Got that covered in a different project, and heavily covered.

This N/A/nitrous car is basically a daily driver fun car, not doing it to be the best highway killer, but it'll still be in the "manslaughter" category.

wow, I'm jealous.. I think I have seen every video NRE has on their site. The keyboard didn't like all the drool.

Ok, got my advanced reading in for today, great stuff guys.. I'll just mosey back over to the internal/external/midwest areas and keep dreaming for now

The only engine he doesn't have a video for is his 454 TT.....1,850 FWHP, very mild cammed built for street use Intake sprays pump gas up to 900 HP, than 8 other stand-by injectors kick on automatically and spray race gas all the way up to 1,850 HP. Best of both worlds.

Titanium valvetrain is the key Valves,retiners,locks ect..

Allso pretty good lifters

Try to get some Nascar Ti valves ect. on ebay,I got mine for 200$ in/ex valves, those cost about 2500$ new and cut them to your specs

The only thing nitrous directly affects is your torque.

HP = TQ x RPM / 5252

So to over-simplify things, let's say you have a 200 shot of nitrous and it boosts your torque by approximately 200 lb/ft throughout the rpm range (hey, I said simple). If your RPM range were 5000-6000 RPM's, then it is adding around 190-230 HP or so. If your RPM range were 7000-8000, then it is adding around 265-305 HP or so.

It's more complicated than that, but it gives you a really general idea of how nitrous likes RPM's.

I think thas the motor they were dynoing while I was there last wk.

Yeah, but that's not just nitrous, its pretty much every performance engine part.

If you're building a highway car to run up to 180 why not just swap in an M6 and a set of 3.42s. I think 5th runs up to around 180 stock.

Here's a calculator to help you figure out what you want.

If your buildling a roll racer, lose the auto unless you get to pick the starting speed all the time. I also agree that the valvetrain is where I would be concerned for spinning 7500+, one other thing to think about would be a longer rod. A longer rod lowers side loading, piston speed, moves the piston past TDC slower, and it will allow the valve to open farther during peak flow.

That still doesn't explain how nitrous is different than say, a blower or turbo. Both a blower and turbo only add torque as well, thus increasing horsepower. If you mean that nitrous doesn't shift your useable rpm range, then that makes more sense, but the things responsible for powerband location are things like what the heads flow, cam specs, intake design.

the diff in nitrous is that it introduces that much air/fuel (or power, depending on how you want to think of it) at EVERY RPM.
its constant.

since horsepower is calculated based upon RPM, it looks weird.

meanwhile with a turbo or supercharger, you flow less air at less RPMs... its variable.


even if you had a magic turbo that slammed just as much air into the intake at low RPM that it does at high RPM... its still dependant somewhat on the efficiency of the engine to get it in there. nitrous is not dependant upon that.

At 180 on the street, you'll likely be the victim.
You won't need to worry about engine reliability, the engine will outlive you..

RussStang

Yeah, I understand all of that. I was just trying to keep it simple, because in the end, both types of power adders still "only produce torque". That still doesn't clear up the Louie's description of how nitrous works to me. I know how nitrous works. A lid and a catback still "only produce torque" as well.

This thread is ridiculous... you want to build a "daily driver" ls1 that revs to 9k? And it's a highway roll racer... with an automatic.

MrDude_1

iTrader: (4)

yea.. i know...


but it would be hypocritical of me to say anything.

i drive a 3rdgen camaro convertible as a drag/driver car...
and im working on making a S10 into a autocross/driver/parts hauler.

Quickin

I agree, 180 on a "street" is ridiculous. There's these cool things out there called highways.

Damn, I was hoping to get through a whole thread without the nay-sayers. You might want to hang out in south Florida and watch some roll races. 180 is typical for years and years...never once has someone had an accident. And a bunch of cars and bikes also like to go over 200. I've maxed my car out probably 50 times since I've had it (8 1/2 years) and it rides perfectly at those speeds (175-ish or better). Only unsafe assclowns who make stupid decisions whipe out.

Quickin

No, I was just wondering what it would take to build that type of engine, as the thread title says. If its not needed to get the desired results than why bother.

Quickin

You just need to get out more. There all over the place down here. You can only learn so much hanging out on internet forums.

NRE is just one of those builders that build just that type pf car. Minus the parts hauler.

Quickin, come on please tell us just how much the 454is going to set you back....please

i know the 427's run at about 35k starting!

thanks chris.
