Making my fuel higher octane?

[Astaldoath]

Anyone have any cheap ways of doing this. I plan on adding a cold air intake (yes its actually cold air) and a smaller supercharger pulley to my 07 grand prix gt. I will need higher octane gas ( i assume) and possibly to adjust my ignition timing to prevert knocking. Just lookin for some advice before i do this. Im also thinking of getting a 75 hp dry nos system but only after i get more cash.

You should not need higher octane fuel, not with that motor. I may be wrong. If you want to increase octane just go to your local parts shop and pick up a can of octane booster. I think you can get as much as a 6 point boost from the different manufacturers. Combine that with a 91 or 93 octane fuel and you should be set. Before doing this I reccomend consulting other sources as well, could cause damage.

avoid dry N2O systems. go for direct port (i think thats what it is called) or wet.

For your supercharged motor Keith would be correct... You're gonna want to go with a "wet" system and as for your octane, if you're running premium (93) then you won't need to have an additional octane booster.
One thing that I would definately recommend is that you change your oil to something better... I would say Royal Purple, Amsoil, or Lucas... Also you'll want to look at upgrading your wires (to 8mm) and probably better plugs if you haven't already.

A super charge pulley?

I know Fast Forward Performance makes "Under Drive" pulley's.

Basically it spins your accessories slower, making less drag on the crank.

Maybe a cold air intake and leave it be :)

^^ I agree... If you put a new pully on the car you could mess up a couple timing/crank/firing issues. Just do the Cold air and if you think u need more run a forced air tube and do a forced cold air induction. That will give u a couple HP

u have to becareful switching plugs with a superchager get the wrong temp and bad things happen.

Ok, I heard a dry nos system is safer. That is also the kit 3800performance.com sells. Im running 92 octane, so 93 will probably be the most I need until later when i put in a camshaft, ls6 springs and all this other crap they sell :D, possibly a turbo :D. Im gonna get some copper core spark plugs i think they have 3 heat ranges.

The reason I was asking about higher octane fuel was because they say anything smaller than a 3.5 pulley (3.8 is stock) and proper measures have to be taken to keep knock retard down. They dont elaborate on this. I spoke to one of the guys at 3800performance.com and he said dont run anything more than a 3.5 pulley on a stock motor. Im guessing its either because of boost levels being to much or because you will need to advance your timing/run higher octane.

Thats why i think they are saying dont run a pulley under 3.5.

Hold it a second... Am I reading this right?
You have a superchargered motor... correct?
And you want to put a Turbocharger on it?
Sorry son, but that rooster don't fly.

And if you plan on making the rest of those mods (besides the turbo), you're definately gonna want to get better oil in that puppy...
And wet systems have come a long way in the last few years and will work much better with a forced air induction system (a.k.a. supercharger or turbo)... The only perfectly safe Nitrous system is one that you don't put on your vehicle... And keep in mind I AM A BOTTLE BABY :), so basically what I'm saying is "If you put nitrous on your car, doesn't matter if it's wet or dry, if it's done wrong, then bye-bye motor."... so make sure a professional that is familiar with nitrous puts it on as I've seen to many kids try and throw a 150 shot on a stock Civic and I'm sure you know the results of that.

[CaptainPioneer]

Personally, If i was ever going to do a Nitrous set up... First off... Even though a Wet Setup is optimally better for performance... I would stick to a Air Intake Dry System only because its not insanely out there as far as performance goes and like CarGodz said... If its done wrong you can blow ur motor.

From what i understand, you should upgrade your Pistons, Crank, Seals, And Gaskets and INtake Manifold to accomodate for the extra ignition....

This is all i really know from watching HP TV on the Speed Network lol

[Ryan from Ohio]

Well the 07 GP's have a 3800, or a 3800 super charged. He obviously doesnt have the V8.

Anyhow...

If Im understanding him right, I think what he is calling a super charger pulley is simply the pulley on the crankshaft. Some places make this pulley and call it an "under drive" pulley. It simply spins the accessories slower and is less drag on the crank.

If your motor is already supercharged, you cant turbo it :p Mike covered that.

If its jsut the standard 3800 I wouldnt even consider turbo'ing it. The block just like all GM blocks can take much PSI...

Please refer to this link all who are saying I cannot turbo my supercharged motor. And no the pulley is the pulley on the super charger. Im not a pro but i did look into this before i start talking shit and risk looking like an asshole.

$3,200?

All for what? A little more speed? less gas mileage? Higher chance of blowing up your motor?

I cant see it. But then again many people cant understand the investment most of us make in Audio...

Im not gonna turbo it until i need to rebuild my engine so i can make sure everything is up to par lol. Yes i invest a lot in audio too so im right there with ya.

infact im not gonna do cam, head, crank or anything that involves dismantling my engine until it needs or almost needs done. Cause if i plan on hitting 500+ hp ill need a new tranny anyway :D

[Chris from MI]

Hell, just buy an LS2 and cram that bitch in there. Then you can push almost 600HP on stock internals and be safe.

[cargodz]

Ok, Now I see... The kit actually ditches the use of the factory supercharger, making it basically a 3800 that gets Turbocharged as a conversion... Although I can appreciate their effort in designing something like this... You hav to admit, kinda defeats the purpose of buying a supercharged 3800.

hahaha yeah nevermind, I just saw the words "Block off plate". I doubt ill do that then hehehe.

If i can hit 350 hp without engine work ill be happy.

[GlassWolf]

bigger fuel injectors, higher rate fuel pump, and if you want to boost octane, you need to use Toluene.

[GlassWolf]

also, free flow exhaust and header(s), and gasket match your head(s) and intake.
gasket matching the TB and headers doesn't hurt either.

[Darthness]

nitrous can be safe if you're not greedy with it :P yeah, a 150shot on a stock civic engine is a disaster but if smaller shot would be safe if the driver isn't a retard.

And i've always been told to avoid dry kits completely. Many people i've talked to say that a direct port or wet system is much better and much safer?

Also, whats wrong with twin charging? :P

[breakjunki]

FOr a second, I thought that kit allowed both the super and turbo. I didn't think that was possible, now that i read it further it isn't :). I've had a few cars with a turbo setup. I like a supercharger way better, with turbo you have a lag somewhere in the rpm range, but Its sweet when you get in the boost range. Superchargers just provide solid power across the whole rpm range, for reliability I think superchargers are way better, don't know why you'd get rid of it.

[breakjunki]

whats your HP stock on a V6 supercharged? 350 doesn't sound to hard to pull off.

[Bwcad1]

supercharger and turbo is possible.

[GlassWolf]

the wet systems are preferred because you run less chance of leaning out the AFR and cooking some pistons.
That's essentially how most people kill motors with nitrous.
they run too lean.

BINGO!... We Have a Winner! :)
And you have to keep in mind that wet systems are designed for forced induction, as long as you're not running lean you're in good shape... Heck that's essentially the rule of thumb behind every internal combustion engine, not just forced induction motors ;)

Im makin 260 hp stock and 280 ft lb of torque. Id like to hit 350 hp and 350-400 tq without engine work. Dunno if its possible or not.

I mean like just CAI, Exhaust, manifolds, headers, pulley.

[cargodz]

Well your simple add-ons such as exhaust, Cold air, pulley, MAF upgrade, Royal Purple oil, upgraded wires, NGK plugs... all of these should free up somewhere around 50 ponies...
Notice I said "Free up"... as most of these do not actually gain hp, but actually make the motor more efficient in how it performs, thus "free up".
So you could get somewhere between 290-315 at the crank without Nitrous or any major modification... Although notice I point out that this is crank HP and not Wheel Hp... You can easily account for a 10-20% loss from the crank to the wheels, but the only real way to know what you've gained would be to go hit the dyno now and then again after your upgrades.

[GlassWolf]

also, port match your head(s) intake, TB, etc.
thi'll free up more power, too. also, free.
with all of this work though, the most you're still looking at with a mostly stock motor is about 300HP and 330lb-ft peak.
building horsepower isn't cheap.

as the old saying goes:
1: Fast
2: Cheap
3: Reliable

pick any two.

[cargodz]

building horsepower isn't cheap.

I tell that to people all the time ;)
