E85 gains with vq35de?

E85 gains with vq35de?

Hi everyone, 

Just bought my first Stagea a few days ago, a 2005 350rx.

Just wondering if there is anyone here running E85 on the NA VQ engines, and whether there is much gain to be had?

My last car was a turbo mx5 which was running E85, and that saw noticeable gains.

 

My to-do list of mods will include (but are not limited to):
-plenum spacer
-z-tube intake
-exhaust
(any other easy recommendations are welcome. don't want to go too expensive)
 

 

Thanks,

Nic

You won't see any gains unless you install some means of tuning.

 

[NicPM35]

Yes of course.

Ok well then you could pick up a few KW but given the difficulty of ensuring a constant supply of E85 you would probably want to run a dual fuel set-up which may make the whole project uneconomic.

Yep, had a Flex sensor running on my mx5. I know how to do it, just wanted to whether anyone here is doing it with the Stageas with success really

On an NA motor designed for 95/98 it'd be a bit of a waste as you'd be increasing your fuel consumption and cost (in comparison to running 98) for zero / absolutely minimal benefit from the extra octane. There are a few people around that have done this kind of thing on the turbo models but on a stock NA the drawbacks and cost significantly outweigh any benefit that you could expect.

On the other hand if you are planning on fitting forced induction or going for big compression at some stage it would be a well worthwhile bit of work!

I think the VQ motors are pretty high compression - 10 or 11:1

Your list of to do mods doesn't include an ecu or piggyback... So by the time you do that plus flex fuel, it's not going to be a cheap exercise for very little gain.

Do a proper exhaust, use the E85 money for exhaust manifolds (coz they're cool).

Don't know if the NM35 has a separate ecu for the auto otherwise this may plug in:

*sigh* if only things were that easy for the rest of us.
