With all the bolt ons for the 4th and 5th gens(2000-2001) what would be the bhp and/or fwhp for these gen cars all the way hooked up NA.
Just wondering because now with VI i think that they should be close.

 

friend dynoed at 192 FWHP on his 2k with CAI, y pipe, hi flo cat, catback, and UDP (also eibachs on AGX's, but i dont think that effects dyno results)...anything im missing in regards to bolt ons?

err this is an auto

 

ECU, SAFC, CAMS
Those would affect its NA performance.

 

never seen anyone bother with cams on an NA max

 

Well they do help on any max. Just are twice as good on boosted maximas. My whole point is to see if the 4th gens can get the same amount of hp as the 5th gens with ever mod possible. I know I have seen 4th gens with around 192fwhp.

 

have u taken a look in the dyno forum? i believe a 4th gen w/ intake/y/exhaust cat, ecu, VI, bla bla bla bla would be around 200 hp @ the wheels, if not slightly higher?

 

There's only a few 4th gens who have touched the 190hp mark N/A. Keven97se I believe has the highest, at 192hp. That was with a ported and polished intake manifold, and then I/Y/E, maybe UDP as well I'm not sure. MEVI doesn't do a whole lot for peak power, about 5hp at peak, its past peak hp where the MEVI shines. Most typical 4th gens with I/Y/E/UDP dyno between 185 and 190whp. No one's gotten 200hp yet, though with MEVI and a JWT ECU it might be possible. I think cams are going to be the key to getting a number of 200+ whp 4th gens.

 

The power to weight ratio hurts the 5th gen 2000-2001. So, even if the 4th gen produces the same power as the 5th gen, the 4th gen will be better off because of it's lighter mass. The 95-96 4th gens are the lightest.

I know they are the lightest. Thats why I was wondering if it is now possible to get the same hp as the 5th gens so then a 4th gen can woop it at the track.

 

No... 4th gens will never be able to whoop 5th gens at the track.
We are WAYYYY too cool to get whooped!!!

 

I thought VI actually reduced peak Hp? Not much, like 5hp-7hp. The first few dynos that were posted showed a loss of peak hp if I remember correctly. Not that I wouldn't give up 5hp at peak in order to pull to readline instead of falling on my face after 5.5k rpms.

 

Not only that, with a JWT ECU, you can go past redline. Thankfully it raises the redline as well to above 7000. That's almost like winding out a VTEC motor. The rev bands on those motors are huge.

No, the MEVI caused a loss of peak TORQUE, not horsepower. Horsepower remained about the same (+5), but the MEVI extends the powerband from 5600rpm pretty much all the way to redline so you can shift later.

Stock 4th Gen Torque vs 5th Gen:


The 4th Gen's get their peak torque from that big ol hump between 3-4k, and you can really feel it. The MEVI gets rid of this resonance hump and the torque curve becomes a lot smoother like in the 5th Gen's. But since you don't have that hump anymore, your peak torque goes down a little bit.

Now here is the power to weight ratio chart for the two cars.



As you can see, the two cars are pretty much dead even below 5500rpm, but the chart doesn't take into account the fact that 4th Gen's wheel sizes/weight are on average one size smaller than the 5th Gen's, so this would actually give 4th Gen's an advantage that is not illustrated here. What I should do is add some more dead weight to the 5th Gen's because of this, but I'm too lazy to bother figuring out what the difference in wheel weights are so that I know how much to add ;-)

Anyhow, with the MEVI, it'll extend the 4th Gen's peak power past 5500rpm where it steadily rolls off and allow it to keep building pretty much all the way to redline like the 5th Gen's.

So that will allow 4th Gen's to not only kick 5th Gen's a$$es around town, but on the highway as well. hehehe

 

i think i need to do a write up on sig reduction...

 

SteVTEC, you da man. Thanks for clearing that up for me.

 

Basically, w/o variable intake, I'll get smoked by 5th gen at high RPM...good write up steve.
