[ash mi16 0]

not sure if this is the right place to post but anyway, im puting a cammed 2.0l mi16 engine in my 205 gti and it on twin 40 delortos, it got piper cams, i dont want to over rev my engine as it was onlt rebuilt last year so wot would it be safe to rev it to? i dont no wot a standard mi16 revs to? let me no thanks ash

If its on standard rod bolts, then I'd say 7250 rpm to be safe.

yes it is mate it had a full rebuild last year and was fitted with piper cams and had the head ported and polished thanks

Regardless of the head and cams, it is likely that the thing that is most likely to let go at super high revs is rod bolts, hence my comment.

yeah i no mate would it be better to get some arp bolts?

7400 should be the absolute limit with hydraulic lifters. The valves will bounce at 7500 before the rod bolts let go.

Mi's are fine up to 8500 on std lifters, just the rod bolts as said, My old one used to run to this all the time,

It was fine, Was quite surprized as everyone said the same thing about the lifters but to around 8000, so you;ve got to push these thing's further

mine is a 1.9 mi16 engine, lightened balanced knife edged crank, lightened flywheel, piper cams with solid lifters and that revs to 8500ish, there is no mention of arp bolts in the rebuild and there are receipts for everything so i assume they were not replaced, i set my omex to 7500 in the old car and it was fine.

sounds good mate i just dont wana over rev my engine as it was only rebuilt last year :/

[petert 588]

Over revving is one thing and having hydraulic profile cams that will actually make power past 7500 is another.

It was a freak engine, Peak power was from 7500 till about 8k from memory as it was a while back now, that was on a set of Kent regrind's,

But back onto topic, I'd get it on a RR then you know where the power is made and to check that it's running OK as 40's with smaller chokes would be on the limit
