Hey all, last night I got to run with my friend's 01' honda accord v6. All I can say is i was impressed by it's huge top end band (80-120mph). He slowly but surely walked me three times. WX conditions were calm winds, and -3F. Anyone know any ways we can improve our "up top" and still maintain our high torque at the bottom?

PS - I took him by 2.5 carlengths from a standing stop

 

Variable intake manifold

 

Yes, i know we have one Maybe a more aggressively programmed ECU could make better use of the variable intake manifold. The wait continues...

 

I am no expert tuner, but from my expierence with bolt-on mods available for the I30 it is hard to get gains accross the power band. A Y-pipe is the only one I can think of that will help you pull stronger on the top end with out sacrificing low end.
My car is a dog(comparitively speeking) before 3k-3.5K rpm's then it pulls like a mad man.

 

A MEVI would definately help too. It basically prevents the power drop at 5k. basically at 5k it opens up the longer set of runners. There is a guy that has a source. His name is iansw. You might want to check with him on it.

He has a factory one. It's a 01 I30.

 

I'm not sure if you have mods yet... but a Pop charger with a mid pipe and a y pipe is a must. Don't feel bad, your I30 will always be more of a car than the accord that you see every half a block. You have more luxuries in your car which equates to more weight.

 

this is true JSL, you happen to know what the weight difference is? Id bet its somethin like 350-400lbs... that could account for it

 

exhaust components will help your top end power. So will a shorter intake like the berk intake.

What do you have on your car now?

 

Im totally stock due to MAF sensor problems. Im awaiting a fix to this, as i had an intake previously and it caused my sensor to blow. Im definitely not the only one on this board who has had this happen, and until there is a fix for it, or a specific intake on the market made by nissan that is dealer-okay'ed, im not gonna mess with the engine.

 

hmmm I've had a K&N on my car for 60k miles in different configurations without problems... I know that ppl who over oil their filters have problems. I doubt you'll ever see a Nissan Approved Custom intake... OE intake is your stock box, good luck in your quest.
