MORE HORSEPOWER!!!

[IvoryJ30t]

motec seems to be the only standalone that fits the bill for the VH.

every other system wants to convert to waste spark, which is a waste.

with the motec, you can send descrete [8 channel] signals to an AEM 8 channel cdi ignition firing the stock coils. or, if heat is a concern, you can mount 4 coils on each strut tower, and short leads to the plugs.

no sense in wasting 50% of the spark energy on a non-firing cylinder.

Check this out!

Damn that's nice. I like this statement:"Donnie personally drove the car to be certain his client is getting the performance he is paying for. The results speak for themselves!"

[1992Q45A]

The BAD Q was put together way before AGMs Q

Everyone loves to hate on the BAD Q.

Cracks me up

Also cracks me up how nobody thinks Thomas knight couldnt have an eaton 112 with a custom manifold delivered to your house in very short time

Blah

If i had a shop like that guy got his benz fixed up id drop the money right now

[PoorManQ45]

You see how the supercharger is the upper intake manifold on that MB.

Could something like that be disigned for the Q45? That would get rid of any of the space limitations, correct?

[DAEDALUS]

If i had a shop like that guy got his benz fixed up id drop the money right now

Wasn't Mr. Knight offering a package at around $5k? It's not a group buy price, but it is available, is it not? I'm sure that's cheaper than the Kleemann upgrade.

[1992Q45A]

Daed,

Yea, I organized it

He designed the B.A.D. car with an eaton m90. He told me he now wants to use a 112, which would provide more down low power.. 112 is what they use on the XJR

It's less then 5k as well

Problem is I need a good shop that would give my car the proper treatment. I'm not a mechanic, and I don't want to have 6 months in downtime.

I need professionals like that shop seems to be

If you want some serious power from your Q45, you need to go with Forced Induction.

You can either go with a turbo or a supercharger.

As far as I know, no one sells a turbo kit for the Q.

Now, we know that there is a supercharger kit available for our cars.

So, how come no one is interested in it ?

-sijoko

[911/Q45]

No one is interested because:#1- The cost of the kit equals the total value of the car, one wreck and you are out the $.#2- The cooling, lubrication, trans, brakes and suspension systems for the Q are not up to the increased power. Modding these to standard would triple the total cost.#3- 95% of the Qs out there need $5 to $10K of repair just to bring them up to stock condition and are owned by guys that can't afford to do that.

He's right. That being said creating a two luxury cruiser with serious power would be worth the investment. I think the active suspension would be up to the challenge, easily. Normal suspension, do the upgrades available, and see how it comes out. Brakes and transmission should be upgraded, but not totally required

I think creating an M5 type car would be awesome. Automobile mag said my car (which just had standard mods) was the 500Es rival, and in the handling department, was better. This just shows you our cars could be upgraded and be brought to modern standards, or close to it.

I am more then willing to order the kit from Thomas and go with JWT for ECU mapping, but I don't know of a shop that knows the Q in and out, and just by judging the effort Rob had to put in his car for a set of headers, means the labor would be enormous for a boosted VH.

I think the car is up to the challenge, I would just like a shop like that in the benz article, for our cars

[Rex Rich]

I put this post MORE HORSEPOWER!!! up to get an idea as to who the people are on this forum.Its turned out better than I could ever imagine! A lot of you are F*n smart about this stuff and your cars!

We take our Qs seriously! They are worth it, now all we need is the F*n $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

We really need one of us to do the mod even if its just the engine/stocker and then do a write-up. That would really be big hit, this forum would go down in history!

We are lucky to be here! Support Nico

Thx a lot

[sijoko]

I think that in another 5 years, the only 90-96 Q45 you will see on the roads will be owned by enthusiasts.

The Q is a car that should be modified. The engine is overbuilt, the suspension can easily be modified, the trans can be built to racing specs.

The only thing needed is owner enthusiasm.

That being said, I plan on building a Homebrew turbo kit for my car before spring.

[psychic_mechanic]

Am I the only one that thinks Rex Rich and Poor Man's Q are posting from the same computer?

After I get back from Japan in a couple years, Id love to do a 90-93 project car. Get one with a ratty interior and chain guide failure for pocket change and turn it into a beast. It would be so much easier in the long run to swap in an engine with aftermarket support though.

I'd love to run one through the Grassroots Motorsports Challenge, where you have a $2000 budget to work with. A Q wouldn't come close to winning, but it would be different.

[pito11213]

psychic you are probably not the only one to think that just the only one that noticed enough to post on it.

The Q supercharged would be a nice ride. 400 HP is more than enough for street use. Hell the way it is now is just fine.

[PoorManQ45]

Am I the only one that thinks Rex Rich and Poor Man's Q are posting from the same computer?

I'm bi-poler. That's it.

No, we are not the same person. As you guys have probably noticed, I am only 17. So, how could I have had a machine shop "back in the day"?

On the same note, I have also noticed that we have similar thinking patterns. It does seem a little suspicious that he is the only one(besides pito) that actually takes note of what I say. .

[PoorManQ45]

If you want some serious power from your Q45, you need to go with Forced Induction.

Nope.

Overbore it to ~5.0. Then go with ~15:1 pistons. And change all the subsequient parts that would need to be changed. Mill the heads. Increase the valve lift/duration.

As Rex has said, that will make some serious power.

It seems that you guys think that we have 4-bangers in our Q45s. Why is it that when somebody says they want more horsepower, you automatically say forced induction is the only way. That is the thinking of a honda civics owner. We have enough displacement in these engines to make some serious horsepower, Without going witha turbo or supercharger.

[DAEDALUS]

Just bore it out huh? 11% more area? How much do you think you would have to bore it out to get 5L? .030? .060? Do the math--it's a fairly big number from a machining standpoint. And what's up with 15:1 pistons? You running diesel?

[elwesso]

Poorman.....

Thats true, but when we're talking reasonable HP, FI is much easier... $5000 will get you a supercharger setup with ECU, messing with internals and stuff like that is a whole new can of worms......

[HeavyDuty]

PMQ, buddy, if I just give you a pat on the bottom & send you home you'll get mad. So allow me to echo DAEDALUS' sentiment and SUBSEQUENTLY outline the specific inaccuracies about your statement.

1) You can't BORE only to achieve that much of an increase in displacement. You must have a longer stroke, necessitating a different (custom) crank, rods, and probably a custom piston.

2) 15:1 cr? You must be joking, unless you have race gas at every pump where you travel, or you retard the timing to...oh...1 degree BTDC.

3) Then mill the heads to bring the valves even closer to the pistons?

4) AND a higher lift cam to open them up closer still?

You're oversimplifying the entire process. Yes, there still is no replacement for displacement. Bore it too large & you'll potentially have cooling issues, stroke it too much & your piston speed will be too high, limiting high rpm capabilities due to the timing required for the event.

It seems that you guys think that we have 4-bangers in our Q45s. Why is it that when somebody says they want more horsepower, you automatically say forced induction is the only way. That is the thinking of a honda civics owner. We have enough displacement in these engines to make some serious horsepower, Without going with a turbo or supercharger.

No one said it was the only way. IMHO, it's the smart way. Even good standard rebuilt VH45's can't be found in the States, our +/- a hammer handle tolerances are not good enough.

There's many things you can do. It is more expensive & less rewarding to go all motor with a smaller displacement engine. I can install an aftercooled Vortech on a Honda B16 stock long block, at 10 psi, change the intake cam only to a JDM spec Honda cam, header, exhaust, and with no other changes yield 288fwhp/190tq. I can yield 246fwhp/169tq @ 8psi. That's a motor that only produces 160 hp at the crank, stock.

Spend the same amount of money *or more* on an all-motor build, and maybe yield 190 or 200 wheel? I'll take door #1 Monty.

To properly rebuild your VH would run 10k easily, not including all the big baller stuff you mentioned. Does it make sense to spend twice as much money for the same result?

I thought that would contradict your mantra to the core, oh great PVC plenum hose man.

If there was a way to effectively convey tone of voice & inflection here, you wouldn't think I was a d!ck from my post.

[Rex Rich]

Remember Im the one who posted this topic and its one of the most interesting ones here. The goof that dosnt think I was a engine builder is just smoking out his a-hole. Whether I was a builder or not, is not the point (although its funny). Its the interest in making a Q more than what it is that counts!If psycho_medic would think this way he might have something of meaning to add! Hes just jealous, he wishes he put this topic up!

For more than ten years I have been in construction so I had to fill my head with a completely different way of thinking so I cant talk like a motor head these days!Believe me I wish I was still in engine building it was the best!

Heres where PoorManQ45 and I use different computers. I would go with forced induction on this engine. Over sizing the bore and going 15-1 is not a good idea in my o so humble opinion.

Keep it going!!!

[PoorManQ45]

Just bore it out huh? 11% more area? How much do you think you would have to bore it out to get 5L? .030? .060? Do the math--it's a fairly big number from a machining standpoint. And what's up with 15:1 pistons?

I'm sorry guys. I made my last post a little hastily. I didn't mean just overbore the engine. I meant overbore and stroke the engine.

And what's up with 15:1 pistons? You running diesel?

HAHA. Lets laugh at Daedalus for a change.

A Diesel engine running at 15:1 would run very poorly, if at all. They run at about 14~25:1

Yey, I corrected a smart person

[PoorManQ45]

Doesn't force induction increase the compression ratio? If so, what would the final compression ratio of the VH45DE at 4~10psi?

Here's a question. How hard would it be to design a supercharge so that it fits right up to the lower intake runners? If you look at the picture of the Mercedes engine compartment, you should see what I'm talking about.

If I may speak for him, PMQ, it was an expression. Your quoted cr was a helluva lot closer to a diesel than a 91 or 93 octane gas motor.

We never had this kind of crap here until lately. It's a trap, one has to call BS & ends up engaged in a diatribe that has no point, purpose, or benefit to anyone.

Has anyone else noticed the elders have refrained from replying to all these nonsense posts?

Why?

Because arguing on the internet is like the Special Olympics, even if you win, you're still retarded.

Here's a question for you. How hard would it be for you to open any modern book on engine theory/principles, design, or even tune-up and actually read a few chapters? I have an excellent recommendation: Engine Performance Diagnosis & Tune-Up (3rd Ed) by Chek Chart pub. It's almost $100 but I am certain that if you read even 3 chapters it would pay for itself by preventing you from wasting your money, your time, and (especially) our time trying to keep a match lit during the endless midnight trek of yours through the minefield of ignorance.

[pito11213]

So basically when someone suggest a mod that is not accepted by the "elders" or the "masses" the person that started that suggestion is considered a nuisance. He is considered ignorant and just plain wacky.

The elders "refraining" from posting only shows that they feel they have reached almost Godlike presence on this board because they have been granted that title by the people that inhabit it.

People that have gravitated to this site are people that either wanted to know more about their infiniti/nissan before they bought one or wanted to know what kind of mods were out there after they bought it.

If they wanted strictly information on how to keep their cars OEM or "stock" they would buy a factory manual or simply go to the dealer.

I appreciate most of the info and most of the info gurus here. I do however, do not believe in placing anyone on a higher plane of thought regardless of experience or whatever. I simply take in their advice and if I have a problem with what they said I would expect not to get the type of response that PMQ gets most of the time.

[psychic_mechanic]

I didn't mention before the small effect that increasing compression ratio has on HP. IIRC it's less than 8% gain per full point of compression in most engines. As part of a total performance rebuild, increasing compression is part of a performance package. Same thing with overboring, altough at least you didn't say you were going to overbore it an inch like I've heard from other people.

I don't think either of your personalities has ever built an engine, just read enough to make yourself dangerous.

I'd suggest http://www.howstuffworks.com or http://www.gaymechanics.com for any questions.

[IvoryJ30t]

this got out of hand.

let me stress one thing.

the VH is by no means a "simple" engine. comparing a dinosaur like the ford 302 or SBC to the DOHC 32V VH is rediculous. that makes me want to bang my head on my desk.

if you have never built an engine before, the VH is not the place to start. ive built 500 hp 4 cylinder motors, and i do not have enough tools to do a proper STOCK rebuild on the VH. most machine shops lack measuring equipment with enough precision.

clearances are measured in ten thousanths of an inch. you need various micrometers with a precision of 5 hundred thousanths of an inch.

as i stated, a set of 5 capable micrometers comes out to around $1,500. just to be able to mic out components.

oh, and if you were to try and bore the VH out to 5 liters, you would have chewed through the liners and found yourself in the water jacket.

when some of us want to grow up, we will revisit the subject and take an adult view on the matter at hand.

[IvoryJ30t]

also, if you constantly used the amount of power that a modified VH could put out, you would most likely destroy it.

building for 700 hp, and only using 400-450 of it on a regular basis is they way to make it live. ceramic coating on the heads, pistons, and exhaust chambers will protect the components from the stress of 20 psi.

you cant use 700 horses for more than 10 seconds on the street anyway.

the infiniti cars have independant rear suspension, so drag racing high power domestics with solid axles and slicks is out of the question.

the whole point of this is to have a luxury car that rides well, handles nicely, and has a wicked set of teeth.

the reason i favor turbos is because your not limited to the boost of the installed pulley.

the ability to run the car in low power mode for normal driving [400 or so horses] is paramount. the high power would be reserved for times when you are on the highway at speed, with traction, and there is a viper or such that needs to be embarrassed.

remember, you need to be able to actually drive the car when your done with it.

basically, if your looking for cheap, easy power, your looking in the wrong place.
