Breaking in engine
 

Just got my engine back yesterday and I've been trying to put the first 500 miles on it so I can eventually boost in this damn thing. So far I've kept my rpms under 4k, and pretty much 0 boost. I tried not to boost or punch the throttle until I feel safe enough that the engine is broken in properly. Today I put about 300 miles from NJ to Philly, and I was wondering if the miles used are supposed to be street or highway miles? Or it doesnt matter just aslong as its miles?

I dont think it really matters..

Miles is Miles!!! :) Go a bit over the break in point of miles before you hit WOT just to be safe.

Well I'm in the same boat as you. They say it's best to have city miles because the shifting of various rpms at various times is good for the engine, to build up the compression ect... But I think it's fine driving the way you have. I have a question for you, see I only have about 10 miles on my engine. Does your engine still flood everytime you try to start it? And if not when did it stop? I hate/love the way the turbo sounds when it breaks vacuum and spools up...ahhh I just want to floor it. Also, how is your gas mileage, I went through 1/4 tank on those 10 miles.

Gas mileage is alrite, but this baby starts up great everytime. No problems with start up at all! One crank and its idling great.

Well after the first 500 im going to change the oil, and break in another 500 miles with a small amount of boost, oil change, than I'll be ready to run about 10psi. Right now I unhooked the boost controller so it runs at stock boost.

City miles would take centuries! :(

Did it ever flood? Mine has large streetport, maybe that's why it floods.

double post!

Alright you need miles period, City of Highway doesn't matter! But I would suggest that you go a littlre more than 1000 depending on your seals, Which type!

Well its a super street ported engine, no clue about the seals, but overall the engine is working perfect. Excellent compression, and oil pressure.

I can't wait to boost in this new turbo! AHHHH..

the "miles are miles" part isn't necessarily true.

with a fresh engine it has to go throgh several heat cycles in order for everything to seat properly. this involed getting the engine warm, and letting it cool off several times.

that is true for piston engines, not soo much for rotary engines! the only reason it is needed for the 1000+ miles is because if used housings are used they have a certain Wear to them, and you need to allow the seals to wear to the same shape as the used rotor housings! that is why compression rises! on a brand new engine with new everything you can romp on it and full boost it right away without any break in. I mean heat cycles has nothing to do with the seals conforming to the housings! Only killometers!
