Easiest way to boost compression on stock 3.0

[Exitwound]

E85 will reduce your power output when compared to gas. the reason for that on your typical car is that the comprssion is not high enough to take advantage of E85s properties (directed at AIrcraftMech) so your buddy with the titan is right. E85=less power and worse milage on a engine optimised for gas.

to convert the fuel system you will need.

fuel pump
Stainless Steel Fuel Lines
injector O-rings rated for E85
FPR rated for E85 and one that will pass a higher volume than stock
larger injectors that are rated for E85
tweecer to tune
turbo or S/C +related parts or new pistons

1slickred89 converted his turbo ATX car to run on E85 and had good results. I had planned to do that to my turbo ATX as well but the fuel is still not avaliable in my area

the good:
cooler intake temp
lower EGT
reduced detonation

the bad:
increased fuel consumption (richer AFR)
if you stay N/A you will be disapointed
you will not be saving money

Since alchohol naturally draws moisture out of the atmosphere every thing that comes in contact outside of the engine block has to be stainless steel. Then all of the rubber has to be replaced with rubber hose made for alchohol. It would be a ton of work but worth it in the end. Since alchohols BTU is far less that gasoline you would need much more of it to get the proper air-fuel ration in turn reducing the mileage you vehicle will be able to travel. The plusses will be a motor that WILL last longer and run better.

just build a water injection system thats nitromethane compatable and run 40% nitro, 40% alky, and 10% water

make sure your tank for it is 10 gallons, your jets provide a fine mist, and that you have a spare engine laying around

and 10%... what?

40/40/10 only adds up to 90%

 

[HotRodKid]

haha,

10% magic additive ?
10% heaven help ya additive ?
10% of your friends telling you its a bad idea ?

theres many otptions ....

or just go 40/40/20 like i originally meant to say

 

[yamahaSHO]

True words Racer X. E-85 is not made to be used in a regular engine. After you up grade ALL of the rubber components in the fuel system then you can go out and try to find someone to reprogram all of the perimeters in you computer

Reprogramming parameters around here isn't exactly hard to come by...

It's not worth it due to the fact that it would be cheaper to go out and by a newer car that will take either type of fuel.

My car is probably already prepped for this and I can garantee you that you cannot buy a car with the amount of money I had to put into the fuel system.


I have considered trying this route in the past, but with my lack of motivation to do anything new on this car, I've stuck with good ole 91 octance and a good tune.

haha,

10% magic additive ?

Shhh, I though that was supposed to be a secret

10% heaven help ya additive ?

10% wouldn't be near enough to help me...

10% of your friends telling you its a bad idea ?

Doh, in my case it's more like 90%

theres many otptions ....

or just go 40/40/20 like i originally meant to say

Oh, that'll work too...

So I purchased a set of heads from Eric, and I will be trying to fill in the combustion chamber with a bit of weld.

First I have to see what alloy the heads are, if it is weldable, and then I need to find it's expansion coefficient. I will be trying to fill in the space on the side of the combustion chamber. I calculated that I need 8-10 cc's of metal to boost it to a high 12 - 13:1 compression ratio.

Have you talked to anyone about this? We have the most beautiful, un-shrouded heads of almost any non-race car. And you're going to weld material into the combustion chamber,... and what was your initial intention again?

You need to go and talk to some old school engine builders. Not the short block guys at VatoZone, some real old school big block roundy round guys.

its the same general design that ARDUN used way back when to make 300hp flathead, 300 HP FLATHEAD !!!! .... the same flathead with flat heads = maybe 150hp

adding material around the valves will only cut off flow, so great, higher compression... except your getting less fuel / air to compress

and here i am looking at the sho head on my desk thinking "i should pull my heads and open up the chambers some ....

Funny you should mention Ardun. At a MetalMeet (A gathering of metal shapers, worker and mostly hot rod types) that I hosted at my shop a few weeks ago, a hot rod with Ardun heads showed up. Truly a thing of beauty.

End Hijack.

Custom MLS head gaskets .

[redwraith94]

I want to boost the compression ratio, to make use of e85.

Thanks for the linky, any idea how much the custom head gasket would run for the sho?

 

[HotRodKid]

true, sho's need 40% of that additive just to crank over in the morning ..

10% of your friends telling you its a bad idea ?

Doh, in my case it's more like 90%

true once again, almost everyone that doesnt own a sho thinks modding sho's is a bad idea

and then they think modding shos is an even worse idea when they get whoomped on the street or at the track by one

ardun originals or the 1990's run of 70 sets (67 sets were sold) that wer made by the guy that bought the rights and all the blueprints ? lol

Zora Arkus-Duntov was an automotive GOD, simple as that

i was just looking at the grand sport (duntov) corvettes yesterday, omg yea

edit again: oh yea, im on metalmeet too.

~HRK, all over the interweb since bob dole invented it~

Here is the best view I got of the head.



This guys runs it at the Salt Flats. What a hoot that must be.

I'm really wondering were you got the idea to weld the head, slap that person in the head. I don't know that much about these SHO motors, but to build C/R get some pistons, and open the heads up.

 

[redwraith94]

egroce11, what is the highest Compression Ratio pistons that you know of? I only see the wiseco's for 12.5 to 1, I don't know how much higher e85 could go, than that, but I am guessing 14, to 15 to 1 for ~ 100-105 octane?

About 12.5 to 1 is really the most I've heard of. I just got off the phone with a person running alcohal (spelling) he breaks stock pistons and has just ordered 12 to 1 wiscos.

If your going to raise the CR do like everyone tells you, get some pistons, shot peen the rods, new bearings, open the intake and the exhaust. I don't know the differance but I run 110+2 race fuel and have no known problems, but my motor is built differant than other motors on the forum.

 

[redwraith94]

How many pounds of boost was he running on alcohol?

 

[egroce11]

How many pounds of boost was he running on alcohol?

He runs N/A, I believe, with individual stacks and hildibrand injection system. He's trying to get the info to put this system on my car except to run race gas.

 

[redwraith94]

What are individual stacks? I don't know what a hildibrand injection system is...But I wouldn't blame the piston failure on running alcohol.

I know the Wisecos are by far better, but i don't have 800 dollars to plunk down on pistons, plus the costs of boring / honing, and balancing.

 

[egroce11]

I don't know why I put "I believe he is running N/A" because I know eh is N/A.

Yes the piston failure was because of the alcohol, due to low compression ratio and the fuel not burning right.
hildibrand inj. is an inj. system company.
Individual stacks are just what they say. Individual stacks to each cylinder. I'll find a picture of some and post it.
I'm not trying to be mean or a wet blasnket, but for the project you are want to do,, you need to save some money and do it right, or and I hate to say this, but go with a turbo or s/c.
