Hahn is a 2 piece hot side pipe?

 

3pcs

 

weird

 

new transmission mounts are in.

 

looks nifty

 

looks good, works good

 

I made a signature! finally... lol.

Need to change it now though

 

So after driving on the new mounts, I can definitely say they really help with grip A LOT. Good investment.

 

Powells would help more....

 

He's broke can't afford Powell stuff

 

Burn.

 

Im not knocking powell but for running nt555 on the R I dont get very much wheel spin at all in 2nd. Honestly they do the same thing. It raise the rear of the engine up 1/4" and solid rubber mounts are nice. Cant complain what so ever.

 

BUT

until someone shows solid proven data, same amount of rear engine rotation, same car, driver, track and actual comparison of times and powells having better times than zzp, youre all just nut swingin.

 

is it the raising up that helps traction or just keeping the engine and trans planted and not twisting from the torque and wigglin' about?

 

this is what broke people do...

 

It's a rotation of the entire assembly (engine and trans) to align the axles better to prevent wheel hop due to axle angle. Powell is the one who worked with GM Perfomance in developing a different mount due to the Cobalt platform being initially engineered to function better with automatics.

 

For awhile (maybe zzp changed their design to match Powells) zzp's mounts where just a direct replacement of the stockers with firm bushings and didn't actually rotate the engine to the position it needs to be.

 

good to know. I know they have ss/sc kits but I thought seeing that they weren't listed for the tc ss cars they had fixed the issue.

 

zzp has the spacer for the rear that does 1/4" on the gen2 spacer but now I see they have a gen3 spacer that does 3/8"

 

The arbitrary spacing isn't going to line up the axles right. That's where Powell's comes in, his adjusts the engine, in the front and rear mount, to the correct angle to line the axles up.

 

explain your reasoning because it did raise the rear of the engine and rotate the engine forward and it has made a huge difference.

 

I'm not going to explain geometry to you, let along suspension geometry. I'm not saying it doesn't improve the angle, but there is a sweet spot and Powell has it. If zzp offers different spacers they aren't basing it on lining axles up.

 

I completely understand suspension geometry. So really there is no proof that the zzp mounts are worse. Zzp has continually ran fast times at the track with their mounts.

 

Also, the only difference between the 3/8 and 1/4 mounts is the 1/4 is same mount size as stock with a spacer, then the 3/8 is a bigger mount without a spacer.

 

I have had both, and will say I had more vibration with the ZZP mount by far. The ZZP mount was better than factory probably because it didn't allow much movement. The Powell mounts I have now though are better. With the same tire arraignment I could get wheel hop using the ZZP setup, have little to none with powells. ZZP mounts are pretty though.
