the 383 that mastertomos is referring to is my engine and the miniram def does make more power. like already stated, the price is the killer. Out of the 3 intakes tested on this motor (edelbrock, gm ported lt4, and miniram) the miniram made the most power with tpis's 58mm tb at 555hp. then the lt4 and then the edelbrock with my holley 58mm tb made just shy of 530. Super knowledgable guys and great customer service. Would recommend them to anyone. Id post up dyno #'s for throughout rpm range for torque/hp but sheets are in the garage.

Just kinda curious, what cam did you run with that setup?

That's interesting.
So the thing made 530 hp at the crank with AFR 195's and the XFI292 and 11-12 CR. Do you know if the heads are the new Eliminator style? (would have come out in 2009 I think).
Reason I ask is b/c I'm running the XFI280 in my 383 with AFR 210's. I've got a bit less compression than you (1/2 point) and a factory/ported LT4 intake. If your mill made 530hp at the crank I've always thought/hoped mine would be upwards of 500.
Will see how much that translates into on a chassis dyno through a stalled auto.
Sorry, didn't mean to usurp this thread. I agree with a few that I like the stock look of our motors and wouldn't change that unless I could keep a factory looking intake. But the price of this TPIS intake is outrageous :O

o well maybe someday. let me know how it turns out. Back to the whole intake thing, if someone comes up with a better flowing intake than the miniram i'd def be interested eventually. It sucks u actually have to buy a different fuel rail for it! otherwise it wouldn't be so bad.

I'd really like to see someone do the TPIS. Most people are happy with the power the Stock ported intake makes and that's understandable once the bang for the buck is considered. I'd personally love to see what a ported TPIS Miniram would do on a healthy LTX.

Same. I have an LE ported LT4 intake on my 385 with AFR 210 Comp Eliminators, but would like to see if there is more to gain with the MiniRam or HSR?

Agree, for those of us who are 383ci+, big cam (240+ duration/.600+ lift), high flowing aftermarket heads, I think would benefit from more than a ported stock intake, this would be a good intake dyno test to do. The price isn’t much different from a single plane conversion.
