Tony.
So, no on the sheet metal for my LT4 hot cam car?

I'm running the one on the right. The middle one's runners and injector angles were way off.

Top taken off mine.

Ive seen back to back test with an intake swap only from a ported LT1 intake to a Victor Jr and the car picked up around 80rwhp/tq everywhere from around 3600rpms+ on a YSI vortech car

I have heard about that type of gain a few times as well, but this guy had proof. Seems like the LSX guys see similiar gains as well.

Can you give us more details on the build? I'm researching a single plane setup and vic jr is on top of my list. I just wonder what all was done to the guys engine when he gained an extra 80hp.

well with ysi blower your going to pick up quite a bit of power cuz your probably running a large cubic inch motor with 15+psi. it makes sense, now on a bolt on or heads and cam motor isnt not going to be as sagnificant.(sp)

TPIS makes an aftermarket mini-ram intake and fuel rail, my buddy's 383 made 529hp on their engine dyno with the GM intake, and 555hp with the TPIS intake.

The #1 cylinder would get no air compared to the back cylinders. There was a recent thread in the dyno section where people were gaining 50+rwhp going from sharp radius elbows to an elbow with a real radius or 4150 tb.

If your going with a single plane might as well go with a 4 hole tb for the best distribution and flow.
