3.4L bottom end

[ForceFedV6]

anyone have any idea how much power a 3.4L motor's bottom end can handle before it goes bust?

no idea, crank up some boost on her and see what it takes. :)

Re: 3.4L bottom end

well, right now i'm running a powerdyne with the 6psi pulley and i just ordered a 9psi pulley. But i was thinking of possibly running some go go juice as well with the blower. I just wanted to get an idea of how much power i could force out of it. Is nitrous a bad idea with the blower if my motor's not built for that kind of a setup?

I've been running 15 lbs of boost on my stock bottom for years with no problems. Use a good synthetic oil 10w -40 for some added protection. I wouldn't go over 400 hp with only 2 bolt mains.

damn, 15psi of boost, well I guess I have nothing to worry about then, thanks for the info

Re: 3.4L bottom end

I would suggest under boost plenty of fuel, retard timing and I've always ran an intercooler and water injection to keep the pistons happy.:rock:

Without an intercooler (ever try to stick one in a Fiero?) I have run 13 psi with no problem at all for many years.

Stock crank and rods but forged piston set.
