What are the downsides of removing the Secondary plate from the manifold? Are there any gains? Has anyone seen Dyno Results from that?

 

Don't do it. Bad.

You can keep them open, an lose low end power,

or keep them closed, and lose top end power.

It's designed to be the best of both worlds!

 

lose power.

 

 

Just buy an aftermarket intake maifold like the skunk2(all motor), or the JG Edlebrock (turbo). I'm using the skunk2 right now, and below 4000 rpm you'll be pretty slow, but if you keep it above 4000 you'll be fast as hell!

 

What ALLMTRGSR said.

The stock GSR intake manifold is a pretty nice piece of honda engineering. You won't gain anything trying to modify it. The aftermarket single runner intakes do work but all the gains are in the top end (which is exactly what they are designed to do)

actually alaniz technologies modifies them and to good extent. thats why ericks racings gsr 1.8 liter na car is the fastest na honda. even beating out the h22 guys with 2.6 strokers.

 

Finally what ive been looking for ...i have posted numerous times on how to improve the GSR IM cuz i dont want to get the skunk2 and lose all my low end anyways......

So who is that company? Alaniz Tech?? Got a web site? I would love to know how to improve upon the already marvelous engineering of honda for the gsr low end plus up top!
