ok here it is. 166.5HP and 182 TQ

This is with PRCAI, Budget ypipe, RT cat, warpspeed B and HKS muffler.
I guess my car is not a factory freak after all.

stock autos dyno around 145HP I hear. If so, this is a 20HP improvement at the wheels. It doesnt sound like much, but 20HP at the wheels is a big deal. And you get another 20+ HP with MEVI and ECU, which is even a bigger deal.

ps
I had 1 step colder coppers too. And 132k miles on the engine.

 

I think stock auto's dyno around 155 hp...and the colder plugs are def hurting your non-juiced power

 

You have just about all of the n/a mods and still have less than 200hp at the wheels. I guess I'll bypass the middle steps and just go for the boost.

 

Someone please tell me this is NOT right...I feel ashamed about my car now. I thought stock, people dynoed 160 to the wheels?

 

you expect to get 200hp at the wheels with intake and exhuast????
i think you bought the wrong car.
even a 5spd won't get 200hp at the wheels with these mods.

JsL, i think you are talking about the 5spd 4th gens, not auto's

hokiemax, the dyno doesn't look bad for an auto

 

who cares what they dyno at...they obviously put whatever power they have to ground veerrry effectively..

NOOOO.........Now I really want a 5spd swap!

 

That's about right for an auto

I dynoed 165 with Y-pipe and PR CAI on my 97

 

TQ numbers are nice.

 

Stock 4th gen 5speeds get ~160 HP to the wheels. Stock 4th gen autos get ~150 HP to the wheels. Some engines are stronger than others, and I've seen autos range from ~145-153.

Even a 4th gen with every single normally aspirated mod available (VI, y-pipe, cat-back, etc) is going to get 200 to the wheels. Best we've seen was 195 at the wheels. Even n/a 5th gens with the more-efficient variable intake only dyno ~205 with all the bolt ones.

The only way to get well over 200 HP to the wheels is to buy a 2002-up Maxima, drop that engine into your pre-2002 Max, or super-, turbocharge, or add nitrous. There are definite ways to get well over 200 HP with a pre-2002 but it'd take innovative, custom work such as a stroker kit (using the VQ 3.5L crank/rods) and cams (actually not custom, avail from JWT now but are $$$).

 

I guess my point was that if you are looking to get 210-220 at the wheels your are out of luck, s/c or turbo will give you alot more than that but for alot of money.
I dont like nitro either, I only wanna fill up gas.

here is the mod chart:
1) upto $1000 (all bolt ons) 150-166hp
2) upto $2000 (nothing) 200-210hp
3) upto $4200 (boost) 250hp and up

so there is a huge gap in the middle of the mod spectrum.

 

i thought so too. actually i though my 5 speed max was bout 175 to the wheels

 

Some Math examples
Stock 4th gen 190hp

15% loss = 161.5
17% loss = 157.7
20% loss = 152
22% loss = 148.2
25% loss = 142.5

I'm not sure on exact numbers but I believe the manuals have about a 15%-18% loss whereas the autos have about a 20%-25% loss. Don't quote me on the percent loss, but you get the idea.

 

they do not make ECU's for 98 maximas....

 

Hey HokieMax, you down in VT now or you in town? NoVA Max meet Sat, Feb 8 at Tysons. See anyone there

 

I wish I was down in VT. I live in tysons now.

 

I was thinking of getting a head job(this would certainly make my day if you know what I mean). I was quoted $400 from a junkyard for the complete cylynder head including the cams and intake manifolds.I could have gotten it poorted and polished, and had the cams done for maximum lift and duration. Combined with all those bolt ons, this should make substantial power. You could even go for custom pistons while you are at it.

 

Whats it take to make that possible?

 

If you use your existing head instead of buying another one, it will cost $2000 or more but I'm sure the gains would be worth it.
