well after reading multiple people on the ls1 tech saying that this helps i gave in and got one. it is an airrade throttle body spacer. they all say you can feel the difference which is good enough for me. http://www.ls1tech.com/forums/ls4-fr...r-verdict.html
and also today i was changing my oil and did a quick FREE upgrade. flipping the motor mount. it seems that acceleration is more firm and responsive. quick and easy and free. if anyone wants to know how to do it just let me know and i throw a diy up on it. (yes i have the car out of storage)

 

Gonna be sweet, cant wait!

 

Without reading through all 7 pages of that thread- did anyone ever post a before/after dyno chart?

I'm not trying to bash, but just because people say it works, doesn't always mean it really does- you know?

Also- I agree with some of the people in that thread- that the whistling is probably bad (from turbulence)- if a gain is seen w/ a TBS, I'd try and find a smooth one.

 

Great to see your out of storage,

throw that diy up, will reversing my motor mounts on the 3.9 at the top help do similar as the ls4, I would have to flip two of them. If it helps I will do it!

Nice post man

 

I would like to see a DIY write up. I have been interested in flipping the mount. I also have the TBS on my long "wish list," but I will be getting the Hamburger one since it is cheaper and people have reported no whistle sound.

 

there are no dynos on that. i dont really ever think you will see them. the ones that i have seen have been on cammed ls4s, springs and rockers, and so on. so the only dynos that i have seen are coming in pairs of modifications. which if i ever make my way to one it would be the same way.

as for it helping on the 3.9 i would definately think that you would be able to tell on the motor mount flip. which that surprises me that you have to mounts while i have 1!!!!!!!!!!!!!!!!!!!!!!! craz gm.

 

If the engine mounts are like on my L67, its real easy to flip them. Look at the square mounts up top, on the radiator side. You'll see that instead of being solid, they're shaped like an I. What you need to do is rotate the rubber so it looks like an H.

So, take the bolt out of one of them, and rotate the dogbone out of the way (you may need to loosen the other bolt). Hose the rubber down with lube (WD40, whatever)- put the bolt/nut back in without the dogbone.

Then put your wrench/ratchet on the bolt and turn it (it needs to be tight already so it grabs the metal in the middle of the rubber instead of slipping). You'll see the square start to twist. Once it rotates 90*, put it all back together, and do the other one. Its really simple- 10 minute job.

 

what he said^^^^^^ ill take pics and arrow it up for easy doing for yall this sunday

 

Sweet!
