Goal to get max whp out of my set up.Car is going to be built for Roll Racing around 60mph. not looking to do much dig runs. So I need mid top end power.

Everything looks good except for the MAF, I'd run your stock one, or ditch the MAF and run in speed density.

i would switch to 1/7 8th headers and tsp duals, i cant tell you how much better my ms4 car pulled with the duals over the lm1, just have extensions made to go back into the cme, thats what im going to do anyway,what gear is goin to be in the car?also have you got these parts yet or looking to get these parts

600 to the floor, tq is always higher on nitrous correct?

The guy I purchased my shortblock from ran trickflow as cast 220cc heads with a futral 13 or whatever the mid 230's cam it is and did a 250 shot and his numbers were... 720ish HP but his torque was 840...

I agree with using the TSP true duals...Much better flowing exhaust but they tend to scrape here and there depending on the quality of the roads in your area. If you already have your Pacesetter's on, I wouldn't go through the traouble of buying another set. Those will be fine up until around 700whp. They will also offer a little better down low power versus the 1 7/8'' but you will pick up more power up top with the 1 7/8'' headers. Heads seem to flow pretty good. Nitrous like the better exhaust ports on the cylinder heads also, I've heard TFS has the best ones in that area. Maybe consider going custom grind camshaft for the extra 10 bucks. Also, you didn't elaborate if you were an A4 or M6. I take it your not an automatic or you would have given converter information. I would STRONGLY advise on a set of gears to accomodate such a big cam. At least some 3.73's. Otherwise, it will suck driving around town. It isn't always about peak numbers bro. Honestly, your gonna have the juice to get you the peak numbers you want. Consider going with a nice street cam for daily use, then when it's play time, turn on the bottle. If it were me, I'd choose a nice 228R or maybe a 228/232. JMO.

I'd go SD for this setup I think.

TransAmcoupe98

Is SD recommended on nitrous applications?

I'm m6 on 373 and nitto dr's.the car is not a daily driver. What can i expect on motor? Is that ms3 great for nitrous?

mark21742

I'd always recomend SD....only thing is if running n2o with SD you need to run a wet kit....preferably direct port so you do not get fuel pooling in your intake.....that would be a time bomb judt waiting to go off.

mark21742

Stock MAF can support 600hp....can't remember what the dtock tb is rated at off hand

I have been told I have to fly cut the pistons due to valve clearence on these heads. they have also been milled a lil. what the biggest cam size I can go without fly cutting
