LS4 Performance - Vector MS Heat Soak Reduction Kt

Hey everyone I'm wondering what everyones input is the Vector MS Heat Soak Reduction Kt for our LS4?

Is it worth it on our cars and will I see an improvement with the engine?

I'm also looking into getting a Power Aid TBS and wondering if its a benefit on our Ls4s also. I one on my 04 GTP Comp G and did notice it kept the throttle body cooler since it seperated it from the intake/super charger and also gave me some more throttle response.

I'll be buying both parts off a forum member at a discount so I wont be paying full retail.

Any info would help

Thanks,
Dave

TBS is a serious waste of money on any car with port fuel injections (ours).

Some folks have claimed to feel a difference, but no one has ever proven the results on the dyno.

I can offer some firsthand experience: We just put a 78MM plate nitrous system on my Camaro. This is basically a throttle-body spacer with nitrous jets. When we re-dyno'd the car without the nitrous on, it made within 1 HP of a previous dyno pull.

Unless you're getting the TBS for $10 or something, IMHO, it's just not worth anything.

I had read iirc on gmls4 somewhere that tbs on stock LS4 manifold did make a difference because of that oil thing that protrudes in the opening of the manifold itself I will go look for that forum

I have the IAT relocate kit on my car... it works well and makes a difference.... TBS as mentioned above, is a waste....

MSD has an IAT sensor for $20 something. Requires a lil electrical work. (just have to cut and splice the wiring harness) if you really wanta do it on the cheap, I think you can get just the sensor for $5.

Can we get a pic where you installed yours. Thanks Lew

First hand experience is hard to debate :)

I have always thought the TBS, not just our engines either, are poop.
