As a nitrous junky, let me just clear something up. My nitrous setup is just about as "Max Effort" as you can get with a nitrous car. I keep seeing the words (nitrous and cheap) in the same sentence. Let me tell you, building a "Max Effort" nitrous car is NOT cheap. It may not be as expensive as a FI setup, but to sum it up there; is nothing cheap at all when it comes to going fast (and I'm not talking about running 10's ).

Do I care about drivability-no, do I care about A/C- no, and I could give a rats *** about emissions.

One of the reasons I didn't build a forced induction car (and I have entertained that idea) is because there was nothing proven in the LS1 community when I made my decision. Now that we have Harlan, Mightmouse, and Raymer who did all the back work and R&D, I'm seriously considering a Turbo build up next year. Until then, you'll see my nitrous booty in the 8's............................................... ......

 

I agree with Mike on that one.

I watched DERTY put his DP system together on my kitchen table. I think he had more fittings there than I have in my car. And I got ALOT

 

Pretty good thread. It seems that the main reason alot of big power fi cars aren't the quickest on the track is because a majority of them are mainly street cars with full interior, ect. And they are all pretty impressive. However, I do wonder how many of these 600rwhp streetcars can actually hook up the power on the street? I would imagine not many (if you can please tell your suspension setup). I almost went with the qmp turbo instead of a 427 (still waiting after 6 months dammit). Why? Let's be realistic, it would have been cool to brag to people and show them a dyno graph, and would sound cool while driving. Tell me that is not a big reason some of you street guys went fi lol. And that is cool. But what would have sucked for me would have been blowing up the rear tires everytime I floored it. And it would have been embarrassing to lose to a 400hp stang because he could hook up and I couldn't. Seen it many times. So, TO ME, having that much power all the time would have been no use to me. I care about winning a race more than bragging about my set up. Kinda ironic because I know I will have trouble hooking with 500/500+ anyway, but I think with ET Streets is could be doable. Plus, I will have something in the rear hatch for the strip and the few occasions I come across a 700rwhp car on the highway hehe. No offense to you fi peeps, that is just me. Yall do have some badass cars. Rock on!

 

All- a couple of you have hit it on the head... for a given level of performance (say, an 11.0), generally speaking, the force fed car is going to be more refined.

Take, for example, a Magnacharged Z06. I have seen an otherwise stock '03 Z06 with just the Magnacharger (the older, non-intercooled one) and a set of headers make ~450 RWHP (through the stock cat-back, no less). RWTQ was somewhere in the same neighborhood at ~440, IIRC. In any event, we all know that those numbers are certainly achievable with a heads/cam setup, or even a (relatively) mild shot. However, the Magnacharged Z06 always has the power on tap (as the nitroused car wouldn't) and starts, idles, and drives like a bone stock car (as the H/C car wouldn't).

That being said, are there quicker cars out there for the money?? Sure there are... but how many of them will start on the first crank, idle like a rock, and allow you to place your order at a drive through without turning the car off while always having well over 400 at the wheels every time you drop the hammer??

I think it's all about the sacrafices you're willing to make...

 

well, I like nitrous for street racing, which is what i do. I have a 382 2000 Camaro that is very mild and runs mid 11's on radials, 3.23 gears, and automatic with 2800 stall. Full weight witha 417 lb. driver! I added some stuff including a Rossler 4l60E, Vig 3400 multidisc stall and biger fuel system, and am now installing my GM MAF kit with 200 hp single stage shot. When done, it goes to Detroit for tuning. I would expect mid to low 10's on the drag radials on botle and hopelfully lower 11's on motor. I am not worried about any FI cars around here...but that is my area, and I know there are fast FI cars out there, just not around here. Actually, there is a LPE vette with about 650 rwhp on race gas (auto, stg 1+ boost controllerm built bottom end, etc.). He usually runs stock radials, so he doesnt hook!

I like turbo, but soooooooo much lag...a supra here has 744 rwhp and he LOVES his dyno graphs. He wont race me from a dead stop (me with my old non-nitrous set up and radials, and him on ET Streete), only wants to go from a 70 mph kick. His lag is huge and he cant launch...i think he ran mid to high 11's on ET streets, race gas, etc....so basically he has 300 rwhp more than me and runs the same or slower.

I have all the amnenities, fairly quiet car (stock rear SS exhaust with cutout), idles and drives like stock, mild converter, etc. I have les than 27,000 TOTAL in my car counting buying the car (used with the MTI 382 allready done). Nitrous was the best/cheapest for me for what i wnat to do. I doubt it will run faster with a turbo setup (at least on pump gas) than with the 200 shot and some fuel additive. But the most iportant thing for me is not to make excuses....such as I hear form people all the time. When I beat the procharged and ATI cars around here, they talk about how they have stock engines and mine is built....must hav eforgot about their blowers! I don't want to loose on the street to another street car around here, that is my goal. Full race cars don't count, but if someone has a nasty turbo that can pull mr from a 50-140 kick I would be impressed and may think about a turbo then (and drop the nitrous to 50-100 shot). I hope we see more good results with turbo, but the problem always has been dyno numbers and not great track times especially in a mild street car. I hope that changes with the newer systems we have oming out now.

 

Scott's car weighed 3700lbs and went 10.3@133, he was shortshifting it too........ He was making 600rwhp with the ATI procharger setup.......

My car weighs 3600lbs with me in it.........I want to get it down lower, but I'm at the point to where its going to cost $ to get lighter parts.......I hope for over 600rwhp, 650 would be nice for now........

I'm just hoping my 28x12.5x15 ET street will hold of a boosted trans-brake.....

 

One of the guys over the Corvetteforum.com just laid down 720rwhp with a D1 and 346cid(12psi). He is still looking for some more injector....

My three cents:

1) FI kits, like supercharger kits, came out about two years after the LS1 F-Bodies hit the scene (1999 vs 1997).

2) FI kits are more dependent on good tuning so folks typically suffered by not having enough injector or a way to take out timing unless they used Ed Wright or Steve Cole for the early years of the FI scene.

3) FI kits have a higher initial price so many folks elected to get nitrous kits and then add to them.

4) FI scene really started to blossom towards the end of 2002... LS1 Edit was available to all, some folks started to run FAST systems.

There are more reasons why FI lagged behind nitrous, but the fact there are more nitrous setups out there accelerated because folks who were looking at FI didn't even try it since they could not find people to emulate.

Even my year old setup of a big blower on a stock cube engine is somewhat daring, nobody had a stock cube LS1 making more than 700rwhp with a blower until we did my car.

 

Nitrous (especially wet) is also WAY easier to setup and tune. You get around the factory MAF issues and as long as your fuel system (pump and lines) are adequate you can make big numbers

Cost is the other factor. It is a fraction of the cost to add 200 RWHP to a nitrous car versus a FI car.

 

Dyno numbers are nice, but they only show what the car is capable of. I've seen many a 600hp car knock out an amazing 11-second pass. Also, V8s don't have much of a lag problem because we have something the Supras don't...cubic inches. Our motors pump more air which will spin the turbo(s) faster.

 

On the Street, ill take blower over NOS anytime. Its always there, and It seems the big NOS systems wont hook on the street as good as my car. But unfortunately at the track its a different story.

 

I didn't read ALL pages, but to the orginal poster, you must be crazy. They let turbos in Mustang racing and they totally dominated, so much so, they started put tons of restrictions on them so the nitrous cars could keep up..lol. Turbos can not be beat when done properly. That is why you have Mustangs with small blocks/turbos OUTRUNNING 632ci 3 fogger havin' Chevys.

So ,why in the LS1 world are they not faster? They have not gone to right person to have an LS1 built. If I were building any kind of serious turbo setup, it would be done at a Mustang shop. Those guys know how to get it done. There are so many variables in a turbo car. Your Yank converter isn't going to cut it, you need something that can handle ALL the torque. You need a Glide, not the TH400 junk, a badass boost controller...not your store bought one either Just these 3 things are the tip of the ice-berg, but I have yet to see an LS1 with these parts, let alone all the others!

For the time being, enjoy your nitrous wins, they are short lived. It used to be that way when Mustang racing was in it infancy.

 

As far as nawwws on the street, that is why I am going to run a progressive controller. And it will be only on the highway. I won't be spraying out of the hole at a red light lol. You say your car hooks. What suspension are you running? That would be great info to me if you really can hook it up.

 

Forget the glide...what LS1's need is a Lenko.

 

Beg to differ. There are several qualified shops that can handle tuning a turbo'd or supercharged LS1 and make "serious" power. And I can't think of one Mustang shop that would know the first thing about the in's and out's of the LS1 engine, much less the PCM tuning on it. Trust me, just because stuff works on a Mustang, doesn't mean it will work on an LS1. After all, today's 5.0 Mustang motor has been around since when...early 80's?? So like 25 years basically. And the LS1 how long?? 5 years. Heck, there aren't even aftermarket heads available for it yet! We (collectively speaking here) can make 900+HP with stock cranks and blocks! (in some cases, even stock engines with single power adders!!) Show me a Mustang that's doing that.

Why won't the Yank converter work? Why won't it handle all the torque?? My Z had a Yank converter in it and went 9's at more than full weight.
And I really don't think you'd want to run a Glide in a nearly 4000lb car either. Just ask people like Coan, Chance, Extreme, etc. My 400Turbo never missed a beat, FWIW.

 

with project formulation what kind of time are you expecting to see with that "stock" motor, i would like to see how it ran with the 7psi and the 500+rwhp. by the way love the kit and good luck with it

 

Kinda what I was thinking. Sure the 400 pulls a lot of power, but it'll hold up to just about anything you can throw at it with either of the late-model blocks (LT1/LS1).

 

I agree, n2o cars are faster. but hey lets race 10 times in a row, no getting out of the car or doing anything. have to stay buckled in all 10 races, hot lapped.
lets go. How bout a street race, oh your bottle is empty because you had to work late so the speed shop was closed, sure i'll be back tommorow to race you once the bottle is full.
Your right, n2o cars are faster and easier to do and cheeper, so why even ask the question. get juiced!!!! easy as that.

 

If memory serves me correctly the FASTEST and QUICKEST Pro 5.0 mustang last year was a supercharged car.

 

Wasn't it boosted and sprayed?
