.
