Post Planning on dyno - tie down points?

I am planning on doing a dyno on my 86 with LBE and APE v2.7. Where are our tie down points? I don't want anyone to f*ck-up my suspension.

Thanks

Eugene

I have two Black Hooks in the rear. One comes out around the area where my muffler shield used to be. and another on the opposite side. If you have those, that'd be perfect?!? <img src="confused.gif" border="0">

I've heard of a BMW M3 bending it's semi-trailing arms on the dyno because of the tie down points.

I'll be dynoing my car late this month too (hopefully), I was planning to use the torsion bar housings, but that may not be the best place it seems like. Another commony used place is the front tow hooks, but those also don't look too strong, I'm not sure if they'd hold up...

What are other people using?

When I took the 951 to get it inspected then backed it up on the dyno but couldn't find any place to strap it down. "Well I could just dyno it like this but it would probably fly off and that wouldn't be safe." Retard mechanics. They just "sniffed" the exhaust and got it to pass and print out the sticker. This is in NY.

My M3 did get the rear control arms bent b/c of the dyno straps. I went ahead and changed to adjustable aluminum rear control arms.

Of the cars, the M3 is the easiest to drive on the track, the 951 has the most grunt, and the 996 cab has the most sunshine-fun factor. I cannot believe the torque of the 951- feels like my old 78 T/A 6.6 street rod when on boost!

I had the dyno guy put a strap around the rear trailing arm next to the rear shock. Be very careful that they do not wrap around any brake lines!! I had no problems develop from this. Good luck.

gene-

are you taking it to Shalala (there in the same complex as viking) for the dyno?? Last time I was there he was dyno-ing another 951 that looked pretty stock (so probably no special welded in hooks), but I'm not sure how he had it tied down. Sam is very good (as I'm sure you know), so I would think he has a good idea of how to do it without damage.

If they use those wide-thin nylon straps with the ratcheting mechanism, you can actually thread the straps through the edge between the bumper and the body of the car. Then re-attach to the ratchet and tighten it down.
