Intake for ls1 ta
Intake for ls1 ta Im trying to determine what intake to go with on my build. Stock bottom end lq4. Ported polished 243s torquer 2 cam. 3600 stall. I am going to be spraying it with a 175 I have a lead on a spuer vick with an elbow and a lead one one with a 4150 accufab and a nitrous outlet puck system. I like the accufab but i noticed that water gets on top of the motor when it rains and it makes me worry with a 4150 being able to let water bypass it. I do not have a garage or covered parking for the car. Didnt want to go with a fast as they are a pretty penny. I also looked at the btr intake comong out but it looks like that intake will perform where i do not plan on pushing to.

The BBK flows about as well as the LS6. Most NA apps don't use it as it does run warmer than a plastic intake. Turbo or supercharged apps like it as it won't burst under pressure. That is its only real advantage.
Like mentioned above. With the BBK being aluminum there is more possibility with porting and port matching to the cylinder head. A skilled Porter could probably make the BBK really shine. Seems lime a good choice for forced induction.
The Super Vic definitely got a lot of potential based on air flow, probably will need some porting to get the most out of it. Likewise, with the 4150.
Ideal cam selection with the Super Vic & 4150 may have a narrower LSA than the typical long runner LS manifold.

Brian Tooley is coming out with a new one for cathedral ports. Looks pretty interesting and supposedly fits under the 4th gen cowl without cutting. Website says they start shipping in December. Kinda cool there are new parts still being developed for these cars.

With that being said, Im pretty happy with my Fast 90.

Using nos, go with an aluminum intake. They heat soak a little more vs plastic, but are stronger if your nos system backfires. I've seen plastic intakes explode off a c5 using a 78mm fast when they came out over a decade ago!
My issue with an aluminium one is if I use it with an elbow I am basically along the lines of a fast. I would need it with a 4150 throttle body but since I do not have a garage when it would rain, water would get into the motor. Noticed it when I was in the rebuild process that my engine was getting water pooling on top of the motor after a rain.
The btr intake is what I originally had wanted but it loses power and torque down low and I would not be spinning my motor hard enough to utilize the intake at all. I was really let down as that is the one I wanted.

The way it reads, it sounds like he doesn't have a hood, and with a 4150-type intake manifold, it is literally raining into his engine. Sounds stupid, I know, but that's how it looks.
I noticed that water was getting through the cowl area onto the top of the motor. car has and will always have a hood Not sure how any other way the water could get onto the top of the engine unless its coming through the cowl area.

If your car is a Gen4 Fbody, the intake is pretty close to the cowl. Any water running in off the hood would run down close to the intake and possibly into the throttle body. Do you run an air cleaner?
Car has an ls6 intake on it and has a filter. my issue would be if i went to an aluminum intake. I would have to run an elbow on it and from i have seen that makes them not as efficient. with the 4150 there is no room for a filter plus i still take the chance of water running down into the motor.
