What's the best way to achieve 50hp?

Nismoracer · 06-05-2011, 10:08 PM

Would like the nismo to be at 400hp. What's the best way to do it?

Gtm supercharger.

Supercharger or TT

400 at the crank or the wheels? If it's the crank, exhaust and intake should get you there. If it's at the wheels, you're looking at forced induction.

NOS: I'm looking at 100 or 150 shot with a digital controller, 1% at 3500 and 100% at 7000. That way it should not overpower the tires too bad.

Just engine hp. 350hp as advertised would like to be around 400hp. Thinking intake and full exhaust would do it. Just don't want it to sound like a loud fart can with rasp. May just get some hfc. Already replaced the muffler but I don't think that will make it 50hp. Prob have to go headers and all the way back.

Doit! Report back!

A supercharger will do the 400whp. I'm think about one for my own nismo Z.

Intake and exhaust alone will not net you 50 whp.

A Good driving school on the other hand will net you more than 50whp on the track

This is correct. I think it was established on another thread that there is a 15% loss from Base HP to Wheel HP. You can get close to 400 HP but i dont think you're going to be over it...

~17%, based on SAE corrected dynojet values.

Unexpectedly, same for AT and MT, BTW.

FI or nitrous. Bolt-ons alone aren't quite going to get you there.

Oh sure they will. Pistons, Cams, heads, headers, intake, exhaust and tune will get you there with hp to spare. It's all matter of how much you want to spend. Forced induction isn't the only way to get over 400 hp. You don't need nitrous or forced induction.

I always find these discussions funny. Much of the discussion is focused on peak HP with a few people who get it. What is primary use of the car?

If it's a street car you should be more concerned about maximizing mid range torque and hp over stock baseline. Too many people focus on peak number due to lack of understanding what makes a fast car for each application. If you can't make a redline shift every time 50 peak hp at top of rev limit isn't going to help if you lose critical mid range power.

Having said that a proven good set of intakes that don't hurt torque numbers, long tube headers, Uprev tune should get you 20 to 25 hp/ torque that is usable from mid range to top end. The stated hP claims for all bolt ons are wildly exaggerated and tend to be focused on peak hp. Most use a poor stock dyno run and then put up a good run with bolt on to make hp claims. many don't tell you type of dyno or if it's a properly corrected number. Dyno claims are like weight loss pill commercial claims in my opinion. Lots of wild claims with few facts or data often.

Realistically only way you're going to gain 50 usable hp in a street car is to go forced induction. A few bolt ons will not likely get anywhere close to more 50 HP on a Nismo.

I'd love to see someone do a large displacement motor build. I think bigger displacement VQ would grab 50 plus hp easily. Something like 4.5 liter, aggressive cams and heads, etc but that goes beyond simple bolt on.

With my nismo I have focused more on getting weight off the car especially rotating weight. Aluminum hat rotors, lightweight flywheel, and lightweight 18 inch wheels are best bolt ons in my opinion.
