That RLF post is outstanding. Moarrr discussion here please!

 

Does your car go super lean in 4th gear?

 

I havent gotten it that high many times. I did do a couple pulls to 6500ish in 4th and I still had fuel. I dont really like going that fast. I think once I free up my exhaust I will start running out of fuel.

 

TVS/E85/80#s/and 2.9 with full exhaust

maxed out 80s at top of third on E...granted im a little rich cuz i needs the help with the fuel trims




Return style is a must...will be the only thing allowing me to pulley down or even install my ported head on this fuel

 

where is the timing? I think my stockish exhaust is keeping me within the injector limits.

 

The HPT chart shows 17*...

 

skatin...i would love to see your tune file man...i am totally new to the e85 tuning...send me an email if you wouldnt mind

I was giving him crap. Ramp it up to 25*. No need to stay on gas timing with ethanol in your tank. Thats the reason we use it.

 

care to give me a hand...?

 

Ya I misread your post, I thought you were asking how much lol.

Vaughn, bump that baby up to 25!

Must be nice to have E85 around. The low octane is killing my TVS fun lol. I have E85 about 20 miles away (the opposite way of where I work and regularly go as well), but that's a long way just to drive for gas...

 

Is this BRFPS functionally equivalent to a return style system minus the return style part?

 

nope return style keeps the pressure at a set amount as the boost referenced actually raises the pressure as you get up past 17.5# of boost.

 

So can you explain in which circumstance which is used, and which is better for what? Thanks!

 

They both have thier strong point and both decent system, I have no experience with the fuel system changes as Im still stage 3 pushing out less than 17.5# pounds of boost.

 

Well thanks. I'm still trying to figure out what each's stong point is, and what is a better application for which type of setup. I'm going to likely need it so I can run my 2.8" TVS on E85.

 

If you want to run e85 from what I have read on the forum go with the return style so that you dont starve the number 4 cylinder thats what I have read and I dont know how Viable the source is.

 

Ya, I'll have to research it some more and then decide. It won't be for awhile anyways.

 

It mainly depends on how far you want to push your fuel system.

The ZZP BRFPS should be plenty to run a 2.8" pulley on a TVS with E85. But it may not be enough to run a 2.6".

That is what I would base my purchase on if I where you.

No one has proved that the failure of #4 is because of fuel starvation. That is a forum rumor.

Most people think it has to do with the cooling pockets around the #4 cylinder. That is the reason GM increased the cooling capacity of the Gen II ecotec block by .5L.

 

Good to know that's why I said I didnt know how viable the information was thanks for the input!

 

Thanks for the insight. Can you explain how each system works? What their intended application is? Tuning issues with both? How about boost reference with return style?

So if common sense reads right from your post, the return style will flow a whole lot more? Two pulley sizes doesn't seem like a lot...

Is the LSJ block a Gen II block? (Over the Cavalier Ecotecs?)

 

Your going to have to do your own research for that.

LSJ, L61, LK9 are Gen I.
LNF, LE5, LAF, LAP, LE9, LAT are all Gen II.

 

Thats kinda rude coming from the guy that demands proof of cars that have cracked 300whp, when many have done it years ago... Sorry, reading css.net jibberish is not 'research'... I'm not asking for you to write me a book, but some links or other info are helpful to myself as well as thousands of others on this website. I guess that's why this place is .nub and Cobalts are still slow...

Nobody wants to share anything to advance our cars.

 

lmao!

Kids...

I am not demanding anything. I asked who has broke 300 and let people throw out all the names. Then I did my research to find the truth. w/e

I have provided more information in this thread then everyone else combined. And your going to call me out? lol

 

I don't e-fight, sorry, so I won't respond to another thing you say.

</threadjack>

How about some fuel system tech talk!

 

You're on the wrong site for tech info.....
