Coilpacks On The Dyno

[3LGODZILA]

hey im wondering if its safe to do a dyno run without my coilpacks bolted down, reason for this is to save time, ill have roughly 1 hour to get the car on the dyno.. unbolt the coilpacks chuck some new ones on, then put it on the dyno again.

is there a chance the coilpack could pop off at high revs? and if it did what would be likely to happen? will i be risking my engine?

if it may be an issue i could always just bolt in one of the screws to save a bit of time.

Just leave the center valley cover off and unbolt them. The bolts only take a second or two. One bolt would be fine, and maybe that's what I would do. Worst case though, I don't see how it could hurt anything other than making it miss on the dyno.

i personally wouldnt say its your safest bet...so i'd say no.

Get your hands on a pair of the coilpack brackets, that way you only have to undo 3 (or is it 5) bolts and you can lift all of the coilpacks out at once, then have your other coilpacks already bolted down to the brackets and swap them over.

It'll take no more than 3-4mins to bolt the coil packs up, you only need half the bolts for a dyno run IMO.

So just do em up

if it is still running the cross over pipe you have to allow for removal and fitting of that also.

Why not bolt the new coils in before going on the dyno???

its all good... ill just drop my car off to the workshop and pick it up at the end of the day, get it done properly. instead of rushing to get 2 dyno runs done in an hour
