That would be a stand alone fuel cell. It's aluminum with an in tank pump and external regulator. I'll use it to hold really high octane fuel if/when I add nitrous so I don't have to pull anymore timing than when I am boost only.

 

So that would feed the nitrous solenoid only? So in theory you wouldnt have to mess with your tune when you hit the nitrous?

 

Correct. I tune it to be a fairly aggressive tune boost only and kill mode is an "on" switch and WOT away from another 200 horsepower. C16 in the cell would get it done.

 

So in thinking through my next steps there are a few things on my mind. I want to stick to a blower. I like the instant power. Even a procharger is snappy compared to a turbo which almost gives up all 'snap' for what is almost endless roll on power.

First, obviously, its gotta be good for big power. Not like 90mm turbo power... but big power. Power that could take me mid 10's at 5300#. To that end I think I have narrowed it down to 2 options.

The TVS2650 or a procharger F1A-94.

The TVS delivers what I like in a power adder hands down. Question is can it deliver enough? The blower swap would involve another cam swap to allow the larger compressor to do its thing without choking. I would likely limit it to 18PSI or so seeing as these things don't love high boost. The cam would really let it breathe... so 18psi is a hell of a lot more air than most are flowing with a 370.

The procharger has a better chance of delivering what I want on the top end. This would also require a cam swap, and I would be torn between a factory 87mm truck intake and a holley high ram. Odds are I would go high ram. Max boost would probably be about 20psi. My fear here is to get a converter that makes this combo sing it would have to be pretty loose... in my truck at its current weight with AWD a loose converter blows. It would also very likely be wildly inefficient up top. Hell even my PT2800 drove loose with the 1900. Looser than most of you with a 245mm 3600 with a single cab 2wd to put it in perspective. Another downside is the noise.. that BOV with a big procharger is loud as hell. Obnoxious almost for a street vehicle. Thats what this is and what it always will be. Its a street truck I take to the track from time to time just to proove its fast lol.

With either combo shift points will likely be about 6800.

Not much to say beyond that... just figured I would open it up to discussion and see what people think.

 

IMO you're dead set on a PD blower and don't want anything else by the way you wrote that last post.

Why not try one of those massive whipples? Like a 4.0 or something?

 

Whipple?

You'll be pioneering the tvs2650 on the LS platform, that's something worthwhile imo

 

I've never seen a big whipple on any GM pickup, so if pioneering was your goal that would be another avenue to try.

 

Thats because the big whipples are hard to fit in a truck without major modification. I think a couple guys have used the 3.4... but i have never heard anything about it. The 4.0 just taked too much work to make it fit.

The new 4.5 on the other hand... that bad boy could work. It's made for the LS platform with a front inlet. We will see.
