Thanks - should I look at an injector upgrade as well, or not bother? Best we have here is 94 and it's rare. 91 is mostly what we have all around here and it's 10% ethanol for the most part.
Whipple 4.0?

The 4.0L can be tuned down to match the fuel system. I think a third, external fuel pump would have solved my problems early-on... but I was expecting to do more mods down the road so my fuel system upgrade was more extensive than necessary... i.e.: don't be afraid of the 4.0L as an option. Just an FYI: I may be wrong but I think any 800+ hp numbers are going to be on 'special' fuel. BAP didn't help much IMHO but, as stated, I may have been dealing with a pinched fuel line inside of the tank.
As for long term usage, I think the stress on the crank, specifically the single keyway design, is amplified by 3.4L just as much as the 4.0L. However, when I dissected my motor and inspected the keyway there was almost zero wear on this item. I expected to see the keyway teetering on the edge of failure and it looked as tho it was barely broken in. My car had 33,000 miles on it (20k of which were executed with a 4.0L Whipple on the motor). Much of the failure is overplayed as the problems are expressed online, while the success (non-failures) go untold.
Get the 4.0L, and scare yourself silly.

There's no question now, I'm going with a 4.0L. I won't be nailing the pedal all day long and I feel that this motor is far more bulletproof than my 427 Z06.

Do you happen to have a picture of an installed unit?
Is 800 RWHP the magic number where you need to add the BAP?
I guess I am really asking if there is any chance it would be necessary at say 750rwhp?

Waldo,
Very nice torque line... solid pull from.. 2500 to 5500.. must feel like a CAT shot.
Looking at your A/F line , 5800 rpm is where your stock fuel system(?) starts to lose capacity compared to the 4.0 Whipple.
Do you have a BAP installed?

I have some great photos but I am in Vegas looking for EP at the Wynn :lol
When I get home I can post some. I found a great location that is more easily serviced if needed compared to where it is typically installed. A am also going to mod the tune file so that the voltage table is closer to reality with the BAP and jack the fule pressure up when the engine is under load. Torrie does that with good results.

Installing a BAP has been on my "to do" list since Torrie tuned my GT. I swear I will actually get around to installing one in the next couple of months. I just have to get all of these moving boxes out of the house.
