So tell me, were you running the same amount of boost before you added that exhaust cam?

 

OH PLEASE KEEP ME POSTED I want the 1st one you get in.... put me on the list... RIGHT NOW

 

yes it was the same or I wouldn't have anything to base my prior runs on.

 

Okay so let me get this straight, you added Nitro as in Nitromethane to your gas? Nitromethane that doesnt mix with gasoline (petroleum) based fuels and even if it did that raises EGT's stratospherically? Nitromethane that is something like 110 bux a gallon? 15% of 14 gallons is 2.1 gallons.

You may have added methanol, but that is nowhere near the same. Next time dont post blatantly wrong information to support your power gain from a cam.

 

sorry I don't believe my info is wrong. even if I didn't run nitro that night have have greater pull at higher rpms. how do I know? I see it in my street racing . so quit trying to prove me wrong. I know how my car is and what it did before the cam. it is also my opinion if u don't like it look the other way. if u don't want cams don't get them. all u people do on this site is talk **** I swear. especially when there is a diff that I see

 

HKS does have some coming out for the MIVEC heads. I read it in Turbo anyways... they didn't give a release date though.

 

Wow...dainbramage at its best.

So, tell us more about this supposed "nitro" you use...

 

I guess u never owned a radio controll gas car? LOL ok MR stage 1 evo

im done with u guys ...

 

Wow...

If you have steal parts in the engine the methanol in the fuel is a hygroscopic, Which means it easily attracts and absorbs moisture. The moisture could cause rust and corrosion on steel engine parts if the fuel is not removed. While it burns slowly, there is also the danger of explosion when nitro is used, Plus you have to flush the fuel system and motor after each use. And when you were talking to me about it, You wanted to run straight Nitromethane. It would be very dangerous to do and you don't want to mix it with pump gas. It is possible and it has been done successfully. However, there are a number of problems that make this impractical. These include the corrosive nature of the combustion gasses after Nitromethane is burned. This process produces large amounts of nitric acid, which is not only corrosive but toxic. And again to prevent serious corrosion, a thorough flushing of the fuel system and motor is necessary after use. There is Nitropropane, which can be mixed with gasoline. Nitropropane and gasoline have been tested and shown to provide small but significant power increases. And you can't put it in with your meth/water injection, as nitro does not mix with water. It is hard to believe you are running nitro in you fuel tank, and if you have ever heard of Nitro RC's you would know after each use you have to do some sort of after run maintenance(Flushing the engine).

Sorry to go off topic, Back on topic. The only cams I have heard are from Turbotrix. I think cosworth and GSC are coming out with some as well. Never heard of any other, But I am sure there are going to be some more.

 

I too have only seen the cams from Turbotrix. Personally I don't see much advantage in changing the cams in the IX because of MIVEC. Thats the whole point of variable cam lift and timing is to have granny cams at idle and bigger lift at high rpm WOT. I'm sure there will eventually be some that will work with MIVEC to eak out a bit more power, but I just can't see it being anything tremendously significant. Especially for the price.

And Sesso.... I'd say you've inhaled too much of that Nitro.

 

actually you've inhaled too much nitro because there's nothing variable about lift with MIVEC. It is only variable cam timing. You do not have dual cam profiles on the IX cams. Don't confuse VTEC with MIVEC.

 

Glad someone pointed that out. Its amazing how many people dont know the difference between the two.

 

Actually MIVEC is like VTEC and is both timing and lift. However, the MIVEC in the Evolution is limited to timing only.

Ultimately it would be nice to know why the IX isn't seening much gain from bigger cams.

 

Yes, that was my bad. I didn't realize the Evo got a gimp version of MIVEC. I still love it though Big improvement over the VIII.
