Anyone have an idea how this can be done. I just ordered my 422 from mti and was going to just throw a 150 wet shot on in. But I would love to see it be all time power with a turbo or blower. Anyone let me know on a set up that would work with it...

 

Sure it would work. Probably would require a hell of a lot of tuning, and cost you a hell of a lot of money! It would make insane power, I would say upwards of 800 hp and over 800 tq. You'll be able to inihilate the tires at 100 mph <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

 

o but how? and are u talking about like 6k or 10k?

 

I'm trying to continue to scarf up the money for a Golden West Performance 422 Iron Block built for boost. Try closer to the $teens$! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

I don't know that they've settled on a final production price yet, though.

 

Why not ask Jayson at MTI? I am sure he can answer that question for you. UMM VERY NICE THOUGH

mti actually told me to spray the motor. They specificly said not to put a blower on it and said they themselves won't even do the work..Christopher I talked to

 

One of the big places that does large stroker/borer motors took a kit to GWP to do the blower part. It is a pain in the butt. Getting the right combo in the motor with the Big Cubes to then make a significant HP gain over that with the blower seems to take some work.

You gain HP/TQ with the Big Cubes, and it seems like you would have that much more of a monster with the boost. But, the bigger motor demands more air, too. The RWTQ is crazy-wild and getting the RWHP to equal out... well... it's going to be an interesting summer/fall/winter. What's left of the summer...

There is no reason that a 42x motor can not be blown. I know a guy here in Denver that is running a ARE 427 with an ATI F2 on. Previously he had the F1 on it and it made about 690+ rwhp <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I am not sure where he is at with the F2 project.

I think MTI may have refused to do the work and said no blower because they already built you a high compression motor. If you want a blower or turbo you should get new lower compression pistons.

It's alot cheaper to figure out what you want first before you pay or have it built. (believe that.)

If you had gone with the lower compression motor right of the bat, a blower or turbo would be a nice combo, and I think MTI would not have a problem with it.

The only "artificial aspiration" I would run on your motor is nitrous.(I imagine it has high compression)
Unless you don't mind having the motor done over with lower compression(pistons)

 

I love forced induction, and looked pretty hard into the blow versus spray issue on my 422. As things are now in LS1 world, I definitely side with the spray. Why?

Blower/turbo issues:

1) Finding one that can *reliably* feed a 422 is a serious challenge right now, outside of a good custom unit. Some people have succefully done it, but it has required major custom work thus far.
2) Tuning. Enough said - the issues can be brutal with the big cubed motor.
3) Reliability. Until there is a reliable and mass-produced unit out there for the bigger cubed motors, this is going to be a challenge.
4) Heat - well, at least this matters in Texas. Running 10 lbs of boost on a 422 on a 90 degree day = 235+ inlet temps. Better get a big intercooler.
5) The aluminum heads on LS1s do not seem to like high boost. There have been reported problems of heads warping.
6) Expect about 5-6 MPG tops if running serious boost on a big cubed motor - (have supporting data on this)
6) Summing it up, we do not have reliable units out *yet* outside of good custom work. The data are still pending on some of the new units.
7) And of course the advantage - potentially huge and continuous power if you could get the setup to work well. And you could be the fastest street car in your town.

Gas issues
1) Gas can be dangerous. Too lean, hit limiter, or spray at too low RPM = big boom.
2) Occasional need to refill the bottle.
3) Not on all of the time.
4) Summed up - the usual gas issues.
5) Big advantage - LS1's *love* being sprayed and can pick up serious power easily.
6) Spraying is not weather sensitive.

I still like the FI route, and want to go that way in the future. But for right now, I will be spraying for the near future. Want to keep 20+ MPG highway but still have 700 RWHP and 750+ RWTQ for the track (or for anyone wanting to pick on me on the highway).

 

turbo would rock. You could get Robs kit with a t-76. I dunno how you are going to get traction but it would rock.

 

What the ball park $$ figure for a 422 now??

Sounds fun <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

They can also sleeve and do an Iron Block 427... about $1500 more. <img border="0" alt="[whiner]" title="" src="graemlins/gr_cry.gif" />
