In TT you don't need to do a 25-30 min session, 3-4 laps is all you need then you're done because you'll catch traffic. in that situation e85 would be worth while. Blackenwings was talking about doing DE in addition to TT and I believe he has a second driver/coach, so his car will likely see a decent amount of track time.

I wish e85 was available around here in the NE. I would run it in a second if it was and know a lot of other people would do the same. IT has some great advantages over race gas.

 

if E85 was available at every pump in the Northeast, i would run it for sure, or if i was trailering my car. but i would still run 93 for DE. you dont need all that power to have fun at DE, i usually turn the boost down to 18 psi for DE anyways.

my friend did his first DE event after 5 years on a track that he hasn't been on, so he wasn't driving as hard as i would and he burned through a tank of E85 in a 25 minute session.

 

Absolutely agree, no need for max power during a DE. I only run 21-24 psi max for DE, and cheap street tires. The car still pulls like a stabbed rat. I trailer my car, and don't mind bringing fuel, so E85 isn't a huge issue for me especially since there is a pump 5-10 minutes from my house.

I probably won't be doing much more DE events at this point in the Evo, as I'm planning on all timed events next season. I'm still picking a series, but leaning towards Real Time Attack (RTA) at this point as they run at all of my local tracks and I know some of the folks involved in it. My car is legal for Global Time Attack (GTA) GT Street class or the equivalent class for RTA with just a MilSpec catalytic converter thrown on, and I should be very competitive in that class and Hankook RS3s are pretty similar to what I'm used to running in DE and are the stickiest thing you can run in those classes. If I wanted to be competitive in NASA TTU I would need to be running on A6s and running E85. NASA MidAtlantic has some really fast C6Z06s in TTU with a ****load of power and downforce running on A6/R6s. Not to mention cars like the Element Tuning STi... which is um...12 seconds faster than me at Summit LOL.

Fuel consumption is somewhat of an issue but for DE you are running for 25 minutes at a stretch which is cooking the car anyway, so I don't mind running much shorter sessions and more of them. E85 will be totally fine for that. I would target ~40 gallons for a weekend of timed sessions. Granted that is WAAAAAAY less than I'm using now, so I might be underestimating how much of the corn I'll drink. I also splash a bit of 100 octane in, so my fuel costs for DE add up fast.

My coach isn't co-driving the car any more, although he's still instructing me it's strictly off track coaching, although he might ride along with me on tracks I don't know yet.

 

E85 widen's your powerband... and significantly improves your spool.... and has a higher knock index!

 

Yeah, I'm looking at injectors right now. I'm thinking FIC 1250cc BlueMax should be about perfect for my goals. The main question is pump options, and I'm seriously considering the Squash Performance offering. I've heard horror stories about the Full Blown double-pumper, I don't buy parts from Buschur, and my other option is a surge tank and in-line pump which is an unnecessary cost if an in-tank twin-pump option can do the same job.

 

Buy a single walbro 400 made for Ethanol. It'll do almost 600whp. no need for a double pumper.

Run the EV14 style injectors, not the bluemax crap! Injector dynamics FTW.

 

Love my FIC 1450's (sorry R/T)... Like R/T said just get a Walbro 450 and be down.

 

Hmm, 600 whp would be well over my needs, so if a single Walbro can handle it... that's a done deal! Which pump are you using Tim? Link?

Also, do you run 1450s with just E85 or do you ever run 93 as well? I figured the 1250s or something similar would be a better fit as I could still hit my target goals of 500-550 whp DJ and have a bit easier time running on 93 when I need to.

 

I am currently on my 2nd Walbro 400 (non-e-85 version) because the first one crapped out. I am switching to the Walbro 450 this winter. I say go 1450's on the injectors that way you have a little room to play with (1250's imo are gonna cut it close). My 1450's start and idle like stock.

Cool, does this require an adjustable FPR and rewire etc? Any instructions for setting this up? This would be my preferred option by far to avoid running a double pumper if I can... far less to go wrong.

 

My 400 didn't need a FPR I am not sure about the 450 though. No rewire for the power your wanting.

 

Ok, updated the first post quite a bit... lots of new things going on. The car is in the shop for the winter getting prepared for next years race season. Parts have been ordered and the car is going to be monstrous. I am fortunate enough to have been accepted as a sponsored driver for Agile Automotive Performance, and intend to represent them in the Real Time Attack Modified class next season. I'm touching base with the series organizers to verify the track locations and ruleset for 2013.

The updates to the car include forged Cosworth engine internals, an Exedy twin-plate ceramic clutch, Walbro 450 E85 pump, FIC 1450cc injectors, other fuel system upgrades, and an anti-surge cover for the BBK-Full. The goal will be ~500 awhp on E85 with maximum responsiveness.

 

These are really late, but the car is finally coming together. The motor is together now, and just waiting on the trans to get back, then it all goes back in the car for break-in. Here are some component pics of what went into the motor!

Agile Auto built 2.0L 4g63, Cosworth 86mm forged pistons/rods, Micropolished/balanced OEM crank, HeadGames port/polished head, Ferrea beehive springs, Ferrea titanium valves/retainers/guides, ACL bearings, AMS balance shaft delete

 

I heard Real Time Attack is no longer around?
