11-1 Compression is the time you need more thanpump gas 87Octane. Don't even waste your money on 100+octane gas, buy 87 gas and throw Laquer Thinner in it takes care of the ping its what works well. On my Brothers 327 Small blockChevy motor with 13-1 compression he runs laquer thinner and its all crisp power and youCAN tell a difference its quite amazing, and this motor is dyno proven at 568hp so its not some stock 4 cylinder that you won't tell a difference in if you put it in other than for gas mileage or turbo equiped. When a motor is pinging you notice it and when its not pinging you notice it, the Laquer thinner makes it not ping.

The turbo is the easiest way to make good amounts of power with little effort. I run a stock sohc with a turbo at 8psi and my Gtech tells me 202Hp to the wheels, even if thats not dead on acurate it is close, I'd like to see NA Neon motors do that and get 300 miles per tank of gas like my stockTurbo sohc.

Save the NA for 8 Cylinders. Turbo all the way for 4 cylinders.

 

slash not trying to be mean at all or tell you that your way is wrong...

however if I was to go and do a compleate performance based build up of my motor and sink 3 grand into it... I would not want to start throwing thinner or anything else in my gas tank... I would want to know that the minimum oct. level in my car is a certain oct. and not just throw some thinner in there and hope ithrewenuf inor thorw too much in... I guess whatI'm trying to say without being disrespectfull is"IfI didentuse ghetto parts, I'm not using Ghetto fly by night gas"

Like I said 2 other times I dont mean this to be disrepectful at all slash just my opinion...

If the kid wants to go NA let him... I love powerfull NA cars,there throttle response is absoulutely sickening.

If you were to get into Jeff B's 2.4 NA car you would **** yourself... He's running 12.31 @ 111.51 - 235WHP/186WTQ on a NA 2.4... come on that insane... wanna see a dyno pull???

wanna see a dyno sheet???

thats the difference between crane 24's that he made the 12.31 run with and the crane 28's that he has in the car now... yes crane 28's i did not mis-type... only set that has ever been used. This is the same guy that makes booger bushings...

You tell me you wouldent have fun in that car... let alone say screw the turbo idea...

 

this is a myth. that will just lower your mileage andcontaminate your oil

 

Wheres your source Mythbusters?If so then I laugh. Mythbusters used a 1/3 ratio, You only need2-3 ounces per 12 gallons, thats why theirs guzzled gas.

Quit being an ignorant ******, I've been running the **** in my car for 2 years and my brother has been using it for 8 years. If you don't want to use it thats your choice your loss and everyone elses gain.


95-96transplant, I'm not doubting the power ofa NAmotor, I just think the priceand all the energy involved to get that power doesn't seem worth it, I got aTurbo kit I pieced together myself and spent under $150, and I didn't have to take my motor out and send it to the shop to havelots of work done to bore it out and buy performance parts and everything else, I spent $150 and have 202 wheel horsepower with a bone stock motor. What i'm saying is can you make a NA motormake 200+hp on $150? hell even $500 if you want to consider the ebay kit that everyone can buy.

You don't need $2500 to make a awesome reliableturbo kit, 80sChrysler 2.2s run the same turbo set up I run and it lasts20 years.

If the person has the money and wants to fk around pulling the motor and rebuilding itlet him go Normally Aspirated. The NA motor is gonna guzzle more gas when built up than a Turbo is gonna. I guess I'm having my cake and eating it with the price x Horsepower my set up gave me.

If Money doesn't matter and Gas Mileage Doesn't matter then Nothing beats a NAwhen comparing 500hp of NA powerto 500HP of forced induction. Like you said the response is beautiful.

 

how do you figure a na motor sucks more gas then a turbo???

 

^^ i was kinda thinking the same thing!!! lol.... cant wait for the responce...., the ONLY way u can use less gas is to keep the car out of boost, and what is the point of runing a turbo if u stay out of boost?????????

 

funny thing:
when i had the turbo on my red r/t i was getting about 27mpg......
got rid of the turbo but kept the same motor....now i average 21mhp

 

^^ LOL, yeah, i get about 25 with my turbo setup.....

 

When I had my timing beltand head gasket replaced at 120K, I put in a mild grind Crane cam and milled the head to set the dynamic compression ratio to 8.5:1. From my research, at sea level, this is is the optimum compression for an aluminum head, computer controlled, NA engine running 83 octane pump gas. This set the static compression ratio at around 12.0:1 - but the static ratio is not important.This added about 40 HP to my SOHC and noticable torque. With more cam, you could probably push 60-70 HP out easy, and still run 83-85 otcane. For a DD, I'd just run the high compression, I think turbos require more maintainence (just my 2 cents.) As for the laquer thinner, it's an old trick. Mothballs, naptha, it all does the same thing, in fact Shell Oil got their tit in a wringer because they were adding benzene to raise the octane levels in their premium fuels.The EPA went nuts. The problem is, it will destroy any rubberengine gaskets over time that come in contact with the fuel. Old diaphram fuel pumpsusually only lasted a few months.

 

DO I really have to explain this?...lol

What happens with forced induction? it atomises the fuel better! This is not me saying it! Its Automotive performance 101. Turbo cars do get better gas mileage than NA cars, but alot of times its hard to tell because you can't resist getting on the gas because you know you have that supply of extra power. If you were to Drive a NA and a Turbo car the same way the Turbo would get better gas mileage due to it being able to atomise the fuel better.


Don't believe me Turbos get better mileage when driven responsibly thenRead this: http://www.allpar.com/fix/holler/slant-six-turbo.html
