AHDDM, do you mean 400rwhp without power adders or just without FI?

A solid well tuned shot of nitrous oxide would yield 400-plus. A lot of guys are running a 75hp shot of n2o without even retuning. Proper tuning and some well thought out bolt-ons would get you there and then some quite comfortably.

I honestly wanna stay away from nos as much as I can. But power adders are ok, and I guess stroker are ok too. No FI, no nos

There is a guy with livernois stage 2 heads, comp stage 2 cams and JPC intake manifold. He put down 409.

Totally fair wanting to avoid n2o, it has had some pretty rough press over the years. Bullet riddled cars exploding in giant blue fireballs and all! Nitrous has a terrible stigma, but from what research I've done; nitrous oxide isn't bad. In fact for the 3V s197 it can be a safe/cost-effective way to pick up HP.

yes.. didn't JDM get 11.3 1/4 mile with a stock (not stroked) engine with those heads, cams, and full bolt ons? unless you just care about dyno numbers I think that is superb performance for an N/A 4.6L engine.. Still costs more than throwing on a $3800 Vortech to get 400rwhp w/o any other mods.. but always cool to build something different.

Yes.. N20 can be safe but I see it as more of a cheat than F/I.. because you don't always have that power available, low bottle or something else causes you to not be able to use it.. I still consider it riskier too, not if it's setup and used properly, but still has risks to it than a s/c at lower boost levels.

That's the direction I was thinking of going. In terms of the stress put on the engine internals the cams and ported heads would put much less stress than a S/C correct?

ahddm

LMAOOOO at exploding car. No that's not why I jus like knowing all my power is there when I punch it. Plus I dont want another tank to fill -_-

Anyone/Everyone: how's the drivability on those giant engine builds? I've never pushed one through its paces, but I've been in a few with some wicked cams. It gets to a point where "street-ability" becomes an issue. They sound and move out like a raped ape, but I'd never want one for my daily commute.

AHDDM: Mishri is onto something there: what's your goal? Do you want that magic four-hundo HP mark, or do you want screaming track times?



Oh, and Mishri, I'm right there with you, n2o definitely has an edge of cheating to it. But I can't justify the price tag for FI. I'd love nothing more than to push a dozen atmospheres of pressure through my pony, but with my ratio of WOT time to time spent screaming at my windshield in rush hour commute doesn't really make sense to go forced. But for a complete (edit: very thorough) set-up under a grand I might be able to con the practical side of my brain into letting me drop a bottle in the trunk.

ahddm

Mostly cause I can Jus want to push the engine as far I can. Theres no reason I wouldn't want an SC I love the whine. Plus the guy at the dealer said it's impossible so I took that to heart :-p

Mishri

I think the solution for you is the Vortech v3.. depending on what kit you get from 3300-3800 (400rwhp from the $3800 kit im thinking of).

most complete kits ive seen with bottle opener, warmer, pressure gauge, blow down kit (for tracks), maybe a purge and a tune you could be up to $2000.. But you can probably find one cheaper, especially a used kit... then you have bottle fills.. eventually will cost you nearly as much as the S/C... so.. tough call I guess if you dont plan on using it much the refills wont cost you so much.


oh.. and that 11.3 time apparently was with a stroker.. 298.
