It is very good, picked up some solid gains across the curve from just the TB alone. I have not put the car back on the dyno after adding the Roto-Fab and probably will not until it is ready to be tuned. With that being said, it certainly did pick up, the blower whine is more pronounced, and the combination is noticeably more responsive.

Did the topic of fuel pumps come up? From what I've read people seem to think that may be a week point after all bolt ons are done. Wondering if there is any concern with the cam, etc you plan on doing.

Pretty sure OP is doing the classic underestimating of hp numbers so he doesnt have room for disappointment when the numbers get laid down on the dyno lol. I do the same, i rather be surprised it made more than what i thought vs being disappointed it made less

Meth + E85 is actually very common and still gains to be had. E85 isn't going to do anything to IATs only when the combustion happens will it cool the burn.

I completely agree that there wiil be substantial gains to be had with meth, I just don't want to run it due to my intended usage or the car. Now, if the meth kit talked to the ecu, or could switch back to a 93 map on its own like flex fuel sensor, then I would be on that plan. Just not going to depend on something that I really have to have in order to be safe when there is a very good chance that I may not be able to find it.

And I very well may run out of fuel, but I will cross that road when/if it comes up. I know Lingenfelter has their new pump out, but $1500 for a 10% increase is pretty steep....

Looks like a great build. I am considering a TSP stage 2 vs BTR NA/SC cam. One item that concerns me with these cams is the fuel lobes requiring a lash cap. I have read of problems with lash caps coming loose. I know TSP has two fuel lobe options, one is 32% (requires lash cap) and the other is +10% which I do not believe needs a lash cap. BTRs cam is +38%. Anyway, I am not anticipating your planned power levels being an NA build, so the more aggressive fuel lobe may not be needed in my 1LE. Did TSP recommend any specific lube for installing your cam?

Nice setup! Make sure you share a dyno video and start up plus idle! Can't wait to hear the lope!

[USP45]

I am a little bit leery of the lash cap myself, but I know that I'll need that extra fuel with where I am heading and yes, they did recommend it. I am hoping that with a little bit of time we will see the price of fueling options come down. I guess if you are one of the only games in town that you can charge whatever you want, but that Lingenfelter pump is pretty damn steep...

so the vvt cam works in a non vvt lt4?

[djfury05]

I'm debating 1 7/8" or 2" ARH long set up. Goal is 700-750rwhp on stock heads/cam with focus on area under the curve. My gut says 1 7/8" for more torque but there's not much data yet. What made you go with 2" ?

If I had to do it over again, I'd go with 1 7/8. I went with 2" with the thought of continue to build it up. I have since reconsidered. I have just had "TO MANY" stupid issues. From manufacturing problems to incompetent PPL working on it.

700... maybe with meth, e85, pulleys,cai, and a tune. But 750 at the wheels is gonna require a cam... unless u swap out the blower.

The LT4 does have VVT, but no AFM on the ZL1's be it auto or standard trans.

I went with 2" just for possible future upgrades. I know that I may loose a little on the bottom right now as compared to 1-7/8" but the bottom is so stout as is I am not worried about it. Heck, I cannot hook as it is right now...

That's the plan.. And add ported blower, snout and throttle body. I hope to have it all ported as a package by Tony Mamo but he said his program for the LT4 is awhile out yet.
