Which one?

The only motor ive had that had top end damage was the one that wasnt using meth...the one that bent the crank the top end looked fine, hell im even reusing the pistons in my current engine!

Fuel choice doesnt blow up engines, shitty tuners do

...says the guy that blew up an engine, but learned his lesson.

 

Are u guys saying a apples to apples comparison 93 and meth to 85 dyno the e85 will make more power?

I think that meth and pump would because e85 Great advantage is the ability to increase timing. That's where a lot of the power is made right? what makes ~20 psi the magic number?

20 psi 15* 93 and meth vs 20psi 15* e85

Gadgetized is the key to this test.

 

E85, if available. Gas mileage is worse, but honestly I lost more mileage with my injectors than I did going from gas to ethanol.

 

If you lost mileage due to switching injectors your tune is bad off. I was running 13-14 ° timing and 20 Psi on 93 and 2 m15 nozzles of straight meth. Shell 93 always from the same station and I watch and log the afr after every single fueling event. Matter a fact I log all driving with new engine.

 

Afr was always between 11.2 to 11.7

 

if your running only 15* peak timing on a stock iron block truck motor on e85 your either playing it extremely safe or need to go back to tuning school ... lol.

 

That was said just for comparison sake I believe. I think we all know you can stretch the timing up some on the corn. (one of its benefits for sure).

 

I was told by a very reputable tuner/dyno shop that E85 is worth up to 50rwhp over pump 93 on the dyno. Plus the added cooling effect it provides for forced induction applications .

I would run E85 if it was more readily available .


Now here's another question if you guys don't mind , can meth be used in inconjunction with E85 ?? Would there be any benefit ? ( not sure what the final octane / quality would be , or if they are compatible ).

 

23-24* timing seems pretty aggressive, even with E85. When I dynod mine I had 14.5-15* in it just because I was just getting the baseline tune it in. I haven't had a chance to test the file I wrote with 18-19* in it before the 80e starting making some nasty noises and it's been parked since then.

All other factors controlled, will increasing timing in boost result in increased fuel consumption? My logic says no but I want to hear from someone smarter than me.

 

E85+Meth would only help if your IDC was getting too high IMO. E85 already does a sufficient job of cooling especially on intercooled vehicles.
