These are some very nice results on pump/91. Is the intent of this thread to get a "Pump 91-Octane Dyno Results" thread of sorts? I think this would be a great idea and maybe someone should engage a moderator or something. In March I will have my EF4 tuned with all of the bells and whistles. I will be happy with 500whp and 375wtq as I will be on the stock bottom end.

...My next mods are Evo 8 stock ported intake manifold (right now I have a evo 4 stock intake manifold), 65mm or 70mm throttle body, Speed Density, Perrin filter and new tune with Tom. I hope to get 500 whp with those mods and tune.
Good luck with your car and goals!

Hello, my friend. I have no doubt that you will achieve those levels once you install the parts listd for your next phase. I know that the EF4 can achieve those goals as well but since my engine has 107K miles on it, I want to play it safe during tuning as I am getting a MAP 2.3L this summer and I need the car to survive. If you are willing to wait, I will have an intake manifold for you as a possible core once I have the Rev2 installed.
Thanx but last week I bought a ported intake manifold.
... good luck with your project!

yea Pure evo thats what he wanted was a dynograph of what similar cars do on 91 octane. To be honest thats whats holding back my power, is 91 octane, mind you that car was tuned in a 107* ambient dyno room in the middle of summer, here in the inland empire in cali it gets real hot summers. So eventually once its paid off going double pumper bigger injectors, have my tuner push my fp red to make 30-35psi of boost, make 500 hp 500 ish tq I hope. But I have a good year to year and a half before paid off.

@ Boosted your graph looks good, but imo, i know the 280s have more duration then my older hks 272 cams, but wouldnt a swap to the gsc s2 cams, lead to more midrange and top end power, thus increasing your midrange torque and top end horsepower. Just a thought. Your graph looks good, but with like any bodys car a certain part put on helps the supporting mods flow a lot better.

Just off the cuff though, I would suspect that your pump + Meth/H2O mixture is a higher octane brew than straight 91 octane pump gas.

The final octane number obtained when mixing known 89 octane pump gas with H20/Meth depends on several factors. First off: What mixture of H20/Meth are you injecting(50/50, etc.)? Also, exactly how did you determine that your available pump gasoline was actually 89 R+M/2? Was the knock resistance of an actual sample of the fuel analyzed by a fuel lab?

I found water on the walls of my fuel tank! the gas station here in my country mix water with gas!, the same with Costa Rica and Panama.
I have a mix 50/50 with h20 and meth.

Yeah, don't forget that you and I are neighbors as I live next door in Honduras. If your country gets its gasoline from Venezuelan refineries(PetroSur, PetroCaribe), then we are talking some of the worst pump gas available anywhere.
Here in Honduras we have terminals on both the Caribbean coast and the Pacific Coast. The Caribbean terminals get there fuel from Arruba I think. Whereas the Pacific Coast terminals get their fuel exclusively from Venezuela(crap). El Salvador only has Pacific Coast terminals, or else the fuel would have to be trucked in across the isthmus from Puerto Cortes, or Puerto Barrios.
