What would it take to get a 4th gen to push 200 HP at the wheels? NA preferably...

pawn

well.....your only about 10hp shy of that 200 mark.....so....a y-pipe would definetly get you their!!!

the carparts.com HP/dyno thingy....you have around 162/184 at the wheels, so I guess the usual mods and maybe some nitrous will have you well over 200. just a guess though

pawn

I thought that are cars had 190hp so then nitrous would put you way over the 200fwhp mark....A simple y-pipe should easily put him over the 200fwhp mark....

4th gens push 190HP at the crank, more like 150-160 at the wheels.

My bad...I was going off of the thread title 200fwhp? i didn't even notice that he asked "What would it take to get a 4th gen to push 200 HP at the wheels? NA preferably..."

drivetrain power loss through the transmission that 190 "simmers" down to around 150-160ish. I don't have a fourth gen but I'm guessing the usual bolt-ons and stuff would put him around 180-190 at wheel HP depending on trans type I guess. after that slap on a 40 or 50 shot and you're set!

*smacks himself in the face* Oh $hit...boy is my face red....i wasn't really even payin attention when i was reading this thread...for some reason i was thinking Fwhp=Fly Wheel Horse power.....im an idiot....sorry for all the confusion....

guido_sst

No biggie, just looking for ideas.

You gotta mod yourself out the ***..

UDP, b-pipe, y-pipe, muffler, intake, straight-pipe instead of cat.. I think that'd put you close (ie, within 15) with a little luck. You might have to go a little farther than bolt ons to do it though, ie, NOS. If it's a 95-96, an ECU could push you there with those bolt ons and tuned right I think.

I don't know of many 4th gen 5 speeds that have even come close to 190 fwhp to the wheels NA....even Jeff K's infamous 14.3 second Max only made 185fwhp. It's gonna be even harder get that kinda power out of an auto. Your car put down 155fwhp/175fwtq stock so that means you need to get an increase of 45fwhp. That's not gonna happen unless you either add artifical induction OR find a way to get the motor to continue to breath after 5600 rpms.

lookin at your sig...are you a maxima killer,you went through 2 already ,hope 3rd is a charm

guido_sst

First one had a slight run in with a guardrail at 65. After I got out of the hospital, bought the second, which was hit by a POS Pontiac Aztek. Working on #3 now, hopefully it'll stick around a bit longer.

hey by the looks of the pattern...if you reck this one at least you'll have a 97'.....

Even with an ECU, CAI, UDP, Y-pipe, hi-flow cat, mid-pipe and exhaust; no one has made 200 fwhp in a Max NA. 5th gens have a much higher flowing Y-pipe and exhaust than 4th gens from the factory and don't get the same gains from bolt-ons. There are only 2 maximas to my knowledge that have hit 200 fwhp NA. The first is Stillen's 97' PPG Pace Car. It has an intake, prototype Y-pipe, exhaust, ECU, extrude honed intake, extrude honed exhaust manifolds, ported and milled heads and custom reground cams. The other is a road racer in Canada who has a 5th gen with bolt-ons, porting and a set of prototype Wolf re-ground cams.

To get there you will either have to look at very expensive engine work, a set of $3000 JWT cam regrinds or wait for the 02' Max which should do it from the factory. By comparison, the Supercharger will do about 232 fwhp on a 4th gen and 245 fwhp on a 5th without any other mods.

Ironlord

So you're saying that a 5th gen stick, which dyno's usually around 180-190 fwhp stock, couldn't get 200 fwhp NA? That between CAI, UDP, ypipe, full catback, ECU, and other bolt on mods they couldn't gain that additional 10-20 fwhp they needed? I understand that it might be difficult and rare, but not limited to only 2 cars...

Dave B

MadMax has already hit over 200fwhp with his 2000 SE with a y-pipe and CAI

I am pretty sure Jeff's car dynoed at 193.6 HP to the wheels, I may be a tenth or to off. I wish I got the chance to dyno my 95 max when I had- Y-Pipe,intake,Y-Pipe,RT cat,Cat-back,G-Force ECU,alluminum flywheel, I was had a UDP too but never installed it. Still today this day I think I was making over 200 FWHP, to bad I never proved it. I am still tempted to reach my goal of 200 FWHP on my 95 max but I think my soon to be 2002 Altima will be able to do that stock with out all the headaches.

Dave B

I thought I remembered Jeff putting down 187fwhp and about 204fwtq. A couple things must be considered here. First point is that dynos all read a little differently. A Dynojet 248 can have up to 5% difference between machines which could very significant. This is why it is critical to use the same dyno everytime. A 5% difference could mean up to 5-9fwhp and torque on a NA Maxima. After studying Jeff's timeslips religously , I've noticed that his car is really no faster than mine even though technically he has over 10hp and tq than my Maxima. He was definately quicker, but his 60 foots were better than mine, he was running slightly below sea level were as I'm at 1100', and on drag radials.

Second point is that getting 200fwhp is near impossible out of a NA 4th gen VQ because the intake manifold severely restricts power past 5800rpms. There is no real way to substainally increase air flow to the NA 4th gen VQ after you've done an intake and exhaust. Hp is directly related to engine rpm. As the engine rpms rise, hp increases. The longer you're engine can breath, the more hp you make. With intake and exhaust more power is made past 5800, BUT the power still falls off, just not as dramatically. The only way to continue to make the power climb after 5800 is to force feed it air with a blower. The reason the 5th gen VQ breathes after 5800 is because of the varible runner intake manifold. If we could swap this onto a 4th gen, the car would absolutely scream for NA rivaling the 2002 260hp Maxima.

I agree with the person that said add the Y-pipe

DaEnigma

I agree with Dave on the intake manifold. Has anyone got the status on the intake manifold swap?
