Well said. Forced induction is the only way to go in my opinion. Its abit more maintenance intensive but worth it. Guys spend big money on big cubic inch motors, big heads/cams and rarely exceed 600hp. They dont drive that well with huge cams and are very loud due to high compression. A simple smaller motor with some pressure and its running the same times.

Thirdgens are cheap and are good platforms to build on. One advantage you have over the guys with modern cars. If you have the pocketbook for it, go build the supra/vette/etc. Else buy a good platform and spend the money on the power plant.

My setup is pretty mild but certainly aint no sleeper. Its not exactly what I was planning it to be, but I'm happy with it. Soon as I get my cooling system problems squared away, it will be a very streetable car with 800+hp on tap. I hope to push this thing near 1000 if I can, or else I'll need to change heads/cam turbos.

Right now its a mild 650ish whp and runs 9's. Theres still import cars around me that i'd be hesitant on running. Thats kinda sad and exactly why my next build hopefully will be a 509-540 inch big block with twin 80's EVIL

How did I dodge anything!? your not making any sense! you said "does 15-psi on any given engine require x amount of fuel to compensate for it" are you saying that 15PSI on a 305 requires the same amount of fuel as a 454?!? Is X a constant!?

I wanna see some street vids of that thing. Ive seen the in car and the track vids...are there any more? I would love to see that IROC kill a vette on the street... or at least a boosted 300zx or something. Keep it up!!

Tricked, lets just settle this right now, because it bothers me to keep hijacking this thread. This is what I am saying, and you might be saying the same thing, and is the reason why I brought up tuning. When we tune a naturally aspirated engine, we first start off with a base, and this base is determined on the setup being used; cubic inch displacement, cylider head flow, cam specs, manifold and carb/EFI. The base is determined using math. However, being that every engine is different, we then fine tune the engine based on the velocity of the incoming air. With forced induction, we do the same exact thing, as we set up a base using the same method, but then include a base for boost using a set formula. Once the base is set, we then dial in the tune because of the varying efficiencies of the turbines. I am NOT saying that 15-psirequires the same fuel on a 305 than it does on a 454, the 454 will obviously need more. This is why I am asking you to read what I am saying. 15-psi is different when you compare engines, but 15-psi is 15-psi on a given engine. If your running a 454 against my 305, and both boost controllers are set to 15-psi, your engine is forcing a hell of a lot more air than mine is, but my engine IS still pushing 15-psi in it's own right. This is what I mean by 15-psi being 15-psi, I'm talking about ONE engine, I'm not making comparisons. The whole point of what I initially said was that TPI is not a restriction, because if the guage being used with it is reading 15-psi, then its forcing 15-psi for THAT engine....

Dallas is no better. I've had my *** handed to me a couple times in my 2005 GTO. Its stock but the fact that so many cars easily compete or beat a 400HP car is insane. 6 or 7 years ago I didn't see that nearly as often.

TxTtopZ

Oh yeah! Dallas has some nice cars! Texas in general is pretty fast but the thing I dont see is OLD muscle with tubs, blowers sticking out etc. If you look up some youtube vids of michigan (flint, detroit etc) you will see they stop traffic safely with blockers on the highway, then FROM A STOP go all out, which to me is the hardest of the hard core because you gotta show up dressed (slicks) with a dialed in suspension. On another note, Houston when I lived there did some dig racing on Rankin Rd. but 99.9% of the cars were on street tires of some sort.

100% correct but PSI IS NOT volume or a quantity of air. its just pressure from resistance, you can have 15psi and absolutley ZERO airflow. just because an engine makes 15psi on a boost gauge doesnt mean jack and absolutely not correlation with how much air the engine is actually consuming.... I get a kick outa the little import guys around here when we pull in with a turbo LS1 car and when they hear we run a max of 18lbs they laugh at us and say they run 30+ lbs and will destroy us lol

what im trying to get across is that you need to stop corellating pressure with air flow or how much air is getting into the engine and being used. Ive seen cars go from 20lbs to 25lbs and not pick up a single mph because of restrictions somewhere in the system. But by your earlier logic if you went from 15lbs to 25 lbs you are putting more air in the engine so making more power when in reality you may not be. Its all in how efficient an air pump your engine and turbo setup is. boost is just simply a measure of pressure/resistance.

I dont know anyone locally that can mess with texas cars. those guys are insane. I dont think ive ever seen sooo many 1000+ street cars in my life! and they came in all shapes and sizes, from hondas to a lexus to a ford GT and a turbo lambo!

I wish I had some. The days I did drive it on the street i couldnt find anything to play with I wasnt looking for cars tho, I was hunting for bikes. There are two 650-700awhp 4g63t cars I want to run with whenever I can get a chance. One talon and one evo. Evo went 10.8 at 142 on street tires in the heat and slow shifting. Should be a fun car.

The underground racing lambos are insane. The Ford GT's i hear are nuts too. Not to mention the supras which are fast EVERYWHERE all around the country. Everyone has a 1000whp+ car. Texas has the texas mile and that is going to bring the fast cars. I dont know any other states that have a track like that.

On LS1tech, Ohio Boys, Kentucky turbo, and few others build some NASTY turbo/blower cars.
Late model racecraft in texas however makes some sick cars too. Texas does have some great speed shops so some great cars

I see one of the underground lambos here and there, I think he lives close to my house. Black lambo gallardo with twin turbo's.. has "underground" written in gray letters on the bottom of the doors. Looks like it jumped off the screen while someone was playing Need For Speed. I bet it's got over a 1000hp. It also has methanol injection.

With stock turbo on my TTA (~530 cfm) HP increases incrementally as you raise boost from the stock 16.5#'s all the way up to 22#'s, but after that it is done and I've ran it as high as 26#'s. No other modifications slap on a TA61(900 cfm) 26#'s is the sweet spot and picked up 5 mph over the stocker at the same boost level. CFM and efficiencies dictate power levels, not necessarily boost PSI

So you say a 4 cyl getting 16 lbs is not as much as a 8 cyl getting 16lbs cuz the v8 is getting more cuz of the 4 more cylinders right?

I think your logic is little flawed. The lb of psi being pushed is measured before the air goes into the intake manifold. It's measure at the intake inlet. So follow me here.

4 cyl at the intake inlet measure 16lbs of psi.

a v8 also at the inlet measures 16lbs of psi.

They are getting the same amount of boost the difference is this.

the 4 cyl is getting air into only 4 cyls.
16 divided by 4 so each cylinder is only getting 4 lbs of boost.

the 8 cyl is only getting 16 divided by 8 = 2lbs per cylinder.
Of course this is just concept in real life flow is slightly different to each cyl but you get the point.

The same amount of boost is the same amount of boost on any engine. In a perfect world where a 4 cyl naturally made the same horse and tq as a v8 with the same curve (never will happen) then you gave both engines the same amount of boost they would make the same amount of power.

But in the real world more cubes mean more air which means more power so you see a 4 cyl boosting 20 lbs to keep up with a v8 only boosting 8lbs.

The smaller cubed engine always play catch up. And the benifit is the v if built can handle more boost then a 4 for the simple reason that it's sharing the lbs between 8 cylinder so what 4cyl pushing 20lbs is to a v8 smillar to pushing 10lbs in that same 4cyl.

I hope I explained that on here like I did in my head...lol

Tricked, you were taking what I was saying completely out of context, and I never correlated such a thing. For example, my buddy Bob just picked up TTA number 850 from a guy named Steve on this board about two weeks ago. The stock turbo, although technically can see up to 30-psi of boost, is already done way before that. It only hinder's power at that boost pressure level because of the heat being associated with it. Again, it can reach that boost level, but its actually doing more harm than good because of rising air temps, and the inefficiency of the smaller turbo being able to keep up with engine demand. Nobody is arguing that, and I never said that power is made at all boost levels, I only said that a particular psi is being reached, whether power is made or not is based on quite a few variables. Alky injection does help to rememdy such problems that smaller turbo's have at higher boost levels....

Again, you took what I said out of context, and I never said that as boost increases that power automatically increases with it. The only thing that I said was that TPI is not a restriction, that 15-psi is obviously doable, and that if the gauge embellishes 15-psi of boost, then that is how much pressure is being made. That is all that was said, and you immediately jumped on that and somehow implied that I was comparing two totally different engines at the same boost pressure level somehow making the same power, when I never said that. Nor did I ever say that just because 15-psi is being realized, that all of that pressure was being utilized. This is why I kept telling you to reread what I was saying. If what I said somehow implied whatever you feel that I was implying, I honestly can't help that, but that is obviously not what I was saying....

No, what he is saying is that it takes more air to create the same boost pressure because of the larger cubic inch displacement. Think of it in terms of vacuum. If a 305 is idling at 18" of vacuum, and a 454 is idling at 18" of vacuum, do you seriously think that both engines are measuring the same amount of air at that reading? The 454 is obviously taking in more air at idle. Although vacuum is reading the same, the quantity of the air is different. It is the same with boost, if a 305 is measuring 15-psi of boost, along with the 454 measuring 15-psi of boost, the 454 is obviously taking in more air because of the larger cubic inch displacement....

It is being measured before the combustion chamber, but remember that the intake tract is depicting the flow. Simply open up the intake tract and boost pressure will decrease, obstruct the intake tract and boost pressure will rise. This was what I was getting at, it can easily be understood just by blowing into a straw. It is impossible to simply say that power is being made at any given boost pressure without going through all of the variables first....

Only for THAT particular engine though. The only time 15-psi truly equals 15-psi with two seperate engines is when both engines are identical in every single way....

A stock turbo is in fact done once you exceed around 25 pounds of boost with a bone stock setup, but it can still make decent power when you start changing things to lower air temps. Did you at least up your injectors at that higher psi because the stock 28 pounders max out their duty cycle at that level? Are you running a turbo tweak chip? Are you running a Razor alky kit? MAF Translator? These are the variables that I am talking about. Ed Brewer holds the record for a bone stock TTA running alky injection, and I believe he ran an 11.23. In your case, you may not be making power at those boost levels with a stock turbo, but Ed Brewer did with the addition of alky, and its the variables that always make the difference....

1BADDAM

That wasn't the point of the post, I was agreeing with Tricked-Out-Toy, about the fact that when you increase boost pressure you don't necessarily increase power.

Anyway, if your talking about Ed Brewer he ran that in a Turbo T, not a TTA. Also, the car is not "bone stock". He ran 11.37 @ 116.35 on the stock turbo with supporting mods. I ran 113.5 mph on multiple occasions back in 02' with the stock turbo, stock fuel pump, and stock injectors without the benefit of alky and 8 years of chip technology.

those people arguing about boost completely hijacked this thread....back on topic.
my first third gen was a v6 and on the street not many people wanted to race me, it was pretty easy to tell it wasn't a v8 so people left me alone. however, at school that was a different story, it was sad considering that everyone there owns little four cylinders that i couldn't even touch in my car, and i couldn't even compare to v6s just a few yrs newer. that's all different now though, sold the old one and got another 3rd gen, and this time its something with a little bit of power behind it

the fact is that our cars are aging quickly compared to the latest and greatest cars coming out today, look at the new v6 camaro, over 300 horsepower! and the best our l98s had to offer stock was 245? its going to take heavy modding for all of us to still be taking out new cars...in general
