Naz intake write up

[Glenn]

Interesting analysis bcastro - more logical input of this kind is needed. The bottom line is save your money for a SC - sending money on a stock internal NA engine to push it over 300 HP is just not worth it. 290-300 HP is the resonable cost limit on a NA stock internal engine before going SC.

Glenn.

Agreed. Yes after 300rwhp (basic bolt on's and tune) a SC dollar for dollar is the way to go no matter how you slice and dice. Just the intake will not be worth doing alone. H/C/I + R&R?tune $4500+


Now if your in the situation I am in:

Built motor plus + SC of choice is $14/16k

or

Built NA (BB/Stroker/H/C/I) + RR/Tune for now and setup for FI later $11/12k

**all supporting mods hoping to be over 400rwhp+ I think this mod (intake) is worth doing because the amount of air that needs to feed the new beast.

I must say I went this route because 1. I wanted to have a unique setup BB/S 5.3L (Alternative Auto/Modular Performance articles) and save a few bucks 2. Not real confident on a SC install here in Cali (I have to smog this month!) although the Vortech Kit should work on a technicality.

Ok, I bit.......I am in the process of purchasing one of these. I spoke to Carlos and he is going to match the runner lengths based on the CR/CI of the new motor. He is also going to reinforce the bottom end to accept the blower (DR Vortech) in the future. I spoke to my builder and he was mentioning the intake will be a bottle neck with my setup and wont gain the full potential of the motor. I am also looking to get the PHP Intake spacer from ImpalaSlayer. My goal is to get at the very minimum 400rwhp and with the PSRI 450rwhp+ NA so here I am.

Not sure if your cam selection will rev high enough to take advantage of the short runner intake, may want to re-think that decision. Of course, if you optimize the cams for the setup they most likely won't be smog legal.

I believe in people doing their own thing and enjoying their MMs. So any advice from a SC guy to any NA guy is not going to appreciated. So at the risk of being flamed . I'll just say one thing.

Spending $12,000 on a 400 HP NA engine and then being blown away by a 400 HP $6,000 Trilogy SC on a stock engine would make me very unhappy. SC your engine and enjoy it until it blows - $6,000. It may last a lot longer then you think. Plus, your 400 HP NA engine will not be as streetable as a Trilogy or even a Vortec engine. Lastly your HP will be made way too high to be much use except for high speed runs. A 400 HP SC engine will beat a 400 HP NA any day because it will get off the line quickly and 90% of a race is the launch and first 60'.

OK, go to it

I laugh at your posts, I truly enjoy them. I agree with 99% of it. The whole point of the NA 12second MM was to see if it could be done. Had nothing to do with value/hp/cost, etc.

Thats my dilemma. The ported short runner intake with this cam will "still" make power not optimal but there are trade offs living in Cali. The GT Cams will make peak power at 6500 and the PSRI will broaden that see linky (hopefully).

Glenn, nice to hear you chime in. While you may be right about 400NA vs 400SC.....I still have MORE POTENTIAL. The motor is built to make HP NA while still be able to accept a power adder later. And the reason I chose the cams I did was not only to pass smog but still be "streetable". 850rwhp is what the engine is rated for. Now you have to remember why I am where I am.....rod knock at 115k.....Not wanting a run of the mill built 4.6, cobra reman, or even an Alluminator, why not be unique and setup the motor for a SC When its all said and done I don't think anyone on the West Coast would have this combo in a Marauder.

BTW, the motor itself is costing me $7167.95 before tax and shipping.
