From what I've heard, the 112 will be to small for a 402, might have to consider a 122

I think the TCS 1.9 or 2.3 would be best for your setup, since you are running a 402. The MP112 is a little small for an all-out setup.

The price difference through Magnacharger is probably small given the price of the entire kit. If all-out is your goal, I think the TVS series would be the way to go.

Then again, those guys might be giving MP112 kits away to clear out their old inventory... I don't really know. I called them a couple weeks ago for some info and the immediately tried to sell me on the MP112 kits. I had to ask specifically about the TVS kit, and then I got some info on that.

You're going to have issues getting much boost out of a 112 on a 402.

What are your numbers on your current setup? Any track times?

You would be better of with a 346 - 370 block (forged). Torque down low will be nuts. If you are dead set on going with a 402 or have one, you'll have to overspin the maggie to make the power or go with a Procharger or Turbo setup. I loved my maggie though. The lowend is insane.

You would not be happy with anything smaller than a 2300 on your 402. The 112 would not give you the boost you're looking for. Bob

gotcha so 402 is to big for the little maggie, ok so that answers that question, so now 2 my others,(1) what would be the best pistons for it, and (2) i want 2 aim for 650-700 rwhp and maximize the blower, does n e one think my setup that i have listed, in the first thread can produce that much power. like i said n e advice is greatly appericiated, ill try and contact Ed and see if i can get n e info on the TVS kit. as far as my rearend setup goes, im not goin n e where past 3.73 gears assuming i can even hook up with those gears

I really have my doubts that the 2300 will fit.

Check out our complete LS2/402 shortblock, the parts listed in it our what we use and recommend.

3.70 gears are a great way to go. Check out my '99 Camaro at this link, which has 3.70 gears. http://www.exoticperformanceplus.com...Car.php?car=12 Bob

Where can I get info on the big magnuson kit? We don't have to worry about clearing the cowl.

That was on an engine dyno. Its going to take a lot of tuning and a 370-383ci motor and a big damn blower cam and a **** load of boost to get 700 rwhp.

I will prove it within the next 2 mos, Thats the build i'm working on right now.

I think Harrop runs Eaton TVS units just like Magnacharger, but I could be wrong.

I ran a forged 347 with small valve reliefs on mine, 243 heads, blower cam from Comp Cams, Kooks 1 7/8 lts, and spun mine to 10lbs of boost; I used the thicker MLS gaskets too, with a tune from Vengeance when they came out to Hawaii and drove my car to tune it I ended up with 545rwhp and 550rwtq.

I would recommed forged pistons with a slight dish to help drop compression to be able to use more timing and get more power out of your setup. I could have run meth or some other charge to increase the timing, that would've gotten me closer to 600s. A few more cubic inches would help out too, but I would reommend staying under 400, more like 370-383.

The off-idle torque and power wit the maggie kits is insane, mine was a daily driver with tire-smokin capabilities at will. I could be driving 70mph on the freeway turn off the traction control, mat the pedal and send the tires up in a smoke show. Then I decided that I wanted a Vette and let it go, dumbest thing I've ever done!!!!
