• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Thinking of converting to E85.. Yes or Ne??

Well I'm doing it! Just ordered 3 high quality gas cans off Amazon haha. I drove to the E85 station today to pick their brain a bit. I asked how long they've had it, how it sells, if they ever sell out, etc.

They've had it for 4 years and it sells very well. The clerk said a lot of Subaru guys often travel to get it and fill up gas cans LOL. Overall, the commute took me about 35 min each way.. 90% highway. Not too shabby..

Hopefully my 115K L67 bottom end doesn't go boom.

How many bottom end failures have you heard about? Rod/piston failures come from to much knock.

Failure points are in the tranny. You will break stock tranny parts like input shaft or chain before bottom end.
 
Yeah usually bottom ends go on rebuilt motors for some reason. Stock blocks are pretty strong and another 40 or 50 hp should not be a problem for your motor. A good tune on e85 should result in little to no knock. One thing to keep in mind is that cold weather e85 is actually a different blend and not true e85. Cold weather "e85" has less ethanol. I don't remember if crbquist mentioned if he would be driving in cold weather or not.

I don't drive it much in the winter.. Maybe a few miles here and there to keep it moving, but that's about it.
 


The bottom end might be worried if you are up over 800whp.. even then I probably wont be too worried if you are shifting under 7k.
 


You probably should have installed a roller timing chain with your cam and 105 springs but your stock chain is new which helps. I don't think at this point the extra hp you will gain with e85 will make a difference on the timing chain. I think the 105 springs will stress your chain the same with 93 or with e85.

I was originally gonna go roller, but was told by many members here that a stock chain would be more than fine for my setup. I was thinking that the extra hp would stress the chain.
 
I've read that general rule of thumb is stock chain for rockers and 90 lb. springs, single roller for mild cam and 105 springs, double roller for big cam and 130 springs. Its the springs that stress the chain but im sure you will be fine with your set up for a while.

Some say a stock chain is better than a single roller. Also, 90 springs are harder on the chain than 105s because of the ramp rate. I'm thinking I'll be just dandy. But then again, ya never know... Danomite just snapped his single roller yesterday..

I've never heard that a stock chain is stronger than a roller chain and have a hard time believing that 90 lb springs are harder on a timing chain than 105's but I've also never scene any actual evidence to say either way. Rollmaster claims otherwise however... Good luck with your e85 conversion
