Well, how about this?

Since we all are in the search for an optimal package...

What if a big cam is matched, since hey are know to have a "weak low end" with a roots style blower on a 114 or 115, maybe even a 116 lsa? I'm talking along the lines of a cam like 237/242 or 240/244 .6xx/.6xx...

Is this a logical and functional theory or has it been done before and "that was that."

I know that, and im with this group, that a roots blower is the least efficient of the FI family and that it "eats" up more power produced than any other form of FI. But can a package be optimized to achieve let say, over 600rwhp or 700rwhp with a heads, cam, 370 shortblock, and a magnacharger?

 

So this is not a T- Trim. Its a JT-TRIM correct? But you put it on a T-Ttrim bracket? Please let me know. Ill change my order monday and pay for the JT Have to make sure they offer it in the rotation I need.

 

You've got the idea... although good luck getting much over 500rwhp with the maggie. It is just too small to provide the needed CFM.

This principle is why a lot of people with big ol' engines like a 427 go with a centrifugal blower... engine takes care of bottom end, blower takes care of top. A lot of times going turbo with a setup that big causes to much midrange torque, creating horrid traction problems. I think a 346 w/ a KB or whipple with a giant cam would be fun power everywhere.

 

Here's the dyno graph:



Is that showing a lot of pulley slip or is something else causing the boostline to fluctuate like that? If the boostline is valid, why don't we see any effect on the dyno chart, or does it happen too quickly? According to the boostline, this run spent the majority of time under 5# of boost.

Question how does duration affect boost? Befor I get bashed for not using search I did . Plus I read the cam sticky and the turbo faq. Somebody break it down for me no opinions just facts thanks

And I cant spell!!!!
