dyno results - more power

went to the dyno saturday morning. the only power mod i have had done since my last dyno run is removing the intake resanator and a custom 2.5" mandrel bent cat back piping.
180.2 hp and 191.1 tq compared to the last run of 173.7 hp and 187.2 tq. pretty good gains for only $156.30. my goal is to clip the 200tq mark. i figure a underdrive pully and putting the factory 15s w/nitto 555r on will get me close. the most amazing thing is that i am making 170lb ft of tourqe at 1700rpm! hp starts low at 1700rpms and builds smoothly. i also want to find a se ecu cause so i can get rid of the speed limiter. the horsepower doesnt seem to signifitly fall off when it hits 120 mph. i know there isnt a lot of power past 6000rpms but i would like to see what happens. i made two runs in fourth gear and one in third. third gear came up with the same numbers. which is good.

How much HP do you have to the front of the car A.K.A. the kind of horsepower all the manufactorers rate the cars when they make them.

all this dyno talk is killing me... I'll have to dyno my car soon... I think I must be also to 200 at the wheels... when I launch now my front pulls up a lot and my rear spoiler is rattling like crazy yet is is still on there really tight... I'll have to try and get that on video...

You just happen to be able to put the power down to the ground a little better than most. If you had 200fwhp you'd be close to 14.0s.

i am curious what percentage of horsepower is lost from crank to wheels in a stock auto maxima and if this percentage is lower than the norm for auto v6 sedans. i have driven a galant gtz auto which i believe produces approx. 195hp and weighs about the same as a max. it felt very sluggish compared to a maxima.

Why not? I find it very hard to believe it could actually make you lose HP anywhere because all it is doing is slowing down your ascesories{AC,Alternator etc.}. Explain the philoshphy behind loosing HP by doing this? It makes no sense..

Thanks Medic.

What are the negatives, if any? Decreased gas mileage? Drivability probs? Noise increase? Thanks.
Is it easy to do? Easy to put back? Thanks again.

Sprint, thanks for sharing your views but I have all ready ordered a UDP so I sure hope it does something..

As for the regular resonator? The Idle Air Control is attached to it, and that (the IAC) is vital to a smooth idle. My question becomes, 'Where would you mount it if you take the box out?' Answer: Don't know.
As for drivability problems or decreased gas mileage, I also don't know. It seems to be of little benefit to remove it.

Well, the '95s have an additional resonator that isn't present on the later models, its attached to the intake, and what does it do? Don't know, its a sealed box that leads nowhere. The ram air duct delivers air closer to the intake, assuming the stock airbox is still intact. I would imagine that it plays little effect underway, but is helpful while stationary.

check out http://maximadriver.com cheston used to have some graphic displays of dynos comparing the stock ecu vs the gforce ecu. this will help explain what i described above.
