Throttle response...

[SupraSith]

Ok. I already have a lightened flywheel, upgraded exhaust (3 inch straight thru), K&N air-filter, and 550cc injectors. What other mods can I do to increase throttle response.

It still seems like I stomp on the pedal and there's a second of delay before the rpms move. Upgrade the throttlebody? (cruise control is toast anyhow).

Or maybe this is just a tuning issue?

My dads 88T does the same thing, its horriable.

Aluminium drive shaft should help but I don't know if that is your problem.

Whats the story with the 550s? What other mods do you have that support them?

I don't have any problems with throttle responce really. Probably could be improved by a JDM TB but for stock linkage its fine. Sounds like something is wrong on your car.

heh check your throttle cable and linkage. make sure you dont have any free play. That can have an effect :naughty:

 

[americanjebus]

yea check your freeplay, i had like an inch of freeplay that was a REALL killer when it came to launching.

Boost leaks. Pressure test your intake tract!

Hehe....there's always the Front Facing Intake Manifold modification. That with a JDM throttle body that uses just the pull cable instead of the gay USDM linkage will definitely increase throttle response.

But then again....that's a lot of work and this isn't a practical response.

Another thing is the stock exhaust elbow. That thing is horribly restrictive. Also, port and pollish the exhaust mani.
