5500 Rpm

[midnightsliding]

i dunno why my car dose this but maybe u can help.. i have replaced my KA with a lower milage KA and i have removed the sendary butterfly valves.. but my car is stock open header right now, the car pulls real good but, when i hit 5500 rpm's it starts pulling harder like v-tech or something i dunno why it dose this, i have 2 friend that have intake and ehaust and i kill them and their cars die after 5500 rpm, i was wondering if my TPS could be off or somting. i would like it to to this hard at all times.. It might just be me i dont know but if u know anything feel free to replythanks

Maybe your cars just faster???? I know when I ran with a straight pipe it felt like I was still pulling after 5500, then when I got a resonator put it dies after 5500. I dont think resonators hurt performance so the only conclusion I could come to was it just sounds like your goin alot faster than you really are(honda syndrom) But Im about to remove my secondary butterfly, Im glad to see it makes a difference. Also why fix if its not broke? Your pulling hard so just leave it.

yea ur right i was just wondering if i could get it to pull that hard through out the Power band.

My car does the same thing at 5500rpm. My butterflies are still in.

[driftn240]

by secondary, are you talking about the swirl control butterflies?

[midnightsliding]

i dunno i have always herd of them as the 2ndary butterfly vlaves. but what ever their the one in each of the 4 runners in the intake manifold...................................................................

could be a coolant sensor problem. Check for yourself:

like when it hit 5500 it get really loud and pulle harder, but i cant really tell u what it sounds like im still running open header. but with my stock ehaust it still did this at 5500.

the reason it seems to pull harder at 5500 is because thats when your torque peaks, and your horsepower at that rpm is rather high too, making it pull all the way up to about 6700, thats when i shift mine and usually it works pretty good.

my car does the exact same thing, my friend said it reminds of of *gasp* v-tec, i dont know if that is good or bad lol

[midnightsliding]
