I've read at the Silverado SS boards that the TBSS intake gives the same gains as an LS6 intake (15-20 rwhp) without losing any TQ. If this is true I've found one with everything except the TB for $200 and it's brand new. Have any of you guys done this swap or know if this is true.

If it will work I'm going to add it to my pile for installation once I gather up everything I want to install. Before this goes on I'm going to have headers, Cam (TSP Torquer v.2) 918s and Aluminum roller rockers. Then when I get ready to install all this I'm going to port my heads (myself) and have a custom dual exhaust with X pipe dropped in. Hopefully this will get me deep in the 13s NA then deep in the 12s and possibly high 11s on 100-150 shot. I don't want to back track anywhere on my way and I don't want to spend a ton of money (who does).

If this would be better in the GIII forum feel free to move it.

 

That is most likely a true, but the TBSS is designed for low and mid RPM range. But once you get above the 5000-5500 RPM Range, that is where the LS6 intake will then take over and keep producting HP and TQ.

so, depnding on what RPM Range you expect to run and drive your Car/Truck.. and with what you have said, you might be better off with spending the extra cash for a LS6 intake.

 

I'm getting some good information all around on this whole subject and I'm thinking you're right about the LS6 intake. The cam I'm looking at works from 1800-6400rpms and with this big heavy truck I don't want to give up any TQ.

 

The Car Intakes will perform way better up top, almost a 1000RPM's more, but you will have to change around all your Acessories to put a Car Intake on.

I assume you are talking about the Truck LS2 Intake though.. that is supposed to be pretty good.

 

Yeah I'm talking about the one from the Trailblazer SS.

 

What about the LS2 intake from say a GTO or Corvette? (for an LQ4 or LQ9 going into a car application with a cam swap, IE TR224..)...

Ive read about people saying that they arent worth the install...any truth?
I mean I see used LS6 intakes go for $300-$400...and used LS2 intakes going for $150...Why?

 

I'm interested in the answer to that myself. I know on the Silverado SS boards they said the TBSS LS2 intake was good for the exact same HP gains on the LQ9 as the LS6 but with no loss of TQ.

 

The LS6 will out-flow the LS2 Car Intake, it's been proven, that is why they are more.

You have to change out all the Acessories and Brackets on the Truck Engine to run a Car Intake.

 

Now what if someone takes an LS2 (car intake from Corvette or GTO), does a little hand porting to it themselves...any benefit now over the LS6??

What areas does the LS2 car intake lack in, in its stock form? bottom-end to mid range? or mid-range to top end??

 

The LS6 pulls harder in the top-end. I'm still trying to figure that one out as well, but it just does.

 

Just from dyno charts Ive seen that were LS2 to fast and LS6 to fast the difference is the LS2 mani just doesn,t flow up top like a LS6 or fast. I wouldn, even bother with a ported LS2, I would just get a good ported fast.

 

This has been discussed over at performance trucks. Truck LS2 will give you gains over the stock Lq9 and will swap the easiest and will have have slightly better torque down low. LS2 car intake gives a pretty good bump in top end without much sacrifice down low. LS6 will probably have the best top end.
