I'm running it on my 331 which already has everything done to it, heads, cam, intake etc. but I had to upgrade my 30 lbs injectors to 42's to ditch the FMU, changed out my 155lph pump for a 255 lph, went from a Pro-M 75mm bullet mass air to a 80MM Pro_m shorty "blower" mass air meter and purchased a Chipmaster Revolution chip which I had a tune burnt onto.
Are you bolting onto a stock motor? Then as it comes should be good enough for now.

install always takes longer then recommended. It was easy to do but because I ditched both my smog, and power steering and with no a/c I had to take some time to figure out the proper belt routing. If it is a daily driver I would start on the Friday and hopefully be done on Sunday. I've put 2000 miles on it so far, no problems. It has a nice blower whistle at idle, definetely stands out but no overly loud.

Like Mike said.......you may want the extra boost. I'm already looking at changing the pulley. Anyone have any info that for the 1220?
I bought a paxton 1220 sl polished. Got a good deal on it, Jegs had the polished sl listed for less than the satin, plus they had a $250 rebate then.
I havent installed it yet for a few reason, one being that my car has 128k miles. Bunch of parts I want to put on before the s/c.
Like others said, you will prob be getting a fuel pump, ignition retard, bypass valve,etc. Im going to be buying all those things as well before the s/c gets on. However, for how much I paid for the s/c I dont think its worth it to sell and then get a V3 si.
Been cosidering selling the 1220 sl and then forking out the extra cash, what you guys think?
Future plan, 331 short block, trick flow h/c/i, then the sl running 7/8 psi......

well now that you have it I would keep it. I'm very happy with mine. On the 331 the car is animal, it will destroy my 275/60 tires in second gear at 30 mph.
I'll let you know how I do this weekend at the track if it stops raining!

I'm planning on putting the 1220 on my 331 which is 10:5:1 compression 400hp N/A After tons of research I've basically decided that running about 5-6lbs of boost with proper tuning I should be fine detonation wise. I can't wait to get this puppy installed and easily pick up 100+ hp. If I blow it up it just gives me an excuse to build the 408 I've always wanted!!

well your combo is somewhat similar to mine and I have few issues. I HAD to get a chip and a proper tune and run minimum 94 octane. Otherwise no problems.
