422 or not to 422, that is the question

Guys I need your help. I am selling my truck so I will have some money to put into my fbody. Currently I have a procharger F1 blower on the car with a T1 cam, FLP headers, 12bolt, and all the other bolt-on crap. I am think of selling my procharger kit and getting an ARE 422 and spraying a 200shot on it. Do you guys think I should do this or should I put some good pistons and rods in my 346 and leave the blower on it? BTW my 346 is making 550rwhp now on 10psi. I know that a big cubic in. motor and nitrous is the most proven way to get our cars into the 9's but, the sound of a blower is music to my ears. ALso this is my daily driver. Any help at all would be great.
thanks
-Jasen

If you go with the 422, you'll end up with about 500-550rwhp without n20, which is less than what you're making right now.

There are a guy on corvetteforum that is making 630rwhp with a D1SC on a stock bottom end.

As for bragging rights, you can brag about how your supercharged 346 will leave a 422 in the dust!

build the 346 with boost, better cam and some ported heads, drop the CR to 9:1, and tune it, I think high 570-600 rwhp on pump gas is very attainable. the all motor setup will cost you a arm and a leg!

Re: 422 or not to 422, that is the question

422 built from a C5R block. LS6 heads, and a "relatively" mild cam.

Maintanence would probably be a breeze on top of it all..

but if your current setup works, why bother with it?

Re: 422 or not to 422, that is the question

Is it just me or is it my imagination.

500 RWHP N/A seems to beat (pretty handily) 600 RWHP FI cars.

N/A seems to be better than FI. I mean this on an "overall" basis to.

What gives?

SuperSport2000,
Go with an ARE 436 N/A, 500+ N/A RWHP. Mine goes in in a couple weeks and with Wade running things over there now, you're set!

Re: 422 or not to 422, that is the question

Here's a different opinion:

I looked at the forced induction versus big motor/N2O route, and (obviously) settled on the gassed big motor route. Why?

1) Forced induction is a pain in the butt to tune - you will be fiddling with it a lot.
2) It can shorten the longevity of your engine given that it is always on. Then there is that issue of the crappy head bolt arrangement of LS1/6 heads, a problem for large amounts of boost.
3) Bad gas mileage in a daily driver.

On the flip side,
1) You do have to refill N2O bottles.
2) Don't ever go lean on N2O.
3) Don't ever spray at the wrong RPMs.

The advantages of the setups - on boost, you always have the power, and can make big power easily. You also get that nice sound of the impeller turbine to intimidate the competition. With N2O, you can have mind-numbing torque easily, better daily driver, and LS1s seem to love the squeeze.

Overall, it's close, but I think I would take the gassed 422 (as I have) in a squeaker. Other people have differing opinions. You might also want to PM Currdog (Sean), since he has both a gassed 422 setup and a twin-turbo 346.

For example:
y2khawk --------- 10.97 @ 127.17 [1.69] --- ITT-10 SI M6 RR342 WT4000 TH 573x615@MI

Colonel: 9.90's with less power and torque and almost a FULL second in the 1/4.

One also has to consider the average torque applied during a pass, turbo lag, and similar issues. I admit that I have been disappointed with the performance numbers I have seen at the strip from turbo LS1s. It seems to me (not sure if true) that turbo LS1s do not have the dragstrip performance you would expect from the power/torque numbers.

Re: 422 or not to 422, that is the question

I also see other types of cars like Supras that have 700-1000 RWHP and 1100+ RWTQ and some are in the 11's, some in the 10's, but with that power they should be in the low 9's.

I just cringe at what a LS1 solid roller super stroker with an an aftermarket intake with 600+ N/A RWHP would do at the strip.

I would go solid roller MTI 422 with nitrous.Their cars seem to put out better numbers at least from what I have seen on this site.Not knocking ARE at all its just if your spending money then get the most power that you can out of the money.

Re: 422 or not to 422, that is the question

WoW!!!!!! thanks for all the replies guys. I didn't think anyone would reply. As far as the best setup it seems NA with the bottle is the way to go. I would love to have big cube motor and my blower but I can't afford it. Now the idea of a Big cube solid roller motor sounds good but my car is a daily driver.

Re: 422 or not to 422, that is the question

I'm going the same route as WeatherGuy. But instead of 422 aluminum, I chose 408 iron block. It will be built specifically for a big shot of nitrous with a secondary fuel system (to keep race gas in a separate fuel cell). <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
