I don't know if it's normal, but I find my GT to rev really slowly. For example, if I'm at idle and I "blip" the throttle, the car doesn't really "stumble" but it doesn't really rev either. It may work it's way to around 1,200rpm and that's it.. It will also shake a little.

My question is: What can I do to get better throttle response?

Thoughts?

Thanks!!
Riley

Well, it is a V8... Throttle body/plenum might help a bit

The reason I got thinking about this is because I was driving my friend's BMW 550 and it has the SMG transmission.

I down shifted and it automatically rev-matched in like .2 seconds.. The RPMs shot from 2000 to 4000 faster than I could blink..

I realize it's a BMW, but it's not too much to ask is it? I think an engine like the 4.6 can do it too..

I noticed a difference in my throttle response after installing the WMS Velocity Tube, throttle body and plenum.

ive always noticed this also...would a TB/plenum really make that much of a difference? i can see it being slight, but nothing serious..

Along with throttle resonse it seems like it just finds new life (or more air) above 2800.

75mm plenum and TB would increase plenum volume and give you better throttel response...

200 bucks from RPM outlet

See now that's the ultimate goal. Does it actually give a lot more response? I would have thought the blower wouldn't be spinning fast enough at idle to make much of a difference? Not to mention that you have to spin the blower on top of a heavy flywheel..

Anyone with a KB have any vids of them "blipping" the throttle at idle?

Thanks!!

Agreed - also, my wife's 01 (with the T-45 and 10.5" clutch) revs faster than my 02 (with the 3650 and 11" clutch)...food for thought...

75mm BBK TB/P, K&N FIPII, Performance tune will get you a nice throttle reponse oh! and if you add 2 1/2' BasaniX system to it will sound good at the same time.

Rev down is slow on these engines though, there is mod that a few people on here did a while back so maybe you could have a look through the forum posts for the threads.
