Estimated HP?

[KN6_GTR]

Hello everyone, I am new to the forum. I’ve been lurking SAU for over 3 years now reading stuff and finally decided to make an account. I am currently stationed in Okinawa japan. We don’t have a dyno here and was wondering if any experienced members here could tell me what kind of horsepower i can expect from my build with a proper dyno tune. Am running a street tune Atm. Thank you for your input!

Do some logs with the Haltech, dowload into Virtual dyno software (free).

Thats the better option than wild guesses.

very nice looking car, would definitly be fun!

Thanks for the info! Didn’t know software like that existed!

Most of that mod list makes little difference. Your limits will come from the injectors/pump, or the boost limit before it knocks.

You can work out how much air the turbo will pump at different boost levels if you have the speed sensor installed (and connected to something that can read it). Otherwise, you can look at the RB26 dyno results thread for other RB26s with the 8374 on, (https://www.sau.com.au/forums/topic/93880-rb26-turbo-upgrade-all-dyno-results/) or the BW EFR thread here also.
