yah so that motor i posted up i got it running finally.

-yes i kno the valves are loud, i never checked, been adjusted since.

here it is. hope to hit the dyno soooon!!!

like i said i adjusted them, its quiet now. some of them were at .011 way outta wack

 

damn a 20 liter GSR?

Imagine the rod ratio on that mother...

 

p.s. just watched the video.

Was that really the first time you started it?

yep, thats why it is stil covered in parts and different timing belts i was just trying, it cranked over ok with no fuel/spark and i fired it up.

 

Have you read any of the posts about engine break in? What method have you decided on using?

yes i have. i have some castrol 5w30 in it right now, i took it around my block once to make sure everything is ok. and once i put about 50k on it(driving to and from exhuast shop), changing the oil and going right to the dyno.

edit: is that a good method or is there something else you can suggest?

 

50k??? holy breakin batman and a deckplate for only 2 liter?wow good luck with your project

I think you mean 5k

 

Your suppose to start the motor to see if it runs then, through on a wide band make sure a/f ratio is in good shape. If it is good and you know how to tune then go, but if you dont have it towed to a dyno tell them to throw on a break in tune, witha rev limit of like 4500 rpm. then drive around on that for 500-1000. then bring it back to get it fully tuned.

 

I think it was supposed to say 5 or 50 miles not K.
I put about 5 miles on my motors then take them to 10krpm
That slow break in stuff is whack, all the motors we have done that way leak down 5% or more. all my hard breakins leak down 0-1%

Where did you get that crazy plan?

no i actually mean 50 kilometres. thats like 30 miles i guess i donno. just to make sure everything is good

 

Then it may already be too late.

Obviously you didnt read the break in threads.

All you need to tell "is good" is if you have any leaks, set base timing, make sure nothings knocking. Get it to operating temp under NO load, then shut her off, maybe recheck valve lash when she cools down and tow her to a dyno.

when did i say i drove it that far?

 

seating the rings happens within the first couple minutes of driving. wether you like it or not. how they seat depends on you. for a good ring seat, rpms need to get high with the throttle closed to create vacuum in the cylinders. the most common method: 2nd gear, 40-60 mph, full throttle to 60, closed throttle to 40. the closed throttle part is the important part. repeat this 10-12 times. but its probably too late for this as previously stated. and if it breaks at high rpms within the first couple of minutes, u did something wrong. gaskets do need to seal, so after the break in is when u should be gentle with it.

for sure. When we break in our race motors we run them for about 20 minutes and then take them to the track and do a couple 1/2 passes. Check the plugs and if everything seems right it's ready to go to 7k (mopar 340 v8 so that is kinda high rpm )
