Right now I have new heads, a big mouth intake, exhaust, cam, custom tune, slight airbox mods, and various other little things.
Who has used the large tube runners (or another version/ make) and what can you tell me about them? I read that TPI shootout article and saw the peak hp and tq differences between all of the setups, but that doesn't always tell you everything.
I would like a HSR or MR but I need it to be CA legal... or at least hidden enough so that it doesn't matter. So my options are either the larger tubes, or the ASR.
I already have a big mouth manifold, so I'm just 400 (or is it 500?) bucks away from the large tube/ big mouth setup. How good is this combo? How good is it compared to the ASR? The ASR seems to be the least favorite out of the MR and the HSR so it would be nice to hear some feedback.
Thanks.

What do you mean by ASR? Arizona Speed and Marine runners? They are the best factory compatible runners you can get, but they cost a pretty penny. Too bad you can't run a HSR, most cost effective intake out there aside from converting a LT1 intake.
They double as a weight loss mod too.
I had them on my old engine before I went stealthram.

By ASR I mean Accel Super Ram. I would love to run a HSR... and I still might... but I really don't want to possibly be forced to swap it out every two years.
From what I read, the TPIS (Large Tube Runners) runners are made by Arizona Speed and Marine... is that true?
One thing I liked about that TPI shootout was the amount of torque the runners + big mouth put out... I love to feel me some torque but I want top end too... I just don't want to waste money you know?

Have you considered a First intake? Its like TPI, but MUCH better.
Yes, the TPIS runners are the same as the AS&M runners.

Thanks for taking the time to help. It's much appreciated.
I haven't really found too much information about First intakes. Is it just like another HSR but with another design or is there more to it? Looks like the cost is about the same... Has anyone put one on the dyno and compared it to some of the others?

Its a TPI on steroids. Massive runners, massive ports. If you want a traditional LTR type tpi system its better than any TPI out there.
The HSR is about equal to a built TPI system, it just has its power in a slightly different place. HSR shines through by losing a minimal amount of torque in the low range, but gaining a massive boost in the top end with a mild peak increase. So you can run more gear.
This is essentiall the old electromotive TPI setup. Nothing is compatible with the factory TPI system.
GM TPI runner vs First Runner. GM TPI = 1.48" ID, First = I think 2" ID.
No use rehashing all of the First TPI info though, just do a forum search for it. Tons of reviews, some old magazine articles showing dyno graphs, and lots of info.
First TPI with a vortec base and vortec heads on a mild cam = easy 300rwhp with over 400lb/ft.
