Dave,

                Just how much extra Hp do you think you got withy the upgraded Turbo?  I will be happy with 250 to 300 HP from the stock Hitachi.  Am I off with the fairys having this expectation?

Neil.

James,

I had my stock housing upgraded to TO4 by BNR Supercars.  They also have options for the Renisis. http://bnrsupercars.com/ Cost is $950 for the level 4 upgrade.  Makes a nice tight fit.  I had a big discussion about Turbo maps that you can find in the archives.  I settled on a TO4-H or TO4-E50 to top out around 350hp at sea level.

 

Attached is a turbo excel spreadsheet that you can use to evaluate various parameters in selecting a turbo.

James,

  2 flying that I know of – Todd  Bartrim and Dave leonnard.  Think they have the standard RX7 Hitachi turbo.  Just been around the world trying to get an affordable  turbo for my renesis which does not exist if you talk to drag racers etc.,  Quotes between $4500 and $6500.  Bought 2 hitachi turbos for $125 and one looks set to go while the other will need bearings.

                There was an offer of one in south Africa for freight only.  Would be a bargain.  Just hooking mine up now, but as usual much to go that I have not factored as usual.  Finally found an intercooler that may fit.

Best,  Neil.

Does anyone out there have any recommendations for a turbo (brand and size) for a 13b in an aircraft? 300-400 hp range. Reasons or experience is appreciated! Auto racers have their needs but are different from aircraft... or so I've heard. My 13b's are nearing the decision stage for turbos. Thanks, James Whitehurst
