Turbo BB?

[SwedCharger67]

Any idea of power increase with E85 over conventional fuel? ...

Strictly looking at the fuel physical data you should gain somewhere from 11% to 27%.
Seems that most non-boosted engines see a 10-15% increase in power, assuming the AFR is correct.

Thanks! How do you like E85?

What would you recommend for the camshaft department? I know the old wise tale of "112-114LSA" for boost, but have read many stories of racers running radical N/A cams creating heavy overlap with great results with Turbo's. I'm kind of lost between the lines, as I know people who build insane power with factory cams in LSx builds and others who use very radical, turbo specific camshafts and build far less.. Some turbo cam companies state you want an 108LSA and huge amounts of duration, another states low duration and wide LSA. What is your insight on this subject? What is your opinion on timing with a turbo build, is a boost retard box necessary if running low amounts of initial timing on E85. I know the car cranked real easy on 20*, but was over 40* with the factory curve at full advance. We just locked it currently at 34*. I just don't want to rely on a controller, and it end up going out as I have had 3-4 ignition box's go out over the past few years (mallory/msd), and toasting the motor when under boost. I would rather it be a little lousy down low and be great up top. If E85 can give me this ability, then that is another plus. It isn't all about saving a buck! If it is completely necessary, then I have no issue with purchasing one.

What are the specs now you're running ?

I have built some turbo motors that range from big hp everyday street use to one of the fastest outlaw cars, believe it or not the outlaw cars run pretty much the same exact cam i have in my street car.
Some of the bigger hp street cars are a little different from each other depending on the rest of the motor. Most are all normal cams to me in 110 108 area, lift 500's and duration can be as little as 228 to 290 , again all depending on motor size.

Current specs are .590/272* dur @. 050 with 106LSA.

Okay, bad news..

Ebay wasn't good to me, got up early in the AM for the final few minutes of my bidding but was sadly outbid in the last thirty seconds by two individuals who clearly wanted it much more than me. This was for the killer E85 carb setup.

Okay, new idea..
Single S475 or twin GT45 (ebay) turbos. Their is a 30+ page review on these on theturboforums.com and nearly 99% have been positive. I can have both turbo's for around $500 or a single S475 for $640. The GT45's have a one year warranty as well. They are 70mm/1.05ar each. S475 is 75mm/1.32ar.

Okay, car runs on pump fuel at 34* timing right now. Any idea if I could run 20* total locked and run pump with 10-12psi? Engine only has 10.25:1 compression. Trying to still get the carb situation now figured out. I'm thinking I can scrounge up and actually have twin GT 45's for $500 and the flanges, clamps, etc. for another $150 possibly. Not one single issue on theturboforums.com on these cheap turbo's and their are some 800+rwhp builds with twins and 8 second E/T's.

Racingjunk has a few blowthru's listed spelled many ways. If you just scroll thru the carb section you'll run into them. Here's one that looked interesting http://www.racingjunk.com/Carburetors/182005334/csu-blow-thur-850-carb.html

Thank you, I actually was looking at that earlier today..

I just made some major purchases, $1,200 worth for parts off of yellowbullet.com from a guy.

S475 borg warner turbo from forced inductions, with oil fittings, v-clamps, couplers, etc. Also K/N 5" filter.
CSU 750 blow through carb with Aeromotive FPR.

The turbo is a T/6 with a 1.10ar. I felt this would be better for spooling with a 4-speed than the 1.32 version. If it doesn't work out, I can always trade or sell.
