Whipple crew get in here!!!
Ok, so i am not going to retype my whole original thread(will take forever).
Please read through this so you will have a understanding of what i am going to talk about.

Thanks!
Anyway, what i need to know is what are the guys with the 3.4l whipple running it at psi wise? are you running race gas? when is the blower the most effiecient? i heard that it doesnt really start making good power unless you are spinning the **** out of it?
any info on this blower would be greatly app as you guys are pretty much the only ppl who run the 3.4l whipple
Thanks!

I have the 3.4L whipple...
I am running the stock pulley on it (3.5) with the stock lower, and I am making a tad over 23 lbs of boost...
On a conservative tune (12 degrees of timing and 10.6 afr) I am able to run pump gas, with ZERO knock (ping)... The blower is INCREDIBLE efficient. At 70 degrees ambient, IAT'S were mid 90's. I am running a built engine, 5.1L stroker, ported heads, and cams. On a stock engine, boost with the same pulley would probably around 25 psi...
A lot of the Cobra guys running the 3.4 whipple on stock cobra engines, are putting SMALLER lowers, to reduce the boost. Some all the way down to 18 psi. At 18 psi, the 3.4 really doesn't make any more power than the 2.3 does. The blower likes to spin fast, and that is where it really excels...
As for bolting on the the 3.4L Whipple, it is just like any other twin screw. Only extra thing is that my hood needed to be notched very slightly to fit it. Also, it REQUIRES after market fuel rails... Everything else is direct bolt on...

this (if i decide to do it) will be going on a built engine although not bored out. still a 4.6l. so at 18psi, the blower is just entering the lower efficiency range. What kind of numbers are they laying down? why not go to 19 or 20 psi? why do they install the smaller lower to lower the boost?
keep in mind this is a 2v.... dont know if you read the previous thread or not.

The 3.4L Whipple is huge... If you understand how positive displacement blowers work, you should understand why the lowest boost numbers from the Monster Whipple are so high... 12 psi from a 3.4L Whipple? HAHAHA! Maybe if you try running a custom 5 inch pulley, lmao! But at that range, it is spinning way too slow...
25 psi is too much for pump gas, hence the reason the stock 4.6 cobra guys are getting smaller lowers, to run lower boost.

what is the max psi the 4v guys are running before having to go to race gas? and you never did say what they are laying down(hp/tq) at 18 or so psi.

that thing is effen H..U..G..E

Unless you're running over 22psi . Then don't install the 3.4 These things work best over that number . The 2.3's are great up to 22psi . Then run out of efficiency after that . That's what I have been told .And that's why I chose the 2.3 . I don't want to run race gas and won't be winding the **** out of my system anyway . If you want the WOW factor . The 3.4 will do it for you . Either one will require you to replace your factory GT hood . As I did with the 2.3 . You can lower the engine . But with headers and deep oil pans I wouldn't recommend that route .
