Nitrous Shot Limited To? - Honda Prelude Forum

Toretto · 06-28-2003, 05:38 PM

I am having the money loaned to me inorder to have my car completely overhauled. Which includes building the engine for lots of nitrous. My question is, when I upgrade my dry kit to a DP one, whats the highest shot I can spray? I was told 175 shot due to the nitrous line size that I got with the dry kit. Anyone know?

NXLude · 06-28-2003, 06:32 PM

In general a small displacement 4 banger can make around 425 or so hp before maximum volume is achieved and you cant fit any more nitrous in. The few ludes ive seen run 125 shot were all running mid-12s. I would see little reason to run more than 125 shot, despite the fact you could probably push a 200 or 225 through it.....On a seperate note, are you buying a DP conversion kit or just piecing it together? I wanna do the same. Also, what compression are you running?

If I remember correctly form SCC high 11's are the best you can get with a fully built motor and nitrous. They were refering to our motor in a hatch so mid 12's would make sense because of the weight. These times assume slicks. Don't get into to much debt making the fastest prelude, they just are not good drag cars.

Toretto · 06-28-2003, 07:34 PM

By time I am all done, I will probably have about 15k into the car. Thats engine and cosmetics. I would assume those Ludes that ran mid 12's on a 125 shot had slicks. I am gonna stick with 10:1 compression. I dont think raising the compression would justify the extra tuning needed. I am tired of hearing that the Prelude is not a drag racing car. I can take my moms Civic EX and drag race it. Is it gonna be the fastest, probably not, but I bet there wont be very many cars on the street that can keep up, let alone other FWD cars.

I am buying the DP conversion kit from NOS.

red98lude · 06-28-2003, 07:49 PM

Don't get pissy, I just don't want you to spend alot of money and be dissapointed. The fastest 5th gen I have even seen had a fully built motor, 150 shot DP, and slicks. He ran a 12.5. If you want to go all out, do it, in street trim I don't think you can break low 13's, which is still fast for a FWD car.

nuro · 06-28-2003, 09:52 PM

why was that lude with the 125 shot running mid 12's? slicks and stripped interior? that seems awfully quick. i dont see the FI boys runnin mid-12s....

alphajesse · 06-29-2003, 12:54 AM

That was in an issue of honda-tuning I think. The car looked to have a full interior...
NXlude, the h22 is not a small-displacement 4-banger.
red98lude... a lude has much better aerodynamics than a hatchback.with 125+ shot, 12's are reasonable, and with more n2o, even faster!

all 5th gens, all with less than 100hp shots. High 13's low 14's
ALL ON STREET TIRES! 11's are realistic with 125+ w/ slicks.

Toretto · 06-29-2003, 10:07 AM

I agree, slicks and a limited slip differential are gonna keep the traction problems to a minimum. If people are doing 13's with a 75 shot and street tires, they would probably run low 13's with slicks. I dont belive you need a built motor to get 12's, 100shot DP, tuned on a dyno, and slicks would probably result in high 12's. Lets look to break 12's before we even think about going after the 11's.

nuro · 06-29-2003, 11:32 AM

i also believe 12's are possible. (high 12s) with good tires, LSD, and a correctly tuned/built motor with about a 120 shot. here's what i dont get tho... 120shot = 120whp. lets say a NA build up is done and gets 220whp (possible, but really good too). so that makes 340whp. plus u cant shoot that off the line. now i ask again, why arent the FI boys getting in 12s with this much power? or are there simply no fi people with that much power on here in a street trim lude 4th or 5th gen?

I know its a big 4, but an engine is not restricted by the displacement, its affected by the inline 4 design.....

FI guys have the same problem as us with traction in 1st gear with so much power, so like us, their first gear is useless. Also, turbo lag is put into effect with the turbo guys. They don't get the instant burst of power nitrous guys get. Their power has to build up. Same thing with the JRSC guys. All dependent on the boost building up.

Also, the fact that there aren't many 340 whp preludes out there. The highest I think I have seen is 285 whp or sumthin of that liking. I know some h23s are making some mad hp, but not in the 300+ range I dun think.

Toretto · 07-06-2003, 10:54 AM

Tuning issues are a much bigger problem with Turbo systems. Turbo systems that make alot of power, usually make alot of peak power. If I spray 150 shot, I have an extra HP as soon as I spray. Turbo usually starts building big power at about 4500+ rpms. Of course you could go with a lag free small ass turbo, but then your never gonna make big HP. For those who really only want to be hella fast for the track, nitrous is the way to go. I ran better times with a short ram intake and a 60shot, than a V6 mustang did with a supercharger running 6psi. H22a makes power.

NXLude · 07-06-2003, 04:22 PM

To make a 125 shot worth your while you will need 2 stages or a controller.....way too much power off the line.......

Toretto · 07-07-2003, 08:43 PM

Even with slicks, I dont know if 125-150 shot would get traction. I am most likely going to invest in a controller, and try to find out what solenoids can best hold up to the abuse.

NXLude · 07-07-2003, 10:34 PM

controller is best way....NX will swear up and down that their big fat solenoids are built with that controller in mind....that is a big reason why the make em so beefy

Toretto · 07-08-2003, 04:08 PM

Do you know if I can use NX noids with my NOS nitrous kit? Also, any word on beefy NOS noids that can take the abuse?

alphajesse · 07-08-2003, 04:50 PM

Noids are noids, as long as the fittings are the same size (probably are) you're set to go!

NXLude · 07-08-2003, 05:14 PM

Noids are not noids....like anyother part on a car some are crap some arent....NOS does have noids that are big enough to handle, they just arent in the normal NOS kit.....i think the kit comes with cheater noids and the bigger one is powershot noids....I cant remember.....youll have no prob with NX on you NOS kit....alot of guys end up switching to NX anyhoo so I know they work...
