Yesterday I dynoed my recently installed JDM-intake manifold. Instead of having power drop off like an anvil at 5400rpms, my power carried straight to the 6500rpm rev-limiter. I gained ~7fwhp (189fwhp now) and overall I gained 53fwhp and 46fwtq at 6500rpms vs the stock manifold. I'm pumped to say the least. I had no idea this thing would make such an improvement.

Wow, quite a gain if I do say so myself! Don't forget to update that sig now, what are your new peak #s?

Umm... That's most definitely not cool!

I thought I told you you weren't allowed to do outstanding mods like that.

It really looks great. That's quite a top end change!

Makes me wonder what another 500cc's would do for me. Hmmm....

My new peak numbers are 189fwhp@6000rpms and 186fwtq@4500rpms vs 183fwhp@5400rpms and 193fwtq@4500rpms. The great thing is the power holds on till 6500rpms (183fwhp) instead of dropping like an anvil at 6500rpms (130fwhp). I ended up loosing ~7fwtq as you can see on the graph. Somehow the new manifold lopped off the two "bumps" in the torque curve where I use to make my peak torque. The torque curve is much smoother though.

My next mod is an upgraded ECU which will extend my rev-limiter to 7000rpms and add ~10% more power from 3000-5300rpms. The extened rev-limiter will allow me to take full advantage of this new setup.

Last Friday, a 97 Maxima with this manifold, intake, Y-pipe, and slicks ran a 13.99@98mph with a 1.99 60'. His prior best before the manifold was a 14.4@95mph. When he gets an upgraded ECU he might be looking at 13.7-13.8s.

I really want to test out the setup, but my RPM switch (Harlan Engineering) that activates the solenoid to open the butterflies has been flaky. It was only opening the butterflies in 1st and sometimes 2nd. When I dynoed, I was had a toggle switch wired to the butterflies. Hopefully I'll get the switch back before KCIR closes this year.

I'd like to see what your LS1 does at KCIR.
